I have been having a few problems regarding the battery life on my new iPad. Firstly, When I charge it, it reaches about 96% then the sign changes from the "charging state" (the lightning bolt) to the charged state (the plug symbol)...However, it keeps charging. (The numbers keep increasing.) Secondly, as soon as I unplug my iPad from the charger, the percentage decreases from 100% to 99%. Is this normal? And thirdly, the battery life decreases rather fast...like in 5 to 10 minutes, one percentage is lost and only one app is open. (IM Pro). Can someone help me with my problems here?
