The worst kept secret of 2025 is official. At its Awe Dropping event on Tuesday, Apple announced the iPhone Air, its thinnest iPhone to date. Just how thin is the iPhone Air? At its thinnest point, the new model is 5.6mm thick. To put those measurements in perspective, the iPhone 16 Pro is 8.25mm thick, making the Air nearly 2mm thinner than Apple's 2024 flagship. Prior to today, the 6.9mm thick iPhone 6 was the company's thinnest smartphone to date. Since then, newer iPhones have been thicker to accommodate larger batteries, Face ID, multi-camera arrays and other components. The iPhone Air reverses that trend. At the same time, Apple claims the Air is its most durable phone yet, with a frame made from recycled titanium. Additionally, the Air is encased in the company's Ceramic Shield material, which Apple says is now 3x more scratch resistant than previous iterations. As for the display, it's a 6.5-inch screen with ProMotion support up to 120Hz, and always-on functionality. Apple Internally, the iPhone Air features Apple's new A19 Pro chipset. Tim Millet, vice president of platform architecture at Apple, said the new chip, with its six-core CPU, is the fastest smartphone processor on the market.
