Life without an App Killer

    After reading on here that task killers were a MUST have I was running advanced task killer. However my phone has been lagging recently and after reading a bit more people were suggesting Task Killers were the cause of this.

    I uninstalled Advanced Task Killer and installed Android System Info.

    Since unistalling the Task Killer the phone is much faster in general, by my perception.

    Using Android System Info I can see that available memory is at times about the same as after performing a kill, suggesting that Android handles resources well left to itself by auto killing apps or processes when ram is low. It shows info on when the system considers ram low and starts killing apps as well as loads of other system info and logs.

    Looking at the Tasks tab shows how many apps are running and the memory used, but crucially also shows the CPU usage of thoe apps. Generally the Apps in memory are using ZERO cpu usage !!

    My quadrant benchmark with Appkiller was 538, without it is 567. Not massive, but still BETTER.

    I would like anyone to comment on the following:-

    1. Does Killing and restarting apps decrease battery life due to increased CPU Usage ?

    2 Does memory itself use Battery life if the items in memory are not using CPU ?

    3 Does having low available ram matter when the CPU actually does the work and can Android kill fast enough when Ram is required to meet an applications requirements?

    4 What... is the air-speed velocity of an unladen swallow?

    Thanks in advance

    It certainly can do, if Android is constantly reloading apps that you are killing.

    No, memory is always on and doesn't use more power jsut because there is something "live" in it. This is somewhat of an simplification but when RAM is emptied it is not really physically emptied, the OS just notes that those bits can be overwritten whenever they are needed for something else. Even if the system was designed to set all bits to zero, that wouldn't actually make them use less power in real terms.

    The Android task manager is very well designed and you shouldn't ever need a task killer app. If you do need one, it generally means you have a poorly designed app and you should blame the dev for that. Having low RAM will cause swap to be used more often which can then slow the system down a bit, but Android does its best to sort itself out when that happens.

    An excellent question, and one that is not covered in this well-written article where an Android dev discusses the subject of memory and task management in some detail. However, I recommend you read it regardless :) .

    i have uninstalled my task killer, replaced it with:

    You set the limits as to when different variations of tasks/apps are killed. So io set them slightly higher than android default to ensure my device runs smoothly always

    lets you stop apps turning on at different points, such as when wifi turns on (why does a system widget care about this?), and when you receive an sms (wtf doubletwist?). This makes sure the phone is always running optimally.

    The sheer fact that so many people got the Python thing just proves that we're all geeks.......or students. Lol

    I followed you and did the same, uninstalled Advanced Task Manager & installed autokiller. Set it to the "optimal" preset. Would request some help with autostart though. I think it needs some script or something to make it work?

    I use optimal too, with autostarts just click on the tags to see which apps open on that event, and click on those you don't want to open to disable it.

    I have not diabled any system apps/tasks, only ones that have nothing to do with that particular task.
