LSM6D3H occasional excessive current

When the force sensor is powered off the LSM is always on and the microcontroller is in sleep mode.  Sometimes the battery will drain to empty.  When powered back up the LSM gets hot although it still works.  We usually replace it and all is good.  It connects to the CPU via SPI, SCX/SDX are GND, CS_AUX and INT2 float. The LSM connections look good, no shorts.  I have one now that got hot.  I removed the battery and reinstalled it, power cycled and the LSM did not get hot and hasn't since then.  Is there something we should do, command wise, before entering power down?  Have you seen this before?

Thanks,
Tom
