iPhone Screen Keeps Dimming With Auto-Brightness Off

The issue of the iPhone screen brightness keeps changing even with auto-brightness turned off can be perplexing. You might wonder why your device continues to adjust its brightness without your input. In this scenario, it’s essential to delve into the potential causes of this erratic behavior.

The iPhone screen brightness keeps changing because of a feature known as True Tone. This function alters the color temperature of your display to match the ambient lighting conditions. Even when auto-brightness is disabled, True Tone may still be active, causing your screen to appear dimmer or brighter depending on your surroundings. To regain full control over your screen’s brightness, you can disable True Tone in your iPhone’s Display & Brightness settings.

Software-related factors could contribute to the iPhone screen brightness fluctuations. Glitches in the iOS or conflicts with certain applications may lead to unwanted changes in screen brightness. To address this, you can attempt to resolve the issue by restarting your device, ensuring your iOS is up to date, and identifying and removing any problematic apps that could be causing interference.

How to Prevent Your iPhone From Dimming Screen Brightness

If you’ve been wondering, “Why does my brightness keep going down?” on your iPhone and want to prevent it from dimming the screen brightness automatically, there are several steps you can take to regain control over your device’s display settings.

Turn Off Auto-Brightness: The first step is to ensure that the Auto-Brightness feature is turned off. To do this, go to “Settings,” then “Display & Brightness,” and toggle off the “Auto-Brightness” option.
