I've had my phone go into Battery Saver mode a couple of nights this week (playing with the phone during the World Series). One cool thing I noticed when in battery saver is that the Droid Turbo is much, much snappier in speed. It's almost as if it has a Turbo kicking in! (I'll get me coat...)
If you want to try it and see, do:
Settings > Battery > tap the 3-dot menu in the upper right hand corner > Select Battery Saver
