Okay I need a ROM with battery for tonight only! Going on a night out, getting wrecked and all that, and the last time I did it, my phone died and I really needed it later in the night to contact my mates when I was a mess. I don't want it to happen again tonight, even if I turn data off and everything.
So what can people recommend? Is Oxygen a good shout??

You do some really heavy usage there if you can discharge it that fast. Mine lasts 24 hours easily with medium usage. I've only tried stock, villain and CM7, and from my experience CM7 saved the most battery (in idle mode at least).
Well, I can't comment on my usage as I was disgustingly drunk that time. But I really don't think I had data on, and the only thing I was doing was texting. A few calls here and there.
But I have a stock nandroid I may go back to, or I might just go for it with my MIUI. It may have been the version I was on?
Stock...i feel...tried villain2.4.2 also, but back to stock now.

The actual ROM wouldn't play a massive part in battery life although of course it needs to be included, what you need to do first and foremost (assuming your rooted) is get Titanium Backup (PRO version) and freeze all Samsung bloatware, there is a spreadsheet on page 13 http://forum.xda-developers.com/showthread.php?t=1069924 freeze everything you don't need, personally i froze just about everything i could including Maps, anything you need to use occasionally just defrost it, use it and freeze it again, don't use any battery saving apps like Juice Defender or the likes as they use up as much battery as they save, install better battery stats and check what wakelocks are keeping your phone from sleeping, obviously things like bluetooth,GPS and the likes will drain your battery so keep them off while not using, sign out of any apps if your not using them,i can also recommend Cognition ROM ive been using it now for ages and it's always good on the battery, and last but not least search the forum there have been hundreds of battery posts on here over the last few months.
After all that you might get battery life like i do (see screenshots)

Go for the insanity ROM, only problem is, whatever ROM you choose, you will have to calibrate your battery.

Dear Users
I have the XEWK7 SGS2 Rooted Stock Rom, Ive removed most of the nonsense software, and got the basics only. I have also removed TW Launcher and set up Go Launcher. Simply because it is a lot faster and better. Ive done something to slow it down, and decrease battery life, and thus before I restore it to the SGS2 rm, I decided to try other roms, like the lightening rom, can anyone suggest if this will be conducive or adverse to my settings now?
Thanks.
Flashing a new ROM will be the same as factory resetting it (but obviously with a different ROM), so your current setup will be gone and is therefore irrelevant, or am I not understanding your question?
I am reading it the same .Files gone .
Or is the question >> Are other roms better than your own settings >> Answer is who knows .
Backup current rom and you can always flash it back .
jje
Incidentally, I can't comment on any of the ROMs cos I'm still on stock - all I've done is rooted it. But I can say for sure that I wouldn't bother trying to make this thing faster as it's ridiculously fast already!
If you did something to slow it down then maybe try freezing apps 1-by-1 until you find out what the problem is.
thye main problem is battery drain. Ive removed bloatware, no gps, no 3g, no wifi, bluetoot, brightness at 10% and running mail sync with news and weather. my battery isfinished in 9 hrs without much calling. I need the dam thing to last atleast 15-18 hrs. Im also using 1800mah batteries.

Ok, now my phone is giving me good battery life. 6 hrs of moderate usage, only 25% gone....what is the longest anyone got out of a battery with constand Email sync?
Hi guys i really need someones help to explain something to me. I not even had a galaxy s2 for a month and i have been noticing problems with it. I flashed different custom roms because i heard having a custom rom is more battery friendly and makes the phone go a lot faster than having the stock rom in. So i went ahead and flashed a custom rom but i have been having problems with the battery. Fully charge it and within minutes of using wifi and browsing in the browser the battery starts being drained like crazy. Anyways i called the place were i got it from and i have send it in to them for an exchange. They said to me they will have to test it first to see were the fault is before they do the exchange. I have to say here that i flashed back to stock rom with the latest firmware using Kies. Anyways they had it for a few days fully charged it and they say that they can not find a fault and they are sending me the handset back. I have to admit being on stock rom the battery does last longer.
Anyways what can i do next and were is it that im going wrong and is it worth sending it to Samsung directly once i get my handset back?
Does it take few days for the battery to settle and get the proper use out of it even with a custom rom or shall i just stick with the stock and just root and use my phone as normal because other than the drainage there is nothing else wrong with it.
Thank you in advance...

hey thanks again JJEGAN for replying but why does everyone suggest to go to custom rom then? and i have display on lowest and i hardly have widgets so why on custom rom my battery gets sucked like crazy? do you think its worth staying on stock rom and just root the handset?
Thanks
ps when you say wipe the battery stats i did do that and charged the battery and still the same so were do i go wrong? could it be the custom roms that i have been using and not let the battery have a few days cycle to adjust to the new rom
Why do you want to root it? The phone is a beast on stock. Save yourself a load of hassle and get timely OS updates by staying stock. Root in a years time when the phone gets old and isn't supported anymore.

Read the battery drain posts stop your apps from draining the battery .
Overnight sleep test with GPS Bluetooth and WiFi off on a fully charged battery target 2% drain per twelve hours . Better Battery stats set to show Wakelocks .

Hey I installed MIUI-NB a few days ago when it was released and am wondering how the battery is or if its supposed to even out? Mine lasts about 5 hours on light use and just an hour ago I had it at 87% and its now at 15% and all I did was mess with the theme a bit. I even have the data off. Is that normal for MIUI?
tough call, i flashed back to stock, had serious problems, i liked the build but too many scripts ,my phone couldnt hang, great idea just too muchfooofooo
you think the scripts have to do with the battery drain? I heard extended settings also causes battery drain.
1) Have you done atleast 3 battery calibrations?
2) If you have, does the battery stay bad even on froyo stock roms?
3) if they do, then your battery is most likely faulty.
Yup done the calibration and I can get through the whole day on a 2.2 rom so its not the battery.
I'm using MIUI-NB with Glitch v12. With JuiceDefender running, I can get more than 48hrs on light use (texting, car music, light gaming), and going 24hrs with heavy use is no problem.
Like the creator said, let it settle.
yeah for sure, what were you getting the first 2 days?
Problem with Titanium backup
Hi,
I just flashed the MIUI-NB rom. Looks really great.... but I previously had a different rom and had taken a backup of my contacts with Titanium backup. But now when I try to restore the contacts with titanium backup I see that its successful but there are no contacts. And when I choose to restore App+Data it gives me an error stating the contacts app cannot be installed.
Please can anyone help me out here.
Thanks a lot guys.
GPS
I flushed this rom several times...could not get GPS working.
I've followed the instructions: flush, wait, reboot, wait, foxGPS, reboot, angryGPS lock test.
so when I do angryGPS lock test, it looks like crazzzy but after that GPS would stop working at all!!! no mater what I do! I have replaced lib files for FFC so maby that what cosing it.
By the way what is the best stable GB rom for the vibrant for daily use?
I've been using boinx V and 1.3.1, but now I'me tiring to move to 2.3. I've also installed FFC just a week ago.
Please help!

Hi, I just recently flashed the LPG ICS Rom to my phone 2 days ago. I did the wipe and flashed through mobile Odin. I restored some of my apps and data with Titanium (also uninstalled most of the samsung apps)
I already did a battery recalibration (pulling the battery at 100% etc.) but I am getting pretty bad numbers. Just 7 hours tops, I guess a lot more if I dont turn on the phone but I guess this is really wrong.
Am I missing something? Should I uninstall or disable something more? This exact configuration gave me minimun 12 to 14 hours on a stock not ICS ROM.
Also I should mention that I am using Juice Defender Ultimate with connection intervals of 5 minutes, pretty average settings.
Any suggestions, tips or guesses?
Thanks a lot!
PS. I dont have any strange apps, just the normal (facebook, twitter, whatsapp, Talk...), My display brightness is set to auto.
What really matters is screen on time and you are getting barely 2 hrs and that is indeed awful but in line with all the complaints I've been seeing in the forums.
The update I got was not LPQ but rather LPE (Trinidad & Tobago) which was released the same day as LPQ. I am getting 4.5 hrs screen on time (around 15 hours with my usage habits). This is barely acceptable as I usually got 5 hours 15 min of screen on time with my stock 2.3.4.
Hopefully Samsung will fix this soon, it was supposed to be the other way (battery life improvement).
Soo...
So I guess I'll just have to wait the next rom releases, as it seems that they are improving the rom every new release? Does that make sense? the roms are being released almost one day apart from each other, arent they the same?
In case that for example a new rom comes out tomorrow and the fellows here say that it really improves battery life. What should I do? wipe and install just as this one? or would I be fine without wiping?
Thanks a lot!

Their is no normal battery usage and you have not given battery any time at all to recalibrate .
Just read the battery posts and use Better Battery Stats .
If their is a problem a full wipe is always best .

Ok, so after a couple of days using it.
The battery now lasts almost 9 to 10 hours with normal use. but I deactivated Juice defender.
Now I have disabled all of google location stuff, and some of google services autosync (like google photos and reader). And will turn on juice defender to see how it goes.
Ill update my findings.

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

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.

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).

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.
