Look through your phone's pages until you see a bar displaying Wi-Fi, Data, Brightness, etc. If you see the Data icon lit up, click on that and it will shut off Data connections. You will still be able to use your Wi-Fi connections if it is lit up.

Slide down from the top and tap 'mobile data.' Battery drain is likely not caused from having mobile data enabled. More than likely it is from an app that is left open, wifi, bluetooth, etc.
