Dynamic Switching Power Limit and Core Configuration
2023-2024
Context
Extending battery life in devices with CPUs featuring hybrid architectures is essential for enhancing user experience and device efficiency. Power consumption optimization can be achieved by dynamically adjusting CPU core configurations based on usage scenarios. This project focuses on reducing power consumption by modifying core settings during specific operational modes, particularly when using discrete graphics in battery mode. By implementing dynamic core adjustments, we aim to improve battery performance without compromising device functionality.

We conducted an experiment to validate a dynamic power management strategy for extended battery life. The methodology involves:
Objective: Optimize battery life by reducing power consumption through dynamic CPU core adjustments.
Methodology:
- Core Configuration Adjustment: Modify the CPU core settings to deactivate certain cores during specific modes.
- Power Limits Adjustment: Define and implement CPU power limits appropriate for the new core configuration.
- System Settings: Update system firmware and software configurations to support dynamic switching.
- Validation: Perform tests to ensure power settings are correctly applied and verify compatibility with existing operational modes.
This approach confirms the effectiveness of adjusting CPU cores and power settings to minimize power consumption during specific scenarios.
Conclusion
The experiment successfully demonstrates that dynamic adjustment of CPU core configurations can significantly extend battery life in devices with hybrid architectures. By reducing the number of active cores and optimizing power limits during certain modes, we achieve lower power consumption while maintaining necessary performance levels. This strategy provides an effective solution for enhancing battery performance in devices operating under discrete graphics modes, contributing to overall energy efficiency and user satisfaction.
