Yes, There is no problem with DC-DC enable. As i advertise at every 1 sec, i can see normal peak of ~70 uA at every 1 sec. As of now we are going to use DC-DC enable this problem is not issue.

You don't see the problem when you have enabled the DC-DC ?

Thanks Sigurd for your valuable support. Here I use below code in the initialization. /* Configure default GPIO status / for(pinCntr = 0; pinCntr <= 30; pinCntr++) { / Default configuration of all GPIOs are Input and disconnected */

	NRF_GPIO->PIN_CNF[pinCntr] = (GPIO_PIN_CNF_SENSE_Disabled << GPIO_PIN_CNF_SENSE_Pos) \
                                    | (GPIO_PIN_CNF_DRIVE_S0S1 << GPIO_PIN_CNF_DRIVE_Pos) \
                                    | (NRF_GPIO_PIN_NOPULL << GPIO_PIN_CNF_PULL_Pos) \
                                    | (GPIO_PIN_CNF_INPUT_Disconnect << GPIO_PIN_CNF_INPUT_Pos) \
                                    | (GPIO_PIN_CNF_DIR_Input << GPIO_PIN_CNF_DIR_Pos);
}

One more thing to consider is that if i enable DC-DC than things go smoothly.

This type of slowly up-down floating of the current consumption is typically a result of a floating input pin. You should check if you have a floating input-pin somewhere.
