Overview
- Apple announced the iPhone Duo at its September 10 autumn event and set China preorders to start October 16 with sales from October 23.
- The Duo uses a 7.6‑inch inner and 5.4‑inch outer 120Hz display, runs on the A20 Pro chip, relies on eSIM only for global models, and includes a large VC vapor chamber for cooling.
- Apple built new fold‑aware camera features into the Duo, including Smart Take that uses on‑device AI to auto‑capture group shots, Kid Cue to attract children’s attention, Duo Preview for external‑screen framing, and Duo FaceTime to let people join calls on the outer display.
- The phone’s imaging hardware is a dual‑fusion two‑camera system with two 48MP sensors and a 2x optical zoom limit, and it omits several iPhone 18 Pro features such as a telephoto lens, ProRAW/ProRes capture, and sensor‑shift optical stabilization.
- Early reports say the Duo will not support WeChat’s tablet‑mode dual‑login and will lack several multi‑screen app behaviors at launch, a gap that matters in China as separate coverage shows very strong initial sales for Apple’s iPhone 18 Pro models and signals pressure on developers to adapt.
