Save energy
When you have fully charged the battery and disconnected the charger from the device,
remember to also unplug the charger from the wall outlet.
You do not need to charge your battery so often if you do the following:
● Close and disable applications, services, and connections when you are not using
them.
● Decrease the brightness of the screen.
● Set the device to enter the power saver mode after the minimum period of inactivity,
if available in your device.
● Disable unnecessary sounds, such as keypad tones. Set the volume of your device to
an average level.
