[Q] Android system at 44% battery use @ ICS 4.0.3 , who else? - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
Since I started using Lite'ning ROM v2.1 I noticed that my battery was draining very fast.
I went to my battery use and I saw that "Android system"was using 44% of my battery. Wake time is almost 6 hours...
Is this a known bug or is there a solution to this?

Battery drain start with the Better Battery Stats app and thread .

If the rom you are using is not yet a fully stable rom then it could have battery drain problems, although battery drain is usally how you use your phone. Look what apps are running when you notice your battery running down fast, as it could be one of those.

When im at work i actually only use whatsapp, and sometimes facebook while im on break. But my WiFi is off all the time then, only whatsapp and battery monitor were active. With 2.3.4 this wasn't a problem and my battery would be 60% when i came home...

Either google wakelocks and how to pin-point them, or wipe and install NO apps afterwards, run it for a day and if the same problem go to another rom till it's more stable .
What works fine in 2.3.4 has no garuntee's that it will work an experimental ICS build of any sort.

i have similar problem. my galaxy is on wanamlite 9.6, which base on LP7. after 5 hours of not intensive using, i have 65% battery left, android OS use 68% of this battery, most of time my wi-fi is off. when is on, drain battery very fast, over night even up to 20%. when i was on ginger bread it took around 6% - 8% with data and wi-fi on.

Do you have many widgets?
Especially Beautiful Widgets and Fancy Widget (moreover if you activate the meteo forecast) will constantly drain your batter in search for your position. Wifi uses less juice than 3G connections.
Happened to me back at GB 2.3.4. Battery went down to 60% in 3 hours (at the office I'm on G...so even worse cuz the battery compensates for the lack of coverage). After I removed Fancy Widgets from the screen everything went back to normal.

Don't have any widgets as far as I know, only the clock and twitter...
Today battery is know at 26% after 11 hours on battery. Process stil at 39% battery use.
I searched the web and found that there are a lot of users having this problem, especially with the Google Nexus.

[Q] "Cell Standby" and "Phone Idle" are killing me!

Yes, another battery life thread but this one is a recent development for me.
I bought the phone on release day so I have some track record with it. I have not had any trouble with my battery life and have always been able to make the day on a charge. However, recently the Cell Standby and Phone Idle has been sucking my battery dry MUCH faster than in the past.
I unplugged my phone this morning and headed out to work as I do every day. I grabbed my phone at around 10am and saw that the battery was down to 58%. I checked that stats and this is what I saw:
Battery Level 58%
3h 46m 59s since unplugged
Cell Standby - 27%
Phone Idle - 20%
Display - 20%
Bluetooth - 11%
Android System 9%
Other stuff that was nominal >5%
Is this normal? Why would Cell Standby and Phone Idle suddenly be draining the battery when it didn't do it before?

More info on your rom? do you have Wifi calling APP? If you have a custom rom, did you do the battery recycle?
Thanks for the reply...
I am on the stock ROM (rooted). I am not ooposed to flashing a new ROM but I definitely don't want to DECREASE my battery life which is what I have seen occurs with some. Are any of the custom ROM's proven to increase battery life?
I don't have Wifi calling and I haven't done the battery recycle. I fell out of 'tweaker' mode a while back and have just been using the phone. I don't think I have even installed any apps since (or before) my battery life seemed to change. About the only thing different is the Market but I don't think that's a problem.
I just looked and it's down to 38% in 6h 24m and I haven't even touched it. It's rediculous. Something is like a parasite in my phone and I don't know what it is. The only thing running in the "Active Applications" is Launcher Pro but that was one of the first things I installed when I got the phone.

Nero V3 is great for battery life. Also check if you added some apps in the past few weeks. Might be some background sync process taking too much of battery life while in standby.
i've had this issue before and i've found that it was always a rogue app. your best bet is to start uninstalling or freeze them in titanium to find the one that is screwing you up.
one app that was my latest standby hog was beautiful widgets.
Thanks for the tips! I will start removing some apps and see if that helps.

I am not up to speed on the various ROMs. I will go start reading up but is Nero V3 fully functional (camera, GPS, etc.)? I was keeping track of the progress on all of the ROMs but there are now so many and they are updated so frequently it's tough to keep up (at least for me).
Thanks again!
Oops. Double post.
i'm sure it's an app that's causing that. I think a stock rom won't drain that too much.

[Q] 60 percent idle battery usage / 15 hours

I am having huge issues with my battery on my galaxy s2. It drains really fast, 60% over the last 15 hours this night when the phone has been idle. This has been an issue for about a week now; I cannot seem to find a solution? I have tried various roms, wiping and doing a clean install, but the problem continues. Currently using lightening rom 3,2.
Do anyone know what can be causing this battery drain? Is the battery defective??
What apps do you have installed?
Sent from my GT-I9100 using XDA App
That is quite a drain I can see there. The drain might be caused by having too many widgets or having too many applications open. If you plan to put it on standby, do close those apps that are not important to you.
Have you tried rebooting?
I have a stock lightening rom 3,2. no apps installed, except titanium backup pro and opera mobile. I have frozen all kinds of stuff in titanium to try find the cultprit, but without success. As you see, no apps except andoid OS is running. Same drain on villainrom, lightening. Don't know what can be causing the error. Is there some way to check if the phone or the battery it self is to blame?
Try with screen on - normally I think that should run for 6 hours or so. Using that as a reference, you can check to see if the energy stored in the battery is normal. It doesn't look like your OS is staying overly active to me.
Hi bjorninge,
Every time after you flash a new ROM you should calibrate your battery.
Get the app "battery calibration" from the market and follow instructions and please report back whether you can achieve better performance.
Cheers,

I have a similar issue, as was the same with my captivate. I have stock ROM on my GS2 though, the way I got it out of the box pretty much. Android OS takes up most of the battery usage. I don't know what it is. Widgets updating constantly? The constant syncing from Gmail/push email?
Well that's surprising! Awake and Screen On bar is quite low and totally synchronized, yet 60% drain, now I gotta say it's weird.

Unfortunately, I have the same issue as you've described above. I am running on stock KE2 kernel and the battery drain is quite a lot. The 'Android OS' is always consuming a lot of processor time on standby mode.
This needs to be fixed A.S.A.P.!
Download and install the app BetterBatteryStats from Android section, it is a very useful app which will show what Awaking the device from deep sleep and processes too. For me, it was the damn Latitude stuff going on background and wasn't letting the device to go to deep sleep.
Regards.
Sent from GT-I9100
Thanks for the tip. I have downloaded the app now. what spesifically should I look for?
You just look under 'Wakelocks' and you will know what apps are causing the Awake, then you could take further steps.
Regards.
Would be great if you could look at the screenshot and tell me if something is wrong. Also, after the battery calibration, I've "only" lost 26% the last 7 hours mostly idling. I don't see anything abnormal in the screenshot I provided :/
Well nothing is wrong imo as everything is very low. You should check those which are using more than 10 mins Wakelock, some seconds doesn't matter actually. And you can post any query further to the original thread of this app, here,
http://forum.xda-developers.com/showthread.php?t=1179809
Regards.
OK, So I'm now back to 12% battery usage (from 100% to 88%) with 17 hours and 30 mins on battery, which IMO is normal.
What did I do? Well, I removed the battery and put the rest of the phone into the stove for an hour on 50-60 degreed celsius. My 98% android OS usage is gone and the battery works as normal .I also had problems with the phone constantly going into "car mode" which is now gone.
I got some tips around the internet that my issues were all related to moisture on the inside of the phone.

[Q] S2 using 30% battery per night

I have a stock SGS2 with a lot of widgets running. I use BetterBatteryStats and have removed the high power usage apps.
Past few days, the phone uses a lot of battery at night. Yesterday it had 32% battery and when i woke up it was dead.
Are the rest of you also seeing this much battery consumption every night ?
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
I gave up with the stock S2. Rooted it and flashed MIUI to it along with the Siyah Kernel. Now it uses only 6% for the whole night. Battery usage is so much better now.
People having issues with battery should try the siyah kernel and change governors (unless some app was draining your battery)
yeah, actually some new users will experience battery problem. however, some says that when time goes by, the problem eventually sorted out itself.
i am guessing the phone need "warm up time"
I had the same problem with stock rom. you have to remove the preinstalled useless samsung apps. then battery consumption is better.
i am now on cm7. everything is working and around 8% per night with a lot of background processes (tasker, lbe, scheduled titanium backup).
Don't always turn on wifi or data unless necessary.Turn off background sync.This should help a lot even u r using stock rom.Kill tasks with built-in task manager.Make sure useless apps are not running in background.
With these tips,my s2 with rooted stock rom and stock kernel only consumed 3% of battery all night .
i keep wifi or gprs on for instant messaging needs. The Siyah kernel and the lulz governor give amazing battery life because process runs at lower clocks instead of jumping to 1200 unnecessarily.
The stock kernels aren't too bad in my experience.
I think you will find your battery drain will be caused by rogue apps before the kernel.
Edit: why have this phone if your going to turn off gsm and data etc. May aswel turn the phone right off and have zero drain overnight.
A drain of 1-3% per hour with everything turned on is normal for me.

Better Battery Life
In stock gingerbread I usually got 1 1/2 day of life with 2-3 hours of screen on. With CheckROM v6 I got around 2 days with 4 hours of screen on. Now with ICS and CF-root I got with the first full charge 1 1/2 day with 5:30 hours of screen on!
I froze all the junk that comes with the ROM, I only have a partial wakelock AudioOut_1 that is driving crazy. So far I'm quite happy with it.
Please search the forum we have so many Battery ICS threads already!
Battery life is def better with ICS, have you calibrated your battery since the update?

I'm not having any real battery issues myself, but since quite a few people report it I decided to call Samsung and ask if they will provide a rollback to 2.3.5 or what they could do to alleviate the issue.
And the answer was, as a technician had told, to solve the battery issue I should do the following:
1.) Charge the mobile to 100%
2.) Let the device drain battery as "normal" until around 9%
3.) Then open applications that drain battery fast until the phone shuts off
4.) With the phone in off-mode and drained recharge it to 100%, and do not turn on the phone at all during this time
5.) Turn on phone, and the battery life should be back to normal
Seriously, this was the official answer I got from Samsung support technician. Sounds like some old woman's advice, but hey if anyone with battery issue want to try then why not. At any rate it can't hurt

AOKP, ICS Battery life issues..

I've been using the latest gingerbread builds and I'm having great battery life, But I notice when I use AOKP or any kind of ICS rom my battery life isnt so great..
Is there a specific kernel you people are using? and What kernel settings are working the best for you?

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.
