I recently got my 3g iphone replaced for a brand new one, and at first when i sync'd my new phone i didnt get all the music on it, however, it still had all my apps and contacts and such. The battery laster a good 5 and a half hours of normal use (texting, mail, safari, few calls) before giving me the 10% warning in which i charged it. I charged it fully, sync'd my songs, and after that, ive only been getting about 3 hours off of my battery. Now i know its not the battery but what could be the problem? my settings have remained identical : 3g on, push off, location on, wifi off, brightness ~20%. I dont understand that how after syncing my songs (not even my apps) that the battery could now be draining faster. Any Ideas?
