on nrf52810 datasheet current consumption:1.5 µA at 3 V in System ON mode, with full 24 kB RAM retention, wake on RTC,But Online Power Profiler,Idle current 1.1µA.Idle current is not System ON mode current consumption?

    Hi

    There could be multiple reasons for this to occur, so it's impossible to say by your brief description. Are you measuring on a Development Kit or a custom board? What instrument are you using to measure the current consumption? There might be some current leakage somewhere on the board, as the OPP and PS values are measuring the chip by itself with nothing else drawing power. There could also be a pin that is shorted somewhere on your board.

    Best regards,

    Simon
