All of a sudden my N900 battery is draining really quickly. I just started happening and nothing has changed. The only thing i could think that could had caused this is my phone died over night and i charge it back up and tried Wind Mobile network with their simcard.After those two events my N900 battery is dying quicker than usual. I can't even get 7-8 hrs out of mines anymore. It is not even multi tasking as hard as before and its not surviving my daily use... Whats going on?
