Really enjoying my new iPad. My first ever iPad, it looks beautiful, runs smoothly, none of those crazy yellow tint issues others seem to be having, etc... But Ive quickly noticed just how long its taking the thing to charge. If I dont use it, and just leave it charging, it charges about 1% every 5 min or so? Maybe longer? But if I'm actually using it, while its plugged in, I dont see it charge at all. It stays stuck at whatever percentage its at. I wonder how long it will take for full charges?
