DRM shortens player battery life by up to ~25% ?

I spotted this on Digg, I think some more testing needs to be completed with better control groups, files and players but even if there’s a tiny loss, that’s a huge waste of time and power – “Tests were done on portable music players using standard MP3 files and DRM encrypted WMA files. The results. Up to 25% less battery life thanks to DRM sucking the juices as it constantly verifies licenses.” – [via] Link.

Between Sony’s rootkit and a potential 25% loss of battery life, the music folks along with the hardware & software vendors and really accelerating a customer revolt.
