Maybe I wasn't clear. If the backlight dims...at all, then rotation stops. No matter if its the built in service or rotationservice, manual, or automatic. What I meant was that its a non issue with me because of rotation service---I only have a couple apps autorotate, and its before the screen dims because I am using them.

You must not let the backlight dim at all. Try this. Turn off all power management settings while its on battery and see what happens.
