Health and safety information
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
the battery is fully charged. Li-ion batteries are
