Apple’s Edge Light feature might not stay a Mac exclusive much longer. As per a report from MacRumors via pdfu on X, the release candidate version of iOS 27 released earlier this week contains code pointing to Edge Light arriving on the iPhone Duo, at least. The feature appears to still be under active development, though, since the color temperature setting reportedly isn’t fully functional yet in the current code.
Apple originally introduced Edge Light on the Mac through macOS 26.2, limiting it to machines running an M1 chip or newer. The feature works like a built-in ring light, brightening the edges of the screen to evenly illuminate someone’s face during video calls in dim lighting. Mac users can already adjust two things: the width of the glowing border around the screen, and a color temperature slider that shifts the light’s warmth up or down depending on preference.
A video showing the feature running on a simulated iPhone suggests Apple plans to bring over the same basic functionality, including matching brightness and color temperature controls. That would essentially port the Mac experience over to iPhone with minimal changes to how it actually works, just applied to a much smaller screen.
Plenty of details remain unclear at this stage. There’s no confirmation yet on whether Edge Light will be ready in time for the iPhone Duo’s October 23 launch, or whether it might arrive later through a software update instead. It’s also uncertain whether Apple plans to limit the feature to the iPhone Duo specifically, or eventually roll it out to other iPhone models further down the line.
Worth noting, pdfu isn’t a first-time source on Apple code discoveries. Several previous findings from the same account have turned out to be accurate, giving this particular leak a bit more weight than a typical unconfirmed rumor might otherwise carry.
