OS X 10.8.1 improves battery life

Apple's first update for OS X Mountain Lion is on its way, but the company hasn't elaborated on the changes and fixes in update 10.8.1. However a registered Apple developer with access to the developer seed has found that the update improves the battery life on his MacBook significantly. Before he installed the update, his MacBook showed 4 hours and 5 minutes after a full charge. After the update it shows over 8 hours before the battery runs out.

After the release of Mountain Lion, users began to report big battery drains on their MacBooks. At first Apple didn't respond to questions regarding the matter, but after a week the company started investigating the problem by asking affected users for activity data and system information. Several days ago, a select group of users were offered special builds with presumably a fix for the issue.

The update adresses multiple problems, since Apple has asked developers to test Active Directory, iCal, Microsoft Exchange in Mail, PAC proxies in Safari, SMB, USB, and Wi-Fi. When the update will be released for the public is unknown, but since OS X 10.8 was released a month ago, it's probably sooner than later.

Certainly improved on my computer. My battery is getting on anyway (and I'm getting the Service Battery message), but after an hour I'd be down to about 10-20% on 10.8.0. I've been using it for the same amount of time on 10.8.1 and it's at 60%.

Would you kindly modify the title of the article to read: MacOS 10.8.1 will likely improve battery life? Y'know, in the best spirit 'of where unprofessional journalism looks better'?

PS I just saw a screen shot of Windows Vista's system icons and then another one of Windows 8's. I guess Windows hasn't changed much?

Actually, Windows 8 changed a lot. It's probably the biggest UI overhaul since Vista.

How about Apple actually testing their releases properly BEFORE releasing them. Then people may trust an 10.x.0 release.

You must have no idea how QA works to say something so stupid. This stuff IS tested.

My battery life on my ML 10.8 and Retina Macbook Pro is absolutely fine... in fact it's about the same as it was on Lion on my 2011 MBP. It's clearly not everyone having the issue. I'm sure if it was a solid constant issue that happened everywhere they'd have noticed it. Also ... it's not actually that big a deal. It's not like batteries are draining in 5 minutes. The update will fix it so there ya go.

Considering the limited amount of variety in Apple's hardware... they should've tested it all.
Also they just ignored any complaints regarding issues, this isnt the first time either. They ignore people having issues with their hard/software untill enough people get the issue. Wrong approach in my opinion.

If only you knew
to say something so stupid. This stuff IS tested.
I said tested properly. And why is it stupid, as a consumer to demand this? As mentioned above, Apple had a very limited set of hardware they need to test this against.

It's clearly not everyone having the issue. I'm sure if it was a solid constant issue that happened everywhere they'd have noticed it.
This is the exact point about testing it properly. Now I know you have no idea how QA works.

Nitpicking, but I wish they would bring back the option to show remaining battery time (in hours and minutes) to the status bar. I understand they removed it and made it less visible (in the drop down menu) since it can be information that is lying to the user, but still...! It was usually pretty correct.

Anyway, this is of course big and good news. In the worst cases, I've heard reports approximately halving the battery life, although it seems to depend on circumstances. So this report makes sense. Some have reported improved battery life before this patch, though. *shrug*

So I cut off your leg and then promise I won't cut the other one off tomorrow thats an improvement?

Once this is tested properly and they confirm runtime is the same as it was before the 10.8 or better than surely that is an improvement, for now its just hear say

The article is misleading imho... Especially since this is a BETA release of an update. He claims the additional time is noticed in the estimated run time reported by the Operating System. There is nothing to prevent a bug from being introduced in the way the Operating System calculates the remaining battery run time and, as a result, over estimating. There would be more credibility if he ran a stop watch with and without the update and ascertained any real change in battery run time.

Exactly-- DOUBLE the battery life is achieved through a mere software update? That should at least make you skeptical!

Well, this news makes me consider upgrading to 10.8 after all. (I've been dragging my feet because of the battery drain issue...)
