What is the price and release date of the iPhone Duo?

The iPhone Duo starts at $1,999 for the 256GB base tier. Pre-orders open globally on Friday, October 16, 2026, and customer deliveries alongside retail availability start on Friday, October 23, 2026.

Why does the iPhone Duo use Touch ID instead of Face ID?

Engineering constraints in the ultra-thin 4.8mm unfolded chassis left insufficient vertical depth to house Apple’s dot projector and infrared TrueDepth camera module on the inner display. Apple instead engineered an ultra-fast capacitive Touch ID sensor into the sapphire-glass power button on the upper-right spine.

What are the main upgrades on the iPhone 18 Pro and Pro Max?

The iPhone 18 Pro family features the 2nm A20 Pro application processor, a triple 48-megapixel camera system (wide, ultrawide, and 5x telephoto), 65W fast wired charging hitting 50% capacity in 15 minutes, and up to 30 hours of continuous video battery life on the Pro Max.

How does Live Rewind work on Apple Watch Series 12 and Ultra 4?

Live Rewind maintains a circular 15-second audio buffer in volatile SRAM memory within the S12 processor. When a wearer double-presses the Digital Crown, an on-device quantized acoustic model transcribes the dialogue and displays an instant recap text on screen. The audio never touches persistent NAND flash or external cloud servers.

What are the left-handed grip concerns on the iPhone Duo?

Left-handed users noted that holding the unfolded 7.6-inch device in the left hand places their fingers directly over the hinge spine, forcing their thumb to reach across the entire display width to access right-mounted power, volume, and Camera Control keys. Apple has not yet announced a software display inversion mode for left-handed ergonomics.
