I'm not sure if other X2's do this, but my battery runs fine. I get a solid 10 hours of hard use out of it.
But lately I noticed that if I simply reboot I get another 20%-50% out of it. Yesterday, it was down to around 30%, restarted, went back up to 80% and drained normally the rest of the night.
Is this normal? Is there a fix or something I can do? I wish I could just get the most out of the battery without having to restart.
I'm just running rooted 2.3.4. I do the whole drain it to 0% once a month thing & fully charge.

P.S. I'm not making this up. Lol.
2.3.4 is the problem. There is a battery bug in the software where it reports less battery power than you have. Then, when you reboot, it might shoot up 5% to 10%.
Many custom ROMs have a fix in it. Not sure what the fix is or if you can apply it to the stock ROM.
Eclipse 2.0.x has the fix, but it also requires updating to the unofficial 2.3.5 OTA upgrade.
CM7 is based on 2.3.4 kernel and seems to have the issue resolved as well.
I see. Well, thank you for your help. Sorry if this is a repeated topic.
I just got started in the whole root/flashing "scene" so I'll have to see what I can do about CM7 now.
For those that want to stay on the stock rom, the fix is here.
Thanks, I'll try this out later.
I could use it too but the download link is dead. Thanks
Tried using new file from updated link but it would not work. Hung up at installing. Had to pull battery to restart phone. Any ideas?? Thanks
Probably something wrong with Peppermint's script. I have the original one from my phone. You can give it a try if you want.

Thanks. It installed OK this time. I'll be checking to see if it makes a difference. Thanks again for the help.
You're welcome. Hope it works for you.

I bought my mother an x2, rooted and flashed CM7, she gets around 15 hours on the stock battery.
You will notice a huge change in performance, battery and more while you flash any ROM... Good luck, just follow the tutorials here in the forum.

Hey can anyone help with my battery prob? I got the extended battery from verizon I wiped battery stats after draining it fully and recharging fully twice. I'm running eclipse 1.3, speedy v7, and the cdma unthrottle mods. For some reason my phone eats this battery faster than my stock battery.

Hi guys,
Since the update via ota to xxlpq (polish unbranded phone) my battery life has gotten real bad.
After 1h out of charge in the morning, I'm down to 70%
While on 2.3 I could get two solid days out of the phone.
Any idea why that may, be and what I can do?

Install BetterBatteryStats, let the phone run for 8-10 hrs.
Then go to the BetterBatteryStats thread on here, read the first page & the last 10 pages which will give you an idea of what info you'll need to post in order for the guys who regularly post to thread to maybe help you out/identify wakelocks which might be causing your CPU to get hammered/battery to drain rapidly.
There are many customized rom you developers section...you should try to change... i've tested many ics roms and usually have a very good battery life!!
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!

Hi, I downloaded and installed XWLPY NeatRom Lite v3.5 (18th October 2012)a couple of days ago and now my battery is draining extremely fast. I tried a couple of battery managers and nothing seems to work.
Anyone with any ideas on what I can do to remedy this? Plus I can't see the update section in my settings, is it removed with this software?

The ROM doesnt have an update because the devs have removed it because you just flash an update. As for the battery drain give it a few more days if the problem persists try another ROM. If it still persists after that try recalibrating the battery or resetting the fuel gauge chip.
Hope this helps

Hi,
NeatROM 3.5 is one of the best ROMs from battery backup perspective. And I can say that because I am using it since 3.5 came out and have never had any issues.
For a better battery life, follow the steps from the link,
http://forum.xda-developers.com/showpost.php?p=33045733&postcount=8776
Please note that the instructions are prepared to get the most out of your battery. Even if you follow the few ones that you are comfortable with, you will surely see some improvement.
Please press Thanks if this has helped you.

Its simple mate. Just download an app and hit a button.
Usually battery drain is due to one of two things.
-Phone not going into deep sleep
-Wakelocks.
Download an app like CPU spy. you can use it to see whether or not your phone is going into deep sleep like it should. Also, use better battery stats to look for wakelocks. Download the app from HERE , let it run for one battery cycle and then check for wakelocks. If you dont know what those are, spend some time reading that thread.
But if you want to hold off for a couple of days, you can do that. It does take some time for a phone battery to settle when a new rom/kernel has been installed, after which battery life tends to improve.

Thank you very much for your help mate. I've tried a couple of battery managers off play (juice defender and another one). Right now kind of regretting this download, everything seems to be going wrong;
1. battery is draining @ 15% in 20 mins ( I only bought the battery last week after having the phone unlocked).
2. there's a lot of lag
3. screens keep freezing and
4. keep losing reception and constantly having to restart phone.
I only downloaded this cause after unlocking my phone it failed to update. Is there any other that I can download that works well with SGS2?
There's no dearth of ROMs for the i9100 dude. Try a couple out and see if those help. If its stability you're after, maybe use an ICS Rom rather than JB.
15% in 20 mins isn't normal even for a first day..you sure it isn't a faulty battery right? Was it giving decent life before you switched to this ROM?
Try downloading a calibration app and see what the voltage is when it says its charged 100%. Should be around 4100-4200 mAh.
As for the lags and freezes, did you wipe data, cache etc before you installed this Rom?

I had cleared the cache in settings before installing. Like I said, my first time doing this. Seemed straight forward at the time.
Since my phone is unlocked, will it return to ics4.0.3 which is what I had before?
Battery calibration app is showing 4161mv.
Will a factory reset help?
Thanks for all the help, site can be a bit confusing sometimes lol.

Cache from settings? No. I meant clearing cache from the CWM recovery menu. If you installed the ROM via CWM, that is.
If you did, I'd suggest reinstalling it again via cwm this time clearing data, cache and dalvik cache.
Ok..I just realised I totally assumed you'd installed it using CWM. Not sure if you did.
You can return to 4.0.3 if you want. Download stock firmware from sammobile.com and install it via Odin. I'm sure there's a guide on how to do that somewhere on this site.
Just noticed someone posted instructions on maximising battery. Did you use those? It could explain the freezes if they started after that. Some phones just can't handle undervolting etc.

Morning, I downloaded some battery managers and seems to be working better and faster. Battery discharged 27% in 5 hours.
Will see how it goes over the next couple of days.
Teaches me a lesson to do my research first lol.
Below is a screen shot of the apps I installed.
Thanks and gave a great day!
Sent from my GT-I9100 using xda app-developers app
Haha that's a lotta apps just to save battery. As long as it helps eh? 27% in 5 hours is pretty acceptable for moderately heavy use. Depends on your signal strength and whether you're using data or on WiFi etc.

Hi all, I was trying to post this question directly in the forums but looks like i have not permissions to post on the developers threads since this is my first post :crying:
I have a question about battery duration with the omega rom on my SGS II.
First i flashed version 16.2 and i saw my phone's battery life was not very good (10-12 hrs average). i thought it could be all the things this JB rom can do (like smart stay and all that kind of stuff) so i went back to the Omega ICS v15.1 but same thing with the battery life, i wa doing at least two recharges per day. Then i saw that the omega v17 was released so i decided to give it a try hoping thing will be better.
I alredy did the rescvan media root app thing, disabling sync, and all those tips with no difference.
Am I missing something, does my battery needs to be replaced? (i bouthg the phone like a year ago).
And what is the average normal duration with this ROM?
Thanks in advance!!
(I'm attaching an SS of my battery stats)

Hi I'm in a similar position on a jb ROM also get not many hours 10-15 as u can see nearing 6hrs will probably get some where between 50-60% battery it just feels like it drains fast when I use it and when its on sleep as well. I'm also doing all the tweaks to save battery life changing govenor turning off sync killing apps low brightness etc. Still feels like short battery when phone being used or in sleep. Tried several jb roms. On siyah betav4
