The point I'm trying to make is that there are several distinct levels of 
power-usage scenarios (think about it as like what governors are to CPU 
speed), and a 'fixed' powersave scheme (like the don't do this and don't do 
that), while good, is still not optimal. I would like to see a recommended 
power strategy list (like - how to react when you're a CPU heavy program and 
you're backgrounded, or the screen is blanked, or an inactivity timer is 
triggered, etc, etc), basically the things an application can *proactively* 
do to conserve energy, and in that context code examples CAN help standardize 
this .
