Remove the watch and let it cool. If it is hot while charging, disconnect the charger and wait for the watch to cool completely before charging again. If overheating continues, contact Samsung support or a service centre.
Why a Galaxy Watch may get hot
Some warmth can be temporary when the watch is working hard. Samsung says extended incoming or outgoing calls and power-intensive features or apps can increase battery use and make a Galaxy Watch warm. That does not, by itself, establish a fault.
Other possible contributors identified in Samsung’s general Galaxy-device guidance include demanding apps, initial setup or data transfers, software updates, charging, hot surroundings, and direct sunlight. These are possible causes, not a diagnosis of an individual watch. Samsung gives an ambient operating range of 32–95°F for the devices covered by its general guidance; check your specific watch’s manual rather than treating that as a universal Galaxy Watch limit. Samsung’s overheating guidance covers those broader factors.
What to do if the watch feels too hot while you’re wearing it
- Take it off. Do not keep wearing or using a watch that feels uncomfortably hot.
- Let it cool naturally. Wait until it has cooled completely before wearing or using it again. Avoid rapid-cooling methods such as putting it in a freezer or immersing it in water; Samsung’s guidance is to stop use and allow it to cool.
- Contact Samsung if the heat persists. If it remains too warm to touch or overheats again after cooling, stop using it and contact Samsung support or a service centre. Samsung’s watch-specific guidance says heat can occur during calls or power-intensive use, but advises service if the problem continues. Samsung Singapore’s Galaxy Watch guidance was last updated July 22, 2022.
What to do if it heats up while charging
- Disconnect the charger. If the watch heats while charging, unplug it from the charging setup.
- Close running apps and wait. Let the watch cool completely before trying to charge it again. Samsung gives this advice for a watch that heats while charging and powering on. Samsung smart watch shutdown troubleshooting describes the steps.
- Check the accessories. Do not use a damaged or incompatible cable, charger, or dock. Samsung recommends an approved charger and cable; confirm that any replacement is compatible with your exact watch model. Samsung’s general heat guidance discusses charging accessories.
- Escalate if it happens again. A suitable charger is relevant when the heat occurs during charging; it is not a remedy for persistent overheating in other circumstances. If the watch keeps getting hot, stop wearing it and contact Samsung support.
Reduce heat during routine use
If the watch warms during a long call or demanding task and then cools normally, pause that activity and close apps you do not need. Samsung’s general Galaxy guidance also recommends reducing unused connectivity and screen brightness; the available settings and labels vary by model. These steps may reduce active workload, but they are not a substitute for stopping use when the watch is uncomfortably hot.

What Galaxy Watch temperature warnings mean
Samsung’s US support guide says the first Galaxy Watch temperature alert appears at 113°F. If the temperature continues to rise, a later warning may disable calling and other functions; the guide notes an exception for incoming 911 calls under its stated conditions. A further warning is followed by automatic power-off. Samsung cautions that symptoms and behavior vary by device and model, so treat 113°F as the threshold reported in this US guide—not a universal diagnostic temperature or a guarantee that every model behaves identically. See Samsung’s temperature guidance.
When to get help
- The watch stays too warm to touch after you let it cool.
- It repeatedly overheats during ordinary use or after cooling.
- It heats while charging again after you have stopped, cooled it, and checked the charging accessories.
In those cases, stop wearing or charging the watch and contact Samsung support or a service centre. For exact warnings, controls, and operating limits, consult support information for your specific Galaxy Watch model and region.
