Many people have concerns about why Android devices slow down with time. There could be various reasons behind it, like junk files, faulty hardware, bugs, etc.

In most cases, the apps running in the background slow up the devices. On a Windows computer, killing processes and apps is easy due to the task manager’s availability. However, on Android, there’s no such option to kill apps. Users can kill apps by going through the Apps settings, which requires lots of time and can be tedious.

If you are wondering how to improve your device performance and battery life, you must use the Android task manager apps. These Android task manager apps or app killers can find and kill apps running in the background.
