I could recommend that you check the errata list for the nrf52. There are some issues with the timer for example that can lead to high current (see link). Might be something that you could check there. This case might also be helpful.

We are using power tool to measure the current. I not checked with the online PPK.

How are you measuring the current? Have you checked the online PPK to see what your current should be roughly given your use case?

Hi Bjorn,

Thanks for the reply.

I already look into that same post. And I checked all the things what ever mentioned in that post ,we already considered those things. still it's consuming 20 micro Amps.

I would take a look at this great devzone post on how to reduce current consumption. Even though it is written for the nrf51, a lot of it still applies to the nrf52 series.
