Apple's long-rumored foldable becomes reality with the $2,000 iPhone Duo

Apple promises the phone, which has the same A20 Pro chip as the new flat phones, will still offer solid battery life. The inner display can play video for 31 hours, and the outer screen can do it for 44 hours. With mixed use of both screens, you can expect the iPhone Duo to last about 24 hours on a charge. The device has a titanium frame, something Apple briefly experimented with for its flat flagship phones, but this time it has added internal ceramic fibers for even more resilience. The added strength helps with the durability of a device you’re going to be opening and closing all day, but it will also probably make the device pretty heavy. Apple also notes that it has reinforced the antenna lines in the frame to reduce the possibility of failure. The titanium hinge contains more than 100 components to provide what Apple assures us is a smooth and reliable opening experience with “custom variable torque.” There are also magnets in the frame so the two halves snap together in a satisfying fashion when closed. The device is also IP68 rated for water and dust-resistance. Apple crows that the Duo is the thinnest iPhone ever when open, but that’s only true if you ignore the sizable camera plateau on the back. You won’t get the same camera experience as cheaper iPhones, though. In standard foldable fashion, Apple had to downgrade the cameras a bit. There are only two rear-facing sensors, a 48MP primary that lacks the adjustable aperture of the new iPhone 18 Pro, as well as a 12MP with 2x telephoto zoom. There’s a 12MP selfie camera in the outer display in addition to the under-display camera inside. A $2,000 phone is objectively very expensive, but Apple doesn’t just do expensive—it does lavishly, obscenely expensive. Remember the $3,500 Vision Pro, which cost several times more than competing VR headsets? Yet, the iPhone Duo is smack in the middle of high-end foldable pricing.
