If you have Battery Problems Please read! - AT&T Samsung Galaxy S II SGH-I777

A couple of months ago I installed the AOKP ICS rom Then JB and found it about as good as you could want, but this is not about how good the rom is. I have been flashing a couple of years and know enough to get by. As much as I loved the rom i was almost ready to flash back to stock because I was unable to get any battery life. I would always use at least 8% at night and up to 15% during the day. I just couldn't understand how so many people were saying they were getting great battery life. I went through all the posts and tried every option i could find, watching wakelocks every time I picked up the phone, changing my router settings, turning off everything on the phone that made it a great phone. When I originally installed ICS I did a total factory reset, cleared all cashes. Spent hours reading everything I could find about battery life problems. When i flashed JB it was the same thing. I have been flashing the updates every week. Clearing everything every time.
Last night i was about done and figured I would try this one more time. I downloaded the rom and Gapps again, but this time i did a factory reset 3 times and cleared the cashes 3 times. Then when the system was installed I downloaded clean apps from the the Play store. I installed everything normal, all sync settings on, the phone is set up just like you would want it with full functional apps. This morning I woke up and checked the battery and it was down 2% for 5hrs! That is the best I have ever seen and I think about all you could ask for. The history had no wake locks, No awake times when the phone was sleeping. Now at 10 hrs and and 5 hrs of lite use I am at 82% and still no wake locks or anything unexpected by any apps like I always had before. Google Now is running, sync is on, like I said the phone is set up normal not everything shut off.
I am not saying that you need to clear everything 3 , 4 or 10 times when you flash a rom or not use TI to restore your Apps. What I am saying is, if after flashing a rom you are not getting good battery life or you are having any strange lock ups with your phone THEN start from scratch and make sure every app on your phone is perfect. BTW my phone was getting terrible battery life but working as smooth as butter all the time. I didint have to wait 3 battery cycles to get get 10 hrs out of my phone, it worked as I said from the start. If you phone isn't doing as good as other people are and your not expecting to get 2 days with 10 hrs of screen time, Clean out everything and start over, esp on a Rom like AOKP, these phones should work GREAT and it only takes one bad app to kill things.
So listen to the developers and clean house if things aren't right !!!!!!! It takes more time at first but over the last 2 months I have spent about 10 times more trying to fix the phone.

Do some of you other users get 8+ hours of screen on time? I got my i777 around launch time and I don't think I have seen over 4hrs of screen on time. I have tried a lot of different ROMs, like aokp, shoshock2, and currently cm10, and my general consensus is 3+ hours is good.

Never seen 8 hours with stock battery. Max I have gotten is 5 and a half. I could probably get more on Shostock but I was on AOKP JB

I'm going to have to do this tonight. I'm really not looking forward to it though because I've been trying to unlock things in Fruit Ninja but I want to get this thing working right so that's how it goes.

Just back up data

im going to try this, i was using the wipe 3 or 4 times method when i had a sony x10 phone a year ago and it seemed to make a difference.
aokp is a really great rom and on the previous version my phone could last a full 24 hours (about 9 of those hours probbaly not really any use)
latest version the battery is a bit trippy for me so im going to try this and i wont be surprised if this is all true.
thanks!

Just an update. 16 hrs, 1 hr screen 69% battery left.
To SteveO I would not restore any apps you have with a backup. If you do the complete wipe it seems that the Play store actually downloaded all the Apps fresh on its own. I think that may have something to do with really getting a clean plate. I have wiped many times and only one other time did the Play store auto load my apps.

I also recommend wiping internal and external storage everynow and then. Backup pics, music and the such

I had a feeling that's what you meant, to NOT restore a back up.
As for the "auto load" from the Play store, are you referring to when it asks you on start up if I want to restore my apps from Google Play you're suggesting I say yes, correct? Is that what you did?
I was planning on making a list of what's on my phone now and manually downloading each one and installing.

So what's the point here?
In order to get great (or better in this case) battery life of AOKP, do
1. wipe 3 times
2. install and run one of the clean app from Google Play. Which app, actually?
For some reason, I "feel" that after performing TB backups (user data backups), the battery life gets worse.

There really isnt any "point". I was just letting others know what i did to GREATLY increase my battery life. I dont think it has anything to dowith this ROM. I think if you flash any Rom and your not happy with the Battery life it may be a bad apk that doesnt get cleaned out with the normal route.
I advise installing ALL your apps clean, not any one.
I mentioned that the PLAY store automatically offered to reinstall all my apps after this clean wipe. Other times i have flashed it didnt do this so it makes me think that for some reason something doesnt really get cleared as we think it should, again no expert, only telling what i found after about 20 Rom flashes over the last couple of years.

I just had a really good test of this procedure. My usb port crapped out so I returned my phone for a warranty replacement.
My old handset has been laggy since upgrading to Jelly Bean. I'd always restore apps through Tibu, only restored data on a few apps.
Fresh clean I777 stock Sammy, runs smooth on ICS.
Newly rooted, AOKP 11/9, basic GAPPS and the same Tibu restore => laggy.
So I factory reset, wiped everything including internal storage, let Play restore my apps, input all the app data manually, and this phone is smooth.

[Q] Which ROM is best for battery?

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??

Stock rom/
jje
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)
Insanity
Go for the insanity ROM, only problem is, whatever ROM you choose, you will have to calibrate your battery.

Is this battery performance normal on ICS LPQ?

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.
Thanks.
Ooh my holy f#, the amount of ics battery threads its too damn high

Official OTA ICS Upgrade is a Complete Disaster

I apologize if this thread is a tad redundant, but I believe it goes beyond your run-of-the-mill glitches that one might post about in the ICS Bugs thread.
I got my OTA upgrade about 10 days ago, and since then my RAZR has been utterly useless.
The biggest problem is an obvious issue with power management. With GB I used to get almost a full day of heavy use. Now I get 2 hours, 3 if I'm lucky. I often find that the phone is extremely hot, as if the processor and radios are running at 100% for no reason.
Perhaps worse than that, it takes infinitely longer to charge than it used to. As in, 5+ hours to go from 0% to 100% -- and that's while the phone is powered off. Powered on, it'll take even longer.
I've experienced issues with almost every app, and with some I've had literally no success whatsoever. Facebook freezes half of the time before even loading up. The stock Browser will freeze a few times a day. Alarm Clock Xtreme freezes whenever I try to edit an alarm. Neither the stock Gallery nor third-party image apps will load up any of my photos without freezing. Google Talk won't initiate video chats. The list goes on and on.
Moreover, the phone will often just freeze outright. Sometimes the screen won't light up, regardless of how many times I press the power button. Sometimes the phone gets stuck on the home screen, and responds to nothing. Sometimes the phone becomes unresponsive, although pressing the capacitive buttons still triggers haptic feedback. Because of this, several times a day I just hold power+down to shut it off the hard way.
At this point, I actually avoid using it. It's that useless. It's more burdensome than it is helpful. It sucks because, when it's working, everything is really smooth and the ICS interface is really cool. I can tell it would be awesome, if only it worked.
Has anyone experienced such madness as this?
FYI, I'm running:
Android version 4.0.4
System version 6.16.211.XT912.Verizon.en.US
Baseband version CDMA_N_05.11.01PLTEDC_U_09.11.00
Kernel version 3.0.8-g29cf5e7, [email protected] #1
Build number 6.7.2-180_DHD-16_M4-31
I can't believe they would release something so unstable.
And yes I've gone into recovery and wiped the cache partition several times to no avail.
I admit there are some issues with the battery and heat and bugs, but i have not experienced any freezing with the stock browser or any program really, alarm clock extreme and it works for me, I don't use the Facebook app often but the few times i have, no real issues sometimes it lags trying to update. I will say thay the market SUCKS or play whatever they call it. Maybe you got a corrupt OTA file or something is wrong with your update installation. Maybe try doing a factory reset, i know that sucks to do but i do it before every OTA and im not really experiencing any of the software issues you are experiencing. If that doesn't help, root it and use the razr 1.7 utility to reinstall the system files.
Did you try to wipe the device (factory default)? It helped in my case.

If you wana solution to some problems without wiping the phone, boot into recovery and wipe the cache, fixed my battery and a few other problems, It doesnt remove anything you have done, also it eliminated my lagg problem.

ICS is very different from GB, and Motonverizola tried really hard to get ICS to play well with existing GB cache data and GB settings. All of that stuff changed a LOT.
The problem isn't ICS: the problem is data conversion from GB to ICS.
Wipe the cache and dalvik. If that doesn't get it, then do a factory reset and set everything up again.
Mine runs for days with light use (1-3 hours a day), or a day+ with heavy use. It doesn't get hot, unless you mean that the other way. But that'd be kinda creepy.
Hi
This is my first post here at this forum and I'm not a Razr user but thinking about getting the Maxx because of it's hardware and big battery which fits my usage of a smartphone, I have a Galaxy S right now.
I have looked at some of the posts and screenshots of the battery usage on the new leaked/released ICS for the Razr and read about complains about the short lived battery and the devices that overheat, well, we had the same problem when GB has been released to the Galaxy S and that is all related to the Android OS app that is using the battery because it's got into a loop, this will not get fixed unless you make Motorola aware of the problem. I could be wrong but I think that is related to the dalvik-machine. Android OS should be using around a single-digit of the battery of all time (3%-7%), we don't have this issue anymore since Samsung fixed this bug in the later releases of GB firmwares.
A temporary fix of the Android OS is to reboot the phone when you can see that it's hijacking the battery, this is until Motorola fixes the issue.
I wish you all good luck and hope that you will get a better firmware soon.
Its always good practice to start fresh when accepting an update that big. Less variables = less problems.....
Id do a factory reset and start from scratch... that sux... i know, but so does a useless phone
Ics def wasnt all the hype.... but its also not that bad... just gotta start clean.
Good luck!
Complete disaster? How is it a disaster compared to my update? After the update I could no longer receive text messages, Consider the fact that I send a receive hundreds of text messages per day this is honestly the biggest cause of outrage I have with a flagship that can't perform even what a Nokia 6280 could, when I finally receive texts they come in 4 hours late and worse still, in DUPLICATES and I can't seem to find any solution to this as of yet. A factory reset fixes this for an hour at best but the problem suffices after that. Does anyone have a SOLUTION to this? Honestly driving me nuts
I agree with most others... do a factory reset. I always do after a major upgrade (and ICS is a major upgrade!)
Then check what apps you are putting on the machine; some cause issues. For instance, I put the new Starbucks 2.0 app upgrade on my phone yesterday - consumed battery like mad, phone ran hot (like cook-an-egg-on-it hot), runaway processes, etc. Turns out it was the new Starbucks app; after removing it the phone ran normal.
Otherwise I love ICS! So try the cache wipe; and if that doesn't help then do a factory reset and reinstall things. Takes time, but it saves in the long run.
Wow, this is crazy to hear. My update has been flawless but I did a factory reset after getting it. I bet if you did that it would fix 99% of your problems.
I also rooted after and now I'm running a cm9 rom. This is the best my phone has ever run.
Ultimately, even if you don't root you can fix most of these problems with a factory reset.

Hold down the Home button to see what's running, download a task manager to see what's dominating the CPU. The phone won't get hot by itself, something is using up the CPU (like you said) if you don't want to factory reset you've got to figure out what it is. Rooting and setting the CPU governor to hotplug will save quite a bit in battery (shuts the 2nd core off when not needed).
I'm on a Canadian leak, the first day battery performance was terrible. By the 4th day, the battery lasted longer than GB
I concur with everyone here about the factory reset.
As other's have mentioned, going from GB to ICS is a major overhaul. I've read elsewhere what this really entails and it's not pretty. Suffice it to say, I backed up all my user apps and data (using Titanium Backup), saved off all other things that were on my internal SD card just to be safe and then applied the OTA update in stock recovery, wiped data and cache and rebooted. I then rooted, installed Safestrap and flashed Eclipse ICS v1.2 RC1 and restored my apps with TiBu.
I also tried stock ROM as well and restored my apps via TiBu.
In both cases, no performance issues nor forced closes. Runs like a champ.
I'm running the latest .214 leak and my battery life has improved over .211.
.214
Razr Maxx
I was having shorter battery life with the ICS .211 build and then updated to .214
My battery life is way better then it ever was with GB or ICS .211
I ran it the other day for 36hrs and 3 of it actually talking on the phone and had 20% battery life left.
It has currently been on for 4hrs 6 min and is at 90%. light email and phone use. I do have an IMAP email account that poles every 10 minutes with push for instant updates.
Mine is running fine after simple reboot
I am getting great battery life and my Razr Maxx is working almost flawlessly after the ICS OTA stock update. I just rebooted it shortly after the update when it was running hot and haven't had any problems since.
If .214 is even better, great.
Looking forward to Jelly Bean to get even more from my device.

Was on the soak test and had the same battery problems. Only way to fix was via a factory reset. This did however fix all the problems.

Thanks for the replies everyone.
As mentioned I have tried booting into recovery and clearing the cache, but it doesn't help.
Some have suggested wiping the dalvik cache. However I don't see that as an option in the recovery menu. Do I need to root to have that option? Excuse my newness to this.
Worst case I guess I'll just have to do a factory reset

[Q] Terrible battery life

Somehow, it seems over time battery life on ICS has consistently diminished. May try some things but this is stock rom, and really not a lot of apps widgets. Is everyone having this?
Example, Sunday I unplug it at noon, and by 7 its at 4%, made a few calls, say 3 under 5 min. Used navigation some, texted some, and a bit of fantasy football app. But that seems below reasonable expectations.
Widgets: 1 weather, Tim Hutt ICS calendar, SiMi Clock, battery & Weather(lockscreen), Widget Locker, Google Music. Launcher: Apex pro.
Did a bit of surfing and didn't see much around stock ICS (could have missed it)

I'm on the US AT&T stock ICS. Have not tried any roms.
If you upgraded via kies or OTA...the chance of a corrupted flash is high.
I'm not saying that it is, but we have had several reports of failed OTA or kies upgrades to ICS...
The only good fix is a re-install of the build...
I would go to samfirmware.com, and push the rom to the device again, and then test the battery life.
this would not be the first bad rom image we have seen from the upgrade.....g
And remember, it takes 3-5 days of normal usage after a fresh install, for the dalvik cache to build, and for the device to "settle" before any accuracy can be measured...g

If this is the case, should I try something like a factory reset then reinstall? I initially updated via Keis.
What is typical battery life on ICS? I recall I got the note right before going to SXSW and it would run from 8am to 11pm with solid use and maybe a 10-20% top off somewhere in the day. This has given me serious cell phone "range anxiety", even bought a external battery to address it.

Best screen on times I've seen are ranging from 3-4 hours, and overall battery times are going 18-24 hours...
Now mileage varies greatly between users, and i'm running ICS as well, and since 6 a.m. today, I've used 14% battery in 7 hours...
I've made 2 phone calls, sent 3 texts, and messed around with settings for about 30 minutes...
It does sound like you may have gotten a dirty flash image...but it's so hard to tell, unless you get random freezes, boot loops etc.
But the stock ICS battery life was horrible for me........g

Now mileage varies greatly between users, and i'm running ICS as well, and since 6 a.m. today, I've used 14% battery in 7 hours...
I've made 2 phone calls, sent 3 texts, and messed around with settings for about 30 minutes...
It does sound like you may have gotten a dirty flash image...but it's so hard to tell, unless you get random freezes, boot loops etc.
But the stock ICS battery life was horrible for me........g

It boots and actually runs fine. Occasionally cell standby chews the battery out of nowhere, andriod os and phone idle too.
I pulled it off the charger today at 9am and as of 2:00 I was at 68%. Checked email, messed on flipboard while making coffee, updated a few apps. Checked traffic. Mostly just sat on my desk.

Yeh...thats nearly double the battery drain i'm seeing.....
I really think you should either re-flash the stock build using samfirmware.com, or flash up a custom rom you can adjust to get this battery issue under control...g

Agh, yeah I'll have to give that a shot... Been looking at CM10 or something, I had a jailbroken iPhone4 previously so I'm not ADVERSE to doing this... was hoping to stay stock a little bit longer... I know the samfirmware thing is the stock firmware but still, playing with the OS DOES cause a bit of anxiety...

Though, would a factory reset take it back to GB and allow me to do the upgrade again?

But you can push the factory roms to the device any time you wish ....it's endless really ....g

Understood ...
Fortunately, the note is painless to use on custom roms ...
With the ATT version, you simply push a custom recovery to the device via Odin, then download and flash the rom.
No root needed. And if you don't like it, you restore the stock nandroid backup and presto...no more rom.
Root is very nice though, as it allows sooo much more control ....g
Extra Batteries, their cheap and totally worth it just make sure you get a wall charger too
I've pretty much given up on eking out more battery life since it seems universally bad.
A bit more than 4 hours screen-on time seems to be the limit without setting the screen to ultra dim.
Standby seems entire dependent on my signal strength and whether I have LTE enabled or not. If it's strong, 24+ hours isn't unreasonable.

Well, yeah screen destroys the battery. After ICS it seems as though they cranked up the brightness and contrast. Or is that just me?

[Q] 1) Upgraded from 2.3.3 to 4.1.2 by Samsung. 2) Battery hates me. 3) :( :( :(

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.

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.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
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.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.
You searched Ebay for "Samsung genuine 2000 mAh battery" or similar?

Cyanogenmod roms are very fast ROM they are good as hell
Ur problem is genuine go to the playstore and download battery calibration app and follow the instructions in the app charge or battery up to 100 % and caliberate the battery u should have made an nandroid backup before upgrading

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.

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