TL;DR A Galaxy Ring user says the battery swelled while the device was on their finger, leaving it stuck and painful.
The user was denied boarding a flight and had the ring removed in the hospital using ice and medical lubricant.
Photos of the ring after it was removed show a visibly distorted battery.
Update: September 30, 2025 (12:05 AM ET): Tech creator Daniel has shared his theory on what may have caused his Galaxy Ring to fail. He suspects the battery could have been damaged by Hawaii’s intense heat (where he attended the Snapdragon Summit), exposure to salt water, multiple flights, or an already faulty battery.
Of these possibilities, salt water exposure seems the most likely culprit. The Galaxy Ring is not designed to withstand it. Its 10ATM water resistance and IP68 rating don’t protect against the corrosive effects of salt water.
Daniel also noted that his ring had been struggling with battery life even before the swelling incident, lasting only about 1.5 days instead of the seven-day battery life he was getting from it initially. By the time the ring supposedly expanded, the battery was completely drained.
Samsung has yet to publicly respond to Daniel’s posts on X, so it remains unclear what steps the company might take. We’ll update this story if and when Samsung issues a statement.

In his first post, he wrote that the swelling began while he was about to board a flight. He added that the ring hurt and couldn’t be taken off, tagging Samsung accounts for help.
