 Using the RTC example in the &amp;#39;nRF5 SDK 16 / examples / peripheral&amp;#39; as a starting point, we&amp;#39;ve programmed the rtc_handler to execute at regular intervals approx. every 1 millisecond. With an empty rtc_handler, the average current consumption is about</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Tue, 16 Jun 2020 17:30:55 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/62617/nrf52840-low-power-mode-current-consumption" /><item><title>RE: nRF52840 Low Power Mode Current Consumption</title><link>https://devzone.nordicsemi.com/thread/255348?ContentTypeID=1</link><pubDate>Tue, 16 Jun 2020 17:30:55 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:22bcbca9-f44c-4bff-a92b-bb58adbf6c9e</guid><dc:creator>NordicEmb20</dc:creator><description>&lt;p&gt;Thank you for your answer, Kenneth!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nRF52840 Low Power Mode Current Consumption</title><link>https://devzone.nordicsemi.com/thread/255218?ContentTypeID=1</link><pubDate>Tue, 16 Jun 2020 10:52:32 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:86f4fd14-7f0a-4c18-b2d8-3cedc0b09f37</guid><dc:creator>Kenneth</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;If you wakeup every 1ms, then even with a empty callback handler the system would still need to wakeup, run the exception handler, call the callback, calculate the next wakeup, return to main and go to sleep. If we presume this take 20us and require 4mA; 4mA *0.020/1 = 80uA on average. To reduce the most efficient would be to wakeup more rarely.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;br /&gt;Kenneth&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
