We have 2 8350's. They have to be charged 2 or 3 times PER DAY with light or sometimes NO USAGE at all. Whats up with this? Both the phones are the same. I made a call that was under a minute today and sent a few texts, that was all, and my battery is half way down. My old phone under Sprint (which I thought was bad) only needed a charge every 2 days or so. My aunt who uses her 8500 constantly says she only charges it once a week.
