Device overheating situations and solutions

When the device heats up while charging the battery

While charging, the device and the charger may become hot. During wireless charging or fast

charging, the device may feel hotter to the touch. This does not affect the device’s lifespan or

performance and is in the device’s normal range of operation. If the battery becomes too hot,

the charging speed may decrease or the charger may stop charging.

Do the following when the device heats up:

•

Disconnect the charger from the device and close any running apps. Wait for the

device to cool down and then begin charging the device again.

•

If the lower part of the device overheats, it could be because the connected USB

cable is damaged. Replace the damaged USB cable with a new Samsung-approved

one.

•

When using a wireless charger, do not place foreign materials, such as metal objects,

magnets, and magnetic stripe cards, between the device and the wireless charger.

The wireless charging or fast charging feature is only available on supported models.

When the device heats up during use

When you use features or apps that require more power or use them for extended periods,

your device may temporarily heat up due to increased battery consumption. Close any

running apps and do not use the device for a while.

The following are examples of situations in which the device may overheat. Depending on

the functions and apps you use, these examples may not apply to your model.

Precautions for device overheating

If you begin to feel uncomfortable due to the device overheating, stop using the device.

When the device heats up, the features and performance may be limited or the device may

turn off to cool down. The feature is only available on supported models.

•

If the device overheats and reaches a certain temperature, a warning message will appear

to prevent device failure, skin irritations and damages, and battery leakage. To lower the

device’s temperature, the screen brightness and the performance speed will be limited

and battery charging will stop. Running apps will be closed and all calling and other

features will be limited, except for emergency calls, until the device cools down.

•

If a second message appears due to a further increase of the device’s temperature, the

device will turn off. Do not use the device until the device’s temperature drops below the

specified level. If the second warning message appears during an emergency call, the call

will not be disconnected by a forced shut down.

Precautions for operating environment

Your device may heat up due to the environment in the following conditions. Use caution to

avoid shortening the battery’s lifespan, damaging the device, or causing a fire.

•

mat.
