Why does my iPhone screen get brighter by itself?
One of the reasons why your iPhone screen gets brighter by itself is due to a feature called Auto-Brightness. This feature was introduced in iOS 11 and is designed to automatically adjust the brightness of your screen based on the ambient lighting in the room you’re in.
The Auto-Brightness feature works by utilizing the sensors on your iPhone. These sensors can detect the level of light in your surroundings and adjust the brightness of the screen accordingly. For example, if you are in a brightly lit room, the screen brightness will increase to make it easier for you to see and interact with your device. On the other hand, if you are in a dark environment, the screen brightness will decrease to prevent eye strain and conserve battery life.
The purpose of Auto-Brightness is to provide you with an optimal viewing experience regardless of the lighting conditions around you. It ensures that your screen is neither too bright nor too dim, allowing you to comfortably use your iPhone in various environments.
By automatically adjusting the screen brightness, Auto-Brightness also helps to conserve battery life. Since the brightness is adjusted based on the ambient lighting, the screen doesn’t need to be at maximum brightness all the time, thus saving power.
While Auto-Brightness is generally a useful feature, there may be times when you prefer to manually control the brightness of your screen. In such cases, you can disable Auto-Brightness by going to the Settings app on your iPhone, selecting Display & Brightness, and toggling off the Auto-Brightness option.
It’s worth noting that the Auto-Brightness feature is not perfect and may not always accurately adjust the screen brightness to your liking. For instance, in some situations, you may find the screen to be too dim or too bright even with Auto-Brightness enabled. In these cases, you can manually adjust the brightness using the Control Center or the Settings app.
The Auto-Brightness feature on your iPhone is designed to automatically adjust the screen brightness based on the ambient lighting in your surroundings. It provides you with an optimal viewing experience and helps conserve battery life. While it may not always be accurate, you have the option to manually control the screen brightness if desired.
