Hey guys. Since I installed 4.0 GM my battery drains really fast. I don't know what's wrong. It worked fine with 3.1.3. Could it be Yahoo Mail, Location Service, Push, or even Persistant Wifi feature.. ? I don't really now, but it's really annoying. Jailbroken or not, it happened with previous betas too. So. Any help ? Thanks in advance - Please Register or Log in to view images Littl' edit: Well, disabled Location Service, Push Mail (Yahoo!), lets see.
