Precautions when using batteries
• Never use any 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 (talk
time and standby 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. When a
charger is not in use, disconnect it from
the power source. 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, such as in a car in summer or
winter conditions, as you will reduce the
capacity and lifetime of the battery.
Always try to keep the battery at room
temperature. A phone with a hot or cold
battery may temporarily not work, 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 (coin, clip or pen)
causes a direct connection between the
+ and – terminals of the battery (metal
