Accelerometer motion detection battery drain

Hello,

 

I am using the MMA8451Q accelerometer in a device and I want to check if that device is being used by someone. So I thought of using the accelerometer's motion detection to read and send an interrupt whenever the device moves. Before I get into the calibration and setting the bytes, I wanted to know if doing this would drain the battery. If this can be done, how long would a 100mAH battery last?

 

Thank you.

Best Regards.
