Precautions when using batteries
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
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.
Battery charging time depends on the remaining battery
charge, the type of battery and the 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.
