Why your iPhone may not get iOS 27, Apple’s next major update coming this week

iOS 27 arrives Sept. 14 with major Siri, AI, appearance and security upgrades — downloads will likely require Wi‑Fi.
Most iPhones from iPhone 11 onward are supported, but Apple Intelligence (the new AI features) is limited to iPhone 16/17 and iPhone 15 Pro/Pro Max.
Free up several GB of space and keep your phone plugged in for the update — battery life may temporarily dip while the device finishes background setup.
