# 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/80-70020-30/topic/qcs6490-soc-power-saving-state.html)
The System-on-chip (SoC) supports several sleep states based on the requirement of
resources, such as, double data rate (DDR), crystal oscillator (XO)
clock, digital power supply `(Chip_CX)`, and memory domains power
supply `(Chip_MX)`.
- [CPU power management](https://docs.qualcomm.com/doc/80-70020-30/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.
