Alongside the A20 Pro chipset, Apple is also upgrading its modem, adding its own home-built C2 5G modem onboard, which supports NR-NTN (New Radio Non-Terrestrial Networks).
This technology will enable satellite connectivity. In contrast, Apple’s current flagship, the iPhone 17 Pro Max, uses the Qualcomm Snapdragon X80 cellular modem.

Although there won’t be a major upgrade to the camera hardware, the iPhone 18 Pro Max will get a 48MP main sensor with a variable aperture that shifts between f/1.6 and f/4.0, coupled with a 48MP periscopic telephoto camera sensor with an f/2.8 aperture lens, and another 48MP ultrawide-angle sensor with an f/2.2 aperture lens.
On the front, the 18 Pro Max will support the 18MP Center Stage camera.

According to leaks, the iPhone 18 Pro Max 5G will have a slightly smaller Dynamic Island. Apple has completely reengineered its design. The Face ID sensor will be placed behind the display and can scan through it, saving more space for the display. This will also increase the screen-to-body ratio.
The iPhone 18 Pro Max will feature a 6.9-inch LTPO Super Retina XDR OLED panel with a 120Hz refresh rate and Dolby Vision support. The iPhone 17 Pro Max already has the same 6.9-inch LTPO Super Retina XDR OLED display with a 120Hz refresh rate.
