# Power states and features

The power saving states, or sleep states, enable you to review the power states before, during, and after running an application. The process ensures a comprehensive power sanity check of the device.

* [System-on-chip sleep states](https://docs.qualcomm.com/doc/80-80021-30/topic/qcs6490-soc-power-saving-state.html?product=895724676033554725\&facet=Power\&version=2.0-rc2)
  A system-on-chip (SoC) sleep state is a low power mode that the entire SoC enters when the device is idle or not actively running any use cases.
* [CPU power management](https://docs.qualcomm.com/doc/80-80021-30/topic/cpupowermanagement.html?product=895724676033554725\&facet=Power\&version=2.0-rc2)
  CPU power management techniques aim to reduce the power consumption of the CPU during both active and idle periods by using the resources efficiently.
