Close all the open Application in one-shot ?
Is there are any way to close all the open application in one shot in ipad rather than double-click the home button and close the apps one by one.

No. You can only close apps one at a time. Most of the apps in the task bar are not actually running anyway. They reside in the task bar there for quick access.
Why do you believe that doing this would be useful?
Restarting the iPad (pressing the home and power buttons until the screen goes black and the Apple icon appears) is the closest you can come. It should shut down any "background" apps or any that are in a frozen state.
Will the battery is not used when all the open apps is in wait state in task bar.
All the open apps killing my battery i am running out of battery life if i doing something important.
So i thought that close all the apps in one shot get increase by battery life for a while.
I thought it was something like that. Note that apps "running" in the background are not actually doing anything, with a few rare exceptions. Some of them aren't even still running. Closing them all is not likely to help.
There is a neat app called "Process Killer" that allows you to close all unused processes in one step. It closes all apps except MobileMe and the app itself (of course...).
It frees up a lot of memory when I use it, so it appears that apps open in the background actually takes up some valuable memory. I don't know if it affects the power consumption though...
Thanks let me try it.
Do you mean this? The product description does not say that it kills processes - it shows you what background are open and (in it's own words) "'kills' with it's simplicity." The 1-star reviews make it pretty clear that it does not kill open apps.
Not only does it not kill processes, but the developer doesn't know the difference between it's and its. 😁
Read the product description very carefully before you try it, as well as the reviews.
PogoPossum,
I don't know what the reviews are based on or how valid they are. I used the app and I have no problems with it. It frees up a lot of memory, which is what it claims to do.
If I look at memory usage before and after I let the app "kill" processes (or whatever it really does) I see a huge difference and I also note that both my iPad and iPhone works faster afterwards.
One review says that apps are still visible as "running" and possible to swap to by double-clicking the start button... but does that really indicate that the processes are still running or that does it simply provide you with a shortcut to start the app again? I don't know.
All I know is that memeory is freed up and that's what I wanted... Memory freed up indicates that less processes are running, I don't have any other explanation.
As I said to iVino earlier, why do you believe this to be useful? Apps running in the background are not actually running in the same sense as in a true multitasking OS (which iOS is not). They are not using any processor time or battery power, with a few specific exceptions. (For example, location services can be active in the background.)
Similarly, iOS does not need you to manage memory. When memory is full and more is needed, an inactive app is closed to free that memory. Closing apps manually to free memory will not hurt anything, but it's also unnecessary.
I never close any of my apps, except for my GPS software, and I don't have speed problems, memory problems or battery problems. This has been personally observed by me with first and second generation iPod Touches, an iPhone 4 and an iPad 2.
In principle, I agree with you...
But it appears that reality is not perfect. I observed on iPhone 3 that memory could be pretty clogged from time to time and I needed to restart it to free up memory and get it back to original speed again. It all depends on which apps you are running. Some appears to eat more memory than others. On iPhone 4, it appears to be less of a problem and I have seen that later iOS releases also makes this less of a problem. I only have a first generation iPad, but I have seen that later iOS releases have improved memory handling significantly there as well. However, it appears to be a good idea to reboot the device after a week or two just to flush the memory. I can't prove this theory scientifically, but I do see a difference in memory usage when doing this.
The reason I actually tried "Process Killer" was a tip that it addressed the problems many of us encountered with the first iOS 5 release: frequent crashes and slow performance. After the pretty quickly released iOS 5 update, that wes pretty much solved, but occasionally killing processes actually helped me at that point, It made both my devices more stable.
The original question was about battery performance, there I don't think that the amount of processes running is the key. A much better way of getting more out of your battery is shutting off location services in apps where they are not really needed. I would guess that turning off push notofications for as many apps as possible helps as well.
Also, turn off the Personal Hotspot on iPhone when it's not needed!
The product description says that it views processes, not that it kills them - letting an external app close other apps would be impossible in the sandbox system of iOS. I don't even think it could really tell you what processes are running , as I understand how iOS works.
I agree with you. It would be nice to have one app to close all open ones. I'm having battery issues and consulted with an Apple salesman and the first thing he checked was the open apps. He told me that they were battery users and to keep them closed.
