Apple Releases watchOS 9.1 With Battery Life Improvements and Matter Integration

Apple today released watchOS 9.1, the first major update to the watchOS 9 operating system that came out in September. watchOS 9.1 has gone through several rounds of beta testing, and it accompanies the macOS Ventura launch, and the debut of iOS 16.1 and iPadOS 16.1.

watchOS 9 Feature
watchOS 9.1 can be downloaded for free through the Apple Watch app on the iPhone by opening it up and going to General > Software Update. To install the new software, the Apple Watch needs to have at least 50 percent battery, it needs to be placed on a charger, and it needs to be in range of the ‌‌‌‌‌iPhone‌‌‌‌‌.

Today's update introduces an extended battery life option when using Outdoor Walking, Running, and Hiking Workouts. You can opt to reduce the frequency of heart rate and GPS readings if you have an Apple Watch Ultra, a second-generation Apple Watch SE, or an Apple Watch Series 8.

Music can now download on the Apple Watch using WiFi or Cellular when it is off the charger, and the update adds support for the Matter smart home connectivity standard. Apple's full release notes for the update are below:

This update includes improvements for your Apple Watch.

That is seriously ridiculous. Series 7 watches are basically the same hardware, but Apple won't let them save battery life by taking less frequent heart rate readings? Shameful...

I cannot believe they are keeping the battery saving updates from my Series 7 watch I just bought months ago. This is one of the most ridiculous things I’ve seen this company do in a long time. There is no excuse for this.

Can’t wait to see how much battery life has been improved. The battery life on Apple Watch Ultra is already amazing as is. ??

It finally completed and I got another stand hour in. I still stand by what I said earlier, but if I were to give one suggestion on how to update the watch (other than having rest days or banking move calories for other days or specifically opting out of the monthly challenges) it's make software updates easier and allow us to wear the watch while the update process is happening.
