iPhone X Review

One week with the iPhone of the future – today.


• Superb resolution and rendering of fonts

• Blackest blacks and highest contrast

• Great color rendition when looking straight perpendicular at the display

• Noticeable shift to blue color tint when the phone is tilted out of perpendicular view by ~15°, most noticeable with bright or white backgrounds. I had a chance to look at a Samsung Galaxy S8 this week, which has a far more pronounced color shift problem, when not looking straight at the display.

• At the screen edges you can see a slight shift in hue, also most noticeable with bright backgrounds.

• True Tone sometimes feels a little too “warm“ to me, but I keep it enabled since otherwise everything is way too blue if you are inside especially with incandescent light. I have disabled Night Shift and use True Tone only.

• I had no problem to use the iPhone X with polarizing sun glasses, no color shift or drastically reduced brightness, no matter if the device is used in portrait or landscape orientation. This is a big improvement over the LCD displays that in portrait orientation were hard to read with such sun glasses.

• Bright backgrounds don’t suit the iPhone X screen well. Dark backgrounds make the slight problems with off-angle viewing almost unnoticeable, promote the great contrast the display has and black background lets the bezels and the notch completely disappear.

• Speaking of the notch, I don’t mind it, most of the time don’t even notice it, except when you switch to an app with bright background. I actually like having the time and status shown up there in the “ears”.


• It just works!

• Works in complete darkness

• Cool animation of the lock while FaceID is doing its magic

• Works with my polarizing sun glasses with attention awareness turned on

• Works for me even while lying in bed

• Haven’t had to enter my code because of failed FaceID attempt once

• My brother wasn’t able to unlock my iPhone X with FaceID. Although many people confuse me with him, FaceID is able to distinguish us.

• Using FaceID in apps that did already support TouchID and to fill passwords from iCloud Keychain works frictionless.

Design and Build Quality

• I have the silver version with the shiny stainless steel frame

• It’s just beautiful!

• Perfectly matches the aesthetics of the stainless steel Apple Watch

• Coming from a Plus sized iPhone, it feels nice to have a big screen in a much smaller device.

• The iPhone X has its heft without feeling heavy. It feels good in the hand. The glass back improves the grip, so that I am confident enough to use it without a case.

Ease of Use

• Using iPhone X feels like the original iPhone again, instead of sliding to unlock you now swipe up to unlock and you are good to go.

• No authentication interrupting you. With FaceID you have the benefit of security, without the hassle of a passcode.

• FaceID is slower than 2nd generation TouchID, but I never had the impression I was held off or had to wait for it.

• The animations for unlocking, multitasking, opening and closing apps are so smooth and feel so natural, it’s a fun to use this phone with its new gesture based UI, even just going back and forth between apps or to the Homescreen.

• I don’t miss the Home Button!

• Swiping up to “uncover”, go home or activate app switcher feels natural

• Activating Control Center from the top right takes time to get used to and is hard to do one handed.

• I have tested Reachability and turned it off again, the UI feels weird if you combine Reachability and activating Control Center or the Cover Sheet for notifications and widgets, too much sliding going on.

• Switching apps swiping horizontally in the Home Indicator area is nice and easy, sometimes though an app you would expect to the right is no longer there but seems to be resorted in the stack and you must swipe right to find it on the left side.

• To reliably activate the multitasking AppSwitcher move your finger to the right while swiping up from the Home Indicator.

• Tap to the wake is another seemingly small addition that feels overdue when going back to others iPhones that don’t have it.


• I am not the selfie guy, but having portrait mode on the front camera is a great addition.

• Portrait Lighting is officially still in beta, but the studio light setting looked good in my tests, better than default natural light. Results for the Stage Light effect vary, but often look not good enough.

• Wide angle camera 28 mm (equivalent focal length, real 4 mm, 7x crop), same as in 7, 7 Plus, for comparison the Google Pixel has a 26 mm equivalent lens with a real focal length of 4,67 mm (5,57x crop) which means the Pixel has over 50% more sensor area than the iPhone 7/8/X wide camera

• Telefocus camera lens 52 mm (equivalent, real 6 mm, 8,67x crop), slightly wider than 7 Plus telephoto lens, Sensor now with optical image stabilization, but even smaller than in the 7 Plus which had 56 mm (6,6 mm, 8,48x crop)

• Indoors the iPhone most of the time does not use the telephoto camera, but does digital zoom, unless it’s really bright.

• Given the small sensors used in the iPhone cameras – compared to the Google Pixel – it’s surprising that iPhone keeps up so well in image quality. Apple obviously has perfected image processing algorithms with its custom ISP.

• In a direct comparison of the iPhone 7 Plus camera with the Google Pixel, that I did last year, the iPhone had no chance matching the Pixel’s resolution and details, which is no surprise given the difference in sensor size. The iPhone had slightly better color rendition and overall exposure. If you are not pixel peeping, the iPhone images often look a little more pleasing and therefore often win in “real world” comparisons.

Battery Life and Charging

• Still very early to really judge, but battery life seems at least on par with my iPhone 7 Plus.

• Without really timing it, charging it with a 10 W iPad charger felt quicker than with older iPhones.

• Charging with the Qi inductive charger integrated in the stand of my HP S240uj display at the office worked without problems.

Setup Process

• This was the first time I used the Quick Start feature that lets you transfer settings from another iOS device by just holding it close to the new iPhone.

• After the settings are transferred it is just a few steps until your data is restored from an iCloud backup.

• Having to do an over the air update to iOS 11.1 during this process was a new experience to me.

• This was the first time I didn’t restore a new iPhone from an iTunes backup, so I was a little nervous, but the process was smooth and everything went well. Waiting for all apps and data to be downloaded took longer than restoring from iTunes, but succeeded flawlessly. Even activity data that seemed to be missing at first reappeared after a while.

• Important advice for Apple Watch users: Unpair your watch on the old phone before setting up the new one. This will backup all data and once the new phone has finished initial setup it will automatically detect your watch, let you pair it and restore the watch from the backup.

Other Impressions

• Animoji are fun and it’s stunning how detailed the facial animations are. Don’t show them to your kids, if you want your phone back anytime soon. Interesting to see that Animoji do not include your tongue, though.

• After just a little more than a day with the iPhone X the screens of older iPhones already feel letterboxed and strangely square.

• I always want to swipe up now, being forced to use the Home Button on older iPhones feels cumbersome.

• Animated WiFi signal strength indicator and the animated plane in the status bar “ears” when switching Airplane Mode are cute little details.

• iPhones always lacked in their ability to cling to a weak cellular signal compared to the simple feature phones that I used in the early 2000s. iPhone X pleasantly surprised me. It stays much better connected to cellular during my daily commute train ride than the iPhone 7 Plus that I used until a week ago.


It’s fair to say I love this phone. It’s a gorgeous well built device. Impressive FaceID, the beautiful, big screen and all the other improvements, even in details, make this the greatest Apple product I have owned so far.

Stay tuned for more, I will update this review after I had more time with the device. Especially more details on the camera and image quality are still to come.
