iOS 27 Released: Wider Support, but Advanced AI Requires Newer iPhones
Apple's iOS 27 update, released at WWDC 2026, offers broad compatibility across most iPhones dating back to the iPhone 11 series. However, its most powerful on-device AI features, part of the new Apple Intelligence suite, demand newer hardware, specifically the iPhone 17 Pro or iPhone Air models with 12GB of memory.
Key points
- iOS 27 is compatible with iPhone 11 series and newer.
- Most advanced on-device AI requires iPhone 17 Pro or iPhone Air.
- Newest on-device AI model needs 12GB of memory.
- Standard Apple Intelligence features will run on older supported devices.
Apple has officially announced iOS 27 at its WWDC 2026 event, bringing a suite of upgrades including enhanced Siri capabilities and new Apple Intelligence features. Notably, the company has maintained broad device support, confirming that most iPhone models from the iPhone 11 series onwards will be compatible with the upcoming operating system. This includes models like the iPhone 11, iPhone 12, iPhone 13, iPhone 14, iPhone 15, iPhone 16, and the entire iPhone 17 lineup.
However, the most sophisticated on-device AI functionalities within Apple Intelligence will be exclusive to a more limited set of hardware. Apple has stipulated that running these advanced AI models requires devices with at least 12GB of unified memory. Consequently, only the iPhone 17 Pro, iPhone Air, and certain iPads and Macs with M4 or later processors will be able to leverage these top-tier features. Standard Apple Intelligence features are expected to remain accessible on older, compatible iPhones, potentially utilizing cloud processing for more intensive tasks.
