Apple has done what the industry had been predicting for years. With the iPhone Duo, the company has entered the foldable market with a book-style handset that opens into the largest display ever fitted to an iPhone.

The launch is also a changing of the guard. The Duo is the first major product of the John Ternus era — he took over as Apple’s CEO on September 1, just eight days before unveiling the device at Apple Park.

And then came the rush. Pre-orders opened on October 16, and initial stock vanished within minutes — about 15 minutes in the US, according to reports, and under an hour in India. Fresh orders are now showing delivery dates in January 2027, as the Free Press Journal reported this week. So is the Duo genuinely that good, or is this scarcity at work? The Financial Express put that exact question to analysts. Our first look below covers what the device itself offers.

Key Takeaways

• Apple’s first foldable iPhone, announced on September 9, goes on sale on October 23.
• It pairs a 5.4-inch outer display with a 7.6-inch inner display in a Grade 5 titanium body.
• Prices start at $1,999 in the US and ₹2,99,900 in India — the most expensive iPhone ever.
• Pre-orders sold out within minutes; new orders now face a January 2027 delivery window.

iPhone Duo: Quick Specifications

Specifications as listed by Apple and summarised by MacRumors.

Unboxing: What Is in the Box?

The first thing you notice is the box itself. Because the Duo ships unfolded and flat, the packaging is slim and wide rather than deep — and there is very little inside beyond the phone and a 1-metre USB-C cable.

In hand, the surprise is the weight. For a device that opens into a 7.6-inch screen, the Duo feels far lighter than its size suggests — closer in spirit to the ultra-thin iPhone Air than to a small tablet.

The Question Everyone Asks: Can You See the Crease?

Short answer: barely, if at all. Apple has built the hinge from more than 100 precision components, and when the device is opened flat, the inner screen looks smooth, with no visible crease line running down the middle.

The hinge also holds its position at any angle. Half-fold the Duo and it stays exactly where you leave it — a small detail that, as the comparison below shows, makes a real difference in daily use.

Watch: The First iPhone Duo Unboxing

The first unboxing clips surfaced online on October 20, three days before the official launch, as AppleInsider reported. This early hands-on from the Kingmi Mobile channel shows the device coming out of its box and the near-invisible crease in action:

Key Features, Tested by Daily Use

A Display Built for Bright Rooms

The 7.6-inch inner display is 50% larger than the one on the iPhone 18 Pro Max. Its nano-texture finish cuts reflections dramatically, so reading, editing and working outdoors in sunlight stays comfortable in a way glossy foldable screens rarely manage.

Multitasking That Finally Feels Natural

Split View is where the Duo earns its keep. An editing app such as CapCut can run on one half of the screen while notes or a script stay open on the other — and app pairs can be saved, so your work layout is one tap away.

Support for the USB-C Apple Pencil on both displays is also coming later this year, which pushes the Duo further into iPad Mini territory.

A Camera That Hides Away

Unfold the phone and there is no notch interrupting the big screen. The FaceTime camera sits beneath the display, appearing only when needed, while Touch ID is built into the side button.

Battery: Three Numbers, One Story

Apple uses a dual-battery system — one cell on each side of the hinge — managed as a single unit. As MacRumors summarises from Apple’s figures, you get up to 44 hours of video playback on the outer display, up to 31 hours on the inner display, and up to 24 hours of typical mixed use. Fast charging restores 50% in about 20 minutes.

Built Like a Flagship Should Be

The frame is Grade 5 titanium, with Ceramic Shield 2 on the front — which Apple says offers three times better scratch resistance than the previous generation — and an IP68 rating for water and dust resistance, a first-tier credential few foldables carry.

iPhone Duo vs Samsung Galaxy Z Fold 8

The natural rival is Samsung’s Galaxy Z Fold 8, unveiled in July. Put side by side, three differences stand out in hands-on use.

Hinge and Stability

The Duo’s hinge holds any angle firmly, so the phone can sit half-open like a miniature laptop. Samsung’s fold, in comparison, tends to spring fully open and does not settle as reliably at intermediate angles.

Camera Bump and Feel

The Duo’s camera bump is noticeably thicker. Samsung’s device feels a little slimmer in the hand as a result.

Display Finish

Samsung’s screen is glossy and reflective. The Duo’s matte nano-texture finish is easier on the eyes over long sessions — the trade-off serious readers and editors will feel most.

Made for Long Journeys and Long Series

This is where the form factor clicks. On the big inner screen, a Hollywood series — or a favourite show starring someone like Kaley Cuoco — fills the frame and feels genuinely cinematic, helped by the fact that both displays share the same aspect ratio, so content moves between screens without awkward jumps.

Travelling, with no space to open a laptop, half-fold the Duo on a tray table: controls or a keyboard take the lower half, your series or your script takes the upper. Stood on a desk in stand mode, it is just as happy running a retro Walkman app or a casual game.

iPhone Duo Price in India

AppleCare+ for the Duo costs ₹51,900, and card offers bring up to ₹7,000 in discounts, according to the Free Press Journal’s pricing report linked above.

Should You Buy It — or Wait?

If you have ever wished your iPhone could turn into an iPad Mini the moment work or a long flight demands it, the Duo is that wish, answered. The crease-free-feeling display, the hinge that behaves like a laptop’s, and battery figures that shame most foldables make it a complete device, not a first-generation experiment.

The honest caveats are price and patience. At ₹2,99,900 this is the most expensive iPhone Apple has ever sold, and if you order today, January 2027 is when it is likely to reach your door. Buy it if the big screen will earn its keep every day. Wait if it will not — because at this price, it has to.
