I can confirm this; gnome power manager seems to calculate the battery lifetime by averaging discharge rate over a period of time. It seems that this value is also taken into account while the laptop is still plugged in. This is leading to a higher battery lifetime estimation. When you click on your battery symbol directly after unplugging, you can see a discharge rate that is too low.
Discharge rate in the ubuntu-notification shows a different, more accurate value.
This bug is not so bad as the estimation is updated soon, but this prevents the system from being "perfect".
