iPad charging help!!!
So recently my iPad 2 was kicked (not very hard) while it was in my backpack, I noticed nothing wrong later that day it wouldn't charge or be detected by iTunes, I noticed when I did charge it it never said it was charging but it did extremely slowly then it burnt right through that new charge, I assumed I had broken a pin off or something so I got my dock connector replaced and it worked for maybe two days and now it's doing the same thing again, I took it into apple and one of the geniuses worked on it gave it backing it charged for maybe 10 minutes and quit again. I have used 3 different chargers and different outlets. Any suggestions? Thanks guys
