• Battery charging times depend 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 life-time 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 strips
on the back of the battery), for example when
you carry a spare battery in a pocket or bag.
Short-circuiting the terminals may damage the
battery or the object causing the short-circuit.
