Apple's First Foldable iPhone Makes Its Debut

Apple officially unveiled iPhone Duo, its first foldable smartphone and a new addition to the iPhone lineup. The device features a book-style folding design with a 7.6-inch inner display and a 5.4-inch outer display, allowing users to transition between a compact smartphone and a larger display for reading, video streaming, gaming, and multitasking. Powered by the A20 Pro chip, iPhone Duo runs iOS 27 with Apple Intelligence and includes an advanced camera system optimized for the new form factor.

iPhone Duo Key Highlights

7.6-Inch Foldable Display

When unfolded, iPhone Duo features a 7.6-inch Super Retina XDR display, Apple's largest iPhone display to date. The inner screen is 50 percent larger than the display on the iPhone 18 Pro Max, providing additional space for browsing, reading, video streaming, and gaming.

When folded, the 5.4-inch outer display provides a more compact smartphone experience. Both displays are designed to maintain visual continuity, allowing users to move between the folded and unfolded modes more naturally.

Split View Multitasking

iOS 27 introduces multitasking features designed specifically for the foldable display, including support for running apps side by side and making better use of the expanded workspace. With Split View, users can open two apps side by side, making it easier to combine activities such as browsing the web while messaging, checking information while taking notes, or managing multiple tasks at once. Combined with Apple Intelligence, these capabilities help improve productivity across work and daily tasks.

A20 Pro Performance

iPhone Duo is powered by Apple's A20 Pro chip and features an advanced thermal management system designed to support sustained performance.

The additional performance is particularly relevant to demanding tasks such as high-frame-rate gaming, multitasking, and on-device AI workloads. Combined with the larger display, the hardware gives iPhone Duo more room to handle demanding mobile experiences.

Foldable Design

The book-style foldable design allows iPhone Duo to combine the convenience of a traditional smartphone with the flexibility of a larger display. Users can easily switch between one-handed operation and a spacious screen depending on the task at hand.

Foldable Ecosystem Enters a New Stage

Apple's entry into the foldable smartphone market further expands mobile device form factors and is expected to support the continued growth of the foldable ecosystem. As hardware, operating systems, and application experiences continue to evolve, more developers are likely to optimize their software for foldable devices, enabling richer experiences across productivity, entertainment, and communication.

As the foldable ecosystem continues to mature, cross-device experiences are also expected to improve. For users who switch between smartphones and PCs, MuMuPlayer Mobile provides a convenient way to remotely control MuMuPlayer running on a PC from a smartphone. As foldable phones introduce larger and more flexible displays, MuMuPlayer is also exploring ways to bring a more suitable experience to these devices through future updates.
