When I use Tasker, I have the GPS set to check my location every 5 minutes when the screen is on or off, but this kills my battery like no other. I'd prefer to be able to have it check my location with the tower triangulation (cell phone locations) every 3 minutes, and move the GPS check time to every 30-60 minutes. Anyone know of any way to do this? I haven't been able to figure it out yet. Thanks!
