iPhone Duo
Apple's first foldable pairs a 7.6-inch inner display with a fully usable 5.4-inch cover screen, a grade-5 titanium frame, IP68 resistance, and the same A20 Pro chip as the 18 Pro, but it starts at $1,999 with no independent battery-capacity or benchmark data yet.
Pros
- 7.6-inch nano-texture inner display minimizes crease visibility, alongside a genuinely usable 5.4-inch cover screen
- Grade-5 titanium frame, Ceramic Shield 2, and IP68 dust/water resistance - firsts for an Apple foldable
- A20 Pro with a dual-battery architecture and vapor chamber for all-day use across both displays
- Apple Pencil (USB-C) support and a Touch ID side button add flexibility no other iPhone offers
- 48MP Fusion Main and 48MP Ultra Wide cameras with an optical-quality 2x zoom crop
Cons
- Starts at $1,999 for 256GB, rising to $3,199 for 2TB
- No separate telephoto lens - just a digital 2x crop from the main sensor
- Battery capacity in mAh and independent benchmark scores are still unconfirmed ahead of the October 23 launch
- Touch ID replaces Face ID, a step back in biometric convenience for Face-ID-accustomed users
Very good
