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 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.

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 massage 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 the 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.
