If it feels uncomfortably hot, take it off and let it cool. If it heats up while charging, disconnect the charger and wait for the watch to cool completely before charging again. Persistent or recurring overheating is a reason to stop using it and contact Samsung support.
Why a Galaxy Watch can get hot
Calls and demanding features
Extended incoming or outgoing calls and features or apps that use more power can make a Galaxy Watch warm as battery consumption increases, according to Samsung Singapore’s watch-specific guidance. A temporary rise during intensive use does not, by itself, identify a fault.

Charging, setup, updates, and surroundings
Samsung’s broader Galaxy-device guidance also lists demanding apps, initial setup or data transfers, software updates, charging, hot surroundings, and direct sunlight as possible contributors to heat. These are potential causes, not a diagnosis of your watch. Guidance for other Galaxy devices describes an operating ambient range, but that should not be treated as a universal temperature limit for every Galaxy Watch; check the manual for your model.

What to do if your Galaxy Watch is hot
If it feels too hot while you are wearing it
- Remove the watch and stop using it.
- Let it cool completely before wearing or using it again. Do not try to cool it rapidly in a freezer or by immersing it in water.
- If it remains too warm to touch, or the problem keeps happening after it cools, contact Samsung support or a service centre.
Samsung’s temperature guidance advises stopping use until the device cools and seeking support if it remains too warm.
If it gets hot while charging
- Disconnect the charger.
- Close running apps and leave the watch alone until it has cooled completely.
- Before charging again, check the charging accessories for damage and confirm they are compatible with your exact watch model. Use an approved charger and cable.
- If the watch heats up again during charging, stop and contact Samsung support rather than continuing to test it.
Samsung gives these steps for a smartwatch that heats while charging and powering on in its watch troubleshooting instructions.

If heat appears during intensive use
Pause a long call or demanding app, and close apps you do not need. Reducing unused connectivity or screen brightness may also lower power use; the available settings vary by model. If the watch cools and the heat does not return during ordinary use, that pattern is consistent with temporary heating, but it is not proof that the device is fault-free.

What Galaxy Watch temperature warnings mean
Samsung’s US temperature guide says the first Galaxy Watch alert appears at 113°F. If the temperature keeps rising, a later warning may restrict calling and other functions; the guide describes an exception for incoming 911 calls under its stated conditions. A further warning may be followed by automatic power-off. Samsung says behavior and symptoms can vary by device and model, so 113°F is a threshold reported in this US guide—not a universal diagnostic temperature or a guarantee that every watch will show the same sequence.

When to contact Samsung
Stop wearing the watch and contact Samsung support or a service centre if it stays too hot after cooling, repeatedly overheats, or heats again after you resume normal use or charging. Include your exact watch model and describe when the heat occurs—during calls, another feature, charging, setup, or ordinary use. For model-specific warnings, charging accessories, or controls, use the support material for your watch and region. Samsung’s watch-specific article on heat during calls was last updated July 22, 2022; its core advice is to stop using a persistently hot watch and seek service if the issue continues.
