HTC U Ultra battery life test result serves us a surprise


The HTC U Ultra is a stunning looker: with its shiny back, slim profile and sleek design, it is clearly a premium design and it feels like one. However, a phone is about more than just its looks, and one of the most important aspects of an enjoyable phone experience is good battery life.

So how does the HTC U Ultra do in terms of battery life?

After all, the HTC U Ultra is a 5.7-inch phone with a Quad HD (1440 x 2560 pixel) resolution and only a 3,000 mAh battery on board. Such a battery definitely seems small for such a demanding display, but we were hopeful that HTC has squeezed the most out of it.

Well, we have some good news: the HTC U Ultra is far from a disaster in terms of battery life, it in facts handles itself well. With its screen set to 200 nits, a luminance level comfortable for indoor use, we got a battery life score of just below 7 hours. Just slightly worse when compared to the Galaxy S7 Edge and the Google Pixel XL, and better than the OnePlus 3T.

Battery life (hours) Higher is better
HTC U Ultra 6h 56 min (Average)
HTC 10 7h 10 min (Good)
Apple iPhone 7 7h 46 min (Good)
Apple iPhone 7 Plus 9h 5 min (Excellent)
Samsung Galaxy S7 6h 37 min (Average)
Samsung Galaxy S7 edge 7h 18 min (Good)
Google Pixel 7h 45 min (Good)
Google Pixel XL 7h 19 min (Good)
OnePlus 3T 5h 41 min (Average)
LG G6 6h 9 min (Average)

At the same time, while the HTC U Ultra is just slightly below the mark when compared to other flagships, we have recently noticed that all of these phones fail much shorter of the amazing battery life that much more affordable phones provide. We have just recently tested the sleek and very affordable Lenovo P2 and got slightly south of 12 hours on the same test! There is clearly something more that flagship makers could do since even those cheaper phones get much better life. Maybe a Quad HD display is not the best idea for a phone after all?

Charging time (minutes) Lower is better
HTC U Ultra 100
HTC 10 100
Apple iPhone 7 141
Apple iPhone 7 Plus 197
Samsung Galaxy S7 88
Samsung Galaxy S7 edge 99
Google Pixel 119
Google Pixel XL 118
OnePlus 3T 85
LG G6 97

Another key aspect of the battery experience of a phone is the time it takes to fully recharge its battery from 0 to 100%. The HTC U Ultra does well on this test: it fully recharges its battery in just 1 hour and 40 minutes, almost exactly as long as it takes to recharge the Galaxy S7 Edge, and much faster than the slow-to-charge iPhone 7 and 7 Plus.

We are also hard at work on our full HTC U Ultra review that should be coming up soon. There we will look at the performance, camera quality and more about the U Ultra.

How is that surprising at all? It scores the same as any other 3000 mAh SD820/1 phone. Anyway, all the reviews show that in real life, it delivers spectacularly poor battery life and much below most other phones.

Are you saying that from experience? For all the phones I've owned, PA's battery life test is quite accurate, within a margin of 40 mins to an hour. My M8 got me 7 hours max from 100 to 0 in one go, my Droid Turbo does 10 hrs 34 min. So i know that if i buy an U Ultra it'll give me around 5 hrs screen on time in about 16hrs of usage. That's not bad battery life.

16. Tyrion_Lannister unregistered

Except most reviewers say it doesn't even give 3 hours of SoT. Also PA is the only site which says that regular iPhone 7(not plus) beats the S7 edge in battery life. Also S6 edge beats S7 edge in battery life. PA's test was good for old phones since their processors used to be pegged at good load. Nowadays, CPUs are mostly idle since how fast they are, and hence PA's CPU centric script is pretty useless.

"Nowadays, CPUs are mostly idle since how fast they are, and hence PA's CPU centric script is pretty useless." Thanks for the insight. Now I've got another reason to not take PA's battery test seriously. SMH

Oh hey, I got the blog working again and my timing figured out. You can expect a new article every day. I have today's article up now and a week's worth of stuff planned and in drafts. Sorry it took so long.

Oh s**t, @Tyrion_Lannister . I've somehow lost the bookmark, as I had switched to another browser. Can you give me the link to that blog again? Thanks.

Nice blog. Thanks for your time and effort.

36. Tyrion_Lannister unregistered

The real effort will come in a few days. I have some solid plans for it.

You have a blog?

38. Tyrion_Lannister unregistered

I had a blog, and it was quite popular(100k hits in a couple months). However, due to academics and job interviews, I shut that down. This is a new blog and there's not much to it, and the content as well popularity is low, but I mean to get it done right. Anyway, here's the link: https://goo.gl/AyTz8l Any feedback/ideas would be highly encouraged.

Faster CPU= faster at race to sleep Tyrion no? If you can do something as fast as possible and then go idle, that's optimal. But in the name of scientific testing, a constant workload , while not exactly representative of daily normal usage for most, is more scientific in determining which one is actually"more power efficient and better" in regards to this

23. Tyrion_Lannister unregistered

It doesn't actually work like that. A constant workload can be different for different processors. For example, consider a load which is properly scalable such a rendering. Now imagine doing this in a loop. So an SD820 will do maybe 100 renders an hour while an SD625 does only 30 an hour. Even if SD820 phone dies in 7 hours and 625 phone in 14, the 820 phone did more renders. Constant load can be scalable or not. And unless we know what PA's script is, I can't say anything. But it sure looks like something which punishes SD820 quite badly compared to every other processor, even high end ones like 8890 and A10. And the 820 is not that bad when you consider perf/watt according to anandtech. All I want to say is that there is something fishy going on with PA's script.

25. mikehunta727 unregistered

Hmm okay I understand. And yeah the 835 perf/watt should be significantly better then the 820/821. 820 doesn't have bad perf/watt true that

Hmm...How old of phones we talking about. Before snapdragon 600?

41. Tyrion_Lannister unregistered

Before 810. So around the 800 era or before.

The PA script is just not very friendly towards the S820 for some reason. I'd truly like to see them test the Exynos S7 for comparison.

43. Tyrion_Lannister unregistered

They did test the exynos s7. The exynos s7 did 10 hours 44 min. If they did the edge, it must have got around 13 hours.

I am more surprised with how the hell iCrap7 outlasted these premium Android phones. If you go outside iCrapArena, iCrap7 is dead line in battery test.

PhoneArena test is basically useless. Stand-by power draw (the mode a phone spends much of its charge in) is not taken into account. Go to other sites for realistic battery life tests.

PhoneArena, you guys need to overhaul your battery life test, it poorly replicates the real battery endurance of the phones you are testing

Hi All, just skip PhoneArena battery tests. It's crap. The results are all over the place. Not consistent with any of the other tests conducted by other tech sites or popular feedback.This place is better for all-in-one place scoop compiled from various sources but not serious tech analysis.

Funny how the iPhone 7 scores better than the S7 Edge lol
