iPhone Duo or a used iPhone Pro Max: what should you buy?

Short answer

The iPhone Duo is Apple's first folding iPhone. It costs $1,999 and goes on sale October 23, 2026. Get it if you want a phone that opens into a small tablet. If you want a top iPhone for a lot less, a used iPhone 17 Pro Max from us starts at $870 and a 16 Pro Max at $555. Both have a bigger screen than the Duo when it's closed.

Which one is right for you?

Get the iPhone Duo if…

  • you want a phone that opens into a small tablet
  • you read, draw or watch a lot on it

  • you prefer a phone that doesn't fold
  • you'd rather spend a third of the price

What it really costs you

It's yours

You own the phone outright. There's no contract and nothing to hand back.

Sell it back when you want

After 1 year, 2 years or never. We'll always make you an offer.

Unlike a lease

With a lease or upgrade plan you return the phone and never own it.

Should you wait for the Duo?

Wait if the folding screen is the reason you want a new phone. Nothing else does that. If you mainly want a big screen, a great camera and a battery that lasts all day, a Pro Max already does all three. Sell a used 16 Pro Max back to us after a year and it costs you about $360. The Duo costs $1,999 up front.
