As of September 20, 2026, Apple’s first foldable is officially called iPhone Duo, while Samsung’s current standard book-style foldable is the Galaxy Z Fold8. I’ll compare the iPhone Duo against the Z Fold8 rather than the older Fold7.
iPhone Duo vs Samsung Galaxy Z Fold8 — Full Detailed Comparison
1. Design and overall concept
iPhone Duo
The iPhone Duo is Apple's first foldable iPhone. It uses a book-style folding design: the phone closes into a compact smartphone and opens into a much larger display.
Apple uses a titanium frame and hinge cover, with Ceramic Shield 2 on the front and a Ceramic Shield back. When open, the device is only 5.2 mm thick and weighs 254 grams.
The design is particularly interesting because Apple has tried to make the two displays feel like part of one continuous experience. Both displays have the same general aspect-ratio philosophy, so applications and content can transition between them more naturally.
Galaxy Z Fold8
Samsung's Z Fold8 is also a book-style foldable, but Samsung has been developing this form factor for several generations.
The Fold8 is dramatically lighter at 201 grams, compared with the Duo's 254 grams. Samsung says it is its lightest Galaxy Z Fold yet and measures about 4.5 mm when unfolded and 9.7 mm when folded.
Important difference: the iPhone Duo emphasizes Apple's premium titanium construction, while Samsung puts considerable emphasis on making the Fold8 thinner and lighter.
2. Outer display
iPhone Duo
The iPhone Duo has a 5.4-inch outer OLED display.
It has:
•Super Retina XDR
•ProMotion up to 120Hz
•Always-On display
•Dynamic Island
•HDR
•3,000-nit peak outdoor brightness
•1,398 × 2,034 resolution
•460 ppi
Apple designed this screen to be useful for one-handed operation while the phone is closed.
The 5.4-inch screen is considerably smaller than what Samsung provides.
Galaxy Z Fold8
Samsung gives the Fold8 a 5.5-inch cover display with a 10:16 aspect ratio. Samsung specifically redesigned the proportions to make the cover display more comfortable for scrolling and everyday tasks.
So the Samsung display is slightly larger, but the bigger difference is the shape.
For one-handed everyday use: both are designed to be usable without opening the phone.
3. Main folding display
This is where the phones become particularly interesting.
iPhone Duo
The iPhone Duo has a 7.6-inch folding OLED display.
It provides:
•7.6-inch Super Retina XDR
•1,878 × 2,670 resolution
•430 ppi
•ProMotion up to 120Hz
•HDR
•Always-On
•3,000-nit peak outdoor brightness
•Nano-texture finish
•Anti-reflective properties
The nano-texture finish is one of Apple's more unusual choices. Apple says it reduces glare and reflections and helps minimize the visual prominence of the fold.
Galaxy Z Fold8
The standard Galaxy Z Fold8 also has a 7.6-inch main display with a 4:3 aspect ratio. Samsung designed it around movies, games, reading and multitasking.
Samsung also emphasizes its anti-reflection technology and redesigned foldable structure.
The practical difference
The two phones are surprisingly close in display size.
The bigger distinction is the software and aspect ratio philosophy.
Apple wants the Duo to behave like a very large iPhone.
Samsung wants the Fold8 to behave more like a phone + mini tablet/computer.
4. Display brightness and outdoor visibility
Both phones are extremely bright.
Apple lists up to 3,000 nits peak outdoor brightness for the Duo.
Samsung also advertises 3,000 nits for the Fold8's displays.
Therefore, on paper, neither has an obvious brightness advantage.
The more interesting difference is Apple's nano-texture inner screen, while Samsung uses an anti-reflective main display.
Both approaches are intended to improve visibility in bright environments.
5. Fold crease
Foldable displays inevitably have a folding area.
Apple has made the crease a major engineering focus. Its nano-texture display and hinge design are intended to reduce the visual impact of the crease. Apple also describes its precision hinge as designed for a smooth and stable folding experience.
Samsung has also worked extensively on its crease and hinge. The Z Fold8 uses Samsung's newer Flex Titanium display structure and redesigned hinge system, with the company emphasizing reduced crease visibilitly.
In real-world use, the exact difference is something I'd want to evaluate through long-term testing rather than rely solely on manufacturer specifications.
6. Processor and performance
iPhone Duo — A20 Pro
The iPhone Duo uses Apple's A20 Pro chip.
It has:
•6-core CPU
•7-core GPU
•Neural Accelerators
•Dual 16-core Neural Engine
•Hardware-accelerated ray tracing
•2-nanometer manufacturing
•50% more memory bandwidth than A19 Pro
Apple claims the CPU is up to 20% faster than A19 Pro, while the GPU is up to 40% faster and more power efficient. Apple also claims up to 35% better sustained performance than iPhone 17 Pro.
The Duo additionally uses a custom vapor chamber to manage heat during demanding workloads.
This is important because foldables have relatively little internal space for cooling.
Galaxy Z Fold8 — Snapdragon 8 Elite Gen 5 for Galaxy
The Fold8 uses Qualcomm's Snapdragon 8 Elite Gen 5 for Galaxy.
Samsung specifically customizes the processor for Galaxy devices, with a powerful CPU, GPU and NPU for AI, gaming and multitasking.
Performance comparison
Both are flagship-level processors.
The important difference isn't simply benchmark numbers.
The iPhone Duo is designed around:
Apple silicon + iOS + Apple Intelligence
Samsung is designed around:
Snapdragon + Android + One UI + Galaxy AI
For heavy gaming, video editing and demanding applications, both should be exceptionally powerful.
7. Multitasking
This is one of Samsung's traditional strengths.
The large Fold8 display is specifically designed around multitasking, and Samsung's software allows several applications to operate simultaneously.
You can use combinations such as:
•YouTube + WhatsApp
•Browser + Notes
•Email + documents
•Video + messaging
•Multiple apps simultaneously
Samsung's Fold ecosystem is particularly mature in this area.
iPhone Duo
Apple is bringing a much more sophisticated multitasking experience to iOS on the Duo, taking advantage of the 7.6-inch display.
Apple has redesigned parts of iOS for the foldable format and positions the larger screen as a workspace for multitasking.
However, Samsung has had several generations to refine foldable multitasking.
So the important distinction is:
Samsung = more established foldable multitasking philosophy
Apple = new foldable experience deeply integrated into iOS
8. Camera system
This is another major difference.
iPhone Duo
Apple gives the Duo a 48MP Dual Fusion camera system.
It includes:
•48MP Fusion Main
•48MP Fusion Ultra Wide
•2x optical-quality telephoto capability
•Macro photography
•Night mode
•Photonic Engine
•Deep Fusion
•Smart HDR
•4K Dolby Vision video
•Cinematic video
•Advanced stabilization
Apple's main camera can provide a 2x optical-quality crop, but this isn't the same thing as having a dedicated long-range telephoto lens.
Apple also puts considerable emphasis on video.
9. Galaxy Z Fold8 cameras
The standard Z Fold8 has a dual 50MP rear-camera system according to Samsung's official specifications:
•50MP Wide
•50MP Ultra Wide
Samsung also advertises up to 10x digital zoom.
This is important because Samsung has changed the camera philosophy of the standard Fold8.
The Fold8 is more focused on a lighter, thinner body rather than packing the maximum possible camera hardware.
Samsung also offers the Galaxy Z Fold8 Ultra, which is a different model and adds a 200MP wide camera and 10MP telephoto camera with 3x optical zoom.
So if you're comparing the Duo specifically with the standard Fold8, don't confuse it with the Fold8 Ultra.
10. Video recording
Apple traditionally puts enormous emphasis on smartphone video, and the Duo continues that approach.
The Duo supports:
•4K Dolby Vision
•24/25/30/60fps
•Cinematic mode
•Stabilization
•Spatial audio
•Audio Mix
•Slow motion
•Time-lapse
It also introduces unusual foldable-oriented shooting features.
For someone who frequently records:
•YouTube videos
•Instagram Reels
•travel videos
•family videos
•cinematic clips
the iPhone's video ecosystem is particularly significant.
11. Front camera
The iPhone Duo uses an under-display FaceTime camera on the inner screen and supports Centre Stage features.
That means Apple can maintain a much cleaner uninterrupted inner display.
Samsung also provides front-facing cameras designed for the foldable form factor.
The important difference is Apple's emphasis on hiding the internal camera beneath the display so the 7.6-inch screen feels more seamless.
12. Battery
iPhone Duo
Apple doesn't publicly emphasize battery capacity in mAh in the same way Android manufacturers do.
Instead, Apple provides usage figures.
The Duo offers up to:
24 hours of typical usage
and:
up to 31 hours of video playback using the inner display
and:
up to 44 hours using the outer display.
It uses a dual-battery system, with a battery on each side of the folding phone.
Galaxy Z Fold8
Samsung gives the Fold8 a 4,800mAh battery and advertises up to 26 hours of video playback.
Important point
Don't directly compare "4,800mAh" with Apple's battery figures.
Different processors, displays, software and battery architectures mean mAh alone doesn't tell you which phone will actually last longer.
13. Charging
This is an area where the Duo has a significant specification advantage.
Apple says the Duo can reach approximately:
50% in around 20 minutes using a 60W-capable adapter or higher.
With MagSafe, Apple says approximately:
50% in around 30 minutes using a 35W adapter or higher.
Samsung's Fold8 uses Samsung's fast-charging system, while Apple's wired charging figures are notably aggressive for a foldable.
14. Water and dust resistance
This is very important for foldables.
The iPhone Duo carries an IP68 rating, with Apple specifying resistance at a maximum depth of 6 metres for up to 30 minutes under IEC 60529.
Samsung also has extensive durability engineering for the Fold8, including Armor Aluminum, Gorilla Glass Ceramic 3/Victus 2 and its Flex Titanium display structure.
The overall message is that Samsung and Apple are treating their latest foldables as everyday smartphones rather than delicate experimental devices.
15. Durability
Apple's approach is extremely premium.
The Duo uses:
•Grade 5 titanium frame
•Titanium hinge cover
•Ceramic Shield 2
•Ceramic Shield back
•Reinforced folding structure
•Precision hinge
Apple specifically highlights long-term hinge durability.
Samsung uses:
•Armor Aluminum
•Gorilla Glass Ceramic 3
•Gorilla Glass Victus 2
•Titanium-based internal display structure
•redesigned FlexHinge
Samsung says the new structure improves durability while reducing weight. �

Apple is also introducing a significantly more capable Siri AI experience.
Galaxy Z Fold8
Samsung integrates Galaxy AI into the Fold8 and uses the Snapdragon processor's NPU for AI workloads.
Samsung's approach is particularly focused on AI features that interact with productivity, communication, content and the large foldable screen.
The two companies are taking different approaches to AI rather than simply copying each other.
18. Stylus support
This is a particularly interesting difference.
The iPhone Duo will support Apple Pencil with USB-C, according to Apple, with support coming later in 2026.
That makes the Duo considerably more interesting for:
•note-taking
•sketching
•PDF annotation
•document editing
•creative work
Samsung's Fold family has historically been associated with S Pen functionality, although support depends on the particular Fold model and generation.
19. Storage
iPhone Duo
Apple offers:
•256GB
•512GB
•1TB
•2TB
The 2TB option is particularly notable for people who record a lot of high-resolution video.
Galaxy Z Fold8
Samsung offers:
•256GB

Neither provides a microSD expansion slot.
20. Weight
This is one of the clearest hardware differences.
iPhone Duo: 254g
Galaxy Z Fold8: 201g
That's a 53g difference.
For a foldable phone that you carry all day, 53g is significant.
The Fold8 is therefore substantially lighter than the Duo.
21. Thickness
iPhone Duo:
5.2mm unfolded
Samsung Z Fold8:
4.5mm unfolded
So Samsung has made the Fold8 approximately 0.7mm thinner when open.
Folded, Samsung lists approximately 9.7mm, while Apple's Duo is approximately 11.3mm folded.
This is a noticeable engineering achievement for Samsung.
22. Ecosystem
This may be more important than specifications.
If you already use Apple products
The Duo fits naturally into:
