RE: Energy Consumption of nrf52832

This difference seems like the high frequency clock (HFCLK) is running in your application. Do you need the HFCLK for the multiprotocol functionalities? I recommend you use the register directly to control the HFCLK to turn it off when not needed at least.

if (!(NRF_CLOCK->HFCLKSTAT & CLOCK_HFCLKSTAT_SRC_Msk))

{

  NRF_CLOCK->TASKS_HFCLKSTART = 1;

  NRF_CLOCK->EVENTS_HFCLKSTARTED = 0;

  while (NRF_CLOCK->EVENTS_HFCLKSTARTED == 0);

}

As for your initial question, no the SoftDevice should not consume more power using the Timeslot API specifically.

This post explains just about everything there is to know about reducing current consumption, so I suggest you take a look to find the best ways to do this.

Best regards,
