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.
•
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 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 because of 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 touch screen
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 Center or an authorized service center.
