Power Management Mode Switching Based on Usage Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management solutions for electronic devices do not automatically adjust power consumption based on usage patterns and time segments, leading to inefficient battery usage and the need for manual user intervention to save power.
Innovation Solution
A method for power management that determines a predefined time segment, monitors current power consumption rate, device state, and usage pattern, selects a power saving mode, and performs operations such as adjusting screen brightness, terminating background applications, and controlling network access to optimize power usage.

Engineering Contradiction Analysis
1Duration of action of moving object
If power saving mode is activated to reduce power consumption, then battery life is extended, but device functionality and performance are reduced
Solution Approach 1:
The system dynamically adjusts power saving modes based on monitored usage patterns and time segments. Instead of a static power saving mode, the system transitions between different power saving levels (first, second, and third modes) according to actual device usage, thereby optimizing the balance between battery life extension and device functionality maintenance.
Solution Approach 2:
The system changes operational parameters by monitoring power consumption rates and adjusting power saving mode thresholds. When power consumption exceeds predetermined thresholds during specific time segments, the system modifies its behavior by switching to appropriate power saving modes, thus adapting device performance parameters to match battery conservation needs.
2Ease of operation
If manual user intervention is required to manage power consumption, then user control over device behavior is maintained, but user convenience and time efficiency are reduced
Solution Approach 1:
The system performs self-service by automatically monitoring its own power consumption patterns, determining usage segments, and switching between power saving modes without requiring manual user intervention. The device autonomously manages its power state based on predefined thresholds and monitored usage, freeing the user from manual power management tasks while maintaining optimal battery life extension.
3Measurement precision
If power consumption is monitored continuously to optimize battery usage, then power management precision is improved, but additional power is consumed by the monitoring process
Solution Approach 1:
The system applies partial monitoring action by monitoring power consumption parameters selectively rather than continuously at maximum precision. It monitors key parameters (power consumption rate, usage patterns, time segments) at sufficient levels to trigger mode transitions, avoiding the excessive energy cost of continuous high-precision monitoring while maintaining adequate measurement precision for effective power management.

AI summary
The present disclosure relates to a method for power management of an electronic device, the method comprising determining an onset of a predefined time segment corresponding to a time period; obtaining power consumption data by monitoring at least one of a current power consumption rate, a current device state, and a current device usage pattern of the device during the predefined time segment; selecting a power consumption category for the predefined time segment based on the power consumption data; switching from a first power saving mode active on the device to a second power saving mode based on the selected power consumption category; and performing one or more operations on the device based on the second power saving mode.
