iPhone Ultra concept video shows Apple's 4.5mm foldable

Key Takeaways

- The iPhone Ultra concept measures 4.5mm unfolded, thinner than the 5.6mm iPhone Air
- Apple reportedly plans to launch only Black and White color options initially
- Expected specs include the A20 Pro chip, C2 modem, and 12GB RAM
Jon Prosser of Front Page Tech has published a new concept video of the rumored iPhone Ultra, Apple's long-anticipated foldable iPhone. The video shows a device measuring just 4.5mm when unfolded, which would make it thinner than the already slim iPhone Air at 5.6mm.
The iPhone Ultra concept appears in Black and White, which Prosser claims are the only colors Apple plans to offer at launch. That's a conservative palette for a device expected to cost well over $1,500, but it fits Apple's pattern of launching new form factors with limited options before expanding the lineup.
What does the iPhone Ultra design look like?
The concept video highlights a dual rear camera setup housed in what Prosser describes as an "iPhone Air-inspired camera plateau" with an LED flash. Apple appears to be borrowing design language from its thinnest iPhone rather than the Pro series, which suggests positioning the Ultra as a premium but distinct product line.
The most interesting design claim involves the display crease. According to the video, Apple has developed an "over-engineered" hinge that produces a barely visible crease. This has been Apple's white whale with foldables. Samsung's Galaxy Z Fold series still shows a noticeable crease after six generations, and that visible fold line remains one of the biggest consumer complaints about foldable phones.
The aspect ratio reportedly differs from Android foldables too. While Samsung and others have opted for narrow, tall inner displays, Apple is apparently going wider. This would make the unfolded iPhone Ultra better suited for video content and productivity tasks, though the exact dimensions remain unclear.
What specs are expected?
The rumored spec sheet reads like a flagship checklist: Apple's A20 Pro chip, the new C2 modem (Apple's second-generation in-house cellular modem), and 12GB of RAM. The device will also include the Camera Control button that debuted with the iPhone 16 series.
That RAM figure stands out. Current iPhone 16 Pro models ship with 8GB. Bumping to 12GB suggests Apple expects the larger display and foldable form factor to handle more demanding multitasking scenarios, or that future iOS features require more memory headroom.
Rising memory costs will likely affect iPhone Ultra pricing too
When will Apple announce the iPhone Ultra?
Recent rumors point to a September unveiling alongside the iPhone 18 Pro series. That timeline makes sense. Apple prefers launching major products during its fall event when attention is highest and holiday shopping begins.
But "September" is doing a lot of work here. Apple has reportedly been developing foldable prototypes for years while competitors shipped six generations of devices. The company's pattern is clear: arrive late, but arrive polished. Whether they've cracked the crease problem and hinge durability remains the central question.
Samsung's foldable pricing sets the competitive benchmark for iPhone Ultra
Why is Apple so late to foldables?
Samsung launched its first Galaxy Fold in 2019. Motorola revived the Razr as a foldable the same year. Huawei, Oppo, and Xiaomi have all shipped foldable devices. Apple has sat on the sidelines for six years.
The delay isn't about capability. Apple has the engineering talent and supply chain relationships to build a foldable. The hesitation comes from brand risk. Apple sells products that "just work." Early foldables didn't. Samsung's first Galaxy Fold had screens breaking within days. Even current models have crease visibility issues and concerns about long-term durability.
Apple appears to have waited until its suppliers could deliver a crease-free (or nearly crease-free) display and a hinge that won't degrade over thousands of folds. That's the bet, anyway. Whether this concept video reflects what Apple will actually ship remains speculative.
Logicity's Take
Prosser's track record with Apple leaks is mixed. He's had hits and notable misses. Treat this concept video as directional rather than definitive. The 4.5mm thickness claim is particularly aggressive. For context, that's roughly the thickness of a pencil. Achieving that while housing cameras, batteries, and folding mechanisms would be a genuine engineering achievement. Either Apple has made substantial breakthroughs, or these dimensions will change before production.
Frequently Asked Questions
How much will the iPhone Ultra cost?
Apple hasn't announced pricing. Analyst estimates range from $1,800 to $2,500 based on comparable foldables and Apple's premium positioning.
Will the iPhone Ultra have a visible crease?
According to the concept video, Apple's hinge design produces a "barely visible" crease. This claim hasn't been verified with production hardware.
What size is the iPhone Ultra display?
Exact dimensions haven't been confirmed. Previous rumors suggested approximately 7.9 inches when unfolded, with a wider aspect ratio than Samsung's foldables.
Is the iPhone Ultra concept video official?
No. Jon Prosser's video is based on leaked information and CAD renders, not official Apple materials. The final product may differ substantially.
