iPhone 18 Pro vs. Foldable Ultra... What’s the Biggest Difference?

Apple may split its premium iPhone lineup between the iPhone 18 Pro series and a first foldable model, the iPhone Ultra.

The iPhone 18 Pro is expected to keep the familiar bar-style design and vapor chamber cooling.

The iPhone Ultra may use a foldable, titanium-based design, but could drop the telephoto camera and vapor chamber.

Both models are rumored to use the A20 Pro chip, with thermal design likely becoming a key performance differentiator.
