Fixing your iPhone ambient light sensor is the perfect solution. But how do you go about that? is the question we want to answer right here in this article. So continue reading!
Why Does My iPhone’s Brightness Keep Dimming?
Your iPhone keeps dimming mainly because of the following reasons:

- Low Power Mode: The low power mode feature is designed to help you maintain your device’s battery life by limiting the background operations. Enabling this feature dims your iPhone brightness automatically.
- Low Battery: Are you running your iPhone on low battery? If so, you should expect your device’s brightness to dim. The reason is that there is not enough battery power to maintain your iPhone brightness.
- Night Shift: Here is another reason why your iPhone brightness keeps dimming. Night shift is structured to dim the blue light emitted from your screen, shifting it to a warmer orangish tint.
- True Tone: Enabling the true tone feature on your iPhone also dims the screen brightness.
