Just thought I would pass this along... First battery would completely discharge after about 8 hours of very light use, second one was the same. Both times Verizon was very helpful and swapped out the battery. The interesting thing was that both times they tested the battery and said it was running too high a voltage. The second time i asked and was told it should be running between 3v and 4v , but mine was above 5v. So if you're having issues, and have a multi-tester, you might wanna check it. It should help diagnose whether it's a hardware or software issue.
