In some possible implementations of the embodiments of the present application, the first power supply current of the load module at any time in the time period from t0 to t1 can be obtained, and then the power supply current of the load module that changes with time in the time period from t0 to t1 can be obtained, and then the power consumption of the load module in the time period from t0 to t1 can be calculated by the above formula (1).

When the first switch module is turned on, the voltage across the first voltage divider module approaches 0, and at this time, the sampling control unit does not perform current sampling on the load module; when the first switch module is turned off, the sampling control unit performs current sampling on the load module.

In some possible implementations of the embodiments of the present application, the current detection method provided by the embodiments of the present application may further include: within a first time period, collecting a third voltage across the third voltage divider module through a sampling control unit, wherein the third voltage divider module is a voltage divider module arranged on a total power supply path of the power supply module; determining the current flowing through the third voltage divider module according to the third voltage and the resistance value of the third voltage divider module; when the current flowing through the third voltage divider module is greater than or equal to a current threshold, determining the current flowing through the third voltage divider module as the total current of the total power supply path; when the current flowing through the third voltage divider module is less than the current threshold, determining the sum of the first supply currents as the total current; and determining the total power consumption of the load module within the first time period according to the total current.

In an embodiment of the present application, when the current value calculated based on the third voltage and the resistance value of the third voltage divider module is less than the current threshold, it indicates that the accuracy of the current value sampled by the third voltage divider module is poor. At this time, by taking the sum of the power supply currents of each load module as the total current of the total power supply path, the accuracy of the total current of the total power supply path can be improved, thereby improving the accuracy of determining the total power consumption of the load modules.

In some possible implementations of the embodiments of the present application, the current detection method provided in the embodiments of the present application may also include: determining a first power consumption ratio of the load module within a first time period based on the first power consumption and the total power consumption; obtaining a second power consumption ratio of the load module in the second electronic device in the first time period; and determining an average power consumption ratio based on the first power consumption ratio and the second power consumption ratio, wherein the average power consumption ratio is used to measure the impact of the load module on the power consumption of the user using the electronic device.

It should be noted that the second electronic device is an electronic device of the same model and configuration as the first electronic device.

In some possible implementations of the embodiments of the present application, the power consumption ratio may be calculated according to the following formula (3):

kj＝Cj/C (3)

Wherein, in formula (3), kj is the power consumption ratio of load module j in the first time period, Cj is the power consumption of load module j, and C is the total power consumption.

After the power consumption ratio of the load module j of each electronic device in the first time period is obtained, the average power consumption ratio can be calculated according to the following formula (4):

Wherein, in formula (4), _AVGj is the average power consumption ratio, K0 _-j is the power consumption ratio of load module j of the first electronic device within the first time length, _Kij is the power consumption ratio of load module j of electronic device i within the first time length, i is a positive integer less than or equal to n, and the second electronic device includes electronic device 1 to electronic device n.

When the power consumption ratio of the load module j of the first electronic device within the first period is greater than the average power consumption ratio, it can be considered that the load module j has a greater impact on the power consumption of the user when using the first electronic device.

In the embodiment of the present application, the impact of the load module on the power consumption of the user's use of the electronic device can be measured.

It should be noted that the third electronic device is an electronic device of the same model and configuration as the first electronic device.

Exemplarily, assuming that the power consumption of load module j of 100 electronic devices in the first time period is obtained, among which the power consumption of load module j of the first electronic device in the first time period is greater than the power consumption of load module j of 87 electronic devices among the above 100 electronic devices in the first time period, a prompt message is displayed: "The power consumption of load module j exceeds 87% of the electronic devices, and the power consumption of load module j needs to be controlled."

Exemplarily, assuming that the power consumption of load module j of 100 electronic devices in the first time period is obtained, among which the power consumption of load module j of the first electronic device in the first time period is less than the power consumption of load module j of 87 electronic devices among the above 100 electronic devices in the first time period, a prompt message "The power consumption of load module j beats 87% of the electronic devices, please keep up" is displayed.

In an embodiment of the present application, heavy users and light users of the load module can be distinguished through the third power consumption of the load module in the first time period in other electronic devices, wherein a heavy user refers to a user whose load module consumes more power when using an electronic device, and a light user refers to a user whose load module consumes less power when using an electronic device.

In some possible implementations of the embodiments of the present application, after obtaining the third power consumption of the load modules in the third electronic device in the first time period, if the power consumption of most of these load modules is greater than the power consumption threshold, the next-generation electronic device can be optimized. For example, the power consumption of the display modules of the electronic device is mostly greater than the power consumption threshold. When producing the next-generation electronic device, the display modules of the next-generation electronic device can use screens with low power consumption or the next-generation electronic device can use large-capacity batteries.
