Multi-OS Power Saving Mode Control Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart terminals with multiple operating systems face a significant decrease in standby capability, as existing power saving modes are not suitable for multiple operating systems, leading to reduced user experience and increased power consumption.
Innovation Solution
A power saving mode control method and device that sets multiple levels of power saving modes for each operating system, allowing users to select and trigger the appropriate mode for each system, including hardware and software settings, standby modes, and shutdown options, to optimize power consumption and extend standby time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If power saving mode is implemented for single operating system, then power consumption is reduced, but it becomes unsuitable for terminals with multiple operating systems
Solution Approach 1:
The patent divides the power management system into separate modules for each operating system. Each operating system has its own power saving mode configuration and control mechanism, allowing independent power management. This segmentation enables the system to apply appropriate power saving strategies to each OS without interference, resolving the contradiction between energy efficiency and multi-OS adaptability.
Solution Approach 2:
The patent creates a universal power management framework that can handle multiple operating systems through a common interface and control structure. The power management module is designed to be OS-agnostic, supporting different OS types (Android, iOS, Windows, etc.) through standardized power mode definitions and transition mechanisms, thus achieving both energy savings and broad applicability.
2Adaptability or versatility
If multiple operating systems are added to enhance functionality, then system capability is improved, but standby capability decreases
Solution Approach 1:
The patent implements dynamic power management that adjusts system state based on real-time conditions. The power management module continuously monitors OS activity, resource usage, and power consumption patterns, dynamically transitioning between different power modes (active, standby, sleep) for each operating system. This dynamic approach allows the system to maintain multiple OS capabilities while optimizing standby time by putting inactive OS components into low-power states.
Solution Approach 2:
The patent employs a strategy of temporarily suspending or discarding non-critical OS functions during standby periods, with the ability to recover and resume them when needed. Less frequently used operating systems or their components can be placed in a suspended state with minimal resource allocation, extending standby time while maintaining the capability to quickly reactivate them when required.

AI summary
A power saving mode control method and device for multiple operating systems include: setting corresponding power saving modes for each of the multiple operating systems in advance; and determining an operating system of which a power saving mode is triggered, and causing the operating system of which the power saving mode is triggered to enter the corresponding power saving mode.
