After I flash the program to the NRF52 and do a reset (does not matter whether it is a soft reset or pin reset) the system (DK and my own board) will consume 3mA even after NRF_POWER-&gt;SYSTEMOFF=1. However, do I do a poweren-USTelligent Community 13Sat, 18 Nov 2017 12:29:05 GMThttps://devzone.nordicsemi.com/thread/107945?ContentTypeID=1Sat, 18 Nov 2017 12:29:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9eafbf68-5890-4981-b829-9ec3dc1315b2Matthias L. Jugel<p>I can confirm, after using the mentioned jlink script the power usage drops from 3mA to 30uA and down to 2uA after I disconnect the debugger completely (wires).

In order to reduce the power consumption you can try to reset the DIF using JLinkExe. See <a href="https://devzone.nordicsemi.com/question/178370/resetting-dif-to-reduce-interface-current-on-nrf52/?answer=178527#post-id-178527">this post</a>.</p> <p>Can you also post debugger type/version, JLink dll version, JLink FW version, nrfjprog version etc.?</p><div style="clear:both;"></div>
