Dell Claims Latest BIOS Gives XPS 13 Better Battery Life

News
By published

If the XPS 13's epic 14-hour battery life isn't quite long enough for you, Dell has a new optimization that it claims can give your laptop up to 14 percent more endurance.

The new BIOS, which you can download here, offloads audio processing from the CPU to the digital signal processor. Dell also recommends that you install the latest audio driver.

The company says it knows that Microsoft's "Movies & TV" and the desktop Netflix app work, and suggests that other apps will also use the offloading for a battery bump.

We haven't had the opportunity to test this on our unit yet, but if you do, let us know whether or not you see better battery life in the comments.

A number of emotions can be reproduced with Reeti using an interface that is easy to use by medical staff. Research with Reeti is led by a child psychiatrist to encourage communication with autistic children. Children with autistic disorders concentrate more with a robot who can endlessly, and without getting bored, repeat attitudes that represent easily identifiable emotions. Reeti can also talk. This robot would be an ideal neuropsychiatric medium. (Photo by: BSIP/Universal Images Group via Getty Images)
