Why is my data usage so high?

[Windows Central Question]

data sense system usage

My data sense app shows more than 250 MB data used in just 6 days under "system". I cant figure out how my phone used this much data when my net usage is limited and I use WiFi mostly to download and browsing. What comes under the category "system" in data sense. Pls help..

Wow that's a lot, I have only 11 MB in system used in the past 8 days. Only thing I can think of is maybe a system update?

What is that system section for? What type of data is it downloading (aside from system updates)? These are things I wish Windows Phone indicated.

I think I may know what it is.... If you have any programmes allowed to be turned on in background then chances are its that doing the damage.
