No iPhone Ultra today? Three possible explanations …

It was widely expected that the first foldable iPhone would be named the iPhone Ultra, but reports suggest it will be called the iPhone Duo instead. This development could indicate Apple reserving the Ultra suffix for a different future model. The Ultra label has been used previously to signify top-level offerings, such as the iPhone Ultra and MacBook Ultra.

However, the foldable phone is expected to lack several features compared to the iPhone Pro models, including a variable aperture lens, telephoto camera, Face ID, and battery life. This has led to three possible explanations. The least likely is that Apple is avoiding the Ultra label due to the device's inferiority compared to the iPhone Pro models.

Despite this, Apple has not always followed this logic, as seen with the MacBook Air and Mac Studio naming. Another possibility is that the iPhone Ultra label is reserved for the 20th anniversary model, expected next year, which would bring the iPhone closer to the vision of a single slab of glass. The most exciting explanation is that Apple has more all-new iPhone additions planned after the launch of the iPhone Glass and that the Ultra label will be reserved for a different model, potentially one with superior camera capabilities.
