Apple iPhone 17 Pro vs Apple iPhone 18 Pro

Our Verdict: Apple iPhone 18 Pro adds variable aperture control to the main camera and a 2TB storage option beyond the 1TB ceiling of Apple iPhone 17 Pro. Both use 6.3-inch OLED displays, and the newer phone is only slightly heavier at 211g against 206g. Those specific camera and storage additions matter most to demanding users; the older Pro retains a very similar screen format for everyday tasks.

Over a full contract, the 17 Pro works out around £1026 all-in, about £190 less than the 18 Pro.
