After fully charging, disconnect the device from the charger. First unplug the charger from the
device, and then unplug it from the electric socket.
Do not remove the battery before removing the charger. This may damage 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.
Reducing the battery consumption
Your device provides various options that help you conserve battery power.
• When you are not using the device, switch to sleep mode by pressing the Power key.
• Activate power saving mode.
• Close unnecessary apps using the task manager.
• Deactivate the Bluetooth feature when not in use.
• Deactivate the Wi-Fi feature when not in use.
• Deactivate auto-syncing of apps.
• Decrease the backlight time.
• Decrease the screen brightness.
• When the battery power is low, the battery icon appears empty.
• 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.
• The device can be used while it is charging, but it may take longer to fully charge
the battery.
