Network Disconnection Mechanism for Mobile Device Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices experience increased power consumption due to applications waking the system up frequently, especially as the number of installed applications grows, leading to reduced battery life and standby time.
Innovation Solution
A control method and mobile device implementation that sets a network restriction list excluding background applications, determines a trigger condition of the screen being off for a preset time without external power, and initiates a network disconnection mechanism to restrict unnecessary connections, thereby conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If applications are allowed to run in the background and maintain network connections, then application functionality and responsiveness are improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts network connection states based on screen status and power supply conditions. When the screen is off and no external power is supplied, the network disconnection mechanism is triggered to restrict network connections. When the screen is on or external power is available, network connections are maintained, allowing applications to function normally while consuming power only when necessary.
Solution Approach 2:
The system changes the network connection parameter (connected/disconnected) based on system state parameters (screen status, power supply status). By monitoring these parameters and adjusting the network connection state accordingly, the system achieves dynamic power management that reduces energy consumption during low-activity states while maintaining functionality when needed.
2Use of energy by moving object
If network connections are restricted for background applications, then power consumption is reduced, but application responsiveness deteriorates
Solution Approach 1:
The restriction is not static but dynamic, activated only when the screen is off and no external power is supplied. This dynamic approach ensures that applications remain responsive when the user is actively using the device (screen on) or when power is abundant (external charging), while only restricting connections during low-activity, low-power states.
Solution Approach 2:
The system preemptively disconnects network connections before power consumption becomes a critical issue by detecting the combination of screen-off state and lack of external power supply. This preliminary action prevents unnecessary power drainage while maintaining the ability to restore connections quickly when conditions change.
3Use of energy by moving object
If the network disconnection mechanism is activated frequently, then power consumption is controlled, but system stability deteriorates
Solution Approach 1:
The system performs preliminary checks of multiple conditions (screen status, power supply status, trigger condition) before activating the network disconnection mechanism. This preliminary action ensures that disconnection only occurs when all necessary conditions are met, preventing premature or unnecessary disconnections that could cause system instability.
Solution Approach 2:
The system continuously monitors system status parameters and provides feedback to the network disconnection mechanism. Based on this feedback, the system decides whether to activate or deactivate network restrictions, creating a closed-loop control system that maintains stability by responding appropriately to changing conditions rather than operating on fixed timing.

AI summary
The disclosure provides a control method for network disconnection during screen off and a mobile device. The control method is applicable to a mobile device, and includes: setting a network restriction list based on a plurality of applications of the mobile device, where an application run in a background in the applications is excluded from the network restriction list; determining, based on a system status of the mobile device, whether the system status meets a trigger condition, where the trigger condition is that a screen of the mobile device is off for more than a preset time, and there is no external power supply; and starting a network disconnection mechanism when the trigger condition is met, to restrict network connections of the applications in the network restriction list, and maintaining the network connections when the trigger condition is not met.
