iPhone Duo Reviews Are In: 24 Reviewers, One Great Hinge, and the Face ID Everyone Misses

中文版 Chinese version

Prices, scores, and test results below are as reported by reviewers on October 21, 2026 — a snapshot, subject to change. The iPhone Duo ($1,999 for 256GB, up to $3,199 for 2TB) goes on sale October 23, 2026; new orders have already slipped to January 2027 delivery.

The first folding iPhone has been reviewed — by just about everybody, all at once. This post reads across 24 of those reviews, from MKBHD and Mrwhosetheboss to The Verge, Joanna Stern’s WSJ review, Engadget, Gizmodo, CNET, and PCMag, and pulls out what they collectively establish: the rare points of total consensus, the genuine disagreements, and the measured numbers that separate them.

The scoreboard

That clustering — enthusiastic hardware scores, mid-range overall scores — is the whole story of this launch in miniature.

Consensus #1: the hinge and the screen are the best in the business

No reviewer pans the hinge; most lead with it. It holds any angle (the “poses”: tent mode, laptop mode, half-open video calls), increases resistance as it opens, closes with a satisfying magnetic snap, and opens completely flat to 180°, which most Android book foldables still don’t do. Brian Tong calls it “the best hinge on a foldable that I’ve experienced”; PCMag compared it against four rival 2026 foldables on the desk and found none “this strong and smooth.”

The durability evidence is better than marketing copy. Joanna Stern and designer Aron Cohen built a folding robot — “Hingey,” a servo motor plus 3D-printed parts — and folded the Duo 32,640 times over four nights. A calibrated gauge showed the hinge very slightly stiffer; in the hand, Stern couldn’t tell the difference. Gizmodo’s Raymond Wong contributed an unplanned test: his unfolded review unit slipped down wet, rain-soaked steps and came away with minor frame scuffs and both screens intact. The phone is also IP68 — in the US, only the Pixel 11 Pro Fold matches a book foldable on that.

The 7.6-inch inner display’s nano-texture matte finish is the other universal praise point — Mashable calls it “the nicest phone display I’ve ever seen,” MrMobile “a masterpiece,” WIRED “the star of the show.” Its main job is hiding the crease, and it works: the shared verdict is that the crease is essentially invisible head-on, findable at angles or on white screens, and always feelable — 9to5Mac’s Chance Miller has the roundup’s most honest line: anyone who says the crease is invisible is misleading you, and anyone who says it’s a problem is similarly misleading you. The agreed trade-off: matte means slightly less deep blacks and less vivid color than the glossy 5.4-inch cover screen. Nearly everyone concludes Apple made the right choice anyway — and notes the e-paper-like feel bodes well for the Apple Pencil support arriving with iOS 27.2.

Consensus #2: everybody misses Face ID

MacStories titled its roundup “…and Everybody Misses Face ID,” and it is not an exaggeration. The Duo has Touch ID in the power button — deliberately slower, per Apple (via Engadget: consistency with Mac/iPad Touch ID behavior, plus time to surface lock-screen notifications). The roll call: MKBHD — “Face ID is going to be the number one thing people miss.” Mrwhosetheboss — “a tiny bit of extra friction, 50 times a day,” worse with wet or oily fingers. Stern registered all five fingerprints in one hand and still fumbled unlocks after a week: “Face ID, I cannot tell you how deeply I miss you.” 9to5Mac calls the switch “the hardest thing to get used to.” The recurring workaround, from several reviewers: enable Apple Watch unlock. This is the single most-cited daily friction in all 24 reviews — a deliberate Apple choice that every reviewer wishes Apple hadn’t made.

Consensus #3: the apps aren’t ready

MKBHD’s review runs a literal tally of optimized vs. unoptimized apps, and the wrong column is longer: Spotify, Google Maps, Discord, X, Google Calendar, Telegram, Google Docs and several games letterbox or shrink on the inner display at review time, while Netflix, Instagram, and OpenTable were ready, and Apple’s own apps (Mail, Notes, App Store) use two panes well. Mrwhosetheboss names Google Docs; Engadget calls Telegram “a big offender.” CNN’s advice is simply to wait for developers. The one mitigating data point: Max Weinbach tracked optimization going from almost none to nearly half of apps in about six days — the gap is closing fast, and with new orders backordered to January, WIRED argues the wait may fix the software before most buyers even get the phone. But today, iOS 27’s split view is also more limited than Samsung’s: 50/50 splits only, top/bottom in portrait, and WIRED found “wasted space” — a right-rail layout that leaves dead zones in many apps.

The weight problem nobody waves away

The Duo is 254g and 11.3mm folded — the heaviest iPhone ever, and more than 25% heavier than the Galaxy Z Fold 8’s 201g (which is also thinner: 9.7mm folded, 4.5mm open, vs the Duo’s 5.2mm unfolded). Engadget: “a bit like an anchor in your pocket.” MKBHD: “you would be happy if it were 20% lighter.” Even the fans list it as a top con. The mitigations reviewers agree on: it’s well balanced when open, no worse in the pocket than an iPhone 18 Pro Max (249g), and the titanium frame, glass back, and vapor chamber explain where the grams went. WIRED’s prediction is the consensus one: Apple will shave it in generation two, the way Samsung did.

Performance: the chip is not a compromise — the cooling is contested

On raw silicon there is no foldable tax. Gizmodo’s Geekbench 7 averages (three runs):

The Duo matches its slab sibling and beats the Fold 8 by 22% single-core and a striking 71% on GPU. Where reviewers split is sustained performance. Gizmodo found the vapor chamber “does a solid job” with no material slowdown; 9to5Mac: hotter than the 18 Pro, “but not in a way that impacts performance.” The other camp has data: HTX Studio’s 30-minute gaming test hit 46.5°C (vs ~43–44°C for the 18 Pro line), with frame rates ~20% lower and brightness throttling from 300 to 185 nits; The Verge saw visible lag once the dual-screen camera warmed the phone; Stern had to end a FaceTime call because the phone became a “hand warmer” (Apple told her the warmth is the thermal system working as designed). Tom’s Guide’s 3DMark stability score — Duo 75.9%, Pro Max 79%, Fold 8 72% — suggests the truth is “slightly worse than the Pro, better than the rival,” with your mileage depending heavily on gaming and camera loads.

The sharpest disagreement: battery life

Reviewers cannot agree whether the battery is a strength or the phone’s weakest point, and the lab numbers show why — methodology is destiny:

Real-world reports scatter across the whole range. Engadget routinely ended days at 40%+ (“wouldn’t be surprised if people can go two days”); WIRED ~40% at bedtime; MrMobile 10–20% left after 17-hour heavy days with gaming and camera sessions; CNET’s heavy day ended at 29% — and its 45-minute mixed endurance test left the Duo at 99% vs the Fold 8’s 93%. Then there is The Verge: Nilay Patel needed a midday charge on a normal workday and concluded the Duo “doesn’t seem ready to last a full day of heavy use”; PetaPixel calls it “just barely good enough.” The likely driver of the split is how much of the day runs on the power-hungry inner screen — CNET notes it drains fastest — which means your own usage pattern (cover-screen triage vs. everything unfolded) predicts your experience better than any single review does.

Cameras: “good enough” is the ceiling of the praise

Two 48MP rear cameras (main + ultrawide), 2x crop zoom, no telephoto, 10x digital max, no ProRAW/ProRes or variable aperture. Mrwhosetheboss calls the missing telephoto a personal dealbreaker at $1,999; Gizmodo calls its absence “absurd” on the most expensive iPhone ever, while conceding Pro cameras would have added weight and price. The Verge puts the main sensor a class below the 18 Pro (Air-class, with heavier sharpening that makes fine detail “crunchier” and weaker low-light color). Engadget and MrMobile dissent upward — Engadget found the Duo keeping up with and sometimes beating the Fold 8 in low light, and MrMobile calls it “the best camera on a foldable in the US” on the strength of Apple’s processing; photographer Tyler Stalman splits the difference: pros will see the gap to the 18 Pro, most people won’t. Everyone agrees on two things: video is excellent (better stabilized than Android flagships, per Gizmodo), and the ~4MP under-display inner camera is for FaceTime only — MKBHD’s word for it as a photo camera is “trash.” The consolation, per The Verge: with a cover-screen preview, “every camera on this thing is a selfie camera.”

Smaller fights worth knowing about

• The 5.4-inch cover screen. CNET: “doesn’t feel cramped… the keyboard is roomy.” Engadget: great one-handed size. The Verge: “like having an iPhone 5 in a world of iPhone Pro Maxes.” Brian Tong: “too small,” iPhone mini vibes. Photographer David Imel dissents from both: the small screen is a feature — it makes the Duo “the most task-oriented iPhone ever,” forcing commitment to the big display for anything substantial.
• Speakers. MacStories calls this “the most surprising disagreement of the bunch”: PetaPixel (“knocked this one out of the park”), Brian Tong (“best sounding foldable I’ve experienced”), Gizmodo and Tom’s Guide (terrific) against 9to5Mac (“thinner and quieter” than the 18 Pro) and MKBHD (slightly-worse speakers are inherent foldable physics).
• Ergonomics nits. Volume buttons moved to the top edge (Stern keeps hitting the wrong one mid-call); the right-rail controls can’t be mirrored, prompting CNET’s “condolences to all the lefties.”

Durability and repair: early, encouraging, priced

Beyond the robot and the staircase: the matte inner layer can be peeled if picked at — Apple replaces it for $49; a full inner-screen replacement without AppleCare+ is reported at $999. Engadget notes Apple doesn’t show the setup warnings Android makers do about the fragile inner panel. Cases run $79 (two-piece) to $129 (folio with kickstand), and some MagSafe accessories overhang the bottom edge.

So who should buy it?

The reviewers, aggregated, land here:

• Buy it if you’re an early adopter who has wanted an iPad mini that fits in a pocket (MKBHD’s framing), read and watch a lot on your phone, and can absorb first-generation pricing and compromises. CNET’s reviewer is switching for good; PCMag calls it the best folding phone on sale, full stop.
• Wait if you need Face ID, a telephoto, or your apps to just work: CNN and WIRED say months, WAtoday says a full year for generation two, The New York Times/Wirecutter lands the obvious: “You don’t need me to tell you that you don’t need to spend $2,000 on a phone.”

The one-sentence synthesis of 24 reviews: Apple waited seven years, and the hardware shows it — the hinge, the crease-hiding screen, the performance, and the build are the best the category has produced — but the Duo ships with two Apple-chosen frictions (no Face ID, a two-camera system at $1,999) and one ecosystem debt (unoptimized apps) that no amount of titanium can polish away. As The Verge puts it: incomplete as a product, complete enough as an idea that you can see where things are going. And with preorders already slipped to January 2027, the market’s first verdict is that plenty of people want to go there anyway.

One coverage note: SuperSaf had not published a Duo review as of October 21–22 despite the embargo lift — when it lands, this post may be updated.
