FXMS3110 standby current

I'm using FXMS3110 digital 3-axis magnetometer in my devices (~50pcs). In some of my devices the standby current is higher than expected, because of the magnetometer high standby current. I assume the problem is that the I2C block (of the magnetometer) is in unstable/indefinit state. What is the correct shutdown process? (assuming we want to power off the I2C lines, but the VDD voltage remains on IC). Write 0x00 to CTRL_REG1 and after that? Is it relevant how do I set to LOW the I2C lines?
