Abstract
Systems and methods are provided for optimizing battery life in an electronic device. The device is configured to make periodic assessments of battery capacity by measuring the DC resistance value of the battery cell. The temperature of the battery cell and/or other characteristics of the device are used to determine a threshold DC resistance level. If the measured DC resistance value reaches a determined threshold level, the device can initiate a power-saving mode in which an operating parameter of the device is adjusted to decrease power consumption.
