I bought an iPad3 two years ago and I believe the battery has recently started to malfunction, it barely lasts a whole day.
a) Is it possible to change batteries? If so, what's the best way to do it? And how much will it cost me?
b) How many years is it supposed to last?
c) I read something about a new smart cover for the iPad that also recharges batteries. Is this already available?
Thanks in advance!
