John Brownlee reporting:
“I measured the power actually drawn by the AC adapter and found that the new iPad continues to charge for up to 1 hour after it claims to reach 100%,” says Dr. Soneira. “This affects the battery run time if you stop charging when it says 100%.”
I’d love to see the actual research here. I have only had to charge my iPad once since getting it so I can’t say whether I have noticed anything like this. Obviously it takes longer to charge, but not really being charged when it says it is? Sounds dubious to me.
