I've had my iPad for a few weeks now and have had no battery issues whatsoever. In fact, my battery has performed way above my expectations. I have made a conscious effort to never leave it charging all night (despite people saying it doesn't matter). However, I accidentally did end up charging it all night recently (it only needed 10% when i plugged it in) and since doing this I have noticed that my battery drops much more quickly than it used to even though i am using it the same amount. I'd even say that the battery dropped significantly faster than it used to. Could this have caused it or am i just experiencing the normal wear and tear of the battery?
