Continuous GPS tracking kills battery. A typical 1 Hz GPS session (one fix per second) burns through 10–15% of battery per hour. For an 8-hour delivery shift or a full-day hike, that's a dead phone before the day is over. Most location plugins give you one knob to tune: the distance filter — the minimum distance in meters between location updates.
