Hello.
I am about to buy the SGS2 and have a couple of questions before I go ahead with my purchase. Currently I have a HTC Desire, and need to know how much I need to change. Here we go:
1) Battery life: I know that it very much varies depending on the usage, but given on average how many hours/days do you actually get out of that battery. With Desire, I am getting 1.5days on medium/low usage.
2) USB: I have a few usb's that were bought for my Desire, and was wondering if I could use them with SGS2? I am specially concerned about the mini-usb ending and its shape. Could anyone confirm whether it looks similar to this or not:
http://www.universalgadgets.co.uk/images/products/Big11_e947682u6x5it.jpg
3) In terms of recoveries and etc, does such thing exist with SGS1/2? Can I use the ClockWorkMod recovery with this?
4) Is the panel full-true multi-touch? Not emulated, since I 'heard' that SGS1 was emulated, and you could only use two fingers in specific motion. This was not the case with HTC Desire, and definitely not the case with iPhone. (please don't bite me for using the 'i' word here ;P )
5) Also, any issues that you (personally) have had with SGS1/2?
I appreciate your help, since I am going to pay £500, thought I should ask my questions first.
Thank you,
Mo.
nothing against u but how can u compare skoda with latest mercedes? are u mad? if u have enough money to buy sgs2 why would u use outdated acesories?
and your questions can be answered...look futher this web site... HTC battery life sux btw...and its well known information...

Thanks! I had already done a google search, XDA search and youtube search, nothing that could be found (which was proven useful for me).
Don't get me wrong, I am not comparing HTC Desire with SGS2. That would be stupid. Hence why I am buying SGS2.
About accessories: The question is, why would I need to buy more accessories - If I can use the one that I already have?! Also, since when, USB2's can get outdated??!
Battery life: On HTC website, it says that it has up to 340hrs of standby time. That's a lie. Also, the battery is only 100mA less than SGS2 battery (yes I know dual core and etc etc). So, again, how many days you are 'actually' getting from this?
Thank you,
Mo.
But the question that remains is, how much battery do you actually get?

1) My battery life has been able to last me through a full day of use. It doesn't have amazing battery life but, it doesnt have terrible battery life. I usually go through around 15-18 hours of use on it. Texts, some games, internet browsing, and a lot of music use and I still haven't had the battery die on me before the day is over.
2) That USB cord should work fine with the SGS II
3) As of right now, there isn't a CWM recovery for the SGS II but, Samsung uses a program called Odin where you can flash different things.
4) As far as I know, the SGS II supports full multi-touch. I remember seeing a video of them testing it can't find the link tho :/
5) The only issue I have with it so far is once its fully charged a notification appears. It might not seem like a problem but, it has woken me up once or twice which is annoying.
Hope this helps.

mate u didnt do a research...if u did u will find out that SGS2 has far better battery performance then any HTC..thats mean heavy ussage - very heavy + gaming etc is around 12-16 hours - medium use is more then 24h and soft usage with 3g on and sync on + phone calls and some wifi is about 1,5-2 days..i hope thats enough ..about battery..
Super Amoled plus - latest technology display - full multi touch ..extremly well responsive - once again..latest technology!...
and if u wanna know more about battery performance there is already topic about it...but i believe u saw it..right?

I have just moved from the HD2 (on Gingerbread) so a close match for your Desire. I was getting battery down to an average of 60% after 24hrs SGS2 is about 70% on the same useage. My car charger works just the same . No clockwork yet, but most devs have only just managed to get their hands on one this week and there is already one rom available. Multi touch works. I loved my HD2 (still do) but this is better.
ok, cool. Thank you guys. Answered my questions
In terms of battery life, I put a lot of effort into tweaking the crap out of my Desire. Using VillianROM and an undervolted+underclocked cpu I tended to sit around 70% after a regular workday, which was probably twice what I had on stock.
My SGS2 is completely unmodified or rooted, running stock KE2. The same usage patterns yield me around 85% battery after a full workday, and under heavy web browsing the battery life difference seems even more pronounced.
Factoring in the fact that I'm experiencing the documented battery drain bug causing aroung 50% of my battery usage to be taken up by "Android OS" and "WiFi Sharing", I would expect this battery life to improve quite significantly beyond this point once this bug is fixed.
tl;dr Battery life is acceptable, and much better than Desire. Expect it to be extremely good once a few software bugs are fixed.
Q: I WAS told this phone won't work on t-mobile. Only at&t.
Any 1 running it on tm? Advice plz
Vibrant

Hi there,
probably that request would make more sense in the developer forum but i didnt post enough yet
Actually i get insane battery batterylife with the bali 1.8.8 UV version, therefore i tried the non UV version with even more lowerd voltages via set cpu. it was stable but drained a lot faster. don´t know why.
so my request would be "pre-undervolted" bali kernels that might have even longer batteryliftime. Any hints on that? Someone who is able to compile something like this?
Best regards,
vibrantoparanto (from germany)
Hint' Bali X+Voltage control app= win !!!
Sent from my SGH-T959 using xda premium
^^ that is your answer....currently what im using
bali-x is what i used before - i lowered the voltages up to -150mv with some frequencies but it still gave me only about half the battery lifetime (less than 24 hours with moderate use) then i get with bali uv. What did you use to manually undervolt and how is your battery lifetime?

i hate to burst your bubble, but youre chasing a ghost. uv'ing will not produce very noticeable changes to your battery life, especially if were are talking baout different versions of the same kernel.
take a look at this: http://forum.xda-developers.com/showpost.php?p=21024393&postcount=8
Cannot agree with that. I tried *a lot* and flashed different roms and kernels for years now. With stock kernels i get up to two days standby with low/moderate use, with bali UV i get almost three days. I have no idead why, but at least the standby time differs dramatically between kernels. At least thats for sure - under load that might be another thing. But probably you´re right and its just a "good standby behaviour" which would hardly benefit from lowered voltages. Would be still interesting to try a hardcore UV kernel
TopShelf, it is funny that you posted that note/post b/c I was just getting ready to PM you that I put part of it in my guide like I mentioned a week or so ago and the apps too.
Take a look at the Guide and maybe you will find some answers to your questions.
If you want to UV to the max, then you will have to test that yourself b/c every Vibrant reacts differently to OC/UV. Step it down -25v each day (don't set on boot until you know they work) and see where it freezes. There are OC/UV examples in the guide but beware, they are both for MIUI kernels.
Is there probably any admin out there who understands what i talk about and can move that thread to the developer forum?
this thread belongs here, you posted in the right section. posting in development will not get you answers from developers, it will only get you yelled at by hall monitors.
it is a common misconception that "developers" ONLY visit the "development" section. this is far from the truth.
sorry to say, the reason you have not gotten answers isnt because you posted in the wrong section, but because requests like these are pretty much never honored. the reason is because if a developer decides to make a slight alteration to a ROM/kernel for a member, he will then get BOMBARDED by dozens of other members who have tiny little tweaks that they would like in their ROM/kernel
Still trying to bring back some life to my request with this argument: I just checked my girlfriends device (using zendroid 2.1.2 with bali 1.8.8uv) and couldnt believe it: 3 days and 14 hours since unplugged with 8% left. The battery is a stock 1500mHa. And as its my girlfriends phone its definity not "overtweaked and calibrated". Personally i care much more about standby time than super heavy usage (guess that should be fine then too).

Since you didn't like the answer you got, for clarification purposes you are basically asking for a dev to use their time for FREE an modified/debug/test a kernel with your requirements just for your own sake ?
i wanted to point out that this is a very interesting kernel with great battery lifetime. if you have a look at all the other threads of people desperatly trying to get 24h of battery then you probably wouldnt consider this request as "wasting free time of others for my own sake".

i can prove to you that UVing does not make that much of a difference. if youre willing to learn, try this little experiment:
-UV your phone using your current settings
-put your phone in airplane mode
-turn it off
-charge it to 100% while its off
-after it boots up, leave it in airplane mode and immediately lock the screen
-let your phone sit idle in airplane mode from full charge to death (record the time)
--------------
Once youve done this, repeat all of the above steps but with STOCK VOLTAGE. record the time.
now compare the two times. i would be willing to bet a large sum of money that it is not a notable difference, if any.
my point is instead of trying to convince yourself that your theory of UVing is correct, why not do a TRUE battery life test, and simply find out for yourself. you cannot run true battery tests while you are actually using your phone becuase phone usage is massively different on a day to day basis, even if you dont think it is, it is. there is background data, text messages/calls, notifications, etc. (which is why i said to put it in airplane mode, that way its just sitting there, with little to no variables)
i guarantee you that you are putting way too much thought into voltage settings. they do not help as much as people want them to. dont say im wrong until you actually try what i said above. although youre probably nto going to.

sorry, but this does not prove anything. what are you comparing it to? your phone? you cant compare her battery life to your own unless you guys have the same exact setup, same exact apps, and same exact usage habits, etc.
you are not going about this battery things the right way. you NEED to be willing to learn more instead of trying to come up with your own reasons in your own head as to why your battery gets a specific lifespan. If getting THAT MUCH more battery life was as easy as UVing your phone, dont you think the manufacturers would incorporate that and use that as a marketing strategy?? "New from Samsung, the Galaxy S III!!! This will revolutionize the mobile industry, curing the battery woes across that smartphone world...now with lower voltage for drastically improved battery life!! Pick yours up today!!"
It's not that easy, you need to read up on what affects battery life.
thank you for your thoughts topshelf, but as i posted earlier i am on that topic for years now and i really tested a lot. not as scientific as running phone on idle with different frequenzies but trust me: I know a whole lot about this topic. Also i share your thought that the voltage is not that important in the end. On the other hand i have to say you guys are quite ignorant about my observations i did earlier:
1. The bali-x kernel with manual undervolting provides (provable) worse battery lifetime than
2. the 1.8.8uv kernel.
Conclusion: As you say it is not that much about the voltage but about the way the kernels work as a whole. On the other hand it would be *very* interesting if the insane battery lifetime of bali uv could be even further improved. And no i wont put my phone to sleep for days in order to do scientific test (whoever is willing to i will donate - battery lifetime almost like astrology)
Last but not least: It is true that different roms provide significantly different battery lifetimes - for whatever reason. Some roms turn your phone into a handwarmer, others give you almost the standby times you were used from the non-smarthpones. And i think even the big companies have a hard time to write device specific code that is highly optimized - i mean you still get new devices with gingerbread instead of ics and so on. conclusion: on the software side *is* much room for improvement if it comes to battery lifetime on most devices.
just my 2 cents

Look at your post, you and "others" are asking for some one to do research and development on their free time and for free ? little selfish on you.
Look at all the kernels thread in the development section and read thru all the comments, I bet there is far more people whining and complaining about this and that, than providing actually constructive and monetary feedback to the developers.
Its not as easy as it seams, ecotox already tried this before with his ultra low power kernels and some reported great succes while others couldnt even boot, it goes down to the quality of the silicon on each particular phone. no dev has the time/money to develop such request considering all the different variables involved.
lastly if you are so fond on this idea, why dont you take the initiative and learn to compile and patch and make your own kernel ?

im not trying to pick on you, but this sarcastic response shows your overall attitude that jrafael is trying to make you realize. you want somebody to take time out of their day/night to do something for you...yet you arent even willing to let for phone sit for a day in order to learn a thing or two...letting your phone sit doesnt even take any effort, compiling a kernel takes a lot more effort than that
i hate to say it, but why should someone help you, if you dont want to help yourself.
thank you jrafael for the links - thats a great read.
@topshelf: still think you overreact here. For one who has developed it and has the workflow it is a matter of a few minutes - and no one is forced to do anything unless he thinks its might be worth it - maybe its inspiring? i am just asking. not everything idea must be done by the one who thinks about it. and the quote about battery life is true i would say - we are really lacking valueable info on battery drain with different setups.
from past week my phone is discharging very quickly and I changed different roms but no use and my battery stats is proper and I think my battery life has gone .....and should I replace new battery ? if so which battery fits properly .....as I stay in India no vibrant here .......but i9000 is there.........
If calibrating doesn't work then your battery could be bad. Other than vibrant the i9000 and topic touch 4g batteries work with the vibrant. Try ebay or amazon for cheap batteries.
Have you read this nifty little thread right here?
http://forum.xda-developers.com/showthread.php?t=1389069
Also, what rom are you running? I'm asking because if its anything JB, I wouldn't expect much in terms of battery life.
Also, what kind of usage does your phone get on a daily basis? Are you a light or a heavy user?
What kernel are you running? Which i/o scheduler and Governor are you running with?
OC? UV? The more info the better my friend ^^
There's all that too, much more helpful then my response. I just figured all the basics where tried already. I've had batteries mess up on me before. My original g1 battery got so bad that when I checked it, it was bloated.

Aha, both are helpful ^^ It's all pieces of the puzzle in my eyes lol
But if we can get a good idea of what the root of the problem is, we may be able to fix it without him having to buy a battery :]
I remember when I used to get 7 hours at best outta my phone, and I thought that was normal...but then I learned a few tricks, and
now I never get below an easy 24 hours on my phone, no matter what rom I am running. ^^
after calibrating it is working fine ..............thnx guys saved me from buying new battery
pretty much based on size and its waterproof feature. I do a lot of hunting, fishing and snowmobiling. I primarily plan to use this device for GPS and mapping and wondering if I can rely on it in favor of my Garmin Dakota 20. There's not much on the web that addresses its capabilities in this specific manner. Will I be disappointed? Are there specific ROMS available that might improve my experience in using the device in this manner? I'd obviously be interested in optimal battery life. I did order a couple of spare 1800mAh batteries and standalone charger in hopes of getting me through a solid day on the trail.

There are some roms, who improve battery life, don't know about gps. But if you install another rom, you will void your warranty and you won't be able to flash the specific original rom for your region, cause for most devices there's only the generic rom to flash (shouldn't be a problem if you have to take it to service, just that you know)...
If you want to use the active instead of your garmin, you will have to find a very good navigation app, because as I think, you need something for area where are no streets, too. And most navigation apps haven't got this feature...
I have an active myself. If you want to keep it down to it's basic functions (which is basically already set as an outdoors device) i would suggest that you don't upgrade to ics and keep the original gingerbread software which has far less battery draining than any ics based rom. About the GPS, i used it severalk times for travbelling and never for tracking so don't know how it works in deep thick woods, but always had speedy lock on and precise navigation. Unlike above user stated most navigation (one with offline maps would probably be best) apps are for trekking and offraod activities, what you can do is modify your gps.conf file to make it specific to your region or area so satellite lock time will be much improved. Just search the forum for gps speed fixes, there's also a patch for agps to help increase satellite locking time.
I own this phone and wanted to do the same as you.
All setups i tried were not stable. sometimes the external power cable got disconnected, sometimes just the app closed.
after months of testing, i reverted to gamin products as they offer a much more rugged and robust hardware. I never managed to track > 20 hours on my active-phone.

Thanks for all of your input folks.
I did receive the phone on Friday and had a chance to check it out over the weekend. My first impression is that it has a comfortable size and mass to it and I do not mind the screen size at all. It seems quite speedy and the (Gingerbread) OS operates like butter. I did have difficulty getting the GPS function to lock at first. After prolonged attempts, it wasn't until I installed an app called GPS Test did it finally lock - not quite sure what the difference was, perhaps AGPS may have been responsible. Since then however, I have been attempting to maintain GPS-only locating as I am certain that data would not be available in the majority of my usage areas. I looked at most of the GPS Mapping/Tracking apps and settled on the paid version of AlpineQuest - excellent app. I got my waypoints from my Garmin loaded onto my SD card and was quickly navigating the trails in the woods behind my house. Great stuff!
I got just over 8hrs of solid use out of the first charge on the stock battery, so the phone should keep up with a full day on the trails. I have also ordered a couple of spare batteries and standalone charger for backup. Since this first day of use, I have been using the GPS Test app exclusively to verify my satellite lock prior to using AlpineQuest. I did notice that after prolonged non-usage or following a charge cycle I did have some difficulty locking on to the satellites, however each time it was solved with a phone reboot - after which the GPS Test app would lock on within seconds (even inside the house). Each time I was in airplane mode with WiFi off. I will have to monitor the satellite locking for consistency before I am all in with this device but so far I am quite please with its (stock) performance.
the phone & the user may be active, but the battery is certainly not. the display is not that bright under bright sunlight situations :X
hi, i have the active as well and so far i am pretty satisfied.. not VERY satisfied due to Battery life.. but without that issue, I am satisfied...
I have dropped this baby 4 times already on concrete (2 waist level 2 chest level) and the phone just bounced without any cracked screen (it does have some dents on the silver lining around the screen though), but i can guarantee that this phone is shock proof because on those 4 times, the phone did not even turn-off or restart or even battery breaking out from its case...
I do not do trails but so far, the NavFree app has been very good to me with my driving direction needs... easy locking with GPS and pretty good directions...
Try also searching for build.prop tweaks in the development area of this forum because i think it can help in the phone's performance and a little bit of battery life.. i can do intermittent non-heavy image/flash website surfing and the battery could last more than 8 hours and if I just have my phone on stand by (just waiting for messages and calls and reply to them) battery could last more than 24 hours...
I have to ask you though, were those 1800 batteries better than the 1200 ? I was also thinking of buying spares...

I haven't got them yet, but these are the one's I ordered.
I'm on the .62 build so looks like I have to flash an earlier firmware just to get root. I'd really like to get rid of some of this extra crap and get link2sd going. If you are rooted, what firmware are you running? I just hope the GPS performs just as well on an earlier build.

you have to tell me if you notice some increase in battery life with those 1800's...
regarding rooting, i followed this procedure with no problem: http://talk.sonymobile.com/message/241059
just follow it step by step.. also, if you are not aware, you have to flash the kernel using the flashtool before you can flash the rom through CWM.... in anyway, you should not be afraid of bricking your phone because I was able to always restore my phone through that link's procedure.. however, pls do not take my word on it because what works for me might not work for you even if we have the same phone... we still might have a different stock.. so rooting your phone is always at your own risk (my disclaimer, hehehe)...
regarding rom, i find the free experia rom's quite good... after initial loading of the rom, i got more than 400mb free internal space.. so they did remove a lot of bloated apps that you dont really use...
just as side note: i installed cm10 fxp138 on my active and the battery lasts for 36hours and more. i really like 4.1 jb.
Update
OK, so I am rooted and remain locked. I ended up flashing stock 4.0.2.A.0.42 and then this ROM:
ROM][GB][ALL MDPI] HASA v5 [2.3.7][27/9/12]
My prayers have been answered! This ROM is fast and lean! Thanks very much to sandy7 for his work on this! I followed his instructions exactly as in his first post, however did not need to install the revised camera lib as I had no issues with the camera. I've had absolutely zero issues and love the speed.
Now for the battery life. I finally got the spare batteries I mentioned in the previous post (shipped from China). My initial observation is that these batteries smoke the stock one by a large margin. I still need to spend a little more time on this ROM to be certain. As mentioned before, my goal is to replace my standalone GPS unit with this phone. I am not using phone or data, so I am in airplane mode all the time. I am using wifi a bit. With the stock battery I got about 1 day and 12 hours of standby and light use on wifi and gps with 10% remaining. On the replacement battery I got 3 days and 16 hours with 35% remaining before I decided to try the stock battery again. The stock battery began to drain as soon as I put it in and was down to 85% within the first hour. I don't know, perhaps these stock batteries are junk? I am open to suggestions on how to properly do a test and comparison.
omg.. really? so those china batteries work for you? damn.. I want those.. i will buy those..
Just wondering if the differences in the two are normal.
I owned a SGS2 for a long time, and the battery would sometimes be just awful. There were days when it would drain 1% on standby, and then days when it was like 5-7% on standby - which is pretty bad for not using the phone at all.
I finally gave up on non-nexus phones and got myself a gnex and its freaking awesome. On a typical day, i leave for work at 7, and get home at 3 with 70% left - with some use.
I switched back to my SGS2 to see if there was still a difference even when running a newer/better rom, and battery life still seems pretty bad. I was at my other job today, and my Gnex will usually drain 15% over 8 hours, today my SGS2 drained 70%
Is this normal? I have bbs and cpu spy installed, and will post results after work tomorrow if anyone is interested.
I was planning on giving this to my mom as her first smartphone (i thought the lower DPI would be better for her eyes), but now im thinking i should just sell this, and then use whatever i get to put towards a Gnex.
Next time man just post one thread regarding your questions and issue. No need to make one here and one in general. And to answer your question about battery life it depends what rom yer running and what apps u have installed. And I suppose how u use the phone as well, referring to whether u listen to tons of music or mainly for calling, either way good luck, happy flashing.

Identical everything with the exception that the SGS2 is AOKP, and the Gnex is paranoid android. When i installed AOKP on my SGS2, i literally sat there and made it so both phones look about identical - with the exception of rom specific things like the notification menu and stuff like that. Same apps, same settings, same homescreen setup, etc etc etc.
All things being equal - is the gnex that much better on battery life?
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.

Do you calibrate battery after every ROM change?

Can you please point me in the "settings" direction? I think I'm doing all things right, going real low on app usage, sync-ing of apps, screen settings, etc.

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?

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.
