https://devzone.nordicsemi.com/f/nordic-q-a/6103/power-consumption-in-idle-mode-1-2maI am using nRF51422 with a 16MHz crsytal, HMC5893, LED and MPU6500. I have noticed that the power consumption in IDLE mode is approx 1.2mA. This was originally at 6mA. I call the function sd_power_system_off() within my main program.

I guess the extra comsuption might come from the 16MHz crystal, and the reasons could be like that:</p> <p>1.the timer is still working</p> <p>2.the GPIOTE does not disable</p> <p>both of them will keep the 16MHz crytal working and cause about 1mA.</p><div style="clear:both;"></div>
