I am not getting that option. When I try to increase the time, it is only showing 10 seconds because of (Exchange ActiveSync Policy). How do I get around that?
Change Screen Time Out on HTC One can make battery last longer. You can set to turn off the display after being idle from 15 seconds to 10 minutes or never. To change the setting do as follows:
1. Open “Settings” app and go to “Display, gestures & buttons”
2. Tap “Sleep”
3. Choose, Auto Sleep, Never turn off, or from 15 seconds to 10 minutes
