How to stop iPhone from dimming?

You may find your iPhone’s brightness is dimming for the following reasons. These are the most common reasons for dimming.

How do I stop my iPhone’s automatic dimming?

Getting full manual control over the brightness of your iPhone screen begins with disabling Auto-Brightness. You can disable automatic screen brightness adjustment on your iPhone by disabling that setting. You must also disable Night Shift if you want total control.

Note: iPhone users can save battery by reducing screen brightness. It’s possible that your iPhone will need to be charged more often if you disable auto-brightness.

On an iPhone, you can disable Auto-Brightness as follows:

  • Go to Settings.
  • The list of settings can be scrolled down by tapping and dragging.
  • Click Accessibility

  • Touch Display & Text Size.
  • Turn off Auto-Brightness by tapping the toggle.
  • As a result, your iPhone’s brightness will not be affected by ambient light conditions.

How to turn off iPhone Night Shift? 

Along with the Auto-Brightness feature, the Night Shift feature can also be used to reduce iPhone display brightness. You will need to adjust the display yourself using the Control Center if you disable both Auto-Brightness and this feature.

Here’s how to disable Night Shift on an iPhone:

  • Open the Settings menu.

  • Then tap Display & Brightness.

  • Select Night Shift.

  • By tapping the Scheduled toggle, you can turn it off.
  • After turning off Night Shift, your display will no longer be adjusted at night. Tap Back to confirm the switch is off.

How to Manually Adjust iPhone Brightness?

You will no longer be able to control the brightness of your iPhone based on light conditions and time of day if you turn off Auto-Brightness and Night Shift. It may be difficult to see in bright sunlight after making these changes, or the display may be too bright at night. If you do, you will have to adjust the brightness manually whenever you want the display to be brighter or when it seems to be too bright.

You can adjust iPhone display brightness by following these steps:

  • Launch the Control Center.

Note: Tap the bottom right corner of the screen, or tap the top right corner of the screen, depending on your iPhone.

  • To decrease the brightness, slide your finger downward.
  • You can increase the brightness by sliding your finger up.

How Come My iPhone Keeps Lowering the Brightness?

According to the current conditions, the brightness of your iPhone automatically changes throughout the day. Either of these features could be causing your phone to dim its brightness based on the lighting conditions and the time of day. When your battery is about to run out, your phone enters the low-power mode.

The following features allow you to lower the brightness of an iPhone:

1. Auto-Brightness

With this feature, the screen brightness is automatically matched to your environment based on the light sensor in your iPhone. You can set your display to be brighter if you’re in a brightly lit environment. Dimming your display will make it appear brighter. Your eyes will feel less fatigued.

2. Night Shift feature

The Night Shift feature adjusts the brightness and color temperature of your iPhone screen in accordance with the time and location of the day. In the evening, screen temperatures will shift and brightness will reduce at sunset to reduce eye strain.

3. Low power mode

A low power mode is activated when the battery drops below a critical level. The Low Power Mode lowers the screen brightness in order to increase battery life. This mode can be turned off in battery settings, or your phone can be charged while plugged in.

Your iPhone is still dimming!

However, even after you turn off Auto-Brightness and Night Shift, your iPhone could still be dimmer. It is possible that your iPhone is dimming because of a software or hardware problem.

Follow the steps below to find out how to troubleshoot your iPhone’s software and find a repair option if it is damaged!

You should restart your iPhone

If your iPhone display is dimming due to minor software problems, restarting is a common solution. Here are instructions depending on your iPhone model:

When an iPhone without Face ID is used, hold down the power button until the “slide to turn off” button appears. You can then shut down your iPhone by swiping from left to right the red power icon. Once the Apple logo appears directly on the center of your iPhone screen, press and holds the power button again.

If you have an iPhone with Face ID: hold down both volume buttons simultaneously until you see “slide to power off” on the display. To turn off the computer, swipe from left to right across the red power icon. Once your iPhone X or newer is back on, wait a few moments before pressing the side button again.

Make sure your iPhone is updated

New iPhone features and bug fixes are regularly added to the iPhone software through regular updates. Select General -> Software Update from the Settings menu. When an update is available, tap Download and Install.

Ensure that Auto-Brightness is turned off in Settings -> Accessibility -> Display & Text Size after the update is completed. Occasionally, this feature will be reactivated after updating iOS!
