I have a charge and love it. It has been using more battery recently, and it was suggested to try spare parts. No one in the charge forum seems to know what this means: Battery history/network usage since last unplugged: "0" is a HUGE blue bar, dialer is almost as huge, and android system is half the bar. What does any of this mean? What is "0". And why would the dialer be using network? Thanks in advance for your help.
