If you're worried about the battery, you should get LXDE. This environment uses the least amount of resources and battery power.
Open terminal and type "sudo apt-get install lxde". When you want to switch to it, logout and select LXDE and login.

I know why the battery drains faster: it's set to the maximum processor frequency. In Gnome, you can add an applet called "cpu frequency scaling monitor" that allows you to change the frequency. I have't used KDE much, but it should be there in the widgets menu. Look for it. Unity is different from KDE; it's Gnome.
