Who is affectedOwners of Samsung Galaxy Watch models, especially the Watch 5 Pro, who wear their watch while sleeping.
What to do- 1Take the watch off right away if it feels hot, and do not charge it again.
- 2Check your wrist in the morning for redness, blisters or pain.
- 3Get medical care for any blisters or burns and contact Samsung support.
- 4Watch for a battery that drains very fast overnight, and stop wearing the watch if that happens.
A Galaxy Watch 5 Pro owner posted photos on Reddit of blisters and red marks on their arm, which they link to wearing the watch overnight. They say the watch was charged to full before bed. By morning the battery was dead, and the watch would not turn back on.
What we know
Red marks and irritation are not unusual for people who wear watches. They are usually called contact dermatitis, which is a skin reaction to something touching the skin. Blisters are new. 9to5Google notes that a lithium-ion battery that drains in a few hours gives off a lot of heat, so a burn is possible. The Watch 5 Pro has a 590mAh battery.
This is not the first report of its kind. Users have claimed suspected overheating on the Galaxy Watch Ultra, Watch Ultra 2, Watch 8 and a few other models. Battery problems have also affected the Galaxy Ring. Still, 9to5Google says Samsung's watches are mostly safe, and its own years of testing never produced overheating that marked skin.
Who can relax, and what to watch
Most owners have little reason to panic. This is one person's account, and no cause has been confirmed. It is also not known how many watches are affected, or whether a specific fault is behind it. The warning signs are a watch that feels hot or a battery that drains very fast overnight. The alert box above lists what to do if you notice either.
The takeawayIf your smartwatch feels hot or its battery vanishes overnight, take it off and stop using it, especially before sleep.
