ABSTRACT:
A system according to various aspects of the present invention predicts remaining battery capacity for a battery used by a device. The system includes a memory that stores indicia of remaining battery capacity and a plurality of predefined increments of battery capacity consumption. The system further includes a circuit that determines a duration of operating corresponding to one or more of the increments and stores in the memory a predicted remaining battery capacity, adjusted in accordance with the duration and the one or more increments. Other systems, according to various aspects of the present invention, further include a display indicating remaining battery capacity, for example, as a percentage of initial battery capacity, and/or temperature compensation.
