If you use a location context but GPS is not on, it uses your network location to determine location. That's why they recommend using a large radius unless you explicitly turn on GPS. All of the scan frequencies are defined in the Tasker settings if you are worried about battery life.Okay, maybe I am missing something, but how does the phone know your within 3km of work? Does your GPS run 24/7? Mine is on, but only "activates" when I open up Foursquare or Google Maps, then goes off when app is closed?
This is one of the reasons I do not use location based apps that know your close to target to pick up toilet paper.
Maybe I am missing something, but would love to not have GPS on 24/7 draining my battery and start using Location Base Service apps.
Can anyone enlighten me?
