battery saving

I guess it depends on the storage type then because my runtime results with FLAC on the flash-based Sansa e200 were far superior to those of people who used MP3 & OGG.

I recently compared runtime with FLAC and MP3 on my ipod Color (60GB hard disk), and FLAC gave slightly longer runtime (about 7.5 hours compared to just under 7 hours IIRC).

All these speculations bring me back to the question: What player are we talking about exactly, Flopper?
First, on many players you'll get longer runtimes with Rockbox than with the original firmware - not on the players with portalplayer processor though (Ipods, Sansas, H10s and the M:Robe100). Second, if it's a hard disk player, the savings from using FLAC might not be very high but on flash based players it will (as has been pointed out).
And another question to Flopper: what build are you running? (I'm asking for the exact revision number) - the reason I ask is because there was a change in the Rockbox code about maybe a month ago (?) which should help getting more runtime out of your battery on most portalplayer based targets, maybe still not the same as the original firmware(s) but getting close...

Are you sure? Rockbox is updated several times per day. Check the Rockbox Info screen from the System menu to see what build you have.
