1. A method for preserving battery power in a tracking device configured to operate in a lost device mode and comprising a first transceiver and a second transceiver, comprising:
when the tracking device is configured to operate in a lost device mode:
providing, by the first transceiver, a location of the tracking device to a central tracking system; and
in response to receiving a confirmation that the location of the tracking device was received, configuring the tracking device to operate in a power preservation mode by disabling the first transceiver such that the tracking device periodically transmits beacon signals for receipt by a device within a communicative range of the tracking device via the second transceiver, the device configured to provide location information representative of the tracking device to the tracking server.
