In about 30 minutes I went from nearly fully charged down to about 1/2 of a charge. Due to this (and that it was a very basic audio player), it was the only time I used it as an audio player.

Something that I think might have alleviated the problem was to have a small LCD screen (like on a digital watch) to display items that change (such as the playing time) while using the e-ink display for items that don't change that often (album art, artist, album title, song title, track length). A small LCD display probably wouldn't consume much power (considering that a small battery can power a digital watch for years) and could also be handy for e-book uses (such as displaying the current page number).
