Why my mobile eats hell lot of wifi data I have a Micromax Canvas a200 turbo mini. I have started using WiFi since last month. In one month "Android OS" and Google Chrome have used 63 GB of WiFi data. I have tried using third party apps, but they are only useful when you are using cellular data. I have tried reset factory as well.

What would cause this high data usage?

You can try opera max. It is VPN service that having app management features. There you can manage which app to allow network connections. And then only allowed apps would be able to access network bandwidth.
