iPhone Duo vs Galaxy Z Fold 8 is a choice between two foldable phones in a passport format, with an internal screen of the same diagonal of 7.6 inches. The iPhone wins with its IP68 dust and water resistance and the Apple ecosystem. The Samsung Galaxy Z Fold 8 is 53 g lighter, thinner, cheaper by 1,250 PLN, and has Galaxy AI in Polish.
The choice will mainly depend on the system you are already using. We compared both phones parameter by parameter based on the official specifications from Apple and Samsung, and at the end of each section, we provide a brief verdict.
One caveat: the iPhone Duo will be available for sale only on October 23, so this is a comparison of manufacturer data, not a test.

Data: iPhone Duo specifications, comparison of Galaxy Z Fold 8 and Fold 8 Ultra and Samsung press release
Appearance and format: two passports, different proportions
Both phones when folded resemble a passport, rather than a narrow bar like the Galaxy Z Fold 8 Ultra. However, the differences are noticeable in hand. The iPhone Duo is 6 mm shorter and 2 mm wider, but it has a thickness of 11.3 mm, while the Fold 8 is only 9.7 mm.
An even greater difference concerns weight. The Fold 8 weighs 201 g and according to Samsung is the lightest Fold in history. The iPhone Duo weighs 254 g, over a quarter more. When unfolded, the thickness difference decreases, but the Fold 8 is still thinner: 4.5 mm compared to 5.2 mm.

Apple has crafted the casing from Grade 5 titanium with a mirror polish. Samsung opted for Flex Titanium technology, which includes a titanium layer under the screen designed to strengthen the panel and gradually reduce the visibility of the crease over time.
Verdict: Galaxy Z Fold 8. It is lighter by 53 g and thinner when folded by 1.6 mm.
Screens and crease
On paper, it’s a draw. Both internal screens measure 7.6 inches, with a refresh rate of up to 120 Hz and brightness of up to 3000 nits. The iPhone has slightly denser pixels (430 vs. 403 ppi), but you won’t notice this difference from a normal viewing distance.
Finish matters. The iPhone Duo features a matte nanostructural coating that reduces glare and, according to Apple, minimizes the visibility of the crease line. Samsung uses a low-reflectance finish and Vision Booster feature, but does not describe the screen as matte.
The second difference is the aspect ratio. In the Fold 8, the internal screen has a 4:3 format, close to square, which is comfortable for reading and working on documents. According to Apple, both Duo screens have the same aspect ratio, so when unfolded, the content scales proportionally, and transitioning from the small screen to the large one is seamless.
Note: some Fold 8 owners have noticed that the corners of the inner screen slightly bend under pressure. Samsung explained to users in South Korea that this is a deliberate cushioning zone that protects the display, not a defect. This also applies to the Fold 8 Ultra. Reports SamMobile.
Verdict: a tie with a slight advantage for the iPhone Duo due to its matte finish.
Performance and system: A20 Pro vs Snapdragon
The iPhone Duo features the A20 Pro, the same chip as the iPhone 18 Pro, with a vapor chamber directly connected to the processor. Samsung uses the Snapdragon 8 Elite Gen 5 for Galaxy with 12 or 16 GB of RAM. These are the flagship chips of this generation, so neither phone will lack power in everyday use. Which one is faster in games will be shown in tests.
The bigger difference is in the software. iOS 27 on the iPhone Duo introduces Split View for the first time, allowing two apps side by side. Samsung has been developing multitasking for seven generations of Fold devices: One UI splits the screen into three apps and adds floating windows.
Galaxy AI in Polish, Apple Intelligence without Polish
For Polish users, this is one of the most important differences in this comparison. Galaxy AI supports the Polish language: features include live conversation translation and Writing Assistant.
Apple Intelligence operates in 16 languages, among which Polish is not included. If AI features are important to you, the Fold 8 clearly offers more today.
iOS 27 features that will not be available in Poland
iOS 27 launches in the European Union cut down. Apple announced in June that due to the requirements of the EU Digital Markets Act (DMA), it is withholding the new Siri AI in the EU. Along with it, you won’t get the new Siri app, enhanced Visual Intelligence, integrated writing tools, or Siri mode in the camera.
This is important because these features were showcased by Apple as the biggest advantage of the large Duo screen. On the Polish iPhone Duo, today you only have the foldable screen and Split View.
Updates: 7 generations at Samsung, minimum 5 years at Apple
Samsung promises for the Galaxy Z Fold 8 series seven generations of Android updates and seven years of security patches, which starting with Android 17 provides support until Android 24. Apple does not specify how many iOS versions the iPhone Duo will receive. In documents for the British regulator, it declares for iPhones a minimum of five years of security patches from the release.
In practice, iPhones usually receive updates longer than this minimum, but on paper, Samsung’s guarantee is stronger.
Verdict: performance is a draw until tests, and the software in Poland favors the Fold 8: Galaxy AI in Polish and longer declared support.
Cameras: 48 MP vs 50 MP, both without telephoto lens
The sets are almost identical. The iPhone Duo has two 48 MP cameras (main and ultra-wide), while the Fold 8 has two 50 MP cameras. Neither has a telephoto lens, but both offer 2x optical quality zoom, which is a crop from the center of the main sensor.
Both manufacturers similarly utilize the second screen. On the iPhone Duo, the Duo Preview feature shows a preview of the frame to the person being photographed. Samsung allows simultaneous recording with the front and rear cameras, with a preview on the external screen.
With the main camera of the Duo, you can record 4K Dolby Vision video at 120 fps, while the Fold 8 has the My FanCam feature, which automatically tracks a selected person and crops the recording to social media format.
Who takes better photos will only be shown by tests. The 10 MP telephoto lens with 3x zoom and the 200 MP camera have been reserved by Samsung for the Fold 8 Ultra, which we demonstrate in the comparison of the Ultra with the Galaxy Z Fold 8.
Battery and Charging
Samsung provides specifics: 4,800 mAh in two cells. Apple does not disclose capacity. It is known that the Duo also has two cells, one in each half, and according to the manufacturer, it lasts up to 24 hours of typical use.
Fast charging according to the manufacturers looks like this:
- iPhone Duo: 50% in about 20 minutes with a 60 W USB PD charger, 50% in about 30 minutes with MagSafe and a 35 W charger, wirelessly on MagSafe and Qi2 chargers up to 25 W.
- Galaxy Z Fold 8: 63% in about 30 minutes with a 45 W charger and a 3A cable, wirelessly up to 20 W (Qi), and also reverse charging for other devices.
None of them comes with a charger in the box. For the Duo, choose a USB PD wall charger with a power of at least 60 W, and for the Fold 8, a 45 W charger compatible with Samsung’s fast charging (USB PD with PPS). We described specific models in our guide on chargers for the Galaxy Z Fold 8 Ultra, as both Fold devices charge at the same power.
Verdict: inconclusive, as Apple does not provide capacity. The Duo charges faster wirelessly (25 W versus 20 W), while the Fold 8 can charge other devices.
Durability: IP68 vs IP48
Here, the iPhone has a clear advantage. IP68 rating means complete dust resistance, and Apple claims the Duo is resistant to immersion up to 6 m for 30 minutes.
The Galaxy Z Fold 8 has IP48. Samsung claims resistance to immersion up to 1.5 m in fresh water for 30 minutes, but it only partially protects against dust, as the standard covers particles larger than 1 mm. The manufacturer itself advises against using it on the beach and by the pool.
On the front, the iPhone features a Ceramic Shield 2 layer, which Apple claims is 3x more resistant to scratches than the previous generation. By 2026, the Duo will also support Apple Pencil, while Samsung dropped the S Pen stylus already in the Galaxy Z Fold 7.
Verdict: iPhone Duo. IP68 is a real advantage in a phone with a movable hinge.
Price and availability in Poland
| Memory | iPhone Duo | Galaxy Z Fold 8 |
|---|---|---|
| 256 GB | 9,999 PLN | 8,749 PLN |
| 512 GB | 10,999 PLN | 9,599 PLN |
| 1 TB | 12,999 PLN | 11,299 PLN |
| 2 TB | 15,999 PLN | unavailable |
Manufacturer’s list prices as of September 10, 2026. Samsung’s store has promotions, so the Fold 8 can be cheaper.
The difference in the base version is 1,250 PLN in favor of Samsung. For the price of the basic Duo, you can buy the Fold 8 with 512 GB and have 400 PLN left. The Fold 8 is already on sale, while the iPhone Duo goes on pre-sale on October 16 at 2:00 PM and will be in stores on October 23. Only Apple offers the version with 2 TB.
Before purchasing, check the SIM card. iPhone Duo does not have a tray and supports only eSIM. Galaxy Z Fold 8 has a nano-SIM slot and supports eSIM, with a maximum of two active lines at the same time, according to SamMobile. If you are using a physical card, ask your operator for an eSIM before switching to Duo.
Verdict: Galaxy Z Fold 8. It is cheaper in every capacity and available immediately.
Which foldable phone to choose: iPhone Duo or Galaxy Z Fold 8?
The choice is simpler than the length of the table suggests:
- Choose iPhone Duo if you have an iPhone, Mac, or Apple Watch, you care about dust resistance, and you plan to write with a stylus. However, be prepared for a higher price, greater weight, and lack of AI in Polish.
- Choose Galaxy Z Fold 8 if you use Android, want a lighter phone, AI in Polish, and richer multitasking. You save 1,250 PLN and can buy it immediately, but you have to reckon with weaker dust protection (IP48) and lack of a stylus.
- Consider another model if you care about close-ups from a distance. Neither of these foldables has a telephoto lens; for example, iPhone 18 Pro (4x) or Galaxy Z Fold 8 Ultra (3x) has one.
Switching from iOS to Android (or vice versa) is rarely worth it for a foldable phone. Apple Watch works exclusively with iPhone, iMessage and FaceTime won’t transfer to Android, and Galaxy Watch doesn’t work with iPhone. You can transfer data using the Move to iOS app or Samsung Smart Switch, but the ecosystem of accessories and subscriptions won’t carry over.
In the duel of iPhone Duo vs Galaxy Z Fold 8 there is no single winner. The key takeaways:
- The screen is a draw. Both have 7.6 inches, and the Duo stands out with a matte finish.
- Fold 8 is lighter and thinner. 201 g and 9.7 mm compared to 254 g and 11.3 mm.
- Duo is more waterproof and will get a stylus. IP68 versus IP48, and Apple Pencil support will arrive in 2026.
- Fold 8 has AI in Polish and longer support. Apple Intelligence does not support Polish, and Siri AI does not work in the EU at launch.
- Fold 8 is cheaper by 1,250 PLN and available immediately along with a full range of accessories.

Spigen Airskin Aramid MagSafe
Spigen Airskin Aramid MagSafe is a thin case made of aramid fiber with a magnetic ring. The Fold 8 does not have built-in magnets, so only with such a case can you attach it to MagSafe chargers and mounts, while the phone retains its greatest advantage, which is its low weight.
