The point with battery consumption is not about running vs. standby.
The issue is that while users expect that running apt-get will drain the
battery, they expect that once apt-get is done, the only battery-hungry
processes are ones they start themselves.  Laptop users typically avoid
running apt-get without mains power plugged in.  If I do an 'apt-get
upgrade' then afterwards my CPU will be churning away compiling addon
packages, so I can't just unplug.
