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.
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.
