Sometimes my battery meter will show the plug to indicate the fully charge status even when it's not. Even my battery apps tell me I only have 90% charge remaining. Once the battery was only filled about 1/4 all the way yet it still showed the full charge icon. The main problem with this is that my iPod really thinks the battery is full so it stops charging. I haven't done any jailbreaking stuff on it so idk what's going on. Can someone help me please?
