Hi, we did not find anything wrong in the smaller chunk of schematics that you posted. But we recommend you to check if there are any input pins unconnected and floating. This would cause power fluctuations. Apart from that it is hard to say without knowing your full project details, hardware/software

Here,

VDD = 3.3v

please send the schematics, so that our hardware expert can review it. What kind of power source are you testing with?

Yes, i use custom board. This is my nrf52810,

not the one you are using. I get 2.5mA not 4mA my mistake. 4mA is because there is microcontroller solder together on the board. I did disable as you told but still no changes.

Is there any other way to solve this?

I just tested this on 52810 DK and it shows that the average current is around 1mA

This tells me that you are using a custom board and most likely there is some issue there.

Hi, I did. But the current shows no different. Still 4mA.

I have not yet tested current consumption of this but quick look into the project files shows that the logs are enabled and using UART as backend, so this will consume some power. Disable them in sdk_config.h

Change below

#ifndef NRF_LOG_ENABLED
#define NRF_LOG_ENABLED 1
#endif

#ifndef NRF_LOG_ENABLED
#define NRF_LOG_ENABLED 0
#endif

*less than 1mA
