lately the battery life of my phone has reduced considerably i fully charge it at night and when i wake up its reduced by 20-25%. and when i check usage and standby times its almost same or there is a bit of variance. also when i switch it off, it switches itself on..i tried searching for the solution but can not find it. i wonder if anyone of u know. i am guessing there is a process running in the background but i duno how to stop it or even how to check what processes are running on my phone.
