SmartSense Motion Sensor Battery Life

I setup my SmartThings hub and SmartSense motion sensor over this last weekend inside my porch next to a window and so far everything seems to be working correctly. I live in MN so the porch is fairly chilly and the temperature is reading in the 20 degrees which is expected. What is not expected though is that the battery life is reading at 88% already. Is this normal? Thanks!
