In one embodiment, a vehicle mirror includes an on-board diagnostics (OBD) transceiver and one or more processors. The processors access OBD data received by the OBD transceiver from an OBD port of a vehicle. The processors further monitor the OBD data to determine whether communications with the OBD port have been lost, determine an OBD speed of the vehicle, and determine an RPM of an engine of the vehicle. The processors further determine a GPS speed of the vehicle from a GPS transceiver. When communications with the OBD port are lost, the processors transition the vehicle mirror to a sleep power state. When communications with the OBD port have not been lost, the processors transition the vehicle mirror to the sleep power state when the OBD speed is determined to be zero for at least a first predetermined amount of time and the RPM of the engine is determined to be less than a threshold RPM amount.
