https://devzone.nordicsemi.com/f/nordic-q-a/20121/periodic-current-during-waiting-eventHi I am measuring the current. I use SDK 12.2.0 , NRF52 and S132. I noticed that current was flowing even while device waits events. Device waits by sd_app_evt_wait(). It does not advertising. It does not use app_timer and other peripheral.en-USTelligent Community 13Fri, 03 Mar 2017 00:37:48 GMThttps://devzone.nordicsemi.com/thread/78353?ContentTypeID=1Fri, 03 Mar 2017 00:37:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:def57e08-ba0e-4057-80bc-50491dded31atalby<p>Thank you for your answer.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/78352?ContentTypeID=1Thu, 02 Mar 2017 11:39:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d883ee3c-9dcd-4f9d-bfdd-0b829d624afaStian R&#248;ed Hafskjold<p>Hi,</p> <p>These are refresh mode spikes. The chip does not wake up, it is the regulator charging up capacitors.</p> <p>From the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/power.html#concept">POWER chapter in the spec</a>:</p> <blockquote> <ul> <li>Auto-controlled refresh modes for LDO and DC/DC regulators to maximize efficiency</li> </ul> </blockquote> <p>The average current including these spikes should be about 2 µA (SD enabled with full RAM retension, and LFXO and RTC running)</p><div style="clear:both;"></div>
