Apple's upcoming iOS 19 update, set to be unveiled at WWDC 2025, may not be available for certain older iPhone models, including iPhone XR, XS, and XS Max.
Apple typically continues to provide security updates for older devices even after they stop receiving major iOS updates.
iOS 19 is expected to be compatible with newer iPhone models such as iPhone 11, 12, 13, 14, 15, SE (2nd and 3rd generation).
Reports suggest that the 5th-generation iPad Mini will still be supported with iOS 19 update, but the 7th-generation iPad may not receive the update.
