Health and Safety Information 146
• 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 leave the battery
connected to a charger for more than a week, since overcharging may
shorten its life.
• 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. If
unsure about whether a replacement battery or charger is compatible,
contact the manufacturer of the battery or charger.
• Misuse or use of incompatible phones, batteries, and charging devices
could result in damage to the equipment and a possible risk of fire,
explosion, leakage, or other serious hazard.
• 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 place the phone in areas that may get very hot, such as on or
near a cooking surface, cooking appliance, iron, or radiator.
• Do not get your phone or battery wet. Even though they will dry and
appear to operate normally, the circuitry could slowly corrode and
pose a safety hazard.
• 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.
• Do not permit a battery out of the phone to come in contact with metal
objects, such as coins, keys or jewelry.
