SAFARI: running in the background:

When I access a website there is an automatic refresh of the content. When I open a different webpage with Safari, then the automatic refresh on the first page stopps! How can I have a webpage be refreshed in background?
Does Safari download content when it is minimized / not visible?
When I go back to the first page, then the automatic refresh is not there any more. The function has been de-activated by Safari on Ipad. (On a Firefox on windows there is no such problem). How can I get the same webpage behaviour than before. (I know that reloading the page does the job. But this should be automatic and not from the user)

The ipad like a lot of other mobile devices use a type of multitasking that differs from multitasking you would find on Mac OS X, Windows or Linux.  Apple chooses to put most background apps on iOS devices in a suspended mode which allows the application to be paused in the background and then respond quickly when brought to the foreground. Some application functions can continue to run in the background.
Features that are allowed to run in the background are music, location services, airplay, VoIP, push notifications, but it is still up to the developers to make use of this functionality.
I don't believe Safari is one of the applications that will continue to run in the background.
Why does Apple choose to do this? Short answer: Battery life and performance.  If app developers were allowed to choose whether or not to have their application to run in the background, bad programmers would quickly kill the performance and battery on the iOS device.
Some devices such as andriod phones and the blackberry playbook allow broader multi-tasking. The trade off? Andriod phones have task killers, which forces the user to manage their performance and battery life. The playbook comes shipped with a default of using suspended multi-tasking on vs. full multi-tasking - since full multi-tasking would again affect performance and battery life.
I agree it would be nice if webpages continued to load if Safari is in the background, and maybe this will be added / enabled in the future. I think Apples design provides a better user experience and still allows most of the functions to run in the background that need to.  (I don't need a movie to play in the background or game).
My guess would be Safari doesn't allow background use right not because of issues like auto-refresh pages, which again would affect performance and battery.

  • Does Safari use up bandwidth if I leave it running in the background with zero tabs open?  Do I have to quit the application each time I am done to avoid exceeding my internet usage/host quota?

    If I leave Safari running in the background with zero tabs open, does it still use up bandwidth?  Do I have to quit the application each time I am done to avoid exceeding my internet usage/host quota?  I'd rather not have to since quitting the application and restarting it when I need to will quickly become tedious, but if that saves me on bandwidth usage, I'll do it.  Thanks!

  • How to run a safari window in the background at all times?

    Ok, so you are probably wondering why I want to do this. Allow me to explain. The website twitch.tv is a streaming service for gamers, and there is a browser plugin specifically for the site called betterttv.
    One feature of this plugin is that you will get a notification whenever someone you are following starts broadcasting, right in your notification center. But because its a browser plugin, and is specifically for this one website, it requires a safari window to be open with the website twitch.tv in order to push the notifications.
    So my question is... how can I make a browser window stay open at all times and run in the background with this website open so that I get my notifications? I had the idea that I could retain the window even when I "quit" safari, because I can run a seperate instance of it in the form of Webkit Nightly which isnt affected by safari not being running.
    But I am still oblivious as to how I would set up a window like this, and it has to start at login in addition to being running throughout the day. (I shut my Mac off at night.) Any amount of help would be appricated

    I'm well aware of how to minimize thanks, and it *is* possible to have a Safari window open if you quit it, because you can run it as a separate instance by using WebKit Nightly...
    I am just looking for the best way to set it up so that a WebKit Nightly window will open upon startup, navigate to that webpage, and hide itself. Preferably in the background. This could be done using a .command file or a startup script in automator. My question is.. What is the best direction to take?

  • If Safari or internet apps are running in the "background..."

    Are they still going using data? I'm a new member on a 2GB a month plan. Most of the time I'm on wifi, but not always. I've been being careful to turn them off if I'm not on wifi, but how careful do I have to be? I don't really know much about this.
    Btw, what is a quick way to turn my apps off? The double click method on the circle and then hold a button until the minus button comes up and turn them off that way or is there a quicker way?

    Very few apps run in the background - mainly music playing apps and GPS apps.  Double-clicking the Home button gives you a list of previously used apps, not (as so many people believe) "running" apps.  You can delete the apps from the list if you wish, but it will make no difference to energy usage (unless they actually are running, as in the categories above. You should know if you are using GPS or if you can hear music).

  • Apps running in the background

    It seems to be if you have the app linked to a watch complication or you have it on your glances page, then those apps loads much faster.  I figure they are always running so the data can be displayed on the watch face or quickly at a glance.
    So if you have every possible app on your glances page, then your battery life would drain much faster than if you have fewer apps.
    I only have 3-4 apps on my glances page and I can easily get 20 hours of battery life, and this includes a 1 hour workout using GPS and HR monitoring.

    Tbh, the biggest battery drain is your email push settings. I'd look at those before worrying about terminating background apps.
    You can see everything that's running on your phone by using a "process monitor" app. I use one called "iStat". Unfortunately, iStat can only show you what's running, it can;t actually kill anything. It will definitely tell you which of the 1st party programs (browser, email, ipod) are running in the background.
    If you actually want to kill one of these, the procedure is:
    Open the app in question (e.g. launch the ipod app)
    Hold the power/sleep button until the red slider appears.
    Hold the sleep button for around 6 seconds (eventually the red slider will disappear and you will be returned to the home screen).
    Whichever app was running (e.g. ipod) will now be forced to close.
    ** note: To close safari, you can simply close all the "tabs" down, and then exit. If you close safari when there are no tabs in use, it will completely shut down.

  • Kill QuickTime running in the background from my iphone app?

    Is it possible to send a kill or stop or pause quicktime command from within an iphone app? I would like to add a button to kill music playing in the background from streaming radio in safari/quicktime so user does not have to launch safari to stop the background music. Example: if I have a painting app the user can press a button in the app that will stop the music. Thanks.

    If you're talking about closing running apps, they changed it up a bit from iOS6. Now you just double click the home button to bring up the running apps, side scroll to the app you want to close, then just swipe up.

    Unless you are actively accessing the FaceBook app or actively accessing FaceBook via Safari, nothing is being downloaded.
    This applies to iOS 5 as well.

  • Here is How you close out an iPhone app that is running in the background

    How do you close out an iPhone app that is running in the background in the new iOS 4? We’ve had more than one reader ask this question since the launch of the new iPhone operating system, and the iPhone 4, last week. Some have asked about this due to battery drain concerns, and others just because they want to be able to shut down a backgrounded app.
    So this seems as good a time as any to share a quick tip on how you can force apps to close in the new iOS 4.
    There are two ways to fore an app to close down under iOS 4. The first is by doing a ‘force quit’ on the app, just as we have done under the previous version of the iPhone OS. To do this, you press and hold the power button while you are in the app you want to close down. Wait for the ‘Slide to power off’ bar appears across the top of the iPhone – then don’t hit Cancel, but instead just hold down the Home button continuously until the app closes and you drop back to the home screen.
    The much easier method now available in iOS 4 is to use the Multitasking bar to close any app you want. Here’s how:
    – Double tap the Home button to bring up the Multitasking bar
    – Press and hold anywhere on the multitasking bar until the icons on it start to wiggle.
    – While they are wiggling, each icon has a Minus sign symbol above it.
    – Press the Minus symbol above any app to close it down.
    That’s it. This will work for any app you want to close, including the Apple built-in apps like Mail and Safari etc.
    Hope this quick tip is helpful to some of you who are getting to know iOS 4.

    The apps on the bottom are recently accessed apps. Instead of closing when you exit the app they go into a suspended state, and will load faster when you next launch them. Unless they are a streaming app (like Pandora) they do not use any power when they appear in the active app list.
    This information, as well as the OP's post, are in the latest user guide. I guess nobody reads manuals anymore

  • Safari on in the background

    I've noticed that Safari is repeatedly running in the background and doesn't allow us to logout from the account or shutdown without force quitting it, and when you do, you have to be the Administrator.
    What's the reason for this?
    We use Firefox for web browsing, so we hardly ever start Safari for any reason.

    Hi,
    What you can try is to trash the com.apple.Safari.plist
    This is the preferences file for Safari. You can find this file in ... HD>Users>Your_Name>Library>Preferences folder.
    And if this is not solving the problem, that DRAG "_don't trash_" the Cookies.plist to the Desktop ...
    You will find it in ... HD>Users>Your_Name>Librari>Cookies folder>Cookies.plist
    Post back with the results ...

  • When I click on a new link, it opens a whole new firefox instead of using my default which is running in the background

    I have firefox as my default browser. Anytime I click on an email or search for something, instead of opening my default browser, firefox loads a new firefox page. It is a blank page just as if I had never had one. It has nothing on it except how you would start out before you set up your tabs and history etc. My default firefox is still there running in the background but I must click on it and manually put in the link I was trying to open.
    Any suggestions.

    Some added toolbar and anti-virus add-ons are known to cause
    Firefox issues. '''Disable All of them.'''
    Start '''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Firefox in Safe Mode]''' {web Link} by holding down the '''<Shift ''(Mac Options)'' >''' key, and then starting Firefox. Is the problem still there?

  • Can the width of a report that has been run in the background be increased?

    Hello Experts,
    How can I increase the width of a report that I have run in the background so that it does not wrap text to the next line?
    I have been running the same HR report successfully in the background for many months.  Today I ran it with the same parameters that I've always used and when I retrieve it from my Own Job Spool - System | Own Spool Request | Display Contents the last field is wrapped to the next line.
    Thanks.
    Regards,
    Jeanette

    Jeanette,
    Thereu2019s another possibility if Tedu2019s suggestion doesnu2019t work. When you look at your spool requests, thereu2019s an icon on the toolbar next to the eyeglasses that looks like a yellow rectangular callout. Itu2019s called u201CDisplay in Maximum Widthu201D. Select the Spool no. to display and then press this icon. Shift + F4 is the shortcut.
