The Apple iPhone Duo has been officially announced, marking Apple's long-awaited entry into the foldable smartphone market. After months of speculation, the company unveiled the device at a keynote that also introduced the iPhone 18 Pro and Pro Max, Apple Watch Series 12 and Ultra 4, and new Siri features.
Priced from 2,339 euros, the iPhone Duo will be available for pre-order starting October 16. Here's everything you need to know about Apple's first foldable.
iPhone Duo Design and Displays
The iPhone Duo features a 7.6-inch inner foldable display and a 5.4-inch outer screen. Both use Super Retina XDR OLED panels with a nano-textured finish, ProMotion, Always-On support, and a peak brightness of 3,000 nits.

This dual-screen setup aims to offer the best of both worlds: a compact phone when folded and a tablet-like experience when opened. The nano-textured finish should reduce glare, a first for an iPhone.

Performance: A20 Pro Chip and Battery Life
Under the hood, the iPhone Duo runs on the Apple A20 Pro (2nm) chip, featuring a 6-core CPU, a 7-core GPU with Neural Accelerators, and a dual 16-core Neural Engine. This should deliver top-tier performance for multitasking and AI tasks.

Battery life is impressive thanks to a dual-battery system (one on each side). Apple claims up to 31 hours of video playback using the inner screen, up to 44 hours with the outer screen, and up to 24 hours with combined use. Fast charging gets you to 50% in about 20 minutes via cable or 30 minutes wirelessly with MagSafe or Qi2.

Camera System
The iPhone Duo sports a 48MP Dual Fusion camera system: a 48MP main sensor with telephoto capabilities and 2x optical zoom, plus a 48MP ultra-wide. There's also a 12MP Center Stage camera on the outer screen and a hidden FaceTime camera under the inner display.
This setup should appeal to photography enthusiasts who want flexibility without sacrificing image quality.
