How to disable automatic brightness on iPhone? Why does the brightness on the iPhone change on its own? Auto Brightness is a screen setting on iPhone and iPad that causes the device to automatically change the display brightness depending on the surrounding lighting conditions. For example, in the sun or in bright light, the screen adjusts and increases the brightness for better visibility, and in a poorly lit room or outdoors at night, the brightness decreases. This is how the brightness on the iPhone changes itself.
Auto-brightness in iOS can also extend battery life by adjusting the brightness on your iPhone or iPad based on the ambient light.
Some users turn off auto-brightness, while others leave it enabled on their iPad or iPhone. However, in iOS 11, auto-brightness was moved from the standard display settings to deeper iOS settings. This led some users to think that iOS 11 didn't have auto-brightness, but in reality it was just moved.
In this article we will tell you in detail how to adjust the brightness on any iPhone.
Reasons for random brightness changes
- The auto-brightness option is enabled - the device darkens when the processor is loaded, weather conditions change, or the type of room lighting. How to disable automatic brightness on the iPhone screen is described below.

- Mobile device overheating. When actively using the iPhone or when cases and accessories are incompatible, the phone becomes hot, which can lead to damage to the system. It is necessary to replace the protection or contact a workshop.
Why does the brightness on an iPhone change on its own?
Depending on the conditions of use, the owner of an iPhone needs different brightness. For example, in the Sun it is difficult to interact with a device that has a minimum threshold set. At night, on the contrary, the increased indicator only interferes.
The owner of an Apple iPhone can independently adjust the threshold, based on current conditions, but users often encounter a problem when the brightness level changes independently. He does not always adapt correctly to circumstances. For a second, the screen may light up too much, and the Sun may not respond to changing weather conditions.
Be that as it may, the change in backlight is not due to smartphone glitches. If the indicator constantly changes, this only indicates that the auto-brightness function is activated. In this mode, the backlight itself adapts to the environment, thanks to the built-in light sensor. It is on every iPhone, and therefore all owners of Apple devices encounter auto-brightness.

"Auto brightness" in settings

If there is no switch for auto-brightness in the specified sections, but there is a warning that the device’s battery life will be reduced, this indicates possible damage to the smartphone’s light sensor. This sensor informs the gadget about the level of illumination of the surrounding space. And based on these readings, the gadget decides to raise or increase the brightness of the display. If the sensor is not working, automatic brightness adjustment will not work. In this case, contact the service center.
As for moving the brightness adjustment function from its usual place. There is an opinion that Apple was unable to increase the battery capacity. Therefore, I decided to increase the operating time by complicating the process of increasing brightness manually.

Prefs:root=ACCESSIBILITY&path=DISPLAY_AND_TEXT - After that, click “ + ” and add a new action - “Internet” section - “ Open URL ”
