DRM is a battery vampire

Fangs for the memory

DRM protection software acts like a software vampire on your battery life. According to tests conducted by CNet, heavy DRM based systems slow down an MP3 player and "suck the very life out of them".

The blokes in the lab took a Creative Zen Vision:M, with a rated battery life of up to 14 hours for audio and 4 hours for video and tested it for 16 hours, with MP3s.

However, when they tried the same test with DRM based music files the machine could only manage 12 hours. The same applied for other players.

The iPod, playing back only FairPlay AAC tracks, underperformed MP3s by about eight per cent.

Most people will tell you that DRM sucks, but this is the first time that using files loaded it removes about a third of your battery life. µ
