Charge the battery over USB
Battery low, but you don't have a charger with you? You can use a compatible USB cable
to connect your phone to a compatible device, such as 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.
You can use your phone while it's charging.
To avoid breaking the charger connector, be careful when connecting or disconnecting
the charger cable.
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.
