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 touch-
screen may not function. If this happens, unplug the charger from the
device.
