Using the Battery
Note: This phone comes packaged with a partially charged rechargeable
standard Li-Ion battery and Wall/USB Charger. 
You must fully charge the battery before using your phone for the first 
time. A fully discharged battery requires up to 4 hours of charge time.
Important!: Although the phone can be used while the battery is charging,
the battery must be fully charged before first use, otherwise you 
could damage the battery.
Battery Indicator
The battery indicator in the upper-right corner of the display 
indicates battery power level. Four bars 
indicate a full
charge, while an empty icon
indicates an almost empty
battery. Two to three minutes before the battery becomes too low 
to operate, a blinking empty battery icon appears and a tone 
sounds. If you continue to operate the phone without charging, it 
shuts down.
Using a Non-Supported Battery
Samsung handsets do not support the use of a non-supported 
battery.
When using a non-supported battery you will hear a series of 
beeps and you will see a warning message that indicates “NON 
SUPPORTED BATTERY. SEE USER MANUAL” If you receive this 
warning, battery charging has been disabled.
Samsung charging accessories (i.e. wall charger, and cigarette 
lighter adapter) will only charge a Samsung approved battery. 
To continue use of your handset press
.
Note: When using a non-supported battery the handset can only be used for
the duration of the life of the battery and cannot be recharged.
Important!: Using a non-supported battery may cause damage to your
phone. Use a Samsung supported battery only.
