Battery Life
The new One features an integrated 3.8V 2600mAh battery (9.88 Wh), a 13% increase in capacity compared to the previous model. The battery comparison isn’t that simple however. The M8 has a larger display (5” vs 4.7”) but it also has a higher performing and more power efficient SoC (Snapdragon 801 vs. 600). To find out how the new One stacks up against its predecessor, we turn to a mix of old and new battery life tests to help better characterize the device.
We’ll start with our standard browser based battery life tests. Keep in mind here these tests are as much about replicating a particular CPU profile as they are about loading specific web pages in order.
We saw a substantial gain in battery life with Snapdragon 800, and 801 extends that even further. For the same, relatively light (yet constant) workload, the M8 improves battery life over the M7 by as much as 71%. On WiFi the advantage drops to only 38%, but we’re still talking about absolutely huge generational gains.
A constant workload is only one part of the story though. More often than not, when you’re faced with faster compute you end up doing more. To see what the other extreme of battery life looks like I turned to two canned tests: BaseMark OS II and GFXBench 3.0.
I ran both of these tests under the same controlled conditions we always use, with all displays calibrated to 200 nits. BaseMark OS II runs through a bunch of CPU and storage benchmarks (basically the same tests used for the BaseMark OS II system and memory tests), as fast as possible, until the battery dies.
I like this benchmark as it gives us an indication of worst case battery life if you’re absolutely hammering the CPU (and storage) relentlessly.
Despite the faster CPU cores, the M8’s battery life actually goes up compared to M7. Here we’re really seeing the benefits of 801’s updated 28nm HPm process compared to the Snapdragon 600’s 28nm LP process.
GFXBench provides a similar test, with effectively uncapped performance (on today’s devices at least since we’re not hitting v-sync limits), but stressing the GPU instead of the CPU. Here we’re running the T-Rex HD benchmark, onscreen, until the battery dies.
This is the first and only test we’ve got here that shows a regression in battery life compared to M7. The M8 loses about 6% of runtime compared to the M7, despite having a larger battery. Now look at what happens if we look at performance at the end of the run:
Now the M8’s battery life regression doesn’t look so bad. You give up 6% of runtime but you get almost twice the performance compared to M7. Snapdragon 801 is just a huge upgrade compared to 600.
Charge Time
The M8 features a Qualcomm Quick Charge 2.0 enabled PMIC, which enables faster battery charge times through higher voltage charging. Unfortunately the in-box wall adapter is only Quick Charge 1.5 compliant so you'll only pull 7.5W from the wall. HTC expects to offer a Quick Charge 2.0 compliant power adapter later this year.
The M8's charge time is a bit slow compared to what we've seen from other devices with larger batteries.

I think if you compare a 2MP and a 8+MP picture by looking at it on a 2MP-5" screen, about 100% of the people will not be able to tell which one has the better resolution.But I agree with your general comment, people complaining endlessly about the photographing qualities of a device that can't be connected to a good objective anyways is just weird.

Sorry I don't agree with you. 4MP is lots for twitter and facebook, but you can't crop the image at all. Plus 4MP doesn't allow 4k recording.Also they took out the OIS. The camera is fine in the One, but it's a regression from last year's model. That's why it's getting knocked. People had issues with the camera last year, and now they've actually gone back a step rather than address the issues.
Don't forget you're not talking about a Lumia 520 here, or even a Moto X. This is a full flagship phone, with the price to match. They needed to put a larger physical sensor in this year. If they had done 6-8 MP with the "ultrapixels" that would be one of the best camera's on a phone. Instead they regressed. That's never what you want to see in a flagship and they've been rightfully called out on it.

Don't you ever, like, zoom in the photos?For, you know, seeing the finer detail?

Depends. While I do a lot of cropping of my photos, I usually use Photoshop for that purpose. Does the job better than most mobile apps (including those that come with the phone itself). But for the average person, cropping is a rare event. In fact, you would be lucky to talk to someone who regularly crops smartphone camera photos for detail purposes.So Jonup does have a point. Doesn't mean that the M8 suits your needs; to each their own on that one. But for most folks -- including many professional photographers such as Mahmoud Mfinanga of EmmazedPhotog.com, and Colby Brown -- the M8 (and the M7 before it) more than does the job.

You do realize that most of the actual, professional photography work that Mahmoud Mfinanga and Colby Brown do uses either film or high end DSLR's cameras right? I mean it's literally on their websites. And no, the M8 and M7 would not cut it for them.doosh bag - Friday, March 28, 2014 - link
They didn't say they used the phone camera, they simply endorsed it. Have it a thumbs up, if you will.CoryWeston101 - Monday, March 31, 2014 - link
I know a few that would disagree. And believe the M8 and M7 have great camera's for smartphones.sephirotic - Sunday, March 30, 2014 - link
Finer detail, on 16mpx 1/3" sensor? Good joke, sir.CoryWeston101 - Monday, March 31, 2014 - link
No. That's stupid.jond11 - Thursday, March 27, 2014 - link
Maybe you should do better research. The camera improved from last year's model even with them removing ois. Not one tech site yet said picture quality is worse on the M8 compared to the M7. Actually, anyone who reviews the 2 phones all agree it takes better pictures. It's funny how the HTC ONE 2014 performed better than any phone on the plantet, but it wasn't worthy because it had a 4 ultra pixel camera. Yet the Note2, Note3, and S4 don't perform half as smoothly as the ONE and was considered great phones. So Iguess iit's ok now to make flagship phones buggy and filled with lag as long as it carries a 8 megapixel camera or better, lol.
