    As I understand, once you have opened an app it stays open in the background consuming some power. If you double-click the bottom button, all open apps appear so you can see them by swiping. If you press and hold one then a red close button appears, and the apps can be closed one by one.
    This is a bit tedious. Is there another method to close selected apps, or even a 'task killer' app as there is in Android?

    I open the little task thing and get them wiggling, then just tap all the X's, it's pretty quick for me but I only have a handful of apps that I use.

    However them running in the background does not consume additional resources, because they're not running, they have a 'save state' which is merely a few kilobytes specifying where you were and what you were doing.

    You understand partly wrong. Unless the app has a specific background task, like music or GPS, it is frozen in RAM and consumes almost no power or cpu. The OS will generally remove the app from RAM if the system is running low. Occasionally it is helpful to remove the first few apps in the multitask bar to free up RAM before launching a RAM hungry app. All but last few apps have long ago been removed, and simply have their run state stored for reloading. Most of the time it makes no difference at all.

    When I go through the admittedly tedious process of removing all the apps in the multi-task bar it's all about aesthetics. There is no built in way to remove all the apps at once, thought eh Jailbreak community may have a solution.

    If you are willing to jailbreak there is a very nice SBSettings toggle to close all background apps with one button press. It is called "RemoveBG".

    There is also another one that requires a jailbreak. It's called MultiCleaner.

    I had a problem with this one, though: when I started up the ipad from being powered off, my wallpaper was reduced in size and in the upper left corner, the icons were spread apart and missing from the dock. Respringing solved that, but it was a nuisance.

    Thanks for the explanation, i guess there is no way of quantifying 'almost no power' when to my dismay I have found over 20 apps featuring in the multiple-task bar. I only raised my concern as I am relatively new to Apple, and on my Android phone it is evidently enough of a problem to have several very effective (and free) apps to shut down all selected apps, which can stay selected for each use.
    In the absence of an App Store approved app for this purpose can we infer that as you have indicated, it is not really necessary except for aesthetic reasons?

    Really no reason to bother killing apps most of the time. Go visit an Apple store and check out one of the demo units. Performance is excellent and they have tons of backgrounded apps running from people trying them out all day.

    Slightly off topic: If you are running Android 2.2 or higher, you should check out the discussions on Task Killers. You may be hurting yourself there too. Rather than go any further off topic, just ask and I'll send you a personal message with a couple links to look over.

    Task Killers

    I am unable to pm you because of the 6 post qualification. Sorry it is off topic but just wanted to send this:

    Thanks for your note about the Android Task Killers. I have read those threads on the Android and HTC Forums (Fora?), and have to say that I don't agree with the gainsayers from personal experience.
    Once I had installed Advanced Task Killer on my HTC, I found that I had the perception that the battery life was distinctly improved. Nothing scientific about my test, but I have been using it for about 8 months, and have no problem with continuing as the updates are improving.
    A free iPad Task Killer would be welcome - even if only for aesthetic reasons!!:D

    this scenario has been around before, I have a nokia s60 touchscreen that doesnt close the apps and has a similar "show all along the bottom and then hold each one to close blah blah takes forever so you dont bother and leave the internet running in the background and 3 hours later you have no battery..."

    anyway point is that most of the apps for nokia have an option to 'exit' the app in the menu, why dont apple developers put this in the apps?

    For 99c you can buy XSysInfo which will free up memory before you run a memory intensive app. Can't be bothered to tap on all those wriggly icons.

    If you've been using the iPad for a while free memory can drop as low as 7mb. No wonder safari has to reload pages....

    About a month ago my iPad wouldn't turn on. It was dead even though it had a full battery charge and had been running fine minutes before. I was 5-minutes from an Apple Store so I took it in thinking I had a repair issue.

    After checking a few things the tech did some kind of hard restart by holding down both physical buttons. After a while the iPad fired up again. He said it was a RAM problem caused by too many apps in the freeze state. He said each one locked out a small amount of RAM so it could open more quickly.

    He showed me how to close them down every so often, and do a restart to make sure all the RAM is recovered. I was told it was a common issue due to the small amount of RAM in the iPad 1.

    Remember the ram is shared with the graphics chip so you'll never see more than 130mb free at it's cleanest.......

    I have not yet found out how to 'see' the available RAM. Grateful if you would enlighten me.

    This is the app I was looking for! I went for it, - not 99 cents for us privileged Brits, it cost £1.19 (which is $1.91), but from showing 6.6 Mb free memory, I cleaned and it jumped to 53 Mb.
    Just have to see if there are any adverse side effects now.

    It's interesting that I didn't even realize how horrible the multi-tasking feature is on the iPad until a few weeks ago. I would play games and use apps like normal without closing them down. Eventually (after having about 20-30 open simultaneously) I noticed my battery would drain faster than I could blink. We're talking 5-6 hours instead of 10-12 hours. After closing down all of the apps that were open, I was able to get MUCH better battery life.

    It may freeze the state of the app, but running all of the apps in the background kills the battery like crazy over time. Apple should really implement some sort of "Kill All Apps" feature, so I don't have to painfully close each one.

    The way I know how to do this is: jailbreak. In Cydia, install SBSettings. Within that, go to this screen:



    Turn on Statusbar Free Mem (and date if desired).

    You will then see this at the top of your screen:

    mem1.jpg

    If that last pic is not readable on here, it shows the date, time, and free memory in the top center.

    Jailbreak is definitely not for me. The point is, as Nemesis stressed, that Apple should have built a task killer into the system when multi task was introduced.
    Interesting how this thread has developed from assertions that the open apps use little power, to confirmation as I thought that keeping them open is a cumulative drain. Use of XSysInfo has definitely confirmed this for me as I have seen it drop as low as 3.9Mb and then up to 93 Mb when I clean up.
