iPhone Duo teardown reveals dual batteries and glossy crease under matte film

Kingmi Mobile tore down an iPhone Duo before units ship, showing two separate batteries in each half of the chassis and a glossy inner screen with a more visible crease once the matte film is peeled off. Battery replacement requires removing the back panel and outer display, while inner display repairs cost about $999 and hinge-area damage up to $1,499.

• Matte film peels off to reveal a glossy inner screen with a clearer crease
• Dual batteries sit in each half; replacement needs back panel and display removal
• Cameras and mainboard are standalone modules; hinge and display are not
• Inner display repair about $999, hinge-area damage up to $1,499
