摘要： A method for reducing battery consumption while automatically tracking mileage may include detecting a trip initiation event at a location of a mobile device, initiating, by activating a geolocation sensor, tracking of global positions, and obtaining a global position of the mobile device corresponding to the location. The method may further include adding the global position to a global position sequence, and detecting, using trip updating parameters, a sequence of trip updating events. The trip updating parameters may include an update distance, an update period, and a reduced update velocity. The method may further include obtaining a sequence of updated global positions corresponding to the sequence of trip updating events. The method may further include adding each updated global position to the global position sequence, detecting a trip termination event, and stopping, in response to detecting the trip termination event, the tracking of global positions by deactivating the geolocation sensor.
