I have a samsung duos i9082 without root. the battery life drop 10% - 50% when remove and reinsert the battery.
So my question is. is this a battery problem or devices or software?
Does replace a new battery fix this issue?
update question
The first drop is remove and re-insert battery. The second drop is from 15% - 0% (less than 5mins) 48% usage by screen.
