Try a game or music. The screen is gorgeous and the sound is great, though some have had grievances with crackling at high volume(I haven't had this issue).

The battery life is pretty impressive on its own I'm at 46% after 12 hours of somewhat regular use. If I want so accustomed to AOSP I'd probably be fine with leaving it stock.
[Verizon HTC One (M8)] ocman40:
Used it all day and was on it pretty much all day. 7am till 11:45 pm and it was at 39%. Pretty darn impressive.
[Verizon HTC One (M8)] ihavenewnike:
Wow, sounds great. I listen to a lot of music so this needs to be good. I might just have to invest into an external battery charger, to be on the safe side
[Verizon HTC One (M8)] oneandroidnut:
I have crackling at high volumes only on certain songs or videos. is that normal?
[Verizon HTC One (M8)] shook187:
Was normal on several 2013 HTC Ones I've owned
[Verizon HTC One (M8)] oneandroidnut:
im taking mine back to Verizon tonight I don't like. my max or og one never did it
[Verizon HTC One (M8)] dansavi:
Yeah, I would. I had that issue start to come up with my M7 but I listen to everything at highest volume so I'd assumed it was my fault, and I was getting the M8 2 days from that point so I shrugged it off. Now it seems more like it's a fairly regular issue, maybe just a bad batch of speakers.

Try using G Wallet too, OP. Multiple confirmations its working but I'm not seeing any functionality here.
[Verizon HTC One (M8)] Div033:
One website I always trust for battery reviews is laptopmag.com ... They use a standardized test across all devices that mimics how I'd normally use a device; it constantly surfs the web on wifi with brightness at around 40% til the battery is completely drained. I find their results to be similar to my own.

I was blown away by their result with the M8 - it lasted a total of over NINE hours! It surpassed even the LG G2 which was close behind.

Surfing over the network is another story, I'd predict the same test to yield a 6-7 hour duration on LTE, which is the same as what I get with my GS3 w/ 3000mah extended battery. This life is perfectly fine for me and I rarely need to plug in before bedtime.

I'd like to know if anyone's experienced stellar battery life of constant web surfing like they're reporting.

pretty heavy usage throughout the day. Looks to be on track to get 6 hours screen on time. I got 5 hours at best on the m7 which was already impressive. I'm definitely happy so far. this. is only the first full drain as well.

I will use strictly lte on my next full drain.
[Verizon HTC One (M8)] Olddog828:
Had about 58% when I hooked my charger up last night after a day of heavy use (for me anyway). Very happy with how well the batter is doing so far!
[Verizon HTC One (M8)] oneandroidnut:
I took back last night and Verizon employees agreed the top speaker sounded awful and different from floor model. swapped out with a new one no problem and sounds much better although still not perfect but doesn't do on every song like old one just a select few. I think its just those parts of the music. boy I need viper audio!!
[Verizon HTC One (M8)] travisryans:
Impressed

I turned mine on for the first time yesterday at around 1PM, CONSTANT heavy use through 8 PM or so. I left it on over night assuming it would die as my old SG3 would die on a full batter within 5 hours because I have terrible service in my house, woke up to 21%. Did my usual checking of emails etc for a few minutes. It's crazy to not see the battery dropping as I use it. Impressive to say the least. Now if I can just figure out what setting carried over that is preventing the LED from working but that is noted in a different thread.

Edit: Forgot to mention current time / percentage: 9AM 15% Battery

[Verizon HTC One (M8)] overlord727:
Ended yesterday with 62% battery, 2.5 hours on screen time! Not bad!
[Verizon HTC One (M8)] norock:
I'm absolutely thrilled with the battery life of this phone! Thing is, though, I upgraded from a VZW Galaxy Nexus. I'm pretty sure any current-gen phone would have given me a similar reaction.

U WOT M8?
[Verizon HTC One (M8)] celblazer:
Very Happy with battery life

After 1st full charge, I'm at 1 day 2 hrs and 14% left with just above normal usage. Leaps above the old Droid 4 I came from.
[Verizon HTC One (M8)] ihavenewnike:
Battery seems to not be a problem, but now i am hearing the camera is atrocious.
[Verizon HTC One (M8)] Tigerstown:
I dont have that issue on this phone or neither one of my blue m7. I would take that back.
[Verizon HTC One (M8)] Izeltokatl:
It's lasted a full day with plenty of battery to spare. I'm impressed so far, I'm on day one.
[Verizon HTC One (M8)] Kamar234:
I don't get that all. I used the phone for an hour of web use this morning from a full charge and was down to 78% my phone is also a bit warm as well. Could mine be defective?
[Verizon HTC One (M8)] mchief298:
Battery is starting to get a bit better. :)
[Verizon HTC One (M8)] TheBiles:
Screen-on times, people. That's what we need. "I used it all day" doesn't tell us anything.
[Verizon HTC One (M8)] mchief298:
I'd say about 2-3 hours for mine. It's kind of hard to tell screen on times without a third party app.. I tried the battery monitor, but it actually took more of my battery, maybe I did something wrong.. I don't know...
[Verizon HTC One (M8)] celblazer:
I'm at 2hr 51 minutes of screen time with the phone off the charger for 1d 2 hr and 14% left
[Verizon HTC One (M8)] Kamar234:
I feel the same way. I think it's kind of ridiculous that HTC has hidden that from view. I either have a defective unit, or this screen absolutely decimates the battery of this phone. I just charged up to 100% and put a battery monitor on, so I'm going to see what's up.
[Verizon HTC One (M8)] rifler26:
IMO the auto brightness is waaaaaay higher than it needs to be.
[Verizon HTC One (M8)] TheBiles:
I didn't even realize it was hidden until now. That is a very strange decision of them.

[Verizon HTC One (M8)] ed-flip:
Mine so far has been great. I can go 2 days without charge. My usage mainly consists of internet and messaging, no streaming or anything like that. I think my new strategy on this phone is to charge it only when it needs to be charged. I used to plug in every night, and im not sure if that affects anything, but it seemed like my battery life on my M7 consistently got worse.
[Verizon HTC One (M8)] MoNsTeReNeRgY22:
How are you guys seeing screen on time? I can't find it
[Verizon HTC One (M8)] razortaz18:
Screen on time while very useful, doesn't tell the whole story. I may be a little different but the majority of my battery usage is with the screen off. I stream music to a Bluetooth speaker for 8+ hours a day and also use GPS (with screen off) to track my exercise approximately an hour a day.
[Verizon HTC One (M8)] NoFanboy:
I had 5 and a half hours on screen time and 1 day and 3 hours total according to gsam. The days before my battery life wasn't close to this, it took a few days to calibrate.
[Verizon HTC One (M8)] Kamar234:
I hope that just happens to be the case with mine. I haven't been seeing the results that everyone here is getting.
[Verizon HTC One (M8)] mchief298:
How long have you had it? My first two days were meh.. but this latest charge was pretty good. :)
[Verizon HTC One (M8)] XfrostX:
Holy ****. 5 Hours of screen time??

10hr 43 min of usage.
[Verizon HTC One (M8)] Kamar234:
I'm actually on the second day. It looks like I'm get about 3-3 and a half hours of screen on time. Hopefully it greatly increases.
[Verizon HTC One (M8)] javaguy110:
It's not an HTC decision. It's a Kit Kat change that limits what you can see without root. Check out this link from the Better Battery Stats developer.

https://plus.google.com/app/basic/stream/z12pgfihfuzns1ewn04cebxizkujc34jxbg

I use Gsam to track my usage and had 4+ hours of screen time with 20% battery to spare. Coming from a Rezound, this is awesome!

[Verizon HTC One (M8)] Kamar234:
Thanks for trying to answer my concern.I came from a droid maxx, and you can see it on there even though it also runs kit Kat. It seems that the poster on that link is complaining about how Google has changed the way that android reports battery stats breaking his app, not that android itself has removed that feature completely. It seems as though HTC made that call for some reason. Thanks for even looking into this though.
[Verizon HTC One (M8)] jsms0905:
Wow so battery is blowing me away, I know it's not much screen time but it's lasted a lot longer than I expected, almost 24 hours and a little more than 50%!? Especially with everything on!
[Verizon HTC One (M8)] digitalhigh:
Got mine yesterday at 11AM. Used it heavily while setting it up and made it till about 6PM before having to plug it in. I didn't check the stats, but that's gotta be around 6 hours of near constant network and screen usage and it hung in like a champ. I expect that after a few full charge/deplete cycles, this should easily beat my M7, which I could use lightly over two days with no charge and still have 40%+ battery left.
[Verizon HTC One (M8)] nasseem:
How fast does it charge? The m7 would take forever to go up a couple percent while my s4 and note 3 would go up 10% in the same time
[Verizon HTC One (M8)] digitalhigh:
As usual, it depends on the source. On laptop, I gained about 20% in...about an hour? Wall charger is faster, but I haven't bothered timing it.
[Verizon HTC One (M8)] nasseem:
Thanks for answering but on a wall charger, if it charges quicker than the m7 I'll be happy
[Verizon HTC One (M8)] celblazer:
Here are my stats
[Verizon HTC One (M8)] steelersmb:
Man, my battery is acting very weird. I had 94 percent before my phone rebooted and now it's showing 84% after it booted back up. I have been getting pretty poor batter life so far. My battery seems to drop by 1 percent pretty quickly when the screen is on. Also I found the Gsam Battery isn't reporting the screen on time accurately all the time.

This is frustrating as I see other people reporting 5 hours of on screen time.
[Verizon HTC One (M8)] Moose3:
I just got the phone yesterday afternoon. It arrived with 50% charge out of the box and I didn't bother plugging it in until I went to bed last night. Yesterday, my battery life seemed awesome. Today, it's less stellar. I spent an hour or so last night setting up some of my must have apps. Dropbox, facebook, tweedle, office, soundcloud etc. I hope I'm not having an issue because of one of those. I'm about to charge it up to 100% with GSAM battery monitor installed and see what I can figure out.
[Verizon HTC One (M8)] Zorachus:
Exactly. LOL.

You can show a screen shot of 32 hours. But without seeing the On Screen time that 32hours can be very deceiving, and mean you barely used it for the day.
[Verizon HTC One (M8)] sincerity:
my battery life initially was decent. after slowly adding apps though it seems like i am at 50% before I know it...
[Verizon HTC One (M8)] huichan:
Not that impressive

Battery life on M8 seems to be par with Galaxy S4 and I am not all that impressed, especially coming from Note 3.

I read some great review about this phone's battery life but it is nowhere near what I have experienced from Note 3.

I just had my third cycle. Having 2 hours of screen time sitting at 36% and 10 hours of usage.

I used to get 5 to 6 hours of screen time with 36 hours of usage with Note 3.
[Verizon HTC One (M8)] Kchitown1977:
I'm lil over 20 hours 3 and half hour screen time @30 percent battery
[Verizon HTC One (M8)] rifler26:
So far today had about 2 hours of screen time on with a bit over 2 hours bluetooth audio streaming, and I'm at 55%. That's not that great tbh because I have GPS/Wifi/Data off unless I'm using it, I've got a bunch of apps Greenified, etc, etc. I mean I am coming from an S3 that had a 3000 mah extended battery on which I could get an hour screen time per 10% use on wifi easily. I'm not expecting anything near that here but I still can't help but feel a bit disappointed.
[Verizon HTC One (M8)] Moose3:
This is where I ended up today with my first normal day of usage. I refuse to toggle wifi/bluetooth on and off. My screen brightness was on auto adjusted towards the brightest setting.

I'll never understand how some people get 5-6 hours of screen time. I've never been able to replicate it on any phone I've ever owned.

The M8 so far is performing probably a little better than my Galaxy S4 did. I'd say the M8 is pretty equally matched with my iPhone 5S battery wise.

Overall I'm happy, nothing spectacular.
[Verizon HTC One (M8)] peejay09:
So much better than my DNA...
[Verizon HTC One (M8)] sfreemanoh:
I don't have the numbers, but I'm getting significantly better battery life than on my old GNex. I'm one of those also getting a lot of drain from android system though, so I'm sure it could be a lot better than I'm getting.
[Verizon HTC One (M8)] xShin:
I've had my M8 for a week now, and according to GSam Battery Monitor, my average screen on time is 5h 33m per complete charge, with an average battery life of 1d 3h per complete charge. This is taking into account that I do lose signal sometimes on my commute, when going through subways and such. If I'm streaming video, 1 hour of streaming video roughly equates to 13-14% battery for me.

My data is always on, WiFi is always off, screen brightness is set to ~50%, with email and weather set to automatically sync.
[Verizon HTC One (M8)] sitlet:
Haven't installed any battery app yet, but I'll give you what my stock settings say.

Got the phone on Sat, so full charge going into Sunday. Left home at about 9am, was at work from 1pm to 10:30pm. Where I work is a downtown area, where previous phones would just drain and drain due to so many people on the network. My last phone would literally die in about 7 hours of zero usage, or about 1 hour of heavy usage. I did not charge the phone once, and I got home about 11pm and still had 30% left.

Today, left home at 10am with 100% charge to the same area. Worked until about 5pm, with pretty heavy usage. Drove for two hours using the phone to play music the entire time. Went to my second job from 730pm until midnight, where I work in a basement and literally have one bar of service. Just got home (1230pm) and I STILL have 43% left. Never charged it since 10am.

I am absolutely amazed. My last phone had a 1900ma battery, and wouldnt last a few hours at either of my jobs, let alone 15-16 hours with fairly heavy usage.
[Verizon HTC One (M8)] d1ez3:
How did you manage that? What apps were you using, ect
[Verizon HTC One (M8)] peejay09:
Let's see...

No auto brightness, kept around 33%

All wifi, only switched to 4g for a few minutes.

Area with good signal strength the entire time helps

I have NFC and BT turned off, I leave everything else always on

Apps were a mix of reddit, tapatalk, maybe 10 pictures on the camera, some snap chat, bunch of sms.

I ended up with over 7 hours screen on in 30+ hours and was still at 12 or 15%. So although I'm not trying to optimize for best battery, if you have some of the conditions above and no rogue wake locking app, you can get some awesome battery life.

(PS - One thing I did do which I heard on here is turn off the "Ok Google" hotword detection under voice settings in the search app. My play services batt drainage dropped significantly the next day after that change.)
[Verizon HTC One (M8)] Kamar234:
Ok guys. I know I've been on here saying how disappointed I was in the battery, but wow! After letting it settle for three days. I got a projected 1 day and 2 hours of charge time, and over 3 hours of use, and today after working a full day, I put on Netflix with the intention of killing the battery. I purposely ran it on 4G as well, and I attached my stats. Very pleasantly surprised.

Also, I was running on auto with max brightness range, dropbox, google plus, gmail corporate email, facebook, linkdin and everything else running with no limitations. Impressive. Most impressive.
[Verizon HTC One (M8)] nekat:
Battery was my one area of concern coming from a razr maxx. That concern is gone. I can easily make it through 24 hours.
[Verizon HTC One (M8)] steelersmb:
I don't know why some people are having awesome battery life and some aren't like myself. I charged my phone to 100% before bed, used it for 13 minutes, went to bed. Woke up, drove to work, about 25 minutes, listening to BT musing and I'm down now to 85% already. That with only 15 minutes of on screen time. I have disabled everything I could. This is very frustrating.

Also, at night, data gets turned off as well and so does WiFi so the only thing on is the phone.
[Verizon HTC One (M8)] kj13569:
I feel your pain bro. I am having similar results. I keep everything off, I've disable google services framework but do not see a way to disable google services. It keeps running in the background even when data is off. I've also turned off all location reporting but HTC weather service still starts by itself (still no data on the device). And since Tuesday i've been getting these weird battery stats the dont make much sense...

If anyone could enlighten us on wtf is going on with this battery when everyone else says "it's so great omg!". We must have broken phones or damaged batteries or something. I feel like going to the Verizon store for a swap, I'm at a loss...

It seems like every time I unlock the device and send a simple text it goes down by 1%.

Battery life

2nd full day and way better than my s3!
[Verizon HTC One (M8)] steelersmb:
I backed up everything just now and did a full restore. I am going to see if that helps but if not, I may return the phone and go back to my LG G2 for a while.
[Verizon HTC One (M8)] kj13569:
yeah same here, something has to be faulty if it ain't software then it's the hardware. Keep me posted on your results since everyone else just skips over our posts.
[Verizon HTC One (M8)] sfreemanoh:
For myself and some others, it was an issue related to Google Now, and more specifically Location Reporting. While obviously to get full functionality you need to leave it enabled, I'm getting RIDICULOUSLY better battery life with it disabled. I'm at 84% battery right now, with almost 45 minutes screen time, and almost 7 1/2 hours off charger. I know the screen on time isn't that much, but before turning Location Reporting off, my battery would have been probably twice as low.

I've seen this issue frequently on my old GNex, and turning off location reporting helped then as well. It just seems to be an issue Google needs to work on, or we need to live with. Though that being said, I don't know why it doesn't affect everyone the same way? Maybe it's dependent on your GPS coverage? I'm inside most of the day at work, so the GPS coverage may be nill (but I haven't checked).
[Verizon HTC One (M8)] bkdodger:
I've tested 4 days so far.. Add me to the list with not seeing that great battery life... I don't use wifi...signal good in NY... Same set ups like my other phones.. I'm not keeping phone but curious why it's not lasting enough...

[Verizon HTC One (M8)] Kamar234:
I'm not sure how long you've had the phone, but I used the HTC Transfer tool coming from a Droid Maxx, and something was weird with the software. I wiped the phone and had Google reinstall everything from the playstore. For the first three days my battery life was horrific, and I planned to return the phone. I was getting around 2.5 hours of screen on time from a full charge. Then on the fourth day, it jumped up to almost 5 hours of screen on time from nowhere, and it is looking like it is going to be around there again. You should give it a week or so to see if that happens. I was confused and pissed and thought I had a faulty unit. It is strange because it seems to quickly drop percentage points when you first use it to do something, but then it starts to slow down on the draw, even though you are still doing the same thing. It's like it needs to learn what is the least amount of power it needs to do something after a couple of minutes.
[Verizon HTC One (M8)] superjshorty:
I work in a retail mobile store for VZW and am basically on my phone constantly. When we are slow, twitter, Facebook, YouTube, etc. For the last week I've gotten 15-17 hours consistently. I've been very impressed!

Sent from my HTC One M8
[Verizon HTC One (M8)] rifler26:
The other issue I've seen is that GSam reports times wrong. I've had several days where the hours of screen time jump by as much as an hour and a half for no reason whatsoever. Maybe that's what some of the people with great battery life are seeing if they only check GSam at the end of the day?

I listened to Bluetooth for about an hour and 45 minutes and have 25 mins of screen time on and I'm at 82%. That's pretty meh in my opinion.
[Verizon HTC One (M8)] steelersmb:
I disabled all of that and some other things and it didn't help me. I also froze most of the apps that I could...didn't help either. Nothing I do seems to help. I just wiped my phone and starting over. I'll see if that helps.
[Verizon HTC One (M8)] kj13569:
Yeah I didn't use it at all I moved everything over manually and I received mines on 3/27 battery was on 47% and used it to the max and was very impressed with the battery. As soon as I started charging it and took it off the charger that night the next morning it was on 90% and I literally just set an alarm... so from 10:00pm to 6:00am it went down 10% with no data, no wifi, no gps, no nfc, no bt, no nothing on but cell service.

And at first it was the location thing but I turned everything off and HTC weather still comes up and I get 1% lower every time I use it. My battery stats are the most confusing because it states Dialer is taking 60% and kept the phone awake for 58mins... I don't get it.
[Verizon HTC One (M8)] Kamar234:
That is strange. this phone does some strange things sometimes. The battery looks to be draining really quickly on mine, but when I do the math I realize at its current rate, it will last 5 hours with the screen on and being used. You should try to use it a few days, even with it seeming like it's going to die quickly. It sounds strange, but burns at a pretty narrow range, whether it is idle or not. I looked at it and it burns 2-3% per hour on idle, and when being taxed, about 10-15% but it feels like it is 8-13% if you have the screen on. Yes, I am going that deep I to my analysis haha.
[Verizon HTC One (M8)] faded03cobra:
Mine was terrible the second day I had it. Lost 49% in under 6hrs while the device was completely idle.........did not use the phone once. Reset the phone when I got home from work and since then it has been great.

By reset do you mean a factory reset? Curious because I am getting odd battery drain when my phone just sits there through the day

I did a hard reset today and so far it seems better but not enough time to tell. I also enabled the battery saving option.
