Summary
- The iPhone Ultra is expected to measure just 4.5mm thick when unfolded, making it thinner than any iPhone ever released.
- It will feature a 7.8-inch internal display with a nearly invisible crease thanks to an advanced hinge mechanism.
- Under the hood, it is expected to pack Apple’s 2nm A20 Pro chip, 12GB of LPDDR5 RAM, and the C2 modem.
- Two color options are reportedly planned at launch: White and Black.
- The device is expected to debut alongside the iPhone 18 Pro series with a price tag exceeding $2,000.
Design: Thin, Wide, and Different
Let’s talk about the design. Prosser’s video shows the device in two finishes — White and Black — which are rumored to be the only launch colors. Not exactly a broad selection, but Apple rarely starts with a full palette.
4.5mm: A Record-Breaking Thickness
The headline feature is undoubtedly the thickness. At just 4.5mm when unfolded, the iPhone Ultra would be thinner than even the iPhone Air, which measures 5.6mm.
The rear camera system features two 48MP sensors housed within an iPhone Air-inspired camera plateau. There is reportedly no telephoto lens, unlike Apple’s Pro models. Some users may find that disappointing, but it is a reasonable trade-off for such a slim device.

Hardware: Serious Performance With A20 Pro, C2 Modem, and 12GB RAM
There are no surprises here — and that is a good thing. The iPhone Ultra is expected to share much of its hardware platform with the iPhone 18 Pro lineup, including the 2nm A20 Pro processor built on TSMC’s N2 process, 12GB of LPDDR5 RAM, and Apple’s new in-house C2 modem, replacing Qualcomm solutions.
The result should be improved power efficiency, stronger Apple Intelligence capabilities, and greater independence from Qualcomm.
The device is expected to launch alongside the iPhone 18 Pro series this September, with pricing starting above $2,000.
Our Take at Gizchina
A 4.5mm chassis and a nearly invisible crease sound impressive—if the rumors prove accurate. The expected $2,000-plus price tag, however, sets very high expectations.
The real test will come in September, assuming Apple delivers on what the leaks are promising.
