    So does higher mp3 bitrates take more battery power? If you have 320 bitrate instead of 128 or 64 kpbs??

    From my experience, no.

    I used to encode to 128 for my 256M player and got about 10 hrs (1 AA battery). I've done full capacity with 192, then with 320 and got about the same. The volume always stays the same, as well as continuous play (no skipping or jumping back and forth).

    Not really. Same for WMA vs MP3.

    Never heard of that but it sounds logical since it has to do more processing. On the other hand I'd imagine turning the volume up even the slightest bit would have more affect on the battery life.

    I read an article recently talking about how DRM protected audio files kill battery life more than non-DRM protected music, it didn't mention bitrates though.

    Extra CPU cycles required to process higher bitrates have a small impact on battery life. If you have a hard drive based player then higher bitrate = larger file size = more power consumed spinning the hard drive = a noticable decrease in battery life. This is not an issue with flash based players.

    DRM knocks battery life down by as much as 25%.

    The anti-DRM crowd ought to point that out to the tree hugger crowd.
