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 devices 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.
During the initial setup after purchase or when restoring data

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
devices 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 devices temperature, the
device will turn off. Do not use the device until the devices 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 batterys lifespan, damaging the device, or causing a fire.
Do not store your device in very cold or very hot temperatures.
Do not expose your device to direct sunlight for extended periods.
Do not use or store your device for extended periods in very hot areas, such as inside a
car in the summertime.
Do not place the device in any areas that may overheat, such as on an electric heating
mat.
Do not store your device near or in heaters, microwaves, hot cooking equipment, or high
pressure containers.
Do not use a cable whose covering is peeled off or damaged, and do not use any charger
or battery that is damaged or malfunctioning.

Battery charging tips and precautions
If the battery is completely discharged, the device cannot be turned on immediately
when the charger is connected. Allow a depleted battery to charge for a few minutes
before turning on the device.
If you use multiple apps at once, network apps, or apps that need a connection to
another device, the battery will drain quickly. To avoid losing power during a data
transfer, always use these apps after fully charging the battery.
Using a power source other than the charger, such as a computer, may result in a slower
charging speed due to a lower electric current.
The device can be used while it is charging, but it may take longer to fully charge the
battery.
If the device receives an unstable power supply while charging, the touchscreen may not
function. If this happens, unplug the charger from the device.
