Reduced Battery Life After 10.6.8 Update - a Solution!

After updating to the latest version of Snow Leopard on my MBA13", my battery life plummeted suddenly from 7-9 hours to 2-3 hours. Genius Bar people replaced the battery under warranty but that made zip difference.
Exploring further I found that the Dock was running the CPU almost constantly at 100% and the fan was going berserk. Kept the breakfast warm though :-). Tracing it further, Parallels (ver 6) was the culprit. I did the following:
1:     Launched Parallels;
2:     Clicked the Virtual Machine (VM) menu;
3:     Went to the Options section;
4:     Removed Parallels from the Dock (left my desktop icon for it alone) by unchecking the 'Show Windows Applications Folder in Dock';
5:     Restarted the machine.
Result?
Dock usage of CPU back to normal, fan silent, breakfast cold, and battery life back to 7-9 hours. JOY!!!

Did the problem persist with the latest version - ParallelsDesktop-parallels-en_US-6.0.12092.670880 - ? If so then you should report this to Parallels as there may be more things needing fixing to eliminate this problem completely.
Oh, and this info is from Kappy, not MacBookProHayden.

  • Horrible battery life after 10.8.4 update?

    Computer: 2010 MacBook Pro 15"
    OSx version: 10.8.4
    I updated my computer yesterday to OSx 10.8.4.
    While I was on 10.8.3 after a startup with nothing running my mac showed 5-7 hours or so of battery life.
    With 10.8.4 it now shows 2-3 hours if im lucky after a startup with nothing running.
    As I post this I started at 100%, I have been using my computer for not even 20 min now and its down to 80%
    The computer shows the battery condition is normal, and my energy saver settings are optimized with graphic swithcing, hard disk sleep, etc..
    Any help will be GREATLY appreciated. Thanks!

    In that case I suggest reinstalling OS X:
    Reinstalling Lion/Mountain Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    This will install 10.8.4 (or should.) If this does not help, either, then take the computer in for service.

  • Battery life after iOS 6.1 update

    After Updating to iOS 6.1, my phone decided to black out with 24% battery an the only way I fixed it was to have someone call me while it was plugged in.  That was the only time the screen worked. I have also noticed on that day my battery didn't last all day like normal but instead was dead by hour 4-5 of usage.  Yesterday, my battery life also continued to be a problem and now this morning even when plugged in the battery says 100% only sometimes, the rest of the time it stops at 98%.  So I unplugged it and tried it again and it kept happening. Would say 100% then if replugged in would say 98%.  So my iPhone started the day with only taking three hours to die from full battery and after recharge and unplugging it is at 98%, not 100%.  Thoughts?

    The problem is more than likely being cause by corruption that occured during the iOS install or in the backup that was used to restore the phone after the update.
    Standard troubleshooting is:
    Re-boot the phone
    Restore the phone from your backup
    Restore the phone as a new device.
    One of the 3 should fix the problem.

  • I Have been getting BAD battery life after the ICS UPDATE !! on the DROID RAZAR MAXX have this happen to any one else ??????

    i have been getting really bad battery life after install ICS on my droid razar maxx i can only go 1 day and 3 hours where i used to be able to go 2 day easy have this happen to anyone else can someone tell me how i can make my battery life better??????/ and do i need to let my phone go complete dead before fully chargeing it again ??????
    before install the ICS update i had 30 percent of battery life remaining so i pluged it in and let charged for a little bit while it updated my phone and ever thing after it updated i unplug my phone and started playing on my phone to see what ICS was all about but when it got to 15 and said " connect to your changer so i did !!!!! should i haved let my phone going complete dead since i unplug without it fully changer or does it matter ?????????????? if someone could please help me !!!!:)

    What was your battery reading right after the update when you unplugged the phone? I have never let my Maxx drain further than 20% battery ever before I charge it. Yesterday after the update I also played more with the phone trying to learn the OS, as did most everyone on this forum. Give it a few days of your normal use before you decide your battery life has decreased. I took my phone off charger today at noon, it was 100%, and now it's 80%, with about 30 min talk time, and mostly standby. that's about normal batt life for me, maybe a little better than before the update. I'm still going to watch it for a few days before I make a conclusion about battery life.

  • 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'.

  • Diminished battery life since 10.6.5 update

    I updated my computer with the OS X 10.6.5 update when it came out a week or two ago and since the update, my battery life has gotten incredibly short compared to what it used to be. Normally, without having Airport on, just using Microsoft word, I would easily get 7 hours of battery life. Since the update, with 100% battery I'm getting 3.5 hours at the most and it's down to 75% within 20 to 30 minutes. Oh and I've had the computer for about 3 months. Battery health is already down to 92%
    I'm beginning to think I just got a buggy computer because I've been having trackpad issues, and my USB ports don't recognize printers, no matter what I do.
    Any idea's on my battery problem? I have searched and searched the internet and have found nothing so it may be an isolated issue.

    This sounds exactly like what My 13 inch (mid-2010) MBP is doing.
    From day one (about 4 months ago), the battery showed that it was down to 92% with coconut battery? I've never gotten over about 6 hours of battery life; after this latest update to .5, I'm lucky if I get 3.5 hours of battery life.
    I've checked the activity monitor and nothing is running the CPU excessively, except when I'm watching something in flash, but even if I block all flash, I still get the same battery life. Also, it's always warm on the bottom (even with flash blocked) and the fan runs all the time, too.
    I'm not doing anything differently than I did before the update - just have chrome open all the time.
    I swear apple is getting lazy with everything software related lately.

  • HT1414 anyone noticing a decline in battery life after downloading ios7????

    anyone noticing a decline in battery life after downloading ios7?

    I have an iphone 5. Ios 7 is a disaster for battery life! It used to drain about 1% every two hours, 5% over night roughly (not being used). Now it is draining at double the rate. It drained 10% over night and it isn't even doing a thing. I think something is clocking up usage when it's idle.
    Screen brightness is minimal.
    Background app updating is restricted to one app which isn't running the majority of the time.
    Dynamic wall paper and other stupid stuff is all turned off.
    I can't turn off the stupid clock animation. I wonder if working out how that is displayed is the issue???
    It shouldn't be draining at 1% per hour when not even being used.
    Favourite locations is still switched on.
    Is there any benefit in turning off wifi and using 3g data only? I had the issue before that having 3g enabled meant double the battery drain so I only used it when I was out.
    Ipad mini seems fine though. Battery life is same as last ios6 ie about 14-16 hours use.
    I now have caret running to find out what the rogue thing is. The majority of the time few apps are running at all.
    My general average usage is 12-15% per day if lightly used and 25-45% if it is moderately used. Now the phone is draining at 25-33% a day when lightly used!
    Beats me why an ipad mini which is advertised at up to 10 hours on wifi nearly doubles that and the iphone which is advertised at the same rarely reaches it. I usually get 8 hours of active use if I'm lucky. Now it's more like 5-6 which is hopeless.

  • What is going on the my battery life, after installing Mavericks, what a drain!!!

    What is going on the my battery life, after installing Mavericks, what a drain!!!

    You can try resetting the SMC and NVRAM.
    http://support.apple.com/kb/ht1379
    http://support.apple.com/kb/ht3964
    You can also try running the short and/or extended Apple hardware test by holding D button while booting up and then following the instructions.
    http://support.apple.com/kb/ht1509
    If that doesn't work (seems not extremely likely that it will) you can backup and try reinstalling a fresh OS.
    If that still doesn't work maybe the battery is bad.  If you don't feel like messing with all that just take it to Apple.  They should have a test they can perform.

  • Is it normal for iPhone 4S to lose 1% battery life after 2-3 minutes of using?

    Is it normal for iPhone 4S to lose 1% battery life after 2-3 minutes of using? So in 2 hours, 24 minutes usage and 15 hours, 17 minutes  in standby mode, the battery became 68%...

    sounds plausable
    also you can't really 100% trust it's batt% batteries are an analog technology the only thing the iphone can judge how much batt is left is by measuing amp amount the batt is producing and then over time estimating how long before it's zore
    but anyway Its not wise to not put a battery for charge before bed when it's 12%
    if your reason is you think it's good for batteries to be empty before charging then you believe in a myth and in the process damaging the battery in your ios device

  • 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.

  • MBP 13" Aug09, lost 2 hours battery life after upgrading to SL

    Hi, my Macbook Pro bought on Aug 09 lost 2 hours of battery life after an upgrade from Leopard to Snow Leopard.
    I brought it to the Apple service center where they checked the battery and they said that the battery has no problem.
    Then, they suggest me to format my mac and reinstall Snow Leopard on a clean disk which i did without any success.
    So now, my battery still hold 100% of it's original capacity (over 5450mAh) but my battery died before 3 hours with 0 program running !? (it used to last over 5.5 hours while running Leopard)
    What's the matter with my battery.
    And of course, i tried all the calibration before i post this topic.
    If anyone can help now, it would be so great ! can't expect anything from Apple as they consider my battery as new.
    Thanks !

    I too have been experiencing worse battery life.
    I used to have about 3.5 hours on my now one year old Unibody MBP.
    After SL (and switch from original 5400rpm to seagate momentus 7200rpm) I'm now down at about 2 hours.
    Wifi enabled
    Bluetooth enabled
    Brightness around 80%
    2 hours is very little compared to the promised 5 hours.
    My battery stats:
    Health: 94%
    Cycles: 112
    Full charge: 4344mAh
    Feels like I'm on an old lousy PC laptop again.

  • Awful battery life after latest OTA update

    I've owned my Bionic for about 16 months now, and up until recently, have been very pleased.  After the initial Jelly Bean update, I was enjoying the best battery life I had ever experienced, up to 20+ hours with moderate use throughout the day.  However, the latest over the air update (I remember hearing my phone restart itself after the update in the middle of the night), my battery life has suffered dramatically.  At first, I thought the battery was bad, so I ordered a new one, but the problem persisted.  I searched online and discovered others were experiencing similar issues after updates.  I have tried various solutions, included wiping the cache, deleting apps one at a time to determine a culprit, and eventually even a FDR, but none have helped.
    I am almost positive the issue is stemming from "wakelocks" and other things waking my phone up again and again, even with the display off.  My battery will drain from 100% to 40% as I sleep at night, even with WIFI and data disabled.  The battery stats show Android OS and/or Display (they alternate) as the leaders for my battery usage, usually around 40-50%, which is much higher than it used to be.
    I have become increasingly frustrated with this issue, as there seems to be no known solution other than getting a new phone.  I find it almost inexplicable that an update could go out that causes such problems.  My phone has basically been rendered to a tethered device, as I can't go more than 8-10 hours without recharging.  If there are any known solutions, or if I can possibly receive a new Bionic, please let me know.
    Thanks.

    After the Google logo appears and I try to go to step 5, I get the green
    little robot on his back, 'tummy' open with a red triangle and exclamation
    mark in it....and it stays there for a long time???
    Then the phone reboots....problems stay.
    I do not know who you are Kevin but I was at the Verizon store on Friday
    and I was told to call customer service as they are not responsible for the
    software...it's Samsung's problem!?
    I am a +$300 a month client and this is the service I get!
    I will close my account, pay whatever it takes and go someplace else if
    this doesn't get fixed fast...this did not happen on my request and I'm
    stuck with it.
