iPhone Duo vs Galaxy Z Fold 8 is a choice between two foldable phones in passport format, with an internal screen of the same diagonal of 7.6 inches. iPhone wins with IP68 dust resistance and the Apple ecosystem. 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 of Apple and Samsung, and at the end of each section, we provide a brief verdict.
One caveat: iPhone Duo will be available for sale only on October 23, so this is a comparison of manufacturer data, not a test.

Data: specyfikacja iPhone’a Duo, porównanie Galaxy Z Fold 8 i Fold 8 Ultra i informacja prasowa Samsunga
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 versus 5.2 mm.
Po lewej rozłożony iPhone Duo, po prawej Galaxy Z Fold 8. Źródła: Apple Newsroom, Samsung Newsroom
Apple wykonało obudowę z tytanu Grade 5 z lustrzanym polerem. Samsung postawił na technologię Flex Titanium, czyli tytanową warstwę pod ekranem, która ma wzmacniać panel i z czasem ograniczać widoczność zagięcia.
Werdykt: Galaxy Z Fold 8. Jest lżejszy o 53 g i cieńszy po złożeniu o 1,6 mm.
Ekrany i zagięcie
Na papierze to remis. Oba ekrany wewnętrzne mają 7,6 cala, odświeżanie do 120 Hz i jasność do 3000 nitów. iPhone ma odrobinę gęstsze piksele (430 wobec 403 ppi), ale z normalnej odległości tej różnicy nie zobaczysz.
Liczy się wykończenie. iPhone Duo ma matową powłokę nanostrukturalną, która tłumi odblaski i według Apple ogranicza widoczność linii zgięcia. Samsung stosuje wykończenie o niskim współczynniku odbicia i funkcję Vision Booster, ale nie opisuje ekranu jako matowego.
Drugą różnicą są proporcje. W Fold 8 ekran wewnętrzny ma format 4:3, bliski kwadratu, wygodny do czytania i pracy na dokumentach. Według Apple oba ekrany Duo mają te same proporcje, więc po rozłożeniu treść skaluje się proporcjonalnie, a przejście z małego ekranu na duży jest płynne.
Uwaga: część właścicieli Fold 8 zauważyła, że rogi ekranu wewnętrznego lekko się uginają pod naciskiem. Samsung w odpowiedzi dla użytkowników w Korei Południowej wyjaśnił, że to celowa strefa amortyzująca, która chroni wyświetlacz, a nie wada. Dotyczy to też Fold 8 Ultra. Relacjonuje SamMobile.
Werdykt: remis z lekką przewagą iPhone’a Duo za matowe wykończenie.
Wydajność i system: A20 Pro kontra Snapdragon
iPhone Duo dostał A20 Pro, ten sam czip co iPhone 18 Pro, z komorą parową połączoną bezpośrednio z procesorem. Samsung używa Snapdragona 8 Elite Gen 5 for Galaxy z 12 lub 16 GB RAM. To flagowe układy tej generacji, więc w codziennym użyciu żadnemu z telefonów nie zabraknie mocy. Który jest szybszy w grach, pokażą testy.
Większa różnica jest w oprogramowaniu. iOS 27 na iPhonie Duo po raz pierwszy daje Split View, czyli dwie aplikacje obok siebie. Samsung rozwija wielozadaniowość od siedmiu generacji Foldów: One UI dzieli ekran na trzy aplikacje i dodaje okna pływające.
Galaxy AI po polsku, Apple Intelligence bez polskiego
Dla polskiego użytkownika to jedna z najważniejszych różnic w tym porównaniu. Galaxy AI obsługuje język polski: działają m.in. tłumaczenie rozmów na żywo i Asystent pisania.
Apple Intelligence działa w 16 językach, wśród których polskiego nie ma. Jeśli funkcje AI są dla Ciebie ważne, Fold 8 daje dziś wyraźnie więcej.
Funkcje iOS 27, których w Polsce nie będzie
iOS 27 starts in the European Union cut down. Apple announced in June that due to the requirements of the EU Digital Markets Act (DMA), it is suspending 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 presented by Apple as the biggest advantage of the large Duo screen. On the Polish iPhone Duo, today you only get 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 versions of iOS 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 launch.
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 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 shot 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 chosen 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.
Batteri og lading
Samsung oppgir konkret: 4 800 mAh i to celler. Apple avslører ikke kapasiteten. Det er bare kjent at Duo også har to celler, en i hver halvdel, og ifølge produsenten varer den opptil 24 timer med typisk bruk.
Rask lading ifølge produsentene ser slik ut:
- iPhone Duo: 50% på omtrent 20 minutter med USB PD 60 W-lader, 50% på omtrent 30 minutter med MagSafe og 35 W-lader, trådløst på MagSafe og Qi2-ladere opptil 25 W.
- Galaxy Z Fold 8: 63% på omtrent 30 minutter med 45 W-lader og 3A-kabel, trådløst opptil 20 W (Qi), og i tillegg omvendt lading av andre enheter.
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 the guide on chargers for the Galaxy Z Fold 8 Ultra, as both Folds charge at the same power.
Verdict: undecidable, as Apple does not provide capacity. The Duo charges faster wirelessly (25 W vs. 20 W), while the Fold 8 can charge other devices.
Durability: IP68 vs IP48
Here, the iPhone has a clear advantage. IP68 class means complete dust resistance, and Apple claims that 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 has a Ceramic Shield 2 layer, which Apple claims is 3x more scratch-resistant than the previous generation. By 2026, the Duo will also get support for Apple Pencil, while Samsung has 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 zł | 8 749 zł |
| 512 GB | 10 999 zł | 9 599 zł |
| 1 TB | 12 999 zł | 11 299 zł |
| 2 TB | 15 999 zł | unavailable |
Manufacturer’s catalog 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 zł in favor of Samsung. For the price of the basic Duo, you can buy the Fold 8 with 512 GB and have 400 zł left. The Fold 8 is already on sale, while the iPhone Duo goes on pre-sale on October 16 at 14:00 and will be in stores on October 23. Only Apple offers the 2 TB version.
Before purchasing, check the SIM card. iPhone Duo does not have a tray and only supports 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, care about dust resistance, and 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 you won’t be able to move the accessory ecosystem and subscriptions.
In the iPhone Duo vs Galaxy Z Fold 8 showdown, 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 support for Apple Pencil will appear in 2026.
- Fold 8 has AI in Polish and longer support. Apple Intelligence doesn’t support Polish, and Siri AI doesn’t work in the EU at launch.
- Fold 8 is cheaper by 1,250 PLN and available immediately with a full range of accessories.
