Like people, used laptops will show signs of age over time, with one of the most common problems users encounter being battery life, even with laptops that aren't too old. Many people often think that the CPU is the main reason for the battery draining quickly, but that's not actually the case.

According to an independent study from Jacksonville University (USA), the screen is actually the most power-consuming component of a laptop. Specifically, when the screen is set to 100% brightness, it only takes 815 seconds, or about 13 minutes, to drain 5% of the battery. Even when the brightness is reduced to 70%, this time only lasts for 20 minutes. This shows that adjusting screen brightness is one of the effective ways to save battery life on laptops, especially older models.
Ways to increase laptop battery life besides reducing screen brightness.
In addition to adjusting brightness, users should also pay attention to their laptop usage habits. Letting the battery completely drain or obstructing airflow by placing the laptop on your lap can reduce battery performance over time. For optimal laptop performance, users need to ensure sufficient airflow.
Additionally, cleaning up unnecessary CPU processes also helps save energy for the device. Users can open the system's Task Manager by pressing Ctrl + Alt + Delete , go to Processes , and then check the Power usage column. Here, close applications that consume too much energy, especially the Google Chrome web browser if you have many tabs open.
Finally, if you're using an older laptop and notice that the battery isn't performing as efficiently, it's probably time to replace it. This is considered a simple but effective solution to help your laptop last for a few more years.
