Apple unveiled its first folding iPhone, the iPhone Duo, at its autumn product event at Apple Park in Cupertino, California, on the 9th. It is the first folding-screen iPhone in the nineteen years since the original handset of 2007, and marks the company's formal entry into the foldable market.

The presentation was led by John Ternus, who took over as chief executive on 1 September. His predecessor, Tim Cook, appeared briefly on stage before handing over, and the livestream drew several hundred thousand concurrent viewers.

7.6 inches open, 5.4 inches closed

The Duo opens sideways in what is often called a passport format. Closed, the 5.4-inch outer display covers about ninety per cent of the screen area of a standard Pro model; opened, it becomes a 7.6-inch inner display. Apple said the device is the thinnest iPhone yet when unfolded.

The inner panel carries a nano-texture finish intended to cut glare. Demonstrations showed two applications side by side to compare shopping prices, or a video playing while a message is written.

Battery life for video playback was given as up to 31 hours on the inner screen and up to 44 hours on the outer one. The rear carries a 48-megapixel main camera and an ultra-wide lens of the same resolution.

The $1,999 threshold

Price is the largest variable. The Duo starts at $1,999 for 256GB, with storage options up to two terabytes. Pre-orders open on 16 October and sales begin on the 23rd.

The iPhone 18 Pro, announced the same day, was priced at $1,199 for 256GB and the Pro Max at $1,299, a rise of $100 over the previous generation and smaller than the increase many had expected before the event.

Set against rivals that have sold folding handsets for several years and have gradually lowered their price bands, Apple's entry point is high. The company did not give figures for initial production or target demand.

The first test of the Ternus era

The event was the first formal occasion at which an executive from hardware engineering took the front of the stage, after more than fourteen years under Tim Cook. The emphasis on specification detail was read alongside that background.

Component suppliers expect early production yields on the folding model, and the steadiness of hinge and display supply, to determine how the launch performs. Related component shares moved in both directions on the day.

A third view: what folds is the supply chain, not the screen

This paper takes the notable part of the announcement to be the rearrangement of the supply chain rather than the shape of the product. A folding structure depends at once on display panels, ultra-thin glass, hinge modules and dense batteries — fields long divided among firms in Korea, Taiwan, mainland China and Japan. A disruption in one place carries straight through to total shipments.

That is where the story matters for readers across Asia, including Chinese residents of Korea. Factory schedules in Incheon and Chongqing, Hsinchu and Hanoi are tied to a single release date, a reminder that this industry is organised by process step rather than by border.

Two things are worth watching. First, whether early supply after 23 October meets pre-order demand. Second, whether $1,999 acts as a ceiling or settles in as a new baseline. Both answers will appear as figures for the first time in the year-end results.
