A Samsung Galaxy Ring reportedly malfunctioned on Monday, with its battery swelling so much that it got stuck on the user's finger. Rotar says he “won’t be wearing a smart ring ever again” after the experience. Why did the smart ring do this? If you experience a sudden drop in the battery life of any smart ring, remove it and contact the manufacturer. It may be a sign of a malfunctioning battery, and the manufacturer will be able to advise you on what to do next.
