So I just bought the AIR and I'm like stoked and all about it but today is my second day owning it and decided to see what it can do. I was at 24% and was playing scrabble with a friend. I turned it on and it charged until about 90%. I thought it did 100%! is this because I was playing a game on it that it didn't charge all the way? If I wasn't using the phone would of it had charged more? Also, all four dots were lit up before I turned on and when it was around 60% it only had 1 dot left on the case, what's going on?
