Abstract:
A method of operating a control module of a mobile device that communicates with a cellular network and that is powered by an auxiliary power supply comprises generating an interrupt signal based on a tick of a system timer interrupt of the control module; incrementing a counter value based on the interrupt signal; and commanding the auxiliary power supply to cease powering the mobile device when the counter value is greater than or equal to a predetermined value.
