I don't know very well in deep Android os, I'm wondering if the apps that automatic close unused process can help the phone and the battery or only damage the normal kernel work.
NO. Don't use auto task killers. Please.
If you MUST know whats running, use something like WatchDog, which lets you keep an eye on wary tasks, but doesn't kill anything unless you specifically say so. Although you can do this manually with the built-in Android one, WatchDog gives you extra tools to use.
Task Killers have been horribly misused and not at all required since Android 2.2.
Nay on task killer. Android does pretty well on it's own.

Auto killer isn't a task killer. It tweaks android's default values for killing tasks.
This is the only "task killer" I would say doesn't hurt the system itself.

Check the dev options in settings. You can adjust some of the settings there.

Yes. Let's go "optimizing" the system by killing tasks and tweaking system thresholds without any metrics what so ever, besides saying "it feels smoother" (after a full reboot with no new apps loaded, but lets not mention that. it sounds less awesome).
That sounds all so very scientific and I am all for it.

Umm...there are a number of programs in the Market that can show you cache hits and page faults, etc. It's not that hard to get some measurements for what effects these tweaks are having.

Has anyone seen any benefits in using task killers or managers on the Evo? Has it helped or made battery life worse ? Do we even need them with the Evo ?
in my experience the phone runs smoother if you keep running tasks to a minimum. i have an app called ES Task Manager and it comes with a widget that has one touch kill all. i hit that and turn off the screen when i'm not going to be messing with the phone for awhile.
I used to use Advanced Task Killer (ATK) and loved it until one day my phone would not work whatsoever. It kept force closing HTC Sense and I had to do a hard reset last week. It was very upsetting and the sprint technician said the task killer was to blame.
I agree. I switched from Advanced Task Killer to ES and it's great. Really helps out battery and smoothness. I can get about 12-16 hours per charge when doing that with normal use.
What's ES?

I use Damage Control 3.2.2.1 with its built in killer set at 150 MB with Advanced Settings Part 2 Laptop_OOM activated and JIT. Banned everything except Facebook.
Then I use autostarts to stop programs from starting up at boot, speeding up boot time and using less power.
Credits go to TheBiles.
I can usually get about a day and a half of regular use before I reach 10%.
Best tip? Don't use any task killers..
At most use autostarts and thats it.

Estrongs task manager
Task killers are a bad idea on Android. It's best to just let the OS do its own memory management. The only reason to use a task killer is as a last resort for a rogue app or something like that.
There's a thread about this around here with a detailed explanation as to why this is true and how memory management works in Android. I can't copy and paste because I'm sending this from my phone. And I'm lazy.
Autokiller and autostarts are probably the only two apps that make sense to use and this is to enhance management, not override the built in management like task killers do.

Ugh this is why I hate the debate.
Some people say use it... some people say Android's memory management is fine.
My ATK usage is simple. I close programs that I do not use and won't start any FC's.
So basically after I'm done playing a game, I use ATK to close out of it.
I leave most things open unless it's like Sprint Zone or something.
I decided to be less lazy for once.

simply put, if you have any linux experience you'll realize why task killers aren't neccessary like in a windows mobile platform device.
I use ATK. As far as battery life, I haven't seen an increase or decrease, but the phone runs smoother and sometimes an app gets stuck, so I kill that sob off.
Use Autostarts only. It is a permission manager--not a task-killer.

I tried ATK since the BB Mobile guys were pushing hard for you to install it before you even left the store with the phone. I gave ATK an honest try, and experimented with most of the settings. At the end of the test, I found that ATK didn't really help me. That being said, my battery life is much better now since I moved for the rooted stock image to Fresh 0.3.

Heh, BB Mobile reps always act like they're experts. These guys know less than the average XDA forum reader. They'll have you think otherwise though!
As much as I disliked the idea of not managing my own processes, be it by manually killing them or with some automatic thresholds, after some reading, I decided to let Android handle things as it was designed to do.
To satisfy my itch for being "in control", I downloaded (from the market, for free) an app called MinFreeManager, which allows for you to tweak the parameters for Android's memory management. I also read a suggestion from Flipz to use AutoStarts to better control what apps are starting, and when. AutoStarts basically lists events within Android and allows you to toggle if an app should run or not.
That said, I've noticed my Evo has been very smooth and responsive. I periodically open TaskKiller to see how much available memory there is and to be nosy. The truth is that apps do clean up and are disposed of properly by Android. Give it a shot for a few days. What's the harm?
I see that people have those apps running; its in the status bar.. but is recommended? I just want to make the use of the phone to run on its max without performance loss, as we all. But before, in other forums.. Froyo didn't need any of that... ??????

Sent from my T-Mobile G2 using XDA App
U don't really need a task killer. I don't anymore. I just force stop only the apps that hang or stop responding other than that what's the point of killing an app if its just gonna start back up. 2.2 does a really good job of memory management anyway. If u don't want an app running in the background temp root and uninstall it.
Sent from my T-Mobile G2 using XDA App
From what I remember reading, in Froyo their Kill API is handled different in such that the application/service isn't really "killed" it just restarts.
I could be wrong, but my understanding is that memory management and simply just management as a whole is much better in Froyo. I only use a task manager just to see what's running. If something does go haywire or hangs, then I'd step in. Otherwise, I just like the information being displayed; makes me feel like I know what's running back there.
This is from the developer of Mobile Defense:
"Note, we do not recommend installing task killer applications. These type of apps have the ability to kill other running applications with the promise of freeing memory. Not only are these apps unnecessary but they also waste battery and introduce instability by killing necessary processes. Google Android Engineers and leading Android developers are beginning to speak out against task killer apps:

Even the developer of Advance Task Manager admits that it's not needed on new devices!
Arron La, developer of Advance Task Manager, suggests that task killers are more important for legacy devices like the G1 and phones running older versions of Android.
“Task Managers were absolutely needed in the past before the new services UI came out in Android 2.0 or 2.1,” La said in an e-mail. “Task Managers had a niche of allowing users to quickly kill services associated with apps – including all the other stuff as well, such as alarms – but that was the only way to do it before the introduction of the new services UI.”
Task killers only cause problems and eat up your battery.
Taskillers only for Android < 2.1
On Android 2.1 and later there is no need for task killers, the OS handles memory and apps much more efficiently than in older versions of Android.
Task killers were needed for the best performance on Android before 2.1 but overusing them could be detrimental to performance also.
My general rule is no task killers on 2.1 and later versions but sparring use of task killers on anything earlier.
To me taskers kill ur battery because they r always running. I use hot reboot it restarts the phone from bootscreen not from the slash. So it takes me about 14 too 17 secs to restart my phone. Sense i use my phone for almost everything. Rebooting to kill all apps and start from fresh is good for me sense it takes no time to do so.

yeah i wonder how to remove/uninstall apps such as stocks which i do not even touch at all.
The best method is to uninstall your task killer. They are junk and will only slow your phone down. Every time you kill those process, they have to restart which uses more cpu and battery than just leaving them in memory in the first place.
Please google about android task managers and you will find some good explanations as to why you shouldn't use them.

You need root and some form of s-off. Then you can either delete with root explorer, titanium backup, out adb.

Like dr.m0x said, those task killers and other optimizer are the worst thing out there on the market.
Android handles these things just fine. If your RAM gets low it will kill tasks on its own. And if your RAM isn't low - then why kill tasks? Free RAM doesn't help at all.
Also background apps almost never use battery/CPU power. If you don't believe it check the battery usage history. And most background tasks have a CPU usage of a couple of seconds.
About removing stock apps, a nice and clean way is to use ROM Cleaner (download in the dev section). It removes apps from the ROM before you flash it.

I am running Cm7 and my wife is running konis elite III (Sense) and just wondering what task killer or manger is the best for those 2 roms. I'm currently using "super Manager" to clean up RAM and a cache cleaner on my cm7. If anyone knows of a good task killer for cm7 and sense that would be awesome! Thanks in advance!
I have had no real trouble with memory management with either of those roms. This has been a topic of debate for a while, to task kill or not to task kill, I personally have found that Android runs better with out a task killer. Since Android 2 came out it has built in memory management which works pretty well I might say. "Personal Opinion" A lot of people think that Android runs like a desktop computer/laptop. In that you open an app and unless you close it it stays in ram/memory never letting the space go unless the app is closed. Android on the other hand does this a little different. When an app is opened it is in the foreground and has priority over other apps. Other apps are run in the background. Now if an app is opened that needs memory that is being used by a background process then the background app is closed, saving the state if handled correctly, giving the newly open app the space it requires. There are a lot of details on how this works and what I said is a cut down version of it.
Basically, using a task killer goes against how Android handles background tasks.
Task killer no good
I'd advise against them. Personally never had to run them. if you still want one, you can look into tasker, juice defender; some that others use.
Task killers/managers died in android 2.1, its now known that they cause issues with the way android handles memory/processes. Your phone is smart enough to close or keep something running on its own.

I agree. Besides that, CM7 is a Gingerbread (2.3) based ROM. IIRC, 2.3 has slightly better/enhanced memory management over 2.2 as well - the garbage collector. 2.2 and 2.3 handle their memory management very well from what I see and read.
Concurrent garbage collector — The Dalivik VM introduces a new, concurrent garbage collector that minimizes application pauses, helping to ensure smoother animation and increased responsiveness in games and similar applications.

More often than not, over-aggressive task killing running in the background can actually cause system instability and force closes if you run a lot of processes.
To add to what's already been said, a task killer is not only possibly harmful, it's a waste of time & counterproductive as well.
Most of the stuff that's running in memory is just sitting there, waiting to be reopened again. It isn't using any power or wasting battery, nor is it slowing your phone down. It's staying there so that when you do open it again, it opens more quickly instead of having to reload entirely.
Android will close those apps if/when it needs the memory. There's no need to have a separate app to do it less-efficiently.
Cool! Thanks Guys! Thats what I pretty much figured 2.2 and beyond but just wanted to double check.
Hey, I noticed that in the screenshots section that everyone has a task killer, aren't they bad for android? I've read that they were needed for android 2.1 and down, not after Froyo.

samsung roms (even stock) have default task killer called "Task Manager", for active apps and if you go to Settings > Applications > Running Services, you can kill apps running in the background or cached processes. The difference is, the default tasker does not have a "Kill All" feature.
Task killer is, well not recommended, because Android has "Low memory Killer" feature, which, from the word itself, Android will kill apps as memory is needed.
It's still up to you if you want the default tasker, or a 3rd party one.
I hate that Samsung put that there. I've always been told that you let android do its job, unless there is a runaway process.

If you ask me a task killer gets you more battery life and helps reduce data usage by killing apps that you are not acctually using.
Sent from my SAMSUNG-SGH-I927 using XDA
yes but even if you kill some apps they reopen on their own. I am referring to the stock Rogers rom and that dam AP program.
the reason task killers are considered bad is becausw most people blindly kill everything. your phone has a lot of tasks it will automatically relaunch, thus wasting more processor time in the end. if you pay attention to which processes these are and exclude them from your kill list, you can safely use a task killer.
i also suggest apps like autostarts, lots of stuff like to start that dont need to.
im newly registered but not new here! just picked up a glide yesterday and put cwm/osi on already. a keyboard is a must for me and this was the nicest phone i found with one. my d1 was overdue for retirement. i use sipgate/google voice for free calling, texts and vms (wifi) so thankfully carrier didnt matter. very happy with this thing so far. cant wait to see some ics roms?
Advanced task killer shows you which apps automatically restart and lets you disable them from being killed
Sent from my SAMSUNG-SGH-I927 using XDA
Automated task killers generally are bad voodoo because they interfere with Android's own memory management system. Android micromanages memory like you wouldn't believe, and task killers will only slow things down by interfering with it. In particular, you'll lose significant performance and battery life as the phone works harder to reopen apps that could have just been sitting around in otherwise unused memory as intended by the OS. (And of course, the auto-re-open thing mentioned above.) I used to keep a task killer on my OG to troubleshoot misbehaving apps (sometimes killing the process and forcing it to restart would right some issues), but now that Android has the running services dialog, there really is no need for task killers at all.

It was an excellent phone. Mine finally locked up the other night while I was out and totally died. Doesn't even get the M Moto symbol when you start it up. It had been dropped countless times, entirely submerged in a puddle, whiskey spilled on it. But it soldiered on until the other night. I was even running a very broken ICS ROM (dead project now) on it and it was just as fast CM7. I ran it constantly at 1GHz which impressive for a phone that was stock 550Mhz. Most phones, even the Glide, you can't overclock by more than double like the D1. The fastest kernel I ever had on it, I had edited a version of ChevyNo1's 1.2Ghz kernel to allow 1.3Ghz. I ran it like that for a few days and it was stable.
Great phone. It truly deserves a burial at sea with a 21 gun salute.
