Something weird with my battery just happened. I've never had any problems with battery life, and today's not been bad either. But it's been off the charger since 7am this morning (12 1/2 hours ago). At 7 pm I got a warning saying it was at 20%. I am sitting in the living room, so I just left it beside me. Nothing was open, though my WIFI was on, so I turned it off. at 7:20, it warned me again, saying it was down to 10%. Seemed weird, so I did a reset, when the phone came back on, it gave me another warning, and when I looked at the phone, it shut off. It won't come on, of course, so I just started charging it. Anyone else have this issue?
