Which iPhones support iOS 27 and Siri AI? Apple's complex compatibility list explained

Apple has released iOS 27, offering an impressively broad compatibility list that includes 33 iPhone models, ranging from the iPhone SE (2020) to the latest iPhone 18 series. While the software update itself is widely accessible, the rollout of Apple Intelligence and the new Siri AI features is more restrictive. These advanced AI capabilities are limited to the iPhone 15 Pro and newer models. Furthermore, specific high-end features like expressive voices and advanced dictation require the latest hardware, such as the iPhone 17 Pro and newer, alongside specific memory requirements for iPads and Macs. Notably, Siri AI remains unavailable on iPhones and iPads within the European Union and China due to regulatory challenges, though it is accessible on macOS and visionOS. This complex tiered system highlights Apple's strategy of balancing broad software support with the hardware-intensive demands of its latest artificial intelligence integrations.
