task killers?

can anyone recommend a good task killer? ive tried atk on 2.2 but its very sluggish. i dl task panel x and it doesnt update frequently lol. i have autokiller memory but not sure if i am using it right lol. so if anyone is using a task killer, what r u using and r u getting good results? thanks in advance!

Do not use autokiller. I can't remember what problem it causes but it does indeed cause a problem on all galaxy phones. Or at laast my fascinate

You shouldn't need one from all I've read about it.
but I use system panel to kill an app here and there.

Don't bother using a task killer. I used Advance Task Killer for the last two weeks but it probably hampered things more than it helped. Your phone will NOT slow down to a crawl. Most custom ROMs use good minfree settings that'll keep your phone snappy.
Just uninstall your task killer, or if you want to use it, turn off autostart, turn off autokill, and only use it for pesky apps that won't die.

I was using ATK and could not verify any benefit. I read the following article and gained some more understanding. I have been running without a Task Killer since and I see no loss in performance or battery life. I could say I have less FCs and more reliability with syncing email.
Read This: http://lifehacker.com/5650894/android-task-killers-explained-what-they-do-and-why-you-shouldnt-use-them

i have been getting random shutdown these few days (started like 3 days ago), about 1 shutdown per day. i'm not sure if it' the stock task manager, dolphin browser beta 4.0, or widget locker 1.2.7 causing it. i already removed stock task manager and downgraded widget locker to 1.2.4 to see what happens.

Task killers aren't generally needed on android. If its battery life you want then for one try not to compulsively look at your phone preventing the cpu from idling and screen from turning off. Get juice defender. It turns off data unless it is needed. Most apps don't use resorces when the phone is asleep unless they are designed to, like file sharing programs or apps that sync data in the background but there are also bad apps. In froyo Use the built in task manager (long prsss on home) to see what's running. If you havent used something in a while and don't need the process active then close it.
If it is performance you want then no task manager will help. You need to alter the minfree setting which manages memory and how apps use it. I use the one click lag fix app to do that. Other apps I used caused problems. I set the minfree to moderate. Its more agressive than stock but doesn't kill processes you might want running. Anything more agressive than that kills allshare while im streaming movies but there is a performance increase when set to optimal or strict however it is slight.

[Q] ignore Apps in 2.2 Task Manager

how the title says how can someone ignore Apps which are need like (sms time fix) when one clears the memory and not having to restart the app every time after clear memory

Just don't use the level 2 clear and you'll be fine. Only apps you should ever kill are the ones that show up in "Active Applications". Except for your launcher of course. Killing system apps and services is like shooting yourself in the foot.

How so? Could you elaborate?
I'm sincerely curious as to why the L2 clear is a bad idea.
Thanks, dude!

Clearing L2 level cache kills essential android processes too, and system would again need to restart all the needed ones again. Read abt 'android memory management' (link in my signature), and see if that helps.

App data is stored in RAM so that you use less CPU the next time you run that app. RAM uses much much less power than CPU, why would you want to have empty RAM?
If an app in your task manager shows cpu % next to it, then close it because you don't want the CPU to be used at all.

As the previous two said, why would you need to have RAM free?
This is not like BBOS, which needs like 25% memory free in order to start an app.
The whole reason for having high RAM is to use it, if it is always free (unused) what benefit do you get from it?
Using task killers or freeing up memory in order to save battery is only going to drain your battery more.
Android loads programs into memory based on what it deems needs to be available to run quickly... and once you kill it, it will use CPU to load it again shortly thereafter.
CPU is a bigger drain on power than letting programs hang in memory.

[q] best autorun task killer

Please tell my which is best software that stops applications to run automatically at startup
tell me the application which works

no one is using any app. to stop unnecessary start up of tasks

try autostarts its very good

Ditto on Autostarts. Also, Autokiller Memory Optimzer works really well, it doesn't kill tasks itself, it tweaks the Android function thar does it to work better.

auto killer mem optimizer workd well for me.but now i simply don use any of those batt saving app,mem apps etc i jus kill apps in inbuilt task killer...iam using my phone to the peek cause at the end ill b getting a 2ghz dual core by selling sgs.......cant stick to old things lol........cheeerz

Google it. Android is Linux based. Its memory management is not the same as Windows. I'd explain further, but you're the 4,753,857,195 person to ask.

I spent 10s and googled it for you. Here's a quick link that explains it in simple terms.
http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
Basically having applications in RAM is a GOOD thing. Constantly killing them is likely to WORSEN PERFORMANCE AND BATTERY LIFE.

That's right. On the other hand - permitting almost every app to load at startup isn't the best approach, as you will soon run out of memory - therefore using apps like autostart makes sense imho. But constantly killing everything isn't the right approach either. Android removes "old" apps automatically.
Bottom line:
- just letting those apps load at startup, which you use on regular basis, is fine
- using a "ram tweaker", auto-kill app, etc. is not
Kind regards,

And when you run out of memory, Android will free memory by automatically killing cached (unused) apps. Therefore, I don't see the point of stopping apps from running at start--unless they're actually doing something in the background and not letting your phone sleep.
RAM tweaks (or memory management), on the other hand, is the only thing I use. I adjust OOM settings to adjust which apps Android closes to free memory, as well as how much free RAM Android should keep open in various situations.

Well actually I don't see the point that an app, that I hardly use once per month should be loaded everytime I start the phone or change my internet connection. Also more apps at startup increase the time when the phone is available...
But on the other hand, you are certainly right, after a while, only the latest apps are still in background / memory. What I have recognized nevertheless: if you use a lot of apps with push functionality and load on startup, the phone runs out of memory...
Kind regards,

Autotask killer bad for our battery!

According to Juicedefender battery saver-Autotask killer bad for our battery & which cause more battery draining.they directely said that avoid auto task kill.Is it true?
share your thoughts on that i,e sentence.
sent from sgm 5570

It really depend on how u use ur phone. If u kill task that u do not yse fir a long time it actually save ur battery on the ither hand if u kill an app amd then run it again it will drain mire battery. Also dont kill system app they will just start right up which lead to battery drain. I personnaly use advanced task killer and set ignore the app u often use, dusable autokiller and set security level to low to avoid killing system. But it just a matter of opinion really so just decude for ur self.

yes, it's better to kill app's manual

I also using two different task killer, but never set them to auto.. just like other opinion, it's true iff we continuously set the app to kill system or app we recently use, it might be drained our battery more effectively.. theoritycally it's just like you do the same task all over again in the same day.. wouldn't it gave you more exhausted than you do it only one time and manage to do it the other day..?

Here, i give you a reason why autotask killer is battery draining.
#1. Android kills app every 15 minutes when phone is almost out of memory, Android drastically pushes old app process and kill them so currently running app can be running. AutoTask Killer kill app foreground & underground apps process, underground apps generated by app itself, and generating underground app is use some battery & CPU cycle. Android kill app only it's FOREGROUND apps which still save alot battery rather than generate another Underground app which eats battery & CPU cycle.
#2. AutoTask killer kills system app. System app generates more cache & underground process than user apps, since system app always runned by Android for some reason (at JB 4.2.1 it's managed more extensively). Just like reason number 1, underground & cache generating in Android consumes ALOT of battery.
#3. Task killing consumes CPU Cycle, CPU will need to get it's higher hertz to keep speed, higher the CPU, more battery killed
#4. Task killing MAY free RAM, until Android generate another cache which eats up X2 RAM than old cache, since new cache refreshed and need to be intergrated with apps. More RAM, no More Multitasking !
#5. AutoTask Killer make apps process blocked, which slow-down apps, since app cache is deleted. To make the app keep smooth, CPU is set to it's higher hertz, just like reason number 3, higher CPU, more battery killed.

so a ram manager app or a script for ram is better?

Actually it depends on how you use. I use Advanced Task Killer pro to kill apps after a session and to monitor which apps open by itself and run in background. Those apps are the ones I freeze in titanium backup pro. Some of them are Google Maps, Facebook (I use it rarely, FB app sucks)
Dont use the scheduled auto kill option, that will drain the battery.

A little Tip
Our mini can't handle a task killer. I suggest you to not use any of them.
If you want to kill an app, use the "long press back to kill" option in cyanogenmod.

[Request] Process manager/Task manager

I am wondering if we have a task manager/process explorer app for Nexus 4? Currently I am using AirDroid v2 that includes a task manager, but I am looking for one with more options.
I travel a lot & would like to kill as much unwanted applications running in the background as possible to conserve battery.

There is no more need to use task killer to manage android systems any more. You will be doing more harm than good, in fact there is no good in killing tssks manually.

Point noted.
But when I use Airdroid task manager, I see a process when the corresponding app is not running the background.
To mention a few; Cut the rope free, stocks & Hill climb racing.
Few system process like picasa uploader, chrome etc.
As you said andoird may optimize most of them, but I would like some control when running thin on battery.

use greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=en to hibernate any persisting apps/processes (except system). apps relaunch when you open them.

Killing apps and then having to reload them actually uses more battery than them being dormant in the background and already loaded when called upon. The problem is when you have misbehaving apps that stay in the foreground eating up cpu, instead of going dormant into the background. And this does happen. I use an app called Watchdog that alerts me when this happens. It allows you to kill the app when this happens. It also allows you to whitelist and blacklist apps and processes.

fast reboot(free), but the paid version i like better https://play.google.com/store/apps/details?id=com.greatbytes.fastreboot&hl=en

rayiskon, I will try greenify & let you know how that helps.
fernandezhjr, I agree restarting app is not an optimal way, but I require to squeeze battery to atleast make phone calls when I am away from charging options.
simms22, fast reboot looks promising. I'll try the free one for now and take it from there.

It's kind of already been said, but I want to clarify as much as possible.
Apps running dormant in the background (using RAM) use no more power than if it weren't running. This is because all of the memory you have is being refreshed all the time, the controller has no idea whether there is actually data there, it still refreshes the entire space of memory.
Apps running "dormant" but using CPU do use more power than if it weren't running. I assume OP is wanting some sort of monitoring app that shows which apps are using CPU, in which case is fine. If OP is wanting to kill all apps that he isn't using at the time to conserve battery, then he would actually be doing the opposite of what he wants, as it requires to CPU to spin back up to restart it later. Again, the difference here is RAM vs CPU, one doesn't use battery (or rather, uses the same amount of battery, no matter how much of it is being utilized), and one can use more or less battery depending on how much it's used.

Thanks for the detailed explanation. I understand killing process, shutting down cached process or apps & later restarting them is only going to fire up the CPU usage which completely defeats the purpose of conserving battery.
Though not a daily ask, at times I am stuck in situation where a phone call or SMS is all I need to keep me going.
