Incident Overview
A Reddit user identified as u/MaybeNotThrowing shared a troubling experience with his Samsung Galaxy Ring. After nine months of normal use, the ring’s battery began to swell, turning the device into a potential safety hazard.
User Timeline
The user purchased the Galaxy Ring shortly after its July 2024 launch. By April 2025, the battery stopped holding a charge. Despite the issue, he continued wearing the ring because he had grown accustomed to its feel.
When he attempted to charge the device later in the week, the connector no longer fit. Upon inspection, he discovered the ring had swollen significantly.
Safety Implications
Swollen lithium‑ion batteries can rupture, leak chemicals, or cause burns. Wearing a swollen smart ring amplifies the risk of finger injury.
- Stop using the device immediately.
- Do not attempt to charge or force a connection.
- Contact the manufacturer’s support line for a safe disposal or replacement.
Samsung’s Position
Samsung does not appear to be at fault in this specific case because the user could have replaced the battery under the device’s warranty. The company emphasizes that continued use of a known defective battery is unsafe and not recommended.
Legal Battle with Oura
Samsung is currently engaged in a patent‑infringement lawsuit against Oura, the market leader in smart rings. The litigation has delayed the launch of the Galaxy Ring 2, leaving consumers uncertain about the next generation’s availability.
What Consumers Should Do
If you own a Galaxy Ring or any smart wearable with a lithium‑ion battery, follow these guidelines:
- Monitor battery performance; replace it promptly if charge retention drops.
- Do not ignore physical changes such as swelling, discoloration, or heat.
- Utilize the warranty period for battery replacement or device repair.
- Stay informed about product recalls or safety notices from the manufacturer.
