Solution Approach 1:

The patent segments power usage monitoring into multiple dimensions: different components (CPU, GPU, display, etc.), different time periods, and different applications. By dividing the monitoring system into these segments, it achieves more precise measurement of power consumption patterns while maintaining comprehensive battery management capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces additional dimensions for power usage analysis beyond simple threshold monitoring. It adds temporal dimensions (time periods, duration), component dimensions (specific hardware components), and application dimensions (software applications) to create a multi-dimensional power usage profile that significantly improves measurement precision.

Inventive Principle:

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the complex monitoring task into manageable modules: an obtaining module for collecting parameters, a determination module for analyzing power usage, and a recording module for storing results. This modular segmentation reduces system complexity while maintaining comprehensive monitoring capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediary processing layers that aggregate and process raw component parameters before final analysis. These intermediaries (such as component weight coefficients and time period aggregations) simplify the relationship between numerous input parameters and the final power usage determination, reducing overall system complexity.

Inventive Principle:

AI summary

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