Is Apple’s first foldable iPhone being built around a 4.5mm unfolded profile before anything else?
That is the real question raised by a newly leaked hands-on video of a foldable iPhone Ultra dummy model from a Chinese factory. The unit is not a finished product, and the source repeatedly warns against reading too much into it. But the shape, thinness, and button placement line up closely enough with earlier rumors to make the leak more than visual noise, according to Notebookcheck.
If the device ships near the rumored dimensions, Apple would not be entering foldables as a cautious experiment. It would be trying to make the category look premium, thin, and inevitable.
Does the leaked dummy show a real iPhone Ultra design direction?
The video reportedly shows the same white iPhone Ultra replica that first appeared in a leaked image, this time from more angles. That matters because a still image can hide proportions. A video makes the edges, hinge area, button placement, and overall silhouette harder to fake convincingly.
Still, this is a dummy model, not a working iPhone. Dummy units usually speak to external design: rough dimensions, button locations, camera island placement, hinge geometry, and accessory fit. They do not prove battery capacity, display quality, hinge durability, software behavior, or final materials.
Notebookcheck describes the unit as “particularly low-quality,” which is the right caveat. A bad dummy can still reflect accurate measurements. It can also reflect incomplete supply-chain assumptions.
The most interesting visible detail is thinness. Previous rumors said Apple’s foldable could measure 4.5mm when opened, and the dummy in the video reportedly looks consistent with that direction. The video also appears to show volume buttons placed on top, a layout Notebookcheck says had been rumored for some time.
That placement is awkward on paper. It also hints at the deeper design problem Apple faces: a foldable iPhone is not just a thin iPhone that bends. Every button, camera, hinge, biometric sensor, and display layer has to make sense in both folded and unfolded modes.
Is 4.5mm thinness the headline, or the trap?
The 4.5mm figure is provocative because unfolded thickness is the number that makes a foldable look futuristic. It is also the easiest number to overrate.
A related Notebookcheck report on leaked schematics from a case manufacturer put the unfolded chassis at about 4.7mm, with a 9.4mm folded profile excluding the rear camera hump. The same report said the maximum thickness could reach about 13.9mm once the camera assembly is included.
That distinction matters. A foldable can look impossibly thin when open and still feel chunky in a pocket if the folded profile, hinge gap, camera bump, or weight disappoints.
| Rumored / leaked detail | Reported figure or claim | Why it matters |
|---|---|---|
| Opened thickness | 4.5mm rumor / about 4.7mm in schematics | Defines the “wow” factor when unfolded |
| Folded thickness | 9.4mm excluding camera hump | Determines pocket feel more than opened thinness |
| Maximum thickness | About 13.9mm with camera assembly | Shows the camera bump may dominate real-world handling |
| Rear cameras | Two 48MP sensors rumored | Suggests Apple may still be prioritizing flagship camera hardware |
| Color options | Black and white | Points to a restrained first-wave finish lineup |
The engineering trade-off is straightforward. A thinner body leaves less room for battery volume, thermal headroom, structural reinforcement, display layers, and hinge mechanisms. The source does not provide battery specs, weight, or heat data, so those remain open questions.
Hinge behavior is another unresolved issue. A thin foldable would still have to prove that its mechanism, display surface, and folded profile can survive daily use without turning the design story into a durability story.
Why would Apple accept a strange button layout?
The rumored button placement may be the most revealing design clue in the leak.
Notebookcheck says the video shows volume buttons in the long-rumored top position. Related schematics also described a layout where the buttons could end up in an unusual orientation when the device is unfolded and held like a small tablet.
That suggests Apple may be prioritizing internal packaging and hinge geometry over familiar iPhone ergonomics. If true, this is not a minor detail. Button placement is one of the few physical interactions users repeat dozens of times a day.
The related schematic leak described an “Android-style” punch-hole selfie camera on the inner display, placed in the left corner. That would be a notable visual departure from the current iPhone identity if it survives into production.
MLXIO analysis: if those details hold, Apple may be trading some traditional iPhone identity for foldable practicality. That is not failure. It is a sign that the form factor is forcing decisions Apple cannot solve with branding alone.

Is this an Apple product story or a supplier-chain story?
Right now, it is both.
The latest video reportedly comes from a factory setting. The related schematic leak was sourced from a case manufacturer. Those are classic signs that physical dimensions may be circulating before Apple confirms anything publicly.
Accessory makers need early measurements. Case molds, hinge clearance, camera cutouts, and button access cannot wait until launch week. That does not mean every dummy is accurate. It does mean the supply chain may be converging around a shared external shape.
The rumored external-design picture is narrowing:
- Unveiling: Rumored for September, though Apple has not confirmed timing
- Thickness: Around 4.5mm to 4.7mm unfolded, based on separate reports
- Folded profile: About 9.4mm excluding the rear camera hump
- Camera assembly: Maximum thickness reportedly around 13.9mm with the camera area included
- Rear cameras: Two 48MP sensors rumored
- Selfie camera: Punch-hole placement described for the inner display
- Colors: Black and white options reported
None of that is confirmed by Apple. But the combination points to a device positioned above the standard Pro tier, not beside it.
Samsung, Honor, and Oppo are the named comparison set in the related source, specifically around thin foldable designs. That makes Samsung the most visible reference point for Apple’s eventual entry; for our related coverage, read Galaxy Z Fold 8 Leak Reveals Samsung’s iPhone Ultra Bet.
Would a foldable iPhone Ultra actually change the premium phone market?
Only if Apple makes the unfolded mode feel essential.
An Ultra-branded foldable iPhone cannot survive on novelty. The buyer would need a reason to open it every day: reading, editing, multitasking, video, work apps, or a tablet-like mode that feels meaningfully better than a slab iPhone.
The source does not confirm iOS features, multitasking changes, app behavior, battery life, or repair pricing. Those are the real product questions. Hardware leaks can show the shell. They cannot show whether the software makes the shell worth carrying.
MLXIO analysis: the most important market effect would not be that Apple “joins foldables.” It would be that Apple sets a new top tier for iPhone design ambition. If the Ultra name sticks, the device would likely serve as a halo product: expensive, scarce, visually distinct, and judged less against normal iPhones than against the promise of replacing two screens with one folding device.
That is also the risk. A thin chassis, odd buttons, a large camera plateau, and first-generation hinge expectations create many ways to disappoint.
Which evidence would confirm this leak is more than a dummy?
The next credible signals would be higher-quality design models, consistent case-maker dimensions, matching camera cutouts, and repeated confirmation of the 9.4mm folded profile. A later leak showing display behavior, crease visibility, or software continuity between the outer and inner screens would matter more than another shell video.
The thesis to test is simple: Apple appears to be aiming for thinness and premium positioning first. If future leaks confirm a near-4.5mm opened profile, a practical inner display layout, and convincing hinge behavior, the foldable iPhone Ultra could reset expectations for the top of the iPhone line.
If the next evidence instead points to compromise — visible crease, awkward handling, weak folded usability, or a camera bump that overwhelms the thin chassis — the Ultra risks becoming a very expensive design exercise rather than Apple’s next major iPhone category.
The Bottom Line
- The leak suggests Apple may prioritize an extremely thin 4.5mm unfolded design for its first foldable iPhone.
- A dummy model can reveal external design direction, but it does not confirm final hardware, durability, or software features.
- If accurate, Apple’s foldable strategy appears aimed at making the category feel premium rather than experimental.
