android os data usage

[Nafarmeskin]

Hi there

Im using the xz1 and now since three month when i check my mobile data usage the "android os" is using more than 10% of my data bundle while in other z1's its almost 2% only
But when i check the wifi data usage is almost 2% only (same period of time taken in consider in both wifi and Mobile data)

May i kbow the solution?
Ps: im not downloading or updating software through my data bundle, u tried both 4.2.2 and 4.3 softwares and its the same issue in both

Waiting for you valuable replies

that's odd, you can disable background data

I did that but then i couldn't receive the watssapp an blackberry messages until i open the apps

I meant to tap on the apps on that list and disable the background data to such apps

settings > data traffic > you should see a list > select one of the apps

now keeping whatsapp, bbm etc will use your data, that's normals, also 

open the playstore app > settings > uncheck auto update apps

The auto update is already disabled, and the now i went and disabled most of the app
Lets see tge usage for couple of days
Thanks
