My Vivoactive 3 was not charging a few days ago. I cleaned the connection with a cotton swab and rubbing alcohol as I always have in the past when I’ve had this problem. It charged to 100%. Today, I connected to the charger again but while it was plugged in and showing it was charging, it went from 36% to 3% battery life in a short time. I can’t get it to charge while plugged in.
