Apple Launches iPhone 18 Pro with Variable Aperture Camera

Apple released the iPhone 18 Pro and iPhone 18 Pro Max featuring the A20 Pro chip built on a 2nm process. The new chipset includes a seven-core GPU that is 40% faster than the A19 Pro and a dual 16-core Neural Engine to power enhanced Siri AI capabilities in iOS 27. The devices start at $1,199 and $1,299, reflecting a $100 price increase attributed to component shortages.

A primary hardware addition is a 48MP main camera with a six-blade mechanical variable aperture system driven by electromagnets, allowing for manual controls over aperture, shutter speed, and white balance. To manage heat, Apple implemented a vapor chamber cooling system with three times the surface area of previous versions, placing the processor directly against the cooling system. The Pro Max model is heavier at 249 grams due to a larger battery and this expanded thermal system.

Hardware teardowns revealed a divergence in cellular connectivity: the iPhone 18 Pro uses Apple's in-house C2 5G modem, while the Pro Max utilizes the Qualcomm Snapdragon X80. The Dynamic Island cutout is now narrower because the infrared camera was moved into the corner of the display. REWA Technology and other analysts noted that the new camera assembly is essentially unfixable at the component level, requiring a full assembly replacement if the aperture fails. While the devices received a provisional repairability score of 7 out of 10, some technicians reported that plastic display frames cracked during removal.
