Apple iPhone 17 Pro vs Apple iPhone 18 Pro
Smartphones comparison: specs, VersusAnything Score, key differences and a clear recommendation.
Apple's 2026 Pro brings the 2 nm A20 Pro chip, a variable-aperture main camera, a smaller Dynamic Island and up to 2 TB of storage, at a $100 higher starting price. The iPhone 17 Pro keeps the same screen size, the same 12 GB of RAM and a camera system that is still excellent, and is now discounted.
Quick verdict
Upgrade to the iPhone 18 Pro if you shoot in the kind of mixed light where a variable aperture matters, or you keep phones for four-plus years and want the newest chip. Buy the iPhone 17 Pro if you want nearly the same experience for less.
