    My phone's just reached its 20% battery warning for the day so I checked my usage to see how I did today. It says 3:43 usage and 15:21 standby. Seems pretty good, except I pulled it off the charger about 15 hours ago. So how does it figure the usage number? Is it time since the charging was completed, which would be pretty close by my estimates? Or is the standby time the more accurate number and the usage is part of that? I thought the two numbers summed together was time since unplugging the charger, but that doesn't add up.

    I get over 40 hours standby with usage. :)

    Here you go after my first charge and now my 2nd charge before I placed it on charge this morning.

    Standby includes usage. So it's the total amount of time your phone has been off the charger. I don't know why they called it that but obviously some flip chart some place made it feel like that made sense.

    Thanks, Ottergal.

    Shoppy: What features do you have enabled/disabled to get that much battery life?
