Apple’s Foldable iPhone Enters Trial Production: What to Expect from the ‘iPhone Fold’
Apple is moving closer to entering the foldable smartphone market, with reports indicating that its first foldable device has officially entered trial production at Foxconn. This milestone, shared by Weibo leaker Instant Digital on April 6, 2026, suggests that the company is steadily progressing toward mass production of the highly anticipated hardware.
The move into trial production signals a critical phase in Apple’s development cycle, highlighting the company’s commitment to bringing a foldable form factor to its ecosystem despite the inherent engineering challenges of the technology.
Launch Timeline: September or December 2026?
While the device is expected to be part of the iPhone 18 lineup in 2026, there is currently a divide regarding the exact release date. Some reports suggest a simultaneous launch with the iPhone 18 Pro in September 2026. However, other industry analysts point toward a slight delay.
Barclays analyst Tim Long has reported that the foldable iPhone may not reach consumers until December 2026. This sentiment was partially corroborated by Bloomberg’s Mark Gurman, who noted that the device will likely arrive slightly later than the Pro models. Gurman attributed this potential shift to the complexities of foldable production and Apple’s historical tendency to launch major new design iterations—such as the iPhone X—later than its standard flagships.
Design and Build: A ‘Book-Style’ Approach
After years of experimenting with various form factors, including a clamshell design similar in size to current iPhones, 2025 rumors indicate that Apple has settled on a book-like design. This configuration features an outer display and camera for use when closed, which opens to a larger, iPad mini-sized internal display.
According to early reports, the device is expected to feature a 7.8-inch internal screen and a 5.5-inch external display. To address the common issue of screen creases, Apple is expected to use Ultra Thin Glass (UTG) to maintain the hinge crease minimal.
The build quality will likely leverage a mix of premium materials. The casing is rumored to be a titanium alloy, with a hinge composed of stainless steel, titanium, and liquid metal components. Analyst Jeff Pu suggests the frame will combine titanium for stress-bearing parts to prevent bending, while aluminum will be used in other areas to assist with heat dissipation and weight reduction.
Hardware Specifications and Software Integration
The foldable iPhone is expected to ship with significant hardware upgrades to support its larger display and multitasking capabilities. Rumored specifications include:
- Memory and Storage: 12 GB of RAM and up to 1 TB of storage.
- Battery: A capacity ranging between 5,000 and 5,500 mAh.
- Cameras: A dual-lens rear camera system and a single front-facing camera.
- Authentication: Analyst Ming-Chi Kuo believes Apple may opt for a Touch ID side button instead of Face ID to save internal space and maintain a thinner profile.
On the software side, the device is expected to run iOS 27, which will be specifically optimized for foldable experiences. Current reports indicate that the device will likely run a redesigned version of iOS rather than iPadOS.
Pricing and Potential Naming
While the device has been widely referred to as the “iPhone Fold,” some reports suggest Apple may instead name the device “Ultra.”
Pricing remains a point of speculation, though estimates have shifted over time. While earlier projections placed the starting price around $2,399, more recent reports suggest a more aggressive starting price of $1,999.
