The Usual Suspects (and Why They Might Not Be the Culprit)

Apple often points to a few common settings when this issue arises:

  • Auto-Brightness: This feature automatically adjusts your screen brightness based on the ambient light While helpful in most situations, it can sometimes misinterpret bright sunlight and dim the screen unnecessarily.
  • True Tone: This feature adjusts the color temperature of your screen to match the ambient light. While it can make the screen easier on the eyes, it can also contribute to dimming in sunlight.
  • Overheating: iPhones, like all electronic devices, can overheat in direct sunlight. To protect itself, your iPhone may dim the screen to reduce heat generation.

But here’s the thing: Many users, like those in the Apple forum you linked, have already ruled out these factors. They’ve turned off Auto-Brightness, and True Tone, and ensured their phones aren’t overheating, yet the problem persists. This leads many to believe it’s a software bug, possibly related to how the iPhone’s sensors interpret bright sunlight.
