iPhone Duo — Review Day
Embargo lifted Wednesday, October 21, 2026 · Launches Friday, October 23 · $1,999+
The Duo half-open, from MKBHD's review. Stills and GIFs on this page are pulled from the actual review videos.
The consensus
Loved
- The matte nano-texture inner display — the crease is effectively hidden in normal use
- Hinge feel and build: variable resistance, titanium rails, IP68
- Multitasking that explains itself — split view, paired apps, tent/StandBy modes
- Polish: open/close animations teach the form factor
Mixed
- Battery — tests range from “needs a midday top-up” (Verge) to 40% left at bedtime (Engadget)
- Heat — Verge says hot; 9to5Mac says slightly warm, no performance cost
- Touch ID in the power button — works, but everyone reached for Face ID first
- Matte screen trades a little richness in dark film scenes; fingerprints wipe off harder
Knocked
- Weight: 254 g — the single most common complaint (5 g more than the 18 Pro Max)
- No telephoto — 2x is a sensor crop; main camera sits below the 18 Pro, near the iPhone Air
- 5.4″ cover screen feels cramped; under-display FaceTime camera is weak in low light
- Third-party apps not yet adapted — black bars on the big screen
Battery, tested five ways
| Outlet | Test | Result |
|---|---|---|
| Tom's Guide | Web surfing rundown | 13h 20m — 3+ hrs longer than Galaxy Z Fold 8, well short of 18 Pro Max (17.5h) |
| Engadget | Local video playback | 28h 48m — ~40% left at the end of normal days |
| Gizmodo | Real-world use | 5.5–7.5 hrs screen-on time |
| MKBHD | Mixed open/closed use | Ends the day with 30%+ remaining; efficiency on par with iPhone 17 Pro |
| 9to5Mac | Normal days, no formal test | ~20% left at bedtime |
| The Verge | Heavy use, two reviewers | One needed a midday top-up; the other finished with ~30% after 6.5h screen-on |
Hardware everyone agrees on: 5.4″ cover + 7.6″ 120 Hz inner OLED, ~4,883 mAh dual-cell battery, A20 Pro, 254 g. It's the heaviest iPhone Apple sells — and 39 g heavier than Samsung's Fold.
The video reviews
MKBHD
“iPhone Duo Review: First Generation Fun!”
- Frames it exactly as the title says: genuine delight in the hardware, usual first-gen compromises in software, weight and cameras
- Praises the hinge's variable resistance, the nano-texture screen, and multitasking — paired apps, half-open split keyboard, tent mode
- Battery strong in his testing (30%+ left); cameras, speakers and battery are each “slightly worse” than a Pro — “that's just physics”
- Verdict: regular people and camera-first buyers should pass; if $2,000 doesn't sting, it's a really fun phone
The Verge
“One of Apple's messiest first-generation products in a long time.”
- The skeptic's review: expensive, full of compromises, “incredibly frustrating to use” at times — reaching for a 17 Pro Max felt like relief
- Core problem is inverted vs. Android folds: their inner screens aren't useful; the Duo's outer screen isn't — so you open it constantly, and the apps aren't ready
- Gets hot in third-party apps and long camera sessions; battery split between its two reviewers
- Still fun — compares it to the first MacBook Air. “Most people should wait” at least another year of refinement
Joanna Stern — New Things
“Putting Apple's Folding Phone Through Hell”
- Built a robot (“Hingey”) to fold the Duo 30,000+ times for a hinge durability verdict
- Took it on the Hudson for a camera and bright-sunlight matte-display test against the Galaxy Z Fold
- Loved FaceTime on the big screen; writes a “love letter to Face ID” — Touch ID is her sticking point
- Software bugs were part of the week — her WSJ cut (5 min) adds: the $800 premium over the Pro isn't worth it except for early adopters, and she missed the Action Button daily
CNET
“Late to the Foldable Party, but It Steals the Show”
- Among the most positive takes: the wait was the point — Apple's version arrives more considered than the category it joins
- Shows off Duo Preview: rear cameras for selfies with the cover screen as viewfinder (above, Golden Gate)
- Abrar Al-Heeti: it “took its time getting here, but it's made quite an entrance”
Tom's Guide
“My favorite foldable yet — but there's a catch”
- Mark Spoonauer got real work done on it: video, Slack, spreadsheets on the big screen
- Hardware feels polished; the catch is software — two apps side-by-side is the ceiling, and unoptimized apps mean “a very expensive pair of black bars”
- Advice before spending $2,000: check that the apps you rely on actually use the display
PCMag — Lab Report
“The best foldable for iPhone lovers”
- Eric Zeman: performs like an 18 Pro, lasts almost as long, takes great everyday photos
- Only iPhone with Apple Pencil support — notes and sketches are a Duo exclusive
- Flags the adjustment curve: new button layout, no Face ID, “DuoOS” interface to relearn; price runs $2,000–$3,200

Also in print
- 9to5Mac — “The future is foldable.” Crease shows mainly in bright light over dark content; day ends ~20%.
- Engadget — “A first-class foldable.” Battery counted as a strength.
- Gizmodo — “Waiting to refine foldables was the right move.”
- WSJ — “Too much iPhone, too little iPad.”
