Also, regarding that link, how can 'NOT PLAYING LCD OFF (70)' draw more current than 'Playing mp3 128kbps lcd off' (46-55)???

Theres a bug that causes how power draw when the system is first turned on.  I'm pretty sure those measurements are skewed by it.

Huh. So when you need to not listen for a while I guess it's better for battery life to just pause the player rather than turn it off?

AlexP:
When the player is first booted it draws more current until audio is played.  Thereafter if music is stopped, current draw is normal.  It is therefore best to turn off the player when idle (of course).  The excess draw will only manifest if you turn on the gigabeat then don't play music.  As soon as you play anything, everything works as expected.

OK - thanks. Don't let it sit w/out playing music after turn-on - check.

Alternatively, set the player to resume on start-up (Settings > System > Start Screen > Resume Playback) and it will be automagically fixed  ;D

This also explains why playing Jewels appeared to chew so much battery for me; I was just booting and going straight to the plugins :(

The backlight also consumes quite a lot.
