The stock T-Mobile lollipop update is definitely the most battery efficient ROM I've used for this phone. The screen on time is pretty good but the battery it saves with the screen off is absolutely extraordinary. I could go all day with the screen off and lose maybe a percent or two. Screen on definitely drains a lot faster though but not nearly as bad as most other Roms. I'm impressed.
[One (M8) General] Henkhimself:
Hi all,

Been a longtime lurker here but decided to sign up because I could really use help with my battery life. The last few months my battery began to drain a lot faster than usual. I didn't really care at that point because I used to play a lot of games and I thought that was the main issue. After the lollipop update I still have a huge drain, especially during the night. I sometimes lose about 15%-20% on airplane mode while I made sure I put wi-fi and mobile data off before. Location settings are off aswell and I deleted most apps that I don't use such as facebook and some bloatware that came with my phone. The phone is still rooted. I used to be able to get atleast a day or two use out of the phone. Hopefully this is just software related and not something to do with the battery itself:(

I added some screenshots so you might have a clue what is going on. I had bluetooth on for about 30 mins, otherwise it is set off. Screen brightness is set to the lowest setting, signal is usually great.

Thanks in advance!

Without screen shots, no one can help really. ?

But see post 2 in the battery life help thread in my signature for tips.

Everyone uses their devices differently. I get 8 hours screen time usually, but with a very lean and battery friendly setup and in an average day I mostly only use xda premium, browser and text. So ideal usage for battery life. Not everyone will get the same times based on their usage. ?
[One (M8) General] Henkhimself:
Unfortunately I still have issues with my idle drain. Google service has gone back to normal thanks to the updated version but I still lose about 16% at night even while in airplane mode...

Got it off the charger and used the phone for about 30 mins watching twitch. After that I made sure wi-fi and mobile data were off and I switched to airplane mode. These shots were taken about 5 minutes after I took the phone off airplane mode. Like I said in my previous post I'm still on stock, unrooted. In the last few weeks I already did a factory reset without any results... I hope someone can figure out what the problem is or how I could solve it myself!

Thanks in advance

Looks like mediaserver is scanning your sd card for media files... that or it misbihave from broken media file(mp3,mp4,avi,jpg, etc).

As far as battery life, I am extremely unhappy. From 7:30 hours screen on and whole day, now I get up to around 6 hours screen on... same usage, same applications, everything the same and with consistent result from 7:30 and even more to 6-6:20 hours. I am not the only one, there are a lot of people complaining from the battery life since updating to lollipop. Not sure if some apps misbehave on it or htc f*cked something that causes under certain conditions batt drain.

P.S. Stock, unrooted, tried twice hard reset.

[One (M8) General] xsardax:
Thank you! This have solved my problems. Lots of mp3 files were messed up, and obviously my other mp3 validation program couldn't identify these problems.

My ringtone music was affected also, now all is fixed, and will give it a try. Thank you.

I had the same issue. Now fixed all mp3 files, and will check again. Shouldn't be more than 0.1-0.3%/h in standby.
[One (M8) General] Henkhimself:
I may have been too early with my comment stating that the issue was fixed. At the moment I'm still having a drain on airplane mode ( and on idle for that matter) around 12-16%, even after the 4th factory reset. I contacted HTC about this and they offer me to send it for repair. Before I bite the bullet I want to do a battery test but I'm seriously considering just sending it for repair because I'm running out of options.

I've also checked for corrupted mp3's but found none. Which is obvious considering I did a factory reset to begin with.

Any advice would be appreciated. :)
[One (M8) General] navid0308:
What's draining your battery? One long shot is to do this

Turn off phone (if on kitkat make sure your fast boot in settings is unticked)

Plug into wall charger

Let it charge for 10 mins

Press and hold power+vol up+vol down for 3 minutes at least while charging

Phone will reboot several times

After 3 mins let it go and let it charge to full

This will reset the battery charging logic and MAY help your case.

It's a long shot. It has no side effects though, no loss of data or anything.
[One (M8) General] golf12:
I found GPS is the biggest killer for me with GPS off I get around 2 days but not much screen on time
[One (M8) General] xsardax:
Hm, it could be, but GPS, like BT or NFC do not consume power if not called by certain app. If some APP is messed up, it can call GPS constantly no matter if it is ON/OFF. That can cause severe drain.:cowboy:
[One (M8) General] Henkhimself:
Tried that aswell. Just to give you an idea of what I tried:

- Multiple factory resets

-Wiping the cache (through the fastbootmenu(or whatever that fancy menu is called)?)

-Formatting SD card ( both drain with and without the SD card)

-Resetting battery charging logic

-Checked for corrupted Mp3's (found none)

-I have Locations set to off

-I made sure that I turned off wifi and mobile data before switching to airplane mode

-Screen is set to the lowest setting possible

I'll charge the phone to 100% again and I'll post a screenshot tomorrow morning.

Thanks for the help :)

It's crappy lollipop

If you recheck at the start of this thread, I'm one of the few with a perfect battery life (as perfect as you can expect, in all scenarios). 0.5% drain being the norm.

But with lollipop, overnight, same everything... 1.7% drain per hour, sleeping, 17% over 10 hours

Compared to my usual 2-3% over 10 hours :/

System UI, Google Services and the Android OS shown as responsible

[One (M8) General] :
I am getting the same battery times and less than 0.5 percent drain per hour idle, same as kit Kat.

Now, I don't usually game. No social apps, though some Hangouts recently. And I keep Google now and location services off. In fact, I do everything I suggest in post 2 in the battery help thread in my signature.

So, I have to assume most Lollipop battery issues must be related to location services (no surprise), social apps, gaming and I realized as soon as I got this phone that I get FAR better screen time manually adjusting my brightness and keeping it as low as I can. (I use "display brightness" from playstore.

I bet one or more of those above things are causing issues, since I use none of them and my life is still phenomenon. ?

[One (M8) General] high_voltage:
This is simply not true. My use is the same as yours: no gps, no location services, google now off, no gaming, etc, etc, etc and with absolutely same usage as on kitkat, factory reset and even less apps: from 7:30 hours SOT and around 20hours battery life I am dropped to 6-6:30 hours and around 18-19 hours on battery. Android OS seems high + google play service, but I am not sure as I am not rooted right now(warranty and sh*t... but I don't know if I will resist a lot longer since I miss the freedom, tweaking, flashing, etc) and that limit my options to trace the problem on more low level. :/

[One (M8) General] :
But if you're not rooted, then you definitely don't have the same setup as me. ?

I've also froze about 15 or 20 or so system apps I don't need. I greenify certain things. I use Nova, blinkfeed is frozen. Again, manual brightness, huge difference for me anyway. Android device manager options disabled. All of them.

No doubt battery woes seem to be higher on Lollipop, not just for the m8, but many devices I follow. Just, whatever is causing it hasn't affected me. So whatever is the cause, or causes is something I don't use, or have frozen.

And here is a recent screen shot... And my average times, since October are at the bottom... And still consistent.

(other factors like radios, carrier firmware, signal.... Etc... Could be at play also)
[One (M8) General] Badelhas:
Anyone?
[One (M8) General] shiniyoyo:
It might be weird but I decided to take a different approach to this whole battery life thing.

First thing I did was uninstall gsam. Why? Because I found myself checking the damn app every few minutes instead of using my phone. I also took off the battery percentage off of the status bar. I focused on getting through a day or 2 of battery by using the phone smart and it truly helped. Without an app to tell me what I was doing, I found myself worrying less and less.

I also just used my phone smarter. I took off all apps I don't use, use chrome without the tabs on the taskswitcher, all that jazz. I use my wifi more often than my data and I turned my brightness down. I turned location to battery saving blah blah blah. What I did notice helped a bit was greenify. I hibernated ALL apps I don't regularly use or ones I don't really need notifications for.

But yeah, I went from worrying if I got 6 hours of screen time to using my phone in 2 days. It helped me, I don't know if it helped you guys out. Just thought I'd share :D
[One (M8) General] Callliope:
I'm kinda offtopic but it should be rule how you take screenshot, i cant get more than 4 hours sot, but with powersave i get lile 6,7 and my app usage in gsam is constantly at 70%

At first, i saw people with 60, 70 app usage and 7 on screen time without powersave enabled and i though.. My battery can t be so bad cuz without wakelocks i cant get that, then i activated powersave and i had same usage as them and same SOT, so don t look at your "neighbour" and see that he have higher SOT cuz it isnt relevant

On topic

I think i ll do the same, i m too obssesed about my helf awake time and SOT
[One (M8) General] Badelhas:
Thanks, but I was hoping someone analysed my screenshots and gave me some kind of clue if I had something sucking up my battery...
[One (M8) General] high_voltage:
True, true. I mostly mean that my usage didn't change(nor the place where I use the phone) in the transition and my batt life decreased. I am sure you are right that the more draining is under certain conditions as I see various reports from great to bad battery life.

8 avrg not, but before was easy to get 7:30+ hours SOT and 20+ hours on b. Also I have real screenshot with 12+ SOT :D (yep, chat with manual brightness and waiting for msgs for few hours, but also fb, msg, chrome, youtube, few short calls). My avrg was 7:10 SOT and 20h on battery. Now it's 6:15 and 19h.

I am not some prodigy, but I am using android devices from few years and also contributed to the development of few roms/kernels as a tester before public releases or special builds. I mean that I am not someone who make up things or doesnt know what disabling sys app is(yep, did that too).. or I hope I am not :D.

Also looks like the phone is charging a little bit slower with is reported from various users/rl friends of mine with M8 lollipop. Just a tad slower, nothing frustrating.

I am sure if I am rooted I can get a lot more of my phone(been there, done that.. a lot), but warranty can be issue and the new phones are just breaking fest. I drinked cold water with HOX from the first batches bringed to me from usa... wifi case/antena+microphone+digitizer = new screen on phone under warranty... in us. :D gived so much money... but was really good phone when rooted/custom kernel/rom/tweaked. I had 5:40h SOT(normal use) on it and most of the time around 4:30h woth for it was not bad and that with tweaked phone from me to be fast(edp on, but 1.5GHz max, ondemand gov, noop i/o scheduler,416MHz gpu).

Thanks for joining the discussion!

google play services possible fix

Thought a fresh start might help. Here's what I did

Sign out of Google from accounts n sync

Went to all apps

Cleared data for anything from Google

Restarted phone

Logged into Google again and started all sync

I've lost abt 10% since last full charge

Fb is my highest drainer cause of notifications

No sign of Google play services even though every possible Google feature is turned on

I'd gladly appreciate some testers!
[One (M8) General] th3:
If that's how you are like, then such a person needs to uninstall the app.

But not all of us are like that. You only refer to GSAM to test if you suspect something is not right, or after a major change.

I just went through a full charge of Lolliflop:

It's DEFINITELY higher power draining.

2.5hrs of Fifa, and the rest YouTube, Internet and Tapatalk.

8hr25m SOT

8hr55m active

13hr56m Total Battery

In the same setup and usage, KitKat achieved:

9hr SOT

10hr10m active

21hr50m Total Battery

So you could see from the above.

KitKat: 11hr40m standby

Lolliflop: 5hr standby

So the biggest difference was standby and idle (resting). This is a major regression.

More likely doesn't work well with sense/htc specific thing/some applications. I know on nexus phones it works better... dunno, but for sure the battery life is shorter, standby/idle drain more... and that sucks as if you read webpage the phone is basically idle many times and that kills even the screen on battery time moreover the standby drain that shorter the batt life even more. I am disappointed in that regards from lollipop... and battery life is crucial nowdays for a lot of us.
[One (M8) General] TwistyValhalla:

It's to define the level of maximum brightness when in auto mode (when under direct sunlight, for instance). What's your SOT? And what do you mean with "directly from the gallery", how does that work?
[One (M8) General] xsardax:
[MENTION=4791359]Badelhas[/MENTION], my SOT is actually very good, with 1 to 1.5 hrs of phone calls per day, I can get with no problems 5h SOT.

Problem that I have is drain in idle or standbay or overnight. I think I've resolved it, like I described in my previous post.

Thing that bothers me is WiFi issue, but it is not too big of a deal.

Why do you keep near max brightness all the time?

If you keep near max brightness AND 3G/4G data all the time, you're bound to max 5hr SOT.

Your screenshot shows 13% used in 2hr with 30min SOT. With that usage pattern, you'll get:

99/13= 7.6

7.6x0.5= 3.8hrs SOT (6.5hrs Active)

7.6x2hr= 15hrs Total Runtime

Indeed, looks like you have the same problem as everyone else: Major standby drain
