macOS 26.2 introduced the Edge Light feature for Macs with the M1 chip or newer, and recent code analysis suggests it may expand to the iPhone. According to pdfu, the iOS 27 Release Candidate contains evidence of Edge Light appearing on the iPhone Duo, though the color temperature setting is not yet fully implemented. On Mac, Edge Light acts as a virtual ring light, illuminating screen borders to evenly light the user’s face in low-light conditions.

Settings allow adjustments to line width and color temperature. A simulated video shows the feature functioning similarly on iPhone, with matching brightness and warmth controls. It remains unclear whether Edge Light will launch with the iPhone Duo on October 23 or later expand to other models.
