DRM Shortens Battery Life by 25%

microsoft playsforsure logoI’m not a social scientist, but I think it’s funny how people who have a disdain for certain products, services, or people look for every conceivable way to discredit them (sometimes justly). Case in point: Tests reveal DRM shortens battery life by 25% in portable music players (via Digg, CD Freaks). The bottom line is that DRM-wrapped digital media takes up more CPU horsepower to playback because the player needs to decrypt files on the fly. Makes sense… and adds another reason to people’s list of why “DRM is evil.”

    No doubt that decryption requires more MIPS, the worst part is that WMA itself already requires more MIPS to decode. The more complex your compression/encryption is, the more instructions it will take to decode, the less battery life you get.
