Vorbis - Feb 2008 - FYI: power consumption MP3 vs. Vorbis

Hi,

I'm using a Samsung YEPP 6 for some time, but I recently got surprised: It
seems
that listening to Ogg (=Vorbis) empties the batteries much faster than listening
to MP3. Both files have about the same bit rate. I did not make electrical 
measurements, but I think things are as they seem to be.

Did anybody make similar experience? Or maybe "required CPU cycles to
decode"
statistics? It would be great if Vorbis needed less power than MP3...

Regards,U
Ulrich

Unfortunately Vorbis is more intensive than mp3 (this is why old
hardware players couldn't handle it), sometimes leading to higher
battery drain.  (That said I use rechargeable batteries in my player
and rarely have to change them.)
