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 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.

Battery Safety
Standby time will be reduced in the following
conditions:
• When you use the additional features on your
phone such as writing and storing messages,
playing games, connecting to the Internet, and so
on.
• If you are frequently out of the service area.
• 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.
