Warning for Wearables: Swollen Battery in Samsung Galaxy Ring Forces Emergency Removal

Considering buying a smart ring? You might want to pause. A bizarre and alarming incident involving the Samsung Galaxy Ring has raised immediate safety concerns for the burgeoning wearable tech category.

A user reported that the battery inside their Galaxy Ring swelled up dramatically while still on their finger.

The incident had immediate, real-world consequences: the user was reportedly barred from boarding an airplane because the swollen device was deemed a fire hazard (hazardous material).

The situation escalated quickly, forcing the individual to seek medical attention.

The ring was so swollen that it had to be removed by doctors in a hospital. Accompanying photos clearly show the lithium-ion battery distending the ring’s casing from the inside.

A Unique Removal Hazard

This event highlights a specific danger unique to smart rings. Unlike traditional metal rings, which doctors can often cut or saw off a swollen finger, a smart ring cannot be simply dismantled.

Puncturing the casing of a swollen device risks damaging the internal lithium-ion battery, which could lead to a thermal event, potentially causing a significant burn right on the user's hand.

While the incident is unlikely to be severe enough to cause amputation, the danger of a serious burn from a ruptured, short-circuiting battery is very real.

The event serves as a stark reminder of the inherent risks when complex battery technology is miniaturized and worn directly against the skin, particularly with a product that cannot be easily removed in an emergency.
