https://devzone.nordicsemi.com/f/nordic-q-a/36561/constant-high-power-consumption-in-low-power-mode-about-480-uaGood morning everyone, I read a lot of threads in the last week on this subject, but so far I was not able to find a solution to the problem. On a custom board we are developing, I am not able to reduce the power consumption below 480uA, when no peripheralen-USTelligent Community 13Fri, 20 Jul 2018 13:58:45 GMThttps://devzone.nordicsemi.com/thread/140851?ContentTypeID=1Fri, 20 Jul 2018 13:58:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d1d3d43f-6c34-499f-b32d-7acc510f5d4elbe<p>Hi Martin,</p> <p>thank you very much for this checklist, it will be useful for the future.</p> <p>As for the topic I opened, I found out after more digging that for some reason the SAADC was causing the problem.</p> <p>I was using a double buffered SAADC (using two disting channels from 2 sensors), and&nbsp;since starting&nbsp;the SAADC for the first time, the consumption increased at 470uA. I was of course calling the uninint and disable, clearing all the interrupts and doing all the things recommended here, but I was still unable to reduce the consumption.</p> <p>The solution I found is to use a single buffer and to read one channel, then the second one. I don&#39;t know if this is normal or not, but for me it works perfectly and I have now a consumption of less than 3uA when disconnected and not advertising.&nbsp;</p> <p>Thank you anyhow.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/140845?ContentTypeID=1Fri, 20 Jul 2018 13:32:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b9ad1ec2-505b-490f-8d5a-410e68231d86Martin Lesund<p>Hi Ibe,</p> <p>Please go through <a href="https://devzone.nordicsemi.com/b/blog/posts/optimizing-power-on-nrf52-designs" target="_blank" rel="noopener noreferrer">this checklist </a>on how to optimize power on nRF52 projects.</p> <p>Have you tried enabling and populating the DC/DC converter for example?</p><div style="clear:both;"></div>
