Power settings are advanced configuration, most users should choose a role under [Device Config](/docs/configuration/radio/device) to manage power for their device and shouldn't ever need to adjust these settings.

The power config options are: Power Saving, Shutdown after losing power, ADC Multiplier Override, Wait Bluetooth Interval, Light Sleep Interval, Minimum Wake Interval, and Device Battery INA2xx Address. Power config uses an admin message sending a `Config.Power` protobuf.

4. If "Battery Charge Percent" (e.g., B 3.82V 60%) is not displayed on the screen, it means that the default value of "Operative Adc Multiplier" is too high. Lower the "Operative Adc Multiplier" to a smaller number (it is recommended to decrease by 0.1) until the screen displays "Battery Charge Percent". Enter the current "Operative Adc Multiplier" in use into the "Operative Adc Multiplier" field in the calculator. Also, input the "Battery Charge Percent" displayed on the screen into the calculator.

5. Click the "Calculate" button to compute the "Calculated New Operative Adc Multiplier", and set it as the new "Operative Adc Multiplier" for the device.
