Deep sleep Problems

void setup()
{
}
void  loop(){  
        Spark.sleep(SLEEP_MODE_DEEP,120);
}

Got 2 Spark core , while running this code i get 2.2 ma on the first core
and 0.7 ma on the second core .

Is it buggy the sleep mode still ? Please share your experience with me

@Gentmat, the accuracy of your multimeter will affect your measurements. Also, if you have anything connected to Vin or the 3.3V lines such as sensors, LEDs, etc. will affect the current draw.

I have nothing connected to the core, both of them are not connected to anything
