The precautions regarding battery charging tips and precautions for the SAMSUNG SM-A145F-N are:

• 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 Centre or an authorised service centre.
