Precautions when using
batteries
• Never use a charger or battery
that is damaged in any way.
• Use the battery only for its
intended purpose.
• If you use the phone near the
network's base station, it uses
less power. Talk and standby
time are greatly affected by the
signal strength on the cellular
network and the parameters set
by the network operator.
• Battery charging time depends
on the remaining battery
charge, the type of battery, and
the charger used. The battery
can be charged and discharged
hundreds of times, but it will
gradually wear out. When the
operation time is noticeably
shorter than normal, it is time to
buy a new battery.
• If left unused, a fully charged
battery will discharge itself over
time.
• Use only Samsung and Band &
Olufsen-approved batteries, and
recharge your battery only with
Samsung and Band & Olufsen-
approved chargers. Disconnect
the charger from the power
source when it is not in use. Do
not leave the battery connected
to a charger for more than a
week, since overcharging may
shorten its life.
• Extreme temperatures will affect
the charging capacity of your
battery: it may require cooling or
warming first.
• Do not leave the battery in hot
or cold places because the
capacity and lifetime of the
battery will be reduced. Try to
keep the battery at room
temperature. A phone with a
hot or cold battery may not
work temporarily, even when
the battery is fully charged. Li-
ion batteries are particularly
affected by temperatures below
0°C (32°F).
• Do not short-circuit the battery.
Accidental short-circuiting can
occur when a metallic object like
a coin, clip or pen causes a
direct connection between the +
and – terminals of the battery
(metal strips on the battery). For
example, do not carry a spare
battery in a pocket or bag where
the battery may contact metal
objects. Short-circuiting the
terminals may damage the
battery or the object causing the
short-circuiting.
• Dispose of used batteries in
accordance with local
regulations. Always recycle. Do
not dispose of batteries in a fire.
