Apple's upcoming iOS 27 could push more users toward new iPhone purchases than any recent software update. While the compatibility list might support iPhone 12 and newer, rumors suggest that AI-heavy features will be the real upgrade driver. This marks a shift from Apple's typical approach of supporting devices up to six years old.

iOS 27 appears poised to limit its best capabilities to Apple Intelligence-compatible hardware. That means only iPhone 15 Pro and newer models will access the upgraded Siri with large language model capabilities, chatbot interface, and contextual awareness. Users with iPhone 12 through iPhone 15 will essentially get a stripped-down experience.

The AI requirement extends to major new features including the redesigned Photos app, custom wallpaper generation, video subtitles, and natural language Shortcuts. These aren't minor additions—Apple seems to be building its next-generation software around artificial intelligence as a core selling point.

This strategy makes business sense for Apple but creates a clearer divide between capable and legacy devices. For users who've held onto older iPhones, iOS 27 may finally present enough compelling AI features to justify upgrading to a model that supports Apple Intelligence.
