The next major iPhone software version is iOS 27, launching very soon. Following months of beta testing, Apple always ships major iOS releases in September. Based on historical patterns—iOS 26 on September 15, iOS 18 on September 16, iOS 17 on September 18, and iOS 16 on September 12—iOS 27 is expected to launch on or around Monday, September 14.

The official date is typically revealed at Apple’s annual iPhone event, which usually occurs the week prior. Current expectations point to the iPhone 18 Pro unveiling on or near September 9. iOS 27 introduces new features in Wallet, Photos, Messages, Notes, CarPlay, and AirPods, alongside a major Siri AI overhaul. It will be compatible with all iPhone models supported by iOS 26.
