Apple’s compatibility roster for iOS 27 stretches as far back as the iPhone 11 and the second-generation iPhone SE. A handset that’s five years old, plus a budget model that shipped with a home button, are both still in line for Apple’s newest software.
Release timing: today, September 14th, at 20:00 Greece time.
Buyers of the iPhone 18 Pro, iPhone 18 Pro Max or iPhone Duo have nothing to do — iOS 27 ships pre-installed on those handsets. Everybody else is queuing for the download.
What Apple says you’re getting
Apple’s pitch covers improved performance, new features, an enhanced Liquid Glass with more user options, Siri AI and other key functionalities. Those are Apple’s words rather than mine, and “improved performance” is the sort of claim that only becomes meaningful after the update has lived on your phone for a week and you can judge whether the battery survived.
The detail worth tracking is Liquid Glass gaining more user options. That design push divided opinion sharply last time around, and Apple’s answer is to hand over more control instead of backing away from it.
The full compatibility list
The entire iPhone 16 and iPhone 17 range is fully supported, along with the remainder of the lineup stretching back four generations.
The complete rundown: iPhone Duo, iPhone 18 Pro Max, iPhone 18 Pro, iPhone 17 Pro Max, iPhone 17 Pro, iPhone Air, iPhone 17, iPhone 17e, iPhone 16 Pro Max, iPhone 16 Pro, iPhone 16 Plus, iPhone 16, iPhone 16e, iPhone 15 Pro Max, iPhone 15 Pro, iPhone 15 Plus, iPhone 15, iPhone 14 Pro Max, iPhone 14 Pro, iPhone 14 Plus, iPhone 14, iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13, iPhone 13 mini, iPhone 12 Pro Max, iPhone 12 Pro, iPhone 12, iPhone 12 mini, iPhone 11 Pro Max, iPhone 11 Pro, iPhone 11 and the iPhone SE from the second generation onward.
Supported isn’t the same as good
Making the list only guarantees that installation is possible. It carries no promise that every feature will appear.
The small print tends to hide inside that gap, and it’s worth reading before you hit install on ageing hardware. An iPhone 11-era device running a 2026 release is straining to keep pace.
What to do tonight
If your handset qualifies and you depend on it for anything that can’t afford to break, hold off for a few days. Launch-day builds are where the strange bugs turn up, and nobody hands out medals for updating first.
iPhone 16 and iPhone 17 owners sit in the bracket Apple specifically flagged as fully supported, which is about as safe as this situation gets.
And for anyone still on an iPhone 11 or a second-generation SE, treat the update for what it really is: the final stretch of a lengthy support run, on hardware that has earned it.
