System using too much mobile data itself

Please see attached screen. Sony are you kidding me??? 

 1,22GB taken by the system itself. 

This is called optimization...

1,22GB of data taken in the background:

 Good job, keep it up.

it's some kind of a glitch in displaying cellular data usage. if you add the amount of data used by all apps WITHOUT Android OS, it will equal the sum displayed on the top. try it out yourself.

It doesn't work as you said. It shows Cbrome itself used 0,99GB and rest of the apps combined with Chrome much much more than 1,22GB. Hence system used so much.

for me it's as follows:

total usage - 1.35 GB

Android OS - 748 MB
Play Store - 330 MB
Snapchat - 190 MB
Instagram - 147 MB

at this point it's already 1.35 GB but the list goes on:

removed apps - 108 MB
Brave Browser - 101 MB
Slide for Reddit - 75.46 MB
Firefox Focus - 70.39 MB

the list goes on and on. if I add the whole list together, it sums up to around 2 GB, i.e. 700 MB more than shown sum of 1.35 GB. the difference is coincidentally the amount of data supposedly used by Android OS.
