Samsung Galaxy Ring battery swells, owner requires ER removal

On Sept 29, 2025, YouTuber Daniel Rotar (Twitter/X: @ZONEofTECH) reported that the battery inside his Samsung Galaxy Ring began swelling while he was wearing the device, causing the ring to become stuck and painful. Rotar says he was denied boarding on a flight, sought emergency care, and had the ring removed at a hospital.

What happened

• The ring reportedly swelled on the inside surface as its internal battery failed, creating pressure on the finger.
• Attempts to remove the ring at the airport were unsuccessful; ice and medical lubricant reportedly helped during the successful removal at the hospital.
• Rotar said he was denied boarding and had to arrange a hotel stay as a result of the incident.

Samsung response

A Samsung spokesperson told reporters that customer safety is a top priority, that they are in direct contact with the user, and that incidents like this are extremely rare. Samsung suggested some removal methods (soap and water, submerging the hand in cold water) and directed users to their support resources: https://www.samsung.com/support.

Why this can happen

Like all devices with batteries, wearables can fail. When a lithium-based battery fails it can produce heat and trapped gases that cause swelling. While uncommon, swelling is a known failure mode for small rechargeable batteries.

Safety and removal tips

• Do not force or cut a device with a swollen battery — puncturing a battery can cause fire or chemical exposure.
• Try cold water or ice to reduce finger swelling before attempting removal.
• Use medical lubricants or gentle soap to help slide the ring off; avoid applying creams that can increase swelling without medical advice.
• If the ring cannot be removed, seek immediate medical assistance — emergency departments can remove rings safely.
• Contact the device maker’s support for guidance and report the incident.
