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 Nperiod. 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 Nperiod. The electronic device records information of applications which run in the electronic device within the Nperiod when the power usage of the electronic device is abnormal.

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

An electronic device includes a screen, a processor coupled to the screen, and a non-transitory storage device coupled to the processor and configured to store one or more programs executed by the processor, the one or more programs causing the processor to acquire a cumulative time of each signal intensity of a wireless signal received or transmitted by the electronic device and/or a cumulative time of each mobile network service mode provided to the electronic device at a time interval, detect whether the electronic device, in a current mobile network service mode, is power-guzzling according to the cumulative time of each signal intensity and/or the cumulative time of each mobile network service mode, and generate a prompt message when the electronic device is power-guzzling.
