# Power states and features

The power saving states, also referred to as 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.

The SoC supports multiple 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/80-70015-30/topic/cpupowermanagement.html)**  

CPU power management techniques aim to reduce the power consumption of the CPU during         both active and idle periods by using resources efficiently.
