Health and safety information
• If you are out of the service area for a long period
of time.
• If you use the phone out of the network's local
service area.
• If you use the talk mode repeatedly
The battery can be charged and discharged
hundreds of times, but it will eventually wear out.
When the operation time for both talk mode and
standby mode is reduced by about half, it is time to
buy a new battery.
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
