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.
5
Basics

the functions and apps you use, these examples may not apply to your model.
•
During the initial setup after purchase or when restoring data

•
Keep the device updated with the latest software.
•
Conflicts between running apps may cause the device to heat up. Restart the device.
•
Deactivate the Wi-Fi, GPS, and Bluetooth features when not using them.
•
Close apps that increase battery consumption or that run in the background when
not in use.
•
Delete unnecessary files or unused apps.
•
Decrease the screen brightness.
•
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.
Device limitations when the device overheats
When the device heats up, the features and performance may be limited or the device may
turn off to cool down. This feature is only available on supported models.
•
If the device becomes hotter than usual, a device overheating message will appear. 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 you will only be
able to make emergency calls until the device cools down.
•
If the device overheats or feels hot for a prolonged period, a power off message will
appear. Turn off the device, and wait until it cools 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.
•
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.
7
Basics
•
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 water deeper than 1.5 m or keep it submerged for more
than 30 minutes.
•
Ensure that the back cover is tightly closed. Otherwise, it may not provide protection
from water and dust.
•
Do not expose the device to water moving with force.
•
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.
•
If the device is exposed to clean water, dry it thoroughly with a clean, soft cloth. If the
device is exposed to other liquids, such as salt water, ionised water, or alcoholic beverage,
rinse it with clean water and dry it thoroughly with a clean, soft cloth. If you do not follow
these instructions, the device’s performance and appearance may be affected.
•
The back cover may be loosened if the device is dropped or receives an impact. Ensure
that all the covers are properly aligned and tightly closed.
•
If the device has been immersed in water or the microphone or speaker is wet,
sound may not be heard clearly during a call. Wipe the device with a dry cloth or dry it
thoroughly before using it.
8
Basics
•
The touchscreen and other features may not work properly if the device is used in water.
•
Your device has been tested in a controlled environment and certified to be waterand dust-resistant in specific situations (meets requirements of classification IP68 as
described by the international standard IEC 60529-Degrees of Protection provided
by Enclosures [IP Code]; test conditions: 15-35 °C, 86-106 kPa, 1.5 metre, 30 minutes).
Despite this classification, it is still possible for your device to be damaged in certain
situations.

Basics
Charging the battery
Charge the battery before using it for the first time or when it has been unused for extended
periods.
Use only Samsung-approved chargers, batteries, and cables. Unapproved chargers or
cables can cause the battery to explode or damage the device.
Connecting the charger improperly may cause serious damage to the device. Any
damage caused by misuse is not covered by the warranty.
To save energy, unplug the charger when not in use. The charger does not have a
power switch, so you must unplug the charger from the electric socket when not in
use to avoid wasting power. The charger should remain close to the electric socket
and easily accessible while charging.
Connect the USB cable to the USB power adaptor, and plug the USB cable into the
1
device’s multipurpose jack.
Plug the USB power adaptor into an electric socket.
2
After fully charging, disconnect the device from the charger. First unplug the charger

Battery charging tips and precautions
•
When the battery power is low, the battery icon appears empty.
•
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.
15
Basics
•
While charging, the device and the charger may heat up. This is normal and should not
affect the device’s lifespan or performance. If the battery gets hotter than usual, the
charger may stop charging.
•
If you charge the device while the multipurpose jack is wet, the device may be damaged.
Thoroughly dry the multipurpose jack before charging the device.
•
If the device is not charging properly, take the device and the charger to a Samsung
