first off, if you are using a JB rom, there's no need for battery calibration as it resets automatically everytime once u recharge it

second, are you using the latest leaked JB? if yes then there's a media storage issue (AOSP based roms)
where it'll drain a huge amount of battery

third, battery drop could be due to your apps installed also.. does it have wake issues?
you can check it with BBS. (better battery stats).. marketlink need to play, but if u find it on XDA, its free. only for XDA users..

well, my battery is pregnant but if i left it on overnight with wifi on. it does drain at least 10% cuz it didnt went off by itself, i set that it will auto off after awhile under its wifi settings but it doesnt seem to work.. 

for me, my screentime with about 58 minutes after unplug from 100%.. (used for 1 hour straight with wifi).. battery only dropped around 10-15%

ofcuz since its at night i set my brightness to the lowest.. else i'll go blind while im using it on my bed.

can't seem to find Malaysia i9100 stock image there. All china, italy etc.

This one SME set unroot. Still ICS and waiting for official JB update. Not sure about the wake issues, i'll give my phone 3 days if the battery issue still there, i'll inform here. Thanks for responding

ICS ehy?
im already on 4.2.1 .. but felt like reverting back to touchwiz when alliance comes out with v7.. i think i'll just sort my DPI issues with 3rd party apps.

have been using AOSP for more than a year. bored of it already..
since touchwiz implemented quite a number of features that AOSP didnt, felt like giving it a try.

How come you on JB now? I've search online says Malaysia still waiting for JB official update. And i've clicked software update in my S2 but no updates found. Did you root your phone? Btw mine is I9100G.

im not using official
its nightlies 4.2.1
pretty stable enough for nightlies build.

alot of AOSP/AOKP/PA roms on XDA are now based on it..

but alliance rom will be based on LS8 for the upcoming v6.1 and LSD for v7 (based on his post)
both 4.1.2 though as they are touchwiz roms.

My S2 still 4 months old, still under warranty, still virgin . Dun plan to make any changes of firmware to it. Guess i have to wait for official update then 

facing a problem now. I downloaded CM10.1 for SII. But the stock OS crash and doesn't manage to get into OS (CWM still can)

I want to put CM10 file and use CWM to flash. How can I access the internal memory to copy over yeah?

you can mount usb storage from cwm menu can copy the file over.

mind to tell me which to click? is mounts and storage > mount usb storage? it come up unmount and go back

yes. connect the phone before click it. leave it there until you want unmount then click the "unmount and go back"

nothing come up as well. Do I need install some kind of driver? I already have Samsung Kies thou

someone answer me please..

i just updated my paranoid to pAranoid PIE 2.99,but the problem is that some of the app suddenly unsuitable to my rom ,is changing rom meant yer change the software?so the app could not suitable to yer current rom?any other way to fix that?

i flashed my 1st custom rom after 2 weeks i bought it. hahahaha XD

like they all said, once u go custom, u will never go back. i guess that's kinda true.

yeap.. been a long time CM/AOSP/AOKP user..

feel like trying out touchwiz once again.. but alliance still haven update their rom yet :S

already waited 2 days since they gave out the "green light" that there's gonna be an update..

cuz i dont wanna flash and use for 2-3 days then got new update again.. wanna start fresh and configure everything first. hahaha.

i felt that the new touchwiz by samsung is totally different now. unlike in the GB days..
this one implemented so many features that the AOSP based roms just couldnt have..
