A private but reputable source on X — known for accurate iOS-related leaks — claims that iOS 26 will support only iPhone 11 and newer, along with the iPhone SE (2nd generation and later).
While the original source remains unidentified, their previous track record adds credibility. If accurate, this means iOS 18 would be the final major up date for the iPhone XS, XS Max, and XR, though these models will likely continue receiving security updates after iOS 26’s release.
iPhone 11, 11 Pro, 11 Pro Max
iPhone 12 series, including 12 mini and Pro models
iPhone 13 series, including 13 mini and Pro models
iPhone 14 series

iPhone 16, 16 Plus, 16 Pro, 16 Pro Max, 16e
iPhone SE (2nd gen and newer)
All upcoming iPhone 17 models
As with previous versions, some advanced features will be limited to newer hardware. For instance, Apple Intelligence features will reportedly require an iPhone 15 Pro or newer.
The same account successfully predicted iOS 18 compatibility last year, further boosting confidence in this latest report.
