Incident narrative

SaferProducts.gov consumer incident report 20260720-F433F-2147313659. Severity: No Incident, No Injury. Product: Samsung SM-Q500 (Samsung Galaxy Ring, Titanium Gold color, size 10. Model SM-Q500 AI Smart Ring. This is a wearable smart ring designed for continuous health and fitness tracking, including sleep monitoring, heart rate, and activity tracking. The ring is intended to be worn on the finger 24 hours a day.). Incident: I am reporting a Samsung Galaxy Ring (smart ring) because the internal battery has swollen, causing multiple cracks in the ring structure. While attempting to remove the ring from my finger, I discovered the battery had expanded significantly. The swelling forced the ring to crack in several places, and I had to use a lubricant to safely remove it. This is not an isolated quality issue. Both my ring and my spouses ring experienced severe and rapid battery degradation within the first year of ownership. My original ring failed completely and was replaced under warranty. The replacement ring has now developed the same dangerous swelling and cracking. The product was being used as intended -worn daily on the finger for health and activity tracking, including overnight while sleeping. No injuries have occurred at this time. However, a swollen lithium battery in a wearable device poses a serious risk of chemical leakage, thermal runaway, fire, or explosion. This is the primary reason I am reporting the product.
