i'VE BEEN RUNNING CM7 for a month (about)
I update to the latest version and right now im on the KANGED version thats not OFFICIAL release but it is made by the dev.
Anyways...
Every day i wake up in the morning, from 100% my battery goes to about 90- 85% from using it then i go to school, phone in my pocket for about 7-8 hours.
It usually goes to 70% or 75% when i check soon as school is over.... but today.. it was at 32%!!?
My battery has been draining FAST this past week. IDK what's causing it, but i think its a app, but watchdog lite doesn't show anything at all.
Any tips at all guys?
- PLEASE DO NOT REPLY TELLING ME TO PUT IT ON AIRPLANE MODE WHILE IN MY POCKET- I GET TEXTS FROM MY BROTHER/MOM TELLING ME IF I HAVE TO WALK OR IF THEIR GOING TO PICK ME UP AND OTHER IMPORTANT INFO LIKE THAT-
Please help me out here.
I love CM7, and it's NEVER been this bad, but if it is because of CM7 then i have no choice but to go back to 2.2.1
EXTRA INFO:
I don't have a data plan so... my phone can't communicate with other servers and crap.
I keep wifi off, bluetooth off GPS off.
Maybe i'll have auto brightness on but thats it.
Check what profile are you using on setcpu? Also you might wanna check the signal while in you school.

Check battery stats it will tell you what is using your battery the most.

I suspected it was SetCPU doing this, so i uninstalled that.
the signal is... okay? When in my pocket it sometimes goes to NO Signal, but is usually at 2-3 bars.

It says Android OS is using the most.
Then Display
then Cell Standby
then Phone Idle.
Honestly, my phone isn't even turned on during the whole thing..............
I maybe check the time once in the while, but besides that its always idle.
I just slept for a hour. I lost 10% in that hour. WTF is this lol
try recalibrating the batter by using either root explorer or the terminal to delete /data/system/battstats.bin as sometimes CWM on cm7 for galaxy s doesn't delete it.
i have the same issues and tried everything..i dnt even have data plan to use internet and i keep my 2g on and my battery still drains like pipes in the sewers

I use battery calibrator app and used it alot and battery left app shows, my readings are accurate but not from 0% because I never reach 0%.
Time to go to 0.
Thanks.
More tips would be nice as well

try not using the battery claibrator app, and removing it from your phone and manually deleting the batterystats.bin file from /data/system and see if that helps your phone at all.
I also suggest getting CPUSpy from the market, and track what states your phone is in and for how long it is in certain states. if it's not going into the sleep state, then something is keeping the cpu active (possibly a governor setting).

That aint normal my friend, you should jump into another modem, regardless of what you're on. Maybe that helps and by all means, what kernel are you on?
I'm on the stock kernel... Should I visage and can you link me to more cm7 modems or atleast a good one that works good?

During the whole night its been at 800ghz for 71%

Also how do I know its a governor setting? I don't usually use those at all
Where can I check if it was that?

The stock one should be battery efficient but I honestly haven't really tried it out. Give r12 or r25 a shot from here. They've been great in every aspect to me. Just make sure you're not on kang 7.1 when flashing, it doesn't support that.
As for modems I'd suggest either KB5 or KB1. If you're on either one switch to the other, may help.
don't run phone on "performance" -- it's silly to run the cpu at top speed when the phone is just sitting doing nothing. Run it at "on demand" or "conservative" especially if it is OCed. Also set screen timeout at a minute or less. If you got the phone used, it's possible the battery is old. If you reboot it a lot and install roms and stuff you'll run the battery down fast.
Well..
Yesterday I did a cleaning of apps i never use and some i installed recently.
I guess that did the trick? I have no more problems came back from school and my battery's at 76%
@Abu, thanks for the tips. i don't want to get a different kernel and modem.. im on kanged 7.1 lol.
@Nazcalito
Fearing it was that i uninstalled SetCPU.
Should i re-get it and make it OnDemand?

don't use setcpu if you don't have to. the built int scaler for the kernel is actually much better than letting setcpu run in the background polling the cpu and system for changes.
if you're running a custom kernel, get voltage control, and with it you can UV, OC, under clock, and change scheduler.
And in Settings -> CM Settings -> Performance -> CPU Settings, you can control min frequency, max frequency, and governors.

Hi guys,
So for the past week or so, I've been noticing really bad battery drain on my GS2, and I think I have finally pinpointed the problem.
"BetterBatteryStats" has told me that there are 2 specific wakelocks running in the background, which prevent the phone from going to 'deep-sleep'. These are the "suspend" and "events/0" processes. They are on for hours, preventing the phone from going into a proper 'deep-sleep', and keeping it awake.
My question is, how would I stop these processes from running? I know for a fact that it is not such a common 'bug', because tons of people are getting >18 hours on their GS2 with moderate/heavy use, while I'm only getting about 10 with light/moderate usage.
So in short, why are the "suspend" and "events/0" processes running while the phone is supposed to be in sleep mode, and how do I stop them from running and draining battery?
Thanks everyone!
Well I don't have that problem so can't say. You should ask it on the BBS dedicated thread,

This is the famous "Android OS" bug, which happens only on SGS2. Search the forum and you'll see quite a few threads about it. There is no solution, but keeping wifi off when not in use or setting is to sleep when screen is off helps quite a bit.

It's not only a bug on SGS2. I've been fighting this problem for quite a while on my Nook Color with CM7. Here's the thread I started.
hmm, I am having this problem as well, I'm used to my iphone, where i can use it all day and still remain above 50% meanwhile every time i pop the screen on my GS2 the percentage is down from last time. its horrible, very much considering going back, I love this phone, but this battery draining situation is out of control for me.. midnight -8:30 i lost 45 percent battery.. screen off..

well for me, installing the siyah 1.8 kernel has sorted it and my battery life is pretty damn good now.
Others will tell you its not fixed and the extra battery life im getting is a placebo. But all i know is i used to get 3 hours screen on time and lose 15-20% battery overnight. Now i lose 2% overnight and get 5-6 hours screen on time. If thats placebo then so be it.

hmm, ok, I will look into kernels, I am using an AT&T SGS2 so its a little different kernel wise. I have yet to find anything in my specific forums though.. just switched from an eperimental kernel to a stable, so maybe this will help
I think I just read somewhere in the Galaxy S2 forum that AOS isn't exactly solved on the .14 kernel (which siyah 1.8 is based on)..... it just merely not include suspend and events/0 into the Android OS count for the battery.....
Anyone can shed some light on this?

is siyah 1.8 better for battery life compared to siyah 2.1 or the newer one?
I tried 2.1, but I still have high android OS.
Using bbs, I see that suspend and events/0 is still around 1 to 3 minutes each day.
I have turned off:
Accounts and sync > background data & auto-sync,
Privacy > back up my data,
Location and sec > use wireless networks.
Any other advice?

Use a 2.3.4/2.3.5 based ROM such as CheckROM HD or Hyperdroid-Androidmeda with Darknight-Siyah Kernel.
I get 3 days of use if i keep data off . With Data on and normal usage i get on average 0.7-1% drop per hour compared to 3-4% of 2.3.3 ROM.I think it's a combination of kernel and ROM that solves the problem.
Earlier CPU Spy used to show lots of time spent at 800Mhz which is what android OS bug does. Now i see it spending 1-2% time in 800Mhz and most of time in deep sleep.
thanks for the reply.
now I am using CRv3.1.1 with speedmod 18test3.
but it seems that from day to day, events/0 & suspend are getting bigger and bigger.
do you know why?
I upgraded to KI3 a long time ago, and froze the hubs + wifi sharing / wifi sharing manager (i never even used the hubs anyways), and what do you know; my battery can now easily last me a LONG time, after 16 hours it still always has AT LEAST 40% remaining, and that is with a few hours screen-on time, data sometimes on, wifi usually always on! I'm extremely happy now!
So in short, for those of you with bad battery life, the least you could do is upgrade to XXKI3 or XXKI4 (they're pretty much the same thing) firmware/kernel. Even completely stock without root/frozen apps is A LOT better than any other 2.3.4 / 2.3.3 ROMs.
CRv3.1.1 is already based on xxkj3, and I have already frozen most of samsung bloatware.
However, I have just found out that kernel is an important factor in high suspends and events/0.
Now I use the previous version: speedmod 17 test 1, and suspends & events/0 decrease a lot.
After experiencing extremely bad battery life and searching everywhere around the web for answers i have found a solution for wakelock problems that solved all my battery woes.
Thanks goes to the people that originally found these fixes.
This step stops the AudioOut_1 partial wakelock bug from keeping device in awake mode:
0.go to settings > sound and turn off touch sounds and screen lock sounds
These steps stop the kernel wakelock 100% problem:
1.turn on aeroplane mode
2.turn off device
3.take out battery for 10 seconds
4.turn on device
5.wait for everything to load
6.turn off aeroplane mode

For starters,I tried everything else I could and this is the only thing that helped.
I found the fixes all around different forums for GS2,GNote and GNexus.
I tried it for myself yesterday and my battery life has doubled.
Install BetterBatteryStats from the thread on XDA and you can see if you have these wakelock problems,look under Partial Wakelock and Kernel Wakelock.
I just wanted to share these dead simple steps to spare some people from the agony that is 7h battery life :banghead:

Nice info. Might come in handy someday. Thanks for sharing.
sent from my fingers to your face.
there is another trick to disable apps sync or the famous ! CALENDAR sync wake ups go in "account and sync'' and click on your account and uncheck what you want to stop sync!
for facebook wake ups the only thing I found is freezing it with titanium and make sure your disconnected from it every time you quit this app
HOP FOR A FIX FROM FACEBOOK SOON !
for the rest I don't think we can make something unless sammy release the source and finally an official ICS !

I asked how did you find those steps because in my old days of Motorola Motoronga MotoFAIL Milestone (TM) there were a bunch of Black Magic Recipes like this in order to save battery and none of them worked, unsurprisingly, of course.
Please, don't get me wrong, I'm not here to troll you or your thread, but just to know how people find these "steps".
Anyway, very interesting.
Thanks.
Regards.
These fixes will help your battery only if you have wakelock problems,they don't do anything otherwise.
I also resent black magic recipes. Some time ago I read that many common battery saving apps and tips don't help the battery,sometimes even causing more battery drain.It was an independent research where they regularly tested the battery itself with ampermeters.

usually turning off touch sounds and screen lock sounds should solve the "AudioOut_1" problem, at least it worked for me

You neet to find out which wakelock are draining your battery when the screen is off before you trying out some "Black Magic Recipes".For instance ,if you installed some instant message app which keeps pulling something from the server and prevent your phone from going to deep sleep, disabling sound will not help you get better battery life.

I had issues with reboots and poor battery life after upgrade. I went back to gingerbread and done factory reset. Once booted I immediately went to kies and upgraded to uk ics. I have no issues now with reboots or battery. Very happy now and speed is great. Remember to factory reset in gingerbread and not ics. Just reinstall apps from the play store after.

Thanks!! It worked for me when my Galaxy Note was running ICS and now again when I have downgraded to GB.
CPU Spy showed 200 Hz to be the lowest state touched and there was no Deep Sleep. After these steps, it goes to Deep Sleep when not used.
I flashed CM9 on my GSII on Friday and ever since it's had 5-6 hours on usage. I've tried doing the battery calibration stuff, seemed to be better Monday and today it had 50% after a few hours of gaming so that seemed normal but then i reset it and it dropped down to 10%. I tried calibrating again and still 5 hours.
I've been using that Battery Calibration app and it game me 40% charge at ~3500mV. I'm not sure whether that is the battery volume but seeing as 100% was 4200mV something seems wrong.
Anyone have any ideas?

maybe the kernel makes the difference.-

I have an LG GT540 as well with ICS on it and that would get 8 hours regular usage with it. My GS2 get's less then that without me using it.

But I´m still test the slim rom with neal kernel and have 53% battery after 30hs. with a general purpose.-
try it this rom an kernel,.-
As was already pointed out, bad battery life is almost always a rogue app keeping the phone awake, install Better Battery Stats and CPU Spy to monitor wake locks and deep sleep, if you find a problem with an app keeping your phone awake, uninstall it and your problem will likely go away. Personally, I've been running CM9 and other variants of ICS for months and I get less than 1% per hour of drain while the screen is off and the phone is asleep, this is better than Gingerbread was.

Right, but background sync can still hit the battery, even with screen off. I was just curious.
Ive had days with horrible drain but it was almost always an app doing something dumb and keeping the phone awake, bad cell reception or a noisy wifi router. The trick being to identify wake locks that seem suspicious and track them down.

Go into system settings > Battery and check what is using most battery.
If it's screen there's not much to do other than leave auto brightness on.
The phone does use a lot of juice when it's on though, undervolting and underclocking might help a bit...
download cpu spy and betterbattrrystats
1 double check your phone is going into deep sleep when u switch of screen
2 use betterbatterystats to find out what's using all ur juice ( disable all the things u can ie sync mobile data etc)
3 have u overlooked or undervolted
4 what is your max cpu freq set at.
5 once you've found rogue app remember to uninstall betterybatterystats otherwise it will eat your battery ( learnt from experience )
hope this helps

1 cpu spy tells who how long in each freq sTate your phone has been

2 hmm dunno then

the deep sleep has the most of the time. so as the 144MHz, about 1 hour, and the 200MHz, 1:24 hours.
how can I check what app uses the most of the 1400MHz and the 200Mhz???
It could be media scanner. Sometimes it get's stuck and keeps on running. You can download rescan media from playstore and disable it.

thx, will try it.
now i have flashed the BLFB and updated it to the latest software, no root. now, in "cpu spy" the deep sleep is shown as "Unused CPU states" and the 1400 MHz is taking 61%. is this normal?

I get a battery drain problem. when the screen is off, the battery drain is normal, but when i'm using my phone, no matter what I do, it drain 1% per 2 min(I think). And I'm not sure, but I think I have this problem on any Leak or Stock i'm on... ! what do I do?

Ouch! That's a bit lot. I just flashed DL1 2 days ago and all is much better than in previous (ROM 4.0.4 BLG8). Since morning(6:30AM) down to 72% now(2:50PM).
How do I actually use betterybatterystats to find the rogue wakelock app? I'm very interested in this but don't know what to do.

Not really. I'm a newbie myself so sorry mate.
You could post your better battery stats on its thread. People there usually analyze it for you.
But basically your looking for apps with high time and /or count.
Each count represents that app going out of deep sleep for a microsecond or less. So an app with a high count will be constantly waking up your phone even if it's total time is only a few seconds.

Try to use watchdow to see wichs apps/process/system process are using most of your cpu, ma xcpu freq (1400mhz) shouldn't be that high so maybe a rogue app is draining your battery
If you want to see the wakelocks i recomend using GSam battery monitor, in the app sucker you can see wich apps are waking your device an how many times, but you have to try out after a period of time
The other problem could be some corrupted media files that make your mediaserver drain a lot of battery, if so, check the .nomedia files in your sd, look for image not loading in the gallery, use an mp3 checker app to se if some of your music files are corrupted (search through xda, someano posted an utility to do this) and try to re-encode your mp3, in my case, this solved my issue
hope it helps

it could be a whole bunch of things, people won't be able to help if you don't post any info of your device rom/kernel, wifi on? gps on? screen brightness? all that needs to be taken into consideration.
The most common problems for battery drain are media scanner as mentioned earlier, Google maps, wifi is a big drainer even if you are IDLE for some reason wifi keeps on receiving something (i'm guessing it is the "keep alive" packet) but havent dug into it, also found that "Samsung push Service" was sucking juice so I froze the bugger, the last thing I found on my S3 (runing Wanam's leaked JB DLH4) was "DRM Protected content" for some reason it kept coming up so I froze the sucker with Titanium backup and i'm doing around 20 to 21 hours average.
I've used Better Battery Stats, Battery Drain Analyzer and Android's own battery analyzer to keep track of my usage.
I hope anything of this helps you and good luck on your findings.
