Slightly excessive current consumption after programming with J-Link

[CurtisHx]

I have the nRF52 dev board and a stand-alone Segger J-Link (not the one that's on the dev board) connected to the nRF52 through the Debug In header.

The firmware that gets downloaded puts the nRF52 into low-power sleep. All peripherals disabled with the RTC going. Interrupt is set to fire after 0x10000000 RTC ticks (a long time).

After programming and power cycling the board, I read 1.74uA average on a Tektronix 4050 DMM, which is expected. I'm powering the board with a bench supply set to 3.1v

However, if I just program the nRF52 without power cycling, the average current bumps up to 2.25uA.

Is this expected behavior?

Ok, I commented according to my knowledge on nRF51, sorry. On nRF51 i think it was about 2mA, but you said you are observing uA. I may be wrong then, sorry for misleading answer.
