Location tracking.

  • Continuously track your location while on the move to improve notification accuracy.
  • Tracking requires resident multitasking.
  • While designed to conserve battery power, long distance travel may increase battery consumption. (Reference: Traveling about 30 kilometers with iPhone 6 consumes about 4% of the battery)
  • It is also possible to reduce the battery consumption of the entire iPhone if you are not using life recording apps, etc.
