With heavy use on my m8 this is what I'm getting everyday who have is more than enough for my day to day
[One (M8) General] cheno1115:
I might cough up the dough and get better battery stats. That would tell in detail what inside the kernel is using all the battery. It would most likely be the culprit across all our devices.

Someone on the Verizon M8 forums suggested that maps was causing kernel wakelocks, and by hibernating maps, it greatly increased battery life.

I use maps too often (delivery job) to disable it however. Will report back here with the results.
[One (M8) General] alhadee12:
Can you show your app usage with a screen shot.
[One (M8) General] alhadee12:
Thanks, the kernel it's very high on my phone and even when I make adjustments it says the same. It's always in the high 60's.

Battery life sucks ? I was looking for a new smartphone, and thought this M8 got like 5h to 6h On Screen time ?

HTC One (M8) Review

http://www.droid-life.com/2014/04/07/htc-one-m8-review/

Battery life not good on the M8 ?

HTC claims that the new One (M8) could see upwards of 40% better battery life over last year’s M7, but I’m not I’m buying it. I saw average battery life in my testing on the 2,600mAh battery that wasn’t necessarily greatly improved over last year’s One. My testing typically includes multiple days in a row of nothing but 4G LTE, followed by a few with WiFi mixed in. On 4G LTE-only days, my phone was almost always begging for a charger after 10-12 hours of use and around 3 hours of screen-on time.

Per this review they say battery life is average at best, and not that good, only getting 3h On Screen time, and overall just like 10h - 12h of total battery life on the phone, and with WiFi on they get 14 hours total battery life.

I thought all the real world reviews of people, and other sites were raving about the battery life on this new One M8 ? getting like 5h to 6h On Screen time ?
[One (M8) General] Rachorid:
Battery life on the M8 is great. HTC promised 40% better battery life. Well I'm getting more. My M7 averaged about 3-4h On Screen time. I can't say something specific about my m8 cause I'm flashing a few ROMs but even after I flashed a ROM (battery drain is always horrible before the first Charge) the M8 is better than my m7. I'll post some screenshot once I have a good ROM set up and a few charges so it can use it's potential. According to my calculations I should get 7-8 hours. I also posted a screenshot a few pages ago of my first Charge ( 3+ hours and 53% left).

By the way.. most Reviews Forget it's insane "off Screen" time. Sense 6 is great optimized, I don't turn off Auto sync etc and I'm losing about 1-3% overnight (8 hours).
[One (M8) General] bia9977:
Let me put it this way: on M7 I was getting around 4hrs screen time. On M8 with same usage am getting close to 7.5hrs. Battery is definitely better. Far better.
[One (M8) General] ryno9100:
Forgot to mention that. My screen time usually averages between 6 and 9 hours a day.

Another thing I forgot to mention is that I do use Greenify non-sparingly(i pretty much hibernate everything that isn't a widget), so wakelocks are virtually non-existant on my device, which makes a HUGE difference in battery life. Had to buy the donator pack today since apparantly Twitter (which is a system app on the M8) likes to run in the background, even though I've never launched it,whether on my M8or my M7. Don't even have an account.
[One (M8) General] sebsal:
I think the battery life is amazing. Coming from the M7, I can't believe how much better it actually is. Normally I would charge my phone every night. Last night, after a days use, it was at 70%. It's currently at 48% having been on 1 day 18 hours with close to 5 hours screen on.

I'm going to run it to 0% just to see how much I can actually squeeze out of it. The of course there's "power saver" and "extreme power saver" modes that would get me even longer!
[One (M8) General] mushages:
First charge note this is only 50% usage as I didn't charge the phone fully so about 4:30hrs screen on for 50% and for 14:30 hrs ... Not bad I'm sending this post and charger not connected yet. And for guys asking about how I use the phone :

- power saver on

- autosync on but not for mail

- tapatalk, 9gag, whatsapp, BBM, talkray, YouTube, twitter, Facebook, instagram, snapchat, browser. And whatever I want but those mostly
[One (M8) General] cheno1115:
Okay I thought I had the kernel issue solved with sync and HTC backup disabled. I was wrong.

Can anyone interpret these?

Sorry for all the image links. Wouldn't let me upload them as attachments.
[One (M8) General] mushages:
Did you try to factory reset?
[One (M8) General] CyanideIII:
Really have no idea man

But i have these suggestions for you:

-Take it easy and enjoy your phone

-Do a clean install

-wait for other comments for better results

Sorry mate
[One (M8) General] rj.camargo:
Hey here are the images from gsma, the battery is a little high but it think it works. I forgot to take a screenshot of the kernel wakelocks but at this moment I have 73% battery left and the kernel wakelocks screen shows the following:

Combined App Wakelocks 1h22m

PowerManagerService.Display 1h07m

bam_dmux_wakelock 53m

APPS_RIVA_BT_CMD 37m

The other wakelocks are really small compared to this ones. So I guess the Display one is from the screen because I have 1h15m of SOT at the time. The thing that seems off is the first one because as you can see in the screenshots the apps don't show a significant amount of time held awake si I don't know what could it be. My guess is the high count of times waking the devices by google services and facebook apps.

What do you think?

Ohh and about the kernel, it happens with all the kernels I've tried (Quantum, ElementalX and Hypernova).
[One (M8) General] lilliput222:
What is android kernel "main" wakelock , its bugging me from last 2 days
[One (M8) General] JellyKitkatLoli:
Not even close to the full potential, heck 3 hours is stretching it for me lol don't know how you guys can use your phones for so long.

I guess technically I can sustain over 6/7 hours
[One (M8) General] daddyodizzel:
Coming back to my m8 after leaving Note 3. Been at work all day until 7 my time. Slow day lol. Still surprised that battery life has last me longer than my Note 3.

[One (M8) General] Zubeplanet:
can anobody tell me how much screen on time they have with full stock and everything expect blutooth always on ? and the max time until phone battery is empty.

I am on lollipop and got 3 hours max sot and like 15-20hours battery life.

Are these good or bad stats ? i never use the power save mode and have really everything expect bluetooth on and push mails .....

[One (M8) General] gelo01:
Currently on LeeDroid. Well, i don't have complains on my battery stats, but Google Play Services have ridiculous wakelocks! I believe i can squeeze an hour or more without those. Anyone has the same prob as mine? :(
[One (M8) General] navid0308:
If you don't use Google now

Google settings>search and now>now cards>clear card preferences

also do this

Google settings>location>location history>turn off

You can delete your location history data if you want extra privacy from Google. Location history makes a personalized map of your whereabouts.
[One (M8) General] ext109:
I think my m8 is secretly powered by a nuclear battery!

Well, that or gsam is being buggy.. [emoji28]

Sent from the One
[One (M8) General] gelo01:
Well the thing is, i don't use cards. When i first setup Google Now, i "skip" when it was asking me to show the cards thing, i wasn't really a fan of that. Second is, my location history is turned off, i've never turned it on, i'm now wondering if deleting location history data can make a difference. Thanks for the help mate! Hopefully it would be better this time. :)
[One (M8) General] navid0308:
Clearing location history data may not help but you might wanna clear card preferences. A few times, it had some leftover data that kept Google app making google play services run a lot
[One (M8) General] high_voltage:
Try to go data usage and turn off background sync for google play services + in App ops turn off keep awake for google play services. Keep in mind that this will stop your current location update while on mobile data and will only update on wi-fi. GPS navigation works perfect tho, as the weather... so if you don't share location in chat programs - no problem here. For me that removed GPS from the battery usage completely. It's drains uber little power. Cheers.
[One (M8) General] navid0308:
one last thing i do to get rid of google play services when all else fails

settings>apps>google play services>manage data> at the very bottom 'clear data'

this WONT remove your google account or contacts

then reboot
[One (M8) General] racingmatt1:
This worked perfectly for me,thank you. I also figured out that,there is a app ops for non rooted phones that actually works (I'm non rooted). Just search "app ops no root" in play store and it'll be the first one on the list by "open view mobile".
[One (M8) General] swiftfury:
Is there anyway to get the HTC One M8 battery replaced through HTC? I love my one M8 but after more than a year of heavy useage the M8 has lost almost 40% of its charge.

I do not want to get new phone because I am one of those people who believe HTC One m8 is a perfect phone.
[One (M8) General] PowerBlade:
How did you see how many % of the charge it has lost?
[One (M8) General] swiftfury:
eh, was just an educated guess.
[One (M8) General] PowerBlade:
The reason I ask is because you can get apps for Windows that can measure how degraded the battery is.

I'm wondering why I can't find an android app that can do the same thing.

Don't pull your hair out yet guys. Remember, US will get it first then about 20 days later EU will get it :p
[One (M8) General] jshamlet:
This isn't entirely, or even largely, a HTC problem. Lollipop has reduced battery life across the board. Which is ironic if you think about it - one of the focuses of Lollipop was "project Volta" - which was specifically intended to help battery life...
[One (M8) General] high_voltage:
Not true, my close friend rock sony z3 compact and guess what? His battery was even a little better on 5.0.2 vs kitkat... and yes, he already got 5.1 update previous week. Cool, while we still wait for the update + they didn't release even a small update after the initial lollipop and to nail it we have tons worse battery life. Now with tweaked custom rom/kernel, lower screen brightness and usage for saving battery I got a 7 hours SOT top while on kitkat without any savings, a lot more heavy use and brighter screen I got 8+ SOT and a lot better standby time too... especially on mobile data. And as far as I read most of htc users are suffering the same.
[One (M8) General] iDpC1:
Htc skip 5.1.1 update and go straight Android m update. http://www.ibtimes.com/htc-one-m8-will-skip-511-lollipop-get-android-m-directly-2031381

If they still got bugs in this version, crap HTC, you nailed it.....
[One (M8) General] gelo01:
Why would you want an M9 if you can achieve this with your M8. :P

Well, all we need is our Android M and Sense 7(7.5/7+) update. Hopefully before this year ends, we could finally recieve it..
[One (M8) General] racingmatt1:
How did you achieve this, I have a m7 on sprint?
[One (M8) General] navid0308:
people will always find sth to complain about :P think about this, on the 32gb m9, only 20gb is usable

so consider that for the m8 16gb. after sense 7 internal storage will shrink to ~5gb
[One (M8) General] gelo01:
I have a 16GB version and i don't even have a single complain about internal storage now that i can put a 64 GB SD card on it. I have 100+ apps and i still have almost 7 GB of internal memory. Never bothered me.
[One (M8) General] navid0308:
are you using app2sd or link2sd? There are still a lot of stock users so you gotta consider their scenario! Even if you move an app to sd, there's still some part of it using the internal storage. The BEST solution imo is how android M takes the sd card as part of the internal storage but that's gonna be another long wait for people :P

anyways man, amazing stats! gonna make every m9 user jealous ;)
[One (M8) General] gelo01:
FolderMount to be exact. Doesn't take a genious to know how you can manage to transfer files from internal storage to SD card, since that's the main purpose of having an SD card slot after all, right?

I wanted to upgrade to the M9, but seeing battery stats of it totally makes me hold on to my M8 a little more. What i'm jealous about the M9 is the 4UP FFC, specially for people like me who loves to take selfies with their loved ones. ;)
[One (M8) General] high_voltage:
This is either kitkat or very light usage. I got similar stats on stock 4.4.4 sense 6, but on 5.0.1 is a lot lower even on custom rom. Right now I was same battery life time and only 5.50h screen on time with tweaked rom. Otherwise on kitkat I was almost always on 8hours SOT and that with tons youtube, twitch, facebook, chrome - things that drains the battery + autobrightness on max slider. Oh, good old times. :/
[One (M8) General] gelo01:
I'm on LP. Been using the latest LeeDroid version with 5.0.2 in it.
[One (M8) General] high_voltage:
I am on it. I guess the usage pattern of some doesn't lead to major battery difference while the most of us suffer. Dunno, but I can't get that even with super low wakelocks and semilight usage. Tops 6h SOT for two days, but if you read a lot maybe it can make sense.
[One (M8) General] insane youth:
i know it's a tablet and not a phone but the battery life has improved a lot on my nexus 10 after the lollipop updates, after each version it kept getting better
[One (M8) General] Mastamike:
What is your rom and power saving strategy? Seems really long sot.
[One (M8) General] gelo01:
If you have seen my previous battery stats screenshots in this thread, i've already shared that i don't read. Not even a fan of e-books. What i often read are xda, facebook, olx, and instagram, but reading books online is a big no for me. I can see that you're very skeptical, but if you can't believe what you're seeing, it isn't my problem anymore.

And btw, my ususal usage is powersaver always on because i don't usually game, and if i game, it still runs fluidly even on powersaver (Riptide GP2, Virtua Tennis, Anomaly 2, The Room, etc.), i use Greenify on ALL apps to hibernate if screen is off, i manually set brightness depending on my own visibility, i turn off wi-fi when i'm not using it. That's it. No other BS power/battery saving apps or custom kernels. Plus, i really take care of my battery. I don't game while charging, i don't even use it until it's full, i charge it if the battery is below 20%, usually 15-18%, and i don't unplug it after it has been full, i let it charge for another 15 minutes.

I admit, battery life on KK was phenomenal, but on LP, it isn't that bad. I think i only lost 30 minutes or so in SOT because of bad idle times, but overall, my battery is still great after a year of using the phone. :cool::thumbup:
[One (M8) General] daddyodizzel:
New high for me. A slow day at work for sure
[One (M8) General] high_voltage:
I got 12h SOT screenshot on KK after moderate usage and around 6-7h in chat(whatsup, really great on battery life I guess). :D

I see your point and I don't put your words in question. More the whole situation and how stupid it is for all of us. We are here to help each other and discuss, not to lie. Cheers. :)

12h SOT on KK.:eek::confused:...Dude what rom & kernel please?
[One (M8) General] high_voltage:
Stock, htc did wonderful job with kitkat. Tho this is more of an exceptionary case. Normally without gaming(but heavy usage like hours of youtube, twitch, facebook, chrome, autobrightness on max slider, mobile data usage, etc) I had 8-8.30h SOT and around 19-20h on battery.
[One (M8) General] crazykas:
Cool...Im on KK too due to high battery drain on LP.But my maximum is 5.30 even on KK
[One (M8) General] leandronb:
screenshot or it didn't happen.

youtube is a heavy battery drainer, no way you could achieve 8 hours sot with it. i don't game at all and right now my battery usage is 13h total, 2h:42min sot, 42% left, same settings as you but i dont use facebook, i'm on kitkat 4.3.
[One (M8) General] :
I had an 8 hour SOT average on Kitkat as well. Lean setup, mostly just xda app, browsing and texts in an average day. Manual screen settings.

It's entirely possible. And many did it.

On Lollipop, I've seen it drop to 6 hours average. Though, I use Hangouts now. Only difference, other than Android version.

Edit : does seem to be an achievement using YouTube though. But possible. ;)
[One (M8) General] leandronb:
i tried every setup possible. disabling google now, location, sync, enabling powersaving, greenify and none of this made my sot go higher than 6 hours.

i got 9 hours sot once, but i was on wifi, playing a tv show in 480p in mx player all day with low brightness, so the drain is very low, and lasted a total 13 hours in that day.

on lollipop battery was very bad, 4-4,5h max every day, now on kitkat is better.

when i do things to increase battery life like powersaving mode, location, sync my standby time increases to almost 0% drain, but as soon as i start using the phone with feedly, chrome, youtube, twitter, instagram, reddit(relay) it starts going down like a timer that will ends when device gets 5-5,5h sot.

this week i tried to use stock browser because i feel device getting hot when using chrome, but the battery gain was unnoticeable.

so what is the right settings to get 8hours every day?
[One (M8) General] :
All the advice I'd have is in post 2 here,

http://xdaforums.com/google-nexus-5/help/battery-life-help-troubleshoot-battery-t2785128

It's pretty much generic any device stuff.

But signal strength on data, and everyone's own usage patterns makes a huge difference. One person can average 8, another 5.....all depends what they run, use and their setup and signal.

Hard to compare to one another really.

My old screen shots from Kitkat are buried in this thread way back... But my gsam average times were over months... Not just a few days.

But like I said, that's with my usage and setup. :good:

I'd say 5 or 6 is the common average anyway. From what I've seen here.
[One (M8) General] :
Not showing my current times here... As I've been charging on and off... But my Lollipop averages since may 12th are at the bottom.

I have started using Hangouts since Lollipop came out, so that likely has stolen a decent chunk of my old average.... 8 hours screen time on Kitkat.

I might go back to it. ;)

(use phone a lot at work... And can't charge, so battery life is important to me)
[One (M8) General] high_voltage:
Manually twiked stock rom + wi-fi@work and home = little 3g data usage + winter = darker screen from the autobrightness + youtube was a less battery draining back then(I think it has something to do with the resolution it plays videos auto) and etc. It's possible to get 8H sot with a few(lets say in the sake of numbers, 3h) hours of YT. Nowdays? Hardly. Also messenger is battery drainer nowdays. It's not only about lillipop vs kitkat, really... the software is a lot heavier nowdays.

[MENTION=4869687]leandronb[/MENTION]

We are not here to lie to each other. Keep in mind that when I had 8+ h SOT, others strugled to get 5. It's really individual based on setup/usage and you can mostly compare vs yourself.
[One (M8) General] leandronb:
i didn't mean to be rude, but today is hard to trust very high battery times because back then when i had a galaxy nexus and it had a crap battery some guys posted 13h sot with 2 day usage just for nothing, and everyone was averaging 13h and 2,5 hours sot and this repeated for every device i had.

today i am making another test, everything disabled, powersaving and lowest brighness, i'm pretty sure i will get about 6 hours, mays is some app i use that is heavy on battery, i don't know.
[One (M8) General] high_voltage:
In most cases I find cpu powersaving for worse on battery. Here is a screenshot taken right now. Keep in mind that it's freshly reflashed kernel and still not settled, i.e. it's draining faster the battery than normally would. Auto brightness, no powersaver, little data usage, screen mostly dim, chrome, facebook, messenger, viber, little youtube. :) I will end up with around 7:30h sot if I don't play games/little yt and 7h if I watch more yt videos. Cheers!

P.S. I do think maybe I would have screenshots from kitkat somewhere on my pc, but not sure about that and dont see the point searching for them. Dunno if I backup them or deleted them with the update... I as all of us, expected even better batt life on lollipop. Got one with 13h sot time tho, but it was a lot of whatsup chat(really nice on battery)... like 6-7h atleast. I attached few more from lollipop with settled kernel. Sry for no detailed stats as they where intended for friend of mine who trust me. I can assure you one thing: I used the phone. Cheeeeerrrrsss
[One (M8) General] navid0308:
It also has a lot to do with networks. Im using EU M8 stock rom in Bangladesh and I lose about 1% on standby per hour just to cell standby; sth to do with the band preference. 3G is the highest speed here. If I flash the rcdata.img of Asia firmware, I'll get better standby. But your stats are truly remarkable! I've been able to achieve about 2-3 hours of SOT on my M8 highest. However, I do use FB, FB messenger, twitter, viber, whatsapp with all possible syncs on and I play relatively lighter games like brain dots(it's a must try if you like puzzles!)

I wish my M8 would give me 8 hours of SOT but I'm perfectly happy with it right now. It lasts me throughout the day no matter what I do and I'm sure it's similar for most people. I used to spend too much time flashing roms and tweaking to get the best battery life with the best performance but once I stopped tweaking every day and started using the phone properly, it didn't let me down :) I just wish my M8 would drain like 1-2% over 8 hours or so like an iphone would but hopefully M will give us that!
[One (M8) General] Kristian2018:
