iPhone Duo
Apple's first foldable iPhone, from $1,999, with a 7.6-inch inner screen.
It's brand new, so it won't be replaced any time soon.
At a glance
Our take
The iPhone Duo is brand new (on sale since October 23), so there's no successor in sight; a second model is only loosely rumoured for fall 2027. It's the most expensive iPhone by far and the first of its kind, which usually means early-adopter trade-offs.
Note what you give up versus the Pro: two rear cameras instead of three, and Touch ID instead of Face ID. Buy it for the big folding screen, not for the camera.
Research-based: we haven't tested this model ourselves. It's built from Apple's specs, published tests and owner reports.
Pros & cons
What's good
- 7.6-inch folding inner screen plus a 5.4-inch outer screen

- Strong battery claim (up to 44 h video on the outer screen)
What's not
- $1,999 to start
- Two rear cameras, no telephoto
- Touch ID instead of Face ID
- First-generation product
