iPhone Duo Review: What the Spec Sheet Says Before You Queue

This is a review based on the specifications, not on hands on testing. We have not used the iPhone Duo ourselves, so the verdict below is about what the spec sheet and the reported details suggest. Once review units are in independent hands, we will test it properly and update this piece.

The key specifications

The Duo has a 7.6 inch inner screen with a 120 Hz refresh rate, and it runs on Apple's A20 Pro chip with 12 GB of RAM. Storage starts at 256 GB and goes up to 2 TB. The main camera is a 48 MP sensor. The EU energy label reports a total battery capacity of 4,883 mAh, which is a useful reference point for battery life in a device this thin.

Where it looks strong

The large inner screen and the 120 Hz refresh rate are the main reasons to buy a foldable, and the Duo offers both. The storage options are generous, with 2 TB at the top end, which few phones in any category can match. Apple's chip and software support also point to a long useful life, which matters for a device at this price.

Where it asks for a compromise

The starting price of $1,999 puts the Duo at the top of the market, and the battery figure of 4,883 mAh is below the 5,000 mAh in the Galaxy S26 Ultra. The supply situation is also a practical cost, since waiting months for delivery is a real limit on who can buy it now. And a single 48 MP camera, with no telephoto or ultrawide lens listed in our data, will be a step back for buyers who rely on zoom.

Verdict from the specifications

If you want an Apple foldable and can accept the price and the wait, the Duo's screen and storage make a compelling case. If battery life and camera range matter more to you, a conventional flagship such as the Galaxy S26 Ultra is the stronger choice on paper. We will update this review after hands on testing.
