iPhone 18 Pro Max: Display

The 6.9-inch LTPO Super Retina XDR OLED runs at 120Hz and matches the iPhone 17 Pro Max for size and resolution. It is rated at up to 1600 nits in high-brightness mode for outdoor use, with the peak figure reserved for HDR. The trade-off is size: at 6.9 inches this is a two-handed phone, and anyone wanting the same panel in a smaller body should consider the iPhone 18 Pro at 6.3 inches.

iPhone 18 Pro Max: Camera

The main change is a variable aperture on the 48-megapixel main camera, shifting between wide and narrow openings for depth-of-field control. It sits alongside a 48-megapixel 4x telephoto and a 48-megapixel ultrawide, with video up to 4K 120fps. The 4x telephoto is unchanged from the iPhone 17 Pro Max, so buyers wanting longer optical zoom gain nothing this generation.

iPhone 18 Pro Max: Battery

The Nano-SIM model carries a 5391 mAh battery, up from 4823 mAh on the iPhone 17 Pro Max, which posted an Active Use score of 17:58h in GSMArena testing. Apple rates a 50 percent charge in 15 minutes over PD3.2 wired, and the larger cell should build on that, though the phone has not yet been lab-tested. Wireless charging stays at 25W, so the gains are in capacity and wired speed.

iPhone 18 Pro Max: Size, Weight and Build

The phone measures 163.4 x 78 x 8.8mm with an aluminium frame, a Ceramic Shield 2 front and an IP68 rating, in Black, Silver, Glacier and Burgundy. At 249g it is 16g heavier than the iPhone 17 Pro Max despite identical dimensions, making it one of the heaviest phones in the current range.

iPhone 18 Pro Max: Performance

The A20 Pro runs on a 2nm process with a 7-core GPU and 12GB of RAM, on iOS 27. That is a full node step down from the 3nm A19 Pro in the iPhone 17 Pro Max, which typically improves efficiency and speed, and Apple's Pro line has a long record of multi-year iOS support. Everyday gains are unlikely to show for anyone on a recent Pro model, so the chip matters most for demanding work such as high-frame-rate video.

iPhone 18 Pro Max: Who Should Buy

The iPhone 18 Pro Max suits buyers who want the biggest screen and the most endurance Apple offers and are comfortable with a 249g handset. It is aimed at heavy users on an older iPhone who rely on the telephoto camera, not those cross-shopping the smaller iPhone 18 Pro for one-handed use. Buyers comparing on contract length or upfront cost will find current network pricing in the table above.
