Sansa Fuze Battery Life
SanDisk is pretty proud of the 24-hour per charge lifetime featured in the Sansa Fuze battery - but how do you really get 24 hours of playing time out of any device? Let’s break it down.
Music: You can enjoy plenty of music playback, as long as your songs play at 128 kilobits per second. This is a fairly low quality compression, which means you’ll be turning up the volume and potentially damaging your ears. If you listen to music with higher quality compression, such as 256 kilobits per second, you can be certain you won’t see 24 hours of music playback.
Video: SanDisk says you can get five hours of video playback time if you watch MP4 videos with playback rates of 512 kilobits per second and still get 24 hours of music. This isn’t too shabby, especially considering that you’ll be watching on a teensy screen.
However, don’t expect to mix and match your video and music for long. Watch one video, then listen to a few hours of music, and you’ll probably be ready for a recharge. Otherwise, depending on the gigabyte capacity of your model, you’re looking at anywhere between 6 and 24 hours of total video playback time.
Photo: Photo playback is more variable than music or video. The Sansa Fuze is capable of displaying 6 megapixel photos, which is fairly decent for its size, but there’s no concrete time limit for how long the battery will last. The moral of the story: You’re not going to be looking through photos for 24 hours solid anyway, so just glance at your leisure and try not to focus on the Sansa Fuze battery life at the same time.
