I am using a DROID2. I turn on WIFI and connect to my home router when I am at home. I was under the impression that the phone would not be using any data when connected to WIFI. When I just checked out usage, it is showing usage every 30 minutes all day & night (even when connected to the WIFI). Any suggestions
Also you should check the WiFi sleep policy. Settings > wireless & networks > wireless settings > menu > advanced > sleep policy.
