Strange current spikes

Hi,

I'm using NRF52832 with SDK11.

In my program i do "sd_power_system_off();"

However, on some units i see arround 50-200uA avarage current and on some units it's even little more then that...

Can you please tell from the picture if the current spikes are from inside the CPU (maybe i forgot to turn off something ?!) but what can cause 15ms spikes ?!?!

Or do you have any other idea what can cause this behivier from the outside?!

B.r

Yuval.
