All of a sudden the battery of my DNA is draining much more quickly. For instance, yesterday evening I charged it to 100% and then unplugged it overnight. I use Juice Defender and it turns off everything overnight - no account checking or syncing occurs. This morning the charge was down to 66% Normally the phone would only lose 3% - 4% overnight. Battery usage under settings shows the kernel at 70%. All of the installed apps show very little usage. I've rebooted the phone a couple of times, but that didn't help. Any suggestions as to how to troubleshoot this? TIA
