iPhone Duo vs Galaxy Z Fold8: How Apple’s Foldable Compares

Apple has officially entered the foldable smartphone market with the iPhone Duo, its first foldable iPhone.

The device combines a 7.6-inch folding display with a 5.4-inch outer screen and introduces a redesigned iOS experience for different folded and unfolded positions.

Samsung, meanwhile, has continued developing its foldable lineup with the Galaxy Z Fold8.

Rather than comparing rumors and leaked specifications, this guide looks at the officially announced specifications and features of the two devices.

iPhone Duo vs Galaxy Z Fold8: Key Specifications

Apple’s official specifications confirm the iPhone Duo’s 7.6-inch inner display, 5.4-inch outer display, A20 Pro chip, 48MP dual-camera system and 254g weight. Samsung lists the Galaxy Z Fold8 with a 7.6-inch main display, 5.5-inch cover display, Snapdragon 8 Elite Gen 5 for Galaxy and 201g weight. Apple

Display and Foldable Design

The iPhone Duo uses two Super Retina XDR displays.

The inner display measures 7.6 inches and uses a nano-texture finish designed to reduce glare and reflections. The outer display measures 5.4 inches.

Both displays support ProMotion with adaptive refresh rates up to 120Hz, Always-On functionality and up to 3,000 nits of outdoor peak brightness. Apple

Apple has also redesigned iOS 27 around the foldable form factor. The device supports different orientations and positions, including side-by-side app use and hands-free viewing scenarios. Apple

The two companies therefore take somewhat different approaches to the foldable experience: Apple emphasises adapting iOS to the device’s different positions, while Samsung has continued developing a foldable interface around its Android and One UI ecosystem.

Design, Thickness and Weight

Physical dimensions are particularly important with foldable smartphones because the devices need to balance large screens with everyday portability.

The iPhone Duo weighs 254 grams.

Apple lists its unfolded depth at 5.2mm and folded depth at 11.3mm. The device uses a titanium foldable design and includes Ceramic Shield protection. Apple

The Galaxy Z Fold8 weighs 201 grams.

Samsung lists the Fold8 at 4.5mm when unfolded and 9.7mm when folded, making it lighter and thinner than the iPhone Duo based on the manufacturers’ published specifications. Samsung Global Newsroom

For buyers who carry their phone throughout the day, these differences can be more meaningful than small processor specification changes.

Cameras

Apple’s iPhone Duo uses a 48MP Dual Fusion camera system consisting of:

• 48MP Fusion Main
• 48MP Fusion Ultra Wide
• Up to 2x optical-quality zoom

It also includes a 12MP Center Stage front camera and an under-display FaceTime camera. Apple

The foldable design enables features such as Duo Preview, which allows the outer display to be used as a preview screen while taking photographs.

Samsung’s Galaxy Z Fold8 uses:

• 50MP Wide camera
• 50MP Ultra Wide camera
• 10MP cover camera
• 10MP main display camera

Samsung also highlights features such as Dual Recording and My FanCam for video creation. Samsung Global Newsroom

The megapixel count alone doesn’t determine camera quality, so buyers should consider image processing, video features, camera software and real-world testing alongside the specifications.

Performance and Software

The iPhone Duo is powered by Apple’s A20 Pro.

Apple says the chip includes a 6-core CPU, 7-core GPU and dual 16-core Neural Engine. The company also says the CPU is up to 20% faster than the A19 Pro and the GPU is up to 40% faster and more power efficient. Apple

The phone runs iOS 27, which Apple has redesigned to accommodate the foldable form factor.

The more important difference for buyers is therefore the ecosystem.

Someone already using an iPhone, Apple Watch, Mac and other Apple services may value the iOS ecosystem, while Android users may prefer the flexibility and multitasking environment of Samsung’s foldable platform.

Battery and Charging

Apple uses a dual-battery architecture inside the iPhone Duo.

Instead of publishing a battery capacity figure, Apple provides video playback measurements of:

• Up to 31 hours using the inner display
• Up to 44 hours using the outer display
• Up to 24 hours when both displays are used equally

Apple also says the device can reach up to 50% charge in around 20 minutes using wired charging under its stated conditions. Apple

Samsung lists a 4,800mAh dual battery for the Galaxy Z Fold8 and supports wired charging of up to 63% in around 30 minutes with a 45W adapter and compatible cable. Samsung Global Newsroom

Battery capacity and advertised playback figures aren’t directly comparable, so independent testing will be more useful for determining everyday endurance.

AI and On-Device Processing

AI is becoming an increasingly important part of flagship smartphones.

The iPhone Duo includes Apple’s Apple Intelligence features and a dual 16-core Neural Engine. Apple’s A20 Pro is designed to provide additional on-device AI processing capability. Apple

Samsung’s Galaxy Z Fold8 uses its processor’s CPU, GPU and NPU capabilities alongside Galaxy AI features integrated into One UI.

For buyers, the important question is not simply which phone has more AI branding.

Instead, consider which AI features are actually available in your region and language and whether they are useful for the tasks you perform.

Pricing and Availability in India

Apple’s official India pricing starts at ₹2,99,900 for the iPhone Duo.

Storage options include 256GB, 512GB, 1TB and 2TB. Apple says the phone will be available in India from October 23, 2026, with pre-orders beginning October 16. Apple Images

Because smartphone prices and promotional offers can change, buyers should check the manufacturer’s current India store price before purchasing.

Which Type of Buyer Should Consider Each?

iPhone Duo may suit you if:

• You already use Apple’s ecosystem.
• You want a foldable iPhone experience.
• You value the iOS ecosystem and Apple’s hardware-software integration.
• You want a large 7.6-inch inner display.
• You need up to 2TB of storage.
• You are comfortable with the premium price.

Galaxy Z Fold8 may suit you if:

• You prefer Android.
• You want a lighter foldable.
• You prioritise a thinner physical design.
• You want Samsung’s established foldable software environment.
• You prefer Samsung’s multitasking and Galaxy AI ecosystem.
• You want a lower physical weight for everyday carrying.

These are feature-based considerations rather than a universal ranking. The better fit depends on the software ecosystem and hardware requirements of the individual buyer.

What to Check Before Buying a Foldable Phone

Before purchasing either device, check:

1. Weight — foldables can be considerably heavier than conventional smartphones.
2. Folded thickness — important for pockets and one-handed use.
3. Inner display size — consider how much extra screen space you actually need.
4. Software multitasking — test whether your preferred apps work well on the larger display.
5. Camera requirements — compare the actual camera system rather than megapixel numbers alone.
6. Battery performance — look for independent testing.
7. Accessories — check whether cases, chargers or other accessories are included.
8. Repair and warranty coverage — particularly important with foldable hardware.
9. Storage — determine whether 256GB is sufficient or whether you need more.
10. Ecosystem compatibility — consider your existing phone, computer, wearable and other devices.

Final Takeaway

The iPhone Duo represents Apple’s entry into a smartphone category that Samsung has been developing for several generations.

Apple’s approach combines a 7.6-inch folding display, titanium construction, A20 Pro performance, iOS 27 and a 48MP dual-camera system. Samsung’s Galaxy Z Fold8 takes a different approach with a 7.6-inch main display, lighter 201g design, Snapdragon 8 Elite Gen 5 for Galaxy and One UI 9. Apple

The biggest decision isn’t simply about specifications.

For potential buyers, the important questions are which operating system they prefer, how much they value foldable multitasking, how important weight and thickness are, and whether the premium pricing fits their requirements.
