I have been having a very similar problem. The percentage full reported by gnome-power-manager was around 6-7% while the time remaining would be at a reasonable 2-3 hours. I also noticed that "Energy when full" was reported at 643 Wh (with "Energy (design)" at 50.2 Wh).

I see a similar discrepancy in the DevkitPower.txt attached by the reporter:

    energy-full: 1357.04 Wh
    energy-full-design: 50.2 Wh

I found this: http://ubuntuforums.org/showthread.php?t=736347 -- david_edmundson advises the following for a similar symptom:

  "It's a known hardware bug. Affects OS X too.
   The fix is listed on Apples website somewhere.

   Shutdown, take the battery out, and disconnect the mains. Then press and hold the power
   button for a while. Reassemble, and all will be good."

I did this, and now the numbers reported by gnome-power-manager are reasonable. (energy-full at 51 Wh).

What I quoted above states that this is a hardware bug, but I haven't gone any further to verify that.
