How Task Killers are Hurting Your Android Device

When an Android device comes out of the box for the first time, it´s fast and why wouldn´t it be, right? Unfortunately as time goes by you start to add more and more apps to your Android device and as a result, it´s not as fast as it once was. So, the word task killers start to cross your mind.

Since you want to improve your device´s performance you decide to add a Task Killer thinking it will kill what´s slowing down your device. You probably read somewhere that many Android users install them looking to improve the device´s performance and extend its battery life. But, is that true?

What is a Task Killer?

Task Killers kill apps that are running in the background erasing them from memory.  It´s an app that many users install on their Android devices to try and improve battery life and overall performance, but in reality, it only hurts the device by not letting it process certain things it needs to.

The Truth About Task Killers

Sorry to burst your bubble, but Task Killers don´t help your Android device.

You might see that your Android device’s RAM is full and believe that is the reason why your device is so sluggish but it´s the CPU that determines the speed of your device.

On an Android device, having an almost full RAM is a good thing, and when your device´s memory starts to fill, your Android begins to kill tasks you haven´t used in awhile. See? Android has its task killer installed and one that doesn´t hurt your device.

Task Killers Only Monitor Memory

Task Killers only monitor memory and not the CPU. For example, I downloaded a popular Task Killer from Google Play called Task Killer. As you can see in the image below, nowhere does the app indicate how much of the CPU the apps are using. It only monitors how much memory they are taking up. There is another way to get more storage on your Android device.

How Task Killers Hurt Your Device´s CPU

When you tell a Task Killer to kill certain apps, you´re using CPU cycles you wouldn´t be used. So, if you are constantly killing apps thinking you are going to help your device´s performance, what you are doing is draining the CPU since the apps will need to restart after being closed.

Task Killers can also cause apps to load more slowly since they are no longer on your device´s memory since and will have to load from storage. Since the app has to load from storage and not from your device´s memory, the process will drain more out of the battery.

Whether your device´s RAM is full or not, it is still going to use the same amount of RAM, so it´s better to leave the apps where they were in the first place.

How Task Killers Can Help

Task Killers aren´t 100% evil, they do have their good side, but it´s not very big. There are apps that misbehave and use more CPU than they should and using a task killer can be helpful since it kills this bad app. This is still not a good idea because it´s as if you tried to kill a fly with a shotgun. Sure, the fly is dead, but was it worth all the damage the process left behind? Not really.


The best thing you can do is to leave Task Killers out of your Android device.  Try to keep your Android device ¨healthy¨ by adding unnecessary apps and files that will only clutter it up. What do you think of Task Killers
