Editorial Overview
This is an editorial analysis of the specifications listed on this page. It is not based on SpecHub lab testing, so it makes no claims about benchmarks, battery life or camera results. Manufacturer lab figures are not reproduced here.
Phone Overview
The iPhone Duo is Apple's first foldable iPhone, announced on September 9, 2026. It opens like a book to a 7.6-inch inner display and has a 5.4-inch cover display for use when closed. The phone goes on sale on October 23, 2026, so the details here come from Apple's announcement rather than long-term use. It is aimed at buyers who want a tablet-sized screen in a phone.
Performance and Processor
It uses the Apple A20 Pro with a six-core CPU (two performance and four efficiency cores) and a seven-core GPU. Apple does not publish RAM, and some retailer listings give figures that Apple has not confirmed, so none is listed here. Storage options are 256GB, 512GB, 1TB and 2TB with no card slot. SpecHub has not benchmarked the phone.
Display Experience
The inner display is a 7.6-inch foldable OLED at 1878 x 2670 pixels with a 4:3 aspect ratio, which suits reading and split-screen work. The 5.4-inch cover display has 1398 x 2034 pixels. Both support an adaptive refresh rate of 1-120Hz, and Apple rates the display for up to 3,000 nits of peak outdoor brightness. The phone also supports an Apple Pencil (USB-C).
Camera Experience
The rear cameras are a 48MP main and a 48MP ultrawide, with no telephoto lens listed. The front side has a 12MP camera plus an under-display camera for the inner screen. Apple's launch material does not give further lens figures in the sources we checked, so they are omitted. SpecHub has not tested image quality.
Battery and Charging
Retail listings report a 5800 mAh battery; Apple does not publish capacity. Apple states about 50% in around 20 minutes with a 60W-capable USB-C adapter, which is not included. Wireless charging runs at up to 25W with MagSafe or Qi2. We have no endurance tests.
Software and Features
The phone ships with iOS 27. It has a side-button fingerprint sensor, an Apple N1 wireless chip, an Apple C2 cellular modem and second-generation Ultra Wideband, plus Emergency SOS and Crash Detection. It is rated IP68, and the titanium frame is paired with Ceramic Shield 2 on the front.
Who Should Consider This Phone?
Early adopters who want a large reading and multitasking screen that folds into a phone, and who already use Apple's ecosystem, are the main audience.
Who May Prefer Another Phone?
Buyers who want a lighter phone (254 g), a thinner folded body (11.3 mm) or a telephoto lens may prefer a Pro iPhone. Those on a tighter budget will find a $1,999 starting price high.
Editorial Verdict
The iPhone Duo brings Apple's chip, a 7.6-inch foldable display and 25W wireless charging into a titanium foldable. Its limits are its weight, folded thickness, price and lack of a telephoto camera. Because it has not shipped yet, hands-on results are not available.
