Hello guys, I have a problem with the battery in my galaxy 2.

Previously i had version 2.5.11 and when I fully charged my phone I realise that my phone was charging without the charger and in the lockscreen says charging. I went to 2.5.18 but the problem didn't fix.

I've also tried fixing the problem with battery calibration but the broblem still exists. After a few hours my battery drains from 90 per cent to 30 per cent. I also changed a battery.

Thank you in advance
