OS X 10.8.1 beta said to substantially improve battery life

post #1 of 39
Thread Starter 
Apple's pre-release build of OS X 10.8.1 Mountain Lion has improved MacBook battery life by as much as four hours, according to one developer.

The substantial improvements were discovered by an unnamed developer who spoke with Softpedia after installing OS X 10.8.1. Previously, the developer's MacBook was reportedly showing a battery life of 4 hours and 5 minutes after a full charge, but installing the beta software increased the advertised battery life to over 8 hours.

The details suggest Apple is working to fix battery life issues that some users have reported since the release of Mountain Lion on the Mac App Store in July. AppleInsider first highlighted earlier this month a number of MacBook Pro and MacBook Air owners who complained of battery performance issues after installing Mountain Lion.

Those complaints were later validated by a series of tests conducted by ArsTechnica. Their unscientific data showed that Apple's new operating system drains batteries significantly faster than its predecessor, OS X 10.7 Lion.

While Apple has not publicly commented on any battery issues with Mountain Lion, a number of users who have posted on Apple's official community forum have said that company representatives reached out to them and obtained system information in an attempt to fix the issue.

Mountain Lion


Only certain MacBook models have been reported by users to experience the battery drain issue introduced with the launch of Mountain Lion. Some others have said that their battery life actually increased since updating to OS X 10.8.

The first pre-release beta of OS X 10.8.1 was supplied to Apple's developer community earlier this month. Documentation accompanying Build 12B13 revealed it aims to correct a display noise issue when using Thunderbolt, but made no mention of battery life.

I don't understand how AI does not enforce their editors to actually look over material before it goes live. There are plain-text HTML links in this article and typos. I know my university teaches me to proof read...

Agreed. They have the fewest mistakes out of all the blogs I read though...iPhoneinCanada is the worst for proof reading though!

I value my MacBook Air's ridiculously long battery life in Snow Leopard, and I don't want to upgrade until this issue is positively ironed out. I am hopeful that the .1 release of ML will put the issue to rest for MBA users!

I do hope that 10.8.1 does something to address the creakingly slow performance of Safari's Javascript engine.

 

On my connection, it takes about 30 seconds to load a single page of Appleinsider in Safari since the Mountain Lion update. If I use Firefox (which I don't really like) it loads in the blink of an eye. If I turn Javascript off on Safari, most pages then load instantly, but of course I lose functionality. It's driving me nuts.

 

EDIT: I would also point out that I've compared an upgrade to a fresh formatted disk install of ML on another of my Macs and the issues are the same, so it's not something old hanging around and getting in the way.

Try reinstalling; that's not indicative of any Safari I've seen since about DP2.

interesting. one developer. i know a developer -- another developer, but one developer, nonetheless - who says his battery life has decreased by 1.5 hours. so please give the opinion of the one developer i know the same amount of weight as you would give the opinion of the one developer in this "article" .

oh, and ffs, spend some of the money you earn from ad impressions on a proof-reader.

I did mention that I've done that on a different Mac - wiped the hard drive and started again from scratch and the same issue occurs. Maybe you didn't pick up my edit in time.

 

Is there any way to uninstall and reinstall Safari?

To be fair, the AI website isn't really optimised at all. It's slow and has some odd functions, whatever browser you're using. I know this isn't AI's fault as they have bills to pay.

I would quite understand that, except that pre-Mountain Lion I never had a smidgeon of a problem loading pages. It's fair to say that what with the Javascript problem and Safari also occasionally completely closing itself at random points in time, I'm getting a bit frustrated! Apple is better than this!

Battery life is critical, I'll grant you.

Have you disabled all your extensions?   I've found that some extensions are not compatible with Safari 6.  Mine loads 'okay' with just AdBlockBeta, more like 5-10 secs for AI, but mine is a late 2008 unibody MacBook.  YMMV.

 

I've also found pathologic stuff corrected when I deleted the safari caches in my ~/Library   (I'm on my work XP machine now, otherwise I'd be more specific).  However this was 6.0 on Lion, not ML.  (my home automation system dictates that my mini doesn't upgrade until 10.8.1... gotta keep the lights on).

Something else is going on.  I've upgraded both my mid-2011 MBA and late-2009 iMac to 10.8 and Safari was definitely more snappier.  Then after a week, I decided to clean-install 10.8 (simply because I could) so that there are no remnants of prior programs or plugins.  Both machines run very well, including Safari.

You might want to see if there are Safari plugins that are causing problems or other programs sucking-up CPUs.  I had a minor issue with a plugin when I upgraded.  I always like to do a clean-install of OSX whenever a new release comes out simply because I like having my system fresh-from-factory clean.  Some Adobe plug-ins really effed-up a couple things.  That's only though after I've put the release through the ringer for a week or two before I update my main system.  Fortunately, all my data is in Dropbox, or time machine so I don't worry too much about losing something.  I also try getting my apps through the Mac App Store so that I always have it on tap when it's time to re-install.

Just my 2-cents.

Hope they also patch defective context menu, disappearing desktop icons, involuntary log outs, beach ball of death, buggy install, and then Apple should rename it 10.8.0! :/

post #17 of 39

I'm one of the people Apple contacted and while I was on the phone with the Apple Tech, my battery went from 98% to 75%.   Even he was surprised.  (MBP, late 2008)

 

I also have the problem where something is causing the machine to freeze-up and lose WiFi connectivity.   Never happened before Mountain Lion.   I used to reboot about twice a year (aside from when I shut the machine down to take it somewhere, which wasn't actually that often.)  Now I have to reboot every 2-3 days.   It was every day, but I shut down some programs, like iTunes, which seems to help the situation.

 

I had never installed Lion, but I do find that Safari is much faster than before.  

 

In the past, I had always waited for the .1 release to upgrade.  Don't know why I didn't wait this time - now I'm really sorry.

 

Hope they get this all fixed soon.

 

I have to admit I was pretty impressed when the Apple Tech called me.    Not that he was able to fix anything, but I did feel better knowing that Apple was at least taking the battery life situation seriously.  I hope they're taking the freezing complaints just as seriously.

what does the timing of your reboots have to do with your battery life? does rebooting magically charge the battery?

On 8/16/12 - -  Apple Genius Bar says:  

 

“We have never heard about this issue and we don’t read the online stuff since they are only complaints.” 

 

Seriously?  

 

I was told that to go back to Lion I'd lose all my data.  Thanks for the love, Ms. Genius......

 

The approx. 40% cut in battery life is a failed upgrade.   OS X 10.8.1 - - can't be released soon enough.

There's no reason why you'd lose your data to go back to Lion.

Pay $100 to be a developer. Though I'd personally rather people not waste their time with prerelease software when they don't even know how to get it, much less use it.

Beyond that running beta software can be pure agony! It is far better to wait for the upgrade.


As for all the whinnying on here about battery life, I have this suggestion for people, focus on the good things in Mountain Lion. Every software update you ever install will have problems even if you as the user don't see them. It isn't like the machine has become totally unusable. If you wait for perfect software you will never see an upgrade or new program on your machine.
post #25 of 39

Surely the machine isn't unstable but clearly the battery life issue out weighed the "good things" for the end user that is involved in this upgrade.  

 

Just saying............

One shouldn't have to go through this kind of song-and-dance for a browser software, for heavens' sake! Especially when it worked fine in previous iterations.

Dag, yo. (Did I use that right? Can that be used right?) I guess the next step is to look for common hardware to see if combinations thereof (plus software) might be causing it.

I know this is far from the main story, but on the topic of Safari 6.0, it was irritating that clicking on links would open the new page in the same window while simultaneously graying out the 'back' button (the only way to get back was go into History, and resize the page again!).

 

Until I discovered that one had to go into Preferences --> Tabs and set "Open Pages in Tabs Instead of Windows" to "Never". It is now fixed.

 

(i) I don't ever recall having to go through this kind of nonsense with Safari before; (ii) I am not even sure that I still understand the language usage and logic involved in getting it to do what I wanted; (iii) I hope this (and a few other minor irritants, like offering to remember passwords, wtf!?) isn't the creeping microsoftification of Apple's software.....

I have never used TimeMachine and although I have a free Dropbox I have never used that either for anything other than to test it out. I had iDsk which was convenient for sending myself stuff I wanted to work on at home, but all of my backups are on external HD, and also copied to my remote datacenter or on various other media. I have 3-4 levels of redundancy in my backups.

 

I have never done a clean install because I don't want to go through the application serial number registration activation routine and I have lots of that type of professional applications. Other than the app store which already know your serial number it sounds like a hellish undertaking. I can't imagine doing a clean install when I have a terabyte of data on my internal drives, which of course is the master copy. Everything else is just in case of emergencies. Apple has always done a really good job of upgrading the OS in my opinion.

One thing about Apple, is that they are pretty good about getting the major bugs ironed out quickly.  It just takes a little time identifying the major bugs, working on the code, testing them so they can release.  It happens every major release of an OS and it's nothing to be worried about.

My opinion (just worth an opinion) is that it's better to wait for the update to the upgrade. Also true for hardware :D

I agree. I don't like L/ML, I'm a SL guy I guess, but years of OS experiences ranging from Microsoft to OpenBSD taught me that OS upgrades can be hell.

 

Just a few weeks ago, a standard-vanilla-normal-not-modified Ubuntu completely failed an update, after coming out of an internet-less bunker it stayed in for two years. It was three versions late, but still, it's pretty irritating to end up reinstalling from scratch a major OS because nobody thought of proofing the system for those people who rarely update.

 

Apple's no Debian, but they're among the best in upgrade management. lol.gif Also, now that they've finally mastered repositories with their version of Apt-get (the "APT"-store), it's simple lol.gif

Any idea when it'll be released? I'm getting a Retina Macbook (hopefully by next week) and I'm worrying about the battery life and screen issues.

I recently started using Google Chrome for my iPhone, iPad and Mac. I'm really happy with it. It's fast and on the iPhone & iPad it has unlimited Tabs which is unprecidented. Not full screen yet. But the unlimited Tabs is a feature that trumps full screen for me. Perhaps Chrome for Mac would help you forget Safari's new shortcomings. It has for me. And you can make Chrome your Mac's default browser in the default browser setting in pane 1 of Safari. 😃

You don't need to pay to be a developer.  Just register at appleseed.apple.com.   Have been doing this since they started testing Lion.
