iPhone Duo is the first foldable iPhone, known from leaks as the iPhone Fold. Apple unveiled it on September 9, 2026: the phone opens like a book, has a 7.6-inch inner display, a 5.4-inch outer display and Touch ID instead of Face ID. In Poland it costs from 9,999 PLN. Pre-orders opened on October 16 and sales start on October 23, but Apple’s online store currently delivers new orders only at the end of January 2027.
Updated October 21, 2026: we’ve added an overview of the first reviews, the delivery date for new orders, Apple Pencil support from iOS 27.2 and a comparison with the iPhone 18 Pro Max.
We waited seven years for a foldable iPhone after the debut of the first Galaxy Fold. In leaks it was also called the iPhone Ultra or iPhone 18 Ultra, and before the event we gathered all the reports in our iPhone 18 Pro launch preview. Apple has not explained where the name Duo came from.
Below you’ll find the specifications confirmed by Apple, Polish pricing, delivery times, a comparison with the iPhone 18 Pro Max and three compromises that get less attention. We covered the differences from Samsung separately in our comparison iPhone Duo vs Galaxy Z Fold 8. At the end there’s a practical section: how to charge the iPhone Duo and how to protect its displays.

When does the iPhone Duo launch in Poland and how much does it cost?
In Poland, the iPhone Duo is part of the first launch wave and costs from 9,999 PLN for the 256 GB model. Pre-orders opened on Friday, October 16 at 2:00 PM, and sales start on Friday, October 23, 2026. On that day the phone launches in more than 70 countries and regions, with 28 more following on October 30.
So Poland is in the first wave of the launch. Apple’s online store already has the iPhone Duo configurator with prices in Polish złoty.
| Storage | Price in Poland | Price in Germany | Price in the US |
|---|---|---|---|
| 256 GB | 9,999 PLN | 2,299 EUR | 1,999 USD |
| 512 GB | 10,999 PLN | 2,549 EUR | 2,199 USD |
| 1 TB | 12,999 PLN | 3,049 EUR | 2,599 USD |
| 2 TB | 15,999 PLN | 3,799 EUR | 3,199 USD |
Leaks about the iPhone Fold pointed to a price of around $2,000, and they turned out to be right. The Polish price includes 23% VAT and the German one 19% VAT, while the US price is quoted before tax, which explains much of the difference after conversion. The 2 TB model costs 15,999 PLN, 5,700 PLN more than the iPhone 17 Pro Max with the same storage in Apple’s August price list.
When will the iPhone Duo be delivered? Delivery times for new orders
The few who ordered in the first minutes of pre-orders will get the phone on launch day. After that, delivery estimates slipped quickly: according to MacRumors, less than half an hour after pre-orders opened, they had moved to the end of January in most countries. Bloomberg’s Mark Gurman writes about “severe supply constraints” caused by production difficulties.
Apple’s online store for Poland currently shows (as of October 21, 2026) delivery of new orders at the end of January 2027, for all storage options and both colors. The dates keep changing: 9to5Mac reports on orders whose delivery Apple has moved up, so check the current date in the Apple Store configurator before you buy.
What to have ready before you order:
- An Apple Account signed in to the Apple Store online or the Apple Store app, with a saved delivery address and payment method.
- Your chosen storage and color. The options are 256 GB, 512 GB, 1 TB and 2 TB, in Star White or Night Sky.
- An eSIM from your carrier. The Duo has no SIM tray, so check whether your carrier offers eSIM and how to transfer your number to it.
- A charger and a case. There’s no power adapter in the box, and for the fastest charging Apple requires a 60 W charger. We cover cases and screen protectors below.
iPhone Duo dimensions: folded and unfolded
Folded, the iPhone Duo is the size of a passport, and unfolded it is thinner than any previous iPhone. According to Apple’s specifications:
| Specification | iPhone Duo |
|---|---|
| Dimensions folded | 117.8 × 84.1 × 11.3 mm |
| Dimensions unfolded | 117.8 × 164.6 × 5.2 mm |
| Weight | 254 g |
| Outer display | 5.4 inches |
| Inner display | 7.6 inches |
For comparison, according to 9to5Google the Galaxy Z Fold 8 weighs 201 g and is 9.7 mm thick when folded. The Duo is therefore noticeably heavier and thicker, which we discuss in more detail in the section on compromises.
Two displays and a hinge: how the foldable iPhone works
The iPhone Duo opens like a book, just like the Galaxy Z Fold. Folded, it’s the size of a passport: the 5.4-inch outer display offers 90% of the screen area of the iPhone 18 Pro. Open it and you get 7.6 inches, a display that Apple says is 50% larger than the one on the iPhone 18 Pro Max.
According to Apple, both displays have the same aspect ratio, so content scales proportionally and switching from the small screen to the large one is seamless. On top of that there’s ProMotion up to 120 Hz, Always-On and up to 3000 nits of brightness in sunlight. Both displays also support the Apple Pencil (USB-C), more on that below.
Display crease and matte finish
The inner display has a nano-texture finish, the matte surface known from the MacBook Pro and iPad Pro. It reduces glare and, according to Apple, makes the crease less visible. The display is protected by a polymer layer that Apple says is up to 40% stiffer than the materials used in the industry so far.
The panel is sandwiched between layers of durable glass, bonded so that they slide against each other like the pages of a book. A titanium plate reinforces the whole assembly from underneath. The hinge is made of more than 100 parts and, together with a built-in magnet array, gives a secure, satisfying close.

iOS 27 on a foldable display
The system has a dedicated layout for the iPhone Duo. The Dock and navigation buttons move to the side, and the Dynamic Island appears vertically along the edge. When unfolded, you see two Home Screen pages, with Today widgets on the left.
The biggest new feature is Split View: two apps open side by side. No previous iPhone could do this, and Apple didn’t show this mode at the June iOS 27 presentation at WWDC 2026. Placed on a table, the Duo switches to StandBy on either display, even without a charger.
Netflix, Zoom and Slack already have versions optimized for the large display.
Apple Pencil on the iPhone Duo: which stylus and from when
Apple had promised stylus support “later this year”, but it’s arriving sooner. MacRumors and 9to5Mac confirmed on October 21 that the Apple Pencil works with the iPhone Duo starting with iOS 27.2: in the RC test build, the stylus draws, takes notes and scrolls in supported apps on both displays. According to 9to5Mac, the public release of iOS 27.2 is expected around October 26.
Only the Apple Pencil (USB-C) works, and it costs 399 PLN in Apple’s online store. The Apple Pencil Pro and the Apple Pencil (2nd generation) don’t work with the Duo, so if you have one of them for your iPad, you’ll need the USB-C model for the foldable iPhone. Apple lists only this one stylus, so don’t assume that third-party styluses will work.
iPhone Duo cameras: two 48 MP lenses, no telephoto
On the back there are two cameras: a 48 MP Fusion main camera (f/1.6, sensor-shift stabilization) and a 48 MP Fusion ultra wide (120°, macro), the same as in the iPhone 18 Pro. Instead of a telephoto lens you get 2x optical-quality zoom: the camera crops the center of the 48 MP sensor and saves a 12 MP photo.
The main camera records 4K Dolby Vision video at 120 fps. On the front there are two cameras: a 12 MP Center Stage camera in the outer display and a FaceTime camera hidden under the inner display.

The two displays enable features that no other iPhone has:
- Duo Preview: the person being photographed sees the frame on the outer display and can adjust their pose.
- Selfies with the rear cameras: with a preview on the outer display, at a higher resolution than with the front camera.
- Smart shutter: an AI model takes the photo automatically when it detects that you’re posing.
- Animation for kids: Peanuts characters appear on the outer display to draw a little one’s gaze toward the lens.
- Duo FaceTime: a second person joins the call via the outer display.
Performance and battery life of the foldable iPhone
The Duo has the same A20 Pro chip as the iPhone 18 Pro, but it is cooled by a vapor chamber connected directly to the processor. According to Apple, this gives up to 35% higher sustained performance than the iPhone 17 Pro. The point of reference is last year’s model, not the iPhone 18 Pro with the same chip.
The gain should be noticeable in games and during long sessions with two apps.
Each half of the body houses a separate battery, and the two work as one. Apple doesn’t give the capacity in mAh, only battery life figures:
| Scenario | Battery life according to Apple |
|---|---|
| Typical use | up to 24 h |
| Video on the outer display | up to 44 h |
| Video on the inner display | up to 31 h |
| Streaming on the outer display | up to 37 h |
| Streaming on the inner display | up to 26 h |
Three compromises of the foldable iPhone
The specifications already reveal three weaker points of the Duo, and the first reviews confirm them. Check them before you order.
1. It’s the heaviest iPhone ever. It weighs 254 g and is 11.3 mm thick when folded. Even the iPhone 18 Pro Max weighs 249 g. According to 9to5Google’s comparison, the Galaxy Z Fold 8 weighs 201 g at 9.7 mm, and the Pixel 11 Pro Fold 239 g at 10.1 mm.
The Duo only becomes the thinnest iPhone ever when unfolded: 5.2 mm.
2. No Face ID and no telephoto lens. Apple is bringing back Touch ID in the side button, which works with the phone open or closed. You can also unlock the Duo with an Apple Watch. If you often shoot from a distance, the iPhone 18 Pro with its 4x telephoto will do a better job.
3. eSIM only and no Apple Intelligence in Polish. The Duo has no tray for a physical SIM card and supports eSIM only, with up to two active numbers at the same time. Apple Intelligence works in 16 languages, and Polish isn’t one of them.
The new Siri AI has been available as a beta in English since September 14, but according to Apple not yet in the EU, which means not in Poland either.
You also won’t be able to use the new iPhone Handoff feature (one number on two iPhones) right away. At launch it only works on T-Mobile in the US and Telekom in Germany.
What reviewers say about the iPhone Duo
The first iPhone Duo reviews were published on October 21, 2026, two days before sales start, after roughly a week of testing. Most scores are high, from 7/10 at The Verge and Wired to 4.5/5 at Tom’s Guide, TechRadar and PCMag. Reviewers agree in praising the matte display, the hinge and the build quality, but they are just as unanimous that this is still a first-generation product: heavy, without Face ID or a telephoto lens, and with many apps not yet adapted to the new displays.
Most often praised:
- The matte inner display. The nano-texture finish reduces reflections and hides the crease. You see it mainly at an angle and in certain lighting conditions, and you can feel it with your finger.
- Hinge and build quality. The hinge holds the phone at almost any angle, and the titanium frame and IP68 rating set the Duo apart from other foldables. Joanna Stern had a machine fold her unit more than 32 thousand times and felt no change in how the hinge works (MacRumors report).
- Performance and two apps side by side. According to Tom’s Guide and Gizmodo, the Duo is almost as fast as the iPhone 18 Pro. Reviewers find Split View intuitive, and Apple’s own apps make use of the large display right away.
- Battery. In most tests it lasts a day of typical use. In Tom’s Guide’s test (web browsing over 5G) the Duo lasted 13 hours 20 minutes, more than 3 hours longer than the Galaxy Z Fold 8, but less than the iPhone 18 Pro Max (17 hours 31 minutes).
Most often criticized:
- Apps that aren’t adapted. This is the most common complaint. Older apps appear in a small window with black bars or with an empty strip on the right. Full support requires developers to rebuild their apps with the iOS 27.1 SDK, and updated apps were still arriving during testing.
- Weight and thickness. At 254 g it’s heavier than the iPhone 18 Pro Max, while the Galaxy Z Fold 8 weighs 201 g. Wired, Gizmodo and Spider’s Web write about a tired hand and a weighed-down pocket.
- No Face ID. Touch ID in the side button works well, but reviewers describe instinctively waiting for the phone to unlock on its own. Unlocking with an Apple Watch helps.
- Cameras weaker than on the Pro models. There’s no telephoto lens and no ProRes or Log recording, and in low light the photos fall behind the iPhone 18 Pro. The camera under the inner display (about 4 MP according to tests) is good enough for video calls, but not for photos.
- Limited multitasking. Only two apps fit on the screen, in a fixed half-and-half split, and in portrait you can only pin a video above another app. The Duo runs iOS 27, not iPadOS, so it can’t use iPad apps. The controls are on the right side, which makes the phone harder to use for left-handed people.
- Heat and the matte display. The Verge and Wired noticed that the phone can get warm, according to The Verge especially during longer camera use. The matte finish also produces slightly paler colors and shallower blacks than a glossy OLED.
Reviewers couldn’t test Apple Pencil support yet, because it only arrives with iOS 27.2. Wired and Engadget, however, expect the matte display surface to work well for writing and drawing. The price comes up less often as a complaint, since competing foldables are similarly expensive, but most reviewers stress that this isn’t a phone for everyone.
| Outlet | Verdict | Rating |
|---|---|---|
| The Verge | Expensive, full of compromises and at times frustrating, but a lot of fun for early adopters | 7/10 |
| Engadget | “A first-class foldable”, with weight, price and unadapted apps as the downsides | 8.8/10 |
| CNET | Apple got its first foldable right, and the flaws don’t rule out buying it (Editors’ Choice award) | 8.7/10 |
| Tom’s Guide | “The best designed foldable phone I’ve ever tested”, though the lack of a telephoto lens is disappointing (Editor’s Choice) | 4.5/5 |
| TechRadar | A polished foldable worth the wait for Apple fans, but the Galaxy Z Fold 8 remains a strong alternative | 4.5/5 |
| PCMag | The best foldable phone on the market for hardware, performance and battery life (Editors’ Choice) | 4.5/5 |
| Gizmodo | Worth the wait, but very expensive and heavy | 4/5 |
| Wired | A surprisingly good first foldable, but it’s worth waiting a few months for apps to be optimized | 7/10 |
| 9to5Mac | The iPhone’s future is foldable, but for most people a regular iPhone remains the more sensible buy | no score |
| MKBHD (video) | “Very polished around the edges, but kind of rough in the middle”, with apps as the biggest drawback | no score |
| Spider’s Web | Became the author’s favorite phone within a week, despite the annoyance of no Face ID, the weight and a weaker camera | no score |
| iMagazine | “The best foldable smartphone I’ve used so far”, despite compromises in the cameras and no Face ID | no score |
As of October 21, 2026. Ratings are given on each outlet’s own scale. Quotes from Polish reviews translated by the editors.
iPhone Duo or iPhone 18 Pro Max?
The largest of the classic iPhones is the natural alternative to the Duo: the same chip, a similar weight and a big screen without a hinge. In every storage tier the Duo costs 3,200 PLN more. Below are the figures from Apple’s websites.
| Specification | iPhone Duo | iPhone 18 Pro Max |
|---|---|---|
| Price in Poland (256 GB) | 9,999 PLN | 6,799 PLN |
| Price in Poland (2 TB) | 15,999 PLN | 12,799 PLN |
| Display | 7.6″ inner (430 ppi) and 5.4″ outer (460 ppi) | 6.9″ (460 ppi) |
| Dimensions | 117.8 × 84.1 × 11.3 mm folded, 5.2 mm thick unfolded | 163.4 × 78.0 × 8.75 mm |
| Weight | 254 g | 249 g |
| Build | titanium frame and hinge cover | aluminum unibody design |
| Chip | A20 Pro | A20 Pro |
| Rear cameras | 48 MP main and 48 MP ultra wide, 2x optical-quality zoom | 48 MP main, 48 MP ultra wide and 48 MP 4x telephoto, up to 8x optical-quality zoom |

| Colors | Star White, Night Sky | Black, Silver, Glacier Blue, Burgundy |
| Delivery of new orders (Apple Store, October 21, 2026) | end of January 2027 | 2–3 weeks (256 GB) |
Data: iPhone Duo specifications and iPhone 18 Pro Max specifications on Apple’s websites; prices and delivery times from the Apple Store.
For the extra 3,200 PLN you mainly get a 7.6-inch display with Split View and stylus support. The 18 Pro Max wins on almost everything else: it has a telephoto lens and Face ID, lasts longer on a charge, charges faster and takes a physical SIM card. The weight is almost the same, but the folded Duo is shorter and more than 2.5 mm thicker, so it sits differently in your pocket.
If you don’t need a large screen for working with two apps, the 18 Pro Max gives you more for less, and without waiting until the end of January. We’ve collected the prices of all 18 Pro and 18 Pro Max versions in our iPhone 18 Pro price list for Poland.
Cases and screen protection for the iPhone Duo
Apple showed two of its own cases right away. The iPhone Duo Case consists of two parts, one for each half, and costs 399 PLN. The iPhone Duo Folio has a stand that lets you prop the phone up at various angles and costs 629 PLN. Both are already available in the Apple Store.

A case for a foldable iPhone is usually two separate shells, because it has to leave the hinge free to move. No iPhone 17 or 18 case will fit.
Screen protection on a foldable follows its own rules, which we already covered in our guide to glass and film screen protectors for the Galaxy Z Fold 8:
- Outer display: tempered or hybrid glass, just like on a regular iPhone.
- Inner display: flexible film only, because rigid glass won’t survive the folding.
- Don’t remove the factory layer on the inner display: it’s part of the display, not a shipping film.
- Matte effect: a glossy film will cover the nano-texture finish, so choose a matte film for the Duo.
Our iPhone Duo cases category already includes models from Spigen, UAG, PITAKA, Mercury and PanzerGlass, most of them with MagSafe magnets. We compared them in our iPhone Duo case ranking, split into models with and without hinge protection. You’ll find screen protector films and glass in the iPhone Duo accessories category.
How to charge the iPhone Duo: chargers and power banks
No need to wait here. There’s no wall charger in the box, and the iPhone Duo has specific requirements. Apple gives two figures:
- 50% in about 20 minutes with a USB PD wall charger rated at 60 W or higher and a USB-C cable that supports 60 W,
- 50% in about 30 minutes with a MagSafe charger connected to a wall charger of 35 W or more.
Wireless charging works with MagSafe and Qi2 at up to 25 W. Qi2 15 W chargers should also work, just more slowly. A 20 W wall charger from the iPhone 12 era will do as well, but charging will take longer than Apple states.
We chose the chargers below based on the specifications Apple provides, not on our own tests with this phone. More models, split into wall chargers, MagSafe chargers and power banks, are covered in our ranking which charger to get for the iPhone Duo.
UGREEN Nexode Air 65W


UGREEN Nexode Air 65W exceeds the 60 W threshold Apple requires for the fastest charging. It has two USB-C ports and one USB-A port, and thanks to GaN (gallium nitride) technology it’s compact despite its high output. You get the full 65 W with a single device connected. When you charge two at once, the power is split between the ports and the Duo may not get the required 60 W.
Satechi 3-in-1 Qi2 25W


Satechi 3-in-1 Qi2 25W charges your phone at the full Qi2 25 W, and a watch and earbuds along with it. The foldable design takes up little space when folded, so it also works well for travel.
Tech-Protect PB40 LifeMag 10,000 mAh


Tech-Protect PB40 LifeMag is a magnetic power bank using the Qi2.2 standard, which means 25 W wireless charging. You snap it onto the back of the phone and charge on the go without a cable. With a phone that weighs 254 g, you’ll definitely feel any power bank in your hand.
If you prefer a simple desk charger, Tech-Protect A54 MagSafe 25W Qi2.2 delivers the same power in a single charging puck.
[hs_products ids=”76151,135816,141166,141896″ cols=”4″ title=”Chargers for the iPhone Duo”]
You’ll find more models in the wireless chargers and MagSafe accessories categories.
Is the iPhone Duo worth buying?
It depends on what you use your phone for:
- Buy it if you want a large screen for movies, reading and working with two apps, and you don’t plan to leave the Apple ecosystem.
- Choose the iPhone 18 Pro if a telephoto lens, Face ID and a lighter body matter to you. It’s also significantly cheaper.
- Consider the Galaxy Z Fold 8 if you use Android and weight and price matter more to you than water resistance.
Also keep in mind that this is a first-generation device. Apple hasn’t said how many open-and-close cycles the hinge is designed for, and in new device categories, first-generation weaknesses are usually only fixed by the second generation.
Summary
The iPhone Duo is the first foldable iPhone and also the heaviest and most expensive iPhone Apple has ever released. The key facts:
- Poland is in the first wave. Sales from October 23, price from 9,999 PLN, but new orders won’t arrive until the end of January 2027.
- Two displays with the same aspect ratio. 5.4 inches folded, 7.6 inches unfolded, with a matte finish, Split View and Apple Pencil (USB-C) support from iOS 27.2.
- The compromises are real. 254 g, 11.3 mm folded, no Face ID or telephoto lens, eSIM only, and Siri AI isn’t available in the EU at launch.
- Its edge over Samsung is IP68 and the ecosystem. The Galaxy Z Fold 8, on the other hand, is lighter and cheaper.
- You can buy chargers today. A 60 W wall charger and a 25 W Qi2 charger will make full use of what the Duo can do.
It’s worth ordering a case together with the phone, and before it arrives, check that your wall charger delivers at least 60 W. A weaker one will still charge the phone, just more slowly.
FAQ: common questions about the iPhone Duo
When will the foldable iPhone Duo be available in Poland?
Sales in Poland start on Friday, October 23, 2026, and pre-orders opened on October 16. Apple’s online store currently delivers new orders at the end of January 2027 (as of October 21, 2026), and delivery dates may change.

Are the iPhone Fold, iPhone 18 Ultra and iPhone Duo the same phone?
Yes. iPhone Fold, iPhone 18 Fold, iPhone Ultra and iPhone 18 Ultra are names from leaks; the official name of the foldable iPhone is iPhone Duo. Apple did not show the standard iPhone 18 at its September event, and it is not part of the current lineup.
Does the iPhone Duo have Face ID?
No. The foldable iPhone has Touch ID in the side button, which works with the phone open or closed. You can also unlock it with an Apple Watch.
Can the iPhone Duo split the screen between two apps?
Yes. Split View opens two apps side by side on the inner display, or even two windows of the same app, such as Safari. It’s the first iPhone with this feature.
Can I put two SIM cards in the iPhone Duo?
You can’t insert a physical card at all. The iPhone Duo supports Dual eSIM only, meaning two active numbers in digital form, so check whether your carrier offers eSIM before you buy.
Does the iPhone Duo work with the Apple Pencil?
Yes, from iOS 27.2 and only with the Apple Pencil (USB-C). The stylus works on both displays. The Apple Pencil Pro and the Apple Pencil (2nd generation) are not compatible with the iPhone Duo.
Can I put a tempered glass protector on the iPhone Duo’s inner display?
No. Only a flexible film is suitable for the inner display, because rigid glass won’t survive the folding. Use tempered glass on the outer display only.
Is the iPhone Duo worth buying? What reviewers say
According to the first reviews, yes, if you want a large screen for reading, movies and working with two apps. Reviewers praise the matte display, which almost hides the crease, the hinge and the performance, and criticize the 254 g weight, the lack of Face ID and a telephoto lens, and the many apps that still aren’t adapted. Scores range from 7/10 (The Verge, Wired) to 4.5/5 (Tom’s Guide, TechRadar, PCMag).
