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

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 batte ry 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.

Dispose of used batteries in accordance with local regulations. In
