Apple Intelligence features in iOS 18 like Writing Tools, Genmoji, Image Playground, and notification summaries may have spurred the uptick in adoption between iOS 17 and iOS 18.

Apple views software updates as an integral part of the iPhone usage experience. Apple is able to deliver new functionality to older iPhones on a regular basis, plus the frequent updates that Apple rolls out address bugs and ensure the best protection from security vulnerabilities.

Apple says that providing iPhone users with new features over multiple years is something that is unique to the iPhone because of the deep integration between hardware and software. Apple views software updates as a way to provide value to customers over a long period of time, enabling them to hold onto their devices for years while still getting new experiences.

The newest version of iOS is set to debut next week at the Worldwide Developers Conference. We'll get a look at iOS 18's successor, which rumors say will bring some major design changes and exciting new features.
