Snow Leopard changed the brightness range of MBP 13" ?

Same here. My battery life is worse since the brightness is so high. Hopefully Apple fixes this dumb issue. They have the Hard Drive problem already, so maybe this'll come in Performance Update 2.
I'm sure a fix will come, the only question is when.
The other great thing about having so much battery life, is that it reduces cycle usage. I am on AC most of the time, so after a couple of months I am still at only 13 cycles of use. I typically use battery power for only a couple of hours at a stretch (but appreciate the longer battery life when needed.)
The new batteries already offer greater lifetime (1000 cycles IIRC), but I guess the real impact is 1000 x battery life of 1 charge.

From another website that considers itself to be an "insider" for apple users mentions:
"As was the case with last week's beta, documentation accompanying build 10C535 reportedly lists no known issues. And while Apple has temporarily ceased its practice of providing a running list of bug fixes that will come baked into the impending release, it did identify 148 components that have seen tweaks.
Among those components are AppleBacklight, Battery Menu, Dictionary, Expose, FileSync, Family Controls, Fonts, Front Row, HFS, Inkwell, iPhoto, MobileMe, OpenCL, Parental Controls, QuickTime, Screen Sharing, Spell Checker, Spotlight, Time Machine, and USB.
In bare bones Delta form, Mac OS X 10.6.2 currently weighs in at roughly 480MB. It's expected for release sometime next month. "
Notice that the first thing mentioned is "AppleBacklight". Is that what we want fixed/addressed? I include myself because I got a macbook pro last night with the 9cc2 screen. It came with that blue tint but theres a color profile in the forums that works beautifuly to correct this. Now I love the way it looks (and its dead pixel free), but yes its much brighter than it should be at one click backlight level. I put it side by side with my unibody aluminum macbook (2008) and it seems like theres a 6(maybe 7) tick difference. Meaning the macbook pro at 1 tick equals the macbook at around 6. The macbook pro reaches a slightly higher brightness when both are maxed out though. This could just be an illusion due to an improved panel. Viewing angles is no contest, macbook pro wins hands down.
I dont think im going to be exchanging this computer at the moment. This seems like its more a software issue than anything else. Please correct me if I'm wrong

Thanks for that info redcrow. It should be a software problem, not hardware- assuming you are on Snow Leopard.
That news about the update gives me hope. I was considering downgrading to Leopard for now, I also get more beachballs than before (especially Safari.) I also did an upgrade rather than clean install, next time I am going to do a clean install.

Just thought id mention another tidbit ive read online. It seems like snow leopard is missing a very important file needed for the 9CC2 panel to function correctly (been verified by several members). It is instead defaulting to something else (which would explain the blue tint too, and lack of lcd profile). I read this over at apple.com forums. I will look again later today and post the exact discussion.
Im back with some info. Thanks to the thread and all the users posting at apple.com btw

Below is the snippet thats most important in my opinion:
"Regarding the color profile/blue tint issue, here's what I've figured out is the problem with Snow Leopard, and the LCD panel model 9cc2 that I have.
Knowing from the ColorSync profile on my MacBook Pro 13" that the display make is 610, and the model is 9cc2, I went hunting in the System Folder.
If you go into the folders: "System", "Displays", "Overrides", "DisplayVendorID-610", and scroll down through the list. You'll notice that a DisplayProductID is MISSING for 9cc2!
Apparently Apple left 9cc2 out of displays in Snow Leopard."

I wonder if it's possible to copy whatever file(s) from Leopard for our display to a Snow Leopard installation.
EDIT- Some people in the Apple thread have tried it, and some have apparently fixed the blue tint issue. But no word on the screen brightness (and battery life.)

So I just re-installed Snow Leopard from scratch, and restored my data from my Time Machine backup.
I'm not sure if the display brightness levels have changed (I'm in office light so it's hard to tell.) But on lowest brightness and a charged battery, Finder is reporting 7 hours of battery life left.
EDIT- Upon further usage, my battery life after wipe and re-install with Snow Leopard has not changed, it's still less than with Leopard.

Just a heads up, the 10.6.2 update has solved this problem. Thank God!!
Hows everyones battery life now? Has it improved with the update? Battery life seems to be better for me now since the screen dimming is working now. I also noticed that my temps are a little cooler now, back to where it was on Leopard. Overall I'm really happy with this new update.

yep, we can now enjoy much better battery life Ive been hitting a tiny bit over 6 hours with heavy browsing on safari with click to flash (website activity every 30 seconds at least), at least a dozen flash videos (no more than 5 minutes each), and constantly streaming itunes. Backlight is at 7 ticks, keyboard light no more than 5 ticks.
PS- has anybody else noticed that itunes takes more resources now with 10.6.2 than before? Activity monitor used to show no more than 6 %cpu for it, now it doesnt go under %9.6 and is almost always at around %13-15 with the same music. Im not complaining, but would like to know if anybody else has noticed this.
