So I got it and put it in the charger at 25% at around 9:15pm. 3 1/2 hours later I turned it on and the screen and touch sensitivity seemed off and sluggish. So I decided while it was plugged in still charging at 77% to play Drag Racing for 5 or 10 min. When I exited the game after that amount of time it was at 100%.... what's the deal? No way that could happen. So I rebooted it and it still showed 100% but on boot it just showed the battery on the screen. Did a battery pull (much easier to get it out than the standard, no keys necessary) and it came up normally at 96%. Now it's to 97%. Could it have been malfunctioning and been fully charged in 3 1/2 hours? What happened?
