5+ Best App Killers For Android To Improve Battery Life & Phone Performance

Has your Android device become slow and started to drain a lot of battery power lately? But you don’t really


Has your Android device become slow and started to drain a lot of battery power lately? But you don’t really know what to do? We have a possible solution for you…

What actually happens is that in case you install a poorly developed app on your device and run it, the app will start to consume a huge chunk of RAM and resources, and continues to run in the background. This negatively affects your device’s performance.

In order to help you find and stop any of the resource hungry apps, we have listed the best app killers for Android.

But before we move onto our list of six best app killer for Android, we would first like to provide you some quick facts about how Android OS handles memory and why it could be a bad idea to frequently use an app killer to stop/kill essential apps on Android.

How Android OS Handles Memory/RAM?

For the beginners or for those who are unaware about the working of the Android OS, it is important to understand that Android handles the RAM in a completely different way as compared to the Windows OS (we compared it with Windows because that is what most of the users have used).

If you know how to see a list of currently running apps on Android then you must have noticed that there are several apps running all the time, even though you are not using them, right?

That is how the Android is designed to handle apps. And that is exactly what allows the Android device to let you quickly open the apps as well as switch between multiple apps without waiting for them to load. Because those apps are already loaded in the RAM.

And in those cases when you are running an app that requires a lot of RAM, for example, a gaming app, the Android OS will automatically kill the least necessary apps to free up memory and allocates it to the game.

And once you close that game, Android will automatically reopen any essential app that was killed/stopped during the process.

Even though the Android OS is smart enough to automatically kill and restart the background apps depending on your usage, but at times, some apps are poorly developed and have some flaws/memory leaks that use all of your device’s resources, ultimately making your device slow or unresponsive.

That is exactly when a need to use an app killer arises, which is designed to kill any buggy app or unresponsive task and will help you to easily stop that app from eating up the resources hence making your phone responsive again.

How To Make The Most Out Of App Killer On Android

We have seen in most of the cases that app killers and task manager apps do more harm to your Android device than doing much good because the app killer itself would be continuously running in the background to help you monitor and stop an unresponsive app.

Or in worst cases, using the app killer to kill essential apps will have a direct impact on your device’s performance that would ultimately drain the battery a lot faster.

You must be wondering that how killing an app is going to have any impact on the battery. Right?

What actually happens is, whenever you try to kill an app that is necessary and should not be stopped, Android will automatically restart it.

Moreover, this whole stopping and the restarting process of apps will unnecessarily consume your device’s resources, slows it down, and will negatively affect the battery.

With that being said, app killers and task managers are specifically designed to help you kill and stop the badly written app that continues to run in the background all the time without any reason.

Now, as you have learned about how to make the most out of the app killer, so without any further ado here are the six best app killer for Android:

The Android stock app killer is not only limited to that, it even allows you to force stop/kill those apps that are conflicting with your device or are resource hungry.
