Samsung SGH-I257ZKAATT - Manual (Page 18)

Charging the Battery
Your phone is powered by a rechargeable Li-ion battery. The
Travel Charger, which is used to charge the battery, is
included with your phone. Use only Samsung-approved
batteries and chargers.
Note: You must fully charge the battery before using your
phone for the first time. A discharged battery recharges
fully in approximately 4 hours.
Note: Long backlight settings, searching for service, vibrate
mode, web browser use, and other variables may
reduce the battery’s talk and standby times.
Although you can use the phone while the battery is
charging, doing so requires additional charging time.
Using the Travel Charger
To use the Travel Charger:
1. Plug the flat end of the Travel Charger (1) into the
Power/Accessory Interface connector and the other
end (2) into a standard AC wall outlet.
2. When charging is finished, remove the flat end from
the interface connector jack on the phone.
Note: Failure to unplug the wall charger before you remove
the battery, can cause damage to the phone.
