Mountain Lion OS X 10.8.1 Improves Battery Life Somewhat

My 2010 MBA 11 is still draining about 2-3% per minute with nothing running. :mad:

That's a different problem. Don't wait around for an OS update to fix it because it won't.

Call Applecare, use the support site, post on your favorite forum or whatever troubleshooting option is appropriate for you.
 
thank god i have a snow leopard compatible mac! they start to have a huge value! like the apple tv 2 lol
 
Could it simply be Messages/iMessage constantly checking for new messages? Or Notification Center doing its thing? Or iCloud syncing? Or how about all of them?

1/3rd or 1/4th less battery is quite a steep price to pay for those (admittedly nice) features.
 
I have a 2012 MBA 128GB i5, and I just got ML a couple days ago to be close to the inevitable .1 update to an update. I haven't seen a huge drop in battery life, but straight away I A) Disabled all notifications, B) Turned off automatic update. I have however noticed when running Xcode my fans are at full speed, and the unit heats up dramatically.

My suspicions are that since apple is pushing very hard for iCloud everything, its constantly hogging resources in the background, checking in, asserting location etc. You couple that with the new air-play mirroring, messages, and whatever other new packaged item not optimized yet and I can see how some slightly older models would see a huge hit in battery.
 
My battery life improved

My battery life improved after updating to 10.8.1.

Battery life under light usage (Mid 2012 cMBP 15", 2.7 i7, hdd, 25% brightness - I'm currently in a dark room, web surfing, and microsoft word open, connected via ethernet with wifi off.)

With 10.8 under the same conditions above, I would get roughly 5.5 to 6.5 hours at 100% battery. So I'm very happy that I've reclaimed some of my battery life back. :D

Here is a screenshot of my battery life when I'm just using Microsoft Word.

-Also: I am using gfxCardStatus with it set to only use the integrated graphics card (HD4000)

No improvement

After upgrading yesterday morning, I ran two test on the new software to assess battery depletion from full..and re-charge to full.

1st was to let my MBP ( mid2009) run from 100% charge to for 50% - elapsed = 1 h 54 m.. To re-charge 2h 11 m. I went back and compared these with data gather from ver. 10.8.0. The results were litterally seconds apart. So SOMEWHERE, we've lost about 3HOURS !!!!

What's up with that !!!????

I've posted about this here already. It was never an issue until the minute I updated to ML though, so I'm a bit unsure of how it's a different issue.

Good thing the iMac I installed ML on won't need a battery any time soon. :cool:
In the mean time, I think I'll keep my Macbook away from this upgrade until Apple gets their act together... :rolleyes:

With yearly OS updates we may never see that again. Some things are nice about quick system updates. This is not one of them. We need some pressure from our 3rd party software & hardware developers to force Apple to go a little or maybe even a lot slower with new major system updates.

Too many bells and whistles. The OS is being dumbed down for non-pro users who need useless eye candy to keep their attention.

Yup, all us non-pros are simpleminded monkeys who like shiny things and stupid eye candy.

Yup, we non-pros are all morons and mouth breathers, unlike you super cool, sophisticated pros.

Please forgive us eye candy loving, dopey app using, short attention span morons for ruining things for super pros like you, angrynstupid.

(I must say, your username...well...)
 
No problems here

I have a mid 2012 MBA 13". And I've had no battery problems at all!
I've been using it for 2.5 hrs and it's setting at 89% with 9:03 remaining:eek:

One good terminal command I use is:
top -o time -s 15
this sorts task running by cpu usage. And allow you to find cpu hogs.
 
Counting myself luck I guess. Updated yesterday to 10.8.1 and charged up last night to 100% and opened it this morning at work at 7:45 and currently on track to hit more than 9 hours with Mail, iMessage, Safari and iTunes constantly.

Lion = Vista, or Apple Vista
Mountain Lion = Mountain Vista?

You are just one of the growing many that see the updates of the Mac OS to 10.7 & 10.8 as anything but an upgrade. But my late 2010 17" MacBook Pro will not run Mac OS 10.6. For that reason I am stuck with having to run at least Lion.

I have a list of things that I do not like about Lion &/or causes me to have work slow downs. None of these items were ever fixed or even partially repaired. Now Apple has moved on to Mountain Lion. This means that Apple is now copying Microsoft in that OS updates are no longer upgrades. Windows 7 was a big upgrade from Vista. Windows 8 appears to be just an OS update, but is lacking in so many ways to be called an upgrade. Or did Apple lead here with the Snow Leopard to Lion & now to Mountain Lion with these updates that are not upgrades.

My Macs are not my iToys & thus should have a very different OS. I even scroll differently with no problems remembering which is which.
 
...

True... how many of us need to constantly keep in the back of out minds when we use a standard PC ("oh dam..... i need to scroll differently")

While, its true its an "option" of reverse scrolling on OS X, Apple prefers to call if a "feature" of being different, while at the at the same time, being more "convenient"

Maybe this is why us Apple users call it "staying in Apple's eco-system", coz to the average PC user, it will freak them out.

My mate never used a Mac, but he constantly must remember to "push to scroll" as I prefer this option. :apple:
 
...

5 hours, 40 mins here on 10.8.1

But i am running Parallels.... so thats expected. even on full charge.

I don't understand how Apple let this happen. They own both the OS and hardware, and ML is targeted for only a small subset of its computers.

There's two possibilities: 1) Apple's QA department is going to ****, 2) Apple's QA department filed bugs for this stuff and was ignored, probably due to execs demanding a ship date was met

Mac OS X Mountain Lion is obviously doing more things in the background, thus eating battery life.

Every new release of an Operating System won't necessarily have better battery life. An algorithm to speed things up might take more processing power, thus reduce the battery life.

You can't simply file a bug to 'increase battery life'. That's ludicrous.

You can't have a tiny little battery and a whole bunch of cloud/notification/useless pinging, etc., and expect good battery life. They need to tone it down or bring back the thicker batteries. They may be over reaching at this point. Something has to give....
 
...

Now I know where Apple gets their power...

Its more "convient" to just add 4 battery packs to the Retina internally, to give it more juice, than to built one huge battery in....

Seems Apple could of done this no ? Its not like its user replace-able anyway, so it wouldn't matter to the consumer.

Current size of a battery pack could be expanded, an/or make the cells smaller, so that extra space could be used for other stuff.
