S1 Pro battery draining when not in use

The original message follows below.
I have two S1 Pro speakers. Same age, both pretty much new. The latest one i purchased with only a few hours of use has a battery that slowly dies over the course of a week or two when not in use. The other S1 Pro battery lasts as it should. Any thoughts?
