I tried to pull it out many, many times - nothing helped. I don't have a car charger for this phone. I am using USB and wall charger - depends which one is closer. The battery drains soooo fast when it is like this aswell. I'm going to try discharging it completely and then charge it again, maybe this will help. It can't overcharge, can it?
EDIT: I discharged the battery and it didn't help.
