Dont waste your time or money on Battery Doctor. Causes iPads to take OVER 24-hours to charge from 20%. Annoying that you have to open the app for it to understand that youre charging your iPad, and even then, it tells you that you didnt open it and it asks if it was charging longer than 6-hours. Dumbest app out there.
