# 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/80-80022-30/topic/qcs6490-soc-power-saving-state.html)
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/80-80022-30/topic/cpupowermanagement.html)
CPU power management techniques aim to reduce the power consumption of
the CPU during both active and idle periods by using the resources
efficiently.
