Your logic has a big gap. Apps use power when they take up CPU time (are running). Just because they are in RAM means little. Most apps are frozen when in RAM and make no significant difference in power drain. There are exceptions, like GPS, music, downloads, and a few others. Even then there is only room in RAM for four or five apps. Most of the listed apps in the multitask bar have long been removed from memory.

Not that this makes any practical difference if you run a lot of apps that actually do run background tasks. They still need to be removed if you want the best battery life. I'm only making this point for accuracies sake, and to hopefully head off some future arguments of the general type of my-iPad-does vs my-iPad-dosen't. It is about what you are running, not how full your RAM is.

At the risk of turning this into a comment on the XSysInfo app, I have looked further into the figures. I started the thread looking for a quicker way of closing the apps which appeared in the multi bar, and I thought were using up a lot of RAM.

Then I saw the reply about XSysInfo, which appeared to be what I wanted.
The figures for available RAM shown before and after using the clean function of the app were impressive. However even after using it, the app icons remained in the task bar, leading me to think that this app does not close open apps, but really just regulates memory usage.
After cleaning with XSysInfo I typically reach 80 + Mb free RAM. Then after manually closing all the apps in the multi task bar, it increases to about 128 Mb.
I would welcome an interpretation of this result, and still think that Apple should have thought of this problem when iOS 4.2 was introduced. As I said there are several Android apps which close selected programs with one click, and it is strange that one has not been developed for iPad.
Apple wants to sell more batteries! Come on .........they are dumb?
Just been drawn back to this thread by the seemingly irrelevant post above. The issue is memory usage not battery life.

I don't think this is of benefit to users and in another post on the effects of poor memory management on ipad1 while using ArtRage, there is info on this.
"Over on Xzone's (the developer's) site, they talk about how Apple removed XSysInfo from the iTunes market.
Apple removed app from sale because of this feature. We were asked to
remove memory cleaning from app. That's why app was not sold from 1-st
september till yesterday.
We hope that we will be able restore functionality of our app soon. Stay
Please don't upgrade and make a backup copy of version 1.4.4.
1) At least they themselves are warning people not to update.
2) It sounds like they are hopeful that the feature may return in future releases (though Apple may think differently)."
The thread on the forum is here.
][Moderator edit: No links to external/other forums, please.]
It is a real problem in ipad1, and I now address it by rebooting more frequently, which is a pain.
Added after more searching: a thread from Mickey 330 a Super moderator
From XsysInfo to Sys Actvity?
"In defense of XSysInfo, it has gotten yet another update. Now, you pull the screen down (similar to pulling down to refresh) and it'll clean the memory. It's not as good as the original version - it's slower to clean and you don't have the deep clean option - but at least it does some of what it did in the first place."
This seems to have restored the memory recovery function, though I am not sure why this wasn't publicised after the update that caused the problem

Reason: Additional info
Off topic, but even the developers of Android task killers say you don't need them (they did help about 3 years ago, but not now). That being said, the interwebz is full of people who still use them. However, there have been several people at work who were complaining about Android's stability and looking at iPhones, but as soon as I uninstalled the task killer, the problems went away. IMO, Google should just remove them from the market, or if devs were honest, they'd post it in the description. I can't seem to find the interview with Aaron La (the developer of Advanced Task Killer, which is one of the most popular ones) but even he admits you don't need it.

My two cents.

That's because you were looking for the wrong name ... and the wrong thing.

One caveat. In my experience, Remove Background does not work well if you've set it up to have your SBSettings display in the Notification Center. I had to remove the tweak because almost every time I went to use it - I'd crash my device and it would respring (and sometimes go into Safe Mode).
So, now I use a tweak called "WeeKillBackground Pro for Notification Center." It puts a line in your Notification Center and all you have to do is tap it to empty your multitask bar. I have the Pro version ($.99, USD), which lets me customize the font (color and size) and the size of the line in the Notification Center. However, there is a free version available (WeeKillBackground for Notification Center) that only gives you a line in the NC (not customizable) - but it still works fine.
Remove Background may work for you. Regardless, here's two options for removing apps from the multitask bar.
