Is there any solution to the battery drain on ics

i lose around 40 precent overnight everyday
its really frustrating knowing that i have to work with it full day afterwards
so is there any fix for this?

No idea what youre talking about. Mine only drains 20% with wifi and wifi apps running overnight.
Maybe you should look over what you got running, and if you got a custom kernel, reduce the lowest frequency of the cpu. Im running mine at 450Mhz or something.
Ooooor maybe 'overnight' for you is like 26h ?

You could also............

Leave it on the charger over nite! I know. Shocking.

Download "BetterBatteryStats" from here and check which app is causing it. If you need assistance, just head over to BBS thread. Remember to attach your log file so it's easier for them to help you.

First thing, you should get CPU Spy from the market. This will tell you if your TF is going into deep sleep or not.
If you were experiencing the same issue under HC then ICS most likely wouldn't fix the issue anyhow.
Prior to ICS I was loosing about 25% over night which just shouldn't happen. I was rooted but stock otherwise. I unrooted my TF & completely wiped before flashing ICS. One cool thing about ICS is there is an intergrated task manager widget. You can see what programs are running at any current time. There were three programs that were constantly running that I disabled. Those were PixWE, Netflicks, & My Uploads. Netflicks kept wanting me to update but I don't use it so why update it? I simply disabled it and there are a whole host of other programs that can be disabled too.
With all this being said I am only loosing 3-4 percent over night running ICS completely stock.

Try airplane mode
There's an app in the market that simulates airplane mode, but allows wifi still. After I installed it I stopped losing battery overnight. It's basically a wake-lock issue.

+1 This worked for me too but for a different reason. My TF tends to leave wifi switched on, even when told to turn off when the screen does. It could also be a rogue app as described above. Once you sort it out, overnight drain should only be a few percent at the most.

How to diagnose here
I lose ~20% overnight in flight mode.
If I go Settings > Battery I see it's a lot of Android OS. But widgets must be included in that. So then I go settings > apps > running and see a few apps running, but I can't tell which of these is killing the battery and I don't know which app would tell me ((can I run top on the the commandline?)). I will experiment more and report back. I suggest you do that same.
This should go in the first post of this thread:
To diagnose this charge before sleep, put into flight mode overnight and look in the morning to see if the Android OS has been the culprit.
Perhaps you don't need any 3rd party apps for diagnose but if you need to be available for early morning calls use a profile scheduler.

Get a new Kernel
The main problem is the kernel in ICS, a way to fix this is changing your kernel, I do recomend the Test kernel from Guevor, install from version 11 to up, test it and keep the one you like. My tf is lasting fully with keyboard, around 30hrs.

I use test 13
but on .17 and not .23

I'm on ICS 4.0.3 with 3.0.8-NEO though

My Nook got stolen and I'm waiting for a DroidPro to arrive so this would be on my main phone. When I've tried to flash just the kernel on it's own I've had problems before. This time I'll give it a go but am I missing something in terms of flashing a new kernel on?
I'm on ICS 4.0.3 with 3.0.8-NEO-3.0-TeamICSSGS-257174-g197c9a1-dirty (build *07)
Other than the possible battery problem it's been good. I just want to check to see if yo uhave anything more concrete to backup your decision... that a different kernel really might make any difference because that Test kernel from Guevor is very much in flux... I'd no idea which one to choose.Up to test15 now.
(thread for reference here: http://forum.xda-developers.com/showthread.php?t=1565519 )
For convienience it would be nice to backup the current kernel first as other than battery it's working well...
update, edit instead of bump:
ok, I lost 1% an hour last night in flight mode (6% over 5 hours) with all background apps and services killed. Does that seem about right? The interesting thing was that not all processes/services/backgrounded showed the same on different task killers...
I bet there's lots of people updating kernels when actually it's an app, or the left over effects of an app or something like that.

[Q] Help! Google app is draining my battery!

Hi guys,
In the last few days google app is draining my battery. It is disabled for wake up and keep awake in privacy mode, I tried to calibrate the battery, nothing helps. Even when I put it on flight mode, the draining is insane!
I attached screenshots.
My phone is not rooted, and I cannot root it.
Thank you all in advance!

I uninstalled it. I do not ise the cards and voice assitant plus I am an old fashioned guy, using search function in Chrome. By the way I saw other people having this issue, but don't know if it was resolved.

Yeah same for me, mine has been draining so fast when the phone is idle too! I'm running xnph05q cm11.

Uninstall the app update which is causing battery drain. Use it for some day using factory version of the app. If problem not resolved, report back here

For chrome, you can do the same thing as suggested above
Android OS and Android System.. You can't do anything with it.. If you play with them, you'll end up making your system malfunctioning..

So do you suggest to uninstall updates only for a few days and then update it again from Google play?
BTW I have another wiered thing, I am on battery saving, GPS is off, and when I go to battery usage, it shows GPS on...

Hi there,
Until I will have a report regarding your previous suggestion, can you please take a look at my screenshots and tell me why the GPS is always on when I am on battery saving all the time?
Something is draining my battery, I get only 2:30 SOT, in the best case, without games videos music or even phone calls.
Thanks a lot!

As you have not rooted your bacon, only thing I can suggest you is that with the help of Privacy Settings, disable access for wake up and keep awake for the apps which are not oftenly used and also Google Play Services
Battery saver mode disables background services of the apps and lowers done the device performance
Combination of above stuffs can help you increase your battery life to some extend
Your GPS is not always ON as seen from the chart

Android system severe battery drain 5.1.1

Sup XDA!
When I updated to android 5.1.1 (cm12.1, rooted) android system started to drain my battery, even more than my screen would. This wasn't an issue back on 5.0 and I wonder what the problem is, and I thought you guys could be able to help me out as this forum has helped me before, thx for that!
Ive attached 3 screens, first is from battery monitor and the other 2 are screens of my battery 'page' in settings. Let me know if you need any additional information and or screenshots and I'll be happy to provide.
Thanks in advance

Disable all of the google services you feel that take RAM (and so, battery) using the Disable Service app. Don't disable GCM Service. Don't disable FusedLocation Service if you use GPS. The only google service running on my phone is GCM. Disable location services, key chain, pppreferences, CM logger, dev tools, etc. just anything that you find isn't important and takes battery! Use apps like Greenify, Disable Service and Titanium backup to greenify, disable and freeze the apps/services.

This seems to be a common issue.... the fix involves downgrading the modem. However downgrading the modem requires downgrading your TWRP Recovery... which you cannot do if you are running CM12.1, the downgrade will fail every time no matter which "tricks" you use.

You don't need to downgrade TWRP to flash a modem. You can very easily flash a modem without TWRP even installed; fastboot. It isn't even certain that the modem is causing this drain either.

Working on the likely assumption that it is the same problem, the modem is indeed not to blame.
I have moved through COS12.1, CM12.1, sultan, paranoid android, and exodus, with and without flashing the modem and gapps, using both stock and Boeffla kernel.
They all exhibit the same drain, 9-11% overnight or 16-40mA/h (via dumpsys). This is regardless of wifi/cellular/ambient and other features being disabled.
The only obvious anomalies differing from 5.0.2 are high system_server cpu (25-450% via top) when asleep, and intermittent floods of "unknown" wakeups without wakelocks (Observed by dumping batterystats, and are not registered by settings - battery).
On one of my many reflashes Exodus 12.1 suddenly began behaving reasonably, with 6-10mA/h drain and 2% overnight.
The high System_sever cpu and intermittent wakeups were still present at this point, and may be unrelated oddities.
I later made the mistake of flashing a newer nightly (and later the correct modem), upon which the problem reappeared.
Doing a wipe and reflashing in the same manner did not resolve the issue, and many attempts later I have been unable to reproduce the same state.
Coming from kitkat I figured 5.0.2 would be the same, but it has been smooth sailing since flashing it last night (Exodus), with 6-10mA/h drain and 0% overnight.

So right now you are on the 5.0.2 exodus builds and having minimal battery drain? Which modem are you using?

Correct, with the Xposed Mobile Radio Active fix applied.
bacon_firmware_update_2015_04_03.zip from ... <10 posts and am not allowed to post links yet.
It's on Exodus' 5.0.2 download page along with the roms.
As usual the modem will not flash in TWRP, and has to be done manually via fastboot.

As you have tried many things to improve your battery life, last option I wanna suggest you to use your device in safe mode for one complete charge cycle from 94% down to 5% (I know that this mode is pathetic).
If you still find that it's causing battery drain, you need to reflash the ROM and please do not restore any backup(restore only those which are most important).
If you find that Android system is not causing anymore battery drain, then it's one of the third party app that is doing so.

Ive only tried to disable some services that show up under android system. How do I put it in safe mode tho?
By the way, I just noticed that the CPU total time for android system is exactly the same time as the SOT, what does this mean? It only drains this much battery when the screen is on?

Boot your device into safe mode https://support.google.com/nexus/answer/2852139?hl=en
Just post some screenshots of the battery (complete overview of graph screen and app list screen) after using your OPO in safe mode atleast for one charge cycle (90%+ down to 10%)
This will help us to figure out what is the exact issue you are facing.
If you are not interested in troubleshooting, just flash fastboot images of this build(CMOS12.1) using following guide

For OnePlus One, about a month ago after systems update, my battery started draining fats and it has gotten worse over the past week. The battery barely holds four hours of after a full charge and the phone gets very hot. Also, over the past week, my main SMS messaging app (SMS) crashes nine out of 10 times -- I can start the app but when I click any of the messages I was to read or type, it freezes and crashes. Also, since yesterday, my phone dilaer crashes very often. Any thoughts/help? I am not familiar with how to flash ROM, etc. Also, since yesterday, charging has been very slow -- overnight, the charge went from 35% full to 74% full. I tried safe mode as well and no luck -- battery still keeps draining at 1% every three minutes.

I have the same issue. Any fixes which work ?

Battery drain (Google account manager)

Let me start off by saying I was so happy with this phone and its battery life but the past couple of days I've seen it drain more than usual. Upon checking I see that Google account manager is responsible for this.
Anyone have an idea what caused this? and how to fix it?

i noticed the same on my chinese mate 9 however the % is below 40 still, from what I can see on my case is the google photos app causing all the noise I had disable synching over cellular data but haven't seen any improvement so far. I did that 2 days ago

Same here on my P10.
How many Google Accounts do you guys have linked? I currently have 4.

Thx for your replies guys!
Meanwhile I accidentally found out that this might be the process what is on other phones the Google Play Services.
I tapped on the Google Account Manager entry and scrolled down to the bottom of the next view and there it is..
Still I haven't seen the "Googl Account Manager" process ever before I assume that Huawei handles or at least displays the processes differently than others (at least Samsung) do.
For me it's a good thing since I see way more processes sucking battery than my SGS7 showed me.
Remembering the battery drain on my SGS7 the Google Play Services had pretty similar battery drain like the "mother process" Google Account Manager has on my P10.
So I think that's it
What do you guys think?

I have the same problem, lot's of times it's a Google calendar fail sync or Google fit fail sync because the system close it and when Google account has do a sync that's impossible because the apps are closed so I'm testing to not force closing Google apps. I will tell you my results

Still shouldn't use that much. Literally it's the most used one. One hour of screen use today and I'm down 25%
My Huawei watch is the only thing connected. No autosync no nothing. Used it minimally. My note 5 after last update and a reset lost maybe 6% all day. Android OS n kernel aren't an option. It's not on 7.0 tho

Does anyone have a solution for this? It is horrible since a few weeks (no update in the meantime, no other apps installed): Google Play Services (Google Account Manager) are very active, device gets hot, reboot helps for a short time, but almost every day I have a huge battery drain. Before the last weeks, this was not a problem at all, battery usage was super.

Do you have developer options enabled?
I've had the same problem, after diasabling developer options it seems to be somewhat better but not really cured.
I also enabled in settings the automatic memory and data cleanup as I've found that cleaning all app caches helped for a short period of time.

I fixed my by doing factory reset. Now everything is back to normal.
Also before I had a problem that whatsapp didn't show messages if I didn't open up the app. This issue also got fixed the same time.

I'm suddenly having high consumption by media server - have no idea what it means and the phone is quite hot.

mediaserver can be due to listening or streaming music, or indexing music.
its fairly normal, however if your rooted you can disable it in an init.d script.

ive still got issues with android os using the most power. i only get 6-7 hours max screen time. i use my huawei watch via BT. latest update for the USA 183

Seems to be getting worse. Now I'm slated max 27 hours. WTF

in reality battery life never gets better. The constant discharge, and charge rates only put wear and tear on the battery. It would great to have the ability to swap batteries on the fly.

Android 9 rollaback to 8 because of battery drain

Hi!

Any tips how to go back to Oreo without losing data?
Please help
thanks

Are You sure some app doesn't crash in the background or something? Since Pie, I get 12-15 hour SOT every day. And I have Google AOD on all the time.
Maybe download Matlog from Play Store and check if there's anything crashing. Just look at the live logcat for like 10 seconds and if You see new messages popping up every second(like a lot of them) then take a screenshot.
From what I've seen, most people get around 8 hour SOT on Pie.
Don't give up just yet .
Edit: and I'm not sure if it's possible to go back to Oreo without wiping data. Most stuff would probably crash a lot.

Theres unfortunately no way to rollback to Oreo without a complete wipe. Oreo has July Security patch, whereas Pie has september one. So you HAVE to clear all contents of your phone, otherwise it will be encrypted due to security reasons.

Do You have root? If not, then You can use adb logcat on Your PC. But if it's too difficult, then You can download GSam Battery Monitor and it should tell You if any app is draining Your battery.
