Power consumption of BQ27621

Hi TI, 

I have a question about the power consumption of BQ27621: We created a test PCB with this gauge, necessary capacitors and 10 kOhm pull down resistor at BIN, after that we connected VBAT and GND and measured the average supply current. It was about 70 uA, but the datasheet says that the maximum supply current is 27 uA, Why such a big difference in values?
