We&#39;re evaluating the lowest power modes of our custom hardware to make sure there are no unknown sources of leakage. Our observation is that with the nRF9160en-USTelligent Community 13Tue, 28 Sep 2021 13:11:57 GMThttps://devzone.nordicsemi.com/thread/331527?ContentTypeID=1Tue, 28 Sep 2021 13:11:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:801d894a-860e-4919-a85b-27ac8204a261Kenneth<p>Enabling a peripheral will typically increase current consumption, the amount will depend on the system state and possible other peripherals that are enabled or active at the same time. 13uA seems reasonable.</p> <p>Kenneth</p><div style="clear:both;"></div>
