No matter what my wife does, the body battery on her device never goes above about 35 and her sleep tracking seems to be way off as well. She averages 8-10 hours sleep a night and usually she will be told that her sleep score is no higher than 40 most days...
On the other hand i have a Fenix 6 and i can get 5 hours sleep and be told my sleep score was 70
Is there much/anything that can be done to fix this?
