Overview

• British YouTuber Daniel Rotar reported that his Galaxy Ring’s battery swelled during boarding in Hawaii, leading the airline to deny him travel on safety grounds.
• Clinicians cooled his finger and used medical lubricant to remove the titanium ring without cutting it, avoiding the risk of igniting a damaged lithium‑ion cell.
• Rotar had noted a sharp drop in runtime to about 1.5 days from roughly a week, a symptom that can indicate battery damage.
• Samsung says such cases are extremely rare and that it is in direct contact with Rotar as it examines the incident, with no cause identified so far.
• Months of forum posts cite similar complaints, including swollen cells, deformed rings and shortened battery life, underscoring safety challenges with tight-fitting smart rings.
