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).
