Predicting the exact list for iOS 19, expected in September 2025, involves considering Apple's past support trends. Typically, Apple provides updates for its iPhones for around five to seven years.

Based on recent reports and patterns, here is a likely list of iPhones that will be compatible with iOS 19:

iPhone 11

iPhone 11 Pro

iPhone 11 Pro Max

iPhone SE (2nd generation)

iPhone 17 series (expected to launch with iOS 19)

Based on current information, it is widely speculated that Apple will discontinue support for the iPhone XR, iPhone XS, and iPhone XS Max with the release of iOS 19. These models, all powered by the A12 Bionic chip and launched in 2018, would have received approximately seven years of software updates, which aligns with Apple's typical support window.

As with iOS 18, it is anticipated that while older supported devices will receive the core iOS 19 update, advanced features, especially those related to Artificial Intelligence and requiring significant processing power, may be exclusive to newer iPhone models equipped with the latest A-series chips (likely A17 Pro and later).

This information is based on the most recent reports and expectations. The official list of supported devices for iOS 19 will be announced by Apple at its Worldwide Developers Conference (WWDC) in June 2025, with the public release following in September 2025
