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". -- battery remaining time https://bugs.launchpad.net/bugs/441096 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
