Thanks Kazi! That makes sense. On the nRF9160-DK it is disabled by default.

Hello,

I have run your sample on nRF52840 DK. UART1 was also enabled (which you can find from zephyr.dts file from build folder). After disabling the UART1, it shows expected output current (average 3.52uA).

you need to create an overlay file (nrf52840dk_nrf52840.overlay) with the following content and build the program again. You should get the expected current now.

&uart1 {  
     status = "disabled";
    };

Thanks.

Best Regards,
