Determining whether a change in power usage is abnormal when power usage exceeds a threshold based on additional metrics of components in an electronic device

摘要

In a method for detecting power usages of an electronic device, parameters of components of the electronic device and a power usage of the electronic device are obtained within a predetermined N^th period. The electronic device determines if the power usage of the electronic device is normal according to the parameters of components of the electronic device within the N^th period. The electronic device records information of applications which run in the electronic device within the N^th period when the power usage of the electronic device is abnormal.
