Abstract
Embodiments of a system, method and apparatus are described for estimating the elapsed power consumption of an electronic device. A plurality of power consumption rates is associated with a plurality of operating states, respectively, of one or more electronic components of an electronic device. As the electronic device operates over the plurality of operating states, a partial battery consumption estimate is calculated for the time spent in each state, multiplied by a respective power consumption rate in each particular operating state. A summation of the partial battery consumption estimates is summed to produce an elapsed power consumption by the electronic device.
Claims20
An electronic device, comprising:
- a battery;
- an active electronic component powered by the battery, operating in a plurality of operating states over time;
- and
- power consumption measurement circuitry, configured to determine an elapsed power consumption of the electronic device, the elapsed power consumption of the electronic device comprising a summation of a plurality of partial power consumption estimates associated with at least the active electronic component, each partial power consumption estimate comprising a power consumption rate associated with each of the plurality of operating states multiplied by an elapsed time spent in each of the plurality of operating states, respectively.
A method for determining an elapsed power consumption of an electronic device, comprising:
- determining a plurality of partial power consumption estimates associated with a first active component of the electronic device, each partial power consumption estimate comprising a power consumption rate associated with the first active component in each of a plurality of operating states multiplied by an elapsed time spent in each of the plurality of operating states, respectively;
- and
- summing the plurality of partial power consumption estimates to produce the elapsed power consumption.
