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 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
