With the release of watchOS 9, Apple has also updated iOS 16 for iPhones eight and higher.
Because watchOS9 is focused on fitness, users can now analyze their sleep patterns and observe their heart rate zones while exercising. Support for multisport workouts is another upgrade that lets users keep track of their top performance. There are also brand-new watch faces, Quick actions, a redesigned Siri interface, and a reminder for the user to take their daily prescriptions.
Your iPhone must first support iOS 16 and be upgraded before installing it. Open the Settings app, select General, Software, and then Update to complete the process.
Apple Watch devices listed below and an iPhone 8 or later running iOS 16 or later are required for watchOS 9.
