“One of the key specs you mustn’t ignore before purchasing an MP3 player is its battery life. This number gives you an estimate of how long your gadget will play tunes on a single charge–in the best-case scenario.

“In the real world, there are plenty of factors that will help drain your battery much quicker than you’d like. Those who belong to subscription services have it worse. Music rented from some services arrive in the WMA DRM 10 format, and it takes extra processing power to ensure that the licenses making the tracks work are still valid and match up to the device itself. Heavy DRM not only slows down an MP3 player but also sucks the very life out of them.”
