iPhone Duo vs Samsung Galaxy Z Fold8: Which Foldable Should You Buy in Singapore?

The foldable smartphone market has a major new rivalry. Apple has entered the category with the iPhone Duo , while Samsung continues its long-running foldable lineup with the Galaxy Z Fold8 .

On paper, the two phones look surprisingly similar. Both open into a 7.6-inch main display, both offer a smaller external screen for everyday use, both support refresh rates of up to 120Hz and both combine flagship performance with AI-powered software.

But once you look closer, Apple and Samsung have taken very different approaches to the foldable phone.

The iPhone Duo focuses on Apple’s first foldable iPhone experience, a short and wide design, deep integration with iOS 27, Apple Intelligence and features such as Apple Pencil support.

The Galaxy Z Fold8 takes advantage of Samsung’s years of foldable experience, delivering a significantly lighter and thinner body, Galaxy AI, Android flexibility and a form factor designed around content consumption and multitasking.

So how do these two premium foldable phones compare? Here’s our complete iPhone Duo vs Samsung Galaxy Z Fold8 comparison for Singapore buyers.

📊 iPhone Duo vs Galaxy Z Fold8: Quick Comparison

📱 Design: Two Very Different Foldable Philosophies

The iPhone Duo and Galaxy Z Fold8 both use a book-style foldable design, but they feel very different in the hand.

The iPhone Duo uses an unusually short and wide design. When closed, it measures just 84.1mm wide and features a compact 5.4-inch outer display.

Open the device and it becomes a wide 7.6-inch canvas designed for multitasking, video, games and larger app layouts.

Apple uses a titanium foldable design with a precision hinge, Ceramic Shield 2 on the front and Ceramic Shield on the rear.

Samsung takes a different approach.

The Galaxy Z Fold8 uses a more conventional phone-like shape when closed, with a 5.5-inch cover display designed for messaging, scrolling and everyday smartphone use.

When opened, it also expands into a 7.6-inch display.

🪶 Galaxy Z Fold8 Is Much Lighter

One of the biggest differences in the iPhone Duo vs Galaxy Z Fold8 comparison is surprisingly not the screen.

It is the weight.

At just 201g, the Galaxy Z Fold8 is 53g lighter than the 254g iPhone Duo.

That is a considerable difference for a device that you may carry in your pocket every day.

Samsung’s foldable is also thinner. The Galaxy Z Fold8 measures 4.5mm when unfolded and 9.7mm when folded, compared with 5.2mm and 11.3mm respectively on the iPhone Duo.

🖥️ Display: 7.6 Inches vs 7.6 Inches

This is where the iPhone Duo vs Galaxy Z Fold8 comparison becomes interesting.

Both phones offer a 7.6-inch folding main display, but the screen technology and surrounding software are different.

iPhone Duo

The iPhone Duo uses a 7.6-inch Super Retina XDR OLED folding display with a resolution of 1878 × 2670 pixels.

It supports ProMotion with adaptive refresh rates up to 120Hz, HDR, True Tone, Always-On display and up to 3,000 nits of peak outdoor brightness.

Apple has also applied a nano-texture finish to the inner display to help reduce reflections and glare.

Galaxy Z Fold8

Samsung uses a 7.6-inch Dynamic AMOLED 2X main display with a resolution of 1848 × 2448.

The display supports an adaptive refresh rate of up to 120Hz and is built around a wider 4:3-style layout designed for video, reading and side-by-side content.

On the outside, Samsung uses a slightly larger 5.5-inch cover display, compared with the iPhone Duo’s 5.4-inch outer screen.

🪟 Multitasking: iOS 27 vs Galaxy Fold Experience

Foldable phones are not only about having a larger display. The software needs to make good use of that extra space.

Apple has redesigned parts of iOS 27 specifically for the iPhone Duo.

Split View allows two supported apps to run side by side, making it possible to browse, message, work with documents or reference information without constantly moving between apps.

Samsung has several generations of experience building Android software for foldable displays.

Galaxy Z Fold8 continues that approach with layouts designed for its large inner display, side-by-side productivity, app continuity and Galaxy AI features.

The biggest difference here is ecosystem.

Users already invested in Mac, iPad, Apple Watch and other Apple devices may naturally benefit from the iPhone Duo’s integration with the Apple ecosystem.

Android users, particularly those already using Galaxy Watch, Galaxy Buds or Samsung services, may find the Galaxy Z Fold8 more familiar.

✏️ Apple Pencil vs S Pen: A Surprising Difference

Stylus support produces one of the more unexpected results in the iPhone Duo vs Galaxy Z Fold8 comparison.

The iPhone Duo supports Apple Pencil (USB-C), allowing users to write, sketch and mark up content on the larger folding display.

The Galaxy Z Fold8 does not support S Pen.

This is particularly notable because previous Samsung Fold devices established a strong connection between large foldable displays and S Pen productivity.

⚡ Performance: A20 Pro vs Snapdragon 8 Elite Gen 5 for Galaxy

The iPhone Duo and Galaxy Z Fold8 both use flagship processors, although comparing raw performance across iOS and Android is not as simple as comparing specifications.

The iPhone Duo is powered by Apple’s A20 Pro with a 6-core CPU, 7-core GPU with Neural Accelerators and a Dual 16-core Neural Engine.

Apple also uses a vapour-chamber cooling system to help maintain performance during demanding tasks.

The Galaxy Z Fold8 uses the Snapdragon 8 Elite Gen 5 for Galaxy, a customised Qualcomm processor designed for Samsung’s flagship Galaxy devices.

Samsung pairs the processor with 12GB RAM on the 256GB and 512GB variants and 16GB RAM on the 1TB model.

Both devices are built for high-end gaming, multitasking, AI processing and demanding mobile applications.

🤖 Apple Intelligence vs Galaxy AI

AI is becoming an increasingly important part of both smartphone ecosystems.

On iPhone Duo, the A20 Pro powers Apple Intelligence and the new Siri AI experience.

These tools are integrated across supported Apple apps and services, with Apple placing a strong emphasis on on-device processing and privacy.

Galaxy Z Fold8 combines Galaxy AI, Google Gemini and Samsung’s own software features.

The larger folding display also provides more screen space for AI-assisted workflows, research, translation, content creation and productivity.

Which approach feels better will largely depend on whether you prefer Apple’s ecosystem or the combination of Samsung, Android and Google services.

📸 Camera: 48MP Dual Fusion vs Dual 50MP

Neither device is trying to compete with the most camera-focused flagship phones through a huge telephoto system.

Instead, both use relatively straightforward dual-camera setups.

iPhone Duo Camera

The iPhone Duo features:

• 48MP Fusion Main
• 48MP Fusion Ultra Wide
• Optical-quality 2x option
• Up to 10x digital zoom
• 48MP macro photography

Apple’s foldable design also enables Duo Preview, allowing the person being photographed to see the framing using the outer display.

Galaxy Z Fold8 Camera

Galaxy Z Fold8 features:

• 50MP Wide Camera
• 50MP Ultra Wide Camera
• Optical-quality 2x zoom
• Up to 10x digital zoom
• 10MP Cover Camera
• 10MP Main Screen Camera

Samsung also uses its ProVisual Engine and Nightography processing to improve image and low-light video quality.

🔋 Battery and Charging

Apple and Samsung describe battery performance differently, so their official numbers should not be treated as a direct laboratory comparison.

Galaxy Z Fold8 has a 4,800mAh battery and Samsung rates it for up to 26 hours of video playback.

It supports up to 45W wired charging, 20W fast wireless charging and Wireless PowerShare.

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

Apple rates the device for up to 24 hours of typical use, up to 44 hours of video playback using the outer display and up to 31 hours using the inner display.

iPhone Duo supports fast USB-C charging, MagSafe and Qi2 wireless charging at up to 25W.

💧 Durability: IP68 vs IP48

Foldable phones contain more moving parts than conventional smartphones, making durability an important consideration.

The iPhone Duo carries an IP68 water and dust resistance rating.

Galaxy Z Fold8 carries an IP48 rating.

Samsung reinforces the Fold8 with an Armor Aluminum frame, Armor FlexHinge, Gorilla Glass Ceramic 3, Gorilla Glass Victus 2 and titanium layers underneath the folding display.

Apple’s design uses a titanium frame and hinge cover, Ceramic Shield 2 on the front and Ceramic Shield on the back.

📶 SIM Support Matters in Singapore

Another important difference for Singapore buyers choosing between the iPhone Duo and Galaxy Z Fold8 is physical SIM support.

The iPhone Duo is eSIM-only.

It supports two active eSIMs and can store multiple eSIM profiles, but there is no physical SIM card slot.

Galaxy Z Fold8 offers more flexibility with support for Nano-SIM + eSIM as well as Dual eSIM.

💾 iPhone Duo vs Galaxy Z Fold8 Storage Options

Both devices offer storage up to 1TB, while the iPhone Duo additionally provides a 2TB configuration.

Apple does not publicly list RAM capacity in the same way Samsung does, so RAM figures are intentionally not included for the iPhone Duo.

💰 iPhone Duo vs Galaxy Z Fold8 Price in Singapore

Samsung launched the Galaxy Z Fold8 in Singapore at a lower price than Apple’s iPhone Duo across every directly comparable storage capacity.

Interestingly, the launch-price difference is exactly S$601 across the 256GB, 512GB and 1TB configurations.

Galaxy Z Fold8 has already been on sale in Singapore, so current retail pricing and promotions may be lower than its original launch RRP.

MobileRelation prices may also change depending on stock, device condition, storage and device option.
