Microsoft has begun rolling out a new Windows 10 Mobile update for the Lumia 950 and Lumia 950 XL. The release brings a long list of fixes and improvements, and it’s the last one you’ll be able to download and install without being tethered to a charger.

This update comes with build number 10.0.10586.107, and it has already been tested by Windows Insiders. It is thought to be rolling out to those with unlocked devices first, but providing all goes well, it will then be made available to all Lumia 950 and 950 XL users.

Here is the list of changes:

  • Reliability and stability improvements.
  • Bluetooth connectivity improvements with car and other accessories.
  • Microsoft Edge improvements to PDF rendering and navigation.
  • Improvements for battery usage with Iris Recognition for Windows Hello.
  • Update system improvements to fix a situation where some users had phone software updates and app downloads stuck at 0% for extended time periods.
  • Change to update system to now require phone to be plugged into a charger when downloading and preparing phone software updates.
  • Fix for a problem causing erroneous low storage prompts for some users when trying to download phone software updates.
  • Fix for a problem that caused erroneous prompts of Outlook account settings being out-of-date for some users, although account settings had not been changed.
  • Fix for a problem that caused some phones to get stuck on BitLocker Recovery screen after a reset.

You’ll be able to download this update over-the-air and install it on your device as long as you have more than 50% battery life remaining. But as you’ll see in the change log above, future Windows 10 Mobile updates will require you to connect to the charger for some reason.

If you want to provide Microsoft with feedback for this update, you can do so using the Windows Feedback app on your Lumia device.
