I hypothesize that you may not be charging it up fully?

I have an FM Recorder, and when charging with Rockbox, the battery display
hits 100% _long_ before the battery actually fully is charged. At first I
thought the battery was draining quickly, then realized that I was not
charging it fully. Does the battery seem to charge much more quickly with
Rockbox than the archos OS?

My method is charge up for a while after it hits 100%, then reboot without
the charger. The battery charge figure after reboot will give me an idea
of the real charge, and then I plug the charger back in and repeat until
it displays a charge I'm satsified with after reboot (>95%).

There is a mailing list thread about fixing the display to tell you when
it really stops charging. I haven't a compile environment for it at
present to use it myself, but perhaps it will be in a daily snapshot soon?
