11 Ways To Fix iPhone Screen Dimming (Including auto-brightness off)

Is your iPhone screen dimming even you turn off the auto-brightness? If so, then this post is for you. There are a few possible reasons why your phone can do this and we will talk about them in-depth to help determine the root cause of the problem.

1) Turn Off Auto Brightness

The first thing to try turning off the auto-brightness feature. Go into “Settings” > “General” > “Accessibility” and then tap on the slider next to Auto-Brightness so that it turns white instead of green, which will disable this feature.

2) Disable TrueTone

TrueTone is a feature that adjusts the color and intensity of your screen based on ambient light. If this setting has been turned on, it may be causing the dimming issue by continuously adjusting to different lighting conditions which will make the iPhone’s own brightness control seem slow or inaccurate. To disable this go into “Settings” > “General” > “Accessibility” and then tap on the slider next to ‘True Tone’ so that it turns white instead of green, which will disable this feature.

Another way you can try disabling TrueTone is through Control Center: swipe up from below your display with two fingers (or slide two fingers across in any direction) and tap again anywhere about one second after you see the screen flash.

*Note: If you don’t have it on already, swipe up from below your display with two fingers (or slide two fingers across in any direction) and tap again anywhere about one second after you see the words “Screen Flash.” This will allow for a dim-light mode that may prevent auto-brightness issues as well as save some battery power at night time when using low light.

3) Disable Night Shift Feature

Some iPhone users have reported an issue where their screen dims when using the Night Shift feature. This may be because it is automatically turning on at night time while you are sleeping, which can adversely affect your sleep cycle if you use this feature frequently. To disable this go into “Settings” > “General” > “Accessibility” and then tap on the slider next to ‘Night Shift’ so that it turns white instead of green, which will disable this feature.

4) Turn Off Low-Light Zoom Filter

A low-light Zoom filter is another iPhone screen dimming feature when using auto-brightness. Turning the iPhone’s low-light zoom filter off will prevent your iPhone from brightening or darkening the display according to ambient lighting conditions. However, turning this setting may reduce image quality in some apps like Instagram and Snapchat if you use zoom frequently while recording videos or taking pictures with these apps. To turn off this function go to Settings > General > Accessibility Scroll down until you find the Zoom section then toggle the Low light zooming option Off. Finally, tap on Zoom Filter On/Off button on the Display Accommodations settings page so it becomes grayed out indicating that change is made successfully.

5) Disable Low Power Mode

Power Mode disables your iPhone from showing distractions and notifications. When this mode is enabled, it dims the screen brightness to save battery power. In case you’re experiencing frequent dimming of display with auto-brightness turned on then switch off Low Power Mode or adjust its settings by navigating to Settings > Battery Scroll down until you find the Low Power Mode section then toggle off this feature.

6) iPhone Overheating Issue

If you’re experiencing issues with your iphone screen dimming, and the steps mentioned above haven’t solved this problem for you, it might be time to check if there is an issue with overheating.

If your iPhone is overheating, you will find out when the phone switches off on its own without warning and it gets extremely hot to the touch. You may also notice that apps are crashing or taking longer than usual time to load up.

7) Restart iPhone

If your iPhone screen dimming is due to overheating, you may be able to solve the problem by restarting your iPhone.

8) Increase Auto-Lock Time

If restarting your iPhone doesn’t help, the next thing you should try is to increase the auto-lock time

In case you’re not sure how to increase the auto-lock time, here is a quick summary Go to ‘Settings’ and click on the ‘General’ option. Tap on ‘Auto-Lock’

From the ‘Auto-Lock’ menu, select a time period for the iPhone to remain on after it has been used, Once you’ve selected a time period, click on the ‘Settings’ button to save your changes. The iPhone will automatically lock after it

9) Update iPhone

Apple releases updates to fix bugs and improve performance. Update your iPhone by going to “Settings”, then select “General”, followed by “Software update”. Make sure you have at least 50% battery life before updating so that it doesn’t shut down unexpectedly during the process.

10) Reset your phone

In order to reset your iPhone, select ‘Settings’. Then, choose ‘General’ and ‘Reset’. After selecting the option to reset your phone, it will take a few minutes for all of your data to be deleted from the iPhone memory before restoring itself back to factory settings. This step is optional.

11) Contact Apple Store

If none of these solutions work, it may be time for you to consider taking the issue up with the professionals at an Apple store near you. If they find that there is a hardware problem with your phone, they will either recommend replacing or fixing it.
