Excess Battery usage Running Windows xp

I recently installed windows xp using boot camp and noticed right away that battery usage increased by about 10% compared to running OS 10.5. I have applied all updated and firmware releases,has anyone else seen this and can it be adjusted or controlled in some way???
Regards
Brian

Mac OS is written to optimize battery use. Wind'oh!s is not. This is well-known and unlikely to change.

  • Best battery usage for windows

    I use boot camp and installed windows 7 and it's running great, however the battery performance is really not that good (I just got my MBP last month).
    Now I'm wondering, instead of using boot camp and have about 1.5 to 2 hours of windows 7, should I install fusion (or parallel) and get windows 7 to run that way so my battery can run longer?
    any suggestions/thoughts? thanks!

    thanks, Jason for the reply.
    Since I'm still new to mac, I'm still experiencing how to get close to 10 hours of battery life apple claimed. (I tried lowing the brightness, anything else?)
    battery life in windows is no more than 2 hours in windows. I didn't mean to compare the battery life with win 7 and Mac OS X, but maybe you guys who has more experience can tell me which would you prefer:
    1. install windows 7 with boot camp (dual boot)
    or
    2. install windows 7 using VMWare (or Parallel)
    which of the 2 above will have better performance?
    which of the 2 above will have better battery life?
    thanks!

  • Excessive battery usage since IOS 8 update

    Help!!!
    I've a iphone 4s & have recently completed the IOS 8 update on my handset
    Ever since completing this, my battery 'usage' has been excessive & my phone never lasts more than 7-8 hrs even though for the majority of this time, the handset is locked & in my pocket at work!!!
    Prior to this update, I'd return home from work with at least 30-40% battery life but now the handsets died before I finish my shift!!!! Frustrating is an understatement.....
    Another example is after charging fully this morning, my handset says its been on standby for 2hrs 5 mins yet has been used for 1 hr 45 mins..... I've been asleep for most of this time so how does that work?!?!
    Please can you provide me with an idiots guide to reducing this ridiculous level of 'usage'
    Many thanks for your help in advance
    Bret

    my phone not working properly after updating to that too ,is there any way to get back to ios 7 ???

  • Battery life running Windows 7 under Bootcamp/Parallels 9

    I'm contemplating buying one of the new 15" MacBook pros, the fully loaded one with the built in Nvidia graphics, and will want to put windows 7 on it. Assuming I can get bootcamp to work (seems like quite a few people are having issues right now!), I like the idea of doing so, and then accessing it through parallels 9 most of the time. However, it seems that the windows drivers only have access to the Nvidia graphics, and cannot switch to the intel graphics when the extra processing isn't needed, so when running in bootcamp mode, the battery life will suck. Will the same be true in Parallels, or given that this is emulating windows through Mavericks, will it get the full Mac control, allowing it to select intel/Nvidia graphics as it needs.
    Anyone else tried this who can give me some numbers on what the battery life is likely to be in both modes?
    Thanks,
    Nick

    parallel is a virtuel machine and don't have direct contact with the hardware with real drivers
    it access osx generic drivers it will use the generic virtual machine driver osx provide and it will 100% be up to osx how much battery is used
    the no direct hardware assess is also why you can't play games in the virutal machine as it don't use the video card at all

  • Battery life in windows 8

    There have been many questions posted recently regarding a noticeable change in battery life after installing/upgrading Windows 8.  I would like to provide some tips which may help you extend the life of your battery. 
    1.  Ensure that your battery is properly calibrated.
    To begin you should make sure your battery is properly calibrated.  This makes sure that the battery is able to determine the correct points which represent 0% charge and 100% charge.  This is a good step to take as it, along with the battery check, will rule out most hardware issues.  This document will walk you through a manual battery calibration.  The next step is to test the battery, which requires HP Support Assistant.
    2.  Use HP’s Battery Check to ensure your battery is in proper working condition.
    After you know that the battery is calibrated it is a good idea to ensure there are no other problems with the battery by running a battery check.  This is a feature included in HP Support Assistant.  Visit this site to download the notebook version of HP Support Assistant.  After installing this software select the “Troubleshoot” section and then “Power, Thermal, and Mechanical.”  The battery check is located there.  Here is more information on HP Battery Check.
    If the battery passes this check move on to step 3.
    3.  Use HP Support Assistant to download all the needed software for your machine.
    The most common cause of the change in battery life is going to be that all of the drivers, software, and other utilities which HP and the hardware manufacturers use to maximize battery life are missing.  HP is currently expecting to support most notebooks which were purchased after October 1, 2011.  This site can tell you if your notebook has been tested with Windows 8 by HP.  However, not all of the utilities and drivers have been released.  If HP Support Assistant is unable to locate some of the software you will want to keep a close eye on support assistant for updates as well as your product's page on HP’s Technical Support Site.
    Once you have installed the suggested updates, make sure to reboot the PC.
    4.  Ensure that you have all of the Windows Updates.
    Windows 8 has only been out for a week so it is likely you will see updates come out soon.  Make sure you have Windows Update properly configured and that you currently have all updates.  Here is a great article on About.com which covers how to check your Windows Update settings.
    5.  Use Windows to optimize battery usage. 
    Windows has a very feature rich system which allows you to control how power is consumed by the notebook.  From either the Desktop view or Metro use the key combination Windows+X and select “Power Options.”  This will open the Power Plan window.  I suggest using the “Power Saver” power plan.  However, if you’d like you are able to create your own power plan.   Use the “change advanced power settings” option to customize it for your purposes.  Here is more information from Microsoft on saving battery power.

  • I bought my 15" macbook pro i7 just a year ago and my battery life runs out extremely quick..at fully charged it says I only have 2:27 of usage time. I didn't pay for that-what can I do about it? I do have Apple care. Thanks.

    I bought my 15" macbook pro just a year ago and my battery life runs out extremely quickly. This started maybe a month or two ago. Its hard to tell. I only noticed the rapid change recently. Fully charged it says I have 2:27 (2 hours and 27 minutes) of usage time...with about 50% screen and keyboard brightness.
    I've checked inside system preferences and its cycle count is 261 and full charging cap is 6316.
    I have apple care...is this something i can/need to take up with apple. You'd think if you pay the price for these machines you should get mroe use out of them.
    ONLY A YEAR I'VE HAD THIS!
    My PC lasted 4 years before the battery showed signs this dramatic of wear.
    Any help is appreciated, im  new mac owner. thanks.

    do you have a mbp with dual video cards? running the system with the higher end card increases the heat and also drains batt power.
    i have the 1st gen unibody (2008) with an original removable battery of 311 cycles and 4453 charge. under normal use ill be happy to get 1.5hrs. the mac battery counter thing says i have 3.3hrs though (whatever). compared to me, i think you use your battery more than i do, perhaps its the reason why it degraded so fast in a year?

  • My iPad is a few years old but my battery is running down very quickly even when not in use? I have about 16% usage still available !

    My iPad is a few years old but the battery is running down very quickly, is there anything I can do ?

    Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
    How to Calibrate Your Mac, iPhone, or iPad Battery

    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

  • Problem with battery when using windows 7

    I have a new 13" mac book pro. I install windows 7 and used autocad 2010 on windows. My battery usage is very high and i lost all my power in 2:15 hr. Is there anything wrong or if i uninstall the windows 7 again my mac has a good battery life.

    The best of course would be to shutdown Parallels when you do not need it or use the feature called Standby to start at the same point where to stopped when Windows is started again in Parallels.
    What I usually do is to have my laptop running on power as long as I am sitting on my desk during the day. Only when I am in meetings or work from my home office, I let it run on battery so that it gets de-charged from time to time to save some battery life.

  • IPad iOS 6.1.2 update causing excessive battery drain

    I have noticed in other discussions that a number of iPhone users have experienced excessive battery drain after updating to iOS 6.1.2.
    I am now experiencing this problem in a big way after updating to iOS 6.1.2 on an iPad 3.   Prior to this update, my battery life was very good, dropping to only 70% to 80% at the end of a typical day of use.
    After the update, which was said to be to fix a previious Mail Exchange battery drain issue (one that I was not experiencing), my battery was dropping to 30% after a few hours.   It was literally like holding a bucket with a hole in the bottom and watching the water drain out.
    I noticed that my Usage time and Standby time were identical, even though the ipad had been in sleep mode much of the time.   This indicates to me that something about this patch is causing the iPad not to actually sleep when in sleep mode.
    The iPhone discussion forums point to a number of possible fixes, including uninstalling all emails and re-installing them all the way to a total erasure and reinstalation of everything.  This worked for some, but not for all victims of this problem.
    Until Apple recognizes this problem and sends out another update, one less painful solution that worked for me was to change all of my email accounts from Push to Fetch every 15 minutes.   This has stopped the problem for me, for now. so I wanted to share this in case anyone else is experiencing similar problems.
    If other community members have discovered other short term or long term fixes then please do post here.
    Apple, I await an update that will allow me to restore Push functionality, or instructions on what steps will work to properly restore full functionality (what to remove and reinstall etc).

    Just to confirm that I have the same problem.  I updated to iOS6.1.2 on Friday 1 March 2013, I have an iPad2.  And Saturday morning my iPad was 0% after having nodded off on a 78% full battery.  This has NEVER happened before, and has become a daily occurrence.  I have now amended my Mail to fetch and hope it works.

  • How can I reduce excessive data usage?

    My wife and I recently moved to the country and have no internet available by a physical cable or wire from an ISP.    Our internet service is provided through a Verizon Jetpack that we lease from Verizon.    We have an iPhone 4s, iPhone 5s, an iPad 1, and an iPad 2 (both iPads are WiFi only) 
    Our problem is excessive data usage.  Prior to our move, our iPhones each used approx .2GB per month.   16 days into our current billing month, the iPhones have each used approx 1.2GB, but our Jetpack (which creates our home WiFi for our iPads) has already used 10GB.  We do not stream anything on our iPads.  We use them in the evening for surfing the internet, checking Facebook, and playing Words With Friends.  That's about it. The Verizon online data calculator indicates we shoud be using about 4GB per month based on our iPad usage.   Yet my data usage log says that one night this week between 7:30 PM and 11:30 PM, our Jetpack used a full 1GB.  Is it possible that our Jetpack is simply "burning up" GBs while we sleep?  

    On my iPhone 4 running iOS 6,  Settings > General > Usage quotes the installed size of the apps not the data usage. I've just installed the Onavo Count which claims to record data usage of each app so one can see which the greedy ones are.

  • Ntoskrnl.exe System %100 disk usage with windows 8.1. all the time!.

    hello i am also having the %100 disk usage problem and am starting a thread to upload my etl. file and see if i can get a solution. thnx. i should also mention i have tried every suggestion i have read on the internet even ones that worked for other people
    did not work for me i.e. (switching to high performance power plan, disabling cd drive, etc.) no matter what i try "system" is always utilizing 90%-100% of my hard drive and it is driving me crazy.
    i can barely do anything on computer without it taking 10x times longer than it should. ive also run dskchk and boot time virus scans and malware scans. all to no avail. i have more than enough ram and a quad core cpu. when i first purchased my laptop it
    was running windows 8 and was lightning fast once i upgraded to 8.1 i think is when the issue started occurring.
    i am currently installing the windows assessment and deployment kit right now and will upload my etl. file to the skydrive asap.

  • Another computer of mine is running windows 7 64 bit and it shows 4 different realplayer or derivative of realplayer plug-ins which seems fishy to me. Are there that many availabe?

    The hp laptop running windows 7 seems to me to be running very strange and many programs have appeared that I did not download as if someone else is actually using it as a server. I am constantly changing passwords, updating plug-ins, software, using a wired ethernet linksys router wrt54g for my lan and still have problems with settings getting changed, programs not working , developer programs appearing, having to reboot, ad infinitum and now I am looking at my Firefox Plug-Ins and see RealJukebox NS, RealNetworks RealPlayer Chrome Background Extension, RealPlayer G2 LiveConnect-Enabled, RealPlayer Browser Record, and RealPlayer HTML5VideoShim not to mention the non-RealPlayer Plug-Ins. My question is do all of these exist and why would I have them when I did not install them. Also, would I need them for Windows 7 64 bit. Any information provided will be most appreciated. I'm about to quit and look for another hobby.

    Hi,
    Have you tried ping ip address of printer? and check if there exists any data lost in network connection. If your network connection is crowded, it can cause delay for printer.
    Also, please attempt to disable all security software temporarily, such as antivirus, firewalls,etc and
    clear all printer cache.
    Locate to task manager, check the state of spoolsv.exe, including cpu and memory. If it has high cpu or memory usage, it may be caused by malware. Thus, you'd better to make a full scan with the latest anti-virus.

  • 10.9.4 excessive CPU usage

    And now a strange case...
    Installed 10.9.4 but it became unusable because of excessive CPU usage. Reverted back to 10.9.3 but now the problem persists!
    Basically, if connect the Ethernet cable the CPU increases and temp raises from 45C to 95C. As soon as I remove the Ethernet cable and stay on WiFi things go back to normal. I already have done the most obvious, i.e. reinstalling the OS from time machine, removing launch daemons and plug-ins, and fixing disk permissions. Check the details below. Any idea? It would be much appreciated. I'm getting nuts with this.

    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Please take this step regardless of the results of Step 1.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • IOS 8.0.2 Excessive Cellular Usage

    For 10 years my average cellular data usage per month has been around 250-350MB. Since updating to IOS 8, my cellular usage has gone up to between 1GB and 1.5GB. My daily usage is now in excess of 50MB for which I cannot explain since I disabled almost ALL services from using cellular. With the exception of find my phone and email I do not use iCloud. The applications I use have not changed in the past 3 months. I have checked the cellular data usage page on my phone and although the total amount of cellular data goes up, the amount listed by service only adds up to approximately 10% of the total. I have noted that even over night while on Wifi my cellular usage goes up.
    I have done a full device reset with a restore from backup with no effect.
    From what I can see from using Techet's "Network Analyzer" and "Status" , apple is maintaining at least two cellular connections to siri.apple.com. With the exception of Siri I don't see any other cellular connections being maintained although I noted that a reboot uses up to 7 MB of cellular data.
    With the exception of turning off siri for 24 hours I'm at a loss as to what else to do to isolate my excessive cellular usage. I should also point out that at this point my guess is that this excessive cellular usage is whats draining my battery as well. Prior to IOS 8 I got two full days on a charge, now I get about 10 hours.
    I will update this article once I have tested the siri theory.

    I have been having the same problem. I average about 100MB of use a day. After switching to iPhone 6/iOS 8, my data usage shot up to 400MB per day.
    From the iPhone's data usage tracking function, I realised that the excess data was being consumed by "System Services --> Documents & Sync", and not by any app. Chunks of around 300 MB were being used every day.
    Similar to you, my data also goes up even while at home, asleep, and connected to wifi.
    I have turned off every option that allows me to block or reduce usage of cellular data, including auto-updates, iTunes Match, background refresh, location services, etc.
    I've turned off syncing wherever available, as I back up via iTunes anyway.
    My Siri is switched off as well. But the problem still persists.
    I've called Apple and they don't have a solution for this. They can only suggest restoring from a backup to see if it works. If it doesn't, they suggest restoring as a new phone.
    Apple also refuses to intervene or assist in any way with the excessive data charges, even though I have pointed out repeatedly that the problems only began when I upgraded to iPhone 6/iOS 8.
    In the meantime, my data usage is going through the roof and my service provider refuses to waive any of the charges. It is extremely frustrating and I really am at a complete loss as to what to do.
