&lt;p&gt;I can find some guidelines in the&amp;nbsp;lis2dh12 on how to achieve low powe operations, but they all seem to be considerably less than the ~65uA you are measuring. From your description it seems you have 3 active devices here: &amp;quot;nrf52840 chip, a pressure sensor and an accelerometer&amp;quot;. Are you able to measure the power consumption to each of them to identify the current consumption of them individually?&lt;/p&gt;
