I don't know why but yesterday morning I was going ot check my email and I got the popup to upgrade. I clicked yes and it went through the process. That was at 7:00 a.m. The phone had 100% battery per my meter even though I took it off the charging cord at 12 something the night before. Usually is at 90% after I get the email. I didn't look at the phone again until 10:30 a.m. to finally get my email and the meter said 5% left.
I didn't have a charger and was going to be gone for the day so I went to the Sprint Store to tell them what happened and maybe borrow a battery while they charged mine and I'd be back in a few hours. They are always nice at this store and she went in the back and got me a fully charged battery and said not to worry about it she'd just keep mine.
Well, I haven't had that problem since so maybe it was just a coincidence that the battery went bad at the same time of the update or if the update caused it. I never get good battery life out of the Moment (and that goes for the new battery either, but never saw anything like yesterday. Anyone else have the same problem?
