Abstract:
1. A method for determining power consumption and battery life in a battery-operated device having a battery for supplying power to the device, the method comprising: receiving historical power consumption data collected during operation of the battery-operated device in accordance with a first set of operating parameters, the first set of operating parameters enabling the battery-operated device to operate in a first operating mode; calculating, in a computer-based processing system, 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 within the device; outputting the observed battery life; obtaining the first set of operating parameters for use by the computer-based processing system; modifying one or more parameters within the first set of operating parameters to generate a second set of operating parameters that when loaded within memory of the battery-operated device will enable the battery-operated device to operate in accordance with a second operating mode; processing the second set of operating parameters and the power capacity value in the computer-based processing system and calculating a projected battery life for the battery when the device operates in accordance with the second operating mode; and outputting the projected battery life.
