#4 how to Charging the battery?
Charge the battery before using it for the first time or when it has been unused for extended periods.
Only use a Samsung-approved battery, charger, and cable specifically designed for your device. An incompatible battery, charger, or 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.
Only use a USB Type-C cable like the one supplied with the device. The device may be damaged if you use a 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.
