4 steps
A phone that becomes unusually hot may be experiencing heavy workload, environmental heat, charging issues, or a battery or hardware problem. Knowing how to cool the device safely can help protect its battery and components. This article explains common causes of overheating, safe cooling steps, and warning signs that may require technical support.
Why does a phone get hot?
Moderate warmth can be normal during demanding activities such as gaming, video streaming, navigation, charging, or software updates. Excessive or persistent heat may be related to heavy background activity, a hot environment, charging accessories, battery problems, or other hardware issues.
When is overheating a concern?
Warning signs include a temperature alert on the screen, repeated unexpected shutdowns, a swollen battery, unusual odors, smoke, or a device that becomes extremely hot and does not cool after use stops. A swollen or damaged battery should not be pressed, punctured, or charged; stop using the device and seek qualified service.
How to cool your phone safely
Stop demanding activities, disconnect the charger if appropriate, remove an insulating case, and move the phone to a shaded and ventilated area. Let it cool naturally. Do not place the device in a refrigerator or freezer, and avoid rapid temperature changes that can cause condensation.
How to prevent overheating
Avoid prolonged exposure to direct sunlight or hot enclosed spaces, use compatible charging accessories, keep the operating system and apps updated, and reduce demanding activities when the phone becomes unusually hot.
When to seek technical support
Seek qualified technical support if overheating continues during light use, the phone repeatedly shuts down because of temperature, the battery is swollen or damaged, or you notice smoke, unusual odors, or other signs of hardware failure.
