Struggling with iPhone’s Auto-Brightness? Try These 7 Methods to Restore Functionality

Auto-brightness ensures your iPhone’s screen brightness levels adapt automatically according to the light around you. For example, when you step out in the sun, the brightness increases. And inside a room, it decreases. When your iPhone’s auto-brightness feature doesn’t work, it can spoil your user experience and even consume more battery.

If auto-brightness isn’t working on your iPhone, you can use these solutions to fix it. Once that’s done, it should be more comfortable to use your iPhone during the day, night, and any other times.

1. Clean Your iPhone’s Notch Area

The ambient light sensor is at the top of your iPhone screen. Body oils, sweat, and other such gunk may stick to this sensor when holding the phone to your ear during long calls. Due to this, it may stop your iPhone’s ambient light sensor working, which is what’s responsible for adjusting the screen brightness according to your surroundings.

To fix this, use a clean, dry cloth to wipe the top portion of your iPhone screen. After this, auto-brightness should work fine. If not, follow the remaining solutions below.

6. Remove Any Thick Screen Protectors

Are you using an abnormally thick screen protector on your iPhone? If yes, it may cause problems with the smooth working of the ambient light sensor. To address this, consider removing your screen protector. If you must use one, opt for a screen protector that’s thinner, or medium thickness, instead.

Similarly, if you have a case that covers the entire front of the device, or even partially blocks the top sensor area, remove that as well.

7. Reset All Settings

When you reset all settings, personal data like downloaded apps, music, photos, videos, and such won’t be deleted. However, all the settings you have customized to your liking will reset and return to the default options. This includes Wi-Fi, Bluetooth, VPN configurations, Home Screen layout, keyboard settings, and more.

After you reset all your settings, several problems such as auto-brightness not functioning should be fixed. Here’s how to do it:

OpenSettings and tapGeneral .
TapTransfer or Reset iPhone .
TapReset and chooseReset All Settings .
Enter your device passcode to confirm.
