The screen brightness on your smartphone is one of the largest contributing factors to the amount of battery life that you get.
It takes a lot of power to keep a bright screen, even on efficient modern smartphones.
While keeping your screen dim may seem like the obvious solution, it’s not always practical. A dim screen may be difficult to view, and even impossible in some environments.
Your Google Pixel 4A has a setting called Adaptive Brightness that can be very useful for this purpose. It can learn from your brightness preferences about when and where to make the screen bright or dim, plus it uses its own information about the environment to manage things.
You can toggle adaptive brightness on or off for your Pixel 4A by going to Settings > Display > Adaptive brightness > and turning the toggle switch on or off.
Our tutorial continues below with additional information on the screen brightness management option on the Android 11 Pixel phone.
How to Change the Pixel 4A Adaptive Brightness Setting

More Information on Adaptive Brightness and What it Does in Android 11 on a Pixel 4A
If you elect not to enable the adaptive brightness setting then you can still manage the screen brightness manually.
The screen brightness option can be found by swiping down from the top of the screen and pulling down on the handle. You will see the brightness slider at the top of the menu, where you can drag it to the left to make the screen dimmer, or drag it right to make the screen brighter.
If you have adaptive brightness enabled the brightness slider is still there, it just ties into the adaptive brightness’s “learning” so that it can see what your screen brightness preferences are.
While you may initially not like the adaptive brightness option, it will improve over time as it sees the brightness levels that you like during certain times of the day and in various environments.
Effective management of screen brightness is one of the best ways to make your battery last longer, so minimizing the amount of time that your screen is very bright will be helpful in the long run if you find that you often run into issues with battery life.
