CR's Final iPhone X Test Results: Top-Scoring Camera and Display But Also
Some Flaws
Apple shoppers face a tough choice between this phone and the iPhone 8
The iPhone X is an innovative device with a fantastic camera and beautiful
display, but other phones are tougher and can operate longer on a charge.
Those are among the conclusions we've reached after completing testing on
Apple's new flagship model, which starts at $1,000 for the 64-gigabyte
version.
Overall, the iPhone X-as in 10, not the letter that follows W-easily made
Consumer Reports' recommended list and broke into the extremely tight list
of top 10 rated phones, where all the devices are separated by only two
points on our 100-point scale.

It was edged out by Apple's less-expensive iPhone 8, starting at $700, and 8
Plus, starting at $800, which both proved hardier in a test designed to
reproduce the drops and fumbles that can cause cracked screens and other
damage.
"If not for the damage in that durability test, the iPhone X would have come
in ahead of the iPhone 8 and 8 Plus," says Richard Fisco, head of smartphone
testing at CR.
Given how close the scores of all the phones in our top 10 are, it's not
really a question of which phone is best but which is the best fit for you.
More on Smartphones 
If you're choosing among the new crop of iPhones, one of the most obvious
differences is the lack of a Home button on the iPhone X and the advent of
Face ID for unlocking the phone (more on that below).
Additionally, the iPhone X has the biggest screen of the three-5.8 inches,
measured diagonally, compared with 5.5 inches for the iPhone 8 Plus and 4.7
inches for the 8. But that expansive display comes in a tight package: The
iPhone X is just a smidge taller than the iPhone 8 at 5.6 inches, and more
than a half-inch shorter than the iPhone 8 Plus.
Here's a closer look at our test results and how the iPhone X compares with
other top-rated phones on the market.
The iPhone X's Strengths
 
The iPhone X's OLED display excelled in CR's color accuracy, brightness, and
vibrancy tests.
Beautiful Display
The iPhone X features Apple's first OLED phone screen. The technology,
already used by smartphone manufacturers such as LG and Samsung and found in
some high-end TVs, can produce very deep black tones and unlimited viewing
angles. (That means the image doesn't noticeably degrade when you view the
screen from the side.)
Our testers gave the phone's display excellent marks, pointing to its
overall brightness and vibrant colors, along with the deep black levels.
We think that Apple shoppers who put the iPhone X side by side with the
iPhone 8 and 8 Plus will notice a significant difference, although these
phones have very good screens as well.
Outstanding Cameras
The rear camera on the iPhone X is among the best we've ever seen. In fact,
if you combine the performance scores for stills and video, this is the
highest-rated smartphone camera Consumer Reports has tested.
Like the 7 Plus and 8 Plus, the iPhone X has a second, 2X zoom camera on the
back of the phone. But unlike those other iPhones, both of the iPhone X's
backside cameras have optical image stabilization, which steadies the lenses
to offset the effects of shaky hands. (The 7 Plus and 8 Plus have that
feature on only one camera lens.)
This setup produced impressive results when testers compared photos using
the zoom to those shot using the zoom lenses of earlier iPhone Plus models.
Stills taken with the iPhone X were sharp, with excellent color
reproduction, and video was very sharp as well.
Convenient Face ID
Much has been made of Apple's decision to do away with the Home button on
the iPhone X. That opened up screen real estate, but when the Home button
disappeared, the embedded fingerprint sensor went with it, and Apple now
relies upon a new biometric feature for authenticating users. Called Face
ID, the technology maps your features and lets you unlock the phone simply
by taking a look at the screen. (You can also type in a PIN.)
We found the setup and unlocking process to be both quick and easy. The
technology worked when we held the phone at all but the most severe angles
and did not falter when used by testers with a wide range of skin tones,
even when they put on reading glasses. You need to look directly at the
screen to prompt it to unlock, making it less likely that you'll unlock the
device inadvertently. 
The removal of the Home button requires you to learn a series of new swipe
and button commands to operate the phone. This takes a little getting used
to. But our testers picked up on the new gestures quickly and were satisfied
with the phone's overall usability.
The iPhone X's Shortcomings
 
The iPhone X suffered damage in the tumbler, which drops each phone
repeatedly from about 2.5 feet.
Broken Glass
In our initial drop test, the iPhone X performed just fine. It survived four
falls onto a concrete surface from a height of 5 feet. For that quick test,
we used our custom-designed Drop Tower and let the phone fall on its front,
back, and two different corners.
However, iPhone X phones didn't fare nearly as well when subjected to a more
intensive lab test in a tumbling machine. The tumbler is a rotating chamber
that repeatedly drops a phone from a height of about 2.5 feet. The phones
are checked for damage after 50 drops and then again after 100.
The goal of all that repetition is to expose the phone to impacts from a
wide variety of angles.
We tumbled three samples of the iPhone X. The first was fine after 50 drops,
but the glass on the back was significantly cracked after 100. The other two
phones ended up with malfunctioning displays after 50 drops. Though the
front glass didn't crack, several bright green bars stretched across the
screens from top to bottom.
The iPhone X isn't the first phone to fail our tumble test. For example, our
testers also reported broken displays and back panels when they tumbled
Samsung's nearly all-glass Galaxy S8 and S8+ phones.
In light of those results, we recommend that you protect any of these phones
in a case.
Responding to our findings, Apple affirmed the iPhone X's durability based
on the company's "rigorous real world testing" and said that the phone "is
made from the most durable glass ever in a smartphone."
Durability is something to think about if you're considering a purchase of
the iPhone X. The phone isn't just expensive to buy; it's also unusually
pricey to repair. For example, the Apple Store will charge you $279 to fix
the display and $549 to fix any other part of the phone, including its glass
back. (This could make it worthwhile for some consumers to shell out for
AppleCare+ coverage, which costs $199.)
Tumble tests don't get a lot of weight when we calculate a phone's Overall
Score. However, these results combined with the iPhone X's comparatively low
battery-life showing (see below) did knock the phone down a few spots in our
rankings, says Fisco, who leads CR's phone testing program.
On the flip side, the iPhone X aced our water-resistance testing, surviving
for 30 minutes at a depth of about 3 feet, just as Apple promises in its
specs. The phone was examined right afterward, as well as one, two, and
three days later, and continued to work.
This is consistent with the results for other recent Apple phones, including
the 7- and 8-series iPhones, which also did well in our water-immersion
tests. 
Short Battery Life
The iPhone X's battery life hurt the phone's Overall Score in Consumer
Reports testing.
To find out exactly how long a phone's battery can go, Consumer Reports uses
a robotic finger programmed to put the phone through a range of tasks
designed to simulate a consumer's average day.
The robot browses the internet, takes pictures, uses GPS navigation, and, of
course, makes phone calls. We run all smartphone battery tests with the
display set to 100 percent brightness. If you use any phone's auto, or
adaptive, brightness, the battery should last longer. 
In our testing, the iPhone X's battery lasted 19.5 hours. That's just ahead
of the 19 hours logged by the iPhone 8 and the considerably smaller iPhone
SE but below the 21 hours recorded by the 8 Plus-and it's far less than the
26 hours that Samsung's S8 and S8+ delivered. (Some other smartphones in our
ratings run even longer on a charge.)
While for many people 19.5 hours is enough to get them through the day, it's
still shorter than the majority of the 38 smartphones we recommend.
According to Apple, the iPhone X's A11 Bionic chip is designed to manage the
device's power supply intelligently, balancing the demands for speed and
energy in a way that permits you to complete the tasks you perform most
often-think texting or web browsing-with optimal efficiency.
When you combine that with the model's custom battery design, the company
says, the iPhone X should last "up to 2 hours longer between charges than
the iPhone 7." In our tests, the iPhone 7's battery lasted 18.5 hours.
Which iPhone to Buy?
If you're looking for a new iPhone, is the X worth the $1,000 and up that
Apple is charging? That depends on your preferences.
A lot of people would argue that the iPhone X represents the future of
smartphones. It boasts the best overall camera results in CR's testing and
one of the best displays we've ever seen on a phone. And while you don't get
the familiar Home button, you pick up a decent amount of screen space in a
phone that's significantly smaller than the 7 Plus and 8 Plus. It's easier
to hold and use, not to mention lighter to carry.
And Face ID works very effectively. The phone seems to unlock as soon as you
pick it up and even think about making a call. Its gesture system takes some
getting used to, but it's not overly cumbersome or difficult to use.
Taken as a complete package, this phone ranked a bit lower than Samsung's
S8, S8+, and Note8, mainly because of their superior battery life. But many
longtime iPhone users aren't interested in switching to Android, so the real
question for them is whether to save a few bucks-or, actually, a couple
hundred-and go with an iPhone 8 or 8 Plus instead.
These iPhones are more resistant to breaking, and they have the familiar
Home button, which means you don't have to spend time learning a new system
of swipes and button clicks. Because all these phones are top performers,
the choice is ultimately a matter of personal priorities.
Here's another idea: If you want to save even more money, the iPhone 7 and 7
Plus remain viable options. They look pretty much the same as the 8 and 8
Plus and offer many of the same features. And they'll cost you just $550 and
$670, respectively. 
If you're still on the fence, this is one of those times where it pays to
try before you buy. Play with all of these phones in the store, paying
attention to how much the gorgeous iPhone X display means to you and how you
feel about learning new gestures-and then considering how often you've
dropped previous gadgets on the sidewalk.
