Should i use a task killer? Atk?

SHOULD I USE A TASK KILLER?
The tips&tricks thread (nice by the way) answered;
"Absolutely not. You have the best OS and one of the best spec'd phones ever. You would be doing more harm than good. If you do have one, uninstall, reboot and let me know what you think!"
I don't get it. You'll be doing more harm than good? Right now I'm using Advanced Task Killer along with Auto Task Killer and it has definitely made a difference in my battery life.
Why would you NOT want to have these apps?
I'm confused LOL

I don't use one at all. I don't see the need for one on this phone...

It surprised me when I did see all the programs running ... would it not be of a benefit to close those for the sake of the battery? I found this to be very true and it was a noticeable with my battery.
I'm just trying to figure out why that other guy would say to uninstall it. Reasons...

I was using one for reasons of speed, but I stopped using it and I honestly did not notice a difference in performance or battery life. So for me, I will no longer be using a task killer. I simply don't see the need.

In the time of low spec'd Android phones it was need. But with phones with fast processors and lots of ram its not really needed any more. Some people have said it even slows down the phone.

Task killers are a waste of time for any phone that has 256 RAM and up.

I'll let others chime in, but the reason I put that in the sticky is because I listen to those who know more than me... and EVERYONE who is in the know with android (developers and google) suggest task killers do more harm than good. I did not intend to come off harshly in the sticky, but I don't want those new to android thinking this is something they need to do.... when in fact, it could cause a lot of problems and they would not even be aware it was the cause.
Hope that helps, a little...

OK, like the OP, i do not get this claim that Killers do more harm.
Suppose you started a game which took 50-100K of your valuable RAM. Even if you have 500K of it, not much is actually left for apps. Even if you quit playing the game or other memory hungry app, it often still hangs in memory. Eventually you will have several pages of different apps which you've used over last days
What's wrong is with kicking them from there? How can this be harmful? That's sounds like a nonsense.
Don''t you all know also that unused memory is switched off by power management to save the battery?

Hahaa... okay, you are correct. Google and the ROM chefs are all wrong. Android is not capable of killing off apps when they are no longer needed. Everyone, rush to the market and immediately start killing off every app the second you close it. Especially the system apps you never use.
Alright, enough sarcasm (didnt mean to sound rude). Like I said in the sticky and above, I am only quoting those MUCH more knowledgeable on the subject. I will admit I purchased a task killer 2 years ago... and I hate seeing it under "Downloads" in the market as "Purchased" now. If you feel the need to kill off apps, so be it. But for those new to Android (and those who are very familiar), it is mine (and others) opinions, especially on the Vibrant, to not use a task killer.
Even Google at Google I/O 2010 told app developers to no longer add "Quit" or "Close" into their apps, as they were NOT needed.
This thread helped me. I have cleaned up the Sticky with more input. Here is a good article from a few months ago that sums it up well (also now in the sticky):

To the OP, thanks... this did help me and I'm certain a lot of others were probably put off by my vagueness. Do you think this makes it better now? Anything else needed you think?

I really appreciate your dedication and yes it did help me built onto my knowledge base. As I always tell people, "If you don't know what you don't know then YOU DON'T HAVE A CHOICE, however, if you do know than YOU THEN HAVE A CHOICE."

I really think using AutoKiller is a better method to controlling what you have running in the background.

Finally someone to educate the masses ... time to get them off this task/app killer *CrAcK*

As said previously. Maybe worth using them on a G1 but not on any recent phone.
For those who do think it worth running them. How quickly do new apps open? Lets say you kill 30 apps, how long before 30 new apps are running? 20mins? If it's such a huge drain on resources why has google not fixed this issue, its been around since the first retail offering G1 with android 1.1? In fact, as previously pointed out google does not recommend even using task killers. I would say using a task killer to kill the apps is a far bigger drain (cpu, battery) that allowing android to as it was intended.
Android is not like windows. Android will shut down and make available what is needed. It does not need any help.

They cause more problems than good. Task killers slowed my phone down more.

The problem with task killers is two fold.
First you have to really grasp what you are killing. Many apps and services are interdependant so killing the wrong app or process can result in apps dead-ending, or worse locking up and taking all the cpu task time (which will make battery use worse).
Second, everyone's phones are different. We may all run an identical build of 2.1 on our Vibrants, but I'd wager each of us is running a different set of 3rd party applications, so anecdotal statements that "task killers work" don't necessarily mean anything, other than for you specifically.
Here's the bottom line. So long as you do not have a buggy app taking ridiculous amounts of cpu time your battery life is solely dependant on what you are doing with and have installed on the phone. The Android Service UI does an excellent job of handling task management, providing those 3rd party tasks are behaving. Apps on the market do not go through an orwellian level of scrutiny like on the Apple App Store, and many (if not most) are currently in a constant state of development owing to the explosive growth of our smartphone platform.
And one additional tip thanks to the Vibrants styling. As the phone is incredibly thin, it's quite easy to feel when the cpu is a crankin! If after you've locked your phone for 10 minutes or so the upper middle back is warm? You probably have sleep issues with an app or apps.
In essence welcome to beta testing, even if you didn't realize it. And welcome to the consequences of an open platform.
Use the built in battery stats, market apps like spare parts, and you can likely discover what 3rd party apps you may have that are giving your battery grief. The level of detail you can gain from the built in stats in 2.1 are excellent and immensely useful, providing you use them.
In my experience apps and widgets that routinely poll for data and interrupt the phone's sleep process are the main culprit you can control. And the OS's built in battery usage statistics can really tell you what is going on.
Some apps may look cool and do great things, but if they're interrupting the sleep process or eating entirely too much cpu when they are active, you're probably best off trying one of the gazillion alternatives to that app available on the market.

I flash my occasional ROM, but am not a developer of any sort. this post has been great insight into my many attempts to "protect" my phone from the running apps. I did start to notice that advanced task killer was asking me to shut down system processes that I would never know what they do. Now obviously I can see the third party apps and scrolling widgets that needed to be closed when I finally let my device sit, but after uninstalling ATK I have found that my device is actually running more smoothly.
FYI - a simple battery pull at the end of the day has been my best medicine.
thanks for the discussion guys!

I hope that was meant as a jest.

Never used one on my G1 from the day I bought it an I was one of the early adopters, and now to the Vibrant.
I've always had awesome battery usage and I just use my phone. I've never used a task killer in my PC so I don't see how this is any different.
Task killers are IMHO a waste of space and money if they charge.

This is one if the best threads on XDA about task killers. I will make a point and link it in the sticky thread also. Really encouraged by the Vibrant forums.

From what I have heard, tasks when you first load a rom need to run to configure. If you keep closing them they will keep trying to run to do what they need to. So, it actually slows you down.

TRY TASK MANAGER by ADAO TEAM

I know there is probably gonna be alot of heat about using Task killers or not but this is just to suggest to the people who are interested in using a task killer/manager but don't know of a good one for there EVO.
ive tried other task killers and they all created FCs and resets. task manager by adao team is the only task killer that ''I'' found that works great with no FCs or resets. task manager is awesome it lets u auto kill tasks with a set time interval after your screen is off instead of instantly. it also lets you kill system services. it really does help my EVO and i can suggest it. also it was recently updated to work with 2.2. try it out and let me know what u think. make sure to ignore things that are important to you such as mail messages etc
like i mentioned before this is JUST A SUGGESTION
try it out and give your thoughts about how you like it
please do not leave your thoughts about how u think Android O.S doesnt need a killer/manager

i didnt know they allowed ads.

i saw that someone was having issues with 2.2 and a task killer so i thought id make this thread about task manager bc i like it.

Wrong section

the only issue with task killers is that people use them.

Task Killers are only good for garbage apps without an exit button, such as the ad infected generally overrated TuneWiki

So funny to listen to people regurgitate what they have heard regarding task killers. The OP made it absolutely clear that it was only a suggestion and it has helped him out and he wanted others to try and NOT respond about why they are bad. I have run both my Droid and Evo with and without a task killer and notice a substantial difference in smoothness when they are running. I just switched over the Auto Killer and have enjoyed even better performance. To each their own.

How does one get Music and Voice Mail to stay killed?

thank u.... someone who actually can read correctly

if you want better performance then overclock your cpu, yes some poorly made apps need to be killed, but you dont need an extra app for it, android can do it natively. why even use those poorly made apps.

blah blah blah blah...I'm guessing you are one who hasn't used one, but jumped on the "I've heard it from everyone else, so it must be true" bandwagon. I am not a noob and I can tell you for a 100% fact that there is a noticeable difference when and when not using auto killer. Programs open quicker with no stutter, screens switch quicker/smoother with no stutter, scrolling through app drawer is 100% smooth with no stutter. All of this cannot be said when relying on Android to manage application memory.

Well, it depends on how you are using Auto Killer. If you are only using it to tweak memory management settings, there's no danger. You just give the system more aggressive values for its built in task manager. This is definitely the best way to tweak task management. If you are using it to kill individual apps, then that could be a problem. I used to use task killers, and then when I heard about the problems, I decided to test it and see if the claims are true. This was back on my hero, so we are talking the slightest difference is very noticeable. When I did a factory reset and didn't install a task killer, I realized that the system was running smoother and didn't get random force closes (a big problem in 1.5 and early versions of Android). This performance actually got better over time as Android became more efficient at knowing which apps to kill and which to save.
Basically, if you let Android handle things, you'll get optimal performance, as that's how Android was made to work. If you use task managers, you may notice a difference, but eventually they start causing issues in the system and the actual performance is degraded slowly. People who have switched away and tried a fresh install without task killers have noticed a difference in battery life and overall performance. Tweaking auto killer's settings to a more aggressive setting is ok, as long as you don't go overboard, as that changes values that Android uses in low memory situations.
Also, I am not a noob. I might not be a dev yet, but I've been using Android since 1.0 on the G1 and do know quite a bit about how Android works. That and I read all the Android development blogs and hang around here a lot. So I have a good mixture of experience and knowledge. Please, if you think I am wrong, tell me how so, but from my experience and from the Android team's own statements, I'm pretty close to right.

To kill or not to kill
to use a task killer you have to really know what you are doing to not affect the performance device (if you knew then you wouldn't have one but I'm just sayin...). I have used one since the day the hero came out, and I just recently stopped using a task killer and the performance of my phone has drastically increased. This is an FYI to people who read this post, not an argument to the OP.

Android does a TERRIBLE job at cpu management

Ok, so I finally bought into this whole "task killers are horrible especially on froyo" bit and have not used one for a couple months and have factory reseted my phone between then and now.
There times my phone barely functions. I am currently listening to music and it skips every few seconds because the phone is so slow. Why isn't android killing the background apps? Sure, in a FEW HOURS it will be working ok again but give me a break. Why is it so bad?

Where is the music you are listening to? Your sdcard? Pandora's servers?

I use a task killer. I have no problems with it on Froyo. Sometimes my phone is running a little slower than I'd like it to, and I use the task killer and it helps. I really don't know why people have such a problem with task killers. I think it helps me more than it hurts, but if someone wants to chime and fill me in as to why they are frowned upon, maybe I'll change my mind about them.

I always used a task killer mainly cuz I think it improved battery life a bit and also never bought into the anti task killer mentality. But since Froyo no longer lets them completely kill the app I've stopped using them. To me they seem unnecessary now.

I don't think its anything that the phone is running in the background. I think its the kernel you might be running. I am running Netarchy 4.1. 9.1. And it does that, I was also running KingxKlick #4 I believe when it was doing that.
Try using a different kernel.

I think the OP needs to be a bit more specific. What music app? Is everything slow? Custom ROM or stock? Did you try wiping both caches?
This problem wouldn't be considered normal for anyone. So either it is an easy fix, or you might have a defective phone.

Need more details, what ROM & Kernel are you using? What apps do you have?
I use a task killer but only manually and only kill apps I know don't need to be open, it works great. You just shouldnt use them if you are one of those people that wants to kill every single process that is in memory.

Are you using the BFS or CFS version? The BFS version did that to me as well, CFS runs perfect though.

I still wanna find the person that wrote the development guideline that says that apps shouldn't have a Quit option in the settings. It's one thing to back out of an app to do something else, then come back to where you left it. But a lot of times, I KNOW I'm finished with an app, I want to release its resources NOW and there's no Quit option. It's probably some of these that don't let go nicely that cause me to have much worse battery life one day than the next.

Give them a good punch for me. Add a QUIT option next time!

Please be helpful to the op guys.

OP, if you haven't done so after you stopped using a task killer, you should do a factory reset. One of the issues with task killers is it can mess up the way Android handles tasks automatically. So if you do a factory reset and don't run any task killers, Android gets pretty efficient on its own and you shouldn't have any more issues. If you are using a custom kernel/rom like others are saying, then you'll want to try switching Roms. Remember to do a full wipe any time you switch roms/kernels. Also, if you are using Titanium backup when switching, don't replace everything. I had a lot of issues when I did that because it can replace some things that won't work right when replaced on a new rom. Plus, if you are having performance problems, it can also be caused by a specific app or service, and restoring it will only bring the problem to the new Rom. I suggest using App Brain to backup your apps and Titanium for only a few specific things, like Scenes and SMS.
Try the Factory reset first without installing anything. Give it a day and see how well it performs. If that works, add things back and see if it still performs well. If that doesn't work, try a different Rom if you are using a custom one or a new kernel if using a custom kernel. If stock, then you probably have a specific app that is causing issues and you'll want to uninstall it. Android will remain pretty speedy if you don't use a task killer as it learns and becomes more efficient at handling tasks.
To all those that say task killers work great, the reason you don't understand the issue is because you haven't read how Android works and how task killers interfere. They are bad, and even Google's engineers say that. They wrote the platform, so I'd recommend that you follow their advice. You can really screw stuff up with a task killer and overall they don't actually help you at all. Most people find that they use more power and resources than they end up saving, since if they are running on automatic, they are actively using resources to stop apps. That, and the system uses more resources to restart an app after its killed, which will worsen battery life and resources more than if you just let it run. Most "running" apps are actually just sitting in memory, doing nothing. When Android is running properly, it manages the memory, keeping it mostly full of apps that it thinks you might need in the future sitting there. If you open an app that isn't already in memory, it chooses to close other apps that you are less likely to use to give back enough memory for the current app.
In short, if you are having issues with Android not managing resources properly, its either because you screwed it up using a task killer, or you screwed it up with some mod that interferes with Android's resource management tools, which will either make it unstable or break it completely.

PSA: Stop using Task Killers!

Buddy Chris says it all:

I use ATK, but only for Engadget because Engadget goes over my CPU limit thingy on watchdog.

Yup, he explains that use it for things like that

There are still lots of users putting their faith in TKs. This is good advice. Hopefully more users start listening.

Lol this guy is corny. He talked too much though. No reason that should have been 7 minutes long.
I do my best to educate all my fellow Android users on the best way to manage their apps.

Um, I don't need to watch the video to know that it went too long and sucked.. he's not amusing. Having a 7 minute video for a simple subject is not cute
I have to use a task killer without touching the system ram managment settings. The phone runs out of enough free ram to run ram intensive applications. Android's free ram management system is nice, but it's not perfect. When the phone only has ~50MB free and no other applications are running, you HAVE no other options besides rebooting it or killing everything that's running in the memory. Android phones need at least 1GB of ram to keep everything running smoothly..
I can attribute a ton of lag issues to a lack of free ram.

I personally use auto killer memory optimizer or something like that. Its worked wonders for me and keeps my phone running smoothly and battery life good. I Haven't had any issues with it personally.

Agreed with this. I've constantly read about how task killers don't help and they're useless etc., but on my HD2 the fact of the matter was that killing tasks would make my phone significantly faster and reduce battery drain by around 5mA (equivalent to a standby drain of 1%/50 mins going down to 1%/1.5 hrs). I haven't found any need to use any automated task killer with hardware this good but I don't see any reason it would harm the device at all either. I guess killing something which needs to be open (and thus will reopen itself soon enough anyway) could cause unwanted battery drain, but other than that there's no problem with task killers.

there are other ways to manage memory. i like to use the autostarts app on my devices, you can prevent apps from starting up in the first place. also, i like using the auto memory manager app to change androids memory management numbers.

I believe its different.. It just takes out the apps from your recents section. Even if I have a kill button on my custom rom, the app will still appear in the recents menu.

its the same to a point. some roms come with a longpress back button to kill option too.
the whole task managers are bad thing started when cyanogen made a statement about them. people were killing their launchers and widgets(widgets would stop updating), and creating false issues for themselves then blaming cayanogenmod for for their troubles. cyanogen didnt want to deal with these people so he made a statement that task killers are bad. since then, its been blown up more than the "issues" that they create.
