Abstract

A technique for estimating current consumption of an electronic device such that current consumed during reception of bursts is utilized in calculating the remaining battery power. By determining the time duration of each reception burst and the charge consumed during each burst, the total charge consumed by the reception bursts is calculated. The total charge calculated is used to determine the remaining battery power.
