    Battery life durations specified on our products are tested in our labs under multiple different conditions and the talk and standby times are a realistic average maximum dependent on customer usage variables. Some variables that may affect battery life are:

    • Backlight settings set to always on, or a long amount of time
    • Ring tone settings set to higher volume settings
    • Vibrate settings turned on
    • Using Internet Services including Text Messaging
    • Making and/or Receiving calls in, or simply standing by in an analog service area
    • If you tend to be in a "weak" coverage area where your signal strength meter shows only 1 to 2 bars
    • Using non-SAMSUNG charging accessories can cause battery life and other issues, as well as void the manufacture's limited warranty.
