iPhone Fold: Apple's First Foldable, Everything We Know

The iPhone Ultra is Apple's first foldable phone — a 7.8-inch book-style device with Touch ID, a crease-minimizing hinge, and a starting price north of $2,000. It could also launch later than the iPhone 18 Pro. Here's what the leaks reveal.

What Is the iPhone Fold?

The iPhone Ultra — as the foldable model is currently being called — is Apple's entry into the foldable phone market that Samsung, Google, and others have been competing in for years. Unlike Samsung's Galaxy Z Fold line, which folds into a tall, narrow shape, Apple's foldable is rumored to use a book-style design that opens to a near-square display.

The name is not confirmed. Some reports call it "iPhone Fold," others "iPhone Ultra," and still others suggest it may get a completely new naming convention to distinguish it from the traditional iPhone lineup. For this article, I'll use "iPhone Fold" and "iPhone Ultra" interchangeably.

Display: Two Screens, iPad-like Ratio

The iPhone Fold is expected to have two displays:

The 5.5-inch external display is what you see when the phone is closed. This is the screen you'd use for quick tasks — checking notifications, making calls, replying to messages. It's larger than the Galaxy Z Fold 6's 6.3-inch cover screen, but Apple's approach appears to be a more compact, pocketable form factor.

The 7.8-inch internal display is the main attraction. When you open the phone like a book, you get a full-size tablet-style display. The 4:3 aspect ratio is the same as the iPad, which means the unfolded experience will feel very similar to using an iPad mini — roughly 8.3 inches diagonally. Apple's app developers already optimize for this aspect ratio across the iPad line, which should give the iPhone Fold a software advantage over competitors.

Touch ID Returns, Face ID Doesn't Fit

In one of the most interesting design decisions, the iPhone Fold will reportedly use Touch ID instead of Face ID. The reason is purely physical: the TrueDepth camera system that powers Face ID requires a certain depth, and the iPhone Fold is simply too thin when closed to accommodate it.

Apple will use a side-mounted Touch ID sensor, integrated into the power button — similar to the approach used on the iPad Air and iPad mini. This will be the first flagship iPhone to use Touch ID since the iPhone SE (3rd generation) and the first to use side-mounted Touch ID since... well, ever. It's a notable departure for Apple's top-tier device.

For users who have grown used to Face ID, this will be an adjustment. Touch ID is arguably faster when the phone is flat on a table, but less convenient when the phone is mounted or hands-free. The trade-off is the thin foldable design, which simply can't physically fit the Face ID hardware.

The Hinge and Crease Problem

The biggest challenge for any foldable phone is the crease — the visible fold line where the display bends. Samsung has improved this significantly over six generations of the Z Fold, but there's still a noticeable dip when you run your finger across the screen.

Rumors suggest Apple has developed a specialized hinge mechanism designed to minimize crease visibility. The company has reportedly spent years perfecting this hinge, which is one of the reasons the foldable iPhone has taken so long to reach market.

Whether the crease will be completely invisible or just less noticeable than competitors remains to be seen. Early hands-on reports from those who claim to have seen prototype units suggest Apple's crease management is significantly better than Samsung's, but it's unlikely to be truly invisible under all lighting conditions.

Cameras: Two Lenses, Not Three

The iPhone Fold is expected to have a two-lens rear camera system instead of the three-lens setup on the Pro line. The thinness of the device when closed limits the depth available for camera modules, so the telephoto lens appears to be dropped.

The main camera is rumored to be a 48MP wide sensor, likely paired with an ultrawide. This would give foldable iPhone owners most of the photography capabilities of a standard iPhone, minus optical zoom. Given the $2,000+ price point, some buyers may be disappointed by the camera compromise — but Apple's argument is likely that the foldable display is the premium feature, not the camera.

A20 Chip and Dual Batteries

The iPhone Fold is expected to use the 2nm A20 chip — the same process node as the A20 Pro in the iPhone 18 Pro, but potentially with fewer GPU cores or a slightly different configuration to manage thermals in a thinner chassis.

Battery-wise, the foldable is expected to use dual batteries — one in each half of the phone. This is a common approach for foldables, as it allows the battery to be distributed across the two halves rather than requiring one thick battery pack. The total capacity is expected to be competitive with the iPhone 18 Pro, though the larger display may drain it faster.

Price: $2,000 and Up

The premium pricing reflects several factors: the custom hinge mechanism, the flexible OLED display panel (which is significantly more expensive than a standard rigid panel), and the lower production volume compared to standard iPhones. Apple may also be positioning the foldable as an ultra-premium product, not a mass-market device.

Release Date: September or Later?

This is where things get uncertain. Reports from the supply chain have surfaced about manufacturing issues with the foldable, which could delay the actual launch even if the device is announced in September.

Apple has a historical precedent for staggered foldable-style launches. When the original iPhone X was announced in September 2017, it didn't actually go on sale until November — a two-month gap. The iPhone Fold could follow a similar pattern: announced at the September event alongside the iPhone 18 Pro, but with actual availability pushed to October or November.

This would give Apple time to build inventory and ensure the hinge mechanism meets quality standards, while still capturing the September announcement hype and media cycle.

How It Compares to Samsung's Foldables

Samsung has a multi-year head start in foldables, but Apple's advantage is software. With a 4:3 aspect ratio that matches the iPad, the iPhone Fold will benefit from years of iPad-optimized apps. Samsung's foldables have struggled with app optimization because the unusual aspect ratios don't match any other common form factor.

The iPhone Fold will also have Apple's ecosystem advantage — Continuity, Handoff, AirDrop, and the seamless integration between iPhone, iPad, Mac, and Apple Watch. For users already deep in Apple's ecosystem, the foldable could feel like a natural extension rather than a novel experiment.
