iPhone Duo Arrives at $1,999: Is It Worth the Wait?
Apple unveiled the iPhone Duo, its first foldable iPhone, alongside the new iPhone 18 Pro line, Apple Watch Series 12 and AirPods 5. Prices, dates and highlights from Ternus's first keynote as CEO.
Is a foldable iPhone worth waiting almost a decade for? The short answer is yes, if you have $1,999 to spare and don’t mind that zoom works differently than it does on a Samsung.
Apple finally showed on Wednesday, September 9, what had been leaking through headlines and doctored photos for years. It’s called the iPhone Duo, and it’s the company’s first foldable phone. The unveiling was led by John Ternus, who had taken over as CEO from Tim Cook just eight days earlier, on September 1. It was his first keynote in the role, held under the slogan “Surprise and shine.” After the usual segments on the iPhone, Apple Watch and AirPods, Ternus pulled a classic Apple move. “Actually, there’s one more thing,” he said, then added simply: “It’s the iPhone Duo.”
What Exactly Does the iPhone Duo Offer
Opened up, the inner display measures 7.6 inches, which Apple says is 80 percent larger than the screen on the iPhone 18 Pro. The outer display, used while the phone is folded, measures 5.4 inches. Both are Super Retina XDR panels, and both are driven by the new graphics engine inside the A20 Pro chip.
The body is titanium, with a nano-texture finish meant to hide the crease down the middle, available in white (Star White) and dark (Night Sky) finishes. There’s no Face ID; instead, Touch ID is built into the side button, supporting multiple fingerprints and the ability to unlock via Apple Watch, a solution that reads less like a step backward than a trade-off dictated by the foldable screen’s construction.
The battery is split into two halves, one in each side of the body. Apple lists 31 hours of video playback when using the inner display, and 44 hours on the outer one. Water and dust resistance is rated IP68, matching the rest of the lineup. The Duo is also the first iPhone to work with the Apple Pencil, and the first able to split the screen between two apps at once, useful for comparing prices or working across two windows of the same site.
A correction to one claim that spread widely online: the iPhone Duo does not have three rear cameras. It has two, a 48-megapixel main Fusion camera (f/1.6) and a 48-megapixel ultra-wide (f/2.2). There’s no telephoto lens. Zoom works by cropping into the main sensor, reaching what Apple calls an optical-equivalent 4x, and up to 10x digitally. Anyone after true optical zoom with two lenses should look at the iPhone 18 Pro, not the Duo. Video recording tops out at 4K at 120 frames per second.
Pricing starts at $1,999 for the 256GB version, with storage options up to 2TB. Preorders open October 16, and the phone goes on sale October 23, a week later than the rest of the lineup.
And What About the iPhone 18 Pro?
The iPhone 18 Pro starts at $1,199, and the Pro Max at $1,299. That’s roughly $100 more than the previous generation, and Apple attributes the increase openly to the global memory chip shortage rather than to any new feature that would justify it. Preorders begin Saturday, September 12, with sales starting September 18.
The camera on the Pro models gets a variable aperture for the first time, f/1.48, f/1.8, f/2.8 and f/4.0, which should help in low light without digitally reworking the image. The new colors are Glacier and Burgundy. The Pro Max reaches 45 hours of video playback, making it the longest-lasting battery in the entire lineup, ahead even of the Duo.
Watch, AirPods and Software in the Same Lineup
The Apple Watch Series 12 costs $399, and the Ultra 4 is priced at $799. Both run on the S11 chip and introduce Health Age and Readiness features, an estimate of your “biological age” based on vital signs, along with a suggestion for how much recovery your body needs before the next workout.
The AirPods 5 cost $129 in the base version, or $149 with wireless charging. They arrive September 17, a day before the phones. Apple claims active noise cancellation has improved 50 percent over the previous generation.
Alongside the hardware, Apple announced iOS 27, while the release of macOS 27 Golden Gate was confirmed for September 14, a day before the new phones even reach buyers’ hands.
Was Apple Even in a Hurry?
The reality is that Samsung, Motorola and Google have been making foldable phones for several years already, and Apple is arriving last here, not first. That’s also typical of the company: waiting for a category to mature before stepping in, rather than risking a first generation with growing pains. The question now isn’t whether the iPhone Duo is a good phone on paper, it clearly is, but whether $1,999 and the lack of a telephoto lens change the calculus for someone who already has an iPhone 18 Pro in their pocket. For now, it’s still a phone for someone who already knows they want it, not for someone on the fence.
