1 Year Warranty
iPhone X (Roman numeral "X" pronounced "ten", although colloquially, sometimes pronounced as the name of the letter)[9][10] is a smartphone designed, developed, and marketed by Apple Inc. It was the eleventh generation of the iPhone. It was announced on September 12, 2017, alongside the iPhone 8 and iPhone 8 Plus, at the Steve Jobs Theater in the Apple Park campus. The phone was released on November 3, 2017, marking the iPhone series' tenth anniversary.
The iPhone X is intended to showcase
what Apple considers technology of the future, specifically adopting OLED
screen technology for the first time in iPhone history, as well as using a
glass and stainless-steel form factor, offering wireless charging, and removing
the home button in favor of introducing a new bezel-less design, almost
removing all the bezels in the smartphone and not having a "chin",
unlike many Android phones. It also released a new type of password
authentication called Face ID. Face ID is a new authentication method using advanced
technologies to scan the user's face to unlock the device, as well as for the
use of animated emojis called Animoji. The new, nearly bezel-less form factor
marks a significant change to the iPhone user interaction, involving
swipe-based gestures to navigate around the operating system rather than the
typical home button used in every previous iteration of the iPhone lineup. At
the time of its November 2017 launch, its price tag of US$999 also made it the
most expensive iPhone ever, with even higher prices internationally due to
additional local sales and import taxes.
The iPhone X received mixed reviews.
Its display and build quality were universally praised, and the camera also
scored positively on tests. The phone received particularly polarized reception
due to the sensor housing "notch" at the top of the screen and the
introduction of an all-new authentication method. The notch was heavily mocked
by users on social media, although app developers responded either neutrally or
positively to the changes it brought to the user experience in their apps and
games. Reviewers had mixed reactions, with some condemning it and others
acknowledging it as unusual in the first moments of use before getting
accustomed to its presence. Face ID facial recognition was praised for its
simple setup, but criticized for requiring direct eyes on the screen, though
that option can be disabled within the system preferences.
Along with the iPhone 6s, its Plus
variant, and the iPhone SE, the iPhone X was discontinued on September 12, 2018
following the announcement of the new iPhone XS, iPhone XS Max and iPhone XR
devices. As a result, with a shelf life of just over 10 months, the iPhone X
had the shortest ever tenure as the flagship device in the history of the
iPhone.
On November 22, 2018, Apple has
reportedly resumed production of the iPhone X due to weak sales of it
successors. The iPhone X will not be available to buy on the Apple website and
remains discontinued.[11]
History
The technology behind the iPhone X
was in development for five years, as far back as 2012.[12] Rumors
of a drastic iPhone redesign began circulating around the time of iPhone 7
announcement in the third quarter of 2016,[13][14] and intensified
when a HomePod firmware leak in July 2017 suggested that Apple would shortly
release a phone with a nearly bezel-less design, lack of physical home button,
facial recognition, and other new features.[15] A near-final
development version of the iOS 11 operating system was also leaked in September
2017, confirming the new design and features.[16]
On August 31, 2017, Apple invited
journalists to a September 12 press event,[17][18] the first public
event held at the Steve Jobs Theater on the company's new Apple Park campus in
Cupertino, California.[19][20][21] The iPhone X was unveiled during
that keynote. Its US$999 starting price is the most expensive iPhone launch
price.[22] The price is even higher in international markets due to
currency fluctuations, import fees and sales taxes.[23]
An unlocked version of the phone was
made available for purchase in the United States on December 5, 2017.[24][25]
In April 2018, the Federal
Communications Commission divulged images of an unreleased gold-colored iPhone
X model.[26] As opposed to the space gray and silver color options
that the iPhone X ships with, it was divulged that there were initial plans to
release a gold option for the device. However, it was put on hold due to
production issues.[27]
Apple did release a new revision
iPhone X, the B model that fixed NFC issues for users in Japan, China, and some
in America. [28]
Specifications
Hardware
The iPhone X has a 5.8-inch OLED
color-accurate screen that supports DCI-P3 wide color gamut, sRGB, and high
dynamic range,[29][30] and has a contrast ratio of 1,000,000:1.[31]
The Super Retina display has the True Tone technology found on the iPad Pro,
which uses ambient light sensors to adapt the display's white balance to the
surrounding ambient light.[32][33] Although the iPhone X does not
feature the same "ProMotion" technology used in the displays of the
second-generation iPad Pro, where the display delivers a refresh rate of 120Hz,
it does sample touch input at 120Hz.[34] OLED screen technology has
a known negative trend of "burn-in" effects, in which particular
elements consistently on the screen for long periods of time leave a faint
trace even after new images appear. Apple acknowledged that its OLED screens
were not excluded from this issue, writing in a support document that
"This is also expected behavior".[35][36] Greg Joswiak,
Apple's vice president of product marketing, told Tom's Guide that the
OLED panels Apple used in the iPhone X had been engineered to avoid the
"oversaturation" of colors that using OLED panels typically results
in, having made color adjustments and "subpixel"-level refinements
for crisp lines and round corners.[37][38] For out-of-warranty
servicing for damages not relating to manufacturing defects, screen repairs of
iPhone X cost US$279, while other damage repairs cost US$549.[39][40]
The iPhone X has two color options;
silver and space gray.[32] The sides of the phone are composed of
surgical-grade stainless steel to improve durability, and the front and back
are made of glass. The design is intended to be IP67 water and dust resistant.[32][41]
The iPhone X contains Apple's A11
Bionic system-on-chip, also used in the iPhone 8 and 8 Plus, which is a
six-core processor with two cores optimized for performance (25% faster than
the A10 Fusion processor), along with four cores optimized for efficiency (70%
faster than the previous generation).[42] It also features the first
Apple-designed graphics processing unit[43][44] and a Neural Engine,
which powers an artificial intelligence accelerator.[45][46]
Face ID replaces the Touch ID
authentication system. The facial recognition sensor consists of two parts: a
"Romeo" module that projects more than 30,000 infrared dots onto the
user's face, and a "Juliet" module that reads the pattern.[47]
The pattern is sent to the Secure Enclave in the A11 Bionic chip to confirm a
match with the phone owner's face.[48][49] By default, the system
will not work with eyes closed, in an effort to prevent unauthorized access but
this requirement can be disabled in settings.[48]
The iPhone X has two cameras on the
rear. One is a 12-megapixel wide-angle camera with f/1.8 aperture, with support
for face detection, high dynamic range and optical image stabilization. It is
capable of capturing 4K video at 24, 30 or 60 frames per second, or 1080p video
at 30, 60, 120 or 240 frames per second.[50] A secondary, telephoto
lens features 2× optical zoom and 10× digital zoom with an aperture of f/2.4
and optical image stabilization.[51] A Portrait Mode is capable of
producing photos with specific depth-of-field and lighting effects.[52]
It also has a quad-LED True Tone flash with 2× better light uniformity.[53]
On the front of the phone, a 7-megapixel
TrueDepth camera has an f/2.2 aperture,[51] and features face
detection and HDR. It can capture 1080p video at 30 frames per second, 720p
video at 240 frames per second,[50] and exclusively allows for the
use of Animoji; animated emojis placed on top of the user's face that
intelligently react to the user's facial expressions.[54][55]
iPhone X also supports Qi-standard
wireless charging.[32] In tests conducted by MacRumors, the
iPhone X's charging speed varies significantly depending on what types of cables,
powerbanks, adapters, or wireless chargers are used.[56]
Software
Due to its different screen layout,
iOS developers are required to update their apps to make full use of the
additional screen real estate. Such changes include rounded corners, sensor
"notch" at the top of the screen, and an indicator area at the bottom
for accessing the home screen. Apple published a "Human Interface
Guidelines" document to explain areas of focus, and discouraged developers
from attempting to mask or call special attention to any of the new changes.
Additionally, text within the app needs to be configured to properly reference
Face ID rather than Touch ID where the authentication technology is used on
iPhone X.[57] In anticipation of the release of the phone, most major
apps were quickly updated to support the new changes brought by iPhone X,[58]
though the required changes did cause delayed app updates for some major apps.[59][60][61]
The traditional home button, found
on all previous devices in the iPhone lineup, has been removed entirely,
replaced by touch-based gestures. To wake up the device, users can tap the
display or use the side button; to access the home screen, users must swipe up
from the bottom of the display; and to access the multitasking window, users
must swipe up similarly to the method of accessing the home screen, but stop
while the finger is in the middle of the screen, causing an app carousel to
appear.[62][63]
Reception
General
reviews
iPhone X's rear camera received an
overall rating of 97 from DxOMark, a camera testing company, short of the
highest score of 99, awarded to Samsung's Galaxy S9+ smartphone. Google's Pixel
2 received a rating of 98.[64][65] Consumer Reports, a non-profit,
independent organization aiming to write impartial reviews of consumer
products, ranked iPhone X below iPhone 8 and iPhone 8 Plus, as well as below
Samsung's Galaxy S8, S8+ and Note 8, due to less durability and shorter battery
life, although it praised the X's camera as "the highest-rated smartphone
camera" it had ever tested.[66][67]
Nilay Patel of The Verge
praised the display, calling it "polished and tight and clean" and
"bright and colorful". He criticized the repeated lack of a headphone
jack, the device's fragility despite Apple's claims of durability, and the
sensor notch, calling it "ugly". Patel highlighted the fact that apps
required updates to fit the new screen, writing that not all popular apps had
received updates by the time of the review, resulting in some apps with
"huge black borders" resembling iPhone 8. He especially criticized
the positioning of the sensor notch while holding the phone in landscape mode,
causing the notch to go "from being a somewhat forgettable element in the
top status bar to a giant interruption on the side of the screen". The
cameras were given positive feedback for maintaining detail in low-light. Patel
particularly praised Animoji, calling it "probably the single best feature
on the iPhone X", writing that "they just work, and they work
incredibly well". Finally, he wrote that Face ID was the whole foundation
of iPhone X, and stated that it "generally works great", though
acknowledging the occasional misstep, in which users must "actively move
the phone closer to your face to compensate". He specifically criticized
the limited range of Face ID, with authentication only working when holding the
phone 25–50 centimeters away from the face.[68]
Chris Velazco of Engadget
also praised the display, writing that, in his experience, the sensor
"notch" goes from being "weird at first" to not being
noticeable due to action in videos usually happening in the center. The build
quality was given particular acclaim, being called "a beautifully made
device" with a construction that "seamlessly" connects the front
and back glass with the stainless-steel frame. Velazco noted that the new
gesture-based interaction takes time getting used to, particularly the Control
Center being moved from the bottom to the top right of the display. The camera,
processor performance, and battery life were also given positive thoughts.[69]
In a heavily negative review, Dennis
Green of Business Insider significantly criticized the impossible
one-handed use of iPhone X, writing that the new gestures to use the phone,
such as swiping from the top down to access notifications and the Control
Center, did not work when using the phone with only one hand due to not being
able to reach the top.[70] His review sparked outrage among Twitter
users, many of whom used condescending tones, which Green reasoned as "I
don't know whether the anger was directed toward me out of loyalty to Apple or
to justify their own choice to spend $1,000 on a phone. It was obvious that
much of the criticism came from people who had never used the phone".[71]
Macworld's Roman Loyola praised the Face ID authentication system,
writing that the setup process was "easy" and that its system
integration was "more seamless" than the Touch ID fingerprint
authentication of the past. That said, Loyola did note the "half-second"
slower unlocking time than Touch ID as well as needing to look directly at the
screen, making it impossible to unlock with the phone next to the user on a
desk.[72]
Face
ID security and privacy concerns
Face ID has raised concerns
regarding the possibility of law enforcement accessing an individual's phone by
pointing the device at the user's face.[73] United States Senator Al
Franken asked Apple to provide more information on the security and privacy of
Face ID a day after the announcement,[74] with Apple responding by
highlighting the recent publication of a security white paper and knowledge
base detailing answers.[75][76]
Inconsistent results have been shown
when testing Face ID on identical twins, with some tests showing the system
managing to separate the two,[77] while other tests have failed.[78]
However, despite Apple's promise of
increased security of Face ID compared to the Touch ID fingerprint
authentication system,[79] there have been multiple media reports
indicating otherwise. The Verge noted that courts in the United States
have granted different Fifth Amendment rights in the United States Constitution
to biometric unlocking systems as opposed to keycodes. Keycodes are considered
"testimonial" evidence based on the contents of users' thoughts,
whereas fingerprints are considered physical evidence, with some suspects
having been ordered to unlock their phones via fingerprint.[80] Many
attempts to break through Face ID with sophisticated masks have been attempted,
though most have failed.[81] A week after iPhone X was released,
Vietnamese security firm Bkav announced in a blog post that it had successfully
created a $150 mask that tricked Face ID, though WIRED noted that Bkav's
technique was more of a "proof-of-concept" rather than active
exploitation risk, with the technique requiring a detailed measurement or
digital scan of the iPhone owner's face, putting the real risk of danger only
to targets of espionage and world leaders.[82][83]
Additionally, Reuters
reported in early November 2017 that Apple would share certain facial data on
users with third-party app developers for more precise selfie filters and for
fictional game characters to mirror real-world user facial expressions.
Although developers are required to seek customer permission, are not allowed
to sell the data to others nor create profiles on users nor use the data for
advertising, and are limited to a more "rough map" rather than full
capabilities, they still get access to over 50 kinds of facial expressions. The
American Civil Liberties Union (ACLU) and the Center for Democracy and
Technology raised privacy questions about Apple's enforcement of the privacy
restrictions connected to third-party access, with Apple maintaining that its
App Store review processes were effective safeguards. The "rough map"
of facial data third-parties can access is also not enough to unlock the
device, according to Reuters. However, the overall idea of letting
developers access sensitive facial information was still not satisfactorily
handled, according to Jay Stanley, a senior policy analyst with the ACLU, with
Stanley telling Reuters that "the privacy issues around of the use
of very sophisticated facial recognition technology for unlocking the phone
have been overblown. … The real privacy issues have to do with the access by
third-party developers".[84][85]
Sensor
housing controversy
Much of the debate about the iPhone
X has revolved around the design of the sensor housing, dubbed
"notch" by the media, at the top of the display. The Outline
described it as "a visually disgusting element",[86] and The
Verge posted a report focusing on public criticism and people mocking
Apple's "odd design choice",[87] but not every reviewer
was equally negative in their opinions. Third-party iOS developers interviewed
by Ars Technica said that, despite the work of restructuring design
elements in their apps, the notch did not cause any problems, with some even
arguing that the notch was a good push to simplify their designs.[88]
Just two weeks after iPhone X's release, Apple approved a "notch
remover" app through the App Store, that places black bars across the top
of the home screen to make the notch visually disappear. The approval was done
despite the company's user interface guidelines discouraging developers from
specifically masking the design.[89] It should be noted however that
iPhone X was not the first device with a notch - both the Essential Phone and
Sharp Aquos S2 were announced before it and had a display notch - but iPhone X
arguably popularized it.[90][91]
Issues
Early
activation issues
In November 2017, early adopters of
the new phone reported that they were experiencing activation issues on certain
cellular carriers, most notably AT&T. AT&T announced within hours that
the issue had been fixed on their end, and a spokesperson for the Verizon
carrier told the media none of its customers were affected despite some reports
of problems.[92][93]
Cold
weather issues
In November 2017, iPhone X users
reported on Reddit that the device's screen would become unresponsive after
experiencing rapid temperature drops.[94][95] Apple released the iOS
11.1.2 update on November 16, 2017, fixing the issue.[96][97]
Forbes contributor Gordon Kelly
reported in March 2018 that over 1,000 users experienced problems using camera
flash in cold weather, with the problem still persisting as of iOS 11.3 beta 1.[98]
Cellular
modem differences
Apple has been engaged in a legal
battle with Qualcomm over allegedly anti-competitive practices and has been
dual-sourcing cellular modem chips to reduce reliance on the semiconductor
manufacturer. Starting with iPhone 7 in 2016, Apple has used about half
Qualcomm modem chips and half Intel.[99][100] Professional
measurement tests performed by wireless signal testing firm Cellular
Insights indicated that, as in the previous-gen iPhone 7, Qualcomm's chips
outperform Intel's in LTE download speeds, up to 67% faster in very weak signal
conditions,[101][102] resulting in some sources recommending the
purchase of an unlocked iPhone X or one bought through cellular carrier
Verizon, in order to get the models featuring the faster Qualcomm modem.[100]
Additionally, CNET reported in September 2017 that the new iPhone
models, including X, 8 and 8 Plus, do not have the ability to connect to the
next-generation of wireless LTE data connection, despite 10 new Android
devices, including flagships from main smartphone competitor Samsung, all
having the capability to do so. While Apple's new smartphones have support for
"LTE Advanced", with a theoretical peak speed of 500 megabits per
second, the Android models have the ability to connect to "Gigabit
LTE", allowing theoretical speeds up to 1 gigabit per second, doubling
Apple's speed.[103]
NFC
Problems
After releasing the iPhone X in
Japan and China, users who had Suica payment for transit and in China the
Express Transit Cards had issues with NFC reading properly. The iPhone 8 did
not see this similar problem and only affected the iPhone X models. April 2018,
Apple released a revision to the X, Rev B that included a vastly improved NFC
chip that solved the problem of NFC reader errors and double reads on transit
gates or store readers on a regular basis: on average 1 out of 3 NFC attempts
would error after initial reports. This affected users in America as well. [104]
