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 particularly affected by temperatures below 0 °C
(32 °F).
