Swollen Galaxy Ring battery hospitalized a man after it got stuck

A viral X/Twitter post shows a Samsung Galaxy Ring getting stuck on someone's finger due to a swollen battery, resulting in a missed flight and a hospital visit.

Ahh… that's… not good.

My Samsung Galaxy Ring's battery has started to swell. While it's on my finger 😬. In the meantime, I'm about to board a flight 😬

Now I can't take it off and this thing hurts.

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

@ZONEofTECH (also known as Daniel) posted several images on the platform showing a swollen battery ring on his finger as he stood in line to board a plane. Daniel also added that he couldn't take it off and that it hurt. “Yes”.

To add some context, lithium-ion batteries can expand (or swell) for several reasons, including heat, age, or overcharging (I cooked a PSP battery by doing this once… oops). Samsung has faced issues with this issue in the past, such as with the Galaxy Note 7'.The batteries began to expand and catch fire, causing the device prohibited by the FAA And subsequently withdrawn and discontinued by Samsung due to this issue.

Close-up photos taken by Daniel show the inside of the ring where the battery is located, with the battery itself inflating and being pressed into Daniel's finger. Since the ring itself is made of solid titanium, the battery has nowhere to expand and will not bend in case of such emergencies.

Update #2

Finally got home after over 50 hours of flight/travel 😅

Samsung contacted me:
— they refunded my money for the night at the hotel
– ordered a car to take me home this morning
– took the ring from me for further investigation

My finger feels good too, except… https://t.co/40c7l6MASV pic.twitter.com/xSSDc7Dz7J

A Reddit user who also experienced battery swelling noted that batteries are prone to overcharging if left on the charger for a long time past the 100 percent fill level. However, both cases of battery swelling occur while the battery is being worn, so heat may be a factor.

Daniel also mentioned that the battery had been acting strange for months, and at one point wouldn't even turn on when charging.

Users noted that Daniel could potentially receive compensation from Samsung for his hospitalization and ring getting stuck on his finger, but Daniel noted that this was a test device and that he returned the device to Samsung. The tech giant reimbursed him for the night's hotel stay and ordered a car to take him home.
