iPhone XR showcases best battery life of all iPhones, our testing confirms

The new 6.1" iPhone XR has a ho-hum display resolution of 828 x 1792 pixels, returning 326 pixels per inch density, or just enough to be called "Liquid Retina." This is low for today's standards when even midrangers ship with 1080p Full HD screens. The flagship Huawei Mate 20, for instance, has a display with "average" FHD+ resolution which still sports much higher pixel density than the iPhone XR, on a larger screen. 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 just 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.

The battery in the 6.5" iPhone XS Max is of larger capacity compared to the XR, and 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" 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. 

In our iPhone XR review we did put Apple's "best battery life" claims to the test and it indeed lasted the exceptional 11+ hours of screen-on time during our demanding benchmark grind. That's more than Apple's previous record-holder the 8 Plus indeed. The circuit-breakers from iFixit recently disassembled the iPhone XR and found that its battery is actually thicker and with a larger capacity than the one in the 8 Plus despite that it looks marginally smaller.

Since the phone's standby times are also pretty good, we found it able to endure up to two days with moderate usage which makes the iPhone XR the most impressive handset in terms of battery life Apple has ever made, and the much-maligned screen resolution is the likely culprit behind that record. Charging speeds are a whole different story, though, unless you get an extra fast charger.

Battery life (hours) Higher is better
Apple iPhone XR 11h 1 min (Excellent)
Apple iPhone 8 Plus 10h 35 min (Excellent)
Apple iPhone XS Max 9h 34 min (Excellent)
Apple iPhone XS 8h 37 min (Excellent)
Samsung Galaxy S9 7h 23 min (Good)
LG V40 ThinQ 6h 21 min (Average)
Charging time (minutes) Lower is better
Apple iPhone XR 192
Apple iPhone 8 Plus 178
Apple iPhone XS Max 209
Apple iPhone XS 185
Samsung Galaxy S9 107
LG V40 ThinQ 109

Yep. XS Max last slightly longer than XR, while Mate 20 Pro and Note 9 beat both of them. (even OP6T beat XR :-| )

Don't really pay that much attention to youtube tests though. They are far far off from real world usage. I see people on XDA and OnePlus forums reporting 8-9 hours of Screen On Time on 6T over 2 days of usage. That is absolutely amazing. And if one decides to end it in a day, SOT is crossing 10 hours easily. From what i have seen GSMArena battery tests are the most realistic of all but yet sometimes even their results are off a bit.

No they are not. They may be far off from your usage. So you really gonna claim. Thay no one web browses for at least an hour? Play video games foe at least an hour? Watch movies for at least an hour? And be on social media for at least an hkir? Because most tests I see is exactly what they are showing? But that's far far off? Dude? Really?

Your "normalize" extrapolation is total nonsense. The size of the battery is what it is. That's like saying your car would have a range of 5,000 miles if it had a 200 gallon fuel tank. Well it doesn't and it can't.

well, its just an speculation for those who are interest to know , btw the real battery life result are shown above as well. consider mate 20 pro run at not native resolution (33% lesser ) and both iphone & mate are on 7nm processor, mate 20 pro with a much larger battery(32% larger) only last 5% longer than iphone xs max. i would expect much longer battery life for mate20pro. the comparsion with the rest are not telling a clear picture as their soc are on different manufacturing process.

You took wrong YouTube test results. Phonebuff are the best ones. Close to real life, not like stupid benchmarks running in circles.https://youtu.be/RF6-eLoNwZQ

The two people I know that have the Xr are both praising its battery life. One of them had an S7 Edge and was complaining about poor battery life and a significant slowdown of the phone in general. Edit: should have been a reply to #4.

Add me to the list. I have been very pleased with the Xr's battery life, especially coming from a 7.

Reposting as I was moderated without violating any forum rules. If you don't use it, eks R does great. Otherwise as most videos have shown, with typical stress this phone is average at best.https://youtu.be/LkiniAkBOyU

Interesting, from all those phones, iPhones have the smallest batteries - yet the lasted about the same as the biggest battery phones and killed Samsung devices.

Yes and they dont have the feature set if the phone with big batteries either. That iPhone isnt pushing 6GB of ram, it isnt pushing a 6.4" 1080p or QHD display. It doesnt have as many background task either. I have a question for you. When you make posts such as this, do you consider all factors of a computer? Because you seem to turn a blind eye to this facts. Because you Apple fans never consider that most Android phones, especially the S and Note have considerable more software on them. The fact is since the the iPhone and most Android phone actually have less features vs the S and Note, their batteries should actually last longer than they do and yet they dont. Example? A car with a smaller engine and a smaller gast tank, still manages to get better gas mileage than cars with larger engines and bigger tanks. Need an example? And old car called the Geo Metro, gets 50 miles to a single gallon, while on average most 6 or 8 cylinder engine cars get only 30 highway on average. My SUV has an engine that actually builds better mileage as it drives. I have a 22 gallon tank with a V6 and I have gotten 550 miles from a single tank if I stay locked at not more than 70mph, which means if I drove 65, I would get over 600 miles. You need to open your eyes and consider all factors. I take all battery test with a grain of salt, because even thought theybrey to show you some idea, many dont use their phones the same.

What are you stupid? iPhones may not have some features that androids do, but androids don’t have features that iPhones do! Androids also don’t have features other androids do either. You can customize your icons on your Samsung, I can customize Siri language and dialect (bixby doesn’t have that), you have higher resolution, I have forcetouch. You have more ram, my phone is faster. You have google services - so do iPhones! Your has bigger battery, mine lasts just as long which much smaller. You have MST, I have iMessage Apple cash. It really comes down to feature set that fits you best. You’rean ignorant nation if you think the phone you like is best for me. I used Samsun notes for the past few years - and my experience is better using an iPhone. It’s not about specs it’s how you enjoy your phone. I can have more fun in my zippy little car than you in your oversized minivan with 15 cup holders. And your car analogy is stupid. Because iPhones are faster and snappier than your Samsung especially after 6 months of use. You can tell me that I don’t know how to maintain my phone - with iPhone - I don’t have to - and that’s a feature worth more than your widgets!!!! Ok pumkin?

That's why he said "most", that link is just one of few bad battery life testing you can find on youtube. He cut too many part of it and could easily cheat between it, while most tester show uncut footage (with speedup) and readable stopwatch apps for timer.

Got it. They are cheating if the results are not in your favor.

PA tests are cheating. Because noniOhone on this planet that is being used last more than 6 hours. No matter what chip it has or what size battery. Why? Because the A series chips are poorly optimized and you ca see this in the test. Example, the iPhone is the only phone that loses 50% battery with justb2 hours of web browsing. The iPhone is the only phone I history whereon a degraded battery, the phone shuts off with 20% battery remaining.

42. strategic_developer

Posts: 1627; Member since: Jul 17, 2018

They are cheating if the results are anything above what the average tests are showing. No iPhone model can exceed 6 hours if it's actually being used foe ANYTHING. It is a proven fact!

54. worldpeace

And where's your argument? That particular test result are way different from most other result on youtube, and it's the only test (that I know) that cut the footage. There must be something wrong with that test. You must be really dumb to defend one particular test that's obviously rigged in some way.
