Watch will not turn on or respond unless connected to the charger

[Esrohr]

About every two days my charge five stops responding to my arm motion or double taps to wake it up.  If I connect the charger sometimes I can get it to work again.  Today nothing works.  On the charger it works.  As soon as I disconnect the charger the screen goes black.  I removed the charge five from the app and restored it.  Phone and watch paired and synced but when I disconnect the charger screen goes black and watch doesn’t respond.  A couple of times I was able to disconnect and the time screen responded but when I put it on my wrist it was back to not responding.  I am so frustrated that I just want to return this.
