How does the new iPhone Duo design work?

The Apple iPhone Duo is the most innovative device that Apple has announced. With this foldable smartphone, you get a small device and a large screen at once. You can easily open and close it. We'll explain how this works and what it does for you.

Fold iPhone Duo

This is how the folding works

The big advantage of a foldable device is that you have a large and small screen in one. You can comfortably watch videos and read long articles this way, but your device also fits in your pocket. You can easily switch between the small screen on the front and the large screen on the inside. When you open the iPhone Duo, the small screen turns off and you can see what you're doing on the large screen. You don't have to open the apps again.

iPhone Ultra small screen

Closed: small 5.4-inch screen

Closed, the iPhone Duo has a small 5.4-inch screen. The device is a bit thicker and heavier than a non-foldable smartphone, but it still easily fits in your pocket. You can also easily control it with 1 hand. The ratio is different from what you're used to: the screen is almost square. That'll take some getting used to, because some apps look different than on other iPhone models. With vertical videos, like on TikTok or Instagram, you'll see black edges on the side, for example.

iPhone Ultra large screen

Open: large 7.6-inch screen

Open the iPhone Duo and get a large 7.6-inch screen. You can comfortably watch videos, play games, and read longer texts on it. You also have enough space to use 2 apps next to each other. Apple already has experience with this screen size, so the apps work well. For example, they're not broken up in a weird way because they don't fit on the screen like with other foldable devices.
