Before the ICS update on Monday, my phone (on GB) never had problems with batter life. Last two days, it is terrible. I checked background running programs and everything seems to be fine. The batter is draining pretty fast. Not used much except few quick calls and browsing for not more than 15 minutes and the battery came down to 20% by late noon. Earlier, with the same usage my phone battery used to last until 2 or 3 AM the following day. Anyone having the same problem after official ICS update?
Will it help if I buy an extended battery? Please advice.
