Okay, do you have an nRF52 series development kit you can measure current on with this device just to make sure we have the same point of reference? For example the system OFF sample here running on a DK can make sure the measuring device is correct: https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/samples/boards/nordic/system_off/README.html#nrf_system_off

Please upload what current consumption you see and what DK you're testing on. If this is expected/similar to what we see on the PPK we can move on to your board.

Best regards,

Simon

Hello Simonr, thanks for reply !

Device for measuring is of our own making, and at its heart is sitting INA229 chip. Here is measurement with nothing hooked in.

Here noise is < 2 uA so it shouldnt be problem of measuring method right ? There shouldnt be anything else on board consuming power.. maybe DWM module which is in deep-sleep (+ few nA)...

Regretably, I dont have PPK 2 at this time, so this is all i get... I didnt go to much detail of my settings and config because for past year i tried almost anything which I was able to find on internet... I have disabled everything i could... Im hoping we find some Kconfig which i didnt try or tried but didnt work ?

The idle power consumption here looks very noisy on your end, so can you share some details on how exactly you measure current here. Are you able to recreate the same consumption on a development kit with a similar application on it.

What device are you using for current consumption measurement here, and what is the accuracy of this device? Do you by chance have a Power Profiler Kit II to do current consumption measurements on? You are correct that an idle nRF52833 should be <5µA, depending on what settings you have enabled.

Best regards,
