I think that the charge is meered based on voltage at the battery. So, with the charger connected, the voltage is at full even though there is still capacity in the battery.
This is my experience as well. [Kobo Touch] You cannot accurately tell how charged the battery is when it is taking voltage from the USB. It appears that there is no special circuitry to take account of this. The battery is fully charged if it reads 100% when plugged in, AND still 100% 10 seconds after your unplug it.
