Apple's Foldable iPhone Changes Everything — and Samsung Is Already on the Back Foot

Apple just rewrote the rules of the smartphone market.

For years, the foldable phone narrative belonged to Samsung. The Korean giant bet early, refined its hinge technology through generations, and cultivated the assumption that if you wanted a phone that folded, you bought a Galaxy Z Fold. Apple stayed on the sidelines—not out of inability, but strategy. It waited until the form factor was mature enough to not embarrass itself, and then it arrived with a device that may well make Samsung’s foldable experiments look like rough drafts.

The iPhone Duo, unveiled at Apple’s first fall event under newly appointed CEO John Ternus, is a 7.6-inch Retina display when unfolded with a 5.4-inch outer screen. It has an underdisplay camera. The hinge contains more than 100 engineered components made from Grade 5 aluminum. Battery life reaches 31 hours on the inner display and 44 hours on the outer. It starts at $1,999. That price is aggressive in the sense that it undercuts the asking prices of comparable Samsung foldables while delivering what Apple calls an iPad-inspired versatility in a pocketable form.

Here’s what most coverage will miss: this isn’t just Apple entering the foldable market. This is Apple redefining what a foldable phone is supposed to be—and in doing so, forcing every other manufacturer, especially Samsung, to defend territory they thought was theirs.

Why Samsung is suddenly playing defense

Samsung launched the original Galaxy Fold in 2019. It faced critical failures—screens cracked, hinges broke, reviewers tore out protective layers. The company spent years iterating. By the time the Galaxy Z Fold6 and Z Flip6 arrived, the hardware was polished, the software adapted, and Samsung had built a loyal niche of early adopters who valued the form factor over the price premium.

Apple didn’t have that lead time. But Apple had something Samsung didn’t: an installed base of nearly 2 billion active iPhones, a supply chain that can absorb enormous volume, and a brand that converts casual interest into massive launch-day demand overnight. The iPhone Duo doesn’t need to convince foldable enthusiasts. It needs to convince the millions of iPhone users who see a large screen as desirable but have never considered a foldable because they assumed the category was built for tech junkies, not regular people.

That’s the real threat to Samsung. Apple isn’t trying to win the foldable segment. Apple is trying to make the foldable segment irrelevant by making it mainstream.

The $1,999 starting price is a calculated move. Samsung’s latest Z Fold series retails for $1,799 to $1,919 depending on configuration. Apple’s pricing is within striking distance, but coming from Apple, it carries a different psychological weight. When Apple makes something expensive, consumers interpret it as premium. When Samsung makes something expensive, consumers interpret it as overpriced. That asymmetry is precisely why Samsung cannot afford to lose this moment.

The supply chain shock

Foldable displays require specialized manufacturing. Samsung Display currently supplies the vast majority of foldable OLED panels to the industry. Apple is reportedly building its own foldable display production capacity and has brought in LG Display and potentially BOE as secondary suppliers. The transition won’t be quick— foldable panel yields remain low across the industry—but Apple’s capital and scale mean it will happen faster than anyone outside the company can predict.

This matters for Samsung because its display division funds a significant portion of its overall hardware R&D. If Apple captures even a meaningful share of foldable display demand, Samsung’s margins shrink and its ability to subsidize Galaxy hardware contracts. The economics of foldables shift in Apple’s favor not because Apple’s components are cheaper, but because Apple’s ecosystem lock-in makes the $1,999 price feel like a good deal to a far larger audience.

The other announcements matter too—but not how you’d think

While the iPhone Duo dominates attention, the rest of Apple’s event reveals a company executing a broader strategy. The iPhone 18 Pro lineup, starting at $1,199 ($100 more than last year), introduces a variable aperture camera with six thin blades, 4K Dolby HDR Vision recording, and new Pro controls for white balance and shutter speed. The incremental nature of these upgrades is deliberate. Apple is slowing the upgrade cycle for non-foldable phones to push consumers toward the Duo when they’re ready to leap.

The Apple Watch Series 12 and Ultra 4 introduce Audio Intelligence features—Live Rewind, which surfaces the previous 15 seconds of conversation as text, and Siri Recap, which summarizes key moments from daily interactions. These aren’t trivial software tweaks. They position Apple’s wearables as AI-driven memory extensions, a category Amazon and Google are scrambling to enter with Alexa and Gemini-powered devices. The watch is becoming a general-purpose audio log, and Apple is building the moat before competitors can catch up.

AirPods 5, starting at $129, improve active noise cancellation by 50% over the previous generation and bring stem-mounted volume controls down from the Pro line. Again, this is product segmentation executed with precision—features that differentiate the Pro tier are now being migrated downward to keep the standard line competitive without eroding margin.

What happens next

The iPhone Duo preorders open October 16, shipping October 23. The iPhone 18 Pro and Pro Max preorders begin Saturday, available September 18. Apple Watch and AirPods preorders start today, shipping the same date as the Pro iPhones.

Within six months, we’ll know whether Apple’s foldable entry achieves the kind of launch-week sellout that defined the original iPhone or falls short of internal targets. Either outcome shifts the market. A smash hit accelerates Samsung’s need to respond with a generational leap—or risk ceding the premium foldable category entirely. A modest result gives Samsung breathing room, but it also proves Apple can compete in this space, which changes how investors and analysts price both companies.

The iPhone Duo is Apple’s boldest hardware statement in years. It’s also a message to every competitor: the era of you-first innovation in foldables is over. Apple is here, and it’s not asking for permission to lead.
