For the ~ 3 months that I have owned the 2018 versions of the Samsung Sensors, the multipurpose sensor has consumed the most battery energy compared to the motion and leak sensors. This is in a mainly empty vacation home, All are at about 50 degrees ambient temperature. There is roughly 70 % battery reading for the two multipupose sensors, and 90% + for the 3 leak and 1 motion sensors. One of my multipurpose sensors is sitting in a crawl space, so there is no opening or closing as well as motion, so i can not explain the comparatively increase battery consumption.
I would try a leak sensor if you are insistent on using a samsung sensor and worried about battery life. I would also add that possibly the motion sensing inside a freezer opening and closing may be a source of increased energy consumption of the sensor.
