iPhone Duo Singapore: Price, Release Date, Specs & Everything You Need to Know

Apple has officially introduced the iPhone Duo, its first foldable iPhone and one of the biggest changes to the iPhone design in years. Instead of choosing between a regular smartphone and a larger tablet-style display, the iPhone Duo combines both ideas in one device: a compact 5.4-inch outer screen for everyday use and a much larger 7.6-inch folding display when opened.

The iPhone Duo in Singapore starts from S$3,099 and comes in four storage capacities: 256GB, 512GB, 1TB and 2TB. Pre-orders begin at 8pm SGT on 16 October 2026, with official availability starting on 23 October 2026.

In this guide, we cover everything you need to know about the iPhone Duo in Singapore, from price and release date to display, performance, cameras, battery, colours and storage options, plus the key things to consider before buying Apple’s first foldable iPhone.

📱 Apple’s First Foldable iPhone

The biggest difference between the iPhone Duo and every previous iPhone is immediately obvious: it folds. Apple has designed the phone around a precision hinge and a Grade 5 titanium body, allowing it to work as a compact phone when closed and a larger-screen device when opened.

When folded, the iPhone Duo measures just 84.1mm wide and uses its outer display like a normal iPhone. Open it up and the body becomes only 5.2mm thick, revealing the largest display Apple has ever placed on an iPhone. The device weighs 254g, so it is noticeably heavier than a conventional iPhone, but the extra weight comes with a much larger usable screen area.

Durability is also a major part of the design. The iPhone Duo uses Ceramic Shield 2 on the outer display, Ceramic Shield on the rear, a reinforced folding display structure and an IP68 water and dust resistance rating. The side button also includes Touch ID, giving users a consistent way to unlock the phone whether it is open or closed.

✨ Two Displays: 5.4-Inch Outside, 7.6-Inch Inside

The iPhone Duo uses two Super Retina XDR OLED displays. The outer screen measures 5.4 inches, while the inner folding display expands to 7.6 inches. Both displays support ProMotion with adaptive refresh rates of up to 120Hz, Always-On display, HDR, True Tone and up to 3,000 nits of peak outdoor brightness.

The larger inner display is where the foldable design becomes useful. It provides more room for watching videos, browsing websites, reading documents, gaming and working with more than one app at the same time.

Apple has also added a nano-texture finish to the inner display to reduce glare and make the crease less distracting during normal use.

Apple has confirmed support for Apple Pencil (USB-C) later in 2026, giving users another way to take notes, mark up documents or sketch directly on the larger screen.

🪟 iOS 27 Brings Split View and New Foldable Experiences

A foldable phone only makes sense if the software can use the extra screen space, and Apple has redesigned parts of iOS 27 specifically for the iPhone Duo. The interface automatically adapts as the phone is opened, closed, rotated or placed at different angles.

One of the biggest additions is Split View multitasking, which allows two apps to run side by side on an iPhone.

Users can browse Safari while checking another app, keep a conversation open next to content they are viewing, or even open two windows of the same supported app.

The folding design also allows the iPhone Duo to stand on a surface without a separate stand. This can be useful for FaceTime calls, watching videos, following workouts or using StandBy at an adjustable viewing angle.

⚡ A20 Pro Performance with Vapour Chamber Cooling

Inside the iPhone Duo is Apple’s A20 Pro chip, paired with a 6-core CPU, 7-core GPU with Neural Accelerators and a Dual 16-core Neural Engine.

Apple also uses an advanced thermal system with a custom vapour chamber to help sustain performance during demanding tasks.

That combination is designed for workloads that can take advantage of the larger display, including multitasking, gaming, photo and video editing, and on-device Apple Intelligence features.

The iPhone Duo also supports Wi-Fi 7, Bluetooth 6 and 5G connectivity.

🔋 Dual-Battery Design and Up to 44 Hours of Video Playback

To make better use of the space on both sides of the foldable body, Apple uses a dual-battery system inside the iPhone Duo. The two batteries work together as one power system.

Apple rates the phone for up to 31 hours of video playback on the inner display and up to 44 hours on the outer display.

For users who alternate between both screens, Apple quotes up to 24 hours of typical usage per charge.

Fast charging is also supported. With a compatible 60W-or-higher USB-C power adapter, the iPhone Duo can reach around 50% charge in approximately 20 minutes.

MagSafe and Qi2 wireless charging are supported at up to 25W.

📸 48MP Dual Fusion Camera System

The iPhone Duo features a 48MP Dual Fusion camera system with a 48MP Fusion Main camera and a 48MP Fusion Ultra Wide camera.

The main sensor also provides an optical-quality 2x option, while the Ultra Wide camera supports macro photography.

The foldable design also introduces camera features that are difficult to reproduce on a regular phone.

With Duo Preview, the person being photographed can see the framing on the outer display.

Smart Take can automatically capture a photo when the group is ready, while Kid Cue uses animations on the outer screen to help attract a child’s attention towards the camera.

For video, the iPhone Duo supports Dolby Vision recording at up to 4K 120fps using the main camera.

It also includes a 12MP Center Stage front camera and an under-display FaceTime camera for calls when the larger inner display is in use.

🏁 A New Direction for the iPhone

At a starting price of S$3,099, the iPhone Duo in Singapore sits firmly at the premium end of the smartphone market.
