    What your task killer is showing as running is not what is actually running. It is, instead, showing what is loaded into memory, waiting to be used. As you even mention yourself, the OS will load up your memory so that apps it thinks you'll use are faster. So a full memory uses as much power as empty memory.

    To find out why battery life is improved when running a task killer, you need to find the rogue app(s). The best/easiest way to do so is see what are the items using the most battery. Why? Because what is using the CPU is using the battery. The top items tend to be cell standby/display/android os. Others can be higher based on usage (it is a percentage-based metric after all).

    Of course, turn off the meory management/task killers to get the most accurate view in the battery usage list. Once you/we know your top battery hogs, suggestions can be made for alternatives.

    Yeah, yeah.. I'm on my phone. So?

    Advanced task killer is not opening the apps, those are the apps that have opened themselves, and that are running or that are sitting in wait in the background, u will find that u can not kill "forground" apps via a task killer & in most cases you dont want t to depending on the app & its role & what its going to do after u kill it.

    To be more precise, you don't want to autokill apps at all. Hrdnhvy is correct, ATK is not opening apps on you, those apps are relaunching themselves after being killed.

    The OS is designed to keep the memory fairly full, so that if you want to use an app, there's a good chance it is already in memory and will load faster (look up Windows and prefetching if you want a computer-based explanation). Any apps you autokill will just be restarted so they can be used (and yes, this includes apps you never use because one day it may be needed or it is tied into other apps that you're using).

    Notice I keep saying autokill? That is bad, because you can get into a cycle where you kill an app, it launches itself, it gets killed and on and on. Some apps need to be autokilled, however they are badly programmed and should be replaced/upgraded ASAP. For the few times that an app goes bonkers, you can manually kill it in settings (or just reboot the phone).

    Yeah, yeah.. I'm on my phone. So?

    This can occur under low-memory conditions caused by memory/resource leaks, and not always caused by 3rd party task killers. I replicated it here:

    I posted earlier about it but i made a big update.
    I fixed memory management problems by rearranging groupings and app priorities...

    [Script]V6 SuperCharger !! HTK & BulletProof Launchers! FIX MEMORY FOR ALL ANDROIDS! - xda-developers

    With real memory management... say buh bye to minfree managers that always stay in memory... plus fix OOM groupings...

    Also, you can use your own settings.
    Use the 3rd slot to set how much free memory that you want

    Before...

    After...

    During....

    En..Have got a new phone. I know that Task Kill is to shut down apps unresponsive. I am wondering is it OK not to install this one. Do you know other ways to end an app unresponsive?

    Now i know that there is something to do with battery. You mean that making a good use of Task Kill can save the battery , right?

    This would be a mute issue if devs were required to included an "Exit" option on all their applications...
