Charging the battery
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.
