https://devzone.nordicsemi.com/f/nordic-q-a/7196/typical-current-consumption-for-port-gpiote-interruptsHello What is a typical current draw when using a PORT GPIOTE interrupt? I seem to be drawing approximately 200uA with a port event enabled. Is this normal? I&#39;m using a custom nRF51 board and when I send the device to SYSTEMOFF mode, disable allen-USTelligent Community 13Fri, 22 May 2015 11:21:20 GMThttps://devzone.nordicsemi.com/thread/25437?ContentTypeID=1Fri, 22 May 2015 11:21:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2d411acb-4c03-494b-bd52-0d0484b85dd2Stefan Birnir Sverrisson<p>Hi kilianod</p> <p>8 uA is very high for System Off mode. You should be getting ~0.6uA. Why do you expect 8uA?</p> <p>The first step is to try code that is proven to work, in order to identify if the problem is related to your hardware or if it is a software problem. Try to run the <a href="https://github.com/NordicSemiconductor/nrf51-powerdown-examples/blob/master/system_off_wakeup_on_gpio/main.c">system_off example</a>. If the chip still draws high current when running the system_off example, then the problem is hardware related. Try to go through the &quot;troubleshooting&quot; section in the current consumption guide in order to spot any potential problems. If you get the expected current consumption with the system_off example, then the problem is software related.</p> <p>Try also the <a href="https://github.com/NordicSemiconductor/nrf51-powerdown-examples/blob/master/system_on_wakeup_on_gpio/main.c">System_on example</a> which includes configuring a wakeup pin and sets up the PORT event. The expected currrent consumption when sleeping is ~2.6uA. The PORT event itself should not consume any noticable current, i.e. &lt;&lt;1uA.</p><div style="clear:both;"></div>
