iPhone Duo specs include a dual-screen design that marks Apple’s official entry into the foldable phone race after close to a decade of rumors. At its September 9 “Surprise and Shine” event, Apple officially unveiled the iPhone Duo — its first-ever foldable iPhone, and reportedly the most expensive iPhone the company has ever sold. iPhone Duo specs and pricing details are everything confirmed so far, highlighting what it could mean once local pricing lands in Bangladesh.

What Is the Apple iPhone Duo?

The iPhone Duo was unveiled by Apple’s new CEO John Ternus — his first major product launch since taking over from Tim Cook on September 1 — at an event held at Apple Park, Cupertino. Apple is positioning it as the biggest iPhone display ever made, in a body that still folds down to pocket size. It ships in two finishes, Star White and Night Sky, across four storage tiers: 256GB, 512GB, 1TB, and 2TB.

iPhone Duo Specs: Design and Build Quality

Apple built the Duo around a titanium foldable frame, with Ceramic Shield 2 protecting the front and standard Ceramic Shield on the back — the same protective glass family used across the rest of the iPhone 18 lineup, adapted for a hinge. It carries an IP68 rating, meaning it can handle being submerged up to 6 meters for 30 minutes.

Unfolded, it measures 164.6mm × 117.8mm × 5.2mm; folded shut, it shrinks to a pocketable 84.1mm × 117.8mm × 11.3mm, at 254 grams either way.

Two Screens, One Phone

This is where the Duo earns its name. Open it up and you get a 7.6-inch Super Retina XDR OLED inner display (1878 × 2670 at 430ppi) with a nano-texture finish and ProMotion up to 120Hz — and notably, this is the first iPhone in history to support the Apple Pencil (USB-C). Fold it shut, and a 5.4-inch outer OLED display (1398 × 2034 at 460ppi) handles everyday use like a normal phone.

For scale: Apple says the inner display offers roughly 50% more screen area than the iPhone 18 Pro Max, and about 80% more than the standard iPhone 18 Pro. Both screens support Dynamic Island, Always-On display, and peak outdoor brightness of 3,000 nits.

Performance and Apple Intelligence

Powering all of this is the new Apple A20 Pro chip — a 6-core CPU (2 performance + 4 efficiency cores) paired with a 7-core GPU with hardware-accelerated ray tracing, plus a dual 16-core Neural Engine built to run Apple Intelligence and the next generation of Siri on-device.

Cameras

• Rear: 48MP Fusion Main (ƒ/1.6) with a 2x optical-quality telephoto crop, plus a 48MP Ultra Wide with a 120° field of view
• Outer front: 12MP Center Stage camera (ƒ/2.2)
• Inner front: An under-display FaceTime camera (ƒ/1.8) built directly into the folding screen — no notch, no cutout

Video tops out at 4K Dolby Vision at up to 120fps, with Cinematic and Action modes carried over from the rest of the iPhone 18 family.

Battery and Charging

The Duo runs on dual internal batteries, rated for up to 24 hours of typical use, up to 44 hours of video playback on the outer display, or 31 hours using the larger inner screen. Charging is 60W wired (50% in about 20 minutes), plus 25W MagSafe and 25W Qi2 wireless support.

Connectivity and Everyday Use

The Duo runs on dual eSIM only — there’s no physical SIM tray, worth knowing before you switch carriers in Bangladesh. It’s otherwise fully loaded: 5G via Apple’s C2 modem, Wi-Fi 7, Bluetooth 6, second-gen Ultra Wideband, USB-C with USB 3 speeds (up to 10Gb/s) and DisplayPort output, and Apple’s satellite safety features (Emergency SOS, Crash Detection, Find My). Authentication is handled by Touch ID in the side button — there’s no Face ID on this model.

Global Price and Release Date

Apple confirmed the iPhone Duo starts at $1,999 in the US for the 256GB model, climbing to roughly $3,000 for the top-end 2TB configuration — making it the most expensive iPhone Apple has ever sold at launch. Global pre-orders open October 16, with the phone reaching customers from October 23.

That price puts it well above Samsung’s competing foldables — the Galaxy Z Fold 8 starts at $1,899, with the Fold 8 Ultra at $2,099 — making the Duo’s price tag one of the biggest talking points of the launch.

Bangladesh pricing hasn’t been officially confirmed yet. MC Solution BD will update the iPhone Duo product page the moment local pricing is announced — EMI options and full Apple warranty coverage will be available once it does, through our EMI Terms and Apple Warranty pages.

Should You Buy the iPhone Duo?

It’s worth considering if:

• You want the biggest screen Apple has ever put in an iPhone, and you’ll actually use the Apple Pencil support for notes or sketching
• You’re comfortable being an early adopter of a brand-new Apple product category
• Budget isn’t the deciding factor

You might want to wait if:

• You rely on a physical SIM and haven’t confirmed your carrier’s eSIM setup
• You’d rather see real-world hinge durability reviews before committing to a first-generation foldable
• The price gap over a standard iPhone 18 Pro Max is hard to justify for your use case
