macOS 26.2 added an Edge Light feature to Macs with the M1 chip or newer, and it has now been rumored that this feature will expand to the iPhone.

According to pdfu, who has been digging through code in Apple's software updates in recent weeks, the iOS 27 Release Candidate contains evidence of the Edge Light feature coming to the iPhone Duo at a minimum. However, it appears that the feature is still in development, as they said the color temperature setting is not fully implemented.

On the Mac, Edge Light illuminates the borders of the screen to evenly illuminate your face in low-light conditions. The feature is essentially a virtual ring light, and there are settings to adjust the width of the white line around the screen and a color temperature slider to make the light it produces appear more or less warm.> Edge Light is coming to iPhone.

Based on a video of the feature in action on a simulated iPhone, it appears that the feature will work in a similar manner and have the same brightness and color temperature settings on the iPhone. It is unclear if Edge Light will be available on the iPhone Duo when the device launches on October 23, or if it will expand to other iPhone models.

Some of pdfu's other Apple-related code findings have already proven to be right, so the user has an accurate track record so far.Related Roundups: iOS 27, iPadOS 27, iPhone DuoTag: pdfuRelated Forums: iOS 27, iPhone
