Fitbit Sense that is always on Sleep Mode keeps dying after 2 days

[amandaz45]

I got a Fitbit Sense 2 years ago because I was so over the Apple approach of their products getting crappy when the latest product releases, now I am getting annoyed because after only having my Fitbit sense for 2 years I am seeing performance issues with it. 
I keep my Sense on Sleep Mode all the time, and the battery is constantly dying, usually after 1-2 days of wearing. 
Everything is updated on it, I have uninstalled apps, no longer look at it for notifications or even logging workouts. 
so annoyed, someone please help if Fitbit will replace or if I just have to reshop around and try out a different brand.
