Funily enough I have an X230T too and I'd like to switch over to that. I cant get my battery life on my X230T to match my X220 at all. Any tips for this?

I can't wait to have a note-taking pen tablet laptop thing, battery life is just a big factor for me. I'm a college student and need to be able to run my laptop from 8AM to 12PM. X220 works great for that. X230T is not there yet for me.
