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
• Avoid dropping the cell phone. Dropping it, especially on a hard surface, can
potentially cause damage to the phone and battery. If you suspect damage to the
phone or battery, take it to a service center for inspection.
• 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.
• Follow battery usage, storage and charging guidelines found in the user’s guide.
• 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 use incompatible cell phone batteries and chargers. Some Web sites and
second-hand dealers, not associated with reputable manufacturers and carriers,
might be selling incompatible or even counterfeit batteries and chargers.
Consumers should purchase manufacturer or carrier recommended products and
accessories.
• 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). The battery should not
