Volume doesn’t matter much as far as battery life. Shuffle probably doesn’t use that much more power. What matters most is how often the display is on and how bright it is, that you use mp3 and not another format(the others use much more power except when using Rockbox). Also using the equilizer will greatly decrease battery life.
So playing WMA uses considerably more power than playing mp3?
Yes, with SanDisk’s firmware, FLAC, Ogg Vorbis, and WMA use more battery power to play than with MP3. Strangely enough, with Rockbox, those three give better battery life than MP3.
