Apple has officially unveiled the iPhone Duo, its first foldable phone, at a keynote that also introduced the iPhone 18 Pro and Pro Max, Apple Watch Series 12 and Ultra 4, and new Siri features. The iPhone Duo starts at €2,339 and will be available for pre-order on October 16. This marks Apple's long-awaited entry into the foldable market, positioning it against rivals like Samsung and others.

iPhone Duo Design and Displays

The iPhone Duo features a 7.6-inch inner foldable display and a 5.4-inch outer display. Both are Super Retina XDR OLED panels with a nano-textured finish, ProMotion, Always-On support, and a peak brightness of 3,000 nits. This makes them among the brightest and most advanced displays on any phone.

The foldable design allows users to switch between a compact phone and a tablet-like experience. The nano-texture reduces glare, and the high brightness ensures visibility even in direct sunlight.

Performance: Apple A20 Pro Chip

At the heart of the iPhone Duo is the Apple A20 Pro chip, built on a 2nm process. It features a 6-core CPU, a 7-core GPU with Neural Accelerators, and a dual 16-core Neural Engine. This setup promises significant performance and efficiency gains, enabling advanced AI features and smooth multitasking.

The 2nm architecture is a first for Apple, likely delivering better battery life and thermal management compared to previous generations.

Camera System

The iPhone Duo sports a dual 48MP camera system on the back: a main 48MP sensor with telephoto capabilities and 2x optical zoom, plus a 48MP ultra-wide sensor. The main camera includes sensor-shift optical image stabilization.

For selfies and video calls, there's a 12MP Center Stage camera on the outer display, and an under-display FaceTime camera on the inner screen that remains hidden when not in use. This is a clever way to maintain a seamless display without a notch or punch-hole.

Battery Life and Charging

The iPhone Duo uses a dual-battery system, one on each side of the fold. Apple claims up to 31 hours of video playback using the inner display, up to 44 hours with the outer display, and up to 24 hours with combined use.

Fast charging is supported: 50% in about 20 minutes with a cable, or 30 minutes wirelessly via MagSafe or Qi2. This should alleviate concerns about battery life in a foldable form factor.

Connectivity and Other Features

The phone includes USB-C, Wi-Fi 7, and Bluetooth (version not specified). These ensure fast data transfer and future-proof wireless connectivity.
