Auto-brightness is one of those functions that works through the roof on any smartphone. Unfortunately, the iPhone did not escape this fate: the smartphone does not always correctly adjust the display brightness .

Not long ago, in our Telegram chat, a reader complained that auto-brightness did not work . At first glance, this is a reason to immediately contact the service center. There is no need to rush: sometimes you can really solve the problem yourself. We have prepared some useful tips for you on setting auto brightness on iPhone .
We tell you how to set up Auto Brightness on iPhone
Features of adjusting the display brightness level
Before talking about the process of choosing the brightness level of a cell phone, it is worth talking about the features. Manufacturers in new versions of the software have provided the ability to automatically change screen saturation. When the owner is in a dark room, the smartphone becomes darker. If the user is currently using the gadget in a well-lit room or on the street, the gadget itself makes the colors more saturated. This allows you to avoid fiddling with the settings manually.

- The new version of iOS includes an additional Dark Theme option. It allows you to remove the white screen and change it to black on your iPhone. Many cell phone owners appreciate the feature and use it.
Why does my iPhone screen keep dimming?
Your iPhone can dim its screen to save battery power. This is normal. But for most users, the main reason for an unusually dark iPhone screen is an accessibility feature called Reduce White Point. When this setting is enabled, the intensity of bright colors is greatly reduced, resulting in a dull iPhone screen.
Other reasons could include auto-brightness not working, a bug in iOS, zoom being enabled, a faulty iPhone screen, and more. But before moving on, consider the following main points that may be causing the problem.
Are you using a screen protector that darkens your display?
Several protective films (low-quality or matte) reduce brightness. If you use it, consider removing it or using a better screen protector. Same thing with the plastic lamination/screen protector.
Are you using a third party display?
Have you ever replaced your broken iPhone display on the cheap from an unreliable, unreputable or unauthorized service center? If so, they may have used a low-quality display that wasn't very bright.
In this situation, you can get a better screen by sending your phone to an Apple authorized repair shop, or at least one that is well-known and has good reviews. Talk to your friends about it or look for a local repair shop with good reviews.
Does the application reduce the screen brightness?
Are you using a video, photo, or game app that manually dims the screen brightness while you're inside it? If so, take a moment to explore the app's settings and be sure to turn off any screen brightness or customization options.

How to configure manually through Control Center
If a customer wants to make the screen brighter or darker, all they need is Control Center on their smartphone. In this case, there is no need to go to the settings section. But it is also impossible to activate additional services through such a panel. The operation is performed according to the following scheme:

How to activate the Auto Brightness option on iPhone
If the user is interested in how to make the brightness on his iPhone even lower, he can use the automatic setting. Before the release of iOS 11, the client could perform the procedure using the control panel, but the operation was performed manually. When the company provided version 11 software, the item was moved to the “Universal Access” section. The user must find the desired section in the smartphone and then open it. Next, select the desired subsection and activate the “Auto-Brightness” option. Immediately after turning on the function, the phone will adapt to the lighting in the room.
Disable Zoom to Fix iPhone Screen Dim and Dark

How to deactivate the “Auto Brightness” option on a smartphone
After the release of version 11 of the software, the automatic setup feature is enabled on the phone by default. It works in the same mode on iOS 12. Despite the automatic process, the user can independently adjust the screen saturation level in the control center. But as soon as the situation changes, the phone itself will adjust the necessary parameters.
There are situations when auto-tuning does not work properly or the user prefers to select the parameters independently. In this case, it is possible to deactivate “Auto Brightness”. The operation is performed according to the following scheme:
- the smartphone needs to be unlocked;
- on the main screen you should find the “Settings” gear icon;

- now the client selects the “Universal Access” section;
- after the transition, several items will be displayed on the screen”;
- the owner clicks on the title “Display and text size”;

To deactivate the function, you simply need to move the slider to the “Off” position. After this, auto-brightness will not change the screen saturation automatically.
Restart iPhone to Stop iPhone Screen from Dimming
The first solution you can use to fix your iPhone's dark screen is to restart your device. This can be considered as the easiest way to help you solve many iOS system problems.
To restart your iPhone, you can press and hold the Power button until you see the option to ask you to turn it off. Then drag the slider to turn off your iPhone. After a few seconds, you can turn on your device in the same way.
You can also press and hold the Home and Power button until you see the Apple logo showing on the screen. When you open your iPhone, you can check the brightness of your iPhone screen.
Different iPhones have different restart settings. You can check the details here: How to restart iPhone.
For what reasons may the display brightness decrease?
Turning on Auto Brightness mode can make the screen on the user's iPhone darker. This option independently controls the level of lighting in the room. This allows the smartphone to select the desired level of color saturation without outside help. This function makes it possible to optimize the load on the processor and make using the smartphone comfortable. But there are also other reasons why the brightness level drops:
- The smartphone battery is damaged or discharged. The display becomes darker when the smartphone's battery runs out. If the phone does not indicate that the battery is low, it means it is damaged. It is recommended to contact a service center to check the battery operation. If the battery is working properly, the problem may be an OS failure. In this case, it is recommended to reinstall it.
- The smartphone is overheating. When your iPhone gets too hot, its display becomes less bright. This is provided by automatic settings to reduce the load on the processor. Thus, the phone independently prevents overheating. To solve the problem, it is recommended to remove the used case from the smartphone. Users should only use cases from Apple to avoid encountering an unpleasant situation.
If the gadget owner needs to adjust the brightness level of the smartphone, he can use the “Settings” section or go to “Control Center”. The phone also has “Auto Brightness” and “Dark Theme”.
Why did Apple hide auto-brightness settings?
The main reason is to save battery power in the iPhone. For this purpose, even in the menu itself there is a special warning message “Turning off auto brightness can reduce battery life.” Well, and so that users who are thinking of removing automatic brightness on the iPhone do not immediately get to it.
In addition, the auto-brightness function in the current iOS 13.1 is implemented quite intelligently. Although there is a slider for adjustment, it does not set a fixed level of display brightness, but only determines the limits within which it can change. Even if you set the brightness to the minimum level, the information on the display remains readable in sunlight.
The function is generally necessary. However, sometimes, for example, when you are watching a long video, it can be inconvenient. Changing the screen brightness will only get in the way. And in this case, you already know how to turn off automatic brightness on an iPhone.
What is the True Tone feature?
To operate True Tone technology, a system of multi-channel sensors is used. With their help, the device adjusts the color temperature of the screen so that the image looks as natural as possible under environmental conditions. On a winter day, the screen will be colder outside, and in the evening, with indoor lighting, it will be warmer.

3. “Warm” picture depending on lighting
Apple's most advanced feature for adapting the color temperature of the display is the True Tone (Settings - Display and Brightness - True Tone). It is available only on iPhone X, iPhone 8/8 Plus, iPad Pro (except for the 12.9″ 1st generation model).
Thanks to the presence of a special sensor, the device independently evaluates the ambient light and adjusts the color temperature of the screen to the ambient lighting. I went into a room with yellow lamps - the screen also turned yellow, went out into the sunlight - the screen turned white.
This allows the user to always see the most comfortable picture for perception.
True Tone can be turned on and off in the same way as Night Shift: open the Control Panel, hold down the brightness slider and click on the corresponding button.
