I have an android tablet jelly bean, I bought it 2 months ago and it was working fine until recently when it started acting weird as it keep turning off itself and showing inconsistent battery levels eg. 22℅ then 90℅ then 0℅.
Even if its fully charged, de tab will only work for few minutes before it shut down and when I restart it, I will notice de drop of battery level from 100℅ to 20℅ and then it will work for couple of minutes and turn off again. Its really annoying.
I have tried to calibrate the battery, factory resetting and cleaning the battery and its ports but with no success.
Any help please?
