Amazing...
So after several calibrations and ~45 days of use, I was starting to get a little disappointed in the 10 hr battery claim for the 2010 MBP 13" I picked up. Under no circumstances was I ever able to get anything over 8 hours. Now, this was a slight improvement over the 6.5 hours I was consistently getting on my '09, but still....
So my conclusion is this: since the 2010 has a physically larger battery, albeit not VERY much larger, there is a large amount of battery efficiencies to be gained from whatever changes are in the 10.6.3 load designed specifically for the 2010 MBP.
Same goes with the inertial scrolling.
So, if there would be a way to identify what specific packages are installed on the 2010 vs the 2009, the folks with last years model "should" be able to enable inertial scrolling, PLUS get at least some of the increased battery life claims.
Oh, since I was also digging around, I found a couple of other "problems" - or rather things hogging my CPU that I wasn't completely aware of. SMSDaemon - which I found out was a piece of the Syphone software that I had installed and had not used in some time - was firing up every so often in the background and eating into CPU. At times, it would hit 30% over a couple of seconds. Probably not good for the battery or overall performance. It was also logging information in console.
Secondly, iStat menus - I loved it - now I've uninstalled it. It was consistently using 1-3% of the CPU. While I know this isn't "a lot" - since I'm on my battery crusade - I decided to remove it.
As I write this, I'm @ 95% - 9:12 remaining - something I've NEVER seen on this 2010.
