You might want to set the Idle Off Timeout. On my player it located at
"Menu -> General Settings -> System -> Idle Poweroff". I have mine set to
10 minutes, which for me is a good compromise between power savings and
convenience. If I'm in a power-tight situation (like camping) I'll bump
it down to a 2 or 3 minutes.

You might try charging the green batteries in your external charger, and
see how long they run. If it is significantly longer than when you charge
them in the JBR unit, you might be having some charging problems. OTOH,
if you see about the same (low) run-timne, then the batteries are probably
at fault. This is all assuming you are playing the same mix of songe
(same overall average bitrate) for each run.
