Can my devices run Apple’s latest updates?

The system requirements for iOS 16 are tightened up: iOS 16 is available for iPhone 8 and later and the second-generation iPhone SE and newer. The update requires Apple’s A11 Bionic chip or later, which excludes older devices like iPhone 6s or the first iPhone SE, released in 2016, which support iOS 15, iOS 14 and iOS 13.

No iPod touch models are supported by iOS 16.

The device compatibility list for watchOS 9 has some changes, too. Compared to its predecessor, watchOS 9 cuts off support for Series 3 and older watches. In other words, you’ll need at least Apple Watch Series 4 or later to run watchOS 9.

tvOS 16 supports both Apple TV HD and Apple TV 4K, just like tvOS 15 and earlier tvOS releases. If your Apple TV already runs tvOS 15, you can update it to the new tvOS 16 software. Read: iOS 16 settings to change to boost your iPhone experience
