So ive been reading that a lot of people have been having problems with their battery taking too long to charge or that their battery drains when their new ipad is asleep...i had both problems My battery took over 8 hours to charge from 20% to 100% and it drained around 3-5% overnight...i was about to return the ipad to get a new one but then i tried the method of comopletely draining the battery then charging...and it worked! It now takes around 5 1/2 hours to charge my ipad from completely dead to 100% and when it is sleeping overnight, it stays at 100% the battery life is also much improved. I highly suggest everyone try this...completely drain the battery and then charge it back to full and time it. It worked for me...maybe it can work for you! NOTE: the only other variable was that i had been using another usb cable from an ipod touch instead of the new one that came in the ipad box...when i did this test i decided. To use the new ipad usb cable...idk if this makes anydifference at all but just wanted to throw that out htere as an option. Hope this helps!!!
