Swollen Galaxy Ring battery hospitalized a man after it got stuck

A viral post on X/Twitter shows a Samsung Galaxy Ring stuck on someone’s finger due to a swollen battery, which led to a missed flight and a hospital visit.

Ahhh…this is…not good.

My Samsung Galaxy Ring’s battery started swelling. While it’s on my finger 😬. And while I’m about to board a flight 😬

Now I cannot take it off and this thing hurts.

Any quick suggestions @SamsungUK @SamsungMobileUS? pic.twitter.com/LOO1kSlQUw

@ZONEofTECH (also known as Daniel)  posted a few images to the platform showing the ring with the swollen batteries on his finger while he was in line to board a flight. Daniel also added that he could not take it off and that it hurt. “Yikes.”

To add some context, Lithium-ion batteries can expand (or puff up) for several reasons, including heat, age, or being overcharged (I cooked a PSP battery by doing that once… whoops). Samsung has faced challenges with this issue in the past, as the Galaxy Note 7′s batteries started expanding and catching fire, resulting in the device being banned by the FAA and subsequently recalled and discontinued by Samsung due to the issue.

Close-up photos taken by Daniel show the inner portion of the ring where the battery is located, with the actual battery itself swelling and pushing into Daniel’s finger. Because the ring itself is made out of solid titanium, the battery doesn’t have anywhere to expand, nor does it bend in case of emergencies like this.

Update #2

Finally got home after way over 50h of flying/travelling 😅

Samsung reached out to me:
– refunded me for my overnight hotel
– booked me a car to get me home this morning
– collected the ring from me, for further investigation

My finger is also doing well, aside from… https://t.co/40c7l6MASV pic.twitter.com/xSSDc7Dz7J

A user on Reddit who also experienced battery swelling noted that the batteries are prone to overcharging if left on the charger for a long time past the point of being 100 per cent full. However, both instances of battery swelling happen while it is being worn, so heat could be a factor.

Daniel also mentioned that the battery had been acting strangely for months, and at one point, it didn’t even turn on when charged.

Users did point out that Daniel could potentially receive compensation from Samsung for the hospitalization and the ring becoming stuck on his finger, but Daniel noted that it was a review unit and that he had returned the device to Samsung. The tech giant refunded him for his overnight hotel stay and booked a car to take him home.
