My wife's iPad Mini 2 has been charging for about eight hours and has reached 32%. I switched on Airplane Mode as a result of an internet search and it is at 56% after a further hour. My question is this, though: my normal daily broadband data usage is in the region of 250MB. Twice recently, it was 1.72GB and 3.66GB. I have had my suspicion about the iPad Mini using data. I have looked at my data usage today. It is 650MB so far - that would be up to two hours ago and I have hardly used my PC, the only other device in the house. Is it conceivable that the iPad Mini is using broadband data somehow while charging?
