Apple's iPhone 18 Pro, arriving three years after the iPhone 15 Pro, introduces a new A20 Pro chip, variable-aperture camera, smaller Dynamic Island, and significantly improved battery life, with prices starting at $1,199 for 256GB. The upgrade accumulates changes from three generations including larger displays, Camera Control, enhanced cameras, aluminum design, and vapor chamber cooling. For iPhone 15 Pro owners, the camera improvements, battery longevity, and faster charging make it a worthwhile upgrade, particularly for photography and video work.
