Summary
  • Apple introduced the iPhone Duo as its first book‑style foldable device
  • Apple said the Duo has a 7.6‑inch inner and 5.4‑inch outer display
  • iPhone Duo returns side Touch ID and uses dual batteries operating as one
  • Apple highlighted A20 Pro chips, better cooling and on‑device Apple Intelligence

Apple unveiled its first foldable phone, the iPhone Duo, at a company keynote led by the new CEO John Ternus, who framed the device as a careful reimagining of the smartphone form factor. Apple described a book‑style handset that opens into a wide inner display and closes to a compact outer screen.

Apple said the iPhone Duo uses an inner flexible display measuring 7.6 inches diagonally and an outer screen roughly the size of a Pro model at about 5.4 inches. The company said the frame is made from Grade 5 titanium and that an array of magnets provides a secure closure.

Apple highlighted hinge engineering intended to reduce visible creasing and a side‑mounted Touch ID button for biometric access. The company said the phone uses two batteries that operate as one and estimated battery life in different usage modes, with longer runtimes on the outer screen and robust video playback on the inner display.

Apple set a base price at roughly two thousand dollars for the iPhone Duo and said preorders would start before retail availability. The handset will launch in two finishes described by Apple as star white and night sky.

Implications And Related Announcements

Apple demonstrated software updates that adapt iOS to the Duo’s wider canvas, showing side‑by‑side apps and split‑view multitasking. Craig Federighi said developers can scale content to the larger display and launch multiple windows of the same app for comparison tasks.

Alongside the Duo, Apple showcased the iPhone 18 Pro line as the steadier upgrade option. Reporting and Apple commentary linked the Pro models to a new A20 Pro‑class chip, improved thermal management including a vapor chamber, and a mechanical variable‑aperture camera for optical control over depth of field.

Apple also said Apple Intelligence will run on devices locally with iOS updates and on the latest watch and AirPods models, promising faster on‑device voice transcription and cross‑app actions. Some coverage noted concern over Apple replacing Face ID with side Touch ID, warning it could affect users who rely on facial biometric workflows, especially for quick payments in certain markets.

Industry reaction was mixed. Analysts and media urged buyers to wait before purchasing first‑generation foldables so hinge durability and app adaptation can be independently tested. Market response during the event reflected measured investor sentiment, according to reporting on trading that day.
