You could replace the battery but to increase the mAh it is not possible

Hello, Even I experienced Faster battery drain after updating to Jellybean 4.1(6.2.B.1.96). But after a week, battery performance improved. So wait for few days, so that new OS settle downs. Make sure that certain buggy apps don't extensively drain the battery.
