Battery
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.
•
Use only USB Type-C cable supplied with the device. The device may be damaged
if you use Micro USB cable.
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.

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.
