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.
