Comment 1 for bug 473552

This bug seems to be related to other simalar issues such as Bug #393008
I notice that the power manager applet doesnt recognise the AC has been unplugged. After running like that for an hour or so shut the machine down. Restarted later in the day and the indicator now correctly reported battery power and correct battery level however this soon changed to telling me the battery was almost empty (7% or so) but still with more than 30 min run time remaining.

On closer inspection running $ devkit-power --monitor-detail
The battery was incorrectly reported as

energy-full: 88.7883 Wh (or there abouts)
energy-full-design: 26.64 Wh

I didn't get chance to copy this as my machine shut down seconds after I noticed this. The machine is now on charge and looking at this again I notice the charge rate is extremely high which cannot be correct

  History (charge):
    1258072896 50.999 charging
    1258072865 50.609 charging
    1258072834 50.268 charging
    1258072803 49.683 charging
  History (rate):
    1258072896 715.928 charging
    1258072865 715.950 charging
    1258072834 715.850 charging
    1258072803 716.771 charging

The charge graphs are also all over the place. see screen shot at http://www.flickr.com/photos/bshephard/4098866663/

Bugs in Devicekit-power seem not to be handled by launchpad but I don't see any way to record the bug upstream either. Documentation also seems to be incomplete
