Hi VinsApple,

I understand that the brightness of your iPhone screen seems to change after it has been on for a few minutes. I'm happy to provide some information to help with this.

Since it seems to change, check to see if Auto-Brightness is enabled:

Adjust the display settings on your iPhone, iPad, or iPod touch - Apple Support

Set brightness or use Auto-Brightness

To adjust brightness, use Control Center. You can also do this from Settings, where you can find extra options like Auto-Brightness:

Go to Settings > Display & Brightness.

Drag the slider to the right or left.

If your iOS device has an ambient-light sensor, you’ll see an Auto-Brightness setting under the slider. Auto-Brightness uses a light sensor to adjust brightness based on your surroundings. This setting can sometimes improve battery life.

If you want to raise or lower the Auto-Brightness levels, you can customize the setting:

Go to Settings > Display & Brightness and turn on Auto-Brightness. The brightness slider moves according to the lighting conditions.

Use the slider to adjust the Auto-Brightness setting.

If Auto-Brightness isn’t working as expected, reset it. Go to Settings > Display & Brightness and turn off Auto-Brightness. Then turn it on again.

Thanks for using the Apple Support Communities. Cheers!
