The XR has the best iPhone battery life ever, precisely because its display is not 'Super Retina'

The XR has the best iPhone battery life ever, precisely because its display is not 'Super Retina'
The new 6" iPhone XR has a ho-hum display resolution of 828x1792 pixels, returning 326 pixels per inch density, or just enough to be called "Liquid Retina." The 6" Huawei P20 Pro, for instance, has an "average" for today's standards 1080p display which still sports much higher pixel density than on the iPhone XR. Apple to apples, if you will.

Given that the pixel density of a mobile display is perhaps the biggest single culprit behind battery life differences, all other things being equal, that comparatively low screen resolution of the XR works to one undeniable advantage - the phone's battery life. Our own power efficiency comparison found out that the higher a phone display's resolution, the shorter the battery life when we average out their capacities.

Apple is listing official battery life stats in the form of "up to" 15 hours of Internet browsing and 16 hours of video-binging, which are very respectable numbers for any handset, not only Apple phones. Not only that, but Apple is so proud of what it achieved with the iPhone XR's battery life, that it cites the "lasts up to 1.5 hours longer than iPhone 8 Plus" tidbit everywhere, as this was its previous marathon runner to aspire to.

Granted, we don't know how big is the battery in the 6.5" iPhone XS Max compared to the XR, but it's probably larger, as Apple said it is the biggest ever in an iPhone. Still, the iPhone XR has better endurance stats than the XS Max with its bigger pack, and the XR's "low-res" 828p display is the reason for what turns out to be the best ever battery life on an iPhone, according to Apple's own specs sheets. We can't wait to put these claims to the test of our own battery benchmark grind.

I bet it is the biggest seller of the 3 also. Most consumers will not care about LCD vs OLED. I think more will like the different colors then care about having the OLED screen.

Probably the most boring flagship launch in the year 2018, just when I thought nothing could top the S9. Now Bring on the offensive Huawei.. and show the world you aren't even joking

I literally got into an argument with a coworker on this. There’s very few differences which most consumers aren’t going to want to pay an extra $250 for.

Man the XR would be insta-buy for me, but the bezels are killing it. Those are way too thick - disappointed so much.

You joking right, if it had a 1080p screen It will have been a very good phone. But at the res it’s at at 6.1 “ it’s a joke and is doa

What you’re describing no one cares about - it’s sharp! The only difference you see is numbers on paper. The screens come with force touch abilities - that’s is far more important than side by side comparison because that’s the only time you see any negligible difference.

I just wanna know the mAh count. I know Apple doesn’t release those this earlier in a product launch, but it is the make or break factor between the XS Max and the XR for me. I don’t care about OLED or over-the-top resolution, but I do care about battery life.

Hey kiko, what about those bezels on XR? Bothers me quite a lot. Honestly. But yeah I couldn’t care less whether is LCD or OLED or w/e. It’s sharp: I’m happy.

The bezels are noticeably bigger, definitely. But that price ain't half bad, considering Apple's pricing strategy.

Screen is HD+. Off course it would last more.

I have said that this year's not going to be one where I will get an iPhone but, if this one's battery is way better than 8's (I'm thinking 10-12h of usage) and has dual sim (I don't really need it, but I would like to have it), I might change my mind (a cheap Android device made me reconsider the way I can use the phone).

The biggest improvement is for Talk time but that's most likely because it uses a better modem. In the rest the improvements in battery use rage around 10-11% better on average than the 8 Plus which is no impressive at all. Anyway I'm sure Phone Arena's battery test will make the XR have a much "better" battery life than any phone on the market now(even better than midrage battery phones).
