Using the Batteries
Your phone is powered by a rechargeable Li-ion
standard battery.
The following batteries are also available (ask your
SAMSUNG dealer for further details):
– Slim battery
– Standard 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 times
are greatly affected by the signal strength on the
cellular network and the parameters set by the
network operator.
• Battery charging times depend 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.

succession, the SIM card cannot be used anymore.

new card.
