Re: Why does my battery life dies and will not fully charge

How old a phone? If it's more than 2 years old, or you abuse it terribly (discharging it all the way every time), it's probably time for a new battery. (If you abuse it you can kill it in a few months. Lithium batteries should never be discharged below 40%.)
