Is Apple’s foldable iPhone Duo worth $2,000? See how it stacks up against other foldable phones.

The iPhone Duo offers six distinct modes for users to utilize, depending on the position of the hinge and the angle of the displays. This unique feature sets the iPhone Duo apart from traditional smartphones.

1. Closed mode: In this basic mode, the hinge is shut, and only the exterior cover display is accessible. The 5.4-inch screen is used for quick tasks such as checking notifications, sending messages, making calls, or using Apple Wallet.

2. Open mode (horizontal/landscape): When the iPhone Duo is fully opened, the larger 7.6-inch display becomes the primary screen, positioned in a horizontal/landscape orientation. This mode is ideal for entertainment and productivity, including watching movies, gaming, drawing, or running multiple apps simultaneously. The under-display camera in the top-right corner allows for smooth FaceTiming and other video calls.

3. Open mode (vertical/portrait): When the iPhone Duo is flipped into a vertical/portrait orientation, the navigation bar moves to the bottom, and the taller aspect ratio allows for better reading experiences. This mode is perfect for reading ebooks, articles, and vertical videos. It also enables the use of an Apple Pencil and supports StandBy Mode when propped on a flat surface.

4. Book mode (partial fold): In this mode, the iPhone Duo is almost fully open, resembling an open book. The crease running down the middle of the screen is accommodated by moving on-screen elements away from it. This mode provides a natural book-like reading experience and is helpful for multitasking with an Apple Pencil.

5. Tabletop mode (90-degree angle fold): The iPhone Duo can be folded around a 90-degree angle, positioning the phone like a laptop. The screen is split down the crease, allowing for stable support for hands-free video calls, long-exposure or timed photos, and streaming content while keeping other app elements accessible.

6. Tent/Standing mode: Lastly, the iPhone Duo can be folded into a V-shaped tent, with the exterior display facing outward. The interior screen turns off, and the outer display remains active. This mode is perfect for viewing content in a tent-like setup or using the phone as a presentation tool.
