***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.

NOTE: I did edit his post to make it a little more clear. I'm slightly anal retentive that way.
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.
I just flashed a new ROM this morning. I have had my phone unhooked from the computer for 3 hours now. I am now down to 79% battery left. Is this normal? Is there a way to make it better??

yea dont charge it until its anywhere between 5 and 1% so it can properly charge.
and dont take it off while it charging back up because you could mess up the cycle.
I only plug it in to charge at night and in the morning, I unplug it. I do not know what % I am at at night. I figure this way I will have all day without having to plug it in. Should I wait to plug it in when it gets to about 5%?
That's not normal, but more info would be helpful. Like what rom, kernel, modem? Do you gave gps enabled? Background data enabled? Brightness settings? Wifi on? Email/gmail check frequency? All things I would check first...
I just flashed Trigger v2.5 and the mod for an accurate battery. Everything else is the same I have used with other ROMs. I only have to fetching my gmail and freetext. My brightness is set as low as possible. WIFI is off. GPS only used every half hour for my clock/weather wiget.
Hmm. That's the same one I flashed this morning too. Right now mines charging, but I do know if I surf the net, my battery will drain fast (normal). Did you run trigger 21 or 211 so you have something to compare? The reason why I ask is because Ka7 will go through battery life VERY fast. KB1 which was in trigger 2.1.1 was a little better. My favorite for battery life is still JL5. Try running the phone with data off and weather off. See what happens. Try the older version of trigger, but first... maybe it was the battery mod? Maybe reflash without that mod then test. All things I would be trying if it were my phone. However I know from experience that I have drained 70% battery in about one hour using 3g KA7.
Can't I just flash KB1??
You can but keep in mind the KA7 in 2.5 is voodooed.
I am new to all of this stuff. I do not know what that mean?
KA7 has voodoo lagfix because people complained that kb1 was causing launcher pro to hesitate. In the thread they talk about flashing kb1 back but to disable the lagfix. Personally, I have flashed several different modems and not had to worry about that. Let me see if there is info in that thread...

Yea plug it in when its at 5%
and try flashing a different modem, they really have an effect on battery drain because they effect how your device connects to the network.
Go here and pick a modem for your firmware: http://forum.xda-developers.com/showthread.php?t=868774
Kernals make a big difference to, search the dev forums for them.

If I am not mistaken, I am currently using KB1, as long as the baseband version of T959UVKB1 means I am using KB1 modem.
You're right. I went back and reread the thread. Then I would narrow it down to either something running in the background or you just might need to do the "reset" for the battery. Lots of info on that.
So...I take it I was right on what modem I am on?!?!? Also, what do you mean by "Reset of the battery"?
In recovery mode, wipe battery status. There is a procedure to do it right though. Run a quick search for it. Yeah its ka7 kernel, modem is kb1. The lag fix is relevent for the kernel, sorry for the confusion.

First of all dude, how about take in consideration whats using the power of the battery then decide on whats right and whats wrong.
First of all even if you followed those steps on that link you posted, none of it matters because theres different kernals and modems that effect battery life, not to mention the ROMs themselves.
My advice come from many sources here at xda that say you should actually let your phone get that low and then charge it back up to get it at a complete charge.
and you know what it actually works!!
After i do that with every flash my battery turns out pretty great.
So Mr so know alot, u should feel really dumb for your non-thoughtful post

You can check your modem by going to settings/About then scroll down until you see baseband:
Your modem = Last 3 characters
Ex. KA7
And kernal version should be right under that.

So ive seen time and time again that the fuel gauge can be a little wonky on this device, and forgive me if I overlooked it, but Ive never seen anyone post a fix. The issue Im having is that when the full charge notification sounds and I take my phone off the charger, its usually at 96% and I have to plug it back up about 6 more times after the full charge notification for it to read 100%. Ive tried charging it while the phone is off. And clearing battery stats even though I know that doesnt matter on the i777. Is there anyway to fix this?

Our fuel gauge doesn't require calibration, so no need to wait a few days. Sometimes it's just a little bit off, it's actually pretty common for it to drop to 99 or 98 after pulling a charger (especially if the battery was deeply discharged before charging on AC).
96 is a bit low though... I know gokhanmoral was screwing with charge termination recently. That might be the cause.
The only reason I flashed Siyah is that I didnt like Neo's tweaked version that is installed with Illusion-xT. Entropy, your kernel will work with his ROM? Im not using the I9100 Hellraise. Im using his I777 port.
It should work. Hellraiser originally started with a kernel and modem swap.
The other changes (audio libs, keymaps) have to be done regardless of kernel.
You can think of it as "pre-hellraised" with a different I777 kernel.
Awesome. So Im gonna flash your kernel and report back on how it works and if my fuel gauge quits being an ass.
Entropy, your kernel seems to help with battery more than Siyah did. However, did not resolve the fuel gauge problem. Full charge notification went off and when I pulled the charger it was 97. Even after plugging it back up twice it stayed at 97 after it was pulled.

Now, this has happened twice in the last week. I unplug the phone from my charger and place it under my pillow for the alarm to wake me up, and go to sleep. I disable both data and wifi so that twitter won't update and wake me up prematurely. Then, I oversleep about two hours, and what wakes me up is the phone that's EXTREMELY hot. The alarm doesn't go off and the battery is completely drained.
I have no idea what drained the battery and why the phone was that hot (I couldn't hold the phone for more than two seconds before I started experiencing pain). I've tried searching, but there were no topics like this one. So does anyone know how I can fix this?

Thanks for the answer, but even after doing everything there I have the same problem.
A few days ago, I was able to "intercept" the process.
I had just used the phone, and put it away. Then after no more than ten minutes, I noticed it getting extremely hot. When I tried unlocking the screen, the phone had frozen, so I had to pull out the battery to turn it off. When I put the battery back in again and turned it on, the battery level was down from around 80% to around 60%. The battery graph showed like vertical drop, so it was clear that it had happened within those 10 minutes.
Is there really noone who has had this problem before?

Try N.E.A.K ICS kernel. I had some really good results with aokp rom. It's compatible with Samsung rom as well I think. Check it out
Sent from my GT-I9100 using Tapatalk 2 Beta-5
I'd be more worried about it setting my pillow alight
Steps.you could try:
- Wipe all data (Optional maybe an app conflicting with something)
- Update kernel or change rom to CM9 or any other stock
- If none of those work try an different battery
*I believe its an well wakelock had this when i was using siyah 3.1 Rc 1-5*
~Blizz™;
I had roughly the same problem. I did a full wipe and installed a custom from and changed the kernel... everything works perfect then. One of my friends finds taking his battery out every few days works best. Try both and see what results you get.

I would have to guess that it's either the kernel or the battery calibration. Are you using a third party battery? I think with the original samsung batteries, this must not be as much of a problem (I have never owned an original samsung battery for my S2, sadly). I know that with my fake Chinese super-cheap "2150mah" battery, which somehow is small enough to fit in the original cover which makes me think it's more like 1350mah, I have gotten horrible battery drain problems for basically no reason. But, after following the thread where it was explained to charge to 100% and then take the battery out, wait three minutes, and put it back in, I've had the phone stay at 100% for over four hours, with wifi, syncing, and all that turned on.
I should mention that I sometimes also have had this problem where it seems to be charged, then for some reason it drops to 20%.
If your battery is third party, make sure you calibrate it. I've also noticed that the more roms I flash, the worse my battery life is, so I'm trying to resist the temptation of flashing something new every twenty minutes.
Good luck.
/proc/last_kmsg
Use it.
You could try downloading Better Battery Stats and hope to identify the wakelock or app that's draining the battery. If it's not either of those and you haven't always had an issue with it under your pillow, I'd say it's time to try a wipe and new rom and if the problem persists even after that...hardware problem.
Have you been able to leave it under the pillow previously? Part of me is wondering if the overheating itself is affecting the battery and causing it to degrade though I doubt it should happen so quickly and in such an odd fashion as you're experiencing.
After a bit more tinkering and testing, I'm almost 100% certain that it's the kernel, as it was the only thing "constant" in my testing. I reflashed over and over. I also think it has something to do with the wifi, since when wifi's off, my phone is fine and doesn't get touched by the described bug. So right now, I'm waiting for SiyahKernel 3.1 to be released while keeping wifi off.
On the changelog for RC6, it says that the "battery drain issue" is fixed, and on the changelog for 3.1, it says "new wifi drivers", so I'm assuming it'll be ok once the 3.1 is released. Thanks for all your replies and help.

OK! I've read your situation. This is the only thing that I can recommend. Try installing a Gingerbread rom and see if the issue persists. If it does then some of your application could be the culprit behind the battery draining issue. But again, thats just a guess...And if it is one of your applications that is causing the drain then you should install bettebatterystats from this thread:
http://forum.xda-developers.com/showthread.php?t=1179809
Then charge your battery to 100% and try a new calibration method, maybe you haven't heard of it. But if you charge till 100% then take out the battery for exactly 3 minutes and put it back in and power up your phone and use your phone normally as you do and then at 20% or lower go and check betterbatterystats and see what is causing the most of the battery drain.
Have a great day and good luck with the battery drain, hope this helps!!
Did you check the ROM FAQ about battery draining?
Please check it out. There is also an example of making some changes using extweaks which comes installed by default with ICS Resurrection 1.9.1.

i did read about the new method today, but havent had the chance to try it yet.
im not sure if it's a certain application that causes it, but in the battery stats it points out "Android OS", i've seen many galaxy nexus users complain about the same problem, even with stock kernel/roms, and galaxy S2 users that moved from gingerbread to ICS. it's logical that ICS will take more battery because of the control over multiple cpus and all this kind of stuff but im not sure how much it is about that "Android OS".
anyway ill try to have this battery calibration new method once my battery will drain out, and im probably not going to go down to gingerbread again because i already know its not gonna persist because i remmember how my phone behaved on GB and that those 2 systems work completely different and i want to solve the drain per ICS and not solve the issue by downgrading back down to gingerbread.
thank you for your time and help anyway
