1.flash Stock Samsung Rom I9100XXLPJ from samfirmware. (it is 4.0.3)
2.Flash XXKL1 Modem. I searched alot about Modems and found alot of people saying that this modem is good for battery. and it is latest stock modem.
3.have to give up slim ICS. and move to Hydra2aokp rom(4.0.4). with hydra kernal(came up with The rom).
4. i have not touch NS tools, not any performance settings, not even init .d Scripts.
Setting my desktop, and playing around the rom for 1 hour. with screen timing was 52 mins
and after full charge, and using for 1 hour(Setting my desktop, and playing around the rom for 1 hour. with screen timing was 52 mins). my Battery Stats looks like this, and Stil STILL STILL OS bug
