RE: NRF9160DK & System OFF

So I managed to solve the issue myself, seems like the modem does not power off unless you call nrf_modem_lib_init() before lte_lc_power_off.
Now I'm reading an average of 2.54uA:

I just had to change my code to this:

#include <modem/lte_lc.h>
#include <modem/nrf_modem_lib.h>

int main(void) {
  nrf_modem_lib_init();
  lte_lc_power_off();
  k_sleep(K_MSEC(1000));
  NRF_REGULATORS->SYSTEMOFF = 1;
  return 0;
}

And my prj.conf to include nrf_modem_lib:

CONFIG_LTE_LINK_CONTROL=y
CONFIG_LTE_AUTO_INIT_AND_CONNECT=n
CONFIG_NRF_MODEM_LIB=y
