I've seen quite a few posts with people asking what to expect from battery life. The responses were typical... "I get __ hours and I only run this and that and such and such for so long..." but no one has posted anything yet that gives others a baseline to run with. ... until now. I left my phone completely alone this weekend. No data, No calls, only one or two incoming texts... unanswered. The phone sat totally idle. How long did the battery last? 39 hours. so there you have it.
