System is consuming data of internet as per Data sense. How to stop?

[Windows Central Question]

I have Nokia Lumia 525. As soon as I get connected to net, Data sense shows that System data consumption automatically starts. I have put off all apps from running in background.
Data usage by all apps is 15MB but actual data consumption is 120 MB. Can not find what exactly is consuming data and how to stop
