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.
