I've never used the swappolube application, until yesterday, an I must say that it definitely makes a difference in PR1.3.

My battery life now goes down exactly 1% every 7 hrs on standby.

Thats with 2g on and no online apps (pidgin) running. Though I must admit, I did some additional hacking to achieve this.

Before it went down 4% every 4hrs (standby) with out swappolube.
