On the other hand, the updates also add support for Bluetooth Low Energy audio. If you remember, this particular feature will let you use your wireless Bluetooth headphones much longer while providing the same audio quality.
The technology doesn’t take a lot of your devices’ battery, allowing for a sustainable way to enjoy your music, podcasts, and whatever you’re listening to.
Here’s the list of the other improvements coming to Windows 11 with this new update.
