Battery charging tips and precautions
Use only Samsung-approved battery, charger, and cable specifically designed for your
device. Incompatible battery, charger, and cable can cause serious injuries or damage to
your device.
•
Connecting the charger improperly may cause serious damage to the device. Any
damage caused by misuse is not covered by the warranty.
•
Use only USB Type-C cable supplied with the device. The device may be damaged if
you use Micro USB cable.
•
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.

Getting started
10
•
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.
•
When using a charger, it is recommended to use an approved wired or wireless
charger that guarantees the charging performance.
•
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.
•
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 the device is not charging properly, take the device and the charger to a Samsung
Service Centre.

Some services that require a network connection may not be available depending on
the service provider.
