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
service provider.
• 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-approved batteries, and
recharge your battery only with Samsung-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.
