I've recently moved into the dorms here at UCLA and all of a sudden my iPhone 4's battery life utterly sucks. When I was living back at home my iPhone, at the end of a long day would be at like 40-ish%. Now, I'm lucky if my iPhone is still on by the end of a short day. There are other dorm and roommates here w/ iPhones on AT&T and they seem to have better reception all around. My iPhone here keeps switching from 3G to that little circle signifying the internet is dead slow. Obviously its the iPhone looking back and forth for a reliable signal, though it seems I need a solution for living these next 9 months at the UCLA dorms. Any advice is appreciated.
