the phone while it is charging.
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 unplug and reconnect it.
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 to a compatible device, such as a computer.
To avoid breaking the charger connector, be careful when connecting or
disconnecting the charger cable.

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.
