Source: [https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html](https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html)

Set up the software and hardware for power measurement as follows:

1. Flash the QCLI app image to the QCC730M EVK based on the power measurement use case.

    For detailed instructions about building and flashing an image, see [QCC730M Evaluation Kit User Guide – Zephyr (80-Y8730-252)](https://docs.qualcomm.com/bundle/resource/topics/80-Y8730-252).
2. Connect the board to the power analyzer as described in [Rework the EVK and connect the power analyzer](https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_tests.html#power_measurement_points).
3. Set up the console connection as described in [Set up console connection](https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_tests.html#console_connection).

See the following sections for how to perform the power measurement task for each use case.

## Soft-off mode

Source: [https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html](https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html)

To measure the power of soft-off mode, follow these steps:

1. Run the following command to enter the soft-off mode:

			

        > qpm softoff <sleep_time_ms>Copy to clipboard

			
    In this command, when `sleep_time_ms=0`, the device can only be awakened by an external wake-up pin.

			
    For details about how to use this command, see [QCC730.ZE.1.0 Programming Guide (80-Y8730-5)](https://docs.qualcomm.com/bundle/resource/topics/80-Y8730-5).
2. Observe the power analyzer and record the average power reading over a 30-second period.

## S2RAM mode

Source: [https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html](https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html)

To measure the power of S2RAM mode with Wi-Fi disconnected, follow these steps:

1. Run the following command to enter the S2RAM mode:

			

        > qpm s2ram <sleep_time_ms> 1Copy to clipboard

			
    In this command, when `sleep_time_ms=0`, the device can only be awakened by an external wake-up pin.

			
    For details about how to use this command, see [QCC730.ZE.1.0 Programming Guide (80-Y8730-5)](https://docs.qualcomm.com/bundle/resource/topics/80-Y8730-5).
2. Observe the power analyzer and record the average power reading over a 30-second period.

## IMPS mode

Source: [https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html](https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html)

IMPS is enabled by default. When Wi‑Fi is disconnected, the board enters IMPS based on the following conditions:

- If there are ongoing WMI-related operations (such as a Wi‑Fi scan), the board enters IMPS in 5 seconds.
- If there are no pending WMI-related operations, the board enters IMPS immediately.

## BMPS mode

Source: [https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html](https://docs.qualcomm.com/doc/80-Y8730-6/topic/power_measurement_use_cases.html)

To measure the power of BMPS mode, follow these steps:

1. Run the following command to establish a Wi-Fi connection:

			

        > wifi connect -s <SSID> -k <key-mgmt> -p <passphrase>Copy to clipboard

    - `<SSID>`: The Wi-Fi network name.
    - `<key-mgmt>`: The key management type (`0`: None, `1`: WPA2-PSK).
    - `<passphrase>`: The Wi-Fi password.
2. Run the following commands to enter the BMPS mode:

			

        > qbmps enable 1 120000Copy to clipboard

			
    After you run these commands, QCC730 enters BMPS mode for 120000 ms (120 seconds) and then exits the mode.
3. Observe the power analyzer and record the average power reading over a 30-second period.

## Wi-Fi TCP Rx mode

To measure the power of TCP Rx mode, follow these steps:

1. Connect a remote PC to the same AP.
2. Run the following commands on the QCC730M EVK and the remote PC to measure TCP Rx mode power.
