https://devzone.nordicsemi.com/f/nordic-q-a/114460/nrf5340-power-measurement-regHi, In our new project, we are using the nRF5340 WLCSP package and configuring the system ON - low-power mode in our application code. We measured the current consumption of the controller in an idle state of the system ON - low-power mode by controllingen-USTelligent Community 13Thu, 05 Sep 2024 11:00:03 GMThttps://devzone.nordicsemi.com/thread/501331?ContentTypeID=1Thu, 05 Sep 2024 11:00:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c21a2358-9fd8-4e28-a5a0-22f2f036604aPriyanka<p>Hi,</p> <p>Please make sure that all your GPIOs are in a known state, i.e. without leaving anything in the floating state as this can contribute to power consumption.</p> <p>Also ensure that all unnecessary peripherals are disabled.&nbsp;</p> <p>Retaining any memory blocks can also cause unnecessary current consumption.</p> <p>In case you are using the LDO, this can also cause a bit more current draw than the DC-DC converters.</p> <p>If you still suspect something, you can use our power profiler kit or even verify with the <a href="https://devzone.nordicsemi.com/power/w/opp/2/online-power-profiler-for-bluetooth-le">online power profiler</a>.</p> <p>Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>
