Wouldn't the battery usage have more to do with the length and bitrate of the song, rather than the type? |
They're also factors; but my understanding is that MP3 and WMA files of the same length and bitrate differ in terms of battery power used.ÂÂ*ÂÂ*See the following excerpt from an article on dapreview.net on battery usage:
In fact, digital audio player manufacturers who list battery life for plain MP3’s and WMA’s routinely list WMA battery life at 4 hours below what they state for MP3 playback (for example, the Olympus m:robe MR100 states 12 hours of playback with MP3 and 8 with WMA), which is exactly the difference CNet’s test found between MP3 and WMA-DRM. For a comparison to actually be valid or useful, WMA’s of the same bitrate with and without DRM would need to be examined. So that’s what we did.
