Battery issues seem to be largely software related. I haven't been paying it much mind since the bulk of my usage is at work or home (where I can charge it). I got rid of AP news widget which originally gave me performance issues as well as battery. Also got rid of the facebook widget after a while (since its kind of useless). I do use pidgin a lot or the telepathy-haze plug for AIM/gtalk, web browsing, email, transmission.

I have moments when I go "**** this battery is so easy to run down!" considering how much stuff you can run on the phone. I also have been imcreasingly saying "**** how do I have so much battery life still!

The browser seems to have some CPU issues. Having to use full versions of websites is a blessing and a curse. Flash is definitely a battery killer but sometimes I'm not sure why the browser is pegging the CPU so hard. I think email (IMAP at least) is bad also because of how poorly the client handles IMAP mailboxes and HTML emails.

BTW this is now like my 4th day with no computer! Hehe, getting by pretty well with just my N900.
