iPhone X BY (Yacbouz)

Apple’s New Flagship – iPhone X

The iPhone X, pronounced « iPhone 10, » was introduced at Apple’s September 2017 event as a classic « One more thing… » addition to the iPhone 8 and 8 Plus product lineup. According to Apple, the iPhone X represents the biggest technological leap forward since the original iPhone was introduced 10 years ago in 2007, and it sets the path for the next decade of iPhone development.

Apple’s aim with the iPhone X was to create an iPhone that’s all display, blurring the line between physical object and experience. The 5.8-inch front screen melts into a highly polished curved-edge stainless steel band encircling a durable all-glass body available in two pearlescent finishes: Space Gray and Silver. Both feature a black front panel.iphonexdesign-800x669

The edge-to-edge top-to-bottom Super Retina display adopts OLED technology for true-to-life colors, deep blacks, and a million-to-one contrast ratio. It features a 2436 x 1125 resolution and 458 pixels per inch, the highest resolution and pixel density ever introduced in an iPhone. It supports HDRwide color3D Touch, and True Tone for adjusting the white balance of the display to match the ambient lighting.

At 5.8 inches diagonally, the iPhone X has the largest display introduced in an iPhone yet, but with no bezels aside from a notch housing the camera and sensors, it fits comfortably in the hand. At 143.6mm tall by 70.9mm wide by 7.7mm deep, it’s not much bigger than an iPhone 8, and it’s smaller than an iPhone 8 Plus.

The glass body of the device is IP67 water and dust resistantand it enables support for inductive wireless charging for the first time. The iPhone X adopts the Qi wireless standard and can charge through the glass back using any Qi-certified charging accessory. Apple is making an « AirPower » accessory to charge iPhone X, Apple Watch Series 3, and AirPods simultaneously, but it won’t be out until later in 2018.

With an edge-to-edge design, there is no room for a Home button, so the iPhone X adopts a new user experience. A swipe up at the bottom of the screen brings up the Home screen, while a swipe and a hold brings up App Switcher. There’s a Tap to Wake feature for looking at notifications, the side button can be pressed and held to activate Siri, and the Control Center is accessed by swiping downwards from the top status bar.iphone-x-front-back-800x380

No Home button also means no Touch ID, so unlocking the device is done with a new Face ID facial recognition system. Face ID uses the TrueDepth front-facing camera system to create a 3D map of your face that’s used much like a fingerprint for unlocking the iPhone, authenticating Apple Pay purchases, making App Store purchases, and accessing passcode protected apps.

Face ID uses infrared camera technology so it works in the dark. It also uses machine learning and detects your face with hats, glasses, beards, and other objects obscuring your face. Because it uses a 3D map of the face, Face ID cannot be fooled by photos, masks, or other facial replicas. As an added layer of security, Face ID is « attention aware » and unlocks your iPhone only when you’re looking at it.

Face ID is powered by a state of the art dual-core neural engine built into the new A11 Bionic chip, data stored in the Secure Enclave and all processing done on-device. The A11 chip includes a total of six cores, with two performance cores and four high-efficiency cores, including the neural engine.faceidangle-800x644

The performance cores are 25 percent faster than the A10, while the high-efficiency cores are 70 percent faster. An upgraded GPU is 30 percent faster, and there’s 3GB of RAM in the device.

With a second-generation Apple-designed performance controller, all six cores in the A11 chip can be accessed at the same time, resulting in much improved performance, especially when it comes to multi-threaded workloads. The A11 also features a faster GPU, an Apple-designed image signal processor and video encoder, an A11 motion coprocessor, and the Secure Enclave for Face ID.

With efficiency improvements enabled by the A11 Bionic chip, the iPhone X offers two hours more battery life than the iPhone 7, but the battery falls short of the battery in the iPhone 7 Plus.

The same 7-megapixel TrueDepth camera that powers Face ID enables a new feature called Animoji. Animoji are 3D emoji able to mimic your facial expressions. The TrueDepth camera tracks more than 50 facial muscle movements and translates them to the Animoji, which can be used in the Messages app.

iphone-x-display

Apple’s TrueDepth camera also introduces Portrait Mode for the front-facing camera and enables Portrait Lighting, a new feature for adjusting the lighting in a portrait image taken by the front or rear camera.

In the back, the iPhone X features a vertical 12-megapixel dual-lens camera arrangement with an f1.8 wide angle lens and an f/2.4 aperture telephoto lens. Both lenses support optical image stabilization and have improvements like a new color filter, deeper pixels, better low light zoom, and improved video stabilization. Between the cameras, there’s a new quad-LED True Tone flash.

With the individually calibrated cameras, a new accelerometer and gyroscope, tuning for ARKit, and the powerful A11 chip, the iPhone X has been designed for a better augmented reality experience. Developers can take advantage of both the rear camera and the TrueDepth camera to create unique AR apps with unparalleled face tracking capabilities.

iPhone X is available with either 64 or 256GB of storage. The 64GB model is priced at $999, while the 256GB model is priced at $1,199. Apple began accepting pre-orders for the device on Friday, October 27 ahead of an official November 3 launch date.

The iPhone X is Apple’s new high-end flagship device, but it is being sold alongside two other new devices, the iPhone 8 and the iPhone 8 Plus. Both devices are less expensive, but also lack the redesign and the new Face ID system.

 

Pricing and Availability

Apple began accepting pre-orders for iPhone X on Friday, October 27. The device’s official launch date followed on Friday, November 3 in dozens of first wave launch countries. iPhone X availability expanded to additional countries on November 24, and now the device is available for purchase in most countries around the world.

iPhone X orders placed today in the United States ship out and deliver in just a few days. Most retail stores around the world have in-store stock available immediately, and the device is also available from many third-party retailers.

The iPhone X is priced at $999 for the 64GB configuration and $1,149 for the 256GB configuration.iphonexprice-800x173

For customers who use the Apple Upgrade Program, the iPhone X costs $49.91 per month for the 64GB model and $56.16 per month for the 256GB model.

As of December 4, 2017, Apple is selling a SIM-free iPhone X that allows you to purchase an iPhone X without choosing a carrier. The SIM-free iPhone X is compatible with all carriers.

Issues

Cold

Some iPhone X users have discovered the iPhone X can become unresponsive in the cold, refusing to recognize some touch input. Apple says there is a bug in the software causing the problem, and the issue was addressed in the iOS 11.1.2 update. Customers experiencing this problem should update to iOS 11.1.2 or later to fix it.

Green Line

A small number of iPhone X users have seen a green line appearing on the display of the OLED device. The issue causes a bright green line to show up on one side of the device, seemingly at random. It’s not clear what’s causing the line to appear, not whether it’s a hardware or a software issue, but Apple has been replacing affected units.

iphone-x-green-line-duo.jpg

This appears to be an issue affecting only a limited number of iPhone X owners, and Apple has not yet commented on it.

Speaker Crackling

A small number of iPhone X owners have noticed issues with the speaker crackling at loud volumes. There was a similar problem on the iPhone 8 and iPhone 8 Plus that was previously fixed by software updated, but that issue was limited to phone calls. Users who are hearing crackling or static sounds on the iPhone X appear to be hearing it from the earpiece speaker with any high volume sound.

iPhone X Reviews

Reviews of the iPhone X are largely positive, with several reviewers referring to the device as the best iPhone ever made thanks to its edge-to-edge display, sleek design, powerful processor, impressive cameras, and Face ID, which was well received and often accurate for reviewers.

The Verge‘s Nilay Patel said the iPhone X’s display is « polished and tight and clean, » but not flawless, with a tiny ridge between the glass back and the chrome frame, a « huge » protruding camera bump, and the notch in the display.

In regard to the notch, which has been a hot topic of discussion, Patel says it « tends to fade away » in portrait mode. In landscape, though, it’s « definitely intrusive. » Apps need to be optimized to work for the iPhone X, and until they’re updated, work in a « software bezel » mode with borders at the top and bottom.

Most reviewers found that Face ID works well, is quick to unlock the phone, and is dead simple to set up. Business Insider said Face ID unlocked the iPhone X reliably in low light, in bright light, and even in a pitch-black closet.

The Wall Street Journal‘s Joanna Stern also found that it worked in all lighting conditions and with sunglasses and makeup, and it couldn’t be fooled by a photograph or even a detailed silicone mask. Identical triplets were, however, able to fool Face ID.

TechCrunch‘s Matthew Panzarino thought Apple Pay was faster and more natural with Face ID, and autofilling passwords is quicker than ever. He did see Face ID fail, but largely when he wasn’t looking at the iPhone X — it requires eye contact to unlock (but this feature can be disabled in Settings).

Animoji, enabled by the front-facing TrueDepth camera, are « cute » according to CNET, which is about the extent of what reviews had to say about the feature.

No Home button takes some getting used to, according to Mashable‘s Lance Ulanoff, and there are several new gestures to learn to compensate. The Independent‘s David Phelan agreed, and said while the change is straightforward, it « takes time to acclimatize. »

Popular YouTuber MKBHD found the OLED display of the iPhone X, a first for an Apple product, to be bright, « constrasty, » well-calibrated, and not oversaturated like some OLED displays.

As for the rear camera, CNBC‘s Todd Hasselton said it’s better than the camera in the iPhone 8 Plus, while BuzzFeed said the camera is « really good » especially at nighttime, with vivid warm colors in the daytime.

Most reviews thought the iPhone X was worth its price tag as an ultra premium device, but not all people need or want the features that are included, so the decision on whether to purchase comes down to each individual’s budget and desired feature set.

Design

The iPhone X features the first new design Apple has debuted since the iPhone 6 and 6 Plus launched in 2014 with new screen sizes. With the iPhone X, Apple has introduced a display that stretches from edge to edge and top to bottom with minimal bezels for an all-screen design.

Aside from a slim bezel that wraps around the edges of the device and a front notch that houses the front-facing camera, speaker, and sensors, display is all you see when looking at the iPhone X. There is no bottom bezel, no Home button, and no Touch ID fingerprint sensor.

iphonexfrontback-800x573

With the elimination of the bezels, Apple has been able to pack a 5.8-inch display into a body that’s not much bigger than the iPhone 8. The iPhone X measures in at 143.6mm tall by 70.9mm wide, and it is

iphonexsize-800x291

Comparatively, the iPhone 8 measures in at 138.4mm tall, 67.3mm wide, and 7.3mm thick, while the iPhone 8 Plus is 158.4mm tall, 78.1mm wide, and 7.5mm thick. As you can see, the iPhone X is larger than the iPhone 8, but smaller than the iPhone 8 Plus. It is, however, thicker than both devices, but is able to be comfortably held and used with one hand.

The gently rounded edges of the iPhone X’s display meld right into a surgical-grade highly-polished stainless steel frame, which in turn flows into a new glass body for a continuous surface from front to back.

iphonexdesigncorners-800x452

Glass is more fragile than the aluminum that’s been used for the last several iPhone models, but Apple says the front and back glass in the iPhone X is the most durable it’s ever made. The iPhone X has, however, been proven to be prone to shattering in drop tests and has been named Apple’s « most breakable iPhone ever » by warranty site SquareTrade.

The iPhone X comes in Silver and Space Gray, with both colors offering an almost pearlescent finish thanks to a seven-layer ink process that has allowed Apple to introduce precise hues and opacity

iphonexcolors-800x573

A reflective optical layer is added to the glass to enhance the two colors, and an oleophobic coating means smudges and fingerprints can be easily wiped away. The steel frame, designed to reinforce the iPhone X, is made from a special Apple-designed alloy that is more pure for better durability and on each device, the frame matches the body color. Nearly invisible antenna bands cut through the steel frame at the top and bottom of the device to ensure adequate signal.

iphonexaluminumframe-800x50.jpg

The left side of the device houses the standard mute switch and volume buttons, while the right side features an elongated side button that has new functionality to compensate for the removal of the Home button.

iphonexcameradesign-800x321.jpg

At the back of the iPhone X, there’s a dual-lens rear camera arranged in a vertical orientation, a first in an iPhone. The camera continues to protrude slightly from the body of the device, and between the two lenses, there’s a quad-LED flash and a microphone.

The bottom of the device features a traditional Lightning port for charging purposes along with six speaker holes located on either side of it.

WATER AND DUST RESISTANCE

The iPhone X is IP67 water and dust resistant. That means it is impervious to dust and can withstand immersion in water up to one meter (3.3 feet) deep for 30 minutes in laboratory conditions.

appleiphonexinwater-800x714.jpg

Though the iPhone X stands up to splashes, rain, and brief accidental water exposure, intentional water exposure should be avoided. Apple warns that water and dust resistance are not permanent conditions and could decrease as a result of normal wear. Apple’s warranty also does not cover any kind of water damage to iOS device, so it’s best to use caution when exposing the iPhone X to liquids.

IOS 11 INTERFACE CHANGES

With no Home button, Apple has rethought the user interface on the iPhone X, and made improvements that it believes ultimately result in a more intuitive usage experience.

Unlocking the iPhone X is done with a new Face ID facial recognition system, and to get to the Home screen, you simply swipe up from the bottom of the device. A swipe upwards to go back to the Home screen works from within any app, and Reachability can be enabled in Settings and accessed by swiping downwards on the bar at the bottom of the display.

iphonexlockscreen-1-800x523.jpg

Because of the Face ID feature, all text previews are hidden by default on the iPhone X until the device is picked up and unlocked with a facial ID scan, so your text messages remain private.

To get to the App Switcher, swipe upwards and then pause for a second. With the App Switcher, you can switch between apps. You can also swipe on the left and the right of the display to flip between open apps for quick back and forth actions.

iosxinterface-800x633.jpg

At the top of the display, the status bar that displays time, cellular signal, and battery life is split and displayed on either side of the device notch. Swiping downwards from either side of the status bar opens up Control Center.

The notch at the top of the display is the most jarring change to the interface, as it is always visible needs to be accounted for in app designs. Apple is not allowing app developers to conceal the notch with black bars, and developers must design around a safe area on the display to avoid content clipping and interfering with navigation gestures.iphonexhomescreen-800x628.jpg

In landscape mode, the display notch is visible on the left side of the device and is likely to be a distraction until users adjust to the new design. No content is obscured, with Apple using bars in situations like watching videos or viewing webpages in Safari. Photos, videos, and games can all be viewed full screen, though, with the notch cutting into some content in those situations.

iphonexsafaridesign-800x608.jpg

Without a Home button, the side button on the iPhone X does a lot more. Holding down on the button activates Siri, while pressing the side button and the volume up button takes a screenshot. Apple Pay purchases are now confirmed with a double click on the side button.

faceidapplepay-800x485.jpg

To activate the display, you can use the side button, the Raise to Wake feature, or a new « Tap to Wake » feature that turns on the iPhone’s screen when you tap it with a finger.

The iPhone X has its own « Reflection » default ringtone for incoming calls and notifications, which has a soft, mellow twinkling sound that’s unique to the device.

Display

The « Super Retina » display in the iPhone X is the first high dynamic range (HDR) OLED display Apple has incorporated into an iPhone. OLED brings vivid, more true-to-life colors, deep blacks, and a 1,000,000 to 1 contrast ratio.

iphonexdesign-1-800x597

OLED displays traditionally come with tradeoffs like lower brightness, poor color accuracy, and no wide color support, but Apple says has overcome those issues with a « breakthrough » display that features unparalleled quality, responsiveness, and efficiency with support for Dolby Vision, HDR10, wide color gamut, and advanced color management techniques for what Apple says is the best color accuracy « in the industry. »

iphonexdisplay-800x170.jpg

The Super Retina display features a 2436 x 1125 resolution with 458 pixels per inch, the highest resolution and pixel density Apple has introduced in an iPhone. It offers True Tone technology, which uses an ambient light sensor to adjust the white balance of the display to match the ambient lighting in a room. This reduces eyestrain and makes for a more paper-like reading experience

truetoneiphonex-800x626.jpg

At the edges of the device where the display folds into the rounded corners, Apple says it uses folded and circuit stacking technology along with subpixel anti-aliasing for smooth, distortion-free edges.

MINOR SCREEN BURN-IN AND COLOR SHIFTS

According to Apple, with extended long-term use, OLED displays can show « slight visual changes, » aka « image-persistence » or « burn-in, » which is considered normal. The iPhone X has been engineered to be the « best in industry » at reducing burn-in effects, but an Apple support document suggests minor burn-in is still a problem that some users could potentially see over time.

iphonexretinadisplay-800x197.jpg

Apple says burn-in can occur when the same high contrast image is continuously displayed for prolonged periods of time, so the company suggests that users avoid displaying static images at maximum brightness for long periods of time. If there’s an app that keeps the display on when the iPhone X is not in active use, the display’s brightness level should be temporarily reduced using Control Center.

Making sure the iPhone X’s display is set to go to sleep after a short period of time also helps prevent any burn-in issues, as it generally happens when the same image is on the display for a long time. Apple recommends setting Auto Lock to « a shorter time. »

Along with burn-in, Apple says that some shifts in color when looking at the iPhone display from an off-angle is also common with an OLED display and not unusual.

3D TOUCH AND TAPTIC ENGINE

Though it has a new OLED display, the iPhone X continues to support 3D Touch gestures. 3D Touch is available throughout the iOS 11 operating system and is often used to display additional information with a single force press gesture.

A Taptic Engine continues to provide tactile feedback in the form of vibrations when users interact with the display.

Face ID

Face ID is a new facial recognition system that replaces the Touch ID fingerprint sensor used for authentication purposes in earlier devices. In many ways, Face ID is just like Touch ID, except it uses a facial scan instead of a fingerprint. It does all of the same things, like unlocking your iPhone, allowing access to third-party passcode-protected apps, confirming purchases, and authenticating Apple Pay payments.faceidangle-800x644

Face ID uses a set of sensors and cameras built into the front of the iPhone X, and Apple calls this multi-component setup its TrueDepth camera. To create a scan of your face, a Dot Projector projects more than 30,000 invisible infrared dots onto your face. The dot map is read by an infrared camera and the structure of your face is relayed to the A11 Bionic processor in the device where it is transformed into a mathematical model.

iphone-x-truedepth-system-2.jpg

When you get a new iPhone X, Face ID is part of the setup process, much like Touch ID was. Instead of adding a fingerprint to the device, you’ll use Apple’s tutorial to create a quick 3D face scan that’s converted into a series of data points. As with your stored fingerprint, the data from your stored face scan is compared to the data from a new face scan each time you use biometric authentication.

iphonexfaceidsetup-800x579.jpg

It takes just fractions of a second for the iPhone X to scan your face, recognize you, and unlock your device, though Face ID has been described as slower than Touch ID. When measured side by side, Touch ID unlocks an iPhone faster, but Face ID offers an interface that’s ultimately faster in day-to-day use because it’s more streamlined. As an example, opening a notification with Touch ID requires tapping the notification and then putting a finger on Touch ID. With Face ID, the iPhone is unlocking as the notification is tapped.

FACE ID SECURITY AND PRIVACY

Because Face ID takes a detailed 3D facial scan, it’s unable to be fooled by a photo, a mask, or other facial imitation, and there’s also an « attention aware » security feature. Face ID only unlocks your device when you look in the direction of the iPhone X with your eyes open, meaning Face ID knows not to work unless there’s a live person in front of it

faceidscaniphonex-800x493.jpg

Face ID won’t work when your eyes are closed, when you’re sleeping, when you’re unconscious, or when you’re looking away from your phone.

Attention aware is optional and there is an accessibility feature to turn it off for those who are unable to focus on the iPhone’s screen, but most people will want to leave it turned on for the added layer of security.

If a thief demands your iPhone, Face ID can be disabled quickly and discretely by pressing on the side button and the volume button at the same time. Do this before handing your phone over, and a thief won’t be able to scan your face. Face ID also turns off after two failed facial recognition attempts and a passcode needs to be entered for it to be turned back on.

Face ID is encrypted and stored in the Secure Enclave on the iPhone X. Apple can’t access your Face ID data, nor can anyone who gets ahold of your phone. Authentication happens entirely on your device, with no Face ID data ever stored in the cloud or uploaded to Apple.

iphonextruedepthcamera-1-800x437.jpg

Apple says Face ID is more secure than Touch ID because there’s less chance of a mismatch. There’s a 1 in 50,000 chance someone else can unlock your iPhone with their fingerprint, but a 1 in 1,000,000 chance someone else’s face can fool Face ID. For identical twins, though, the error rate increases.

YouTube videos have surfaced featuring the iPhone X fooled by twinschildren, and even a carefully crafted 3D printed mask, but the feature is still secure enough that the average person does not need to worry about it being unlocked by someone else.

Third-party app developers don’t have access to the facial map that Face ID uses to unlock a device, but they are able to use the TrueDepth Camera to scan a user’s face for the purpose of creating more realistic augmented reality apps. Developers are able to see a 3D face mesh and detected 52 micro-movements for determining expression, which is worth being aware of if you’re an iPhone X owner.

While Face ID works in the same way as Touch ID and largely does all of the same things, at the current time, Face ID cannot be used to approve family purchases on the iPhone X. This means parents must enter a password to approve an App Store purchase when a child requests permission to buy something. On phones with Touch ID, a fingerprint scan is able to replace a password. Apple is addressing this issue in iOS 11.3 and enabling the ability to approve family purchases with Face ID.

FACE ID IN THE DARK

Because Face ID uses infrared, it works in low light and in the dark. Apple has built a Flood Illuminator into the TrueDepth camera to make sure there’s always adequate infrared light to take a scan of your face.

iphonexdotcounter-800x655 (1).jpg

You don’t need to hold your iPhone right in front of your face for Face ID to work. It can work from multiple angles so you can hold it at a comfortable position as you might when just casually looking at the screen. It won’t unlock in your pocket like it does with Touch ID, but as soon as you take it out and go to look at the screen, it’s ready to go.

FACE ID WITH HATS AND SUNGLASSES

Face ID works with hats, beards, glasses, sunglasses, scarves, makeup and all other accessories and items that might partially obscure a face. Face ID needs to see your eyes, nose, and mouth to work, so things like the surgical masks doctors wear prevent Face ID from working.

When it comes to sunglasses, Face ID works with most sunglasses, with the exception of some that may have a coating that blocks infrared light.

faceidhatscarf-800x549.jpg

All of Face ID’s facial recognition capabilities are powered by a two-core neural engine built into the A11 Bionic chip, which uses machine learning to detect your face and recognize changes in your appearance, like longer hair, beard growth, or a hat.

FACE ID APPLE PAY

Face ID replaces Touch ID when authenticating Apple Pay purchases. When checking out with Apple Pay, a glance at the iPhone X authenticates a payment, and a double click on the side button of the device confirms it.faceidapplepaycash-800x570.jpg

With the « attention aware » feature, the iPhone X knows when you’re looking at it. Face ID displays notifications and messages on the Lock screen when you look at the iPhone X, it keeps the screen lit, and it automatically lowers the volume of an alarm or ringer when it knows your attention is on the iPhone X’s display.

A11 Bionic Processor

The iPhone X is powered by a 10-nanometer six-core 2.4GHz A11 Bionic chip designed by Apple. The A11 Bionic chip features two performance cores and four high-efficiency cores, all of which can be harnessed at the same time thanks to a second-generation performance controller resulting in 70 percent better performance for multi-threaded workflows and much better battery life.

a11bionicchip-800x595

Apple says the two performance cores in the A11 are 25 percent faster than the A10, while the efficiency cores are 70 percent faster. Those speed increases have been reflected in early benchmarks, with the A11 in the iPhone X and iPhone 8 earning an average single-core score of 4169 and an average multi-core score of 9836.

a11geekbench-800x706.jpg

Based on those scores, the A11 chip outperforms the A10 in previous-generation devices by a wide margin, and it also outperforms the A10X in the iPad Pro. In fact, it’s close to the performance of the highest-end 3.5GHz 2017 13-inch Retina MacBook Pro model.

The A11 chip features a new Apple-designed three-core GPU that’s 30 percent faster than the A10 in the iPhone 7, for much improved graphics performance, and it includes an embedded M11 Motion coprocessor that captures motion-based data from the compass, accelerometer, and gyroscope to power fitness capabilities, augmented reality experiences, and more, without significant power drain.

iphonexar-800x399

 

A11 BIONIC NEURAL ENGINE

Two of the cores in the A11 Bionic chip are dedicated to a neural engine able to process more than 600 billion operations per second. The neural engine is what powers Face ID and other machine learning tasks.

RAM

The iPhone X features 3GB RAM, like the iPhone 7 Plus and iPhone 8 Plus.

Inductive Wireless Charging

Apple chose glass for the body of the iPhone X to enable inductive wireless charging. Apple is using the Qi wireless charging standard that is also available in many Android phones, which means the iPhone X can charge wirelessly using any Qi-certified inductive charging device.

Inductive charging requires the body of the iPhone to be placed against a charging mat, with the iPhone X charging at a maximum of 7.5 watts. Though there are already many Qi wireless charging accessorieson the market, companies like Belkin and Mophie created charging accessories designed specifically with Apple’s iPhones in mind.

iphone8wirelesscharging-800x649

 

As of iOS 11.2, the iPhone X, iPhone 8, and iPhone 8 Plus support faster 7.5W wireless charging using compatible third-party wireless chargers. Not all wireless chargers support 7.5W, so it’s best to make sure wattage is listed before making a purchase.

In our testing, which compared several wired and wireless charging methods, wireless charging is similar to charging with the standard 5W iPhone charger, but it is slower than other charging methods, such as charging with the 12W iPad adapter and USB-C fast charging.

iphonexchargingtestsocial-800x555.png

7.5W wireless charging is faster than 5W wireless charging in some cases using supported 7.5W chargers, but there are a lot of factors that influence the speed of wireless charging so the difference isn’t always evident. Wireless charging is convenient and best suited to overnight charging and situations where you don’t immediately need an infusion of power. If you’re looking for a wireless charger, make sure to check out our roundup that covers many of the currently available options.

Qi-based wireless charging accessories can also be found in restaurants, coffee shops, and other locations, and these spots charge the iPhone X too. Inductive charging works with most iPhone cases on the market, including Apple’s own cases, so the iPhone X won’t need to be removed from a case to charge.

AIRPOWER

Apple is working on its own wireless charging accessory for the iPhone X, the AirPower, but it won’t be out until later in 2018 because Apple is developing new charging technology able to charge multiple devices at once. No pricing has been unveiled for the AirPower, but a website listing has suggested it could start around $199.

apple-airpower-800x573

The AirPower charging mat will charge the iPhone X, the Apple Watch Series 3, and the AirPods in a new wireless AirPods case.

Cameras

Both the front and rear cameras in the iPhone X have been redesigned compared to the cameras in the iPhone 7, introducing some impressive new functionality and much improved picture taking capabilities.

TRUEDEPTH CAMERA

The 3D TrueDepth front-facing camera system is what powers Face ID with its included infrared camera and sensors, but there’s also a high-quality 7-megapixel camera for taking selfies. The f/2.2 camera supports features like wide color capture, 1080p HD video recording, auto image stabilization, Retina Flash using the display, and auto HDR.

truedepthcamera-800x463.jpg

With the new 3D hardware in the TrueDepth camera, Apple has added Portrait Mode to the front-facing camera as well as the rear camera. With Portrait Mode, the front-facing cameras create a depth map of an image that allows for shallow depth-of-field effects to be applied to photos in real time, making the subject of a photo « pop » out of the background.

truedepthportraitmode-800x579.jpg

Shallow depth-of-field is normally a feature reserved for DSLRs, but Apple uses dual cameras, machine learning, and intensive software processing to mimic the effect.

ANIMOJI

The TrueDepth camera also enables a fun new feature called « Animoji, » aka animated, 3D emoji characters that you control with your face. To create Animoji, the TrueDepth camera analyzes more than 50 muscle movements in different areas of the face, detecting movement of the eyebrows, cheeks, chin, eyes, jaw, lips, eyes, and mouth.

All of your facial movements are translated to the Animoji characters, making them reflect your expression and emotion. Animoji can be shared with friends in the Messages app as stickers and as videos, and you can even add your own voice to make them talk.

There are 12 different Animoji to choose from, modeled after existing emoji characters: monkey, robot, cat, dog, alien, fox, poop, pig, panda, rabbit, chicken, and unicorn.

REAR CAMERA

The rear iPhone X camera features a dual-lens arrangement in a vertical orientation, a first in an iPhone. There’s a standard f/1.8 aperture 12-megapixel wide-angle lens, and a f/2.4 aperture 12-megapixel telephoto lens.

iphonexrearcamera2-800x369

Apple is using an improved 12-megapixel sensor in the iPhone X, along with a new color filter and deeper pixels, but it’s not really clear what Apple means by « deeper pixels. »

The iPhone X features a new Apple-designed image signal processor that’s able to better detect the elements in a scene, including people, motion, and lighting, to optimize photos before they’re captured. The image signal processor also brings advanced pixel processing, wide color capture, faster autofocus, and improved HDR.

iphonexrearcamera-1-800x459.jpg

Most notably, the telephoto camera in the iPhone X now supports optical image stabilization, meaning both lenses support the feature for better photo quality and improved low light performance. Low light performance in the iPhone X’s telephoto lens has shown significant improvement over the telephoto lens in the iPhone 7 Plus in testing.

Sandwiched between the two camera lenses is a Quad-LED True Tone Flash with a new Slow Sync feature that combines a slow shutter speed with a strobe pulse for a brighter foreground subject and properly exposed background in low lighting conditions.

The flash also delivers more uniform illumination for better performance all around.

PORTRAIT LIGHTING

Portrait Lighting is a new Portrait Mode feature that’s available on both the front and rear-facing cameras in the iPhone X. Portrait Lighting is designed to let you add studio-quality effects to your images.

iphonexportraitlighting-800x465

Apple says Portrait Lightning uses sophisticated algorithms to calculate how facial features interact with light, using the data to create unique lighting effects like Natural Light, Studio Light (lights up your face), Contour Light (adds dramatic shadows), Stage Light (spotlights your face against a dark background), and Stage Light Mono (Stage Light, but in black and white).

VIDEO CAPABILITIES

The iPhone X can capture 4K video at up to 60 frames per second, and 1080p slo-mo video at up to 240 frames per second. Advanced video stabilization techniques with larger sensor and the more powerful image signal processor add more stabilization to videos to reduce motion blur and shakiness.

Apple has added a new video encoder that’s able to do real-time image processing for optimal quality, and there’s native support for HEVC compression for the same video quality with smaller file sizes.

Battery Life

Thanks to efficiency improvements introduced with the A11 Bionic chip, the iPhone X lasts two hours longer than the previous-generation iPhone 7 or the new iPhone 8, but it falls just a bit short of the iPhone 7 Plus and the iPhone 8 Plus. The iPhone X uses a 2,716 mAh battery, which is much higher capacity than the 1,821 mAh battery in the iPhone 8.

iphonexiphonebatterycomparison-800x439.jpg

The iPhone X offers up to 21 hours of talk time, 12 hours of internet use, 13 hours of video playback, and 60 hours of audio playback.

The iPhone X features a two-cell battery in an L-shape design with a capacity of 2,716 mAh, slightly larger than the 2,675 mAh battery in the iPhone 8 Plus. The dual setup is what allows the device to have a longer battery life than the iPhone 8.

iphone-x-battery-ifixit-800x586.jpg

The iPhone 8, iPhone 8 Plus, and iPhone X use a « different performance management system » than older iPhones, which means any performance management features may be less noticeable on these devices.

The three devices use a more advanced hardware and software design that’s better able to estimate power needs and battery performance, so in the future, they made not need the same processor-throttling performance management features implemented in older iPhones.

FAST CHARGING

The iPhone X is « fast-charge capable, » which means it can be charged to 50 percent battery life in 30 minutes. Fast charging requires the iPhone X to be plugged into Apple’s 29W, 61W, or 87W USB-C Power Adapters, which are sold alongside its USB-C MacBook and MacBook Pro models.

USB-C to Lightning cable is also required to go along with the USB-C Power Adapter, and the minimum price for those accessories is $74.

Connectivity

LTE ADVANCED

The iPhone X features LTE advanced for data transfer speeds up to 450Mb/s. It offers support for more than 20 LTE bands, which makes it more likely to be able to work with networks in other countries when traveling.

As with the previous-generation iPhone 7 and the iPhone 7 Plus, Apple is using some chips that are not compatible with the CDMA networks of Verizon and Sprint in the United States.

T-Mobile and AT&T iPhones are not compatible with the Verizon and Sprint because they only work with GSM networks. Verizon and Sprint iPhones support both GSM and CDMA networks and are compatible with T-Mobile and AT&T.

Model A1865 supports GSM and CDMA and is designed for Sprint/Verizon, while Model A1901 does not support CDMA networks.

According to wireless signal testing, iPhone X models equipped with Qualcomm’s Snapdragon X16 modem get consistently better LTE speeds than iPhone X models equipped with Intel’s XMM7480 modem.

The speed difference is most noticeable in weak signal conditions, with the Qualcomm iPhone X experiencing 67 percent faster LTE download speeds on average compared to Intel models. Both the Intel and Qualcomm iPhone X models have peak theoretical download speeds of 600mb/s in most countries, however, and the difference in LTE chips is not a major issue in real world usage.

BLUETOOTH AND WI-FI

iPhone X supports the new Bluetooth 5.0 standard. Bluetooth 5.0 offers longer range, faster speeds, larger broadcast message capacity, and better interoperability with other wireless technologies.

Compared to Bluetooth 4.2, Bluetooth 5 offers four times the range, two times the speed, and eight times the broadcast message capacity.

802.11ac Wi-Fi with MIMO is supported, with support for connection speeds that can reach a theoretical maximum of 866Mb/s.

GPS AND NFC

In addition to the Global Positioning System operated by the U.S. government, the iPhone X adds support for Galileo, Europe’s Global Satellite Navigation System, and QZSS, the Quasi-Zenith Satellite System used in Japan.

Galileo support in the iPhone X lets users to benefit from more precise positioning that’s able to combine GPS, GLONASS, and Galileo signals. Galileo, says the agency, has a modern signal structure that’s able to help users better maintain their position fix when navigating through cities worldwide.

As for NFC, there’s a new NFC chip with a reader mode that lets the iPhone X read NFC tags in places like retail stores, museums, and more.

Beyond the iPhone X

The iPhone X will be followed by a second-generation 5.8-inch OLED iPhone, a 6.5-inch OLED iPhone, and a 6.1-inch low-cost LCD iPhone in 2018. To read more about Apple’s plans for the future of the iPhone,

Samsung Galaxy S8 et S8+ : prix, disponibilité et caractéristiques du futur flagship

Après la fin abrupte de la commercialisation du Galaxy Note 7 en fin d’année dernière, nous attendons le prochain smartphone haut de gamme de Samsung de pied ferme. Nous réunissons ici tous ce que l’on connait sur le Samsung Galaxy S8 avant son officialisation en mars.Samsung-Galaxy-S8-Evleaks-2-630x525

Mise à jour du 24 mars : Le Samsung Galaxy S8 n’en finit plus de se montrer. Des visuels nous ont dévoilé les différents coloris que proposera la marque, ce qui nous a aussi donné l’occasion de constater que la façade avant restera toujours noire. Evan Blass a aussi partagé des visuels promotionnels mettant en avant son écran borderless et son appareil photo. Afin de prolonger la durée de vie de la batterie du Galaxy S8, il sera possible de réduire la définition de celui-ci. La batterie externe du Samsung Galaxy S8 sera compatible avec la recharge rapide en USB Type-C. Nous en avons appris davantage sur le dock qui permettrait de transformer le S8 en ordinateur de bureau, celui-ci devrait être composé d’un ventilateur de refroidissement. Samsung imagine déjà le carton plein que ferait les ventes de son futur flagship et propose d’ailleurs à ceux qui le précommande de le recevoir bien en avance. Une nouvelle version de Samsung Pay va permettre d’utiliser le scanner d’Irisdu Samsung Galaxy S8 pour renforcer la sécurité lors du paiement. Son appareil photo pourrait être capable de filmer à 1000 images par seconde.

Ecran AMOLED incurvé et sans bordures

Samsung travaillerait sur deux variantes pour son prochain flagship, le Galaxy S8 et le Galaxy S8 Plus avec un écran plus grand. Voici leurs caractéristiques, confirmées par le leaker Evan Blass, mais aussi par le site BGR qui a fait fuiter toute une série de photos du terminal.

  • Samsung Galaxy S8 : écran 5,8 pouces Super AMOLED incurvé sans bordures QHD (équivalents à 2 880 x 1 440 pixels)
  • Samsung Galaxy S8 Plus : écran 6,2 pouces Super AMOLED incurvé sans bordures QHD (2 880 x 1 440 pixels)C’est sans aucun doute le plus grand changement opéré par Samsung entre le Galaxy S7 et le Galaxy S8 et celui se verra le plus. Face au Xiaomi Mi Mix, Samsung réplique avec lui aussi un écran qui rogne sur les bordures de l’appareil. Fini le modèle équipé d’un écran plat, les deux variantes du Galaxy S8 auront des écrans incurvés, de type Edge.Ces deux caractéristiques permettront à Samsung d’agrandir la diagonale, qui passe de 5,2 à 5,8 pouces et de 5,5 à 6,2 pouces, sans changer la taille de l’appareil. L’écran changera également de format et passera du 16/9 au 18,5/9 ce qui se traduit par un écran qui gagne surtout en hauteur en mode portrait.

    Il faut toutefois garder à l’esprit que l’affichage utile sera légèrement moindre à cause des boutons de navigations qui deviennent virtuelles et des des bords incurvés. On a ainsi pu voir l’interface en action dans plusieurs vidéos, ce qui nous confirme que Samsung a aussi pensé aux gauchers ! EVLeaks a également publié le premier rendu presse (3D) du smartphone.

    Toujours sur l’interface, on peut également apercevoir les icônes et le style graphique choisi pour le Galaxy S8 dans de nouvelles captures d’écran.

    Une source indique par ailleurs que pour pallier l’absence de bouton physique en façade, Samsung aurait choisi d’intégrer un écran Force Touch. Pour rappel, cela permet d’activer des fonctionnalités et des raccourcis en fonction de la pression exercée sur l’écran.  Sur le Galaxy S8, le Force Touch ne se concentrerait que sur le bouton Accueil (logiciel).

    Processeur Exnyos 8895 ou Snapdragon 835

    Le Samsung Galaxy S8 et S8 Plus intégreront pour la première fois des SoC gravés en 10 nm. Le fabricant devrait à nouveau faire varier le processeur selon les régions :

    • En Europe : le processeur Samsung Exynos 8895
    • Ailleurs : le processeur Qualcomm Snapdragon 835Si, comme chaque année, il devrait y avoir quelques différences de performances entre le modèle équipé du Qualcomm Snapdragon et celui intégrant une puce Samsung Exynos, on peut tout de même généraliser sur certains points. Peu importe le processeur utilisé, il sera gravé en 10 nm, une exclusivité sur le marché que Samsung fait fabriquer dans ses propres usines.Cela devrait permettre au Galaxy S8 de proposer une hausse de performance de 11 % pour le processeur et 23 % pour la puce graphique comparée au Galaxy S7, tout en étant plus efficient en énergie de 20 %.

      Le stockage fourni augmente

      Samsung va revoir à la hausse le stockage de son terminal haut de gamme :

      • de 64 Go à 256 Go de stockage interne en UFS 2.0
      • De 4 à 6 Go de RAM LPDDR4
      • Lecteur de carte micro SDEn 2016, Apple s’est enfin décidé à augmenter le stockage de son iPhone qui passe de 16 Go minimum, sans microSD, à 32 Go. Samsung voudrait donc conserver son avance en passant le stockage interne minimum du Samsung Galaxy S8 à 64 Go, contre 32 Go pour le Galaxy S7. Ce stockage pourrait monter jusqu’à 256 Go pour les modèles les plus chers. Certains parlent également d’un modèle équipé de 128 Go de stockage et 6 Go de RAM.Le lecteur micro SD qui avait disparu à l’époque du Galaxy S6 pour faire son retour avec le Galaxy S7 sera toujours de la partie. Samsung semble avoir bien retenu la leçon et continuera de proposer d’étendre le stockage à moindre coût.

        Double système de biométrie

        Le Samsung Galaxy S8 fera appel à un double système de biométrie :

        • un lecteur d’empreinte digitale
        • un scanner d’irisL’écran sans bordures du Galaxy S8 a contraint Samsung à déplacer le lecteur d’empreinte à l’arrière de l’appareil. Il sera situé à côté de l’appareil photo et non en dessous comme c’est le cas chez la concurrence. Un emplacement qui semble se confirmer par de nouvelles photos de coques prévues pour le Galaxy S8. À noter que le fabricant a très probablement pris cette décision à la dernière minute.Le fabricant va également rajouter une seconde couche d’authentification biométrique avec un scanner d’iris que l’on avait déjà vu dans le Lumia 950 de Microsoft et plus récemment dans le Samsung Galaxy Note 7. Il permettra de déverrouiller son téléphone avec des gants et d’améliorer la sécurité dans le cas des paiements sans contact. Les coques de la marque UAG confirment d’ailleurs la présence du scanner d’Iris et le capteur d’empreintes.Sachez également que le Samsung Galaxy S8 pourrait aussi embarquer un système de reconnaissance faciale pour proposer davantage de fonctionnalité pour déverrouiller le téléphone.

          Une connectique complète

          La connectique du Galaxy S8 serait pour le moins complet et le fabricant n’aurait pas fait de compromis :

          • port USB Type-C en USB 3.0 et compatible DisplayPort
          • port audio jack
          • lecteur de carte micro SDSamsung ne suivra pas la voie d’Apple, le Galaxy S8 disposera encore d’un port jack. Le téléphone sera également le premier Galaxy S à intégrer un port USB Type-C, après qu’il soit apparu dans le Galaxy Note 7 et dans le Galaxy A5 2017.Le connecteur ne fait pas tout et Samsung irait jusqu’au bout des promesses de l’USB Type-C en intégrant les technologies USB 3.0 et DisplayPort qui devrait débloquer de nouveaux usages pour le téléphone.

            Résumons la question du design

            Une fois que l’on a vu point à point les caractéristiques techniques du Samsung Galaxy S8, le design de l’appareil devient une évidence. On retiendra ces points :

            • un écran qui occupe plus de 83 % de la surface avant
            • une façade avant toujours noire
            • des coloris « Black Sky », « Orchid Grey », « Artic Silver », doré
            • le design incurvé, jusque-là réservé au modèle Edge, sera généralisé
            • le téléphone devrait faire la même taille que la génération précédente
            • le lecteur d’empreinte sera placé à côté de l’appareil photo
            • le port jack n’est pas abandonné
            • Une résistance à l’eau et la poussière IP68
            • caméra capable de filmer à 1000 images par secondesamsung-galaxy-s8-plus-630x525.jpgPour le moment, une seule photo crédible a fuité concernant le Samsung Galaxy S8. De nombreuses images ont circulé, venant souvent d’accessoiriste, mais ont été démenties par plusieurs sources connaissant les plans de Samsung.

              Appareil photo similaire à l’an dernier

              On a longtemps pensé que Samsung adopterait le système de double appareil photo que l’on retrouve sur beaucoup de mobiles haut de gamme. Au final le capteur du Galaxy S8 devrait être très proche de celui du Galaxy S7.samsung-galaxy-s8-fake-render-630x277.jpg

              ’appareil photo arrière serait toujours équipé d’un capteur de 12 mégapixels f/1.7, mais celui à l’avant gagnerait en définition. Les selfies ne seront plus capturés en 5 mégapixels, mais en 8 mégapixels.

              Bien sûr, la photographie reste l’un des meilleurs arguments de vente d’un smartphone et Samsung va donc légèrement améliorer son appareil, avec des optimisations sur les photos prises en basse luminosité, ou sur la rapidité de capture, mais les changements devraient être mineurs.

              Après tout, le Samsung Galaxy S7 était déjà équipé de l’un des meilleurs appareils photo du marché.

              Une batterie qui doit être fiable

              Après l’accident du Samsung Galaxy Note 7, il n’est pas question de recommencer les mêmes erreurs pour Samsung avec le Galaxy S8. Sa capacité aurait été fixée à environs :

              • 3000 mAh pour le Galaxy S8
              • 3500 mAh pour le Galaxy S8 PlusBattery-630x420.jpgLa batterie est sans doute la pièce la plus sensible sur lequel Samsung a travaillé pour son nouvel appareil. La marque avait annoncé après la fin de l’enquête sur le Galaxy Note 7, une série de mesure pour améliorer la fiabilité de ce composant. Cette série de mesures fait à présent le sujet d’une publicité visant à rassurer le public concernant ses produits.Samsung se serait, entre autres, tourné vers un nouveau fournisseur japonais pour continuer de diversifier les sources d’approvisionnement.

                Pour prolonger la durée de vie de sa batterie interne, nous serons en mesure de réduire la définition.

                La batterie externe développée par Samsung sera par ailleurs compatible avec la recharge rapide et en USB Type-C.

              • Samsung DeX : transformer le Galaxy S8 en PC

                Avec Samsung DeX, les utilisateurs du Samsung Galaxy S8 pourront se servir de leur smartphone comme un ordinateur de bureau.samsung-galaxy-continuum-mockup-2-630x337.jpg

                L’intégration de l’USB Type-C et la prise en charge native du DisplayPort ont permis à Samsung de développer une nouvelle fonctionnalité qui transforme le Galaxy S8 en véritable ordinateur de bureau. Une fois le téléphone connecté à un clavier, une souris et un écran, Samsung DeX permettra d’afficher un vrai bureau similaire à celui de Windows.

                L’utilisateur pourra interagir avec les applications Android en mode fenêtre au clavier et à la souris comme il le fait avec un ordinateur classique. L’arrivée des applications Android sur Chrome OS ont justement permis de pousser les développeurs à prendre en compte ces périphériques, inhabituels sur mobile.

                Avec le Galaxy S8, Samsung commercialisera un dock officiel permettant de relier plusieurs périphériques en USB, ainsi qu’un écran en DisplayPort, mais d’autres accessoires pourraient voir le jour chez des vendeurs tiers. Le téléphone devrait également prendre en charge l’affichage sans-fil par Miracast et le Bluetooth pour tout connecter sans aucun câble.

                Le site WinFuture a dévoilé entre autres que le dock serait équipé d’un ventilateur de refroidissement.

                Fiche technique

                Si l’on réunit toutes les informations, voilà à quoi devraient ressembler les caractéristiques techniques du nouveau flagship de Samsung puisque les fiches techniques ont fuité sur Internet. D’abord le Samsung Galaxy S8 :

                • Écran incurvé borderless de 5,8 pouces Super AMOLED QHD (2560 x 1440 pixels)

                • Batterie entre 3000 et 3 250 mAh
                • Numéro de modèle SM-G950

                Voici maintenant ce que l’on sait sur le grand modèle que l’on surnommera Samsung Galaxy S8 Plus :

                • Écran incurvé borderless de 6,2 pouces Super AMOLED QHD (2560 x 1440 pixels)
                • Taille similaire au Galaxy S7 Edge
                • Processeur Samsung Exynos 8895

                • Numéro de modèle SM-G955

Samsung confirme le problème de batterie du Galaxy Note 7

Comme cela avait été annoncé la semaine dernière, Samsung a dévoilé les résultats de son enquête sur les problèmes techniques sur le Galaxy Note 7 et les raisons de sa surchauffe. Sans surprise, il s’agit de la batterie, comme l’avait annoncé le Wall Street Journal.

La semaine dernière, Samsung annonçait la mise en place d’une conférence de presse pour annoncer les résultats de son enquête interne sur les raisons de la surchauffe du Galaxy Note 7. Un problème technique qui a amené la firme coréenne a remplacé les premières series de phablettes avant de la retirer définitivement des étals des boutiques. Fin de semaine dernière, le Wall Street Journal dévoilait en partie les résultats de cette enquête qui a été menée par Samsung, mais aussi par trois bureaux indépendants. La fuite du quotidien américain affirmait que les batteries seraient officiellement mises en cause. Et ce fut le cas.2017-15-3--19-14-07

Deux batteries, deux problèmes

Samsung a honoré son rendez-vous et a dévoilé les résultats de son enquête. Sans surprise les batteries de SDI (la filiale de Samsung chargée de produire les batteries) et d’Amperex sont concernées. Toutefois, le problème n’est pas le même dans les deux cas de figure. Pour les batteries développées par Samsung, le problème serait une déformation du composant qui aurait amené à un court-circuit. Et c’est ce court-circuit qui aurait provoqué la surchauffe et l’explosion de la batterie. Dans le second cas, le problème serait une malfaçon : un des composants internes de la batterie (une couche isolante entre deux parties conductrices) serait manquant. Voilà pour les deux causes.
Samsung Electronics se défausse en revanche de la responsabilité du problème. Le design du Galaxy Note 7 n’est pas un problème selon la firme. La place laissée à la batterie (trop exigüe, selon certains) n’est en aucun cas l’une des causes de surchauffe, alors que nous savons bien que la batterie est l’un des éléments qui produisent le plus de chaleur dans un téléphone et qu’elle doit être capable de la dissiper. Or, si la place qui lui est laissée est trop petite, ce n’est pas possible. Bien sûr, l’argument de la malfaçon des batteries, qu’elles proviennent de SDI ou Amperex, élimine presque toute responsabilité des designers de la branche mobile du groupe. C’est tout de même bien pratique. Espérons qu’à long terme, ce soit vrai.

Une débauche de moyen
Lors de sa conférence de presse, Samsung a largement évoqué le sérieux avec lequel elle a enquêté sur le problème et les conséquences industrielles que cela amènera lors de la conception des futurs terminaux. Tout d’abord, Samsung a évoqué les moyens financiers et humains monopolisés durant cette enquête : 700 ingénieurs ont travaillé sur 200 000 Galaxy Note 7 différents et 30 000 batteries pour reproduire les problèmes de surchauffe et en comprendre les causes. Ensuite, Samsung a réitéré les nouveaux points de contrôle qui assureront la qualité des futurs produits de la firme coréenne. Le Galaxy S8 devrait être le premier à en bénéficier.
