I searched and found much of the information I was looking for, but I have a more specific question if somebody could help me.

I understand that geofencing is designed to be passive so as to not absolutely kill your phone's battery, but does it cause the phone to poll and check it's location more frequently if there are ANY fenced reminders?

For example, If I wanted to set a geofence reminder that is just for fun, meaning not pertinent to my day to day schedule, or even near me geographically (say, put a reminder to take a picture of the Golden Gate Bridge and fence it around San Francisco...although I don't live in California), does it noticeably drain battery power to the point where I shouldn't use it like that?

Thanks in advance

If I'm not mistaken the geofencing reminders use only cell tower triangulation. Data that your phone already has readily available at all times it has cell phone signal.

The battery impact of this feature is minimal as opposed to if it was GPS it'd be a large drain.

That what I'm curious about. If its using triangulation data that its accessing anyway, then great.
I was wary about the phone essentially saying "oo ok we have a geofence up, time to start doing a GPS loc check every x minutes"
