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.
1 Connect the USB cable to the USB power adapter, and then plug the end of the USB cable
into the multipurpose jack.
Connecting the charger improperly may cause serious damage to the device. Any
damage caused by misuse is not covered by the warranty.
2 Plug the USB power adapter into an electric socket.
3 After fully charging, disconnect the device from the charger. First unplug the charger
from the device, and then unplug it from the electric socket.
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 the charger is connected. Allow a depleted battery to charge for a few minutes
before turning on the device.

another device, the battery will drain quickly. To avoid disconnecting from the network
or losing power during a data transfer, always use these apps after fully charging the
battery.

Using a power source other than the USB power adaptor, such as a computer, may result
in a slower charging speed due to a lower electric current.
