iPhone Duo vs iPhone 18 Pro: Foldable or Pro?

Apple's foldable has nearly the same outer screen area as the 18 Pro, and opens into a tablet. Here is the trade-off.

iPhone Duo vs iPhone 18 Pro

A tablet that folds, or a light phone with the better camera. Get the iPhone Duo if you want a 7.6-inch screen you can pocket. Get the iPhone 18 Pro for the full Pro camera with a 4x telephoto, Face ID and a phone that's 43 g lighter.

Round by round

ScreenDuo

Open, 7.6 inches with Split View. Closed, the 5.4-inch screen has about 90% of the 18 Pro's screen area, so it still works as a normal phone.

Camera18 Pro

Three 48MP cameras with a 4x telephoto and an 18MP selfie camera. The Duo has two cameras and 2x zoom.

Weight18 Pro

211 g against 254 g. That 43 g gap is about seven loonies.

BatteryDuo

Up to 44 hours of video on the Duo's outer screen, 31 open. The 18 Pro does 36.

Unlock18 Pro

Face ID on the 18 Pro. Touch ID on the Duo.

The Duo is for screen people. The 18 Pro is for camera people. Figure out which one you are.

Skip it if

Skip the iPhone Duo if

  • You zoom a lot
  • You want a light phone
  • You want Face ID

Skip the iPhone 18 Pro if

  • You want one device for phone and tablet
  • You read or work in two apps side by side
  • You want the longest battery of the two

SOur take

For most people, the 18 Pro is the easier phone to live with: lighter, better camera, nothing to unfold.

The Duo is for people who keep wishing their phone was bigger. If that's you, nothing else Apple makes comes close.
