• 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,
including 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).
