Abstract
A computer-based processing system (e.g., host server) is operable for receiving historical device operation information (power consumption data) collected during operation of the remote battery-operated device in accordance with a first set of operating parameters. The first set of operating parameters enable operation of the battery-operated device in a first operating mode. The processing system calculates an observed battery life for the device based on the received historical power consumption data and a power capacity value representing a power capacity of the battery resident in the device. This observed battery life may be output to a user and used to determine whether the device will meet a predetermined operational life. If not, parameters for the device can be modified and a new projected battery life calculated (simulation), with the new modified parameters controlling power consumption in the device.
