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.

•
If the device overheats or feels hot for a prolonged period, do not use it for a while. If
the device continues to overheat, contact a Samsung Service Centre.
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.
8
Basics
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.
•
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.
•
Never use a damaged charger or battery.
Maintaining water and dust resistance
Your device supports water- and dust-resistance. Follow these tips carefully to maintain the
water- and dust-resistance of your device. Failure to do so may result in damage to your
device.
•
Do not immerse the device in fresh water deeper than 1.5 m or keep it submerged for
more than 30 minutes. If you immerse the device in any liquid other than fresh water,
such as salt water, ionised water, or alcoholic beverage, liquid will enter the device faster.
•
Ensure that the back cover is tightly closed. Otherwise, it may not provide protection
from water and dust.
•
Do not immerse the device in water for extended periods.
•
Do not expose the device to water moving with force, such as running water from taps,
ocean waves, or waterfalls.
•
Do not open the device’s covers when the device is in water or in very humid places, such
as swimming pools or bathrooms.
•
Do not open the back cover using wet hands or when the device is wet.
•
The rubber seal fitted to the back cover is an important component of the device. Take
care when opening and closing the back cover to avoid damaging the rubber seal. Also,
ensure that the rubber seal is free from debris, such as sand or dust to prevent damage to
the device.
