Apple says iOS 27 will be available as a free software update on Monday, 14 September 2026, for compatible iPhones. The date sits in the footnotes of Apple’s iPhone 18 Pro Newsroom release from 9 September, and MacRumors and 9to5Mac both put the same Monday on the public rollout.
Which iPhones get it
iOS 27 keeps the same handset cut-off as iOS 26. That means iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max, plus every later model, including the second-generation iPhone SE and newer. Owners of an iPhone XS, XR or older stay on their current major release.
Newer headline tools such as Siri AI still need newer silicon. Reporting tied to Apple’s notes points to iPhone 15 Pro and later for the heaviest Apple Intelligence features, even when the base update installs on older supported phones.
How to install on the day
Once Apple pushes the build, open Settings, tap General, then Software Update. Leave the phone on Wi-Fi, plugged in if the download is large, and accept the usual backup prompt before installing. The update is free through Apple’s own channel. No App Store purchase is required.
What else lands the same Monday
Apple’s June OS briefing covered iPadOS 27, watchOS 27 and macOS 27 alongside iOS 27. Those companion platforms are also due on 14 September. For iPhone users in Singapore, the practical move that day is still the free iOS 27 Software Update.
The free Software Update lands on Monday, 14 September 2026.
