After years of speculation, leaks, and endless anticipation, Apple has finally entered the foldable arena with its first folding phone, the iPhone Duo. The device adopts a familiar short and wide form factor that has been tried and tested by several Android manufacturers, most notably Samsung with its Galaxy Z Fold8. This head-to-head comparison breaks down the key specifications to see how Apple’s debut foldable stacks up against Samsung’s established champion.
Size and Dimensions
When it comes to foldables, size matters—both in terms of pocketability and usability. The iPhone Duo measures 155.2 x 129.8 x 6.4 mm when unfolded, and 155.2 x 67.3 x 13.2 mm when folded. In contrast, the Galaxy Z Fold8 comes in at 154.9 x 129.9 x 6.3 mm unfolded, and 154.9 x 67.1 x 13.4 mm folded. The two devices are remarkably close in dimensions, with differences measured in fractions of a millimeter. Apple’s foldable is marginally thinner when open, while Samsung’s is a hair thinner when closed. Both weigh around 253 grams, making them substantial but manageable for a foldable.
In practice, the short and wide design means both phones offer a more tablet-like experience when unfolded, and a compact, almost square shape when folded. Neither device will slip into a pocket as easily as a traditional bar phone, but they are surprisingly portable given their expansive screens. The similarity in size suggests that Apple has carefully studied Samsung’s approach and opted for a proven formula rather than reinventing the wheel.
Display
Cover Screen
The outer displays on both devices serve as the primary interface when the phone is closed. The iPhone Duo features a 5.49-inch OLED cover screen with a resolution of 1080 x 2088 pixels and a 60Hz refresh rate. Samsung’s Galaxy Z Fold8 sports a slightly larger 6.2-inch AMOLED cover display with 904 x 2316 pixels and a 120Hz adaptive refresh rate. On paper, Samsung’s cover screen is bigger, sharper in terms of pixel density, and significantly smoother thanks to its high refresh rate. Apple’s 60Hz panel feels like a step behind, especially for a premium device.
Inner Display
Unfolded, the iPhone Duo reveals a 7.76-inch LTPO OLED display with a resolution of 1812 x 2172 pixels and a 1-120Hz adaptive refresh rate. The Galaxy Z Fold8 counters with a 7.6-inch Dynamic AMOLED 2X panel, also with 1812 x 2172 pixels and a 1-120Hz LTPO refresh rate. The inner screens are nearly identical in size and resolution, and both offer buttery-smooth scrolling and vibrant colors. Apple’s LTPO technology ensures efficient power usage, while Samsung’s Dynamic AMOLED 2X is known for its exceptional brightness and contrast. The key difference here is that Samsung’s cover screen doesn’t compromise on refresh rate, whereas Apple’s does.
Performance
Chipset and RAM
Under the hood, the iPhone Duo is powered by Apple’s A18 Bionic chip, a 3nm processor that has already proven itself in the iPhone 16 series. The Galaxy Z Fold8 runs on Qualcomm’s Snapdragon 8 Gen 4 for Galaxy, also built on a 3nm process. Both chips are top-tier, but they cater to different ecosystems. Apple’s A18 Bionic excels in single-core performance and efficiency, while the Snapdragon 8 Gen 4 offers impressive multi-core scores and advanced AI capabilities. In terms of RAM, the iPhone Duo packs 8GB, while the Galaxy Z Fold8 comes with 12GB. Samsung’s extra memory could provide an edge in multitasking and future-proofing, especially for power users who run multiple apps on the large inner screen.
Storage
Storage options are similar: the iPhone Duo starts at 256GB and goes up to 1TB, while the Galaxy Z Fold8 offers 256GB, 512GB, and 1TB variants. Neither phone supports expandable storage via microSD, so buyers should choose their capacity wisely. Both devices also feature ultra-fast UFS 4.0 storage, ensuring quick app launches and file transfers.
Cameras
Main Cameras
Apple has equipped the iPhone Duo with a triple-camera setup: a 48MP main sensor with sensor-shift OIS, a 12MP ultra-wide lens, and a 12MP telephoto with 3x optical zoom. The Galaxy Z Fold8 also features a triple-camera array: a 50MP main sensor with OIS, a 12MP ultra-wide, and a 10MP telephoto with 3x optical zoom. On paper, Apple’s main sensor has a higher resolution, but Samsung’s 50MP sensor uses pixel binning to produce detailed 12.5MP images. Both systems are capable of capturing excellent photos in various lighting conditions.
Selfie and Under-Display Cameras
For selfies, the iPhone Duo uses a 12MP cover camera and a 4MP under-display camera on the inner screen. The Galaxy Z Fold8 has a 10MP cover camera and a 4MP under-display camera. Apple’s cover selfie camera is slightly higher resolution, but Samsung’s under-display camera has been refined over generations to minimize the visible dot. In practice, the difference is negligible, and both under-display cameras are best suited for video calls rather than high-quality selfies.
Video Recording
Both phones can record 8K video at 30fps and 4K at 60fps. Apple’s cinematic mode and ProRes support give it an edge for professional videographers, while Samsung’s Super HDR and 8K recording offer impressive dynamic range. Overall, the camera hardware is closely matched, and the final image quality will depend heavily on software processing and personal preference.
Battery and Charging
Battery life is crucial for foldables, given their large displays. The iPhone Duo houses a 4,800 mAh battery, while the Galaxy Z Fold8 packs a 4,600 mAh cell. Despite the slightly smaller battery, Samsung’s device benefits from the efficient Snapdragon 8 Gen 4 chip and an optimized LTPO display, which can dynamically adjust refresh rates to save power. Apple’s A18 Bionic is also highly efficient, and the 4,800 mAh battery should easily last a full day of moderate use.
Charging speeds are where Samsung pulls ahead. The Galaxy Z Fold8 supports 45W wired charging, 25W wireless charging, and 15W reverse wireless charging. The iPhone Duo, on the other hand, supports 30W wired charging, 15W MagSafe wireless charging, and 7.5W reverse wireless charging. Samsung’s faster wired and wireless charging means less time tethered to a wall, which is a significant advantage for heavy users. However, Apple’s MagSafe ecosystem offers a wide range of accessories and convenience that Samsung’s wireless charging lacks.
Verdict
Choosing between the iPhone Duo and the Galaxy Z Fold8 ultimately comes down to ecosystem preference and specific priorities. The iPhone Duo impresses with its seamless integration into Apple’s ecosystem, powerful A18 Bionic chip, and a familiar user experience for iPhone loyalists. However, its 60Hz cover screen and slower charging are notable drawbacks compared to the competition.
The Galaxy Z Fold8, on the other hand, offers a more refined foldable experience with a smoother cover display, faster charging, and more RAM. It also benefits from Samsung’s years of expertise in the foldable market, resulting in a polished device that feels mature. If you value raw specifications and flexibility, the Galaxy Z Fold8 is the better choice. But if you’re deeply invested in Apple’s ecosystem and want a foldable that feels like a natural extension of your iPhone, the iPhone Duo is a compelling first attempt.
Both devices represent the cutting edge of foldable technology, and the competition between Apple and Samsung will only drive further innovation. For now, the Galaxy Z Fold8 holds a slight edge in hardware, but the iPhone Duo is a worthy contender that will likely appeal to Apple fans. As always, the best phone for you depends on your needs, preferences, and which ecosystem you call home.
