I've changed the level calculation. It should now show 100% after
charging and not going up and down so quickly.

You can select the battery capacity in the menu since some days ago. The
runtime also depends on how much the drive is working (= bitrate) and if
you turn the device on and off often.

This should be "fixed" now.

Sorry for me getting excited. I now see that the battery level how it
was displayed could confuse other users, too.. I hope this is better
with my changes in the actual cvs version.

P.S. look into the actual docs/CHARGING_ALGORITHM if you're interested
     in details
