Apple responds to iPad battery concerns
When your iPad says its 100% fully charged it actually might not be. IPad users have been very concerned because they have been hoping to get the most out of their iPads battery. When the Apple device says its 100% fully charged , it actually releases a small percentage of the charge, then charges back up, repeating this process until you unplug it. Apple says that when it reaches to this point you are guaranteed 10 hours at least of battery life.
