I have a new Vivoactive 4S for Christmas 2020 it has about a 10 hour battery life even without any activities and all things turned off except heart rate monitor. I understand there is an engineering fix being looked at. But I want to know if there is any news? I have tried everything, and have exchanged for a new one, same issue. Very disappointed. Garmin please help. I read older posts about same issue, said to mention Garmin-AmberD.
