Update watchOS 9 and use Low Power Mode on your Apple Watch

Apple has revealed what we’re sacrificing with the feature.

We finally know what will exactly happen when we turn on the low power mode on the “Far Out” special event.

As leaked by MacRumors, the company has created a new page on the Apple Support website called “Use Low Power Mode on your Apple Watch(opens in new tab).” The document, which coincides with the release of watchOS 9 earlier today, talks about how to turn on the feature and what it will do for your watch.

Although the low power mode is a great function to allow you to use your Apple watch for a longer time, it does come with a price–Twelve other features will be affected when you turn on the low power mode.

Some features will be turned off by Low Power Mode.

Apple says that the following features will be turned off completely when Low Power Mode is turned on:

  • Always On display
  • Heart rate notifications for irregular rhythm, high heart rate, and low heart rate
  • Background heart rate measurements
  • Background blood oxygen measurements
  • Start workout reminder

If your iPhone isn’t nearby your Apple Watch, the following features will also be turned off:

  • Wi-Fi and cellular connections
  • Incoming phone calls and notifications

Lower Power Mode, while not turning these things off completely, also has the following effects:

  • Making a phone call can take longer
  • Background app refresh happens less frequently
  • Complications update less frequently
  • Siri can take longer to process a request
  • Some animations and scrolling might appear less smooth

As you know, this mode turns off many core functions, especially when your iPhone isn’t around, so you’re unlikely to find it useful unless you desperately need to preserve battery life. It’s still a great feature, but keep in mind that by extending battery life, you’ll be shutting down a lot.

Lower Power Mode is available as part of watchOS 9 which was released today alongside iOS 16 and tvOS 16.

watchOS 9 is by far the most significant update to Apple Watch fitness-tracking features we’ve seen in years, finally making the Apple Watch the talk of the top fitness tracker.
