Internet keeps connecting when phone not in use

[Wolfhelm]

Hey all, did a bit of a search here and with google and cant find the reason for this.

My internet connection keeps connecting on my phone whenever I'm not using it. I've already disabled the weather auto-update so it isnt that. I've also made it so windows update is manual only.

I got a brief error yesterday about there not being a phone number argument for some url, but unfortunately I was laying in bed and didnt get it copied down.

Any way to prevent it from connecting to the net? Its killing my battery power when I'm not even using it.
