On September 10, 2025, at its autumn new - product launch event, Apple unveiled four iPhone models: the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air. All these models are outfitted with Apple's in - house developed N1 chip. This innovative chip boasts support for Wi - Fi 7, Bluetooth 6.0, and Thread connectivity technologies, marking a significant and all - around upgrade of local wireless capabilities.

The N1 chip is seamlessly integrated with the A19/A19 Pro processors and the iOS 26 system. This integration allows for intelligent resource allocation tailored to different usage scenarios. As a result, it enhances operational efficiency and cuts down on power consumption. When compared to the Broadcom chip used in the iPhone 16 series, the N1 chip delivers a 30% improvement in overall efficiency. This is particularly noteworthy in the ultra - slim iPhone 17 Air. Despite its slender 5.6mm profile, the device can still maintain all - day battery life.

The N1 chip fully leverages the capabilities of Wi - Fi 7. It offers a more than 20% increase in actual data transfer speeds, ultra - low latency of under 20ms, and an expanded coverage area along with enhanced security features. In terms of Bluetooth 6.0, engineering optimizations have been made, such as interference suppression and multi - stream audio support. These improvements extend the connection range of AirPods by 50% and reduce power consumption by 15%.
