User reports skin burns from Galaxy Watch 5 Pro

A Galaxy Watch 5 Pro user shared images on Reddit showing redness and blisters on their wrist under the watch's sensors. The user said they wore the watch all night after a full charge, but upon waking, the battery was empty and the watch wouldn’t power on.

Similar complaints found online

Android Authority, a specialized website, noticed this report on October 21 and found similar complaints about Galaxy Watches on other platforms. The user’s case is the only one that clearly shows blisters, but the described situation is still plausible.

Battery and overheating concerns

The Galaxy Watch 5 Pro, launched in August 2022, has a large 590 mAh battery. However, draining it completely in one night suggests the watch may have run at full capacity for hours, potentially generating significant heat against the skin.

Possible cause of the issue

Android Authority suggests a background process might have gone out of control, causing excessive heat in a small area. This could explain both the empty battery and the burn. However, safety features should have prevented the watch from overheating.

Other models also affected

Android Authority found six other complaints about similar red circles under the sensors on different models, including the Galaxy Watch 7, Watch 8, and Watch Ultra 2. Some cases may be skin irritation, but blisters suggest burns.

Samsung’s history with overheating

Samsung has had battery issues in the past, including with the Galaxy Ring in 2025. The latest models, like the Galaxy Watch 9 and Watch Ultra 2, have also had overheating concerns, prompting some users to build their own cooling solutions.

Samsung’s response and advice

Samsung has not acknowledged overheating defects in its watches. Customer service typically advises tightening the band, cleaning, and inspecting suspected devices. The company also recommends removing the watch during long wear or sweating and letting the skin rest if irritation occurs.

Other brands with similar issues

Samsung is not the first brand to face such complaints. In 2014, LG G Watch users reported burns from metal charging connectors. In 2022, a class action lawsuit accused Fitbit of potential burns from its devices.

What users should do

If a watch drains quickly or causes burns, users should check power consumption settings and remove the watch immediately. Clean the skin and watch regularly, and contact Samsung support with photos of any marks or the device itself.
