A user reports on Reddit about an unusual incident with his Samsung Galaxy Watch 5 Pro: He claims he wore the smartwatch overnight and woke up the next morning with reddened skin and blisters on his wrist. At the same time, the previously fully charged battery was dead. According to him, the watch could no longer be turned on.
Was the Battery the Cause?
The combination of a dead battery and the described skin injury initially suggests a technical defect might be present. However, it is unclear whether the Galaxy Watch actually overheated significantly. A watch that becomes hot enough to cause blisters would likely wake a sleeping user quickly.
Skin irritations can certainly occur with prolonged wear of a smartwatch. However, blisters, as the Galaxy Watch is said to have caused, are much more unusual. The user himself considers a sudden intolerance unlikely. According to him, he had been wearing the watch for about three years.

Do Not Continue Using Defective Batteries
There are no indications of a fundamental problem with the Galaxy Watch 5 series from this single report. Nevertheless, users should take changes in the battery seriously. If a smartwatch suddenly discharges very quickly, becomes unusually hot, or the case swells, the device should not be used or charged further. In such cases, it is advisable to have it checked by a professional service or disposed of properly.
