The iPhone 18 Pro is Apple's 6.3-inch flagship for 2026, announced on 9 September and on sale in the UK from 18 September 2026 at £1,199 for 256GB. It is the first year Apple has launched only its Pro phones in September: the foldable iPhone Duo follows on 23 October, and the standard iPhone 18 is not expected until spring 2027. The change that matters is the camera. The 48MP main lens has a mechanical variable aperture with four stops from f/1.48 to f/4.0, so it can genuinely gather more light or hold a whole scene in focus rather than simulating either in software, and Apple exposes it through Pro controls for aperture and shutter speed. Underneath is the A20 Pro, Apple's first 2-nanometre chip, whose gains show up as battery life: Apple rates the Pro at up to 34 hours of video playback, with a 50% charge in around 15 minutes from a 60W adapter. The Dynamic Island is smaller, Face ID stays, the aluminium unibody is unchanged at 8.75mm, and storage now runs to 2TB. Colours are black, silver, glacier and burgundy.
