I recently acquired an HTC Desire Z / G2, and installed Cyanogenmod 7 onto it. Something I've noticed though is that sometimes the battery drains very quickly, and sometimes it does not. Since I have a tendency to charge the battery very often, even when it has not discharged much, I get the feeling that the battery stats are not correct.
As I recall, before resetting battery stats, I should make sure the battery is at 100%. My question to that is, how can I tell if my battery is at 100%? Is it when the LED power indicator is constantly green? When Android reports as 100%?
