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. 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) isnoticeably 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 batteryonly with Samsung-approved chargers. When a charger is not inuse, disconnect it from the power source. Do not leave the batteryconnected to a charger for more than a week, since overchargingmay 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 capacity andlifetime of the battery. Always try to keep the battery at roomtemperature. A phone with a hot or cold battery may temporarilynot work, even when the battery is fully charged. Li-ion batteriesare particularly affected by temperatures below 0 °C (32 °F). Do not short-circuit the battery. Accidental short- circuiting canoccur when a metallic object (coin, clip or pen) causes a directconnection between the + and - terminals of the battery (metalstrips on the battery), for example when you carry a spare batteryin a pocket or bag. Short-circuiting the terminals may damage thebattery or the object causing the short-circuiting. Dispose of used batteries in accordance with local regulations. Insome areas, the disposal of batteries in household or businesstrash may be prohibited. For safe disposal options for Li-Ionbatteries, contact your nearest Samsung authorized service center.Always recycle.
