Adaptive power estimation system

Last updated:

Abstract:

Systems, devices, media, and methods are presented for adaptively estimating power. The systems and methods measure an electrical potential of a power source coupled to a wearable computing device and determine a current power consumption on the power source. The systems and methods identify a current slope value mapping the electrical potential to an estimated capacity percentage based on the measured electrical potential. The systems and methods determine a correction value based on the current power consumption and the current slope value and generate a current capacity value from the electrical potential and the correction value. The systems and methods cause presentation of a representation of the current capacity value within a power indicator and control one or more processes operating within the wearable computing device based on the current capacity value.
