Samsung Galaxy Watch users report burns and battery failures
Galaxy Watch Owners Report Wrist Burns and Battery Failures
Several Samsung Galaxy Watch owners have reported circular red marks and alleged thermal burns directly under their devices’ sensor arrays, with affected units frequently suffering severe overnight battery drain, Kaitlyn Cimino reported for Android Authority.

The Tech TL;DR:
- Multiple users across Reddit and Android Authority reports have documented circular red marks, blistering, and severe overnight battery drain on Samsung Galaxy Watch models, including the Galaxy Watch 5 Pro.
- While contact dermatitis or moisture friction can cause similar skin irritations, fluid-filled blistering reported in some cases suggests potential thermal burns resulting from localized overheating.
- Samsung has not officially acknowledged any overheating defect tied to the issue, typically directing customers to review safety guidelines regarding strap tightness and device cleanliness.
Background on Hardware Incidents and Thermal Management
The complaints arrive as Samsung’s broader wearable lineup faces heightened scrutiny over thermal management. Recent iterations such as the Galaxy Watch 9 and Galaxy Watch Ultra 2 have experienced slow charging speeds driven by thermal throttling, prompting some users to deploy do-it-yourself charging fans to maintain optimal power delivery.
The current burn allegations, however, center on overnight wear rather than active power replenishment. Reddit user ksima_03 reported wearing a Galaxy Watch 5 Pro to bed with a full charge, waking up to a completely dead, unresponsive watch accompanied by a severe, burn-like mark on the wrist positioned directly underneath the sensor array.

Evaluating Hardware Overheating Versus Skin Irritation
Observers note that users often mistake common contact dermatitis for thermal injuries, as sweat, trapped moisture, and infrequent strap hygiene routinely create skin friction points beneath wearable devices. However, cases involving fluid-filled blistering complicate simple dermatitis explanations, pointing toward potential localized thermal output.
The observed pairing of dead batteries and localized skin damage indicates that rogue background processing routines might be generating intense heat in a concentrated area. Smartwatches typically feature built-in hardware safeguards designed to throttle performance or execute emergency shutdowns when internal temperatures exceed safe thresholds. The persistence of these unmanaged heat spikes suggests those safety routines may fail to trigger under specific background software anomalies.
Samsung Guides Users to Support and Safety Measures
Samsung has not issued a formal statement confirming an overarching hardware defect or recall related to watch-induced thermal burns. Customer service interactions regarding similar complaints currently guide users toward standard support documentation emphasizing correct strap tightness and routine sensor cleaning, alongside standard device inspection offers for suspected hardware malfunctions.
Anyone experiencing acute burning sensations, unexpected heat output, or sudden blistering beneath a smartwatch should remove the hardware immediately and reach out to official manufacturer support channels for formal evaluation.
