iOS 27 may run on devices as far back as the iPhone 11, but Apple's most advanced AI features are reserved for a much shorter list of hardware, the company revealed.Apple's Craig Federighi, Senior Vice President of Software Engineering, confirmed that a subset of advanced Siri AI and Apple Intelligence features will require more powerful silicon, and therefore won't be available on most iPhones. That means that even relatively new iPhones that do support Siri AI and Apple Intelligence, like the iPhone 16 Pro Max, won't get the full experience when iOS 27 launches this fall.
In a WWDC presentation (as reported by Macworld and other outlets), Federighi said, "Our most powerful on-device model and the features it enables, like expressive voices and more advanced dictation, will be coming to our most capable iPhone, iPad and Mac systems."
