Basic
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.
• 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 you charge the device while the multipurpose jack is wet, the device may be
damaged. Thoroughly dry the multipurpose jack before charging the device.
• If the device is not charging properly, take the device and the charger to a
Samsung Service Centre.
