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 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.
 Dispose of used batteries in accordance with local regulations. In some areas,
the disposal of batteries in household or business trash may be prohibited.
For safe disposal options for Li-Ion batteries, contact your nearest Samsung
authorized service center. Always recycle. Do not dispose of batteries in a
fire.
