Best Alternatives to iPhone Duo in 2025
The iPhone Duo is Apple's first foldable iPhone, featuring the largest iPhone display ever in a thin, foldable design. With an outer display covering most of a standard iPhone's screen area, a 48MP Dual Fusion camera system, the A20 Pro chip, and all-day battery life, it sets a new standard for foldable phones. However, if you're looking for alternatives—whether due to platform preference, specific features, or budget—there are several excellent options. Here are the best alternatives to the iPhone Duo.
Samsung Galaxy Z Fold 5
As the pioneer of the foldable form factor, Samsung's Galaxy Z Fold 5 offers a refined experience with a large 7.6-inch inner display, a 6.2-inch cover screen, and powerful performance with the Snapdragon 8 Gen 2. Its multitasking capabilities and S Pen support make it a favorite for productivity. While it runs Android, it's the closest competitor to the iPhone Duo in terms of design and functionality.
Google Pixel Fold
Google's first foldable, the Pixel Fold, combines a compact outer display with a wide 7.6-inch inner screen. It boasts the best camera system on a foldable, thanks to Google's computational photography, and runs clean Android with timely updates. If you value camera quality and Google's software experience, the Pixel Fold is a strong alternative.
Samsung Galaxy Z Flip 5
If you prefer a more pocketable foldable, the Galaxy Z Flip 5 offers a clamshell design with a large 3.4-inch cover screen and a 6.7-inch main display. It's less expensive than the iPhone Duo and other book-style foldables, but still delivers flagship performance and a unique form factor. It's ideal for those who want a compact foldable without sacrificing style.
OnePlus Open
The OnePlus Open is a recent entrant that impresses with its thin and light design, a 7.8-inch inner display, and a 6.3-inch cover screen. It features the Snapdragon 8 Gen 2, fast charging, and a versatile triple-camera system. Its near-stock Android experience and competitive price make it a compelling alternative to the iPhone Duo.
Xiaomi Mix Fold 3
Xiaomi's Mix Fold 3 is one of the thinnest and lightest book-style foldables, with a 8.03-inch inner display and a 6.56-inch cover screen. It packs a Leica-tuned quad-camera system, the Snapdragon 8 Gen 2, and fast charging. While availability is limited in some regions, it's a top choice for those seeking cutting-edge foldable technology.
Honor Magic V2
The Honor Magic V2 is renowned for its incredibly slim design, almost matching a regular smartphone in thickness when folded. It offers a 7.92-inch inner display, a 6.43-inch cover screen, and flagship specs including the Snapdragon 8 Gen 2. Its large battery and efficient performance make it a great alternative for users who prioritize portability.
Motorola Razr+ (2023)
For those who love the flip phone style, the Motorola Razr+ (or Razr 40 Ultra) features a large 3.6-inch external display that can run full apps, and a 6.9-inch internal screen. It's stylish, compact, and runs Android. It's a more affordable alternative to the iPhone Duo, especially for users who want a foldable that easily fits in a pocket.
While the iPhone Duo promises Apple's signature ecosystem and performance in a foldable design, the alternatives listed above each bring unique strengths. Samsung's Galaxy Z Fold 5 and Google's Pixel Fold are the most direct competitors, offering polished Android experiences and robust multitasking. For a more compact foldable, the Galaxy Z Flip 5 or Motorola Razr+ are excellent choices. If you seek the thinnest and lightest designs, the OnePlus Open, Xiaomi Mix Fold 3, and Honor Magic V2 are standout options. Ultimately, your choice depends on your preferred operating system, desired form factor, and budget.
