9Avoid dropping the cell phone. Dropping it, especially on a hard surface, can potenti
ally cause damage to the phone and battery. If you suspect damage to the phone o
r battery, take it to a service center for inspection.
9Never use any charger or battery that is damaged in any way.
9Use the battery only for its intended purpose.
9If you use the phone near the network’s base station, it uses less power; talk and st
andby time are greatly affected by the signal strength on the cellular network and t
he parameters set by the network operator.
9Battery charging time depends on the remaining battery charge and the type of bat
tery and charger used. The battery can be charged and discharged hundreds of tim
es, but it will gradually wear out. When the operation time (talk time and standby ti
me) is noticeably shorter than normal, consider purchasing a new battery.
9If left unused, a fully charged battery will fully discharge itself over time.
9Extreme temperatures will affect the charging capacity of your battery : it may requ
ire cooling or warming first.
9Do not leave the battery in hot or cold places, such as in a car in summer or winter
conditions, as it will reduce the capacity and life of the battery. Always try to keep t
he battery at room temperature. A phone with a hot or cold battery may temporaril
y not work, even when the battery is fully charged. Batteries are particularly affecte
d by temperatures below 32°F.
9Do not place the phone in areas that may get very hot, such as on or near a cookin
g surface, cooking appliance, iron, or radiator.
9Prevent your phone or battery from getting wet. Even though they will dry and app
ear to operate normally, the circuitry could slowly corrode and pose a safety hazard.
9Avoid a battery out of the phone in coming contact with metal objects, such as coin
s, keys or jewelry.
