Performance and software

The phone ships with iOS 27. Storage options are 256GB, 512GB, 1TB and 2TB, and there is no memory card slot. If you shoot a lot of 4K or ProRes video, pick 1TB or more.

Cameras

The camera system matches the iPhone 18 Pro. The 48MP Fusion Main camera has a variable aperture from f/1.48 to f/4.0. You also get a 48MP ultrawide and a 48MP telephoto with 4x optical zoom. Apple quotes up to 8x optical-quality zoom. Video recording goes up to 4K Dolby Vision at 120fps. ProRes RAW and Apple Log 2 are there for professional editing. On the front, the 18MP Center Stage camera records 4K at 60fps.

Battery and charging

Battery life is the main reason to choose the Pro Max. Apple quotes up to 30 hours of typical use and up to 45 hours of video playback. That is six hours more typical use than the iPhone 18 Pro.
