iPhone Duo Review: Apple's $1,999 Foldable Weighs Design Against Usability

The Duo, Apple's inaugural folding iPhone, is priced at $1,999, making it the priciest iPhone to date. According to a PetaPixel review, it boasts a Grade 5 titanium frame, a Ceramic Shield 2 front display, and a custom alloy hinge, which is rated slightly higher than the Samsung Galaxy Fold. The matte interior display minimizes glare, and the crease is almost imperceptible. Touch ID has replaced Face ID, a change the reviewer considers a misstep due to its sluggishness and registration problems. Battery performance is just sufficient, dipping below 30% after a long day. The camera system features two 48-megapixel sensors but lacks ProRAW. One-handed operation feels cumbersome, and older applications do not display well. Ultimately, it represents a blend of iPhone and iPad.
