Note: The settings name can vary on different Android smartphones and these steps are performed on a ‘OnePlus’ device.

• On your Android phone, go to “Settings.”
• Now tap on the “Wi-Fi & Network” (known as wireless connections or ‘Wi-Fi and internet’ on some phones)
• Click on “Data Usage” (otherwise termed ‘use of data or ‘data usage control’)
• Now tap on “Cellular Data Usage”, and you will have a list of the available apps.
• Select the app and toggle off “Background Data.”

Another way is to manage the data usage in apps individually. For that, 

• Go to “Settings.”
• Click on the “Apps & Notifications” section
• Locate the individual app and tap on it
• Now Click on “Mobile Data & Wi-Fi.”
• Then, toggle off “Background Data.”

Using the NetGuard app

NetGuard is a 3rd-party app that blocks internet access to Android apps without any root permission, ads, or privacy concerns. It supports all system apps. The walkthrough of using it is as follows.

1. The app needs to be turned on initially, just like a VPN. 
2. A list of the system’s apps is visible. There will be symbols for ‘Wi-Fi’ (on the left) and ‘Data’ (on the right) next to the apps. 
3. The Wi-Fi and data symbols will also have a ‘green’ or ‘red’ representation. Green indicates on, and red indicates off. From there, you can easily “Turn Off” internet usage.

Minimize the Internet Usage

In Android 7.0 or higher, there is a data saver feature to reduce consumption. 

1. Go to “Settings.”
2. Click on “Wi-Fi & Network.”
3. Tap on the “Sim & Network.”
4. Click on “Data Saver” and enable it.
5. You will have a list of apps from which you can save data and stop the downloads, auto-play, unnecessary images, etc.
