The Foldable Face-Off: Apple iPhone Duo vs. Samsung Galaxy Z Fold8

Subscribe to our Telegram channel for the latest stories and updates.

Apple has spent years avoiding foldable phones, allowing its primary rival to define the form factor for nearly a decade. Now that the Apple iPhone Duo officially exists, the obvious point of comparison is Samsung’s Galaxy Z Fold8.

Both devices operate on the same foundational premise: a conventional smartphone layout on the exterior that unfolds along a mechanical hinge to expose a much larger, tablet-like internal workspace. On paper, the macro-level specifications line up symmetrically. Both offer 7.6-inch internal flexible displays, 120Hz refresh rates, 256GB of base flash storage, and high-end silicon.

However, those technical similarities lose utility once you examine their physical dimensions, camera arrays, charging architecture, and approach to software optimisation. The Fold8 arrives considerably lighter and thinner, whereas the Duo leverages a cutting-edge 2nm system-on-a-chip (SoC), a distinct approach to its camera configuration, and Apple’s maiden attempt at adapting the iOS paradigm to a pliable canvas.

Here is how the two premium foldables compare under close scrutiny.

The Samsung Is Much Lighter

The iPhone Duo weighs in at a hefty 254g, while the Galaxy Z Fold8 drops down to a remarkably svelte 201g. That represents a 53g delta—roughly the physical weight of a standard chocolate bar. It is a significant enough difference that you will immediately notice the heft in a pocket or when holding the device open for extended reading sessions.

Samsung also claims the victory in pure thinness. The Fold8 measures a mere 9.7mm thick when folded shut and scales down to 4.5mm when fully opened. Conversely, the Duo is a thicker device at 11.3mm when closed and 5.2mm when deployed.

Apple does opt for more exotic metallurgy, wrapping the Duo in a structural titanium enclosure and hinge cover. Samsung relies primarily on an aluminum frame, though it has quietly integrated titanium reinforcement structures directly beneath the flexible internal display panel.

Both devices are engineered with an eye toward structural longevity, though their ingress protection ratings diverge. The iPhone Duo carries a formal IP68 rating, while the Fold8 secures an IP48 certification. While this technically awards Apple the higher score for fine particulate resistance, it is worth noting that these laboratory ratings measure static resistance and are not a comprehensive metric for how well either moving hinge mechanism will survive real-world dust accumulation over multiple years of use.

The Outer Screens Are Smaller Than They Look

The iPhone Duo features a 5.4-inch outer display with a 1398 × 2034 resolution. Samsung’s cover panel measures slightly larger at 5.5 inches along its rounded corners, rendering at 1972 × 1248 pixels. Both panels support variable refresh rates maxing out at 120Hz.

The real differentiator here is the physical geometry. Apple’s outer screen is notably tall and narrow, whereas Samsung has steadily pushed the Fold8 toward a wider 16:10 aspect ratio. Samsung’s design choice here feels more natural, making typing on the virtual keyboard and scrolling through standard apps significantly less cramped than on previous generations.

Both manufacturers claim their respective panels can push up to 3,000 nits of peak outdoor brightness. Apple also adds its low-reflection nano-texture finish option to the internal screen and brings its custom always-on display implementation to the outer glass. There is no clear winner on raw specifications alone; the choice comes down to whether you prefer Apple’s narrow, elongated aspect ratio or Samsung’s wider, traditional layout.

The Main Screens Are Almost The Same Size

Unfurl both handsets, and you are greeted by a 7.6-inch main display panel. The Duo’s internal OLED panel runs at a resolution of 1878 × 2670 pixels, yielding a sharp pixel density of 430ppi. Samsung’s Dynamic AMOLED 2X panel outputs at 1848 × 2448 pixels, dropping slightly behind in spatial density at 404ppi. Both refresh at up to 120Hz.

Apple’s internal panel features an optional nano-texture glass layer explicitly aimed at mitigating harsh environmental reflections. It also includes support for the Apple Pencil (USB-C model), though Apple notes that full software optimisation for stylus input will arrive via a point-update later this year.

Samsung’s internal display features its own anti-reflective chemical treatment alongside a refined structural stack meant to reduce the tactile and visual prominence of the centre crease. The screen uses a 4:3 aspect ratio, giving the unfolded Fold8 a distinctly squarer desktop environment than its predecessors.

The raw metrics favour neither device cleanly. Apple delivers a higher total pixel count and density, while Samsung provides a boxier layout that more closely mirrors the utility of a traditional small tablet.

Apple Has The Newer Chip

The iPhone Duo is powered by Apple’s brand-new A20 Pro SoC, fabricated on TSMC’s cutting-edge 2nm node. The silicon packages a six-core CPU, a seven-core GPU, and an updated dual 16-core Neural Engine. Apple claims the CPU delivers a 20 percent performance uptick over the A19 Pro, while the GPU jumps up to 40 percent faster while maintaining better thermal efficiency. Note that these metrics are relative to Apple’s older architectures—they tell us little about how the chip stacks up directly against Qualcomm’s latest silicon. Independent benchmarking will have to untangle the real-world performance differences.

The Galaxy Z Fold8 relies on Qualcomm’s custom Snapdragon 8 Elite Gen 5 for Galaxy. Samsung pairs this SoC with 12GB of RAM on the 256GB and 512GB storage SKUs, while stepping up to 16GB of RAM if you spring for the top-tier 1TB model. Apple, true to form, does not officially disclose RAM capacities on its public consumer specification sheets, though the Duo can be configured with up to 2TB of internal flash storage.

Ultimately, comparing RAM capacities or nanometer nodes across entirely different operating systems and thermal envelopes offers very little objective insight. Real-world performance will come down to how each OS manages sustained workloads and manages heat dissipation within these incredibly cramped chassis designs.

The Camera Hardware Is Closer Than You Might Expect

Compromises abound in foldable imaging systems, and neither device matches the dedicated, long-range hardware found on traditional flagship slab phones. Notably, neither phone includes a discrete, high-magnification optical telephoto camera lens.

The iPhone Duo carries two 48MP rear-facing sensors: a wide main camera and an ultrawide lens. Apple uses the high resolution of the main sensor to crop in and provide a software-assisted “2x optical-quality” telephoto toggle. The Galaxy Z Fold8 takes a similar tack, offering two rear cameras—a 50MP wide and a 50MP ultrawide—likewise leveraging pixel-cropping for its 2x zoom mode alongside a digital zoom that tops out at 10x.

The front-facing arrays diverge slightly in implementation. The Duo features a 12MP Center Stage camera on the cover display and an under-display FaceTime camera embedded into the inner screen. Samsung deploys a 10MP camera on the cover glass and a 10MP under-display camera on the interior canvas.

For mobile videographers, Samsung claims the higher marketing metric, supporting 8K video capture at up to 30fps. Apple tops out at 4K Dolby Vision recording at 60fps on its rear sensors. While a higher pixel count does not inherently equate to superior colour science or dynamic range, Samsung holds the technical edge if you absolutely require raw 8K capture.

Apple’s Battery Numbers Need Some Context

Apple declines to state the exact milliamp-hour capacity of the Duo’s internal split-battery system. Instead, internal documentation rates the device for up to 31 hours of continuous video playback on the large internal screen, or up to 44 hours using only the smaller cover display. When utilising both displays evenly under standard workloads, Apple quotes a realistic 24-hour battery endurance window.

The Fold8 packages a 4,800mAh battery cell, which Samsung officially rates for up to 26 hours of continuous video playback.

Apple and Samsung use distinct automation scripts to test battery longevity. Given the varying power draw of their displays, distinct OS architectures, and contrasting silicon efficiencies, capacity numbers alone are a poor shorthand for total runtime.

On the charging front, the comparisons are more straightforward. Apple claims the Duo can replenish from zero to 50 percent capacity in approximately 20 minutes, provided you plug it into a 60W or higher USB-PD brick. MagSafe and Qi2 wireless charging speeds top out at 25W. Samsung supports up to 45W wired charging speeds alongside traditional Qi wireless charging and reverse wireless power-sharing.

Both foldables feature a single USB-C port, but the underlying protocol support is vastly different. The iPhone Duo’s port operates on the USB 3 standard, pushing data transfers up to 10Gbps and outputting video via DisplayPort. It can easily mirror or extend the iOS UI onto an external monitor, but Apple offers no native desktop environment here.

The Fold8 supports the USB 3.2 Gen 1 standard and includes matching DisplayPort video out. Crucially, it fully supports Samsung DeX. When connected to an external display, DeX transforms the mobile operating system into a windowed, desktop-style interface. For enterprise users aiming to deploy a foldable as a highly mobile, lightweight computing station, this software layer remains a massive operational advantage over iOS.

Samsung Still Gives You A Physical SIM Option

For international travelers or corporate users who frequently hot-swap physical SIM cards, connectivity hardware matters. The iPhone Duo is entirely eSIM-only across all global markets. Samsung, meanwhile, continues to offer a physical nano-SIM slot alongside eSIM support on the Galaxy Z Fold8, with dual-SIM hardware configurations shifting depending on your local region.

Both platforms support modern wireless standards including Wi-Fi 7, Bluetooth 6, and Ultra-Wideband (UWB). Apple utilises its second-generation proprietary UWB tracking silicon, while Samsung lists standard UWB compatibility without detailing the specific generation of the hardware chip.

The AI Ideologies Diverge

The battle between Apple Intelligence and Galaxy AI highlights two completely different software design strategies for large-screen devices.

Apple takes a conservative, deeply integrated approach with Apple Intelligence on the iPhone Duo. Operating primarily via the on-device 2nm A20 Pro Neural Engine, Apple’s AI architecture focuses heavily on system-wide linguistic and contextual awareness. Features like text summarisation, tone shifting in Mail, and automated notification prioritisation are woven quietly into the fabric of the OS. The large internal canvas doesn’t introduce wild new AI tricks; rather, it gives features like the updated Siri more screen space to display contextual data overlays without fully interrupting your active workflow.

Samsung’s Galaxy AI on the Fold8 is far more expansive, aggressively forward-facing, and unashamedly reliant on hybrid cloud processing (though a settings toggle lets you lock processing strictly to the device if you value data privacy). The Fold8 takes full advantage of its boxy 7.6-inch display with productivity tools like Now Nudge and Now Brief.

If you receive a text message containing a date, Galaxy AI surfaces a contextual calendar window directly within the split-screen multitasking layout without forcing you to abandon your chat app. Furthermore, tools like Sketch to Image allow you to rough-sketch an object on the large internal display and watch the local generative model transform it into a rendered graphic—a feature that feels uniquely satisfying on a canvas of this scale, even if its day-to-day practical utility remains open to debate.

The Price Difference Is Not Small

In Malaysia, the entry-level 256GB Apple iPhone Duo demands a massive initial financial outlay of RM9,499. Samsung’s Galaxy Z Fold8 undercuts its new rival substantially, entering the local market at RM7,299 for an identical base storage configuration. While both devices represent an eye-watering capital premium compared to standard, single-screen smartphones, Samsung commands an explicit RM2,200 hardware pricing advantage in the region. This delta is further exacerbated by Samsung Malaysia’s comparatively mature and aggressive retail machinery, which routinely leverages immediate over-the-counter trade-in bonuses, targeted telco subsidies (via local carriers like Maxis and CelcomDigi), and institutional promotional discount codes that Apple rarely matches at launch.

The Verdict

THE GOOD

THE UGLY

The decision between these two top-tier foldables hinges almost entirely on platform ecosystem ties and hardware ergonomics.

You should buy the Samsung Galaxy Z Fold8 if your primary goal is pocketability and immediate productivity. Its significantly lighter, thinner footprint makes it far less exhausting to carry as a daily driver, and its mature One UI multitasking tools—combined with Samsung DeX—deliver a legitimate desktop-replacement experience that Apple’s mobile operating system simply cannot match.

You should buy the Apple iPhone Duo if you are deeply entrenched in the Apple ecosystem and have been waiting for iOS to break out of its fixed constraints. While it is undeniably a heavy, first-generation device, it rewards early adopters with industry-leading 2nm processing power, superior IP68 liquid ingress protection, and a unique anti-glare screen treatment that makes working outdoors a genuine pleasure.
