samsung galaxy tab 2 7.0 battery charging/draining really fast

[AC Question]

I recently broke my samsung charger for my galaxy tab, so ive been using my ipod one, until the replacement came.
At first it was fine then, after a couple days, i realized that it was charging really fast, like from 1% to fully charged in about ten minutes.
It was draining at the same rate.
I thought this might be because of the charger so i stopped using it.
Today my replacement arrived and i plugged in my tablet, only to find that the exact same thing happened.
Does this mean the battery is busted or is there any way to fix this??
Thanks in advance!!

Welcome to Android Central! That could be a sign of a failing battery. Does it still discharge at the same rate, or does it discharge really quickly?
