While we don't yet know the new iPhones Apple will be dropping this fall — though there are iPhone 17 rumors — we do know, per Apple's site, that the phones listed below will be compatible with iOS 26. Basically, if you have an iPhone that was announced in 2019 or later, you're in the clear:

Apple gave Visual Intelligence big updates in iOS 26, making the AI tool behave more like Google’s Circle to Search.

Apple wrapped up WWDC 25 earlier this week, and the very first developer beta of iOS 26 is now here. This early release gives developers (and the most impatient enthusiasts) their first hands-on encounter with features the company previewed on stage at Apple Park: a major redesign and AI upgrades for the iPhone software.

Apple is releasing a substantial new iOS iteration later this year, but like always, some iPhones will be unable to run the operating system and will be functionally left behind by the Apple ecosystem.

The iPhone 17 is pretty much a lock for the fall, but what about the AirPods and AirTag? Apple might have spilled the beans with a line of code inside its new mobile OS.

OS 26 is official and there's a lot to be excited about. With its unveiling on Monday at Apple's Worldwide Developer Conference, a new developer beta is available to install for, well, developers, but also anyone else willing to take the plunge into potential unstable territory.

Apple is making it easier for iPhone owners to add their own custom ringtones, but the change in iOS 26 is only a slight improvement versus iOS 18.
