Low Power Browser
I've written about it before. When you're on battery you will notice some browsers are better than others. Google Chrome is definitely not a good choice atm, as it keeps the sound card open, consuming 3 W extra on my system. Switching to e.g. Arora removes all that and is something you should consider when surfing on battery- Opera is pretty good, too.
