When I unplug AC, I get a warning from g-p-m that I only have 3 min.
remaining time left, although my battery is fully charged and usually
lasts for ~2-3h.

As you can see from the attached log, it takes a few seconds, until dk-
power reports plausible values for remaining time.

I'm not sure what the best course of action here is. Usually introducing
heuristics causes more issues that working out why the hardware / kernel
reports invalid values.

Maybe the heuristic can be as simple as simply waiting for 10 to 30 secs
after unplug before reading the values and just use the old values from
before the unplug for that time frame

Title:
  upower (devkit-power) reporting bad data when AC cable is unplugged

Status in DeviceKit based power management D-Bus backend:
  Fix Released
Status in “upower” package in Ubuntu:
  Fix Released
Status in “upower” package in Debian:
  Confirmed
Status in “upower” package in Fedora:
  Unknown

Bug description:
  Binary package hint: upower

  upower reports enormous energy-rate for first time after cord is unplugged.
  GPM reacts on this first event not checking subsequent events.

  This bug is started because I found no ways to collect data for bug #473552.
  I have no devkit-power package.

  === EFFECTS ===

  This is the underlying cause to gnome-power-manager immediately
  reporting critical battery after unplug even while charge is good. It
  is not a gnome-power-manager problem, the root is here in upower.
  Please do not report bugs against gnome-power-manager for this!

  To workaround the effects execute:

  gconftool-2 --type bool --set /apps/gnome-power-
  manager/general/use_time_for_policy false

  (from <https://bugs.launchpad.net/ubuntu/+source/gnome-power-
