Battery life is terrible now, can barely get through a day when I use to be able to get through two on IC, don't really make calls often, but so far drops have not been an issue. Probably going back to IC because the battery life is just utter sh*t.
I don't spend much time on my phone so my battery life is usually about 70% at the end of the day. Wifi is on all day. You might try running "Clean Master" and make sure "Autokill" is on.
