Tests find DRM shortens player battery life by up to ~25%
`When users take the specifications of an MP3 player into consideration, one very important factor most take into account is the rated battery life. However, as many are aware, the battery life stated is generally the runtime from a full charge in ideal conditions, such as when the player is left playing without any sound enhancements (EQ, bass-boost, etc.), volume set to a moderate level, all music is 128kbps MP3, backlit display goes out within a few seconds and so on. However, according to tests conducted by CNET, they found that while many players met or exceeded their claims, one feature that has a drastic affect on battery life is the infamous DRM.’
