iOS 27 is here: a guide to what's new on your iPhone

Apple's new iPhone software, iOS 27, is now available, and it runs on the newly released iPhone Duo. The biggest change is a revamped Siri, but it only comes to iPhones that support Apple Intelligence, Apple's set of built-in AI features.

What changed

CNET's cheat sheet says iOS 27 brings a handful of features to all compatible iPhones. One example is an updated Safari, Apple's web browser. The new Siri is different. It arrives only on devices that work with Apple Intelligence.

Many of the other upgrades are subtle, under-the-hood changes. That makes them easy to miss, even on a brand new phone or one you just updated.

Who it affects

Anyone with an iPhone that can run iOS 27 is touched by this update. What you get depends on your model. Safari changes reach all compatible iPhones. The new Siri reaches only those that support Apple Intelligence.

What to do

• Check whether your iPhone is compatible with iOS 27 before you update.
• Check whether it supports Apple Intelligence if you want the new Siri.
• Look around your phone after updating, since some changes are small and quiet.

What happens next

iOS 27.2 is the next version. CNET reports it is wrapping up beta testing, which is the stage where early versions are tried out before a public release, and it is expected to launch soon. The source material does not give a release date for it, and it does not list which iPhone models support Apple Intelligence or the new Siri.
