Quick Answer: Apple has introduced iPhone Duo, a foldable and posable iPhone with the largest display on any iPhone. It starts at $1,999 and combines a 7.6-inch folding display, a 5.4-inch outer display, the A20 Pro chip and a 48MP Dual Fusion camera system.

iPhone Duo is Apple's foldable iPhone. Closed, it works through a 5.4-inch outer display. Open it and the 7.6-inch folding screen becomes the largest display Apple has put on an iPhone.
The official specification list also clarifies where iPhone Duo sits in the lineup. This is a display-first device built around flexible use, two high-resolution rear cameras and new fold-aware software—not an iPhone Pro with every Pro camera control carried over.
How Much Does iPhone Duo Cost?
Apple lists iPhone Duo from $1,999 in the United States. That is the only price confirmed in the current information.
Apple's comparison details provided here do not identify the base storage capacity, higher-capacity prices, preorder date or retail availability date. We will add those details only when they appear on Apple's official Store, Newsroom or technical-specifications pages.
The $1,999 starting point makes iPhone Duo a premium device. The value proposition is the folding screen and the new ways that iOS can adapt to the phone's position, rather than a simple year-over-year processor upgrade.
iPhone Duo Display Sizes and Features
iPhone Duo has a 7.6-inch Super Retina XDR folding display with nano-texture. Apple calls it the largest display on any iPhone.
On the outside is a 5.4-inch Super Retina XDR display. It lets users handle normal phone tasks without opening the device.
Apple lists ProMotion, an Always-On display and Dynamic Island among the official display features. The comparison information does not specify whether every listed feature applies identically to both screens, so this article does not assign unconfirmed refresh rates or brightness figures to either panel.
What Does Foldable and Posable Mean?
Apple shows iPhone Duo in tent, book and laptop-style positions. The hinge can hold the device at different angles instead of limiting it to fully open or fully closed use.
Book mode
The fully open 7.6-inch screen creates more room for reading, viewing content and working across the wider canvas.
Laptop-style mode
A partly folded position can separate content and controls across the two halves when an app supports the layout.
Tent mode
The phone can stand on its edges for hands-free viewing without relying on a separate kickstand.
Duo Preview
Apple lists Duo Preview as a camera feature, using the two-display design to change how a subject can view the shot.
Apple describes the software as “reimagined iOS experiences for ultimate versatility.” The official summary does not yet provide a complete list of supported multitasking layouts or compatible apps, so specific workflows should be verified as Apple publishes more detail.
How Durable Is iPhone Duo?
Apple describes iPhone Duo as foldable, posable and durable. The confirmed material specification lists a titanium frame and titanium hinge cover.
Those materials help explain how Apple is positioning the device, but the current information does not include a water-resistance rating, dust-resistance rating, fold-cycle test number, exact dimensions or weight. Those figures should not be inferred from earlier reports.
What Is Inside the A20 Pro Chip?
iPhone Duo uses the A20 Pro chip. Apple lists a 6-core CPU, a 7-core GPU with Neural Accelerators, a Dual 16-core Neural Engine and hardware-accelerated ray tracing.
| A20 Pro component | Official iPhone Duo specification |
|---|---|
| CPU | 6 cores |
| GPU | 7 cores with Neural Accelerators |
| Neural Engine | Dual 16-core Neural Engine |
| Graphics | Hardware-accelerated ray tracing |
Apple does not list the fabrication process or memory capacity in the information provided here. Those previously rumored numbers have been removed from this version.
iPhone Duo Rear Camera Specifications
The rear camera is officially called a 48MP Dual Fusion camera system. It combines a 48MP Fusion Main camera and a 48MP Fusion Ultra Wide camera.
Apple lists 0.5x, 1x and 2x optical zoom options. Because there is no dedicated Telephoto camera in the listed system, buyers who regularly photograph distant subjects should compare the Duo with Apple's Pro models.
For still photos, confirmed features include super-high-resolution 24MP and 48MP images, Smart Take, Duo Preview, Photographic Styles 3, next-generation portraits with Focus and Depth Control, and macro photography.
For video, iPhone Duo supports Dolby Vision up to 4K at 120 fps, Smart focus tracking, Cinematic mode effects from video and improved low-light video.
Apple also makes the omissions clear: iPhone Duo does not include Pro controls, Apple Reference Image on the Fusion Main camera, or the ƒ/1.48, ƒ/1.8, ƒ/2.8 and ƒ/4.0 variable-aperture options shown for applicable Pro models.
What Can the 12MP Center Stage Front Camera Do?
iPhone Duo has a 12MP Center Stage front camera and an under-display FaceTime camera.
Confirmed features include tap to zoom and rotate, Center Stage for photos, ultra-stabilized video, Dual Capture and Center Stage for video calls. This makes the front-camera experience a significant part of the foldable design rather than a basic specification carried over unchanged.
iPhone Duo Battery Life: Outer vs Inner Display
Apple provides two official battery-life numbers because screen choice changes power use:
| Video playback test | Official rating |
|---|---|
| Using the outer display | Up to 44 hours |
| Using the inner display | Up to 31 hours |
The 13-hour difference is important. Buyers who use the outer screen for most phone tasks can expect a different battery profile from users who spend the day reading, gaming or watching video on the 7.6-inch folding display.
These are Apple's video-playback ratings, not promises of identical real-world screen-on time. Network conditions, brightness, apps, camera use and background activity can all change battery life.
Does iPhone Duo Have an Action Button?
No. Apple's comparison information explicitly lists no Action button on iPhone Duo.
It does include Camera Control for faster access to photo and video tools. That choice reinforces the Duo's emphasis on its camera interface while distinguishing its physical controls from the current Pro layout.
Does iPhone Duo Support Apple Intelligence and Siri AI?
Yes. Apple lists both Apple Intelligence and Siri AI for iPhone Duo, subject to Apple's footnotes covering availability, language and regional requirements.
The A20 Pro's Neural Accelerators and Dual 16-core Neural Engine provide the on-device hardware foundation. Exact features can still depend on the iOS version, language, region and Apple's rollout schedule.
What Apple Has Not Confirmed in This Specification Update
The following details are not included in the Apple information used for this revision and are therefore intentionally absent from the specification cards:
Ordering
Base storage, higher storage tiers, preorder date, release date and launch countries.
Physical details
Exact dimensions, folded thickness, unfolded thickness, weight and colors.
Charging
USB-C wattage, MagSafe or Qi2 support, wireless wattage and fast-charge time.
Other features
Biometric method, water/dust rating, Apple Pencil compatibility and an official fold-cycle number.
Who Should Buy iPhone Duo?
iPhone Duo is for buyers who will genuinely use the 7.6-inch inner display. The strongest reasons to choose it are reading, media, fold-aware apps, hands-free viewing and the flexibility of switching between an outer phone screen and a much larger inner canvas.
Camera-focused buyers should note the tradeoffs. The two 48MP rear cameras cover Main and Ultra Wide perspectives, but Apple explicitly omits Pro controls, Apple Reference Image, variable-aperture options and a dedicated Telephoto camera from the listed system.
At $1,999, the purchase decision should come down to the folding experience. If you do not expect to use the larger display regularly, a conventional iPhone may offer a better balance of price, cameras and accessory simplicity.
