Lion & Battery Life

After installing Lion my battery life has halved! Anybody else having this problem? What can we do about it?, After installing Lion my battery life has halved! Anybody else having this problem? What can we do about it?

Having a similar issue…
MBP late 2008 version (MacBookPro 5,1)
Was running OS X 10.6.8 and getting about 2.5 hours battery life on average
Installed Lion and now I can watch the battery draining almost in real time! For example, from fully charged tonigh to 69% in 20 mnutes. I'm usings Watts (an excellent replacement for the built in Battery indicator) and it indicates approximately 1 hour left… so since the Lion upgrade battery life has almost halved.
It doesn't seem to matter how many apps are open and whether they are in full screen mode or not, the battery drain is the same.
I have reset the SMC. I have calibrated the battery. I've used the Recovery Partition to check and repair permissions and veruify/repair the HDD used for Lion. All to no avail.
As a further example, since starting to type this post, battery percentage has gone from 69% to 64%… and I'm not a slow typist!
Any other reports and, preferably, fixes would be great.

"mountain lion battery life"

concerned about loss of battery life on mountain lion

I have a 2011 Macbook Air 1.6 i5 128gb SSD 11 inch
I was running Snow Leopard and used to get around 5-8hrs battery, then I moved to Lion and was still getting 6-7hrs battery life. 3 days ago did a fresh install (wiped my hard drive completely), and now only get 2 hrs approx.
The OS is working fine and I love it, but the battery life issue is severe, that i can no longer use it for journey or around the office.
I am looking to wipe again and move to Lion, but need to know when Apple may release a fix and if I should just wait a little longer.

After installing lion, battery life cut by 75% and browser speed slowed to a crawl

My Mac Book Pro was working perfectly fine until I installed Lion. Now my battery life has been cut but a least 75% (only lasts about 45 minutes on a full charge) and it has also affected the speed of my browser.
Can anyone help?

There is a 190 page thread discussing the battery life and health issues assocaited with ML that you will find in this forum located here: https://discussions.apple.com/thread/4135250?start=0&tstart=0 . Some people have had some success in installing the ML 10.8.2 combo pack over their 10.8.2 instance. Some have had success in performing a clean install. Others still have problem, and others have moved back to Lion or SL. In your posting, are you saying you've installed Lion or Mountain Lion? I'm assuming that latter. I've recently reverted back to Lion until I have more confidence that Apple has tackled the issue.

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 can you get OS Lion back if you already downloaded Mavericks? I CANNOT live with the battery life of 2 hours!! HELP

How can you get OS Lion back if you already downloaded Mavericks? I CANNOT live with the battery life of 2 hours!! HELP

Don't downgrade OS X without first erasing the drive. You cannot restore a Time Machine backup of Lion directly on top of a later version of OS X such as Mountain Lion or Mavericks.
When you "Restore from a Time Machine Backup.", the drive will be erased for you, but yes, won't hurt to:
Boot into Recovery (hold ⌘R on boot)
Utility->Disk Utility->Erase Macintosh HD, then Repair Macintosh HD
Quit Disk Utility
Then Select: Restore from a Time Machine Backup.

I have a early 2011 Macbook pro 13 inch, I'm running Lion 10.7.4, and i want to upgrade to 10.8 Mountain Lion. Is it safe for my computer or are people experiencing problems with displays and Battery life?

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.

I upgraded my macbook pro from OS Lion to OS Mavericks. When unplugged, it heats up exceedingly and the battery life is extremely short. What to do?

Installation of the new OSX is very heavy hdd load, in addition spotlight reindexes all the files on your computer - it may be a few hours. If in the future will be the same macbook hot, you should contact your nearest Apple Authorized Service Provider.
May be required to clean notebook cooling system.
You can also install any monitoring utility sensors to your mac such as Hardware Monitor and look at the value of the temperature sensors.

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.

Since I downloaded OS X lion, why is my battery life on my Mac Book Pro suffered

Why has my battery life suffered, since I downloaded OS X Lion on my Mac Book Pro? How can I increase the battery life?

Get gfxCardStatus. It is a free menu bar application that keeps track of which graphics card your MacBook Pro is using at any given time.
<http://www.macupdate.com/app/mac/33905/gfxcardstatus>
When you are running on the battery, you want to make sure you are using the "Integrated" graphics unit, as it is more power efficient.
You might also want to run Applications -> Utilities -> Activity Monitor and see if there are any processes which are consuming an excess amount of CPU non-stop.

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

Runaway applications can shorten battery runtime ...

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?

Poor battery life after Mountain Lion update

I updated OS on my 2011 13" MacBook air from "Lion" to "Mountain Lion."
My laptop used to last 5-7 hours with a single full charge. After installing Mountain Lion, I can't even last 3 hours.
I noticed that other people are experiencing the same problem but I can't seem to find a solution.
Any suggestions?

There's a huge thread about battery life here: https://discussions.apple.com/thread/4135250?start=0&tstart=0 . Hopefully it will be fully addressed in 10.8.2.

MacBook Air battery life/standby time destroyed by Lion!

My girlfriend's 2010 MBA used to be able to be in standby mode forever (for weeks, if not the advertised month) and still maintain a charge with Snow Leopard. After upgrading to Lion, the battery drains overnight.
Anyone else have this issue?
And does anyone know how to solve it? I tried resetting the SMC which seems to have helped battery life slightly when the computer is in use but had no effect on standby time.
Any help would be much appreciated.

My wife's MBA (Late-2010 11" 2GB) had its standby and operating times destroyed by Lion. Prior to the Lion upgrade, useful operating time were 5+ hours and standby forever it seemed. After the Lion upgrade, immediately useful battery life was 2 hours and standby barely lasted overnight. I ran Coconut batttery to discover that, at idle with no applications running in the foreground, the machine was drawing 16.7 watts. The case was also uncomfortably warm when operating on battery. On charge, it showed 434 watts (shocking don't know if this is normal for Snow Leopard though). My MBP (mid-2010 13" 8GB Snow Leopard 10.6.8) only consumes 9 watts at idle on battery by comparison (and it doesn't have SSD and other power saving features available on the MBA).
So, I downgraded to Snow Leopard by reinstalling the machine from scratch. Power consumption in coconut battery shows 5 watts at idle with no applications. When I wake the machine from standby, coconut battery shows 0.1 watt consumption. So, I believe this may have solved the battery longevity problems. Since I only downgraded today, I have to test for some time before I can declare the problem fixed.

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!
meta: short time install snow leopard hours overheating shorter shortened lower

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'.

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
Som
