Battery Drain - One (M8) Q&A, Help & Troubleshooting

I restored my phone to stock marshmallow and I'm having a battery drain:cryingroblem, what can you help me with developers
?

I'm no developer. But what I can say, is that you haven't provided nearly enough info:
1) How did you restore to stock specifically, RUU or otherwise?
2) What are you restoring to stock from? A custom ROM? MM or otherwise? And you had normal battery behavior with that ROM?
3) How long have you been using the phone, after restoring to stock? The battery meter needs to "settle in" after you've done RUU or flashed the stock ROM. Meaning at least one power cycle from full charge, and drain to 10-20% to set the battery meter "high" and "low" flags.
4) You might try an app to see what is causing the most battery drain (some folks have mentioned Watchdog app, although I haven't used it personally). If we don't know what is causing the battery drain, all we can do is guess.

[Q] How to increase the battery life?

Hello Mates,
I am using Wildpuzzle ROM v0.8, which is having many problems in its stage.
The camera fails to operate sometimes. But I do managed to make it working using an external application.
The major issue remains of the BATTERY.
Its been a disaster for me to use it when EDGE 'on'. When the downloading is taking place, this phone starts draining the battery within 30sec for each percent. Presently i get the battery backup of around 120mins max on data usage.
One more issue lies in, the battery wont get charged beyond 71%. I need to reboot so that it shows somewhere more than 90%.
I have tried to reflash the v0.8 rom but facing similar problem again.
Will Radio update be a better option?
Can you recommend any better Sense Enabled Froyo?
Is this the bug in the ROM itself?
Help me, with your suggestions.
Thank You.
Recalibrate your battery. Just perform a search on XDA, there are many guides. It cant be a bug with WildPuzzle because I have personally tested it extensively, and this issue didnt exist.
Only after a fresh flash of a ROM, I get very bad battery life, but this is normal in all ROms I have tried. After 1-2 charge - discharge cycles, it fixes itself.
But because you are facing issues like it doesn't go beyond 71%, then jumps to 90% etc - Your battery definitely needs recalibration.

Gingerbread 2.3.4 huge battery sink!

Hello all. I just upgraded my HTC Merge from froyo 2.2 to gingerbread 2.3.4. I like how the new rom works, and feels and its features. But on froyo I would unplug before bed, with data off, wifi off, gps off, bluetooth off, and wake up with 99% battery life. I did a titanium backup before gingerbread. Updated with HTC Sync and used titanium backup to restore all my settings. Now when I wake up I have 37% battery!!!!
Going from 1% battery loss in 7 hours, to 70% battery loss in 7 hours is completely ridiculous. I have one a partition cache wipe, battery stat wipe and the like. I have not changed any settings. The phone is not in use over night. The stats show that android OS and system idle are both using 40% of my batter a piece. Any ideas? Could it be a bad install? Some say their battery life is better, how can mine be so much worse? I've tried most of what I've read from the thousands of other users with the same problem. I am rooted, but don't know of any custom roms or kernels for the Merge. I have a few more things to try, but just wanted to see what you guys all thought.
Thanks for the responses guys, I appreciate it.
Yea I had a similar issue that was fixed, for the most part, by changing the kernel. I guess you should try to find one custom for the Merge? Never heard of that model..

[Q] 28-35 mA Drain Issue

I'm at my wit's end here. There's no indicated partial wakelock by much of anything, but somehow my phone has a drain of around 30 mA when idle. It seems like this is off by something like a factor of 10 from what it should be.
Does anyone have a conclusive fix to this mysterious battery drain?
I'm on ARHD 6.1.2 w/ Revolution HD theme, with no applications that visibly are hogging CPU or partial wake locks, currently just wiped the entire phone and in the process of calibrating the battery, but for some reason it seems to be draining way too fast.
I'm not sure whether this is going to become an issue again, but I've always run into the problem every so often and a solution would be very much appreciated.
Are you using the recommended radio for that ROM? Radios make a big difference to battery life.
I assume you didn't do anything dodgy like restoring system data via Titanium Backup after you flashed your current ROM...
Also, you checked the MD5 of the ROM zip before flashing?
Is the drain constantly ~30mA when idle? does it ever reach the normal ~5mA it should when idle?
Check the drain in Airplane Mode to see if it's a Radio issue.
Flashed proper RIL for the radio I run, airplane mode is a steady 1 mA.
This has happened before, I'm not sure if it's the result of uncalibrated battery or just a bad ROM.
Currently calibrating on ARHD 6.1.2, seems mostly smooth sailing with <10 mA drain idle.
I run an Inspire so I use the latest GB radio/RIL released for the Inspire.

Battery drain even when arc is turned off

Hi
since a few time my arc s is draining battery in airplane mode at night (20-30%). I am using Arconium 3c.
- So I tried to come back to Arconium 2.4 (it was ok before) : the same (20-30%)
- So I tried to turn off the phone and the same : the battery lost about 20% during the night.
The battery drain used to be great in airplane mode (2-3% per night) few months ago when I started using arconium. So I don't think it is because of this rom.
Maybe my battery is bad? Or something else?
How old is the phone
In wich interval you recharg it
Check out the battery usage under settings and look if you have installed any program that uses much energy from ur battery
I think the easiest way is to try the other ROM first. If this problem still occur, maybe you have to check your battery
I also had that problem but with this stay good:
Use this kernel
http://forum.xda-developers.com/showthread.php?t=1680793
Use this Baseband
http://puu.sh/pAgX
Use this app https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU
For me is the best option
Well, thank for your answers. So the phone is 6 months old and I don't understand why if I change my ROM or my kernel it would do anything? Because the battery drain occurs even if my phone is off. Is there a way to check is my battery is damaged?
Tonight I will try to remove the battery for the night.
PS: I checked that I have no weird application that is draining battery...
jap check what happens if you put the battery out for a night
but you should even check the other kernel

Well, I am back to Arconium 2.4 (with .562 firmware) so the other kernel would not work correctly as it is for 4.1.B.0.431, would it?
I guess I should try .431 based kernel if I come back to Arconium 3c.
I have tried battery mix to check if there were an app draining my battery when phone is truned on but nothing (appart from system android) seem to consumes much battery.
Ok
well but if you really want to know what i think i would say (not assure) that it depends on the rom cus some time ago i had a2 different phones (galaxy spica and galaxy gio) wich i flashed to spicagenmod and the gio to cm7 and i recognized that the battery usage increased in a huge amount
u say that even if you turn of the phone it seems to be that you get a loss of power in your battery
the spica often crashed and i had to restart it (used many experimental features)and after the restart i had a huge los of batery power....
some roms have problems updating you the current battery status and if you restart it it seems that it had taken much battery
if you really want to safe power you may search for a undervolted kernel
Hope that really finished ur problem =)
Ok I think I understand what you mean about the voltage. ie at 100% the voltage is about 4178mv and now at 41% the voltage is 3775mv (with battery calibration app). So it seems to be not linear.
So I am going to flash kernel as recommended previously. And Do I have to reflash rom and baseband after flashing new kernel?
depends on wheather the kernel works with ur rom
what do you mean? I flash new kernel, reboot phone and if it does not work, I Reflash the rom? Maybe it risks to brick?

I dont think that there is any risk and thats what i meant flash kernel check if it works if not reflash rom =)
Download betterybatterystats and see what is causing the drain, think iridika did a thread a while ago, lemme find it for you
Edit: http://forum.xda-developers.com/showthread.php?t=1433309
Check what is causing the drain using that
I dont't think it would work when phoen is turned off..
And I am trying to flash kernel with flash tool and it does not seem to work, it is like I still got the previous kernel... any idea?
did u enter fastboot mode? did u get any error while flashing?
Yes, everything seems to work fine. Maybe I don't know where to check my kernel version.
go to settings..about phone...check about kernel.

Just an FYI
0% on the lithium battery is not 0v it is more like 3v or so... depends on the battery.
if a lithium battery measures 0v it is DEAD.

So I try this app and it appears that com.sonyericsson.android.server.dormant is guilty... about 2500 alarm wake up in 1h. so I used titanium backup to freeze fast dormancy...
But it does not solve my problem about battery drain when phone is turned off

As said earlier full charge the phone remove the battery and leave it out when you would normaly have it off to see if it is the battery or phone.

Abnormal Battery Levels

Hi, i'm running Paranoid Android 2.52 and since the last 5 days or so I've me experiencing the two following situations: the battery is fully charged, i start using the phone and it discharges normally, but when I load a heavier app it just shuts down suddenly with a low battery warning. the other situation is when i connect the phone to the wall charger after this issue, it starts charging normally but then it just jumps right to 100% with the same speed that it went down. Already checked the usage statistics but cant seem to find whats causing this, the battery just goes down abruptly.
Thoughts, anyone?
Try a different rom.. I recommend a Gingerbread rom with a kernel that supports battery calibration like Oxygen Rom. If there is no improvement after using the rom, calibrate the battery with this guide. http://forum.oxygen.im/viewtopic.php?id=723
If there is no difference, your battery is probably shot.
I've tried wiping the battery stats several times, re-flashing the rom, scripts and gapps, calibrating the battery and flashing rooted stock desire rom.
Is this method any diferent? I want to avoid moving to another rom if I can, i have tried several and i really like my current one.
EDIT: okey, I did as you suggested, flashed oxygen and followed the calibration steps. I was quite hard as the phone shut down as soon as the voltage level drop bellow 3201, but i managed. I experimented for a while on oxygen and the battery acted just the same as before. i have now reverted to jb, this time on AOKP v2.1. Is my battery ready for a replacement?
