Apple has just released the new version of iOS, the company’s operating system for the iPhone. iOS 17 is a free download and it works with the iPhone X or later, as well as the second- and third-generation iPhone SE. Apple is also releasing major updates to watchOS, iPadOS and tvOS today.

I would say that the main change in iOS 17 is the new StandBy mode. When you’re not using your phone and you put it down on a wireless charger, your iPhone displays full-screen widgets for quick, glanceable information.
