Abstract: An apparatus used with a processor to perform fuel gauge operation for a battery of a portable device includes a voltage measuring circuit and a control circuit. The voltage measuring circuit periodically measures and records a battery pack voltage for the battery according to time information received from the processor after the processor enters a sleep mode. The control circuit generates an accumulation result by calculating and accumulating at least one value of battery characteristics according to the battery pack voltage, and compares the accumulation result with a reference threshold of battery characteristics to determine whether to trigger an interrupt to wake up the processor, so as to cause the processor to update a battery cell voltage and an internal battery resistance of the battery for performing fuel gauge operation.

Abstract: A method for performing power consumption control is provided, where the method is applied to an electronic device. The method includes: sensing a current on a current path between a battery and at least one portion of the electronic device by performing sampling operations to generate a plurality of samples; performing calculation on the samples to monitor the current; and based upon the calculation, when it is detected that the current reaches a predetermined threshold, triggering the battery into a second mode from a first mode. In particular, performing the sampling operations to generate the plurality of samples further includes: utilizing an analog-to-digital converter (ADC) to perform the sampling operations on a voltage difference corresponding to the current to generate the plurality of samples. For example, the voltage difference can be obtained by probing two terminals of a resistor or a Hall component. An associated apparatus is also provided.
