# Overview of power management

> 
> 
> This guide helps you to develop energy-efficient products or
> applications that balance performance and power consumption.

Note

The guide uses the terms low-power state and sleep state interchangeably to indicate the power-saving mechanism.

It includes:

- Application processor subsystem (APSS) architecture
- CPU active power management through CPU frequency scaling mechanisms
and its tunables
- CPU idle power management through CPU sleep power states

The features and power states explained here are for reference only.

Note

See [Hardware SoCs](https://docs.qualcomm.com/bundle/publicresource/topics/80-70018-115/soc.html) that are supported on Qualcomm Linux.
