Android OS 80% Drain - Galaxy S II Q&A, Help & Troubleshooting

please explain this crap. i am on Slim ICS with Siyah Kernal 3.2.1. Korean S2 converted to I9100. for 3 days m getting this Stats. no matter what i do. it always come to this. I Delete the Battery Stats from Kernal menu. but after some time. ths Android OS again shows the same.

so 30% batt gone in 4 an half hr apprx..so u mean ur not using an this happens give rom,kernel details an more in depth will ,giv u better ans

First read the What is Android OS post second read and install from Better Battery Stats thread .
jje

Yes I did not use it. and my in 4 hours 30% discharge. m using Slim ICS with Siyah kernal and Yes i had read that post about android OS. there's no way Android OS drain can be that much.
Is this a Korean Version fault?

and my problem is not related to better Battery thread. or it is? please guide me

give it some time to settle and install betterbatterystats so u can kno if anything is causing wakelocks,,,,,also wat i suggest is turn brightness to lowest,auto sync off,no livewallpaper,use data only wen needed,enable power saving mode,turn off wifi,bt,don use live widgets,avoid task killers, hope this helps to a point....and using totally black back grnd helps alot in tecky way...

Wait about 3 recharges and check what your drainage is then, if the problem still occurs, try reinstalling the ROM. Hopefully, the problem should be fixed.

No, the intelligent ones take the advice to use BetterBatteryStats. The others just moan about it and make fail threads.

I had this issue on every phone running ICS 4.0.3, even on nexus s and I found out that it is the bug in OS, it's a false reading. But if you really experience battery drain try to reflash and use clean rom for a couple of days and see if it's still present. I hope I helped you, cheers

No, you don't have to change rom unless the rom is draining battery, and you can check that by reflashing it and use it clean for a couple of days. I have stock i9100 ics 4.0.3 and battery stats are reading android os as one of the top consumers but I don't have any drain. I guess it's a 4.0.3 bug because I had same reading on nexus s with stock 4.0.3 and on various stock/custom ics roms on different devices.
Sent from my PMP5080B using XDA

I just found out that this bug can be fixed if you disable screen touch and lock sounds in settings>sound. Apparently this keeps os awake. I've disabled all sounds except ringer and notification on my devices and now I'm testing that theory, I hope it will cure that bug and maybe give me some extra battery life.

You realize this is not normal, and trying to fix is stupid in my opinion, waste of time, I'm have used aosp and cm9 and stock and all are way low.

maybe it's stupid, maybe it's not, but when I see that something is wrong i try to fix it, and as far I can see turning those sounds is working, my awake time is now only 15-20 min longer than screen time on both my devices. Before I did that it was 2-3 hours longer on a daily basis. I think he should try, and if it works, great, if it doesn't he should change the rom. Not really waste of time as he can test that in couple of hours. Cheers

[Q] PROBLEM SGS2 eats battery incredibly fast

Hello!
My sgs2 battery lasts for 5-6 hours
Im not using it that much. I play games for 30mins and thats all. I don't use it all time.
I was thinking that battery is broken so i bought another but 2000mah and it didnt help too but lasts one more hour . Im really worried.
I have mA usage widget and it sometimes shows 600mA 300mA screen off 200mA.
I've frozen all unnecesary apps.
I have kernel siyah 2.6.7
Can someone help me?
Check for wakelocks.

Brilliant. Carry on enjoying your 5-6 hour battery life then.
very funny
It will help also have you checked what is consuming battery? Do you have data, wifi or bluetooth on?
Sent from my sgs2 running cm9 using xda app
Yes I checked everything. I have wifi bt 3g off, screen 40% in battery usage it says screen eats 70% battery and the rest is some apps 2-3%
You were given a way to possibly increase battery life from Oinky, and you dismissed what he said with "Thanks but I don't think it will help" ?
You're obviously an idiot then. And frankly, you don't deserve help at all after that.
Do you realise BetterBatteryStats is probably the best way to nail down wakelocks that can chew thru battery, once you've taken a look at the really obvious stuff ?
Clearly not.
"Some apps".
Very helpful. These apps don't have a name then? Too lazy to type them? You think we should guess?
You don't seem to want any help.You definitely don't deserve any.
Best keep your charger handy.
1. Are u using a task killer..if so don't
2. Are u rommed? It could be that theres one on x10 that ate my battery n am on a 2.6k mAh.
3. Ur kernel.. if its oc cud be a problem.
Turn mobile data, backgroud data, auto-sync and of couse your brightness, can save battery, if all this fails i suggest seeing your phone provider about it
Xperia x10i
DonutHD
DoomKernel v6
Unlocked and unbranded.. Bye bye vodafone
I would give you some help on it but I don't think you will think that would help.

Check for wakelocks, change your modem, try a different kernel if rooted, try a new rom if rooted, don't use any task killers.

Cyanogenmod 9 Battery Drain

Hello guys. I have installed cyanogenmod9 with Siyah kernel on my galaxy s2 and I already got one problem. The battery drains very fast.. I got no 3g/wifi/gps/bluetooth activated, no live wallpapers, just 3 homescreens with minimum of widgets, no applications running in background and I set the max freq for the cpu to be 1000MHZ.. And it still drains very fast..
These are the exactly files i got on my phone:
Siyah-v3.0rc1-CWM
cm-9-20120330-ODIN-galaxys2.tar
Could you please help me fix this?
Cheers!
Install BetterBatteryStats, let the phone run for 8-10 hours (use it normally or let it run overnight; whenever you're seeing the drain basically). Then have a look at the BetterBatteryStats thread on here.
This will enable you to pin down any wakelocks which are chewing thru your CPU (If it is indeed wakelocks causing the drain). If necessary, you might be able to post some screenshots/info to that thread & maybe the guys who post there regularly can give you some help with it.
Edit to add - For starters, personally speaking, I'd update to the latest CM9 nightly while you're at it (09/04). They're always making little improvements/changes.
thank you very much! i have installed that program, now I will do how you said and then I will post some screenshots in the thread. Thanks!
No probs If you find you do have wakelocks/post to the BBS thread & you don't get a response after a day or so, post the details here & I'm sure people will be able to help.

I would strongly suggest using Siyah v3.0.1Beta1
http://www.gokhanmoral.com/gm/
and dont usee that build of CM9 as that is the Resurrection edition. Download the latest CM9 from here:
http://download.cyanogenmod.com/?device=galaxys2
0904 is the latest.
make sure your wipe cache and dalvik cache.
put on cm9 first, then Siyah, then wipe, reboot.

Ok, i installed the rom that toxic gived here and when i try to boot the second room the telefon freezes. I need to take the battery off...
I installed it in recover mode from external_sd, along with siyah kernel and gapps..

u cant compare it immediately...
please go ahead with a calibration of the batt and after recharging once/twice compare the battery usage with ur current bad usage
make sure u cancel the useless options that suck up the battery, there's a thread regarding this as well, it helps trust me...
Which is exactly why I gave you a simple (possible) solution in the first instance.
Which you were obviously too impatient to try given it involved installing an app, letting it run for half a day or so then reading a thread on here/posting some info to that thread to get some answers.
Installing a new rom was overkill. If you weren't prepared to go down the BBS path with your existing setup, you only needed to flash the latest CM9 nightly, do a clear cache/Dalvik & again let it go for a day or so to see if that fixed things. And then you could have done the BBS thing with the latest CM9 nightly installed if necessary.
believe me i didnt want to install a second rom.. i just wanted to replace the old one..
i will do the thing with batterystats and then i will revive this thread and tell you the "news".
Thanks for everything.
no wakelock overnight. the battery dropped just 1 percent.. i am using it for 20 mins. 3 sms, 3 mins of talking and 3 mins of wireless. in 20 mins the battery dropped from 99 to 95 now.
OK looks normal/ similar to my usage in that amount of time... keep on testing, good luck

Are you talking about some kind of notification when you receive a message? This phone doesn't have a notification LED. So you need either BLN + a kernel that supports it, or install the NoLED app. Either one will affect your battery performance though.
When you receive a message, on every phone, the screen wakes up. Mine doesnt, do you understand what i am saying?
Thanks for the reply!

[Solved] Battery drops after abnormal shut down?

Hi,
My battery drops after every abnormal shut down, by pressing the power button for ~8 second. (I do this when the phone freeze.)
And when I turn my SGS2 on, some battery "disappear", sometimes 10%, sometimes 20%, or ever 50%.
For example, I have 90% of battery right before I shut it down (abnormal shut down) , and maybe I get only 50% of battery after I turn the phone on. It that possible that the battery drains 40% in 1 minute? Or it is normal because I shut it down improperly? (have a look of the attachment)
There is no problem if I reboot it normally.
I have two battery, having the same problem.
I face this issue in many ROMs, stock GB ROM, AOKP ROM, MIUI, etc.
I'm using Siyah Kernel 3.1.2 now.
Thanks for any help
(Sorry for my bad English)
I've heard a few users mention this battery drop and i've experienced it myself. It even happens sometimes if i restart my phone after flashing a mod or something.
You'll notice that the battery level starts to climb back up to where it left of (less the normal usage discharge)
Yep, normal on the SGS2.
Just part of the battery weirdness as a result of that fuel gauge chip. Entropy512 has written many a post on the subject if you feel like searching/reading up on it. Nothing to be alarmed about tho, and nothing you can fix. Just make sure you've got plenty of battery left before you do a flash.
On other hand, your freezes if regular is a worry!

Yup, my SGS2 freezes quite frequently after upgrading to Android 4.0.4.
Maybe I'll downgrade to 4.0.3, or perform a full wipe and flash the ROM again to fix this.

Battery drop is pretty common say 7 out of 10 times if you remove battery, after boot you will be 10-20 percent less. Specially if you change roms quickly..

[Q] Battery problem on Omega v47 rom

Hello to all,
after having a stock i9300 for 11 months (I never kept stock for such a long period of time) I decide to install a custom rom.
After reading a lot I noticed that the most popular rom for the S3 i9300 is the omega so I followed that route.
I intalled the latest 4.1.2 version yesterday and today I was surprised to noticed that the battery lasted less than 14 hours.
I did a clean installation wiping cache/delvik etc.
This performance is horrible compared to stock.
I could easily make a whole day regardless of usage.
1. Are all roms as bad?
2. Will a possible change of the kernel provide a solution is so which one?
Other than that the rom looks great with some added features from the 4.2.2 which look great and fresh.
But I can not accept the phone not easily go through a day.
I also noticed some issues with Skype (not the latest version as this did not work well even on stock).
thank you
p.s. I could not post to the omega rom due to the fact I am new here......

You are being judgmental.
I spend several days reading the forum and educating myself.
I did read in the omega topic that some people experience battery problems.
Some of them reported that a different kernel provides better battery life.
I did not notice though that after flashing a rom you need several cycles for the battery to be calibrated.
Furthermore, in most roms I read about there are several people (not all) complaining about battery life.
This is why I asked if all custom roms increase performance while decreasing the battery life.

I also used Omega once but the battery life was just like yours.
Try doing the following:
1. Download greenify, understand how it works and greenify your apps.
2. Install startup manager, disable useless apps.
3. Disable wifi settings such as "notify me for new networks". Also, while in sleep mode, make sure the option is set to never.
4. Put auto brightness on.
5. Disable sync.
You can go ahead and install a different kernel. Googy or Devil or siyah would be a great choise.
All of these should improve your battery life.
Thank you for your reply.
Out of curiosity why does this rom consumes more power since it does not over clock the cpu?

They are many factors that affecting your battery life.Everyone have different angle viewing things. So depend on them what a good battery life mean to them. You can try other rom though. I'm using foxhound 2.5 with googy max kernel. It bring a good perfomance for me. And you can try to buy a 3200mah battery for your S3 with original size xD It can last more longer. And try the comment above it should improve the battery alot.
well I always try not to leave wifi on when not in use and do not run programs that use battery resources. I do never use mobile data and gps is always off. I did install greenify but there was really nothing running on the background.
Still I am under the impression that the stock rom provides signifficantly better battery life.
So my question is why? (Only out of curiosity).

[Q] What's up with my battery?

I've heard varying reports of how long peoples' batteries last, anywhere from 9 hours to 3 days. But what seems to be the common theme is that if you use your phone pretty frequently, you'll get maybe 10 hrs, but if you use the phone sporadically and not for long periods of time, you can expect the phone to last through the day and even maybe the next. But with mine I've found that the battery on average will last me maybe 10 hours, but that's with slight to almost no use. From what people have said online, the screen is what sucks up battery, but when I check with GSam Battery Monitor, my screen never seems to break 30% of my battery use. Apps are what usually take up ~45% of my battery. What's up with this? I don't wanna have to buy that stupid Mugen case, because it apparently sucks, but there are literally no other options to extend my battery... any advice? Will post screenshots. Thanks!

Also, as you can see, the individual app %'s don't add up to the huge number that Apps is taking up... is that related/significant?

It looks normal to me. Usually the people that are saying they get good battery life are the ones that are on a custom Rom and a custom kernel. From my findings the stock Rom especially with the net updates battery life seems to be worse with each update. One really good combination I have run that yields amazing battery life is CM11 and crpalmers kernel. That combination will give amazing battery life. It also depends on what you use your phone for. Judging by your screen shots thing look pretty normal. I would try giving battery guru a go in the market of you want to get some more juice. Let it learn your habits and it will help with you battery life.
You also have to remember as the device ages and you recharge the battery you can't expect it to remain fantastic like the first day you got it. Like anything else they wear down over time and can only go through so many charging cycles.
Or it may just be your battery starting to go bad. Its hard to pin point what may be wrong. It may be as simple as a rogue app. Try some of the suggestions I mentioned above and post back to let us know how your doing. If your not rubbing a custom Rom I recommend switching to one. They are packed with features and the battery life is generally better.
Anyways good luck. Post back if you have any more questions.

100% agree. Especially with the updates leading to worse battery life.
I recently switched to the DNA from an S4. Unlocked and S off'd. Flashed 4.4.2 Rom and immediately noticed how awful battery was in comparison to my Samsung. I actually flashed an older jellybean Rom with Sense 4+ and now I'm experiencing battery life as good as my S4, even though the S4 has a larger battery and newer hardware.

Thanks for the info guys i'll keep that stuff in mind. I've tried several times to S-Off and flash a custom ROM but every time I try, firewater or rumrunner or whatever im using that time always says 'connection failed.' I've been unable to find any fix for why it's failing, so i've kind of given up. Any chance you guys can link to any super simple instructions?
Like I honestly don't understand temproot and those things. thanks!

In general there is a thread titled "am I too late to root" where I tried to explain the process to another poster the best I can.
couldn't hurt to give it a read. Maybe it will help you.

Getting a little stuck... Did the Weaksauce part, and downloaded the firewater file... what do I do now? I copied firewater to my SD card, what command window do I use? I really don't get exactly what to do...

I really don't know how to explain it any better than I did in that thread. On page 2, I wrote a complete step by step..the file goes into your sdk folder and then you run the command while in fast boot..I posted links and all in that thread. I don't know how to help further.
