OS X 10.8.2 Restores Notebook Battery Life to OS X Lion Levels

Still terrible 3d performance (AMD HD2600 - iMac early 2008) compared to 10.6.8 (-10% in Cinebech). No love for the older cards?

I really miss the option to choose the driver that performs better like other OSs, and they obviously made the bad choice for my needs - ATI drivers v.8 really suck... :mad:

Apple are you listening. Far too many products - hardware and software are being released that clearly need months more development testing. You mojo will be lost sooner rather than later if this continues.

I wonder what the iPhone 5 has wrong with it......

Fair enough, but I think Apple might argue that they need volumes of data from real-world use to really sniff out and resolve these types of issues. Looping an HD video to see how long a battery will last is vastly different than having thousands of data points to see where the bottlenecks are.

Not defending or apologizing for Apple. I just think there is a little more to the story.
 
I haven't had any battery life issues with Lion but if 10.8.2 is better then that's even better for me. :)

Real-world data could be gathered if they tried to do the same that MS does: open betas. It works and Windows 8 is almost bug-free and runs in thousands of PC configurations. :)

Hi guys; I performed the tests for The Mac Observer. As I explained in the article, we were also confused as to why the HDD was getting better battery life than the SSD. We looked into it and discovered that our hard drive, a Western Digital Scorpio Blue, is extremely power efficient, using .59 watts at idle and 1.4 watts while active.

This is very low for a mechanical hard drive and our high performance Vertex SSD used more power: 1.3 watts idle, 2.5 watts active.

Some low speed, energy efficient HDDs have closed the gap in power consumption with SSDs, but YMMV.

Thanks Tanousjm. It's good to hear someone explain this based on facts rather than speculation. I was curious about it too -- but had chalked it up to perhaps the HDD being put to sleep due to inactivity or something.
 
glad if thats fixed but for me it would be more important to fix the wifi disconnects
 
i have been using 10.8.2 for about a week now and i can confirm that my battery life is better. i just wish all the flash p0rn sites didnt kill my battery. :D

Great news - sounds like they've achieved software perfection! I'm looking forward to never having to update my Windows 8 machine with bug fixes or optimization updates!

"Never" is just too bold... But having to wait three months for basic functionality is hardly acceptable. ;)
 
Suddenly it becomes very clear to me, why the "remaining battery time" wasn't shown anymore in the menu bar as it was possible in 10.6.8 ... - What a cheap trick! - Does 10.8.2 also finally give us back the remaining battery time in hh:mm in the menubar?

you just have to click on the battery to see that time remaining no tricks
 
Is this occurring for non-iCloud users? My battery life dropped and it is most definitely the fault of the ubd process, which is the "Documents & Data" portion of iCloud syncing. Turn it off, get your battery life back.
 
10.8.2 still takes longer to shutdown than 10.8.1. It took less than 6 seconds for it shutoff on .1. Now it takes about 15-20 seconds.
 
Looks good for the people with issues. I'm getting 7-8 hours under 10.8.1 (Early 2011 15" MBP) so I'm not expecting 10.8.2 to help much in my case, but more is good :)

Windows 7 was open beta too. It's mainly pretty stable, but there are quite a few horrible bugs that have been around since Windows Vista which have caused computers in our project to have to be re-imaged on multiple occasions.

And "basic functionality" is all you get with Windows, so perfect! I think we can now all agree that Windows is empirically better than OSX

So, can you imagine what could go wrong with closed betas?
I for instance can't turn off my rMBP display while on a secondary monitor without many complicated tricks. Also, there's a bug with NTFS drivers that have messed up my Macs for a long time.
It is all about solving the most common bugs before release, not all. Thus having more time to fix the least common ones.

Mr. Fanboy, we're trying to comment on important things, not childish conclusions. Stop trolling.
