iPhone Duo Specs & Price in Singapore

iPhone Duo is built around one standout number: a 7.6-inch inner display that Apple calls the largest screen ever fitted to an iPhone, roughly 50 per cent larger than iPhone 18 Pro Max. Closed, its 5.4-inch outer display covers more than 90 per cent of the screen area on iPhone 18 Pro, so it still works as a normal, pocketable phone when you don't need the bigger canvas.

Both displays share the same aspect ratio, run up to 3,000 nits peak brightness, and support ProMotion up to 120Hz. The inner display uses a custom nano-texture coating designed to cut glare and keep the fold itself as unobtrusive as possible when the phone is open.

Under the hood, iPhone Duo runs the same A20 Pro chip as iPhone 18 Pro and Pro Max, so performance for gaming, editing and on-device AI stays consistent across the whole lineup. It introduces an iPhone-first dual-battery system, rated for up to 31 hours of video playback on the inner display or up to 44 hours using the outer display alone, with a roughly 20-minute charge to 50 per cent.

The camera system is a 48MP Dual Fusion setup — a 48MP Fusion Main and 48MP Fusion Ultra Wide on the back, up to 2x optical-quality zoom, plus a 12MP Center Stage front camera and a second, under-display camera built into the inner screen itself.

Build-wise, iPhone Duo uses a Grade 5 titanium frame and hinge, Ceramic Shield front and back, a scratch-resistant coating on the inner display, and IP68 water and dust resistance. It comes in Night Sky and Star White, with storage from 256GB up to 2TB. One thing worth knowing before you switch: iPhone Duo is eSIM-only with no physical SIM slot, and it uses Touch ID built into the side button rather than Face ID.

iPhone Duo price in Singapore starts from $0 upfront on an eligible Bespoke Flexi plan when you pre-order with M1. Pre-order opens 8pm Singapore time on 16 October until 22 October, with retail launch also on 23 October — mark this as the iPhone Duo pre-order date and launch date if you're planning your purchase.

What Makes iPhone Duo Different

A few features are unique to iPhone Duo's folding design.

• Duo Preview lets your subject see a live view on the outer screen while you shoot, so they know exactly how the photo will look before you take it.
• Smart Take waits until everyone's ready before firing the shutter, cutting down on blinks and half-smiles.
• Kid Cue uses playful animations on the outer display to naturally draw kids' eyes to the lens, making it easier to get them looking at the camera.
• Duo FaceTime lets someone standing nearby join a call using the outer display, without needing to unfold the phone.

iPhone Duo vs iPhone 18 Pro Max — Which Should You Get?

Both A20 Pro-powered iPhones share the same chip, so raw performance won't be the deciding factor. iPhone Duo is a genuinely different category: a foldable with a 7.6-inch inner display for multitasking and media, in a phone that still closes down to a normal, pocketable size. It's the pick if extra screen real estate for split-screen apps, reading, or watching video is something you'd genuinely use day to day — not simply the newest or most expensive option by default.

One practical trade-off worth knowing: iPhone 18 Pro and Pro Max both keep a telephoto lens and variable aperture, which iPhone Duo doesn't have. If zoom photography and low-light shooting control matter most to you, iPhone 18 Pro or Pro Max is the stronger camera choice. If flexible, larger-screen multitasking matters more, iPhone Duo is built specifically for that.

What are the unique features of the Apple iPhone Duo?

iPhone Duo is Apple's first foldable iPhone, with a 7.6-inch inner display Apple calls the largest ever fitted to an iPhone. It introduces features built specifically for its folding design, including Duo Preview, Smart Take, and Duo FaceTime, along with an iPhone-first dual-battery system and a Grade 5 titanium frame.

Is iPhone Duo worth buying over iPhone 18 Pro Max?

It depends on what you value most. iPhone Duo offers significantly more screen space for multitasking and media in a foldable design, but iPhone 18 Pro Max keeps the telephoto lens and variable-aperture camera system that Duo doesn't have. Choose based on whether extra screen real estate or camera versatility matters more to you.

Does iPhone Duo use Face ID like the other iPhone 18 models?

No. iPhone 18 Pro and iPhone 18 Pro Max use Face ID, but iPhone Duo uses Touch ID built into the side button instead, giving you a consistent way to unlock the phone whether it's open or closed.

Is iPhone Duo eSIM-only, or does it support a physical SIM in Singapore?

iPhone Duo is eSIM-only worldwide, including Singapore, with no physical SIM tray at all. If you specifically need physical SIM support, iPhone 18 Pro or Pro Max are the right choice, not iPhone Duo.

What colours does iPhone Duo come in?

iPhone Duo comes in two finishes: Night Sky and Star White, with a Grade 5 titanium frame and hinge.

How much storage do I need for iPhone Duo?

iPhone Duo offers the same four storage options as iPhone 18 Pro and Pro Max: 256GB, 512GB, 1TB, and 2TB. The real question is how you'll actually use that bigger inner display. If you're mostly messaging, browsing, and streaming, 256GB is plenty. Multitasking across split-screen apps, shooting video regularly, or keeping a large photo library will eat into that faster than on a standard iPhone, so 512GB or 1TB is worth considering. 2TB suits heavy users, such as professional content creators or anyone managing large video libraries. Not sure where you land? Check your current phone's storage usage in Settings before deciding.

Can I trade in my old iPhone for iPhone Duo?

Yes. M1 offers a trade-in programme that lets you exchange your current device for credit toward iPhone Duo, reducing the amount you pay upfront.

Does iPhone Duo support 5G in Singapore?

Yes, iPhone Duo supports 5G connectivity in Singapore, backed by M1's 5G network for faster downloads, streaming, and browsing.
