Foldable phones just got a lot more interesting. Apple’s iPhone Duo is finally official, and it lands directly across the ring from the phone that has owned this shape of device all year: the Samsung Galaxy Z Fold 8. Both are wide, book-style foldables. Both sit close to the two-thousand-dollar mark. And both companies are convinced they have cracked the format.
We already broke down Apple’s debut foldable in our iPhone Duo first look. This time, we are putting it side by side with Samsung’s current champion to see who wins on paper, and who actually deserves your money. For an even deeper spec-by-spec breakdown, PhoneArena’s own comparison is a solid companion read.

A New Chapter for Apple
There is a story behind this launch that goes beyond specs. At Apple’s September 9 event, it was not Tim Cook who unveiled the iPhone Duo. Cook made only a brief cameo, and it was John Ternus, Apple’s new CEO, who introduced the company’s first-ever foldable to the world. It is a fitting moment for Apple to hand the mic to new leadership: a brand new device category, unlike anything the iPhone line has tried before.
Samsung, on the other hand, is not new to this. The Z Fold 8 is the eighth generation of Samsung’s mainline foldable, and the company has had years to refine the hinge, the software, and the price positioning. It also lands just months after Samsung refreshed its slab flagships with the Galaxy S26 series, so 2026 has already been a busy year on that side. That head start shows up throughout this comparison.
Design and Build Quality
Apple went all in on durability with the iPhone Duo. It uses a titanium hinge and frame, a Ceramic Shield glass back, and Ceramic Shield 2 across the outer screen. The result is an IP68 rating for dust and water resistance, a rarity in foldables that only the Google Pixel 11 Pro Fold currently matches. The inner display uses a seven-layer stack that Apple says moves like the pages of a book and resists long-term creasing. Even the FaceTime camera disappears under the screen, leaving the inner display free of any cutout. Touch ID also makes a comeback, built into the hinge or side key.
Samsung took its design in a different direction this year. The Z Fold 8 drops the tall, narrow shape Samsung has used for years in favor of a shorter, wider “passport style” body, a shape that happens to closely echo Apple’s own approach. The old tall-and-skinny form factor did not disappear; it was rebranded as the Z Fold 8 Ultra at a higher price. The standard Fold 8 uses an Armor Aluminum frame with Gorilla Glass Victus 2 on the back, and it carries an IP48 rating, meaning it handles water fine but offers noticeably less protection against dust than the iPhone Duo’s IP68.
One detail worth knowing: Samsung actually manufactures the folding OLED panels used inside the iPhone Duo. Apple’s biggest foldable rival is also one of its suppliers.
Display
Samsung’s Z Fold 8 opens up to a 7.6-inch inner display with a 4:3 aspect ratio, paired with a 5.5-inch cover screen for quick tasks. Apple takes a cleaner approach with the iPhone Duo, giving both the inner and outer displays an identical 14:10 aspect ratio. That consistency means apps and content should look and feel the same whether the phone is open or closed, something Samsung’s mismatched inner and outer ratios cannot quite match. Apple also leans hard on its no-crease claim, a detail that has been the biggest complaint about foldables since the category began.
Performance: A20 Pro vs Snapdragon 8 Elite Gen 5
The iPhone Duo runs on Apple’s A20 Pro, the company’s first 2nm chip and, according to Apple, the fastest silicon ever put in a smartphone. Apple claims a 40 percent faster GPU and 50 percent more memory bandwidth compared to last year’s A19 Pro. The Z Fold 8 uses the Snapdragon 8 Elite Gen 5, a 3nm chip that remains the best Qualcomm has to offer right now, though a newer Snapdragon generation is expected later this year in upcoming Android flagships rather than in this device.
Both phones start with 12GB of RAM and 256GB of storage. Samsung bumps RAM to 16GB once you step up to the 512GB or 1TB tiers, while Apple has not disclosed the Duo’s RAM at any storage level but does offer a massive 2TB option for buyers who want the most space a foldable has ever carried.
Camera Comparison
Neither phone bothers with a dedicated telephoto lens. Both stick to a main and an ultra-wide module on the back, which is a bit surprising given how much both companies charge for these devices. Apple’s main sensor is slightly larger at 1/1.28 inches, compared to Samsung’s 1/1.56-inch sensor, which should help the Duo in low light even without more megapixels or extra zoom hardware.
Battery Life and Charging
Samsung is upfront about its numbers: a 4,800mAh battery, 45W wired charging, and 20W wireless charging. Apple, as usual, keeps the battery capacity to itself. Instead, the company quotes up to 31 hours of video playback using the inner display and up to 44 hours using the outer screen. What Apple does confirm is 25W wireless charging on the iPhone Duo, which edges out the Z Fold 8’s 20W wireless speed, even though Samsung’s 45W wired option remains the faster way to top up either phone.
Multitasking and Software
This is where Samsung’s experience really shows. The Z Fold 8 can run three full apps side by side, add floating windows on top of that, let you drag files between them, and pin your favorite app combinations for quick access. Plug it into an external monitor and Samsung DeX turns the phone into something close to a desktop computer. It is one of the most capable multitasking setups on any phone today.
Apple’s iOS 27 introduces split-screen multitasking to the iPhone for the very first time, letting the Duo run two resizable apps at once and save favorite app pairs for later. It is a genuine leap for iPhone users, but next to Samsung’s three-app, floating-window, DeX-ready system, it still feels like a first-generation feature finding its footing.
Price and Availability
The Galaxy Z Fold 8 has been shipping since August and is already a hit. Counterpoint Research reports the Fold 8 is outselling last year’s Fold 7 by 30 percent in its first month on shelves, and it is pulling in 57 percent of all Z8-series sales compared to its pricier Ultra sibling. Pricing starts at $1,899 for the 256GB model and climbs to around $2,500 for the 1TB, 16GB configuration.
The iPhone Duo has a longer wait ahead of it. Preorders open roughly a month after the September 9 announcement, with the phone shipping from October 23, 2026. Pricing starts at $1,999 for 256GB and rises all the way to $3,199 for the 2TB model, Apple’s most expensive iPhone configuration yet. For readers weighing a standard flagship instead of a foldable, our iPhone 18 Pro vs Galaxy S26 Ultra comparison is worth a look too.
Which Should You Buy?
Choose the iPhone Duo if durability, a crease-free display, and tight iOS integration matter most to you. Its IP68 rating, Touch ID, and matching-ratio dual screens make it feel like the more polished first attempt, even if you will need to wait until late October to actually get one.
Choose the Galaxy Z Fold 8 if you want the more capable multitasking experience, a lower starting price, and a phone you can buy today rather than preorder. Samsung’s years of foldable experience are obvious the moment you start running three apps at once or plugging into a monitor with DeX.
Either way, this is the first year Apple and Samsung are going head to head in the same foldable shape, and that rivalry alone should push both phones forward fast.
