https://devzone.nordicsemi.com/f/nordic-q-a/36598/high-power-consumption-when-softdevice-enabled-without-advertisingHello! I am developing a bracelet product base on nrf52832. I have a problem with softdevice&#39;s power consumption , when softdevice enabled,the power comsuption will rise about 500uA more than softdevice is not enabled.

Some peripheral or driver, might e.g. have turned it on and forgotten to turn it off again after use.&nbsp;</p> <ol> <li>Are you using custom code or an example? Can you share the rest of it?</li> <li>Are you developing on a development kit or a custom PCB?</li> <li>Will I be able to run your code on a nRF52 DK kit and measure myself?</li> <li>What low frequency clock source do you use?</li> <li>Are you using the Logger library? It might help if you turn it off.&nbsp;</li> </ol> <p>&nbsp;</p><div style="clear:both;"></div>
