iPhone 18 Pro vs iPhone Ultra: Three features to win your upgrade

Apple’s rumored iPhone 18 Pro lineup may split into a conventional Pro model and the first foldable iPhone Ultra.

The biggest differences could be form factor, with the Ultra using a foldable design instead of a traditional slab phone.

Camera hardware may also diverge, as the Ultra is said to lack a telephoto lens that remains on the Pro.

Performance could vary too, depending on materials and cooling hardware such as a vapor chamber and aluminum unibody.
