Hi. There are a lot of battery threads - a lot!, but after using search I found nothing relating to this problem.
My phone was fine up until a week ago or so. I'm on stock 2.3.5 after upgrading from VillainRom (which was great, but I just wanted stock back).
I've been back on stock since 2.3.5 released and everything was great. I froze/stopped the bloatware ect..
But the last week or so my battery drains 45-50% a night. I have wifi off and also the data network is off. I don't know what could be doing this.
Could someone help trouble shoot this please? As I said, it was perfect before, I don't think I've changed anything, wifi and data are off overnight, all apps closed.
Thanks very much.
EDIT - So I bought two new batteries and I still have the same problem. I've even went back to VillainRom 3.0
Now here's the kicker, after putting my phone on charge in the morning, after two minutes it's up to 46%. So whatever is happening it's not the battery draining, it's a software bug or a hardware bug or something.
Has anyone heard of this? And what's the best way to go about this?
Also, why would this only happen overnight and not during the day?
EDIT 2
I have attached 3 screenshots of my battery stats.

Better Battery Stats should be of help.
You'll be interested in Partial Wakelocks, and possibly Kernel Wakelocks. If you're unsure of anything post in that thread and someone should be able to point you to a solution.

Thanks. I've been trying that since you suggested it. It hasn't helped. I'm thinking it's a software problem, so I'm going to start fresh.
Thanks for the suggestion though.
Maybe you can try to do a factory reset and start again from the beginning (gmail account, install apps, etc...)

Yeah, that's what I'm just about to do. I'm also reading about Villain 3.0, might give that a go while I'm at it.
So I bought two new batteries and I still have the same problem. I've even went back to VillainRom 3.0
Now here's the kicker, after putting my phone on charge in the morning, after two minutes it's up to 46%. So whatever is happening it's not the battery draining, it's a software bug or a hardware bug or something.

Try recalibrating your battery. Drain it completely to 0 and charge fully. Then wipe the battery. Status.

I did that with my last battery, which is what prompted me to buy new ones. I also wiped the battery stats again when I installed villainrom.

DON'T DO THIS.
There batteries are not meant to drain to 0%. It could damage your batterie.
If you already wiped your batterie stats with this batterie, just use your phone and charge it when it's almost empty. Repeat this a few times. It is possible that your batterie needs to settle in and that your problem is solved in a few days.
If not, try flashing an other rom. Make sure you wipe everything (except batterie stats, because you already had).
Yep do not drain it completely.
I would recommed to calbirate your battery. It seems that your battery stats are somehow off.
Use this guide here:
http://forum.xda-developers.com/showthread.php?t=1312273
If it does not helpt do it againg and go through a few charge cycles.
If the problem still persits I would consider a factory reset.
download battery calibration from market and follow instruction.
Thanks for the replys, but none of this has helped. What else could it be?
Imho the Battery will never drains to zero, the phone will turn off before, so let your phone on until it turns off by low voltage, if you afraid ruin your battery, use the eldest, you already got 2 spare batts
I had a similare issue some weeks ago and my phone went dead 3 !! hours after the indicator reaches zero.
Maybe it helps.. (No guarentee)
Just to be sure, have you tried a different charger? perhaps yours is messed up?
BTW, i flashed 4 different ROMS in the last 2 month, and i never wiped my batterystatts .. no issue with that (for me)
Try a different kernel, based on my experience, the rom is almost nonrelevant to battery usage, the kernel makes the major difference, give Phenomenal Extreme a try, this kernel boosts your Battery for real! -> http://forum.xda-developers.com/showthread.php?t=1351191
Turn of location service and facebook
Good Luck! Feedback appreciated..
if you wipe to factory resets, add your google account, but don't add anything else, does the same thing occur?
If so, I would say it's a hardware issue, otherwise it's probably software.
I saw someone suggest using better battery stats, and you said that it didn't help, what do you mean it didn't help? It doesn't fix anything, it just lets you identify WHAT is using the battery.
My Galaxy S used to drain to 50% overnight, turns out it was the instant messaging (using MSN) that was doing it.
Like I said, try it after a clean factory reset with just our gmail account, no MSN, no Hotmail, no Yahoo, etc and no Additional Apps
or you can try speedmod's kernel ... test 13 i think is the latest ..
works a wonder to me in terms of battery performance
I can try another Kernal, but I have switched recently.
Because of this issue, the last time I switched roms and kernals I did a clean start, and I didn't restore anything, I literally started from fresh.
I'm using VillainRom 3.0
Kernal: Siyah 2.1.1
Modem: KI3
I will have another look at battery stats aswell.
I have added some screen caps of my batterys stats to The op, I'd appreciate it if you'd have a look.
Thanks again.
I won't bump this again if there are no replys, but just incase it was missed.
Sorry.
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?
Sent from my GT-I9100 using xda app-developers app
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.

Hello guys,
I'm a little bit desperate with my battery. One month ago I updated from ICS to JB in my s2 i9100 and the horrible loop started:
- Between 100-70% of charge everything is going more or less ok
- Suddenly, phone turns off. After restarting, the battery is around 40% and very unstable
- Now it's even worse, without charger, the phone remains up only 15-20 minutes.
I tried EVERYTHING:
- All the roms for JB (all versions of RR, Paranoid Android) with all the combination of Kernels (CM10, Siyah and Dorimanx)
- Go back to ICS (of course, for every ROM I give to the phone 2-3 days to stabilise it)
- Battery calibration tools of the play store (even I paid 3$ for one of them)
- Battery calibration without being ROOT (the trick of this thread did not work. I tried 3 times)
- Reset fuel gauge chip from the ex-Tweaks
...
Any other idea/clue?
I'm about to give up, I think I'm going to get a new battery. I prefer to pay 15-20$ than spending hours trying to figure it out.
The last question. I'm assuming that a brand new battery will fix this problem. Am I right? I'm afraid of buying a new battery and facing the same issue.
If I get a new one I am supposed to do some operation on the phone before to install it?
Currently I'm using RR 3.1.1 with dorimanx kernel.
Thank you very much in advance!*
You guys do an AWESOME job with this forum.

My battery SUCKS now. If I'm using the telephone in a normal way (surfing, music, videos)... it goes down every 30 minutes.
I'm going to try to remove for a while right now. You mean, minutes, hours, days?
Yes, I tried to wipe battery stats from recovery with no results.
Thank YOU very much for your interest

Try RootBox 3.0 with dorimanx 7.4. I've been using it since it came out with no problems.

Hey,i got RR 3.1.3 since the day its out..had about 5 battery cycles and still having a massive drain
my phone had FULL battery at about 17:00,it got stuck after 30 minutes(in that point i had about 82%),i turned it off by long pressing the power key.
when the phone got up it came with 70% battery,i almost didnt use the phone since then. maybe maximum 30 total minutes on whatsapp.
edit:
here its about 3:23 am now,i got 26% left.
here are the pictures from BBS:

*if you have any recommandation about other ROM(even if its not JellyBean) i dont mind changing so far the battery will be better.
We have already had multiple topics about this.
If you have problems with a specific rom you should check specific roms thread.
So first of all there is a BBS thread where u get better and more direct help to this problem.
Second if u have this since a flash of Rom or kernel try a reflash (maybe a kind of "bad" flash)
If u want a recommendation for another Rom I can say that RootBox is quite good in battery.
U have to choose if 3.2 (4.1.2) or to newest (3.4).

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this
5) Read about jb settings/issues.
Sent from the little guy
Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

As far as the battery issue is concerned,do a clean ROM install through Odin.
