Mobile Terminal Sleep Method Reducing Standby Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminal devices in standby mode continue to consume significant energy, leading to inefficient battery life and prolonged startup times when transitioning from sleep to active mode, negatively impacting user experience.
Innovation Solution
Implement a sleep method that records service state information related to data connections, turns off unnecessary services, and controls the processor to enter a sleep mode, and a wake method that quickly restores these services when needed, allowing for efficient power management and rapid system entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the mobile terminal device is turned off through temporary power-off manner to save energy, then power consumption is reduced, but startup time becomes very long due to full system initialization
Solution Approach 1:
The patent applies local quality by differentiating between different components of the system. While the processor enters a deep sleep mode, specific services (GPS, WIFI, Bluetooth) are selectively maintained in a turned-off state rather than completely shutting down all system functions. This selective approach allows the device to save power while maintaining the capability for rapid service restoration, thus reducing both power consumption and startup time simultaneously.
2Use of energy by moving object
If the mobile terminal device remains in working state with touch screen off to save energy, then some power is saved compared to full operation, but energy consumption remains very large
Solution Approach 1:
The patent implements dynamics by introducing a sleep mode that dynamically adjusts the operational state of the processor and services based on usage needs. The system can transition between working state and sleep mode, with the processor entering sleep mode to significantly reduce power consumption while maintaining the ability to quickly wake up and restore services, thus achieving both power savings and good user experience.
3Use of energy by moving object
If all services are turned off to achieve maximum power saving, then energy consumption is minimized, but service restoration time increases
Solution Approach 1:
The patent applies preliminary action by pre-recording the state information of services before they are turned off. When the processor wakes from sleep mode, the system can quickly restore services by referencing the pre-recorded state information, significantly reducing service restoration time while maintaining maximum power saving benefits during sleep mode.
Data Source
AI summary
The present invention discloses a sleep method, including: when determining select a sleep mode of a mobile terminal device, recording, by the mobile terminal device, service state information related to data connection; according to the recorded service state information related to the data connection, turning off a service that is related to the data connection and is in a turn-on state; and controlling a processor to enter a sleep mode, thereby saving the power consumption of the mobile terminal device more than that in the prior art.
