OS X Mountain Lion may be degrading battery life, test shows

post #1 of 84
Thread Starter 
In response to an Apple Support Communities forum thread, a report on Tuesday offers anecdotal evidence that the new OS X 10.8 Mountain Lion may be causing battery life issues for some MacBook users.

According to a test conducted by Ars Technica, there may be evidence that Apple's new operating system is draining batteries significantly faster than the previous OS X Lion, as the publication's test unit lost some 38 percent of runtime after having installed Mountain Lion.

In a series of unscientific tests, a MacBook Pro with Retina display was run on battery power both with and without Mountain Lion installed. Ars was able to hit just over eight hours of runtime with Lion and the integrated Intel HD4000 GPU, meaning the computer wasn't leveraging the discrete and power-hungry NVIDIA GeForce GT 650M. With Mountain Lion installed and using the same settings, however, runtime dipped to around five hours.

The test was conducted a number of times, each using the same applications under what was described as a "daily workload." Being used actively were Safari, Chrome, Twitter, iChat, TextEdit, Photoshop, Mail and Outlook, among others while Dropbox and gfxCardStatus ran in the background. As far as systems settings, Wi-Fi was activated while Bluetooth was turned off and screen brightness was set to half-strength.

Mountain Lion's Activity Monitor was used to check CPU usage and, while there were occasional spikes when reading or writing files, loading web pages or other user-initiated operations, the processor was usually below five percent capacity. This is contrary to one account from an Apple Communities forum member who noted a heightened CPU temperature when the computer was idle.

Mountain Lion


A 49-page Apple Support Communities thread first started on July 25, the day Mountain Lion was released, chronicles a number of battery issue complaints from users who recently installed Apple's new OS.

A few forum members suggested the problem lies with one of Mountain Lion's new features like Power Nap, while others have found limited success with resetting their machine's system management controller, but a legitimate fix has yet to be discovered.

Interestingly, only certain machines are affected by the purported battery drain issue and some users are even reporting their battery life increased after installing the new operating system.

Apple has yet to release an official statement, but a number of forum members affected by the issue claim Apple representatives reached out to obtain system information in an attempt to remedy the problem.

Welcome to Microsoft software development.  Release now, fix bugs later.

Looks like the MobileMe team was allowed back into the rest of Apple!

 

Snow Leopard is giving me 8-10 hours productivity on a 2010 MacBook Air. Mountain Lion's not going anywhere near the SSD until 10.8.6, at least. Point-six is usually when I upgrade. The extreme guinea pigs will probably be on 10.10.0 by then.

I haven't noticed any battery issues with ML since the initial beta but I wouldn't doubt there are such issues. This is par for the course with a major OS update.

I'm always a late-comer to OS releases myself. I upgraded to Leopard when SL was released and upgraded to SL just about 3/4's of the way into the OS's lifecycle. I usually do it about half-way in to give it time to work out the kinks. ML looks like another great OS X release and I'll probably upgrade later on but for now I'm happy with Lion.

 

I suspect this will be blown out of proportion like most Apple "scandals" do.

OMG! Yes! I've been trying to get a few things straight, but multi monitor support just went "out the window" so to speak.

I filed a bug report with apple. Actually, three of them. Hopefully they fix this.

I read so many comments here on how mountain lion would be a fix on lion, just like snow leopard was one to leopard. Don't blame me folks. I took this from your comments.


....it's not a fix. Period.

I also wish the people posting on Apple Support Communities would just submit a bug report.

However, I haven't noticed any battery problems with my new retina Mac... Just saying.

(disclaimer: I'm too young for Leopard, so I actually LISTENED to your remarks.)

I've been having freezing issues like that too (system frozen, mouse still moves). I've had two of those instances so far with Mountain Lion -- never had any freezing issues with Lion. I've also noticed that SystemUIServer has crashed on me at least 3 times since installing Mountain Lion. Or at least I think that it's crashing. The Menu bar shows a spinning wheel and won't respond when I hover the mouse over it -- I go to Activity Monitor to find SystemUIServer taking up about 54% CPU. I hit Force Quit, the process restarts itself, then all is well. 

 

Again, an annoying problem I never had with Lion.

My 2009 i7 iMac had its first system freeze ever.  I'm about 3-days into ML.  However, mine is the reverse.  The mouse and keyboard stopped responding, but it seemed the machine itself kept running.  I considered that the BT keyboard and mouse may have lost the connection, but it still remained unresponsive after I plugged in my original iMac wired keyboard.

I ended up doing a clean re-install of ML instead of upgrading from Lion.  I like clean systems.  Other than that, been a solid update.  I am looking forward to 10.8.1 to address these and other potential issues that I'm reading with other people.

I upgraded my 2011 MBA the day after the ML release.  Clean-install too.  Been working just fine with the exception of the battery life taking a hit.  Fortunately, I leave it plugged in the entire time at work so I'm not impacted by it really.

Let's get these fixes in Apple.

This is a new one on ML. Wait until you can't get out of your screen saver... It will come. Just be patient.

When people, you included make these kind of claims about what you are and not going to do, do you really think it matters to people?

Some times I wonder if you guys collectively understand what you are doing? In my TEENS, we used to have to do a clean install of Winblows... So if you are doing this I should never hear you posting a bad remark about Micro-soft.

Also, I'm betting you didn't do a clean ML install. I'll wager you did a Snow Leopard, to Lion, to Mountain Lion install... Just a guess. Wait until you actually do a REAL Lion install. The results can be shocking!!!

I had the same issue, and luckily just re-booting was fine. It said Apple would get a report, which is fine.

However I can't stress the how interesting is it to see 'long time users' post hatred thoughts about competitors and then explain how they needed to do the same thing with their machine.


So collectively here windows gets trashed, and it is horrible, but then I read posts (and experience), about the same (or worse) problems with OSX.

Interestingly, multi monitor support has been on the forbidden operating system for a long, long time.

Just my 2 cents.

Enough of your sensationalism and your condescension. Nobody cares when you plan to update or the fact that you're running an OS 2 generations old. It doesn't make you any more intelligent or informed, as you seem to believe. Extreme guinea pigs'? I updated to ML instantly. You know why? Because I read a dozen reviews before then, all of which stated that it was a rock solid release. I didn't want to wait several months to take advantage of features such as much better iCloud syncing, airplay from my mac, notification center, messages, powernap, notes/reminder syncing, dictation, much better safari, dozens of small tweaks + performance improvements, etc. I haven't experienced a SINGLE issue with the upgrade, my battery life actually seems better, performance is better, and everything has been rock solid. This isn't some experimental beta software, its an OS that has been made public to tens of millions of people from a company that has alot to lose if there's serious problems with it. Are there some people who might experience issues? Sure. There's so many code changes in a new OS that its impossible for everyone to have a completely smooth experience. But all indications show that this is one of the best (if not the best) .0 release from Apple yet, and from my own personal experience it certainly is. Every piece of software I've tried works, the new features are great as I actually use many day to day, and there's been absolutely no downsides. The OS is tighter in every way. I'm sure millions of others have the same experience.

 

You want to wait, thats fine, more power to you. But don't insult those who already upgraded as if you have more insight than they do. It's great that SL is fine for you, but I could never ever go back, after getting used to how things work in ML. I'm not going to call you an idiot for not updating, and you shouldnt call those who have chosen to do so idiots either. The MobileMe comment is also absurd.

I'm really starting to like your objectivity. Good call! As we say in Boston, "Cool Beans!"

Actually, I'm very interested. You haven't had a "single" problem? Do you do multi-monitor work?

I'm also being trivial here, (very, very trivial) but did you notice more screen savers yet fewer screen saver options?

...and before some one rides my case about just screen savers. There's more than that.

That was my experience with Lion on a macbook '09 and it didn't improve much even after a clean install, etc.  I upgraded the RAM, tried all the usual forum advice, but in the end I just accepted the new OS requires more power for my basic usage.  Having nothing to lose, I've since upgraded to Mountain Lion and I like the OS even more, but I still find the battery life is my only issue.

While I do fundamentally understand "how" battery life could be effected by a software upgrade, I do find it extremely implausible that it would actually happen. Other than Apps/Programs running constantly it just doesn't make sense.

This is, I think, a user case scenario.

I don't mean to come off as dissmissive, but I literally haven't studied in detail how software and batteries work.

Trust me, some users (I hate saying users) don't even know what's actually running on their device.

Also, after having to do a "clean install", you will be further stricken from the record on opposing operating systems.

I have a great memory. One that hurts me more than helps me. It's photographic.

Upgraded my 2009 iMac from Lion (Lion install was done as a clean install shortly after release).  No issues, runs nice and quick only been rebooted once since upgrade after I changed the location of my iTunes library.

 

No lockups/freezes or otherwise.

 

Macbook Pro late 2011 (SSD - HDD in Optibay) Clean install with Mountain lion.  No lockups freezes or otherwise.  battery life clocks in at 6-6.5 hours per day with 60% screen brightness.

 

What I run:

 

iMac -Usenet downloads, iTunes (serves media to 3x Apple TVs), Photoshop, Dreamweaver, Outlook 2011, Mail, Safari, World of Warcraft, Parallels 7

 

Macbook - Outlook 2011, Photoshop CS5, Mail, Safari, Messages, iWork, Word 2011, Excel 2011, Parallels 7

 

I get exactly the same usage on battery as I was getting under Lion on my Macbook which is fine as it lasts me a full work day.  If I need to eek out more battery life I reduce the brightness and use my iPad for email instead of outlook, I also disable dropbox, skydrive and any other little programs running in the background, this normally gets me around 8-9hrs uptime.  If I use Parallels on the Macbook it cuts battery life down by half straight away.

It is a well-established fact that OS X spends a great deal of energy indexing the hard drive after installing the OS. Any test that doesn't acknowledge that fact or confirm that they waited until indexing was complete is somewhat questionable.

There is also disc encryption which can take days to complete. I don't know what kind of resource drain this in on the system but if minimal it's still not a positive for the battery. One nice thing about ML over Lion for users like me and irnchriz is that we can use FireVault2 (CoreStorage) our additional internal drives by Option-clicking on the drive in the Finder sidebar and choose encrypt, instead of using Terminal to do it manually.


edit: 1) For those that do want to use Terminal for this task this tutorial explains it pretty well. You can use it to check to see the status of your encryption process.

2) One of the problems I had with File Vault is that with Leopard and SL Apple only encrypted Home Folder (~/me), not the boot drive. For me, this was great because I use OptiBay and ahve mad my 1TB HDD my Home Folder use the Advanced Options in System Preferences » Users (showing below). With Lion and ML File Vault 2 will encrypt your boot drive which kept my Home Folder, the 1TB HDD, completely unencrypted.

Now to get around this issue I just used Terminal to manually encrypt that drive. However, there is another challenge for me since my entire external drive is my Home Folder. If I go to log in it can't because my home folder is still locked. I needed to have another account that was on that boot drive so I could log in, unlock the 2nd drive containing my Home Folder, log out and then re-log in with my regular account. I created a script to do this automatically but it was still not an elegant solution.

I've sense found this site that contains a script that will unlock your additional drives first specifically for this type of issue.


I understand this all seems like a pain to do but when you have an 80GB SSD that you want for booting and launching apps fast but want to use a 1TB drive for all your media, especially content that gets written repeatedly you want that to be your primary drive. It's unfortunate that 1) Apple goes halfway in supporting this feature, and 2) they didn't use something like this in their RMBP.

So, I have to leave it alone for half a day after the installation until indexing is finished?

I'm not sure of what you're asking. He's not saying you have to leave your computer alone, he's saying that it's working on additional tasks in the background that are a drain on resources so don't expect to get the same performance from the device while these tasks are being performed.

I mean are those tasks just a once-only after ML installation, then things go back to normal and no additional drain? OR are they going to do it again and again the background and drain the battery?

No one ever suggested that you have to leave your computer alone for half a day after installation. You simply need to understand that there are things that need to be done and that the computer will be doing some background tasks while you are doing other things and these background tasks can affect battery life. So it is not surprising that you get a reduced battery life the first day or two.

1. Indexing of the hard drive.
2. Disk encryption (if you turn that on)
3. Time Machine backups

Now, if you install a new OS and then immediately throw the computer in your briefcase for an overseas trip, this might cause you a problem. But it would be rather foolish to do that, anyway.

As for Windows, if you choose to use an inferior OS with more limited capabilities, that's your choice.

One time after installation of the OS. There will be tiny amounts of time later (for example, every time you create a new file, it has to be indexed). I guess if you copied over a few thousand files all at once, you might notice more indexing going on, but under normal use, you won't notice it after the initial period

You are conflating two different things. No one in their right mind would claim that OS X (or any other Apple product) doesn't have the potential to have problems. Apple has the Genius Bar for a reason. The difference is how common, how frequent, and how troublesome issues are across the different OSes. To say that OS X has some flaws equates to what Window users experience is disingenuous. Even when Windows is working optimally it's still a bigger pain in the ass than the newly released Mac OS not being as efficient as the previous Mac OS version.

Do you think Windows is collectively a more efficient OS to use over Mac OS? I don't, and I use both daily. There is even testing by AnandTech that show that Windows gets less battery life than Mac OS on the exact same system. I'd like to see some tests to see if even with the ML battery issue affecting some users if it's still not better than Windows.

Totally agree with this comment. I bought the MBP non retina last month deliberately and have no issues at all on battery life after upgrade to ML. I have used the MBP on same routines and still getting exactly 7 hours or more.

What everyone on this thread is doing is missing a simple hardware change. A retina display on a MBP is also brand new and there is limited data on its overall performance, of course it saves power with flash memory but the big but is ML exploits features like power nap, graphics etc that EAT up power. ML runs flawlessly and I have hammered it.

Look at the whole Apple package and if dissatisfied go change back to your old windows laptop, other than a Vaio good luck if you get more than 2 hours.

Stop the whining on this thread it's says more about the writers than any perceived problem with ML. Apple will solve issues with RETINA MBP soon, as always!

You are right there. Anything negative that can be dug up or manufactured is blown up as far as possible. I've pretty much given up on the Apple Support blog, it is filled with trolls, probably paid ones, pumping in as much fud as possible which is a shame as many newbies go there assuming it is all gospel. I wish Apple would monitor and edit that system.

The Menu bar shows a spinning wheel and won't respond when I hover the mouse over it -- I go to Activity Monitor to find SystemUIServer taking up about 54% CPU. I hit Force Quit, the process restarts itself, then all is well. 

 

Again, an annoying problem I never had with Lion.

I ended up doing a clean re-install of ML instead of upgrading from Lion.  I like clean systems.  Other than that, been a solid update.  I am looking forward to 10.8.1 to address these and other potential issues that I'm reading with other people.

I upgraded my 2011 MBA the day after the ML release.  Clean-install too.  Been working just fine with the exception of the battery life taking a hit.  Fortunately, I leave it plugged in the entire time at work so I'm not impacted by it really.

Let's get these fixes in Apple.

 

On the page that I pointed to is this statement:

 

If your Mac appears to be running normally but isn't responding, force the computer to shut down by pressing and holding the power button for 10 seconds. Note: You will lose any unsaved work in any open applications.

 

On the iMac, one is then instructed to pull the power cord, wait 15 seconds, reconnect the power cord, wait 5 seconds and then restart the computer. This resets the system management controller.

 

All the best.

I use a 17" early 2011 MacBook Pro and battery life has been the same, if not slightly better than Lion.  Worked find the developer previews as well.

All the best.

There is also this from the SMC support page: http://support.apple.com/kb/HT3964

Resetting the System Management Controller (SMC)

Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

  1. Shut down the computer.
  2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
  3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
  4. Release all the keys and the power button at the same time.
  5. Press the power button to turn on the computer.


Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

To say that OS X has some flaws equates to what Window users experience is disingenuous. Even when Windows is working optimally it's still a bigger pain in the ass than the newly released Mac OS not being as efficient as the previous Mac OS version.
Do you think Windows is collectively a more efficient OS to use over Mac OS? I don't, and I use both daily. There is even testing by AnandTech that show that Windows gets less battery life than Mac OS on the exact same system. I'd like to see some tests to see if even with the ML battery issue affecting some users if it's still not better than Windows.

 

With regards to the battery life I don't think it's quite fair to make a broad statement on OS X vs Windows battery life based on a system using solely Apple's drivers.  Most of the gap in the battery life is probably due to their drivers with a little being due to Windows. 

 

With regards to upgrades: Windows 8 upgrade has been exceptionally fast for me and nice to warn me about issues with specific programs.  10.8 however just disabled them when they weren't compatible. I wasn't aware of any advanced warning on that(correct me if I'm wrong).

Sure I can. There are measured tests that show a distinct difference in battery life using the same HW. You can argue that Apple's BootCamp drivers aren't as good as their Mac OS drivers but that's part of the reason why Macs perform better. Apple designs their PCs and OS so they have control over how the power is managed. They also have a very small number of products to test for compared to all major OEMs and MS. I'm not sure why you would discount this. It's this advantage that makes Macs that much better than the competition. You've also only mentioned drivers without any mention of how the Windows itself could simply be less efficient than Mac OS.

I wish Apple would monitor and edit that system.

The other problem with the Apple Support Forums is the nature of the messages. Let's say that there are 5,000 messages on a particular problem. Of those:

500 are messages from people who experienced the problem (but see below *)
3,000 are from people who don't have the problem
500 are from people calling the first group trolls
100 are from people trying to help the first group
900 are from people simply posting that Apple six

* Of the 500 messages from people who experienced the problem:
400 are from a group of 10 people who posted 40 times each. Of those 10, 8 of them screwed up their system with various hacks and only 2 have a real problem
50 are from people who see it as an opportunity to make Apple look bad so they simply pretend to have the problem
50 are from paid shills

So, out of millions of devices sold and 5,000 Apple Support messages, two people actually have a problem.

I have found it to slow down my machine considerably. Not all the time, but there are long pauses at times when everything seems to be running in molases. 

 

Mail seems to be part of it taking longer to do many tasks and inexplicably chewing up cpu usage.

 

Then there is the memory issue. I have to run Free Memory a LOT more often than before ( great utility - you should all have it) - and this brings the system to a halt.

 

Perhaps some of the power usage is do to thrashing.

Battery life is already bad on my mid 2009 MBP with Lion. I am lucky to get 2 hours of service (using lowest power settings, integrated GPU, etc..)

 

Apple didn't think my 77% health battery had degraded enough in June to fix it before my AppleCare ran out and now I am stuck.

 

I am definitely going to wait for this to be cleared up before I upgrade.

Sorry folks but I don't seem to have any issues at all. I'm running MacBook Air that I bought just 2 weeks before the WWDC (no free upgrade for me). I do wonder though if the Power Nap feature has something to do with it but aware this is only available to newer kit so probably not.
