That is 'stand-by' time. If I'm bouncing on and off the device, isn't the the overall time of usage reduced?
I used to leave the edge on all of the time (stand by/actual usage) and just left it plugged up when I wasn't using it. After about a 6 months or so, the battery failed - the device would not start with the battery alone.
I don't know if my behavior contributed to the battery's fate or not, so I'm trying to avoid over recharging the battery, if possible.
