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 disconnecting from the network
or 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.
