Updating Power Saving Settings
Your phone is set up with a power-saving mode that turns off the touch screen
to conserve energy. Your phone enters power-saving mode after it has been
idle for a certain period of time and its camera doesn’t detect motion. Your
phone will not enter power-saving mode if it detects motion (for example, if
you are near the phone), even if the phone has been idle for the period of time
you specified.
You can configure the period of time that the phone is idle (“idle timeout”)
before the touch screen turns off (if the camera does not detect motion). You
can configure different idle timeouts for office hours and off hours (evenings
and weekends).
