Charge from a computer
You can use USB charging when a wall outlet is not available. Data can be transferred
while charging the device. The efficiency of USB charging power varies significantly, and
it may take a long time for charging to start and the device to start functioning.
1 First connect the USB cable to the computer, then to your phone.
2 When the battery is full, first unplug the USB cable from your phone, then from the
computer.
If the battery is completely discharged, it may take several minutes before the charging
indicator is displayed or before any calls can be made.
If the battery has not been used for a long time, to begin charging, you may need to
connect the charger, then disconnect and reconnect it.
Antenna locations
Avoid touching the antenna area while the antenna is in use. Contact with antennas
affects the communication quality and may reduce battery life due to higher power level
during operation.
