Apple intensifies efforts in the development of its long-awaited foldable iPhone, with a focus on overcoming one of the biggest technical challenges in the segment: the crease in the screen. The company is conducting rigorous testing with multiple variations of ultra-thin glass (UFG), a flexible material designed to minimize the bend marks that plague most competing devices currently on the market.
The goal is to find a precise balance between flexibility and durability. The company’s strategy involves exploring different material thicknesses and compositions to ensure that the internal screen remains smooth and without visible deformations, even after thousands of opening and closing cycles, a quality standard that has become the company’s trademark.
Industry sources indicate that the project, scheduled for launch in 2026, adopts a book format. The device would feature an external screen measuring approximately 5.5 inches and a main internal screen that expands to around 7.8 inches, transforming the smartphone into a small tablet.
Advances in flexible materials
Apple’s research into ultra-thin glass represents the frontier of materials engineering for mobile devices. The technology allows the central area of the display to repeatedly flex, while the side sections maintain the rigidity necessary for everyday use and the protection of internal components. Current tests focus on how the mechanical stress of bending is distributed across the glass surface, seeking a formula that avoids stress concentration at a single point, which causes permanent creasing.
While rival manufacturers have already launched several generations of foldables, Apple takes a more cautious approach, seeking to perfect the technology before its debut on the market. The company explores not only glass but also advanced metal alloys and polymers for the hinge structure, which plays a crucial role in the support and longevity of the flexible panel. The development of proprietary solutions is a priority to ensure a user experience superior to that offered by the competition.
Main technical obstacles
The crease in the internal screen remains the biggest hurdle for the Apple engineering team. Relatórios indicate that current prototypes, although advanced, still have small irregularities visible after intensive use tests.
Another significant challenge is the susceptibility of ultra-thin glass to surface scratches and marks. Encontrar the ideal thickness that offers strength without compromising flexibility is a complex process that directly impacts manufacturing costs and mass production yield.
The company is determined to overcome the limitations seen in models from brands like Samsung and Huawei, setting a new standard of durability and aesthetics for the foldable device category.
The strategic importance of the hinge
The success of the foldable iPhone depends not only on the screen, but fundamentally on the hinge mechanism, which is treated as a high-precision component. Apple is exploring the use of noble materials such as titanium alloys and even liquid metal to build a hinge that is robust, lightweight and capable of operating smoothly for hundreds of thousands of cycles. The design of the mechanism is designed to minimize the bend radius when the device is closed, which reduces pressure on the glass panel and, consequently, the depth of the crease. Além Additionally, the hinge’s engineering needs to ensure there is no room for dust or debris to get in, an issue that plagued early generations of foldables from other brands. Seamless integration between the hinge and display is seen as the key to delivering the premium feel and reliability consumers expect from an Apple product.
Development timeline
Mass production of the foldable iPhone is scheduled to begin at the end of 2026. The official announcement is expected to take place in September of the same year, following the company’s traditional launch calendar.
Strategic partners, such as Foxconn for the assembly and Samsung Display for the supply of flexible OLED panels, are already involved in the preliminary phases of the project.
Engineering validation testing (EVT) has been ongoing since late 2025, with a focus on refining component durability and optimizing the industrial process for large-scale production.
Market analysts project an initial production volume of between 7 and 10 million units for the first year of launch, a number that can be adjusted depending on the manufacturing yield of the more complex components.
Expected device specifications
In addition to the book format, the foldable iPhone is expected to feature a design with reduced thickness when opened, approaching the experience of a conventional iPhone. The chassis must be built with premium materials to ensure structural rigidity, and the speculated price in the North American market varies between US$2,000 and US$2,500.
Preparation for scale production
The Apple supply chain is already mobilizing to secure the critical components needed for large-scale assembly. Fábricas located at China and Taiwan are carrying out final systems integration tests.
The industrial timeline calls for a pilot production phase in early 2026, allowing Apple to make final adjustments to manufacturing processes before accelerating production for global launch.
