Battery Charging
The battery is not fully charged when first unpacked. It takes three
charging-discharging cycles for the battery to reach its peak performance.
The battery can be charged and discharged hundreds of times. However,
the capacity of the battery will be reduced each time it is charged/emptied,
and it will eventually wear out. When the talk time and the standby time
are noticeably shorter than normal, replace the battery. Use original
batteries and charging devices only.
Unplug the charger from the outlet and the phone when not in use. Do not
leave a fully-charged battery connected to a charger because overcharging
may shorten the life of the battery.
If the battery is completely discharged, the charging may not start
immediately when you plug in the connector. Wait for 10 to 15 minutes for
the phone to begin charging.
Use the battery only for its intended purpose. Never use any charger or
battery that is damaged.
Do not short-circuit the battery. An accidental short circuit may occur
when a metallic object, such as a coin, clip or pen causes the direct
connection of the positive (+) and negative (-) terminals of the battery, for
example, when you carry a spare battery in your pocket or purse. Short
circuit may damage the battery and the connecting object.
Storage at too high or low temperatures will result in a gradual capacity
loss. As a result the operating time of your mobile phone may be
considerably reduced, even after the battery is fully charged.
