My phone keeps shutting down and won't power up. I went to bed last night and the battery was at 90%. I went to check my phone a bit ago and it was off. I tried to power it up but nothing happened. It was like the battery died. I plugged it into a good charger and after a bit it still won't power up. It hasn't been dropped or dunked and has been working well till now. It took an update the other day and a few things vanished but it has been working. Has anyone else had this happen. The phone has been in use since March and pretty much never gets shut off for any length of time other than rebooting once in a while. It has never been run till it dies and I don't let the battery get below 25%. Had to switch back to my old Commando till I get another one.
