180Section 13consumption depends on factors such as networkconfiguration, signal strength, operating temperature,features selected, frequency of calls, and voice, data, andother 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 usesless power; talk and standby time are greatly affected by thesignal strength on the cellular network and the parameters setby the network operator.• Battery charging time depends on the remaining battery chargeand the type of battery and charger used. The battery can becharged and discharged hundreds of times, but it will graduallywear out. When the operation time (talk time and standby time)is noticeably shorter than normal, it is time to buy a newbattery.• If left unused, a fully charged battery will discharge itself overtime.• Use only Samsung-approved batteries and recharge yourbattery only with Samsung-approved chargers. When a chargeris not in use, disconnect it from the power source. Do not leavethe battery connected to a charger for more than a week, sinceovercharging may shorten its life.• Extreme temperatures will affect the charging capacity of yourbattery: 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 capacityand lifetime of the battery. Always try to keep the battery atroom temperature. A phone with a hot or cold battery maytemporarily not work, even when the battery is fully charged.Li-ion batteries are particularly affected by temperatures below0 °C (32 °F).
