Apple is releasing its latest watchOS 6.1 update today, and it will introduce watchOS 6 support for the Series 1 and 2 Apple Watch models. watchOS 6 originally debuted last month, but Series 1 and 2 owners have had to wait on this 6.1 update to upgrade.
This latest update also includes support for Apple’s new AirPods Pro headphones, just a day before they start shipping to customers. Aside from these changes, it’s a fairly minor update for Apple Watch owners that were already running watchOS 6, but it includes the usual performance improvements and bug fixes that you’d expect from a point release.
Apple hasn’t revealed whether this update improves battery life on the latest Series 5 Apple Watch. Some owners have reported issues with the battery life not lasting a full day, and beta copies of watchOS 6.1 appeared to improve things for some. Either way, watchOS 6.1 is available right now from the General > Software Update section of the Watch app on iOS.
