I've been wondering why my tablet goes from 100% and goes down as soon as I unplug it. It goes down all the way to 89% and everytime I try to get it to a 100 it keeps doing the same thing. I've tried everything unistaling apps, deleted images from my gallery, I also did a factory reset but nothing worked its been happening for a month and a half now. Any suggestions?

a battery that drops charge percentage immediately after unplugging would indicate a battery dying. The charger places it in the 100% mode AND supplies power for operation. As soon as you disconnect it, the internal resistance of the battery causes a lower voltage and the indicating circuit thinks it is discharged. Plan on replacing the battery in the near future.
