Question: have MS Exchange loaded and working perfectly. On the display settings, I picked 20 minutes for screen timeout...however, the screen stays lit up the entire time (no dim). This is probably killing my battery. If I put the screen timeout for 1 minute, I have to input my password every time. I do not have a backlight option in the setting page. Is there any app that will let me keep the 20 minute Exchange Policy before I have to input a password but also dim the screen to save some battery time? Thanks.
