A larger third-generation Duo

Apple hasn't announced a larger iPhone Duo, or any iPhone Duo after the current one. What exists is reporting, almost all of it from Bloomberg's Mark Gurman, that a third-generation model with a bigger inner screen could arrive as early as 2028. The 2027 second generation will likely reuse today's display, Weibo leaker Digital Chat Station said in August.

That's a thin base. MacRumors' iPhone Duo roundup lists a 2027 second generation and no larger model, and we haven't found a report on a bigger Duo from Ming-Chi Kuo, The Information or display analysts such as Ross Young as of Nov 8, 2026. Every claim below is reported, not confirmed. Apple's Sep 9 iPhone Duo announcement doesn't mention a successor.

Today's screens, for comparison

Apple's iPhone Duo spec page lists a 7.6-inch inner display and a 5.4-inch outer display. Apple notes that, measured as standard rectangles, the screens are 7.58 and 5.36 inches diagonally.

A useful caution: before launch, MacRumors' Aug 9 story expected a 7.8-inch inner display and a 5.5-inch cover display. The shipping phone came in smaller on both, so pre-release size figures can miss.

What's reported for the second generation (2027)

Gurman wrote in his Aug 9 Power On newsletter that a second-generation model is planned for 2027, MacRumors reported. In the same story, the Weibo leaker Digital Chat Station said that model will likely reuse the first model's display.

Gurman's Sep 4 Bloomberg roadmap pointed the same way, with a new chip as the only new detail reported for the 2027 model, according to Tbreak's summary of Bloomberg and 9to5Mac. That matches a much older forecast: Ming-Chi Kuo said in May 2025 that a second foldable would follow in 2027, per MacRumors, with nothing about screen size.

The fresher Duo 2 news is about unlocking, not size. In comments on his Power On podcast reported Oct 22, Gurman said prototypes of a successor expected next fall include Face ID under the outer display, though Apple hasn't finalized it, MacRumors reported. 9to5Mac's write-up adds that Face ID could slip to an iPhone Duo 3 if development runs late. The full list lives in confirmed vs reported.

What's reported for a larger third generation (2028)

The first report came on Aug 9. Gurman said a third version could follow as early as 2028 with slightly larger displays inside and outside, but gave no sizes, according to MacRumors. MacRumors called it the first report to lay out plans for a third-generation model.

Gurman added numbers in comments on his Power On podcast reported Oct 22. He said he'd heard Apple is looking at an inner display about half an inch larger, roughly 7.9 to 8.1 inches, and that it wouldn't be a separate Max model, MacRumors reported.

9to5Mac's account of the same podcast puts that screen on an iPhone Duo 3 expected in 2028, with Gurman describing the size as "high sevens, very low eights." He compared the step to the Pro Max going from 6.7 inches on iPhone 15 Pro Max to 6.9 inches on iPhone 16 Pro Max, and said the outer screen may not grow much.

The latest display-supply-chain report about 2028, from TrendForce on Nov 6, is about glass, not size. TrendForce, citing ZDNet Korea, says Samsung and Apple are reportedly weighing an ultra-thin glass with a thinner etched center for 2028 foldables, with a decision expected in Q4 2027. It doesn't say which future iPhone would use the glass or give a screen size.

Where the reports disagree

The outer screen is the clearest conflict. Gurman's Aug 9 report had both displays growing, while 9to5Mac's account of his comments, reported Oct 22, says the outer screen may not grow much.

Timing is softer than headlines suggest. MacRumors' Oct 22 story doesn't name a generation or year for the bigger screen, and the Aug 9 report said the third version could come as early as 2028, which isn't a set date. 9to5Mac also stresses that his sizes are rough estimates.

Gurman's third-generation forecasts have moved before. In September he guessed that Face ID and a telephoto lens would arrive by the third generation, MacRumors reported, and a month later he said Face ID was already in Duo 2 prototypes.

Should a bigger screen change your plans?

On paper, the reported gain is about half an inch on the inner display, as early as 2028, from one reporter. That likely matters less to most buyers than Face ID, which Gurman's comments reported Oct 22 say is being tested for the 2027 model. If you're weighing a purchase now, see who should wait for iPhone Duo 2.
