Abstract
A method includes measuring an operating parameter of a battery of a mobile device. The measured operating parameter is translated into an equivalent series resistance (ESR) value. The ESR value is adjusted by a correction factor to generate a corrected ESR value. The capacity of the battery is determined based on the corrected ESR value. The correction factor is automatically calibrated based on the measured operating parameter.
