Apple's iPhone 18 Pro, arriving two years after the iPhone 16 Pro, features over 50 upgrades including a new A20 Pro chip, variable-aperture camera, smaller Dynamic Island, and record battery life of 36 hours. The $1,199 starting price is $200 higher than the iPhone 16 Pro's launch, though base storage doubled to 256GB. For iPhone 16 Pro owners, the cumulative changes across two generations—including design, display, cameras, and charging speed improvements—make it a worthwhile upgrade.
