Health and Safety Information 72Battery Standby and Talk TimeStandby and talk times will vary depending on phone usagepatterns and conditions. Battery power consumption depends onfactors such as network configuration, signal strength, operatingtemperature, 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 hardsurface, can potentially cause damage to the phone and battery. If yoususpect damage to the phone or battery, take it to a service center forinspection.• 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 lesspower; talk and standby time are greatly affected by the signalstrength on the cellular network and the parameters set by thenetwork operator.• Follow battery usage, storage and charging guidelines found in theuser’s guide.• Battery charging time depends on the remaining battery charge andthe type of battery and charger used. The battery can be charged anddischarged hundreds of times, but it will gradually wear out. When theoperation time (talk time and standby time) is noticeably shorter thannormal, 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 onlywith 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 Websites and second-hand dealers, not associated with reputablemanufacturers and carriers, might be selling incompatible or evencounterfeit batteries and chargers. Consumers should purchasemanufacturer 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 insummer or winter conditions, as you will reduce the capacity andlifetime of the battery. Always try to keep the battery at roomtemperature. A phone with a hot or cold battery may temporarily notwork, even when the battery is fully charged. Li-ion batteries areparticularly affected by temperatures below 0 °C (32 °F). The batteryshould not be charged at temperatures below 0 degrees C (32 degreesF) or above 45 degrees C (113 degrees F).• Do not place the phone in areas that may get very hot, such as on ornear a cooking surface, cooking appliance, iron, or radiator.• Do not get your phone or battery wet. Even though they will dry andappear to operate normally, the circuitry could slowly corrode andpose a safety hazard.
