Charging

This phone is charged through the µUSB interface only (there is no separate connector for a charger). Supported
are two charging modes for normal USB2.0 charging and Nokia uUSB AC-50 charger. Charging is controlled by
energy management, and external components are needed to protect the baseband module against EMC, reverse
polarity and transient frequency deviation.

Normal and extreme voltages

In the table below normal and extreme voltages are shown, when a BP-3L battery is used.

Lower extreme voltage
Higher extreme voltage(fast charging)

USB

In this phone the USB connector is the only physical connector, which means that the USB port is used both for
data transfer as well as for charging. The USB 2.0 is supported with full speed (12 Mbps). It also supports hot
swap, which means that USB devices may be plugged in/out at any time. This phone is provided with a specific
connector for USB.
