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.

Did u follow all of the procedure to install cm9 ?
I'm quite sure u did something wrong, I managed to flash it right the noob way and updated to the latest build.
I'm getting amazing battery life with 3g/data/sync on all the time 1.5 to 2 days from 100 to 1%
Re-do it the right way and Cal the battery, hope that helps with getting started... if u still can't get a day from ur phone come back here and I'll help as much as possible... Good luck

Thanks for every advice guys.
Mazroui can you present me a tutorial with the "noob way"? )
I will update the rom and kernel with those that toxic presented me.
I have installed 2 roms on the telephone now. How do I wipe the bad one(the first one)?
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..
Could you tell me how to wipe it and install just one good rom on my phone?
Thanks for the suggestion, ill take a look at that thread as well.

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!

And I was saying that this phone does not do this by default, out of the box, unless you do one of the two things I mentioned above.
Do YOU understand what I'M saying?

Use your phone less and/or plug it in.
P.S. If you think this is a vague response, I think your request for help was vague. When you go to the doctor and tell him/her you have a pain, what happens next?
And there are umpteen posts on this topic already ffs

totally agree with ZACQ8
You can get a 2450mah battery that doesnt need a different case. Also try Android Assistant, you can view processes that are running and sort by cpu usage. Try to remove or atleast kill from startup any apps that do not need to run all the time. Most battery assistant programs do not work as after killing an app it will just load back up a few minutes later.
I got the official 2000 mAh battery which did give 15% more life. However the most effective improvement I got was from using the SpeedMod kernel and using Tasker to be more precise about when things came on.
Went from around 14 hrs stock to 30+ hrs for SpeedMod on stock rom for GB.

Hi,
To avoid too fast draining, some classics advices are to turn off some functionalities when you not need it, by example Auto Sync. Many applications needs to be configured with less frequent synchronization (weather apps or widgets, email apps, news apps...)
And as it was mentionned, some kernels can dramatically improve your experience. I agree that Speedmod is one of the best kernel to preserve battery. You can flash it easilly via CWM.

i'm already using siyah kernel 3.2 beta2 and i got audible touch etc turned off, gps is turned off too
I haven't looked at your stats, but I do know since I am on d4 rom as well there is some battery drain. Its mostly down to the kernel though, and not the developers fault (normally)
I recommend you upgrade to siyah 3.2b6 which has been serving me just fine with around 3.5 hours screen time.
Edit: oh and I see you had no signal for awhile, that drains a lot of battery.

Hi, I recently just installed a custom rom (donuthd) on my x10i and I'm currently liking it. One thing I noticed is that the battery drains too fast. I keep data and WIFI off most of the time. Is there anything about this that I can do?

Hello,

Hello, I also had a battery problem with a ROM, FXP CM9 has this case.
As stated THeLogiC it may be a problem with the DeepSleep.
I invite you to look at this message I posted some time ago about my battery problem.

Thanks for your quick replies. It seems I have a locked bootloader and so far, based on my some posts here, I read that I could use doomkernel. Are there any other choices aside from this? I'm using stock kernel by the way.

Hi, I'm also using DountHD ROM and the battery life is fine. I think You have some of the process running, that uses to much power. Try to check battery usage information, in case You won't find any of apps, give e a list of running apps. I hope I will be able to help You. There are some battery draining apps. Think in the past, have You noticed big battery usage after installing some of the apps?
Hi everyone. Thank you for your replies. I installed CPU Spy and my phone does go to deep sleep. I also checked for running processes and found some which I could not close. After a quick reboot, all seems well. Thanks again everyone.
@jakuburban Offtopic question. Do you use Fera or Th settings? I used Ferasettings and restart and recovery does not work.
I'm using settings that come with ICS theme for DonutHD(don't know what You exactly mean?). Try to use flashtool and reflash xRecovery. It should work fine. I know also some other way, but this is if flashtool method wouldn't work.

Hi All,
Does somebody has problems with the battery on Disaster V.8 ROM? I tried this very smooth ROM also with the Jeboo kernel included in the ROM, then the Jeboo 1.3, and now I'm on Philz v.4.22. Also I have tried Siyah kernel v.1.8.9 but it doesn't worked at all, installation aborted (error message: status 7)
On first Jeboo kernel the battery drain was very fast, about 9-10 hours, a little bit better 12-14 hour on the Jeboo1.3.
On Philz is better, about 20 hours. Maybe I have to set something on my phone or try another kernel, some suggestions maybe? :good:
I know there are a few apk's which can increase the battery life, but I'm searching for a good and finally solution.
BTW, when I was on Disaster ROM v.6 I have no problem with the battery life.

Unfortunately I didn't find a good solution, I read on the Disaster thread that this issue was also mentioned by a few Disaster user.
One of the solution is to change kernel which I already done, so still waiting for an answer maybe from Mirko (the Disaster developer) itself.
Or I will wait for the v.9 maybe the problem will be fixed with that kernel.
Anyway thanks for your answer.

My battery is good enough, with other ROM's I don't have such a battery drain.
But I'm now on the new Disaster ROM v.9 with the Jeboo1.3 kernel and I'm checking the time, update to come.
