iOS 26 Is Out With Support Starting at iPhone 11 and Practical Update Requirements

Apple’s official list excludes the XS, XR and iPhone 8 era while keeping the SE (2nd generation and later) eligible.

Overview

Apple confirms iOS 26 runs on iPhone 11 through iPhone 17 families and on iPhone SE models from the 2nd generation onward.
Older devices such as the iPhone XS, XR and iPhone 8 no longer qualify for the new OS.
Installing iOS 26 typically requires roughly 6–7 GB of free storage, a stable Wi‑Fi connection, at least 50% battery or power, and Apple ID/passcode verification.
Some Apple Intelligence features remain limited to newer, higher‑end iPhones, including recent Pro models listed in coverage.
One guide contains an internal contradiction by mentioning both that XS is unsupported and that XS or newer is required, but Apple’s stated cutoff begins with iPhone 11.
