en.Wedoany.com Reported - Apple iOS 27 does not drop support for any iPhone models; any iPhone running iOS 26 can upgrade to iOS 27, including the seven-year-old iPhone 11.

The two main goals of Apple iOS 27 include improving operating system performance and integrating AI capabilities based on Apple Intelligence and Siri into various features. Although AI-related improvements have garnered the most attention, the cleanup and optimization of the operating system bring a direct benefit: no iPhone models have been dropped from support. It is currently unclear which specific change has extended the lifespan of the iPhone 11. Apple promises that app launch speeds will increase by up to 30% after running iOS 27, thanks to a new optimization of the CPU scheduler. However, this performance improvement does not change the range of models that support Apple Intelligence and the new Siri AI features; the oldest models supporting these AI features remain the iPhone 15 Pro and Pro Max.

This version compatibility decision is notable not only because the iPhone 11, as an older model, still receives support, but also because not all Apple devices are treated equally. For example, watchOS 27 is only compatible with Apple Watch Series 10 and later, Apple Watch Ultra 2 and later, and Apple Watch SE 3, meaning three Apple Watch Series models, one Apple Watch SE model, and one Apple Watch Ultra model are excluded from the compatibility list, even though these devices could originally run watchOS 26.
