Phantom Usage When In Standby

I started a thread when the OS was at 2.0 about phantom usage:
http://discussions.apple.com/thread.jspa?messageID=8136179
Thought it would go away in 2.1... but it hasn't:
http://gallery.me.com/wsuschmitt#100019/IMG_0001&bgcolor=black
I believe that the iPhone 3G has a flaw in the OS that doesn't shut off the processor and drains the battery through what I'm calling "phantom usage"; that is, accumulated usage time on the iPhone 3G even when not using it.
I understand a bit of time will be used under "push" conditions, but if you take a look at the screenshot in the gallery link above, you'll see that of the 18 hours of being off the charger, there is 10 to 11 hours of usage. Problem is, 8 of those 18 hours was spent by me sleeping, and another 8 hours was spent at work. I know I'm not using the iPhone while sleeping and I don't have time to use the phone constantly while at work.
So, of the 18 hours of being off the charger, I can probably account for MAYBE 2 hours of use. Where did the other 8 to 9 hours (for a total of 10h 52 min) of usage come from? This phantom usage is killing me, as I have to charge the phone 1-2 times a day to get any real use out of it.
Anyone else still have phantom usage on their phones after upgrading to 2.1?
Anyone know how to kill the phantom usage? Again, there were lots of suggestions in the thread above, but none of them worked for me.
The phantom usage is there even when push is turned off, WiFi is off, there are no additional applications, and the phone is set to auto-lock after 3 minutes.
This is my second iPhone.
The phantom usage seems to disappear after a fresh restore without a backup of the iPhone for about a day, but then the battery life disappears and the phantom usage starts up again after a couple of days.

This reply is from a NEW user that has only had my IP 3G for 3 weeks.
Since we don't have a process explorer, that I know of, to verify this...I read that most of the apps you open continue to run if you hit the home button. The ONLY way to stop the apps from continuing to run is when you quit an app is to hold the home button for up to 10 seconds until the screen goes blank and then release to return to the home page. This will shut down the app completely.
The other option is (and it seems to be true by the response above) is to shut off the device with the power switch to stop all applications and restart. The user I read about says he does it a least once per day.
I would suggest we try both ways to verify the results by
- complete app shut down with the extra long home button hold
- OR shutting off main power once per day
then compare the results.
I know I myself have tried both and they seem to help but I haven't monitored the usage data figures.
I will start to take note of these and see if either option helps.

  • Phantom touches when holding the Helix by the corner

    My Helix seems to register phantom touches when holding it by the corner(Like when you hold the upper side with your thumb and use the other fingers to support the lower body).
    The device registers phantom touches around the left center of the screen, when I'm holding the device like this arond the lower right corner.
    I know it's not the wisest way to hold a tablet, but this does happen quite frequently during the normal usage of the tablet, and I'm quite annoyed about this.
    In addition, my devices seems to register phantom touches when it's docked and is not fully opened.
    I think the flex caused by the force applied to the chassis is the primary cause for this. Are any of you sharing the same experience with me? Or is it just me?

  • Phantom Usage - iPhone Auto Update of Apps - How to turn off?

    Since upgrading to 2.2 the "Usage" of my phone has gone way up. Example, my phone since last charge has been on for 2 day 17 hours 15 minutes. My call time has been 35 minutes, however my usage time has been 2 hours 55 minutes. I talked to Apple and they have had reports on "Phantom" usage. That is Apps and system software not shutting down. All the rep could do was to make me an appointment with the Apple Store 3 hours away.
    Under setting's I have about 10 Apps that are in the "AutoUpdate Settings List". I think this could be the problem. How the heck do I turn this Auto Update Off????
    Thanks

    I've had my phone come back from sleep with the red number around app store when I haven't opened app store lately. I thought that was a normal feature, like mail.
    You mean it should not do that?
    I cannot find any setting which controls it however.
    PS. I have no idea if maybe it is getting that info through itunes sync or wifi or wireless or what -- I just know it mysteriously pops up without me looking.

  • Google Earth Plugin and LabVIEW: High CPU usage when adding placemarks

    Hi,
    I posted this question on stackoverflow earlier this week but feel it might be better suited to the LabVIEW community specifically so I'm reposting here:
    I'm writing an application which uses the Google Earth Plugin to display events on the globe. Each event is a single point kml placemark with an icon which is a 3kb png file. Placemarks are uploaded to the plugin as they are received by the software. I am experiencing increasing CPU usage with the number of placemarks that are added.
    I have tested displaying a new placemark every second and running until the software running the plugin completely froze (graph attached). The GEPlugin (green trace) stopped responding (i.e. the globe did not respond to the mouse) at around 1200 placemarks added and CPU usage was at ~30%. When the software itself (red trace) froze the plugin was using around 50% CPU and ~3700 placemarks had been added). After the freeze, no new placemarks were added which caused the software to respond (but not the plugin) so I could clear all the placemarks. After the placemarks were cleared from the globe, the CPU usage of the plugin returned to around 5% CPU.
    So what I've seen is that GEPlugin CPU usage increases linearly with each kml placemark added. Is this the expected behaviour/ a normal limitation of the plugin? If not is there a more efficient way of adding many placemarks to the globe?
    I am using GEPlugin version 7.1.1.1580 (API version 1.010) and LabVIEW 12.0f3
    Please see the test results attached. Any input greatly appreciated!

    Hello,
    I have had a look at your graphs and understood what you are trying to do. To me it seems that as the image gets more complex it gets harde to render which wold likely cause increase in CPU usage resulting in the freeze. I would suggest you try running the program on anoher computer to check on the RAM front of things. If this is a limitation of the GE Plugin then unfortunately I can not do much to help, but if you think this is a problem coming from your LabVIEW code then you can post your code here and I can take a look.

  • High Virtual memory usage when using Pages 2.0.2

    Hey there,
    I was just wondering whether there had been any other reports of unusually high memory usage when using Pages 2.0.2, specifically Virtual memory. I am running iWork 06 on the Mac listed below and Pages has been running really slowly recently. I checked the Activity Monitor and Pages is using hardly any Physical memory but loads of Virtual memory (so much so that the Page outs are almost as high as the Page ins (roughly 51500 page ins / 51000 page outs).
    Any known problems, solutions or comments for this problem? Thanks in advance

    I don't know if this is specifically what you're seeing, but all Cocoa applications, such as Pages, have an effectively infinite Undo. If you have any document that you've been working on for a long time without closing, that could be responsible for a large amount of memory usage.
    While it's good practice to save on a regular basis, if you're making large amounts of changes it's also a good idea to close and reopen your document every once in awhile, simply to clear the undo. I've heard of some people seeing sluggish behavior after working on a document for several days, which cleared up when the document was closed and reopened.

  • How can you manage data usage when cellular data is off, but you are using WiFi where your WiFi provider charges for data use?

    I spend quite a few months each year in Canada where I use a Telus Cellular Hub device which is also my WiFi Router.  My iPhone 5 has Cellular Data set to "Off" which insures I won't be charged via my Verizon Wireless Service Provider for charges while in Canada.  Trouble is Telus, Rogers and all the Canadian Internet Providers charge for all Data going through their Systems.  Again, My Cellular Data on the iPhone 5 is turned off, but I use WiFi for such things as checking the Weather, or FaceBook, or searching the Web. 
    I believe that things may be happening in the background from various Apps that use quite a lot of Data.  It could be that iCloud is part of the issue with things being backed up automatically.  It also could be that Apps like AP or other News Apps are sending large amounts of Data in the photos associated with their New Stories, etc.  I typically turn off the App Store "Updates" such that they don't automatically load.  The FaceBook works now posted videos play when you are just scrolling through the News Feed. 
    I have been trying to fine an article somewhere which focuses on this specific problem but unfortunately many if not most articles are about folks worried about using Cellular Data while in a WiFi environment when their Cellular Data is turned on. 
    Does anyone know of a fairly comprehensive article about what settings on which Apps might reduce the Data Usage when Cellular Data is turned "Off" but you are going through a Service Provider who charges for all Data Accessed even when you are using WiFi?

    Thanks for your comments, it is clear you understand my plight.  The trouble is fully understanding what Apps and App Features are transferring data in the background any time you happen to turn WiFi to on (even if you have had it off most of the day or night).  Obviously things like Location Services can constantly be sending and receiving data from my iPhone without any action on my part.  Also if you have things like photo backup on the iCloud then each time you take a photo you are sending a copy out.  All App Updates if set to Automatic also can add up to quite a bit of Data.  Reading the News on AP or scrolling through FB News Feed is actually adding up to a lot of Data.  There could be other culprits that I am not even thinking of.  I don't want to turn Apps like Find My Phone off or turn iCloud off due to loosing the value of such a program entirely.  Again thanks for your quick response. 

  • High CPU usage when graphics card is put at work

    I have a 13inch Air with 2GB RAM and 256GB  with Windows 7 Ultimate 64bit. All possible updates have been installed.
    I noticed some tearing when trying to move program windows across the screen so I started checking the CPU usage. I saw that it is spiking to 25-35% when moving a window across the screen.When you drag down a window you can see the different copies of the top bar across the screen. Not smooth at all like on a standard PC windows system. Same issue when scrolling through webpages which spikes the cpu
    I also noticed a high cpu usage when playing mkv files 25-30% while on an Atom HTPC i get a lower load playing the same file. The Air should be faster than an atom with a nvidia 9400m when playing video files.
    I already tried updating the nvidia files to the latest version on their site by hacking the driver inf but this did not resolve the issue.
    Has anyone experienced the same or know what could be causing the beavior?
    Many thanks

    Maybe my initial post was not clear so let me add some clarifications.
    I have the problem with Aero disabled
    I have the problem on the Apple site which does not have any flash content.
    I have already hacked the lastest nvidia drivers to get them on my system which did not change anything. Can you provide a link to some other 'supported' beta drivers?
    I am using the new 13 inch air so it has the newer graphics card so I would expect it to be faster than an old HTPC with a 9400m in it. I wasn't stating that my Air had a 9400m.
    It would be great if someone you also do the test to check the cpu load:
    - when playing a 720 mkv
    - when dragging a window across the screen
    Just open task manager and see if the CPU spikes.
    Many thanks!

  • My company loaded profiles onto my iPad for email and calendars.. There is also a signing certificate and a certificate. What are these for? Additionally are they able to monitor apps and usage, ie Internet usage when it is not on their wifi?

    Do you happen to have an Android?  If so and depending on what version there is a great data usage analyse tool built-in.  See if you can go to Settings -> Data Usage  from there you can pick a current or previous billing cycle and then use the vertical sliders to select a date range and it will filter the usage data per app to show you exactly what app(s) were using data during that time frame.

  • Ipod touch won't ring receiving FaceTime call when in standby

    I am trying to FaceTime one touch from another. If the one receiving the 'call' is in standby it will not ring. If I take it out of standby or disable locking then it rings normally. I am assuming this is because it loses the wifi connection when sleeping? Is there a way to keep it connected? Is there a way to receive FaceTime calls when in standby mode?

    Welcome to Discussions, mjl4321
    My iPod touch rings and displays the incoming FaceTime screen from sleep. Yours should, too.
    Here are some things you can consider:
    • If you are using both on the same LAN, try moving one to another wi-fi location. Some users report problems when using more than one FaceTime device simultaneously on the same LAN.
    • If you have multiple devices on your network, check with your ISP for this possibility:
        http://support.apple.com/kb/HT2460
    • Might you merely not be hearing the call? I changed my ringtone to a louder sound and turned the ringer volume to maximum so my partially deaf ears could hear the call if I happened not to be looking directly at my iPod when a FaceTime request was received.
    • Do you have a solid wi-fi connection with minimal interference? I occasionally need to refresh my wi-fi connection. In my case, I think this is due to interference from my nearby neighbors, but interference can be caused by portable phones, microwave ovens, and a variety of other electrical sources:
        http://support.apple.com/kb/HT1365
    To refresh, turn Settings > Airplane Mode ON and then immediately back OFF.
    Of course, if you lose wi-fi while your iPod is sleeping, you will not know when you need to reset. However, if connected apps ever stop working while you are using them, this may be your problem during sleep, too. You can try the suggestions in the link above to see if you can eliminate the problem.
    • If nothing works for you, ask your retailer or Apple Authorized Service Provider to check whether your iPod may need service.
    BTW, your posted system info shows "new ipod touch  iOS 4". If this is correct, you should update to iOS 4.1. If it is wrong, you can correct the info in the "My Settings" link in the upper right part of the page whenever you are logged into Discussions.

  • Reduce CPU Usage when Runnig Telnet on Win2000

    Does any one knows how to reduce CPU usage when iam running my telnet developed using java classes.Every time when i start Telnet CPU usage is shooting to 100%.Can any one help to me solve my problem.

    You are probably doing some kind of loop that is eating all the CPU idle time. You could reduce your use of the CPU by calling Thread.yield() when you do not need to do anything for a bit, or even better, Thread.sleep(...) to pause your program for a specified number of milliseconds.
    Hope this helps some.

    there just have ONLY ONE CORE %sys 100
    the top command show average of all cpu core sys% usage
    when the one core sys% is 100%
    the system are very slow .
    e.g: when I create a database instance used for a long time . over 2 hours
    but generally it will be done at most 1 hours or shorteris any type of OS virtualization involved in this environment?

  • Appying patches when Physical standby in place.

    Kindly suggest steps for patch application /application upgradation. We dont have any replication tool.What is the standard process to sync standby after patch upgradation . Is there any alternative of rsync/rdist utility.
    Is it possible that after applying patch in Primary, On Standby we have to apply as it is, with no Database inclusion as the standby database will be in mount state and will not available for making database changes.
    How to find which files to be copied manually to sync the standby with Primary. Will this method reliable?
    Apologies to ask many questions but i found no single document covering this detailed process.

    Both the links are for applying patches/upgrades for Oracle Database. Apologies i didn't clarify the requirement. It's for EBS R12. So i need to sync the apps tier with primary when physical standby in place.
    Kindly validate below procedure with rsync utility
    After running the Middle Tier and Database Pre-clone.
    To synchronize Synchronize the Appropriate File Systems to Standby,
    rsync –av <$APPL_TOP> <standby_host>:<$APPL_TOP>
    --rsync-path=/usr/local/bin/rsync
    /usr/local/bin/rsync –av <$COMMON_TOP> <standby_host>:<$COMMON_TOP>
    /usr/local/bin/rsync –av <$ web ORACLE HOMEs (10.1.2)> <standby_host>:<$ web ORACLE HOMEs (10.1.2)>
    /usr/local/bin/rsync –av <$TOOL(10.1.3)> <standby_host>:<$COMMON_TOP>
    Synchronize the database tier file system including <RDBMS ORACLE_HOME>/appsutil directory.
    /usr/local/bin/rsync –av <RDBMS ORACLE_HOME>/appsutil <standby_host>:<RDBMS ORACLE_HOME>/appsutil
    Reconfigure the Standby Middle Tier File Systems
    When the file system synchronization is complete, reconfigure the standby file systems. Log onto each of the standby middle tier systems as the APPLMGR user and execute the following commands:
    cd <COMMON_TOP>/clone/bin
    perl adcfgclone.pl atTechStack <INST_TOP>/appl/admin/<Standby CONTEXT_NAME>.xml
    To complete the configuration of environment run AutoConfig using the following commands:
    cd <APPL_TOP>/ad/12.0.0/bin
    adconfig.sh contextfile=<INST_TOP>/appl/admin/<standby context>.xml run=INSTE8
    AutoConfig will report errors regarding to database connection, these errors can be ignored as the database is unavailable.
    Step 4.4.11 - Reconfigure the Standby Database File Systems
    If you had to synchronize the apps utilities on the database server in the prior step, you should also reconfigure the database server. As the ORACLE user on each database node of standby database tier, first stop the listener if it is running, then execute the following commands:
    cd <RDBMS ORACLE_HOME>/appsutil/clone/bin
    perl adcfgclone.pl dbTechStack <RDBMS ORACLE_HOME>/appsutil/<Standby CONTEXT_NAME>.xml
