Source: [https://docs.qualcomm.com/doc/80-70014-30/topic/suspendpowermanagement_0.html](https://docs.qualcomm.com/doc/80-70014-30/topic/suspendpowermanagement_0.html)

The Suspend state is the deepest sleep state in the APSS with all user space
        processes frozen, and drivers releasing their resources. During Suspend state, all cores
        enter C4 state followed by AOSD Sleep state.

A user space module can configure the Suspend state using the following command:

echo mem > /sys/power/autosleepCopy to clipboard

## Check suspend statistics

To display suspend statistics run the following commands:

cd /sys/power/suspend_stats
    cat success
    cat failCopy to clipboard

The success count indicates the number of times the APSS successfully entered the
                Suspend state.

The fail count indicates the number of times the APSS fails to enter the  Suspend
                state.
