Task Killer is one of the most popular utilities in the Google Play Store store, but they are completely worthless. In fact, it can make your phone slower.
Task Killer closes the background app to free up RAM. It works with the idea that freeing RAM can improve performance but this is not true. Android is designed to keep the app on RAM so it can store them faster, it will close the app whenever it needs to release more resources. More importantly, certain app processes will restart as soon as they are 'killed' because they need to run in the background.
Similarly, you don't need to worry about manually closing apps. Android manages this automatically. If Android needs to release the resource, it will close the app you didn't use for a while.
If not, leave them alone, leaving them in memory will have little or no effect on performance and battery life. It helps apps load faster when using them later.
You should avoid using apps that promise to improve phone performance, including speeding up RAM, speeding up SD cards, etc. These apps rarely work effectively, they often come with ads and Can really slow down your phone.
Also, you should not use defragmentation apps for Android. Your phone does not need defragmentation, it uses flash memory and is not affected by fragmentation. All phone defragmenting apps on Google Play will not make your phone run faster.

To use ART, users need to switch from Dalvik to ART on KitKat machines by Settings> Developer Options> Select Runtime .
These are some of the methods to help users improve the speed and performance of Android devices. During use, you should control the apps installed on the device, as well as delete the junk files that are harmful to the device, slowing down the processing of the device.
