Thought about taking my new iPad back but I loved the new features so much that I didn't want to. Just like anyone else i felt my new iPad getting too warm battery seemed like it did last long. So I decided to try something. My second day of owning my new iPad I drained my battery down completely during the day then fully charged it back up at night. I did this for a week. Since than I can run my brightness at 100% without getting hot my battery even last like it should now comparing it to my iPad 1 there both equal now. Maybe you guys should try this!!
