Please take a close up photo show how you do current measurement. Which firmware did you use ? Please try to test with the example\peripheral\rtc example and check which current consumption you have . Excluding the current consumption from the LED it should be about 3-4uA.

I have done power off and On,still the same continues.Actually i connected custom board to NRF52 DK.with connections like swdio,swclk,reset,Vcc,GND.

Hi MVR,

Have you made sure you do a power reset of the chip after you program it ? Otherwise it will stay in debug mode and you will see about 2mA consumption.

I disabled both UART and NRF_LOG,Still the power consumption is 2.2mA.

What peripherals are you using? I noticed that if the UART peripheral is enabled the power consumption increases to around 2.2mA.
