OK! Doing some research.
Clicking on Google location services brings up this message
"Allow Google's location service to collect anonymous location data. Collection will occur even when no applications are running."
Standalone GPS
"By selecting "standalone GPS Services", you are enabling access to all location information by any third party through web access or any software or peripheral components you chose to install, download, add or attach to the device or any other means. Enabling this functionality could pose certain risks to users of this device".
I think we all knew that.
VZW location services
"By selecting VZW location services, you are enabling Verizon Wireless and third party authenticated and validated location services to access certain location information available through this device and/or the network."
So all these are about collecting data. This menu is different from what I am used to on the X.
This is how I remember the menu, but I could be wrong. I'm old and it was a week ago that I had the phone. You can't expect me to remember that far back.
Tutorial
In that tutorial video it seems pretty clear that you are using verizon towers to locate where you are, not for collecting data.
So is the "VZW location Services" the same thing on this phone or is it different?
For myself I have to be able to let the phone ID where I am through the towers because I am on airplanes so much. When I am on the airplane (not flying, just on the ground), you can't pick up GPS so it will never know where you are. Im traveling through time zones so often that I rely on my phone to be accurate.
Getting a little off track, still trying to figure out what causes the drain.
