Last Monday I slipped my Razr into my back pocket and hopped in my truck, got home and the display was shattered. Went to a corporate Verizon store and got a new phone. Now my battery(unplugged at 8:00AM) is 20% at noon and dead by 2:00PM. Should I take it back or does it take a while for the battery life to improve? Has all updates. I'm working in Akron/Canton area and the phone isn't struggling for signal. This is frustrating.
