• 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).
• 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 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-circuiting.
