Apple releases iOS 27 to the public on Monday, Sept. 14, following months of developer and public beta testing. Sources say it becomes available for compatible iPhones via the Settings app under General → Software Update, with Apple also rolling out updates for other platforms on the same day.

The standout change is a major upgrade to Siri, described as “Siri AI,” which adds more conversational and cross-app capabilities and is linked to Apple Intelligence. Multiple outlets report that Siri AI is limited by device model, with the most advanced Apple Intelligence features requiring iPhone 15 Pro or newer, while older supported iPhones can still use standard iOS 27 improvements. Apple also initially limits Siri AI by language (English) and imposes daily usage limits; access is described as not being available in the EU at launch.

Beyond Siri, outlets highlight refinements to Apple’s “Liquid Glass” interface, performance improvements (such as faster app launches, photo loading, and AirDrop), and features including iPhone Handoff (carrier-supported), Apple Cash bill splitting in the U.S., and added location controls in Find My. Some coverage also notes additional OS updates and broader release timing expectations, while the detailed feature lists vary slightly by outlet.
