Powersave
Powersave refers to techniques and configurations aimed at reducing the power consumption of electronic devices and computer systems, typically to extend battery life or reduce energy costs. It encompasses both hardware capabilities and software policies and is common in mobile devices, laptops, embedded systems, and data centers.
Common methods include entering low-power states during inactivity (sleep, standby, or hibernate); turning off or disabling
Power management policies are implemented at firmware, hardware, or operating system levels. In Linux, for example,
Hardware design also contributes to powersave, with energy-efficient components, advanced sleep states, and support for standards
Measuring powersave effectiveness involves power profiling and energy accounting using sensors and tools, with metrics like
