Dummy units leaked on the day of a GSMArena report reveal the physical shapes of three upcoming Apple handsets: the iPhone 18 Pro, iPhone 18 Pro Max and a rumored iPhone Ultra.
The models arrived as shop‑front mockups created from CAD renders sent to case makers — the same files that accessory manufacturers use to design covers — and those dummies are typically reliable for overall shape, dimensions and camera island size.
The clearest detail concerns the iPhone 18 Pro Max. Its overall design appears unchanged from the iPhone 17 Pro Max dummy unit, but the camera island is noticeably thicker. Measurements shown with the dummy put the 18 Pro Max at 11.54mm thick including the camera plateau, versus 11.23mm for the iPhone 17 Pro Max; measured including the cameras, the 18 Pro Max is 13.77mm thick compared with 12.92mm on the 17 Pro Max. Those differences are small on paper but would be tangible in hand and are the primary visible change the leaks identify for Apple’s largest non‑folding Pro phone.
The leak also sketches the contours of Apple’s reported first foldable, presented in the materials as the iPhone Ultra. That dummy appears to forgo MagSafe support and carries only two cameras, a combination that runs counter to expectations that a flagship foldable would adopt the full Pro sensor array. The Ultra’s screen width is said to be basically the same as the Pro Max’s length, and the device is reported at about 111.5mm tall; the screen is still smaller than an iPad mini’s, though thinner bezels would narrow that gap.
Those physical particulars matter because case makers depend on CAD render accuracy: the leaked dummies were produced from the very files that accessory makers use, so case‑fit and port alignments shown in the mockups usually mirror what reaches production. Industry timing in the leaks matches the product cadence Apple has followed — the iPhone 18 Pro, iPhone 18 Pro Max and iPhone Ultra are rumored to launch together at Apple’s annual event in September, while the iPhone 18, iPhone 18e and an iPhone Air 2 are said to arrive only next spring.
The combination of near‑identical footprint and a thicker camera island on the 18 Pro Max points to incremental engineering changes rather than a wholesale redesign. That narrow range of change is exactly the kind of detail that will influence buyers who compare models physically in stores, and it will shape accessory makers’ early offerings; for coverage of how Apple could pair hardware changes with sensor and biometric shifts, see our piece on expected under‑display Face ID for the Iphone 18 Pro Max:
The leaks also create friction between engineering choices and ecosystem expectations. A first Apple foldable described as missing MagSafe is a notable omission: MagSafe has become a standard for charging, mounts and accessories across the lineup, and leaving it off a flagship foldable would force accessory makers to rethink magnetic attachments for a model whose screen geometry and hinge mechanics already pose design challenges. Meanwhile, the Ultra’s pared camera count contradicts assumptions that Apple would treat a foldable as the new platform for expanded optics.
One supplementary detail from reporting around the same time — separate from the dummy‑unit leak — says Apple has tested a 200‑megapixel telephoto sensor in prototypes, but that claim is not part of the primary CAD‑based leak and so does not appear in the dummy units themselves.
If the leaked mockups reflect final hardware, Apple appears set to keep the iPhone 18 Pro Max’s footprint largely the same as the previous generation while making the camera assembly thicker, a small but visible hardware move that will show up in cases and in users’ pockets. The more consequential unresolved question is whether Apple will ship its first foldable without MagSafe; that choice would reshape accessory and charging strategies for the Ultra in ways the dummies already hint at.
