Several users have reported that their iPad (a) does not charge, (b) charges very slowly, and (c) does not charge fully when it is plugged in to a power outlet. The new iPad has some new impressive features that consume a lot of energy. Apple increased the size of the battery compared to the batteries in the first and second generation iPads. Thus charging the new iPad 3 is slower than iPad 2. It may take 50-60 minutes for a 10% charge and may take up to 8 hours to fully charge.
