The iPhone 18 Pro and Pro Max could adopt three design changes, including a revised rear finish, a smaller dynamic island and new colour options, a report said. The two-tone back used on the iPhone 17 Pro may be replaced by a unified colour for the rear glass and aluminium. The dynamic island could shrink by about 35 percent, partly due to moving some Face ID components under the display.

The iPhone 18 Pro series may become thicker and heavier than the previous model, with speculation also rising that a black-toned option could be excluded. Reports offer conflicting estimates on thickness, ranging from about 9 mm to about 10.75 mm depending on whether the body or camera bump changes. Leaked figures also suggest the iPhone 18 Pro Max could weigh about 240 grams. Color expectations have narrowed to three options in some forecasts.
