Apple unveiled the iPhone Duo, its first foldable iPhone, with US pricing from
$1,999. The handset has a 7.6-inch internal display — the largest iPhone screen
to date — and a 5.4-inch external display whose area Apple says is roughly 90%
of the iPhone 18 Pro; both panels support ProMotion, always-on display and up to
3,000 nits peak outdoor brightness. The device uses a grade-5 titanium chassis
and a precision hinge of more than 100 components, carries an IP68 dust/water
rating, and integrates Touch ID into the side button. It is powered by a 2nm A20
Pro chip and a custom heat spreader; Apple says sustained performance is up to
35% higher than the iPhone 17 Pro and the phone supports split-screen operation
of two apps. Imaging includes 48MP main and 48MP ultrawide cameras; the fold
form factor enables using the rear cameras for selfies with external-screen live
preview. The phone uses a dual-battery architecture and, when using the outer
screen, supports up to 44 hours of video playback. Available in Starlight and
Midnight, storage options are 256GB, 512GB, 1TB and 2TB. US pre-orders begin
Oct. 16, on-sale Oct. 23; China and more than 70 other markets are in the
initial launch.
