    Coming from an ANDROID I was curious on how to kill apps to save battery?

    kill? the home button? then I suppose you could "kill" it in the multitasking tray

    Do you mean close apps?

    Double tap home button, press and hold an icon until a cross appears. That closes it.

    iOS multitasking should save battery though, most apps are 'frozen' and use very little resources when not open.

    Hope that is what you were talking about.

    If you used task killers on Android you were doing more harm than good to the battery. iOS like Android will manage apps on it's own. You don't have to "kill" apps.

    double tap the home button. a row will appear underneath the home screen, these will be the all of your open apps.

    long press on any of these apps (while in the multi tasking tray) and press the small X to kill the app.

    iOS is good at doing this when needed and multitasking works differently as not all apps are actually running in the background. A lot are suspended when closed.

    You can kill an app by double clicking home to bring up the multitasking bar then hold an app like you would move it then tap the x.

    You normally shouldn't have to kill apps on either Android or iOS.

    Both OSes keep recently used apps frozen for instant reuse, and that's what you see in their task lists.

    It doesn't mean they're using battery.

    Ok, because for example let's say I open ESPN Scorecenter, and I close it.

    I don't want it to run in the background to kill battery

    If it's well designed it shouldn't be wasting resources int he background, but you can just double tap to bring up the multitasking bar, hold down on the app, then hit the "-" in the corner. This effectively kills the app, but again, it's not something you should have to really worry about.

    It does not run in the background. It is simply saved to RAM when you switch away.

    You know, there is this handy little booklet called the "User Guide" that comes with every iPhone. How about spending a few minutes to read it? Alternately, this forum has a search option!

    Scorecenter, and most all apps, won't affect your battery enough in the background to worry about killing them often. It's not like it's fetching scores all day in the background.

    It's a good thing to be able to have the option to kill apps, but it's rarely beneficial.

    Just to elaborate for the OP...this trick is useful when an app really has gone wacky. I've sometimes had games load weird where something doesn't work (like, no sound or something) and using this trick sets them back to normal.

    But it's only something you need to do when something's gone wrong. It's not an everyday thing.

    The little booklet usually doesn't tell much.

    it's better to direct them to open Safari - then Bookmarks - and the real user guide is linked to there :)

    Uh... actually, Scorecenter can't fetch scores in the background... sorry..

    There are several ways to multi-task in iOS. There are only a couple worth worrying about.


    Local Notifications
    Push Notifications
    Task Completion
    Frozen State

    Let's handle each one by one.

    GPS apps, you can tell these are running by the arrow in the menu bar. No arrow? It's not running in the background.

    Audio apps, you can tell these are running in the background by the play button in the menu bar. No play icon? It's not running in the background.

    VOIP apps, you can tell these are running in the background by the red menu bar. No red menu bar? It's not running in the background.

    Task Completion. This allows apps to "finish" doing some task in the background. They can run at max length for 10 minutes. Then they're killed automatically. You really don't need to worry about these.

    Push Notifications. Same as in previous versions. Internet based notifications.

    Local Notifications. Same as push notifications, except they come from an internal calendar/alarm system. They don't use much battery and thus shouldn't be worried about.

    The final one is frozen state. This is what most apps do. When you close the app it is "frozen" in the state it was just in. It isn't running in the background, it is frozen. When you reload the app it takes you right where you left off. When it is frozen it isn't using any processor power thus isn't an issue for battery life.

    Point is, you don't need to kill tasks. If you see the icons for multi-tasking in the menu bar, by all means kill the task if you're not using it. But otherwise the "multi-tasking" bar is more of a "task menu" that let's you quickly switch applications without finding them on your home screens.

    As others have said, the whole "Task killer" bit is doing more harm than good.

    Try turning down your screen brightness, that helped me the most with my droid.
