Thank you Vidar Berg for your kindness. So I imagine we can just wait for PPK2 fw update, that's fine. Thank you very much

Hello,

The 35 mA peaks appear to be an measurement artifact caused by the PPK when it switches its measurement range from uA -> mA. I see similar results here. This is of course misleading if you try to estimate the peak draw of a system. The good news is that it doesn't not seem to have much if any impact on the total charge for an event.

I will report this internally.

It is like the current consumption during the phase labeled as "pre" in https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf52-online-power-profiler sometime is much higher. Like about 35mA instead of about 6mA
