Once a month, you should perform a full charge cycle to ensure proper reporting from the battery indicator. To do this simply charge the battery to 100% and then use your iPad until the battery completely depletes (iPad turns off automatically at 0%). Then charge as you would normally do.

as i know it is better non let the ipad batery below 20%.
