My macbook pro battery life is tremendously reduced after installing lion os x

I installed Lion OS X on macbook pro 13 inch- i7
I noticed that it was 100% battery full and the remaining time was less than 2 hours.
When I was using the snow leopard, it was said 6 hours which is fine.
How to solve this problem please.
Best regards,

Hi all, thought i share some of my battery related issues i have with Lion.
As everybody already noticed, even my battery life took a deep dive into nothing really. From steady 5 hours to 2 hours !? I use my mac a lot on battery, and i can make it through the day whitout even touching a charger. But .. now that has apparently changed.
So, what i found out after installing Lion is 3 things ..
#1 "Kill your daemons" .. after i examined the Citrix fix, which i didn't had installed i had a look at what daemons i had loaded, and found a lot of google ones. So i killed those, whenever a use chrome i just have to manually check for updates. No biggie.
#2 "Battery calculation is different" Yeah, it really is .. it seems like they changed the way the calculation is done. Its more dynamic now, and it taking in consideration more about what you're doing atm on your mac. When iam writing this my battery is at 70% and i says that i have 4 hours left. When i start to surf for example it drops to 2 hours. I did the battery calc reset, altho it got a little better but not good still.
#3 "Dynamic switching" Nasty one, it seems that after i upgraded to Lion my Dynamic switching of the GPU stopped to work. All settings was according to the book, but still i had my AMD chosen all the time, which explains the furnace i got on my lap all of a sudden. So, since by default there is no way to switch the GPU i downloaded the gfxCardStatus that did the trick for me, temperature dropped radically and my battery time went up of course.
So, now iam back to almost 70% of capacity before installing Lion, and that with doing nothing other than just install Lion !. I know there is issues with Flash, and most likely there will be a fix soon from Apple and Adobe that fixes our battery issues.
Then there is the wifi issues, that everyone seems to have in different forms and shapes, so basically Lion needs a haircut and a shave.

  • MacBook Pro 13 " going slower in performance after Installing LION OSX

    Hey Guys ,
                        I had noticed some problems in my MacBook Pro 13" which I bought in the MID of 2011 ( i5 processor ) , I had purchased and installed LION OSX and observed after installing that my Backlite ( Keyboard ) dont get on when I start up at the LOG IN , which used to work in SNOW LEOPARD .
    Booting takes SO SO SO long as when comapared with the previous OS .
    Heating Problem is also a must to mention .
    If you guys know how to reduce these problems please help me out !
    Thank You .

    I'm curious if you ever found a solution for this issue.  I recently purchased the SanDisk Extreme II 480GB, replacing my OWC Extreme Pro 240GB.  The OWC never experienced the "slow to wake" issue whereas the SanDisk drive does, consistently.  To make sure I'm having the same symptoms, this is what happens to me:  Put the mac to sleep (either manually or letting it do it on its own, waiting for the led to pulse showing that it is asleep), then wake it up (press a key on the keyboard), the logon screen shows almost immediately but as soon as I try to type the pinwheel/beach ball shows up, I wait between 20 and 30 seconds and then I'm able to type and all is well.
    I contataced SanDisk and their support was horrible.  They simply told me "contact MAC for this issue" (no joke, not "contact Apple" but "contact MAC", in all caps).  I explained that it works fine with the OWC drive just not the SanDisk.  They replied with another article showing that all macs have trouble waking from sleep (not true). I replied again indicating that I've never had this issue with any of my 3rd party drives, only this SanDisk.  Then the replied simply stating that all mac's have issues with 3rd party hard drives when waking from sleep.  At this point I threw a fit and yelled at my screen, even though it wasn't my screens fault.
    In any case, their support has not been willing to do any actual troubleshooting.  I'd love to return it and I might have to - but as you stated, it's annoying to have this issue but the performance is fine the rest of the time.
    Thanks for any input you have.

  • Macbook pro freezes for no reason even after installing 10.8 on a brand new hard drive

    Macbook pro freezes for no reason even after installing 10.8 on a brand new hard drive.
    Tried to reset pram, smc, nvram.
    Tried installing new RAM.
    Tried installing new hard drive.
    You should know that my internal drive is installed in a cheap external case and plugged in a USB 2.0 port because i am waiting for a new hard drive cable.all
    Yep all good things happened to me...i don't know if all these problems are linked, ahh and also my trackpad is behaving very erraticaly sometimes, it's like it is possessed by a ghost. My computer is not under warranty anymore so i'd like to avoid a trip to the Apple store but i'm close to doing just that.
    Any help appreciated...

    It's diagnostic software. It's supposed to help you find problems. I don't think anyone is making any software yet that fixes hardware problems.
    That said, the two comments:

    .....also my trackpad is behaving very erraticaly sometimes, it's like it is possessed by a ghost....
    would lead me to think it's the logic board. On older MacBook Pro's both the USB I/O ports and the keyboard/trackpad are fed out of an integrated USB controller integrated into the South Bridge I/O controller. On newer models, the USB ports come out of an integrated North/South bridge controller and the keyboard/trackpad are handled by an SMC controller, which itself interfaces with the I/O controller. All of these items are on the logic board, and they're all unrepairable.
    ...unless of course the "internal drive [that] is installed in a cheap external case" is itself causing the problems. Another thing to try might be a different USB port, if you haven't done so already.
    I didn't know the price for Scannerz went up. I could have sworn I only paid 30-some bucks for it. Maybe it was on sale at the time. I don't remember.
    In any case, good luck.

    The battery on my son's mid-2010 15-inch unibody macbook pro has a cycle count of 360 and shows its condition is "normal." What is the normal battery life on this computer? The reason I'm asking is that the trackpad is malfunctioning and he was told the battery could be the cause of the problem.

  • MacBook Pro Battery Life Draining After Updating to Yosemite

    Hi,
    I have a 2011 MacBook Pro. After updating to Yosemite a few months, I have experienced a severe loss of battery life. I was averaging around 6-8 hours on a charge, and that is now down to about 3. I have reset the PRAM, etc. and SOMETIMES that will work but not always. I typically have only one program running at a time, Chrome, but sometimes it's a mix between Chrome, Windows, iTunes. But my computer usage patterns have not changed since before/after updating. The only thing I can think of is that it is caused by Yosemite.
    When I check my Activity Monitor, the apps with the highest CPU usage are WindowServer, kernal_task, and Chrome Helper. I have also disabled several plugins/features of Chrome to no avail.
    Has anyone experienced similar issues or have any suggestions?
    Thanks!

    Is one of the 'etc.' a SMC reset?

  • OS 10.10 Yosemite and Macbook Pro battery life

    Greetings,
    I have a mid-2012 Macbook Pro 15" that was getting 6-7 hours of battery life before installing Yosemite a few weeks ago during the initial public release.
    Within the last week or so, if I am lucky, I now get maybe 3 hours before I'm down to less than 30%.
    Twice this week, I have intentionally gone down to less than 5% before letting the laptop recharge for at least 12 hours before using it again, thinking maybe some sort of memory was being created; and it still drains power quickly.  And with the new formatting of the "about this Mac", I have not been able to locate how many cycles the battery has on record.
    I'm not watching movies or gaming.  E-mail, Facebook, and web surfing.
    If anyone has constructive ideas, I would be very appreciative.
    Thank you for your time.

  • MacBook Pro Battery Life: Linc Davis please help!

    Hello
    I recently upgraded my operating system to Lion. I noticed that the battery life has changed dramatically. Before the upgrade, the battery lasted about 7 hours but now, it doesn't last more than 3 hours. I am thinking that the upgrade has something to do with it. What should I do now? I read something about recaliberating the battery but a lot of comments from the users said that it didn't help them. Do I need to roll back the upgrade and go back to Snow Leopard? If you have any suggestions or ideas, please post them.
    - What is the ideal use of a MacBook in terms of the battery life? I usually charge it and keep using it until the battery is almost empty. Is that good or do I need to keep it plugged to a power source if I am not mobile?
    - In case I format my computer and go back to Snow Leopard, what happens to all the programs that I purchased from the App Store? How can I get them back?
    Thanks

  • Late 2013 Retina Macbook Pro Battery Life

    I am getting around 3-5 hours of battery life with my late 2013 rMBP with brightness turned down, bluetooth off, Wi-Fi on, forcing integrated GPU, and using safari w/out flash.
    I've seen other people with the early 2013 model get 10 hours!
    I used migration assistant to transfer my data across to this mac when I started using it a few weeks ago.
    I have included a screenshot showing my current usage.

    Any solution other than fresh install?

    Hello, raikun. 
    Thank you for the question.  The first thing we need to look at is the health and condition of your battery.  This first article will show you how to process this.  Be sure to test the results after each troubleshooting step processed.

  • Macbook pro battery loss 2% of capacity after 1 week

    I bought a brand new macbook pro 13" (entry level) 1 week ago. I was concerned about maximizing my battery life since I want to start fresh with this new computer. A few days ago I calibrated the battery just to make sure everything was set. I just learned how to check the battery health and charge cycles in the "About this Mac" menu, and my charge capacity is 5685 (down from the design capacity 5770), after only 5 charge cycles. Is this normal?

    Hi mdudley28,
    To be expected. Over the first several weeks/months of ownership, especially with an initial calibration (or two... or three) the full charge capacity will fluctuate. I've seen it bounce around by as much as 400 mAh, what's important is that it bounces back. If it continually loses mAh but never recovers and dips to sub 80% of it's original capacity then that is cause for concern and something you'd want to take up with Apple.

  • 2009 MacBook Pro - Battery at only 87% capacity after 5 months?

    Hello,
    I purchased my MacBook Pro in November. System Profiler and CoconutBattery report my battery capacity at 4756 mAh, or 87% of the initial 5450 mAh capacity. I've followed the steps to calibrate my battery twice over the past two weeks, which brought it up one percent from 86% to 87%. I've done, apparently, 82 charge cycles.
    Is there a problem with my battery? I don't have AppleCare, but am assuming that a battery replacement is the kind of thing covered under warranty without it.

    It is definitely on the low side for a battery in an MBP13, nusilver. These batteries are rated to 1000 cycles at 80% of original capacity (compared to SU's older model which is rated for 300 cycles at 80% capacity). My own MBP 13 , after just over 100 cycles since August last year, is still sitting on over 98%.
    They may not be prepared to change it until it drops below the "official" figure of 80%, but I'd certainly take it in for testing to an Apple Store or AASP. A battery that has lost capacity at this sort of rate is likely to fail a "stress test" in which case I suspect they will replace it immediately anyway.
    Cheers

  • MacBook Pro Retina Late 2013 UI Lag after installing Yosemite

    Hey everyone,
    Ok so my Issue here, and I think I'm not the only one but my MacBook pro retina late 2013 (8GB ram, 256gb SSD) has been experiencing numerous issues after installing Yosemite. For example, the UI lag is at times horrible; after opening several apps, and especially after having a pdf or two open in preview everything becomes so sluggish. the animation of switching to mission control is painstakingly slow, and opening new tabs in safari takes 2 or 3 seconds. I've done a clean install of yosemite but nothing seems to help, what should I do; just revert back to mavericks and cross my finger for a future update?
    Any help would be much appreciated, thanks so much !

    i am in the same situation as you, late 2013 retina MacBook Pro 15 inch upgraded to yosemite and then clean installed yosemite b/c of UI lag after opening several apps at once... I found that yosemite drained my battery life too, on mavericks i was getting 5-8 hrs of battery life, on yosemite i was getting like 2-3 hrs most.
    After exhausting every option out there (apple store genius bar help, apple repair, etc), I came to the consensus that my macbook had no hardware problems at all, it's basically a software problem on apple's end.  and until they update yosemite with a specific fix for the UI lag and the battery consumption problems, i am not going back to yosmemite. 
    what i did was clean installed back to mavericks... this solved every one of my problems, NO LAG, NO BATTERY ISSUES, back to buttery smooth performance, of course without the new UI however... but i can live without new design
    this experience tells me several things: 1. the new apple under the leadership of cook is slowly but surely sacrificing quality of software for unnecessary updates(sales) 2. mac hardware is still good but who knows for how much longer

  • MacBook Pro won't wake from sleep after installing Snow Leopard

    If my MacBook Pro is running while closed with an external display and I unplug it from the display it goes to sleep - as indicated by the white light and the front pulsing. If I then open the MacBook the display remains blank and it is completely unresponsive to any keys or track pad input.
    The only thing it responds to at that point is holding the power button down until it powers down and then restarting - loosing all work in progress at that point.
    Before installing Snow Leopard the Mac would wake reliably when opened from this state.

    Mike Doolin wrote:
    I think I may have found the fix for this. My MacBook Pro was dying in its sleep every time (after installing Snow Leopard), whether it went to sleep automatically or I used a Hot Corner. I went into System Preferences>Desktop & Screen Saver and changed the screen saver to Flurry, and it works now. I had had it set to a folder containing a single .pct file that I had created.
    Good advice Mike! When in doubt check the ScreenSaver settings.
    Definitely seems that it has a problem with that pic... In my case, selecting any images instead of the default setting (no screensaver) seems to have cured my non waking issue on my early Macbook Pro in Snow Leopard.
    My original problem was that no amount of trackpad input woke it, but the space bar did. The space bar seemed to wake it up with the previous Screen Saver setting. Now trackpad wakes it up (even from total sleep as well as screen saver), too. Might be nice to know about if this is an intended 'feature' as a security trick. Otherwise I consider this a bug.
    My vote is that it's a bug.

  • MacBook pro 2009 is slow and freezing after installing mountain lion. Cannot get iPhoto to open fully, other apps are freezing.

    Help! I thought I was doing the right thing by installing Mountain Lion on my 2009 MacBook Pro. It took forever to download correctly and now it is performing so poorly (freezing during applications, have to use force quit, have to use power button to shut it down, etc.) that I wish I never installed it! I want my old operating system back!

    Boot in safe mode.* This will cause certain caches maintained by the system to be rebuilt. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
    Safe mode is much slower to boot than normal.
    When the login screen appears, reboot as usual (not in safe mode) and test. There's no need to log in while in safe mode.
