    I have the free version of ATK. I know to get auto kill, I need to buy the $4.99 version. My question is... if I set up an app to autokill it, then can I still open and use it? I have apps auto opening. Pandora is an example. I don't want it open unless I want it open. And I've read some of the discussions regarding memory/CPU/battery useage. Maybe a task killer is needed, maybe not. But privacy is one of my concerns as well. Will I still be able to use Pandora, etc. if I sit it up to auto kill?

    I know about the opinion about task killers and yet I bounce back and forth with using them. I can tell you this, right now I'm using ATK as well, the free version. I've selected what apps to have it kill at the interval I set it at. On my D1 (see sig) I don't know that the app made a difference and don't know that I'll keep it on there.

    However on my DX I was noticing that when I was playing Angry Birds it was not running smooth, and it had been before. Immediately I thought it was my clocking and I set back to stock to see if it helped. It didn't. I went in to ATK and hit the button to kill selected apps, and it cleared it right up.

    I know based on the article that they say that the OS decides what to close when needed and such, but that doesn't mean that it always happens correctly. I'll be keeping it for a while on the DX. The apps I have that I don't have it kill are things that I want to make sure are always available (like emails, text app, ATK, GV, etc) or when I'm using, don't want any interruption.

    So, given the experience with the DX, I think it does help.

    Task Killers Per Lifehacker:

    Android Task Killers Explained: What They Do and Why You Shouldn't Use Them
    How Android Manages Processes

    In Android, processes and Applications are two different things. An app can stay "running" in the background without any processes eating up your phone's resources. Android keeps the app in its memory so it launches more quickly and returns to its prior state. When your phone runs out of memory, Android will automatically start killing tasks on its own, starting with ones that you haven't used in awhile.
    The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.

    Why Task Killers Are (Usually) Bad News


    Apps like Advanced Task Killer, the most popular task killer in the Market, act on the incorrect assumption that freeing up memory on an Android device is a good thing. When launched, it presents you with a list of "running" apps and the option to kill as many as you want. You can also hit the Menu button to access a more detailed "Services" view, that lists exactly which parts of each application are "running", how much memory they take up, and how much free memory is available on your phone. This set-up implies that the goal of killing these apps is to free up memory. Nowhere on the list does it mention the number of CPU cycles each app is consuming, only the memory you'll free by killing it. As we've learned, full memory is not a bad thing—we want to watch out for the CPU, the resource that actually slows down your phone and drains your battery life.
    Thus, killing all but the essential apps (or telling Android to kill apps more aggressively with the "autokill" feature) is generally unnecessary. Furthermore, it's actually possible that this will worsen your phone's performance and battery life. Whether you're manually killing apps all the time or telling the task killer to aggressively remove apps from your memory, you're actually using CPU cycles when you otherwise wouldn't—killing apps that aren't doing anything in the first place.
    In fact, some of the processes related to those apps will actually start right back up, further draining your CPU. If they don't, killing those processes can cause other sorts of problems—alarms don't go off, you don't receive text messages, or other related apps may force close without warning. All in all, you're usually better off letting your phone work as intended—especially if you're more of a casual user. In these instances, a task killer causes more problems than it solves.
    What You Should Do Instead

    That said, not all apps are created equal. Many of you have used task killers in the past and actually found that after freeing up memory, your phone works a bit better. It's more likely that this is because you've killed a bad app—one that was poorly coded, and (for example) keeps trying to connect to the internet even when it shouldn't. Any performance increase you experience is more likely because you killed the right app, not because you freed up loads of memory (or, in many cases, it's just placebo). Instead of killing all those apps, find out which ones are actually causing the problems. If you really know what you're doing, you may benefit from using a task killer to stop the one or two inefficient-but-loved apps on your phone.
    Note, however, that this is still a contested notion. A lot of developers (including ROM builder extraordinaire, Cyanogen) will not even look at your bug reports if you're using a task killer. In this humble blogger's opinion, your best bet is to stay away from regular task killer usage entirely. If you absolutely have to have that one battery-killing app on your phone, though, kill away—just be aware that when you experience a recurring Android bug later on, the task killer may be at fault. Of course, you can just stop using it to determine whether that is or isn't the case.
