I have a Samsung galaxy s3 mini and every time my phone battery is like 50% amd i do someting on it like call someone,take a picture play a game etc… It turns off and even if it says I still have like 40% of battery left and then i turn it on again and it says 0% and I put it on charge and if I don't it will turn off again and when Iput it on charge (after it turns off )after a few seconds it says my phone battery is on like 60%… I was wondering if it was a virus or just my battery going crazy?
