IPad shows low battery when fully charged (PROBLEM SOLVED)

Finally solved the problem. I use to leave my IPad charging all night and in the morning it would sometimes show low battery even though it was fully charged and it would take multiple attempts to reboot, I was about to throw it away. The solution was simple, don’t let it re-charge to 100%. Now I take it off the charge before I go to bed, before 100% is reached and it starts up perfect every morning. I wish apple could try to explain this one.
