The new foldable requires separate purchases for a stylus and fast charger to reach its full capabilities.

249 dollars. That is the cost of two specific accessories needed to unlock the headline features of Apple’s new iPhone Duo. The device launched on October 23, 2026, as the company's first foldable smartphone. It ships without the stylus or power adapter required for its most advertised functions.
Apple Pencil support is the first major feature. Users can write notes and sketch on both the outer and inner displays. Apple stated the design uses the proportions of a standard A-series paper notebook. This capability arrives in the iOS 27.2 update next week. Only the Apple Pencil (USB-C) is compatible. It is currently listed at $69, down from $79.
Fast charging is the second requirement. The phone reaches 50 percent charge in about 20 minutes. This speed requires a specific power adapter. The box includes a USB-C cable but no charger. Tech site 9to5Mac recommends Apple's 40W Dynamic Power Adapter with 60W Max. That unit costs $34, down from $39. Anker’s 100W USB-C charger is an alternative at $29.
Drivers will need a mount to use the device for navigation. ESR’s MagSafe Car Mount clips to an air vent and holds the phone magnetically. It is priced at $19, down from $29. The writer notes that CarPlay allows maps to display on the car screen while the phone shows step-by-step directions. They expect this setup to perform better on the Duo's larger display.
Cases and security cameras round out the recommended list. Third-party cases include the SPIDERCASE Magnetic Case at $29 and the Spigen Ultra Hybrid Pro at $39. Apple sells its own Folio with Kickstand for $129 and a standard case for $79. For home security, the Aqara G100 2K camera costs $39, and a eufy 4K camera is $69.
The device also upgrades StandBy mode. It displays various views when standing upright, even if not charging. Two views, Home Camera and Home Modular, provide access to smart home accessories. These features allow users to check security cameras at a glance. AirPods Pro 3 are also suggested for those without current earbuds. They are on sale at Amazon for $199, down from $249.
