Ok, I don't know what the hell Apple did in Leopard, but my laptop...

    is getting MUCH better battery life. My MBP usually gets (on Tiger at least) 2-3 hrs....I've had this laptop for about a year and it has 96 load cycles on its battery. In Tiger, I used to time how long it took for the battery indicator to drop 1 percent, and it was usually just around a minute. Now, with Leopard, I'm getting 2 minutes and 30 seconds per percentage (brightness at lowest as well). At this rate, it says it'll last 4 hours (screenshot of what all that I'm running below). Also, and this might have something to do with it, my processor temp right now is 112 degrees Farenheit. In TIger, 15 minutes into using this laptop, it was usually at 133 degrees to 148 degrees (just doing normal stuff on it, nothing taxing). This is amazing. I love this OS.

    I also had a feeling that I am getting much better battery time now.

    Well I cant comment much on battery life, because I dont really time it!

    But I do notice that with leopard my CPU usage is a bit higher on average, so I would assume battery life would go down as a result of this, but like I said, I dont have anything to measure it against

    I haven't timed my battery life since getting Leopard but I did notice that my RAM usage DROPPED since upgrading. In Tiger I was getting constant pageouts with 1Gb ram and now in Leopard I am not.

    I've also noticed better battery life lately, and it never occurred to me that it could be because of Leopard. Nicely done Apple, nicely done.

    Now that you mention it, comparing my iStat pro statistics in Leopard to it in Tiger, my RAM usage (by the OS) has dropped dramatically as well. Before, in Tiger, right after starting up with nothing running except startup items, my free ram was always around 1.39 GB. Now, with Leopard, it's always around 1.56 GB. Nice!

    And yesterday, after I started this thread, I sat down to an hour of Family Guy
    and American Dad, and watched my Macbook Pro battery go from 100% to 75% (while I was using it to surf the web intermittently). Friggin 25%. In one hour! That means a 4 hour battery life on a 1 year old machine with 95% battery health! LEOPARD FTW!

    Yes, likewise. I noticed a small but worthwhile improvement in battery life on my (nearly new) MacBook Pro 17" when I upgraded to Leopard from 10.4.10. It still depends very much on what apps I'm running, but overall the improvement is noticeable. Lord knows why..... :p

    On the track
    My Macbook once said over 6 hours with full brightness!!!!

    But I was running no apps... and when I turned one app one if dropped 2 hours. :(

    Oh well, I was excited for a couple of seconds.
