Mountain Lion Drops Battery Life and Freezes Often, Mountain Lion Drops Battery Life and Freezes Often, Mountain Lion Drops Battery Life and Freezes Often

I use MacBook Pro 13", 2011 edition. Since I installed Mountain Lion, my MBP's battery life drop from 7+ hours to roughly 5 hours overnight. Worse still, it freezes about once a day. Does anybody else experience this? Got tips to troubleshoot these issues?

I initially had similar issues with Mountain Lion, however I thought it was isolated to my configuration. I did make some adjustments using the command line power management tool and the difference are night and day. I never thought it amy have been a change in Mountain Lion. In any case, given the prevalence of this, I created a blog listing the changes I made and explaining it for those with increased interest.

Battery life drops after Mountain Lion and then hard drive crashes. Coincidence?

On October 20, I purchased and downloaded Mountain Lion for my 2009 MacBook Pro. I soon began seeing a decrease in battery life. When hovering over the battery icon to check the time left, I noticed it said "Service Battery". The notebook otherwise seemed to operate normally. I should also note that I've never had any other problems with this MacBook Pro. By November 18, without any other problems, the hard drive crashed and was irreparable, costing me over $200 for replacement. This should not be a part that needs replacement on a 3 year old computer. Coincidence that these events happened so close in sequence, I think not. If the battery problems are known to Apple through the discussions on the Support Communities, why hasn't Apple issued a patch 4 months after the release of Mountain Lion? The new hard drive was installed running Snow Leopard and I intend to keep that OS. It's really a shame because ML has some nice features that SL does not offer. I also will not be purchasing any new Apple OS until the program has been out at least a year to allow Apple to work out the known, potentially costly problems that they seem to knowingly ignore. I'm a loyal Apple customer but this incident will have me thinking twice before running out to purchase any of their products and software immediately upon release or even a few months after.

Have you followed these instructions, specifically formatting your new HDD?

Do Not post stuff about how Airplay doesnt work, because i dont have Apple TV and dont need to hear about it.

If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

Wireless driver triggers warm/hot macbook and low battery life after OS 10.8 mountain lion upgrade

Hello frustrated Macbook users.
I have tried to get help on other Apple discussions but no one seems to want to help, they aren't actually reading my posts, or they hate me for some reason.
No matter.
If you have a warm Macbook that has 2.5 hours of battery life where you used to have 4 or more, please do this simple procedure and write the result below.
Turn OFF Airport wireless networking
Perform an SMC reset (Power Manager)
Connect an ethernet cable and use your Macbook normally. (but do NOT turn on wireless networking again)
How is your battery life after doing this?
I have a user over here who reclaimed decent battery performance if he doesn't use his Airport wireless.
I need confirmation.
If so, I may get a USB wireless adapter and see if the battery life stays good.
Bonus points: If you have a Mac compatible USB wireless adapter and got good results by turning off the built-in adapter, want to test it for me and report the results?
Thanks and good luck!

UPDATE:
Problem persists when using Recovery Partition.
Chance sthat it is third party softwae or updates is more or less eliminated.
Update 10.8.3 beta fixed the problem for one lucky early adopter.
Hypothesis: New battery charging algorithms programmed into Mountain Lion OS10.8 triggered problems from design flaws that were NOT an issue for OS 10.7 and before.
Battery replacements were successful where the replacement battery was built within tolerances that did not fail under 10.8's new charging algorithms. Other bateries did not meet those tolerances so you would get spotty results from battery replacements. It worked sometimes, but not always.
OS 10.8.3 may have adjusted these algorithms to be less demanding on the features of the battery that were failing.
Official word from Apple is 'mum'.

I just recently installed mountain lion and an update for SMC firmware to install power nap. Everything is working except for the menu bar, the icons native to the system do not respond, and features like the clock and battery meter freeze.

I just recently installed mountain lion and an update for SMC firmware to install power nap. Everything is working except for the menu bar, the icons native to the system do not respond, and features like the clock and battery meter freeze.
When I mouse over the icons, the rainbow appears as if it was processing something. The problem is eliminated when I restart my computer but it comes back after a while.
I guess I cant make a backup copy and restore the whole disk because the copy would be made with this error.
Can anyone help me? Anyone with the same issue?

Update: I was able to test out the HDMI adapter as well and the same issue occured. I'm stumped. 10.8.1 maybe.

Hot battery and short battery life after download of Mountain Lion.

Hot battery and short battery life after download of Mountain Lion. Any suggestions?

As in, shortly after install?
Note after you install Mountain Lion it's likely that the Spotlight index will be rebuilt. This will take some time and the machine will run hot. After this completes, which could take 1-2 hours, things should return more to normal.
If they don't, I suggest running Activity Monitor and seeing if you can trace what is eating up CPU cycles.

Battery Life Degrading after upgrading to Mountain Lion.

Hi Community Members,
Just after purchasing the Mid 2012 Macbook Air 13", the battery life was good 7+hours for usual use, including browsing, emails, vpn access etc. After upgrading to ML on 26th July 2012, the battery life depleted down to barely 3.5 hrs now, very disappointed with this experience barely after a few weeks of this new portable. Tried some workarounds for like the SMC reset, uninstalling Flash etc but no success. Don't have power nap enabled which a lot of people feel is the reason for the battery draining out. More concerning is that the FCC ( Full Charge Capacity) has dropped to 96% ( 6431 mAh) from its original 6700 mAh with the Power Cycle count as 24. Spoke to Apple Care today and has been advised to do a Battery Calibration and then get the battery checked up at an Authorised Service Centre. Apple claims it has nothing to do with the Mountain Lion upgrade. Will come back with more updates tomorrow.
Any workarounds or success stories with others ?? Very unhappy and disappointed with my new Mac !!!
Cheers

Mountain Lion EATS-UP RAM and BATTERY!!!

Since I had the BAD idea to install Mountain Lion I have had only trouble.
1) Given the fact that Safari deosn't start and hangs endlessly, unless I ALWAYS force reload the pages, and given the absence - a REAL LOSS! - of functionalities like RSS which were in Safari 5.1.7 but not in Safari 6, I had to drop it as my favorite browser after MANY YEARS, and pass to Firefox which is FLAWLESS.
2) Another MAJOR issue that I want to mention is the fact that with M.L. my free Memory at startup, with the same login items, has gone down from an average of 6.9/7 Giga to a 5 Giga or less.
Even freeing memory doesn't help.
3) The other problem is a HORRIBLE DOWNGRADE ALSO IN BATTERY LIFE which has STARTED the moment I installed M.L.
Instead of the usual 7-7 1/2 hours, I now get about 3 1/2 hours.
I have done PRAM reset and permission repairs (which, BTW, take EVEN 10 minutes!!!) but to no avail.
And on top of it, EVERYTHING is much slower than with Snow Leopard!
A MAJOR SYSTEM UPDATE IS NEEDED URGENTLY!
This system for now s*u*c*k*s feet fungi! ...And one cannot go back to the previous system!!!

Thank you Thomas. Some common sense, respect and politeness helps.
Unless... I have no right to be upset at a system that was put out and for which I even payed (a first in 25 years for me with Mac) and someone finds "offensive" (who is he, the system's mom or child?) some very harsh (IMHO with reasons) criticism of this system!
To begin with, it would REALLY help if, INSTEAD OF SHOOTING answers which are NOT answers, one took the time to read the question well and to try and understand if the person who asks is a newbie or not (in my profile there is a 25 years of Mac experience), and may be NOT insisting on the creation of a new user account when a few messages above I had already written that:
"I not only created a brand new user account, I actually ever re-formatted the whole disk and re-installed the system ANEW, one week after the first install and after innumerable problems, and NOTHING CHANGED".
I consider the REPEAT of such a suggestion just disrespectful, since I had written that I had already done all that and more, and I find it also also upsetting, after one week of PURE **** with my computer, something NEVER experienced before.
In the meantime, I disabled the [for me] useless and actually annoying "Notifications" even eliminating it from the toolbar, and free RAM at startup jumped immediately UP about ONE GIGA, back to 5.2 out of 8, and, after using freemory pro (even if it really bugs me to have to do that everytime I startup!) I gain another giga, and I am back to something more normal like 6.2 out of 8.
However, no way for me to have Safari start without forced reloading (while Firefox is flawless) and I also still have the rest of the BUGS, not last of which is with Mail showing the "blocked plug-in" (after re-installing a brand new FlashPlayer with the new system installation) and not allowing Control-F in address field, which I had done since Mail was invented.
As another person, probably another "idiot" like me who doesn't know that Mountain Lion is perfect and it is all his fault, (I quote him): "I send out 'stuff' to a distribution of people (Bcc, of course) and always take pains to remove the original sender from the list. I then used to put the cursor in the list of distributes, hit Command + A then Command + F and "find" whomever it was I needed to omit. This handy feature is now disabled. Sigh."
I really resent that some people at Apple are so much under windoz influence that they have been eliminating one by one the great characteristics that made Mac a DIFFERENT system, above all a USER FRIENDLY SYSTEM.
Now it is much less so, and on top of it you have Mac users in this forum, who probably started with a PC (which I NEVER touched) who get upset when one points out the flaws in the new creations...
Besides some politeness and empathy, he should learn some English: it is "in the same VEIN", not vain...like his remarks... ;-)

Battery Life ***** on Mountain Lion!

About a week ago I took my new mid 2012 13' macbok to get checked out. The reason for is because the battery was not holding up like I read in the specs. At this time my macbook pro was running Lion 10.7. I upgraded still samething nothing changed until I took my macbook in like I meantion. At the time I took it in I was running Mountain Lion already. So they gave me a new battery everything seem well until a week later I monitor my battery health very closely, so I seen it was dropping quick again. When i got the battery it was in great health and still is but it was at 106% overall health n a week later it was at 95%. I am concerned about what is going on especially with only 6 cycles? Why is this hapenning when I do what is told to do to keep they cells active and have a happy battery. Apple plus look into this battery problem. How many are experiencing the samething?

from experience - when I first got my new Macbook, charge capacity is at 5700 mAh.....after using it for a few months now, my charge capacity has dropped to 5300mAh then back up to 5600mAh and today at 5536mAh...it changes daily and has not affected on how long my battery would last - I'm still getting 5+ hours when I'm doing some online work. 6 hours when just browsing the web.
there is nothing wrong with your battery. battery life does decrease when Mountain Lion is installed but that is more software issue than hardware.
you're under warranty and apple was nice enough to replace your battery.....
why not use your Macbook normally and not worry too much about it if you're gettng 5+ hours in a single charge. Again, you're still under warranty - if things go bad - just get it diagnosed and replaced.
good luck

Updated to OS 10.7.3; fan runs constantly and battery life dropped to under 2 hours when 100% charged. How do I get back to 10.7.2, I don't have a backup prior to this upgrade. This is a newer Macbook Pro 13", no modifications.

Help! This new version of Lion is making me miserable. The fan runs constantly, the computer is hot and battery life has dropped to under 2 hours on a fully charged battery. I updated yesterday, nothing but misery today. Even running the mail program alone make the fan run like I have everything open. Using Pages, iPhoto, and iTunes simultaneously makes the computer blistering hot.Yesterday, I could use all three without any trouble. Any suggestions to either jettison 10.7.3 or how to fix without any expense? I haven't modified this computer at all, it is as it came from the box in August 2011: 2.3 GHz Intel Core i5, 4GB 1333 Mhz DDR3.

I updated to Lion 10.7.3 and started noticing my fans running on high all the time and my battery would drain 2-3x faster. I was going to take my computer into an Apple store until I found this thread. I did the SMC reset by shutting down my computer, plugging it in, and then pushing down shift+control+option while also pushing down the power button. Nothing happens on the screen and the computer did not turn on. I then released all the buttons at once after holding them down for 10 seconds.
After that, I simply turned my computer back on and everything seems to be working fine. The fans are not blasting anymore. I have a newer MacBook Pro where I can't access my batteries. The SMC reset may differ for other types of laptops.

I have an Airport Extreme Base Station and have recently upgraded to Mountain Lion. Now airport utility won't work with my base station so I bought a Time Capsule. For the life of me I can't make the substitution work and only see a blinking amber light.

The Utility transferred all of the AE's settings, so I still have to change the password, which leaves me with only 2 other questions, I think:
1) I assume it's just a matter of using the Utility, entering a stronger password and checking for it to be remembered in Keychain Access. But do I have to change the password for each individual unit-- the TC, the Extreme and both Expresses-- or will changing it just for the TC alone work for the entire network?
Resetting the password you will need to do for each device... the utility cannot even see those old units.
So you will have to do it for each one.. think it through.. because as you change passwords the others will lose connection.. so start from the express which are wireless extending .. change those first.. and go back up the chain.. as each one changes it will drop off the network.. until you reach extreme and change that. Then you might need to reboot the whole network to get everything talking again. If something goes wrong.. just pluck that one out of the mix and plug in ethernet.. reset and redo the setup. That is my preferred method anyway.. do everything in isolation one by one. By ethernet and then nothing goes wrong.
2) Who's the treasonous SOB who spilled the beans to you about the ICBM in my back yard?!?
N.Korean hackers.
[Edit] Whoops-- one more question: I want to partition the TC's disk, but Disk Utility doesn't see it. What do I need to do?
You cannot partition a network disk. And apple provided no tools for it in the TC itself. You can pull the disk out and partition it but that voids your warranty. (although done with care who is to know).
Look at Q3 here.

Mixing TM and data on the TC is worth planning carefully. They don't necessarily sit happily together.

My MacBook Pro w/ Mountain Lion 10.8 is freezing often. What should I do?

My MacBook Pro w/ Mountain Lion 10.8.3 has been very sluggish recently. It freezes often.It is slow downloading from the Internet. Applications are slow to load and sometimes freeze in mid use. If I accidentally click on something that I didn't want to do, and then reclick what I wanted, it gets frozen and seems to take forever to straighten itself out. I try to Force Quit,a dn many times nothing happens.

OS X Mountain Lion Battery Life Issue

I bought a new MacBook Air 13" about a month ago. It has 4GB Memory, Intel Core i5 processor, and a 256GB SSD. The first three weeks I had it (before OS X Mountain Lion was released) it was running OS X Lion and was giving me about 9hrs (using just iTunes, Safari, Calender, and Messages). After I upgraded it to Mountain Lion the battery dropped to about 5-6hrs (using the same apps). Why is this? And is there going to be an update or something that can fix this?

Try the following:
a) Turn off "Enable LAN syncing" (dropbox preferences)
reboot
check if dropbox is back to normal
if not,
b) completely deinstall dropbox (no need to delete your data files, of course)
e.g. http://www.ehow.com/how_8242148_remove-dropbox-mac.html
download the latest stable build of dropbox, currently 1.4.12
install when you start dropbox, make sure Enable LAN syncing is turned off
Hope this helps!

How to extend battery life in Mountain Lion?

I have an Macbook 5,2 and recently I update Mac OS X from Snow Leopard to Mountain Lion (10.8.3 12D58). Current main problem is my battery life reduced from 5 hours to 1:58:00. This is crazy. Are there some applications runs on the back ground? How to uninstall useless applications and extend battery life? Looking forward to get help from this forum.
Best Regards
Stephen Lee

Runaway applications can shorten battery runtime ...
