I am having some issues with my phone's battery. I have twice run the battery down to zero in an attempt to get a full, clean charge, but when i plug the phone back in to charge, it shows around 53 percent charged immediately, and then when i unplug it again, the battery lasts for a period of time after that.

I recall a command, or number i could call that took me into the battery settings where i could 'reset' the battery; this worked the first time i needed to do it, but i am unable to remember the command.

Any help i can get would be most appreciated!
