How to find out which app is CPU hogging on your Android

How to find out which app is CPU hogging on your Android

Most of the applications you’ve already seen and decided to install on your Android device are there for a reason. Some are useful tools or clever games, others are Flappy Bird. And most of them have at least one problem. Today, most errors or defects are easy to detect. But when it comes to destroying the resources of a poorly optimised application, more work needs to be done.

You can easily detect vampires with RAM, memory or battery, but it’s a little more complicated when it comes to the processor. And the impact of some applications on your phone’s processor is too often ignored as insignificant due to the way Android works. The system monitors processor usage and stops some processes in the background for others that are currently active to consume more resources. All too often it is not enough that the device works as fast as it should.

For this purpose, we have drawn up an informative article that shows you how to find and complete the requests for cooperation with the subcontractor in just a few steps. If you are suspicious and want full control of the unit, be sure to read the following statement.

UPDATE:Google no longer allows access to third-party applications to hardware status for security reasons. It is therefore impossible to control the use of the exchange without routing the phone.

Use of integrated resources

They are limited, but should allow you to understand the basis of some requests. The measurements are mainly performed on batteries, but you can turn on the processor and act accordingly. But most of all, we have to make a difference. For example, if you are playing a game that contains many sources and images and your last registered CPU activity is high, this is normal. However, if an application running in the background causes CPU crashes, we assure you that this is not what you want.

If you don’t know how to turn on the processor on your Android device, follow these instructions

How to find out which app is CPU hogging on your Android

  1. Go to Settings.
  2. Open the About page and go to the construction number.
  3. Click the number 7 times to activate the developer options in the settings.
  4. Go back to the settings page and open new unlocked development options.
  5. Locate the control panel below and enable the Show CPU usage option.

You will now be informed about CPU activities in real time. This should allow you to find some background applications on your processor in an immeasurable way and separate them from the ignition.

If you are unsure how to force application shutdown, follow the instructions below:

  1. Open the settings.
  2. Click on the Developer option.
  3. Press Start Services or Processes.
  4. Stop making suspicious requests.

Remember, it’s only effective until the restart. If you start again, it is possible that the application procedure you interrupted resurfaces as a phoenix rising from its ashes. You should therefore consider removing a worrying application. If you are sure that your CPU usage is stable, you can also simply turn off on-screen CPU monitoring and continue working with the device as before.

Use of third party applications

Let’s move on to the real question. Most modern smartphones have integrated service tools. In most cases, however, they are not suitable for advanced reading, but for cleaning the cache. To do this, you need a third party tool that can be easily mixed and matched with the variety of tools available. Fortunately, we have made a list of free tools that are most suitable for this work, including their main functions.

Monitoring device for the Lite system


  • Excellent and simple, but colorful user interface.
  • Includes all major measurements, 6 to be exact. Including, of course, the operation of the processor.
  • Small size, but quite powerful tool.
  • Supports most commercially available devices.
  • Individual basic monitoring.


  • The fee-based option is much better in many ways, especially for advanced users.
  • Without widgets.
  • No processor temperature measurement.

You can download System Monitor Lite via this link.

SIDE EFFECT: System Monitor Lite has been removed from the Play Store.


Yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah:

  • Well thought out and small, as one would expect.
  • Rather, it is an integrated instrument, as it is integrated into the system and provides you with measurement values in real time.
  • The Public Order of Lawyers is well placed and informative.
  • Low load on the system.


  • As a System Monitor Lite, TinyCore is somewhat underestimated compared to the premium version, especially in terms of configuration.
  • There is no advanced reading in the free version.

You can download TinyCore via this link.


Yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah:

  • This is probably the best CPU monitoring application you can get for free.
  • Displays most of the functions available in the computer version of the application.
  • Supports most available phones.


  • It is not as visually appealing as some other applications.
  • There’s too much publicity. Includes video advertising with pop-up windows and all that jazz that can drive you crazy and reduce your overall experience.

You can download CPU-Z by clicking on this link.

Please note that these instruments exist only for control purposes. It’s just a first step. As soon as you know the reason for the CPU jumps, you need to terminate the applications manually to load the CPU.

This is the end of our list and instructions. We hope you find them useful. Also don’t forget to include your opinions, questions or suggestions in the comment section below.
