4. Battery information

Your device is powered by a rechargeable battery. The full
performance of a new battery is achieved only after two or
three complete charge and discharge cycles. The battery
can be charged and discharged hundreds of times but it
will eventually wear out. When the talk and standby times
are noticeably shorter than normal, buy a new battery. Use
only Nokia approved batteries, and recharge your battery
only with Nokia approved chargers designated for this
device.
Unplug the charger from the electrical plug and the device
when not in use. Do not leave the battery connected to a
charger. Overcharging may shorten its lifetime. If left
unused, a fully charged battery will lose its charge over
time. Temperature extremes can affect the ability of your
battery to charge.
