Battery Standby and Talk Time
Standby and talk times will vary depending on phone usage patterns and conditions.
Battery power consumption depends on factors such as network configuration,
signal strength, operating temperature, features selected, frequency of calls, and
voice, data, and other application usage patterns.
Battery Precautions
Ⅲ Never use any charger or battery that is damaged in any way.
Ⅲ Use the battery only for its intended purpose.
Ⅲ 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.
Ⅲ 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.
Ⅲ If left unused, a fully charged battery will discharge itself over time.
Ⅲ 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.
Ⅲ Extreme temperatures will affect the charging capacity of your battery:
it may require cooling or warming first.
Ⅲ 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).
Ⅲ 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.
