    this will kill the battery? so if siri is on...location is always on?

    sooo if you have a location based reminder...the gps stays on until this reminder is up....ouch

    Not necessarily. You can tell if the GPS is actively on by an icon in the top toolbar, it's the little triangle/arrow next to the Bluetooth icon in this picture:

    Did you set up a reminder with Siri?

    When you set a location-based reminder it seems to activate location service and have it stay on. This has to be battery-killing, no?

    Supposedly it only turns on a passive watch for cell id (and perhaps WiFi hotspot) changes, something that has to occur anyway in normal operation.

    Thus the battery impact should be negligible.

    Actually, yes I did. You asked "if siri is on...location is always on?"

    I interpreted that question to be, "If Siri is on, is my GPS on" - e.g. draining the battery faster.

    My answer was "Not necessarily" - and I gave you an easy way to tell if the GPS receiver is on.
