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.
You can use the phone while it's charging. For example, if connected to a compatible
computer, you can synchronise your phone.
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.
