On the power saving side, I utilize a handy outlet switch from GE (though the Belkin one appears to be highly functional as well)
This allows me to never have to unplug the charger or reach down to the floor. Although the power draw is small - every little bit helps over time.
Just make sure to flip the switch to the on position prior to getting into bed each night. Note: These days, I like to use white power cables, easier to see in the dark.
