Display Measurement

The display of the iPhone XR is likely its most discussed hardware feature, simply because Apple chose to diverge from the OLED screens on the XS models and instead use a more traditional LCD screen. While that in itself shouldn’t have caused too much talk, Apple also made the interesting choice to go with a relatively low-resolution 1792 x 828 panel. This represents a lower pixel density than what we would expect out of a sizable 6.1” (diagonal) display.

The following pictures are some close-up shots of the iPhone XR next to the iPhone XS – unaltered at the full resolution of my DLSR. The pictures are best compared when you open up the full resolution images.

Cropping 1:1 areas with the same icons on both phones, we have almost the same feature sizes so it allows for a good direct comparison.

When you have both phones side-by-side, it very quickly becomes evident that the iPhone XR isn’t able to compete with the sharpness of the XS models. While the LCD panel does allows for better defined right-angle edges, its definition on anything else is clearly lower than that of the iPhone XS. The most evident difference of this is on text such as the clock icon’s numbers (the icon labels aren’t a good comparison because of different font sizes); here the XS panel is just very much ahead in practical spatial resolution.

In every-day use-cases where you would browse your phone at an arm-length away, these differences are hard to notice, and it should not cause any issues for the majority of users. Though if you do like to hold your phone close to your face – as I like to do late at night in bed – then you might find it hard to get used to the less defined and blurrier text of the iPhone XR. I think the main issue I have with the iPhone XR’s display is that it’s actually somewhat of a downgrade from the iPhone 8 Plus in terms of resolution – while I understand that Apple wanted to use a more affordable panel, I do think it would have prudent to at least match the 401ppi pixel density of an iPhone 8 Plus.

While the resolution of the iPhone XR screen is a debatable topic and is something that should be decided by users by experiencing it themselves, the other aspects of the LCD panel are things that Apple definitely got right: The screen offers absolutely excellent viewing angles, even when viewed from off-axis. This is a simple characteristic that many vendors often get wrong when choosing an LCD display panel, yet Apple always manages to be on-point in this regard.

We move on to the display calibration and fundamental display measurements of the XR screen. As always, we thank X-Rite and SpecraCal, as our measurements are performed with an X-Rite i1Pro 2 spectrophotometer, with the exception of black levels which are measured with an i1Display Pro colorimeter. Data is collected and examined using SpectraCal's CalMAN software.

At our standard 200 nits measurement point, the iPhone XR is absolutely spot-on in terms of greyscale accuracy, even though it’s just ever so slightly above a D65 white target. The colour temperature seems to vary with brightness, as at peak brightness the phone goes down to a 6500K average CCT. It’s to be noted at these levels the display has weak greens – I personally can’t perceive this just looking at the phone, but holding it side-by-side next to the XS makes it more apparent. Nevertheless, it’s not an issue in my view.

Peak brightness goes up to 694 nits on my unit – about 40 nits higher than what I’ve been able to measure on the XS and XS Max. The greyscale calibration here only seems to slightly miss one aspect: the gamma is just a bit too high, with an average of 2.28, and this seems to be skewed at higher brightness levels, where it can have a gamma of up to 2.4. We can see this in the greyscale comparison image, as we see some of the tones being slightly darker than the reference target.

Apple has full support for colour management and the display as well as the OS is able to concurrently display sRGB content alongside wider gamut Display P3 D65 images. Saturation level accuracy in both gamuts is fantastic, coming in at DeltaE2000 of 1.24 and 1.17 for sRGB and P3 targets respectively. While the results are not quite as industry-leading as on the XS, they are both great results and you’d be very hard to perceive the differences.

The Gretag MacBeth collection of commonly found color tones again showcases some good results, with a dE2000 of 1.47. The comparison image only shows a slight difference in the luminance of the tones, something that can be attributed to the higher gamma of the screen.

Overall, the iPhone XR display is a very high quality screen when it comes to its fundamentals such as brightness, contrast (for an LCD) as well as excellent viewing angles. Apple’s colour calibration, while not quite matching that of its XS siblings, is still beyond what we usually find in other smartphones and should represent absolutely no issue. And the slightly higher gamma should not be something that it perceivable in every-day use-cases.

The resolution of the screen is actually my only real gripe about the display, and I do think that Apple was a bit too conservative in this regard. I use my phones a lot at night in bed where I have the screen closer to me – and this is one case where I would prefer a higher resolution. Again this is a subjective view on the topic and you’d best evaluate it yourself in person – but even though all other aspects of the XR’s screen are excellent, it does feel like a compromise for the phone.

    I don’t think 3dmark slingshot extreme is a good benchmark for iOS platform. First the cpu usage is too high even in the graphics test. Second the gpu vertex usage is nearly the half in the graphic test. However there is no issue in the slingshot OpenGL es 3.0 edition. It is too old and need to update. By the way, there are new GPU benchmark suits building on metal 2 in iOS and Vulkan in android named snow forest benchmark and orbital flight benchmark. Reply

    Agree. 3Dmark has always been very odd on iOS, especially the physics test, and hasn't matched real world performance comparisons I've seen between Android and iOS games. Reply

    Is the black value when at the the min brightness correct?
    If so, and assuming the spectrometer is the same a usual, then is this the first time we've seen an LCD that has an imperceptible off pixel while the backlight is still on?

    The better battery life comes from the lower resolution.

    The less pixels you use , the less power you need.

    I come from an iphone 8 and now I have iphone xs max 256 gb, I find completely false the duration table with the common use that lasts twice as compared to the iPhone 8 (both have the health of the beater to 100%) Reply

    More battery, More life.

    Great to see Andrei taking over for the smartphone reviews, this was a good read man!

    I believe that is one of such a lot significant information for me. I’m happy studying your article. I read much about iPhone mobile tablets and batteries. I have read on some other website you should see that is also great information there.

    I’ve had my iPhone XR for quite a while now and still like it very much. I upgraded from a 6S and am amazed by the battery life! I've had iPhones since the first model and no other iPhone has come close to the XR in battery life!

    The LCD vs OLED issue doesn't bother me. The lower resolution is still a retina resolution, and with fewer pixels to push, it makes for more efficient use of the processor and is one of the reasons it gets better battery life.

    I miss 3D Touch but not as much as I expected. I used it mainly for turning the keyboard into a trackpad but a long press on the space bar performs the same function, and does that more accurately.

    The camera may not be nice as the dual unit found on the XS/XS Max but it is an OIS camera which, coming from a 6S, is a nice upgrade.

    Its audio output is in stereo (which was a nice surprise) and is quite a bit louder. I’m not thrilled about the lack of a standard phono jack but as a long time Apple user I’m used (though still not happy with) the way they change ports.

    It may cost less than the XS/XS Max, but it's a serious upgrade for me. To add to the deal, one of the colors the phone comes in is (PRODUCT)RED which is a rich shade of red and a nice break from the black, white and silver I’ve had in the past.

    While it's missing a bell here and a whistle there compared to the XS/XS Max, it works great and is a nice upgrade from the 6S.

    And just in case nobody noticed, Apple made a slightly thicker and heavier iPhone with a bigger battery and Hell didn’t freeze over!
