Battery Precautions
• 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 and the type of battery and 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).
