a few people asked how to get to this when kevindroid first mentioned powersaving app in a thread.i was bored so i decided to find out how to do it.you can find out how to do it here
[How to] [App] Access Power Saver settings in ICS Sense 3.6 - xda-developers
i set it up but didnt really play with it yet but it does work
someone in that thread also made a app for it.i didnt test it but you can find it here

i messed around with it earlier and saw no gain in performance which makes sense since all this is designed to do is save battery life.now if they had a way to change the % that your phone utilizes this hidden setting it would be great for conserving battery.to explain what i mean is lets say you could make your phone starting at 80% only use 1 core you could get much better battery life but sadly i dont see any place where to change that.im sure there are roms to do that anyways.
