Some posts and links to follow:

And from this post, note however these forum replies are for Nordic nRF5x family parts:

Looking now more closely at nRF9160 System in Package (SiP):

Oh and a note on nRF9160 watchdog timer:

^ nRF9160 Sleep Mode Forum Posts
nRF9160 sleep mode not working in SDK 'nrf' v1.6.1, works in 1.7.0 . . .

Excerpts from this post:
-
"In order to achieve the lowest possible current consumption, logging has to be turned off. This is done by,
Adding the CONFIG_SERIAL=n flag to the prj.conf file in the project folder.
Adding the CONFIG_SERIAL=n to the SPM prj.conf file. This is located in the SDK_ROOT/nrf/samples/nrf9160/spm folder."
