Applications running on Android platform are one of the reasons for your Android device to be increasingly slow. Even these applications both consume memory, and also consume the battery very quickly. Therefore, to save battery, memory as well as your device to work faster, you should block these applications.
How to check which application is running background on Android
Menu Developer Options on Android provides access to many different useful features and detailed information about the function of your device. A remarkable option in this menu is Running Servicesproviding a list of applications operating in the background mode along with their corresponding RAM levels. Here's how to access it:
1. Open the application Settingsroll down and press About Phone.
2. Go to Software Information and click Build number 7 times to activate the Developer Options.

3. Enter the PIN (device password) and you will see the notice You're now a developer.
4. Back to the main Settings menu and press Developer options At the bottom.
5. Roll down and find Running Services. Click here to see the list of applications and services along with their memory use.

You can also navigate the battery use menu in Android to find out which applications consume the most battery. This information can help you make a wise decision about which application should stop to extend the battery life for your Android phone.
To check the application's battery level, open the menu Settings and go Battery. The most battery uses will appear at the top. Look at the list to find unnecessary applications, record them for the next steps.

How to prevent Android app running in the background
There are many ways to prevent applications from running on your Android, depending on whether you want to intervene immediately or adaptive and automatic solutions. We will consider some approaches.
1. Forced to stop the application
If you want a specific application to stop working in the background mode until you open it, you can force that application by the following steps:
- Open the menu Settings and go Apps.
- Roll on the list or use the search engine to find the application you want to stop and click on that application.
- Click on the option Force Stop.
- Press OK To confirm.

Note that this option is not perfect because some applications can start itself.
2. Limit the battery use for the application
On Android, you can limit the battery usage of specific applications, preventing them from running in the background unnecessarily. To limit the battery usage level for an application on your Android, follow these steps:
- Open application Settings and roll down to choose Apps.
- Locate and select the application you do not want to run hidden.
- Roll down and click on the option Battery in the part Usage.
- Select the option Restricted.

As noted in this menu, restricting applications can cause notice not displayed. Be careful using this option only for applications that do not send you sensitive information about time.
3. Activate the Adaptive Battery feature
The Adaptive Battery feature on Android uses Google Deepmind to understand your usage habits over time and limit the background operation for applications you do not often use. This option is ideal if you do not want to stop the application manually at all times or configure the battery usage for each individual application. To activate Adaptive Battery:
- Open application Settings and go Battery.
- Click Background Usage Limited.
- Click the three -dot menu in the upper right corner and select Adaptive Battery.
- Turn on the conversion button for Adaptive Battery.

If this utility is not enough to meet your needs, you can consider third -party applications like Greenify for hibernation applications and prevent them from running in the background. However, note that many of these applications are no longer positive development, so it is best to use Android built -in options.
I wish you success!
