***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.
Samerhing happens to me... and I just took it off the charger and I'm on 96 percent in less than 1 min

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.
Sent from my Fascinate using the XDA app
I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

try disabling gps in the notifications, that worked for me, but once i turn gps on again, it will drive up to a high percentage.
As far as I know, this bug is related to gingerbread and not by samsung, somehow it is triggered randomly (some say google maps, others say wifi or games) and the root cause is unknown, that's why some people haven't experience it, a quick temp solution is to restart the device but this is just terrible solution..if you are affected pls help spread the word so the issue becomes a high priority in google, the issue is already raised here since Feb 2011 and a lot of people have already experienced it (I myself experienced it):
http: / / code.google.com/p/android/issues/detail?id=15057
but it is still under medium priority, unbelievable! do you remember the SMS bug? google got pressured when it was spread in forums and news site..I think we can do the same here..let's raid android forums and android news site
here's the thread detailing the bug:

Hi mate,
I used madmack's ROM which is based KE7 to enable Arabic.
What does factory reset means? will I loose all this setup? also how do you do the reset?
What would be my options if I want to keep madmack's ROM?
Kind regards,

The battery on my UK Vodafone supplied SGS2 doesn't last long.
The battery usage shows the following:
1) Android OS 54%
2) Email 20% (I have an exchange account)
3) Display 12%
4) Cell standby 5%
3) The rest is divided up as Phone idle and Android System
This is after just over 11hours of it being turned on, with a 3G, no wi-fi, gps or bluetooth, and the battery is nearly drained.
Does anyone know what type of usage accounts for 'Android OS'. I have no idea why it uses so much of my battery. I don't use the phone that much, i'm not playing with apps and fiddling.
The 3G signal is for my Vodafone Sure Signal. Since it's local to my house, the transmit and receive power is very low, far less than if I were outdoors with a 3G signal.
I wondered if the various types of Sync's that are performed in the background are what's accounting for 'Android OS'.
I've turned off the live wallpaper now to see if that improves things, just in case that wallpaper keeps cycling even though the screen is off.
I'm not getting the monstrous drains some are reporting, but still a solid 21% of Android OS plus 5% of Android System (whatever the difference is there). I can't remember exactly if my Hero had the same amount, but I think it was lower than that.
Got the drain. A factory reset fixed the problem, and I'm gradually re-enabling services and accounts now.
Just enabled my second Google account now, and the results are a bit worrying. I'll post back when I know.
How can you find out the battery usage??? I can't find it anywhere on my SGS2, I want to know too
Sorry, I've found it...
Mine is (without sim card, wifi on)
Android OS : 16%
Display : 14%
Android system : 3%
Phone idle : 2 %
Cell standby 65%
Yep I get it. Maybe we could start a poll?
For anyone else experiencing this battery drain: Factory reset helped A LOT. Doesn't seem to matter much which sleep policy I have for Wifi either, and all my Google accounts are added now. Will be re-connecting some more accounts and changing some settings gradually over the next days. I'll post back if I find anything that breaks my newfound battery life.

What's the point of doing a factory reset then loading up all the same stuff you had on it last time which will eventually lead you to the same problem?

I'm asking my own too.
i had the same problem as Madcow29 my cell standby is 70% without sim and wifi on. 22 hours and the battery was emty
hi iguys,
i have some questions about the sgs 2
i got it since a few weeks and everything was fine,great battery life up to 17 hours zith light/ normal use.
i tried to flash cwm isecure kernel to flash roms, all went fine
then i found out rom manager is not yet fully compatible with sgs2
so i flashed back to stock firmware,now my battery life really sucks
with little use i can hardly get 6 or 7 hours out of it
and most of the time its just standby
i have everything off bluetooth,gps,wifi, display set to 10 percent, background sync
the only thing i have on is 3g connection..
i have better battery stats installed
and i see these 2 things always 100 percent full.
suspend/events
no matter what, theres no app draining because when i wipe everything to factory settings or through recovery, the drain remains, even with 3g off
also when i check my normal battery history,
i see 2 times android system in the stats, doesnt one need to say android os ? instead of two times system?
sorry if this is a double post, but i searched and couldnt find something similar then this.
hope you can help

You have BBS installed, good. Don't see under Processes but see under Partial Wakelocks, check which apps and processes are taking the max time. Something on background is definitely going on.

thanks for the reply, i checked and only facebookservice,rilj,mailserver,activitymanager have a smal redd line
and all are under 2/3 percent
the rest dont even have a red line going, today i swapped my battery at the store, but i dont see any difference, yet, just draining
Nobody else here to help me ?
better battery stats shows me nothing like an app or process
thats really going crazy..
i really have no clue what i did wrong to get this terrible battery life
hmm i really don't get why though, coz I have an awesome battery life with my S2, i got at least 2 days, with alot of calls n txts in between. I use it for my music player in the car as well, n i travel quite alot.
tried recalibrating the batter?

yes i tried, i also tried to wipe battery bin file through cwm, also with no succes,
my phone is charging now, so i am going to check how the battery life is with CM7 or another rom.
do you have 3g on all the time ?
i also have a question about the connections options, do you have an option to only use 2g ? in stock rom, i dont, i remember having it on my galaxy mini
Update, the new battery i got yesterday seem to have no change in my dramatic battery life,
i flashed CM7 build 38 last night,
and still the same, it drains like hell!

wifi sharing is not using any power on my phone
also with better battery stats, i dont see nothing unusual in the stats,
also on top of that i have watchdog task manager installed, i never get any notification from any app going crazy
i almost never use wifi because i have 3g and unlimited internet every month,
sometimes i use the gps, when im done with it turn it off
i cannot get a normal 8-9 hours with normal use,
mostly doing some facebook checking, sending some texts, a little bit of ping, checking the weather..
And im not sure what to do. I need some advice because I just cant find the issue! This morning was the final straw, my phone was at 100% charged and all i did was take about a 3 hour nap woke up to an over heated phone and the battery at 10%. WTH?? I use cpu spy and juice defender and nothing. I barely have any apps other than a wellsfargo one and 3g watchdog. Im running [ROM]<=TASK650's ICS'd OUT! V5 right now and i just switched over from cm7 because i thought maybe that would've been the problem? I dont know if its a deep sleep issue because ill look over at it sometimes and the screen just turns on out of nowhere and ill have to press the sleep button for it to turn back off. It also like to randomly turn off as it please. AHH THE FRUSTRATION .
Anyway enough rant can someone help? Or at least give some advice on what I should try or do? Thanks.
Your screenshots are inconsistent with your stated behavior... Loss of 20-30%/hour and an overheated phone says the thing is stuck at 1200 MHz and full load - but your CPUSpy graph shows only 9% at 1200, and a total of maybe 40-50 minutes since reset.
Also the battery graph in your first shot has a major discontinuity... It drops from 100% to 10% instantly. I've seen glitches of 20-30% jumps at a time after a fuel gauge reset, but never anything like that.
So then what your saying is I should kill it with fire and then return it and grab another one? lol I dont know anyone else with this type of situation. Im not just one to go and ask a question because im too lazy to search. I swear i looked and googled EVERYWHERE for some type of solution but i just haven't found someone with this type of problem.
as Entropy mentioned, that jump in the first screenshot makes no sense. You should probably recalibrate the fuel gauge.
Looking at the 2nd screenshot, a lack of deep sleep seems to be the culprit. You'll need to track down what's keeping your phone awake. I've read something about exporting the wakelock log but perhaps there's already an app for that...
Also, clicking on the graph (in the first SS) will show you a more detailed burn down which might help isolate the issue.
Lastly, did you change kernels as well?
Im sorry im fairly new at this. It just has the kernel that the rom came with. I recalibrated the fuel gauge like you said and retook some screen shots that ill just leave here. It keeps over heating and Shutting off on me every half hour or so. On top of that The battery just drains in a mater of 3 to 4 hours. I think the problem is just the phone itself. Im going to try and put the original stock rom on it later this week when i have time (Finals are driving me crazy) and then Im going to try and send it back and get another one. I might need a usb jig thingy tho. Its very frustrating this phone isn't even a month old and like i said before i googled for a full hour and a half and I just couldnt find a solution to this.
mmmk this just happened.
That certainly doesn't look normal. When it takes those sharp dives is the phone rebooting? Also when you flashed your new ROM did you wipe all data in cwm first?

Suggest running better battery stats from a full charge and when you get that instant drop go into bbs look at partial wake locks.
Also have you done any

Ok Ill definitely give that a try the moment I have a chance and report back here the results. I haven't done any oc/uc either. Thank you guys for taking the time to help me figure this out.
I would try a CWM Backup. Then Factory Reset, Cache Wipe. Then install a fresh copy of Task v6. If that doesn't fix it, restore back to your backup you did.
I was having fun with undervolting myself (would crash my phone). Every battery pull I did, I lost 20-50% battery life. JUST turning the phone back on! Though in my case the phone would stick at this percentage for a long time, then when it caught up, eventually draining. I would assume the battery was not calibrated, but people keep telling me "this battery does not need calibration" (Whatever).
It seemed to fix itself for me though, after letting it drain down a bit more. I let it fully charge this time with the official wall charger. This was with Task & Siyah. Has not happened since.
I hope your battery works itself out!

kk so I'd guess your battery really isn't that low, it's just reading low after those reboots. For whatever reason sometimes the phone will show a significant loss after a reboot, but really didn't lose that much. However something still isn't rite obviously. I'd suggest redownloading your ROM and clearing/wiping everything in CWM. And do a fresh install. Someone might be better able to help, but if I was getting random power downs that's probably what I'd try. (I might be wrong, but I don't see how wakelocks would be causing it to power down)

Thanks for the input everyone. I just got back from class now and my phones dead no surprise there but Im gonna let it charge back up and ill repost some screen shots of cpu spy and betterbatterystats since i just got that running on the phone. Afterwards Im going to try to just wipe everything on cwm reinstall a rom and see what happens from there. I bought a usb jig that should be coming in by the end of the week just in case all else fails and i'll just send it to att and have them ship me a new one. Thanks for all the feedback you guys are awesome!
OH I forgot to mention I dont think the phone actually shuts off because I was talking on it for a bit but i was talking through my bluetooth headset. I went to check if i had a text message and the screen wouldn't power on but I was still able to talk on the phone WTF? Makes no sense to me.
Really starting to wonder if your CPU has voltages it can't handle...
ok been running shostock2 since 2.2. Absolutely love the rom for it's simplicity. However a week or so go I updated to 2.6 and my battery life went to hell. I then reverted back to a previous backup 2.4 and my battery life is still hell.
I was at a full charge at 5:30am this morning. Now at almost 1pm I'm down to 38 percent. All i've done is sent a few texts, no voice, no updates no nothing. I did manually flash the cherry picker kernel after upgrading to 2.6 since i wasn't sure if it was packed with the latest revision.
Not sure if it's the kernel or a setting or ?
Sync is off, GPS is off, Wifi is off, bluetooth etc. Have good signal etc. Screen times out at 15 seconds and is on auto setting
Battery stats shows Android OS eating 31% screen 28% Exchange at 16% cell stanbdy 8% phone idle 6 e-mail 5% android system 4% phone 2%
Not sure why exchange is sapping so much since it's set to manual updates.
Just not really sure what to try. I did let it go fully dead, gave it a full charge, wiped battery stats first thing this morning.
I did try power saver for a day and it made zero difference.
Any help on how to get my battery life back to normal or other advice in this situation would be appreciated.
Question,
are you using Go launcher? and go products by any chance?
no stock Apex launcher. Like I said it was running great then all of sudden blamo it all went to hell.
Now one detail which may make sense to someone smarter than me(most of you). When I tried restoring back to 2.4 on saturday I was at around 65% battery. When I restored back to my CWM backup to 2.4 my battery went instantly to less than 20% which I found really weird as well and never seen any rom change do that.
