Apple has spent years watching Samsung, Google, and Motorola iterate on foldable phones. That patience may finally end in September.
Multiple reports now suggest that Apple’s long-anticipated foldable iPhone will debut alongside the iPhone 17 lineup this fall, potentially carrying the “iPhone 17 Air” or even the “Ultra” branding. The device, if it ships as described, would represent the single largest form-factor bet Apple has made since the original iPhone in 2007. And it comes at a moment when the foldable phone market — once dismissed as a niche curiosity — is beginning to mature into something that demands a response from Cupertino.
According to CNET, the foldable iPhone could take the place of the rumored iPhone 17 Ultra in Apple’s fall lineup. The report, drawing on supply-chain intelligence and analyst notes, indicates Apple has been developing a book-style foldable — meaning it opens like a book to reveal a larger internal display, similar in concept to Samsung’s Galaxy Z Fold series — rather than the clamshell flip-phone design popularized by the Motorola Razr and Samsung Galaxy Z Flip.
That distinction matters enormously.
A book-style foldable isn’t just a phone that folds in half for pocketability. It’s a device that unfolds into something closer to a small tablet, giving Apple a product that bridges the gap between the iPhone and the iPad mini in a way no current device does. If Apple prices it at the high end — reports suggest north of $1,899, possibly as high as $2,000 — it would sit comfortably in the Ultra tier, justifying the premium branding.
The timing is tighter than many expected. Earlier forecasts from display analyst Ross Young and supply-chain tracker Ming-Chi Kuo had placed a foldable iPhone somewhere in the 2026 or 2027 window. But momentum has accelerated. Bloomberg’s Mark Gurman reported earlier this year that Apple had moved internal timelines forward, with prototypes reaching an advanced stage. Now, the September 2025 window appears increasingly plausible, though not yet confirmed by Apple itself. Apple, characteristically, has said nothing publicly.
So what do we actually know about the hardware?
The foldable iPhone is expected to feature an approximately 7.9-inch internal display when unfolded and a roughly 5.5-inch external screen when closed. Both panels are anticipated to use OLED technology with ProMotion 120Hz refresh rates. Samsung Display is reportedly the primary supplier for the foldable panels, a detail first surfaced by Korean outlet The Elec and corroborated by multiple analysts. Apple has allegedly been working closely with Samsung on achieving a crease that’s less visible than what current Galaxy Z Fold models exhibit — a detail that could prove critical in Apple’s marketing pitch. The crease has long been the aesthetic Achilles’ heel of foldable phones, and Apple’s design team, led by hardware chief John Ternus, reportedly views minimizing it as non-negotiable.
The processor inside is expected to be the A19 Pro chip, the same silicon likely powering the iPhone 17 Pro and Pro Max. That would give the foldable flagship-class performance, including on-device AI capabilities tied to Apple Intelligence features. Camera specifications are less clear. Some reports suggest a dual-camera system rather than the triple-lens array found on Pro models, a potential compromise driven by the thinness requirements of a foldable chassis. But other leaks have pointed to a periscope telephoto lens making the cut. The final configuration remains uncertain.
One of the more interesting wrinkles involves branding strategy. Apple has used the “Ultra” label sparingly — the Apple Watch Ultra, the M-series Ultra chips — always to denote the highest-performance, highest-price variant. If the foldable iPhone launches as the iPhone 17 Ultra, it signals that Apple views the foldable form factor not as an experiment but as the pinnacle of its phone lineup. That’s a bold statement. It would mean Apple isn’t hedging. It’s going all in.
But there’s a counterargument. Some analysts, including Jeff Pu at Haitong International Securities, have suggested the foldable could launch under a distinct product name entirely — something like “iPhone Fold” — to separate it from the numbered iPhone line. This would give Apple room to iterate on the foldable without cannibalizing the Pro Max, which remains its highest-volume premium phone. The naming question isn’t academic. It shapes consumer expectations, carrier partnerships, and trade-in valuations.
The competitive context is impossible to ignore. Samsung launched its first Galaxy Z Fold in 2019 and is now on its sixth generation. Google shipped the Pixel Fold in 2023 and followed with the Pixel 9 Pro Fold in 2024. OnePlus, Xiaomi, and Honor have all released foldables with increasingly thin profiles and improved durability. Apple is late. Undeniably late. But Apple has a long history of entering categories after competitors and then redefining the terms of competition — the iPod wasn’t the first MP3 player, the iPhone wasn’t the first smartphone, and the Apple Watch wasn’t the first smartwatch.
The question is whether the foldable market is ready for that kind of redefinition, or whether it’s still too early-stage for even Apple’s marketing and distribution machine to push it mainstream. Global foldable shipments reached roughly 16 million units in 2024, according to estimates from Counterpoint Research. That’s a fraction of the 1.2 billion smartphones shipped worldwide. Samsung commands the lion’s share but has seen growth plateau. An Apple entry could expand the total addressable market significantly — or it could confirm that foldables remain a high-margin niche.
Price will be the critical variable. At $1,899 to $2,000, the foldable iPhone would cost nearly twice as much as a standard iPhone 17 and significantly more than the iPhone 17 Pro Max. Apple’s install base is enormous — over 1.2 billion active iPhones globally — but the subset willing to pay $2,000 for a phone is considerably smaller. Carrier installment plans and trade-in programs will soften the sticker shock, as they always do. Still, Apple will need to articulate a clear value proposition beyond “it folds.” The iPad mini starts at $499. Why would someone pay four times that for a foldable phone that approximates a mini tablet?
The answer likely lies in software. Apple’s tight integration of hardware and software has always been its competitive moat. A foldable iPhone running iOS 19 — expected to debut at WWDC in June 2025 — could offer multitasking capabilities currently impossible on a standard iPhone. Think split-screen apps, drag-and-drop between panes, and a desktop-class Safari experience on the unfolded display. Apple Intelligence features, including on-device large language models and advanced Siri capabilities, could also be optimized for the larger screen real estate. If Apple can make the unfolded experience feel genuinely different from using a regular iPhone — not just bigger, but fundamentally more capable — the price premium becomes justifiable.
There are risks. Durability remains a concern with all foldables. The flexible display materials are inherently more fragile than the ceramic shield glass on standard iPhones. Hinge mechanisms add moving parts and potential failure points. Apple’s warranty and AppleCare+ terms for a foldable device will be closely scrutinized. Battery life is another question mark. Foldable phones must power two displays and a more complex thermal system within a thinner chassis. Samsung’s Galaxy Z Fold6 has made strides here but still lags behind slab-style flagships in endurance tests.
And then there’s the weight. Current book-style foldables tend to be heavier than traditional phones — the Galaxy Z Fold6 weighs 239 grams, compared to 227 grams for the Galaxy S25 Ultra. Apple has been aggressively pursuing lighter designs; the rumored iPhone 17 Air is expected to be the thinnest iPhone ever made. Applying that engineering ethos to a foldable would be challenging. Reports suggest Apple is using titanium for the frame and has developed a proprietary hinge mechanism that’s both lighter and more durable than competitors’ designs, but these claims are unverified.
The supply chain tells its own story. Apple has reportedly placed initial component orders with Samsung Display, LG Display, and several Chinese suppliers for hinge components and ultra-thin glass cover materials. Production is expected to ramp in the June-July timeframe for a September launch, following Apple’s typical manufacturing cadence. Yields on foldable displays have historically been lower than flat panels, which could constrain initial supply. If Apple launches the foldable iPhone this fall, expect limited availability in the first few weeks — a pattern familiar to anyone who’s tried to order an Apple Watch Ultra or a new Pro model at launch.
Wall Street is paying attention. Analysts at Morgan Stanley, JPMorgan, and Wedbush have all published notes in recent months discussing the revenue implications of an Apple foldable. Dan Ives at Wedbush has estimated that a foldable iPhone could add $15 billion to $20 billion in incremental revenue in its first full year, assuming Apple captures even a modest share of its existing upgrade base. That’s a meaningful number for a company generating roughly $390 billion in annual revenue. It’s also speculative, built on assumptions about pricing, volumes, and adoption rates that won’t be testable until the product actually ships.
The broader strategic picture matters too. Apple’s iPhone revenue growth has slowed in recent years as upgrade cycles lengthen and the smartphone market matures. Services revenue has picked up the slack, but investors want to see hardware innovation that drives new purchase occasions. A foldable iPhone — especially one positioned as the ultimate iPhone — could re-energize the upgrade cycle in a way that incremental camera and chip improvements no longer can. It’s the kind of product that gets people to walk into an Apple Store just to hold it.
Not everyone is convinced September is realistic. Noted Apple analyst Kuo wrote on his Substack earlier this year that mass production challenges could push the launch into early 2026. Display supply-chain consultant Bob O’Donnell of TECHnalysis Research has similarly cautioned that Apple’s quality standards for crease visibility and hinge durability may require more time than the current timeline allows. A delay wouldn’t be unprecedented — Apple pushed back the original HomePod and AirPower (which was ultimately canceled) when engineering challenges proved more stubborn than anticipated.
But the signals pointing toward September are strong and getting stronger. Component orders are reportedly on schedule. iOS 19 beta builds have allegedly included references to foldable display configurations. And Apple’s retail teams have begun receiving updated fixture plans for fall store layouts, a mundane detail that often serves as a reliable leading indicator of new product categories.
If it happens, September 2025 will be one of the most consequential iPhone launches in years. Not just because of the foldable itself, but because of what it says about Apple’s willingness to take risks in a hardware category it didn’t invent and doesn’t yet dominate. The company that perfected the glass slab is about to bet that the future bends.
We’ll know soon enough whether that bet pays off.
