Example Concept: To optimize battery usage, utilize location services with the lowest acceptable accuracy and the longest feasible update interval. On Android, use the FusedLocationProviderClient to request location updates with balanced power accuracy. For iOS, configure CLLocationManager with desiredAccuracy set to kCLLocationAccuracyHundredMeters or kCLLocationAccuracyKilometer, and use significant-change location service when possible. Implement geofencing to reduce active tracking and rely on passive location updates when the app is not in active use.
