A new BIOS update is now available (opens in new tab) for the Dell XPS 13 (9360) that should bring greater battery life, among other changes. According to Dell, you should see up to 14% better battery life in local and streaming video playback as a result of offloading the audio processing from the CPU to the digital signal processor.

Here's a full look at the changes in the XPS 13 9360 1.2.3 BIOS update:

  • Fixed System may hand at DELL logo while resume from System hibernation
  • Fixed Dell Thunderbolt Dock may lost during Cold Boot \ Cold Boot
  • Add support for Audio Digital Signal Processing (DSP)
  • Fixed system may not able to boot ( Need to Press power button few times ) after dirty shutdown
  • Fixed no "safe remove" on taskbar when plug-in USB key to right USB port

Once installed, you should start seeing improved battery life while streaming from Netflix or through the Movies & TV app. If you'd like to check it out, you can grab the 1.2.3 BIOS update for the XPS 13 (9360) from Dell now. Though it's not required, Dell also recommends grabbing the latest audio driver (opens in new tab) as well.

  • This BIOS update also breaks NVMe boot devices (at least Samsung ones) in windows and all NVMe in Linux. See http://en.community.dell.com/support-forums/software-os/f/4997/t/20000243 and http://en.community.dell.com/support-forums/laptop/f/3518/t/20000065 very frustrating.
  • GTK, thanks
  • DellBIOS.txt Botched BIOS updates are why I parted with my 9550. It's a circus at Dell. Every update fixes a few things and breaks some things. Now it will be a 3 month wait for them to fix the NVMe issue. Fun! Just can't be trusted as a main machine, IMO.
  • I went through a year of wifi issue back when the venue tablet was released, after I threw in the towel I moved to the Surface Pro line. Microsoft had the same issue and resolved it in 1 month. Dell had this one support guy working the forums the entire year... Yes 1 guy..
  • I just recently got an XPS 13 9360 and finally managed to get my 960 EVO to be detected by the BIOS. I haven't updated the BIOS yet, so does this mean I should be fine now as long as I never update it?
  • Nice
  • Dell has confirmed the BIOS boot issue in 1.2.3. A fix is coming.http://en.community.dell.com/support-forums/laptop/f/3518/p/20000065/209...​
