Snow Leopard: Bad for Battery Life
I've been very quiet on the Snow Leopard front, honestly in the condition it was released it was worth exactly what Apple was charging for it: $30. The bugs and incompatibilities weren't showstoppers, but they were annoying.
Since its release, Snow Leopard has improved tremendously. I'd say we're almost to the point where there's nothing I miss from Leopard. Is it worth the upgrade? Yeah, I'd say so, but do your research beforehand. There are still some incompatibilities that may make you want to wait before jumping. But if you don't use many 3rd party apps or non-Apple hardware, you'll be fine.
The title of this section says it all - Snow Leopard is worse for your Mac's battery life than Leopard. In the majority of cases it's not that big of a deal, take a few results from my 15-inch unibody MacBook Pro review and compare them to the same system under Snow Leopard:
| 15-inch MBP Battery Life | OS X 10.5.7 "Leopard" | OS X 10.6.1 "Snow Leopard" | % Drop |
| Light Web Browsing | 493 minutes | 444 minutes | 9.9% |
You're looking at nearly a 10% reduction in battery life, nothing to be proud of.
That's not the big issue however. The results on the previous page showed something troubling. The MacBook Pro is only able to deliver between 3.7 - 4.4 hours of battery life while browsing web pages with flash ads on them. Looking back at my 15-inch MBP results under Leopard, we see a problem:
| 15-inch MBP Battery Life | OS X 10.5.7 "Leopard" | OS X 10.6.1 "Snow Leopard" | % Drop |
| Flash Web Browsing | 403 minutes | 230 minutes | 42.9% |
I asked Apple on numerous occasions to help me understand what was going wrong, unfortunately I didn't get any response. I tried multiple things from my end. I updated the version of Flash, but that didn't help. It wasn't until I told our own Ryan Smith, one of the people instrumental in getting me to try a Mac years ago, that he gave me a brilliant suggestion: try 32-bit Safari.
Snow Leopard takes another step towards being a completely 64-bit OS, in many ways this step is the most disruptive. Many of SL's applications now ship with 64-bit binaries such as Finder, TextEdit and Safari. You can launch these 64-bit apps in 32-bit mode by selecting their .app icon and running Get Info (Command + I or File -> Get Info).
From there you can check the "Open in 32-bit mode" box. In my case, this gave me 32-bit Safari, which also gave me much better battery life in my heavy web browsing test:
| 13-inch MBP Battery Life | 64-bit Safari | 32-bit Safari | % Improvement |
| Flash Web Browsing | 222 minutes | 323 minutes | 45.5% |
My 3.7 hours of battery life that the 13-inch MacBook Pro gave me jumped up to 5.36 hours. That's an increase of over 45%.
I passed this data along to Apple but haven't gotten anything back from them. I'm guessing the silence on the matter means that it's a known issue and isn't something that's going to be addressed for a little while. Just to be sure, I spent most of last night running OS X 10.6.2 on three different systems to see if it fixed the problem. It didn't.
You'd think that with $1.67 billion in profit last quarter, Apple could afford to hire a couple of engineers to keep its OSes a bit more polished.

Each mac is obsolete, offer lots less functionality, are MUCH slower, have the worst screens, sound, video, processor. have problems or plain incompatibility with most hardware, and 99% of useful software don't run on macs (no, once you run them on virtualized windows, you have all, and each problem of windows, -wich need too buy for extra money)-, and runs too much slower.also, macs are much harder to use, once you try to do something not basic, or find a problem (and macs are crammed with problems), the only way to solve it, is to open a text screen, and hand write LOTS of cryptycal commands.
you go to support, and they start forcing you to sign a contract agreeing to pay to apple U$S 100 or support, EVEN UNDER FIRST DAY GUARANTEE.
Then you find that those "genius bar dudes" are completely clueless...

I just upgraded to the midrange 2.66GHz 15" model. I agree that it is the sweet spot for portability and usability. I had gotten used to the 13" display on my MacBook, but the added screen real estate is nice and the weight increase is minor. The brightness provided by the LED backlight is great. The battery life is incredible, especially when using the 9400M. The build quality so far has been excellent. I can see why Apple hasn't "upgraded" the GPU yet, the 260M seems like little more than a rebranded 9600M. But it works for the few games I play on my computer these days. It does get awfully hot when using the 9600M under load.I considered switching back to a Windows machine, but couldn't find anything that was as thin and light as the MBP, or match the build quality. Those that came close tended to be higher end machines and the cost savings dropped considerably. Having brought my MacBook in to the Apple Store for service, I can say that the service is quite good.
I tried to wait for Arrandale, but couldn't hold out. I may not have the fastest notebook available, but it's fast enough for my needs.

First release of Snow Leopard nicked battery life about 40% off Leopard. Instand huge downgrade. Rounds and rounds of Apple and third party updates now have that down below 20% heading toward 15%.Your 10% testing is solid. It's just still too optimistic for this social media driven world.
The apps I have on all the time are TweetDeck (Adobe Air), Entourage, and Firefox (and by extension Flash). I run 10-15 add'l apps on and off through each day. It's these main three that hit the cpu much harder at times than when on Leopard. I have no time to isolate testing as you have but have watched them in Activity Monitor.
Should also mention I switched to 32 bit Safari months ago. So I'm reporting increased power consumption based on third party apps sitting on Snow Leopard.
Finally, I am also finally coming around to liking Snow Leopard. I've advised dozens of folks to wait and most have. Your real world experience and mine have saved a lot of folks early adoption pain.
Keep up the good work.

"I used IE8 and Windows Media Player 11 in Windows 7 while I used Safari/iTunes in OS X. The results I got were both expected and quite revealing."Absolutely expected, but thanks for redoing the test with IE and WMP anyway.

Ya, very biased test. Run Windows 7 on a Mac to get benchmarks instead of running it on a PC. Good one!GeorgeH - Wednesday, November 11, 2009 - link
My comment was in reference to an earlier article where Windows battery life was measured using Safari+iTunes, nothing more.For the record, there was absolutely nothing biased about this test - a Mac IS a PC, just one with a different BIOS.
sigmatau - Wednesday, November 11, 2009 - link
Um yes it was biased. Running anything Windows on a Mac and taking benchmarks for that and comparing it to native Apple software is biased. Windows runs slower on a Mac. Apple does everything within its power to make MS products look bad. Just look at their iTunes for Windows, complete crap compared to the version that runs on Macs.darwinosx - Tuesday, November 10, 2009 - link
Really good article but I'm surprised be a few of the comments. Mostly about Flash. It's well known that Flash for the Mac sucks. But thats an Adobe issue not an Apple issue. If Flash is acting up for you then uninstall it first using Adobes uninstaller. then reinstall. Don't install over the exiting version. Not all hardware is the same as your generic PC. The motherboard isn't. It is designed by Apple and IBM engineers. Same with the battery and its controller. For generic PC parts Apple has much higher and more stringent quality control standards than Dell or HP etc. So you are much less likely to get a bad part or own that does not perform to spec. If you do have an issue then Apples support is head and shoulders above everyone else. No one else is even close in customer satisfaction. Regarding SSD's it snot like some PC's don't have issues with various makes. I'm using a Crucial 256MB SSD in my 15-inch MBP, 2.8ghz, 512MB 9600GT. Runs very well. I've had just about everything at one time or another during my 20 years in IT and this laptop is way above the pack in every category. A lot of companies these days are offering the option of Macs and every IT Architect I know of has jumped at the chance. We value quality, performance, support and stability as well as the great multi-tasking and efficient use of proc and large amounts of ram that only OS X and Linux/Unix provide. Not like that warmed over version of Windows with all the same old issues. The trackpad is incredibly useful. PC companies are starting to put larger trackpads on their laptops but nothing like what Apple has. As far as prices go you don't have to pay retail. I have a work issued MBP and my own as well. I saved about $400 buying mine over the internet instead of in a store. I had to laugh seeing prices comparison with a Dell 1555. What a cheap hunk of plastic junk. I can't tell you how many work issued Dell's have died on me over the years. About 5 or 6 years ago I had three brand new Dell laptops, top of the line business models, die on me in a single year. 3 brand new laptops croaked in one year. No wonder I have seen so many companies dump Dell and buy HP business laptops. I do like the HP W series laptops and Thinkpads are decent although not as well made with the same material quality as they once were. But I don't see anything keeping me from sticking with macs for a long time to come. The quad cores should be out soon. With 8 GB of ram and quad core you will be able to run multiple VM's as well as OS X making MBP's the most versatile laptop you can buy today.marraco - Sunday, November 15, 2009 - link
...and the sound of those macs are awful. really crap hardware.you play am mp3, and half of the instruments don't sound. those cheap speakers cannot reproduce half the frequencies.

Thats alot of bullshit in this wall of text. Dont they teach you apple fanboys how to structure a post?Especially the QA part on the off-the-shelf PC parts. If their QA was so great, how come they didnt avoid that shitstorm with nvidia IGPs? And thats not the only example.
