    You don't have to. And you don't need a task killer. This isn't a Blackberry.

    I don't understand why VZW reps tell people to install a task killer. They did for my friend and gave some bs reason. They don't know anything about the OS itself. Honestly, the task killer makes his phone run worse.

    No, not really. The Android operating system has its own way of dealing with background apps, and a task killer is not really needed. This is a much debated topic on the forum. However, I have NEVER used a task killer and I've never had a problem with battery on my Motorola Droid (my X isn't here yet). My phone is also overclocked to over twice the processing speed..which uses a lot of battery.

    If you're on your home screen and you go into settings - about phone - battery usage, it gives you the percentage of what's using your'e battery. My apps are hardly ever there.

    Give it a try if you like. Go into the market and download "advanced task killer" or something of the sort. Go one day without killing anything and see how your battery does. Go one day with killing everything once you're done. I doubt you'll see a huge difference either way, so I'd rather not have to open an app and kill stuff as soon as I'm done.

    I just got my Droid 2 yesterday, so I'm here looking for answers. BUT....
    The only way I've found (from online info) to exit an app is to back out of it. In the case of Pandora, the music keeps playing. I would think that not only drains your battery, but also uses up your data? Yes, I realized pretty quickly that I need to switch to the unlimited data package, but still.... there must be a better way to exit apps?

    You can exit the app but pressing the back key. You can also do it in your settings/applications/manage applications. But certain apps will still run in the background even if you shut them down. That doesn't make them a battery killer.

    Data, now that's interesting I never thought of that since I have unlimited data. I would pause Pandora and hit the back button, can't use data if it's paused.

    The article copied below is specifically about task killers, but it gives an excellent description of how the android OS handles apps.

    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.

    Simply put, the android os will officially shut an app down after it determines you're not using it. If it is something that is required to stay in the foreground, it does. Certain apps, like Slacker, for instance, has an exit from the menu that allows you to shut it down. You can always go into settings and shut down each app individually.

    The task killer is unnecessary.

    Even jumping off an app via the home button will eventually lead the app to be closed by the os if left long enough. Drain the battery? Maybe a little....certainly nothing to make any changes or add a task killer over.
