A Foldable iPhone That Wants to Replace Your iPad Mini
The foldable iPhone design refers to Apple’s rumored iPhone 18 Fold or iPhone 18 Ultra, a Passport-like device with a 7.8-inch inner display, ultra-thin chassis, and nearly creaseless display technology that aims to sit between a traditional iPhone and an iPad Mini in both size and function.
This iPhone 18 Fold leak makes one thing clear: Apple is not chasing Samsung’s tall, narrow foldables. The dummy unit feels wider than a regular iPhone and is compared directly to a BlackBerry Passport, only without the physical keyboard and with a smaller footprint. Once unfolded, it reportedly feels like a mini tablet, similar to a Huawei-branded large-screen phone, pointing to a device designed for reading, multitasking and media rather than one-handed thumb use. In other words, Apple’s first foldable looks like a deliberate strike at the “phone that can be your tablet” idea, not a novelty flip on the existing iPhone slab.
Passport-Like Form Factor: Wider, Shorter and Deliberately Non-Samsung
The most interesting part of the foldable iPhone design is its Passport-like silhouette. According to early hands-on impressions with the dummy hardware, the device feels wider than a standard iPhone, echoing the BlackBerry Passport’s squat, wide stance but in a more compact shell. That matches earlier CAD leaks pointing to an inner screen closer to an HD-like aspect ratio, not the elongated frames seen on rival foldables.
This is a quiet but important rebellion against the Samsung-style book fold. While the Galaxy Z Fold line prioritises a tall outer display that still behaves like a phone, Apple’s outer panel reportedly measures 5.5 inches at 2,088 x 1,422, feeding into a 4:3, iPad-like 7.8-inch inner display. The result is a foldable phone display that favors tablet tasks: note-taking, split-screen apps, and landscape video. It feels compact and solid in the hand and is described as thin for a foldable smartphone, comparable in slimness to a current Samsung Fold model. Apple appears to be designing a small tablet that happens to fold into a phone, not the other way around.
Ultra-Thin, Nearly Creaseless: Apple’s Biggest Flex Is the Screen
Apple is clearly treating the foldable phone display as the hero feature, and the tradeoffs prove it. The inner panel reportedly measures 7.8 inches at 2,713 x 1,920, using a 4:3 aspect ratio—the same proportions as an iPad—and sits at only 4.5mm thick when open, thinner than the 13-inch iPad Pro’s 5.1mm chassis. Closed, the device is said to measure 9mm to 9.5mm, making this an ultra-thin foldable phone rather than a chunky first attempt.
The company has reportedly spent years pursuing creaseless display technology “regardless of cost,” aiming to avoid the visible fold line that undermines every other foldable. According to one leak, “The result is a crease depth under 0.15mm with a fold angle under 2.5 degrees, shallow enough to be nearly invisible to the eye and imperceptible to the touch.” Apple is said to have developed a new optically clear adhesive that flows into microscopic irregularities during bending, cutting light scattering at the fold. Combined with Samsung-supplied panels that integrate touch sensors directly into the display, trimming thickness by about 19 percent, this design puts the screen ahead of everything else—including some hallmark iPhone features.
Goodbye Inner Face ID: The Cost of Being This Thin
To hit that 4.5mm open thickness, Apple is reportedly giving up something it has guarded for years: inner-screen Face ID. The iPhone 18 Fold leak suggests the foldable iPhone skips Face ID on the inner display, instead using Touch ID in the power button because the full TrueDepth camera system will not fit in the ultra-thin chassis. That is a startling move for a company that has kept Face ID on every flagship since the iPhone X.
From a user perspective, this will divide opinion. Power-button Touch ID can be convenient in laptop-style use, especially when the device is half-folded on a desk. But it also means biometric behavior will differ between the outer and inner displays if Apple keeps Face ID outside and Touch ID inside. Meanwhile, the dummy unit shows a Camera Control button with the power button above it, volume keys near the top edge, and a USB‑C port between speaker grilles. On the camera side, early prototypes point to a dual-camera system at the rear and two separate selfie cameras—one on the outer display and one in the upper-left corner of the inner screen. What we still do not know is how this ultra-thin chassis will handle heat and performance over long sessions.
A Pocket iPad Mini? What the 7.8-Inch Screen Means for Apple’s Lineup
The 7.8-inch inner display is not just about besting rival foldables; it is a direct shot at the iPad Mini. The unfolded screen area puts this device in direct competition with the iPad Mini’s 8.3-inch display, but in a body that folds to roughly half the thickness. One report bluntly states, “The foldable iPhone Ultra’s 7.8-inch display doesn’t just rival other foldables. It directly threatens Apple’s own iPad Mini.”
With iOS 27 reportedly adding new “foldState” and “angleDegrees” APIs so apps can react to hinge angle and support true split-screen multitasking, the software vision is clear: this is meant to feel like a tiny Mac or iPad that happens to make calls, not a giant iPhone. Leaks suggest Apple plans to announce the device alongside the iPhone 18 lineup, with a launch pattern similar to the iPhone X—unveiled in September, but with pre-orders and shipping pushed later due to limited early production, and suppliers instructed to prepare around 10 million units. If that happens, the foldable iPhone design will not remain a niche experiment for long; it will define a new middle space between phones and tablets and force Apple to decide what, exactly, the iPad Mini should be in a world where your phone can unfold into one.
