Backlight Intensity and Timeout

You can change settings for the following backlight components:
  • Backlight Intensity—The brightness of the screen during phone activity and inactivity.
  • Backlight Timeout—The number of seconds the phone is inactive before the backlight dims to its Backlight Idle intensity. The backlight timeout period begins after your last activity, such as an incoming call.
Backlight Intensity includes the following settings you can choose from:
  • Backlight On—The brightness of the screen when there is activity.
  • Backlight Idle—The brightness of the screen when there is no activity.
  • Maximum Intensity—The brightness scale that applies to both Backlight On and Backlight Idle intensities.

Set the Backlight Intensity

You can change the Backlight On intensity and the Backlight Idle intensity separately. You can also choose a high, medium, or low intensity, or turn off the backlight entirely. When you change the Maximum Intensity, you modify the entire backlight intensity scale. For example, if you decrease the Maximum Intensity, the low, medium, and high levels for both Backlight On and Backlight Idle intensities decrease.

Procedure

  1. Navigate to Settings > Basic.
  2. Select Backlight Intensity > Backlight On Intensity.
  3. Select the intensity you want, and select Back.
  4. From the Backlight Intensity screen, select Backlight Idle Intensity.
  5. Select the intensity you want, and select Back.
  6. From the Backlight Intensity screen, select Maximum Intensity.
  7. Select Up or Down, or drag your finger along the slider to increase or decrease the maximum intensity.

Set the Backlight Timeout

The backlight automatically turns on with any phone activity. By setting the Backlight Timeout, you can determine how long the phone should be idle before the backlight dims to its Backlight Idle intensity. By default, the backlight dims after the phone is idle for 40 seconds.
