A couple of days ago I decided to wipe my phone which was running cyanogen's 4.2.13 because it felt slightly sluggish and I figured it was because I've been through so many rom updates and havent wiped, coming from before the whole google/cyanogen cease and decist.
i wiped the phone, reflashed 4.2.13 and enoch theme and began restoring all my data and apps. I noticed very strange behavior coming from the phone shortly after this though. sometimes the phone would just become completely unresponsive, not even the red button would put it to sleep mode. only option was to pull the battery which allowed the phone to run fine after a reboot.
this has happened a total of 3 times since I wiped/reflashed it (monday night). today it happened again and I decided to let the phone run until I was able to open advanced task manager. to my surprise, about every single application I have on my phone was running in the Applications tab. after killing all, the phone was back to being responsive again. I did not execute anything to open these apps, the phone simply started lagging out and I suppose the reason is because every app was trying to get some use of the CPU.
now I am keeping a heavy watch on my advanced task manager list to see if this will happen again, and I noticed that the Messaging application has spawned itself on the list. is this normal? is something wrong with my phone? has it been compromised? I haven't downloaded anything strange, just the same apps I had before wipe/reflash.
No your location hasn't been compromised and there isnt any spyware or viruses on your phone. Those are services, just like on computers that do numerous things.Sometimes settings becomes active after using power control.You could just put the widget for the taskiller on you home screen if your concerned about speed. If your home screens are filled with hundreds of widgets try removing some and see if the speed increases.The 10MB hack might be helpful if you switch b/t a lot of apps.Or you could try another rom if you wanted.
im pretty sure an app like AK notepad doesnt run as a service, but it was populated a few times on my applications tab, along with other things such as calculator.
i don't use the power control widget either. leaving the task killer widget on my home screen to kill the processes as they fork bomb my phone is just a sloppy way to fix whatever is wrong.
and my home screens arent filled with widgets. the only widgets I use are weather, calendar, curvefish's bluetooth wifi silent screenlock, and overclock widget.
If all your apps keep running in the background try using advanced task managers auto end list
It started driving me mad. If I minimize browser, I can't be sure it won't close. Not only minimizing for longer periods, but short ones as well - wanted to reply an sms when a page was loading, but when I got back to it, it started over. And all the loaded tabs were gone! Saving states my ass, it takes time to load a page from zero and only the active browsing window remains. How to make this "multitasker" multitask?
does this also happen if you return to the browser by holding home?

Yes, that's the only way I switch betwen apps.
Have you installed the 'system-based' taskiller mod by any chance (you know, the one that was announced here that automatically keeps memory free by modifying the default thresholds for killing apps)?
If so, I reckon that's the issue! Either that, or you have too much running, so popping the browser into the background makes it a background task and it gets killed cos you're really short of RAM.
Let us know if you have used the tweak though...
@kengdong...
it doesn't matter how you change the apps.
For android it's the same, whether you tap an icon on a homescreen/list or whether you select it from the "task switch" thing... all that does is listing the last recently used applications but still tapping them results in the same internal action.

I've had pretty much the same issue since I got the phone back in November (I guess I've just gotten used to it by now). I'm never really sure when I switch back to the browser if it will retain the page loaded and any other windows, or if it will reset, close the other windows, and have to reload the active page. I'm on the stock Telus ROM, no custom ROM, not rooted, no tweaks, nothing extra (I've been waiting patiently for 2.1 to come out before messing with custom ROMS).

No, I have stock rom and I have never used any task killer or related app / tweak.
And I don't run too much stuff.. only music player, messaging and sense's facebook perhaps. If music player is paused, why can't it quit it instead... I prefer multitasking of my past htc s730 which had like 7 megs of free ram after booting.
Even after a hard reset, this behavior remains.
i dont know.. it works fine for me....
1.. maybe there is a setting in the browser.. to always refresh.
2.. you have a repair issue.. Need to take it in to your local service provider repair center. Let them see your issue.

Come on, it's no hardware issue. Most of the time the browser stays, but u just can't be sure about that because it sometimes just closes. I think that it's an issue with Android's STUPID memory management, which also has a scheduled "quit all" script.
Yesterday I opened up a few articles on the browser and decided to read them later. This morning they all remained and I was pleasantly surprised I could read them. This very moment, though, they are gone by now even though I haven't quit the browser - probably that 'quit all' script kicked in.
There could be something in settings, where you could chose apps which would not close ever unless quit..
I would love if Android apps were quitable without any automatic mem management.
Suggest to grab AutoKiller or MinFreeManager, which are just frontends to Android's memory management (also they reapply settings at boot time, as the system file that's being modified is reset every boot.)
See what your current settings are, and lower them (e.g. use "moderate" preset). Just search XDA for autokiller or minfreemanager for more info.
Pressing home should only move that application to the background (pressing back should close it).
If you are pressing home and applications are still closing then there must be a task killer of some sort in place closing it for you.

No task killers, tasks dont neceaarily close, its juast that u cant be sure they will remain in memory.

Yes - it's the standard Android process management rather than a 3rd party task killer.
I guess the browser is given a low priority and is one of the first apps to be killed.

Hi
Ive just got this app (really to save myself some battery time)
On launching for the first time it presents me with a whole bunch of stuff including my clocks
Now i'm sure this maybe a pretty dumb question but if i kill the htc clock App will that stop the time and weather updating correctly? (i have my weather set to update hourly) and also if i kill any app like K-9 or Peep (that i have an update schedule set for) will it stop that schedule till i manually launch the app again or will it auto launch when it reaches the sheduled update time?
Sorry for the (potentially) stupid questions
Cheers
The only thing you're going to achieve with using a task killer, is lowering performance and causing even worse battery drain. If that's what you want to do, fine, but otherwise, I wouldn't bother if I were you.
Here's why:
Android's memory management is nothing like Windows Mobile. Applications you've finished with are MEANT to stay in memory until they really are completely finished with, and just because YOU aren't using them, doesn't mean the phone has. If they've been inactive long enough, or some other program needs the RAM, Android will tidily close them down.
If you close them prematurely, then Android will have to load them back up again, so that whatever was using said program's services, can continue to function. This noticeably affects phone performance, and puts an extra load on your battery. Do you REALLY want to do that?
I'm not using any task killers, and my phone runs great, and battery is up to 2.5 days.
Hmm interesting, i might try that, im killing all instantly and repeately, thanks for the tip

Thats correct.
I installed it on the phone, and the battery was empty the same night
Uninstalled it, and all works fine now.
Greetz.
would an app like task panel work?
you can add apps that are system apps etc to the ignore list and have apps such as games on the force to kill list or is it just best not to have any task killer apps installed at all?
its strange that there are so many task killer apps and its bad to run on your device. There must be some reason as to why there is an app for this purpose?

They exist, because people think memory management on Android works like it does on Windows Mobile. It doesn't, and never has. Think if it like the so called "memory manager" tools you can get for XP that claim to be able to free all your RAM and speed up your system... Every single one of them is nothing but a placebo designed to part you from your cash, and often end up CAUSING problems, just like task killers on Android do.
Avoid them.

Guess thats a good enough reply lol
task killers can work fine, but you need to know what is running and what is using it.
for example, if you have the music widget on the homescreens, then the music player process will be opne in the background.
likewise friendstream will keep people, facebook and twitter open in the background.
if you kill those processes, they will just get opened again.
As long as you are careful, using task managers will not decrease battery life, you just need to know how to use them properly. randomly killing everything in the background is NOT the way to do it.
and you should never close clock if you want your alarm clock to actually go off!!
Might be worth making a list of what apps should be ignored and what apps can be forced killed?
When i had an app killer installed, i used to only force kill games and sat nav apps, the rest i asked it to ignore but after reading this thread, i decided to delete the app killer app =)
Ive put a bunch of stuff like clock, weather, Peep and facebook etc on the ignore list and have used the task killer to only kill off frivolous apps like Spark (for xbox friends) streamfurious, photos etc...Nothing Major!
I unhooked my phone from the power at 7:30 am on the 13th April, its now 16:36 on the 14th april and it still has 30% of the juice left, and i always have wifi and mobile data connection on too...phone is always left on with facebook connecting ever 4 hrs and peep once a day and mail set for every 2 hrs (besides which i do check and update them manually a couple of times a day)
I'll try all this without task killer installed and test how long the phone can run before charging
As you say, it could well be a combination of the battery coming up to speed and a placebo effect.
However, surely it cant do more harm than good to kill an app like Spark !
However, im no Phone Genius so im sure someone will soon tell me that im completely wrong
But so far so good....like i said, ill test things without task killer installed
I've stopped using the task killer now and my battery life has improved very noticably.

im not so sure about this.
im using a task killer when i want to close the browser or something using internet, as we all know internet drains a lot of battery and even if the browser or market is in the background it still probably has some active connections = draining battery

If you want to close fast the browser or any app, you should have a try at taskOS and launch it with the search key whenever you want...
Binned this app in favour of Juice defender, my new battery saving app of choice, seems to be working as it should too...nice

but then that works pretty much like a task killer
can anyone correct me about the apps i.e. browser using internet while not active(in background) is this true or not? of course having the sync/updates turned off
Task killers can be handy for those times when apps seem to have crashed but aren't forcing close. for example, i've had times where ebuddy just doesn't want to even try to sign in. Task kill it. Try again. all is well. And last my internet browser wouldn't let me click any buttons. Again, killed it - restarted - all is ok.
I've had to use such an app countless of times due to unwanted/unneeded apps running, hanging FCs and black screens, checking/closing net related or sensor using apps, and numerous times when 300KB apps wouldn't install citing 'low memory' when I have more than 70MB free, but it was the RAM being near full causing FCs in apps like Market, and halting the installs. I only use Androids built-in TaskPanel widget for this though. Everything routine is set over to the ignore list so that I don't accidently hit and close that (single hit closes the app). Additionally I use this app to check and to switch to an opened application that is running (when it's not in the recent list).

This is the route I've taken naturally. I'm using jkAppSwitch on my longpress search key, mainly used for switching but can be used to kill problem apps.
Full task killers are being proven to be useless on the Desire.
I would recommend using an app that monitors the cpu usage(watchdog etc.). This way your can see which apps put a drain on your phone.
Thank you for the information. But I do notice a considerable improvement in battery power with Advanced Task Killer.
I hope someone can provide me an answer.
while phone looks like its sleeping the apps are still working and using the processing power for whatever they are doing there behind the black screen.
and theres alot of apps that need to sync or update or pull data off the internetz
would that be a possible issue of standby battery drain?
i mean i can turn my phone on at random times and there will be 10-20 apps running in the background when i didnt even use them.
they just start check something and sut back down.
can i stop the apps from autolaunching?
remove task killer and run auto killer .. also use autorun killer to stop certain apps from starting. I would caution you to be careful what apps you stop. You make cause important apps not to work.

If there are apps running its cause they have a task to do. You can manually change your syncing to stop these apps from starting. Also try autokiller and set it to aggressive. This way the apps continue there task and android shuts them down faster than normal
Thanks for the tip. I have both running. I haven't stooped any apps from running with autorun killer, I'm hoping it does it on its own. The other is set on aggressive.

So Samsung for whatever reason, decides it's a good idea to include an easy to access task manager with a giant "kill all tasks" button in TouchWiz. It seems like everyone I know, that has a Galaxy S II, has adopted a certain behavior due this. What they do is, every time they put their phone away, they will automatically go to this task manager and kill all tasks, before locking the phone. When I ask them why the hell they're doing that, the answer is usually something like "wasting battery blah blah blah" or "wasting CPU blah blah blah"... NO!
For starters:
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
http://www.infoworld.com/t/smartphones/myth-android-devices-need-task-killers-609
http://androinica.com/2010/05/googl...-imply-task-killermanager-apps-are-pointless/
People that are doing this, educate yourself. And Samsung, well done for encouraging this.
Just because a task is in memory, doesn't mean it's doing anything, and certainly doesn't mean it's using up battery. If it's staying in memory, it's because there's no need to release it just yet. If you start it up again, it will already be there, and load up faster. The alternative is, you keep killing it, and every time you run it again, it will have to reinitialize and reload everything. Which option do you think is actually going to cost more battery?
The whole thing with people saying "oh no it's using CPU, i must kill it"... what?! If it's using CPU, it's probably doing something. Why the hell are you killing a process while it's in the middle of doing something? Do you not care about data integrity at all? It could have been in the middle of syncing, or in the middle of a write operation who knows.
If you run other applications and your memory runs low, then Android will close it. And it will close it properly, as opposed to you force killing it, denying it of any chance to clean up.
Obviously there are rare exceptions with dodgy programs. But most of the time, the tasks being killed are system apps, or trustworthy apps, properly written by Google or Samsung.
If you're not a developer, you probably won't understand the whole Android application lifecycle.
http://developer.android.com/reference/android/app/Activity.html
By force closing an application, you're not allowing it to run its onStop() and onDestroy() functions. This is where apps do all the clean up, releasing resources, unregistering things, closing connections etc.
Do you do this on your PC. Open up Windows task manager, and just kill any task that's using CPU. Or hell, just kill all tasks every 2 minutes! Good luck with that.
This has probably been said hundreds of times, but a lot of people i know are getting GSII's and I see them doing this constantly. It's stupid. Do you really think they designed the operating system so that you have to kill everything each time you touch it?
TLDR: Stop "killing all tasks" (unless theres actually something wrong) and well done Samsung for encouraging this. Just stupid.
Damn your right, I never used a task killer on previous android phones, but for some reason I have got into the habit of doing it now. So I'm going to kill that habit. Well noticed
Well according to the user guide (the full one from Samsung's website)... though personally I don't bother killing anything
Use the task manager › ›
Your device is a multitasking device. It can run more than one application at the same time. However, multitasking may cause hang-ups, freezing, memory problems, or additional power consumption. To avoid these problems, end unnecessary programs using the task manager.
1 In Idle mode, open the application list and select Task manager → Active applications.
The list of all the applications currently running on your device appears.
2 To close an application, select Exit.To close all active applications, select Exit all.
i like the placebo effect and stop telling me what i have to do or not to do!
your writing style is to aggressive, stop being aggressive!
For me, it is worth to have the clear memory option because I already faced the glitch or bugs program which cause my phone to run constantly at 1.2ghz and this will cause my phone become extremely hot. I can't see what application is running but for some reason, the cpu gone crazy. It drain battery in no time. With the simple one click button, I can closed the programs without need to restart the phone. Yes, generally I will let the android system to handle the application by itself but I still think it was a good moved by samsung to have task manager if we use it in proper way...

Well it's not all that bad, with 2 cores one core can easily come into a deadlock and the device will continue to function albeit much slower and consuming a lot of power, when this happens in the taskmanager the processes are listed red
Thanks ever so for much for this post I have just got my first Android phone and thought by doing this it would increase the battery life a tad but did kinda think it was a bit daft having a system that required manually killing tasks. Coming from a Windows 6.1 XDA Zest I am still getting my head round an OS that's doesn't require hours on Internet to work out how to do things.
Sad, but true, I was getting onto Android from Symbian, and first thing after I realised that I do not have option of killing all apps, I have installed the task killer and kept using it for like a week, then I've read one of the articles about it, that its wrong, and that Android is not working as Symbian nor Windows, so I realised that I dont need to do that... unninstalled it and not using it at all since
You don't need Task manager / killer if only all android applications are developed by good programmers that implement Android application lifecycle properly.
The problem is not all applications are developed this way. Some application may buggy / in beta stage that still consuming processing time even they are in background.
Task manager is still useful to close nasty program manually. But I do agree, auto-kill is useless and can cause battery drain and system instability.
Yep .. it's mostly services what eats battery. And there is poor control over that. It would be interesting to see what service was active at what time, or even how much battery did it use. All battery discussions are about guessing what is running in the background and how often and how much. We should not guess such things.
As far as I'm concerned an in built task manager is just as important as an in built modem right now. There are far too many unstable applications out there that hang up and Android can never fully deal with them(despite what research may or may not have been done in the past).
I have a few games installed on my S2(namely Pool Break Pro & TNA iMPACT!) that crash quite often and require the use of the task manager to manually end those programs(they are in the task manager highlighted in red when they have stalled).
However, what I will say is that the button to clear memory in the RAM manager really shouldn't be there at all. The task manager alone is more than enough to manually exit necessary apps that crash and stay open for no reason.
I like to have the ability to close programs easily at hand. It gives me better control over "rogue" apps. I only use it for a few programs though, like the Engadget app. It seems to be poorly coded, often using 40-50% CPU when running in the background.

Lol yes. Not to be taken too seriously.
Force closing apps with the task manager when somethings wrong with the phone or closing broken apps makes sense. I'm just talking about people that instinctively press the close all apps button every time they use the phone for a second. It's just silly. Basically doing what those automatic task killing apps do.
I use to kill opera everytime i'm done with browsing because even in idle mode the phone gets very hot when opera runs in the backgtound. But after these explanstions i stop force killing every app

If a program is badly written and won't stay idle, then kill it.
I am very selective about what I install, and never kill or need to kill anything.
You have 1 GB of ram on this phone. If you want best battery and speed, don't kill anything. loading a running app from ram uses less power than starting from scratch and booting it from nand, then starting it up.
So if apps are well written, don't kill them. If stuff stays around causing drain, kill it individually but find a better app
This thread is spot on... for the most part. Like Pulser said, there are apps when idling/cached, cause detrimental effects like the one I detailed here causing your phone to stay Awake constantly and draining battery:
http://forum.xda-developers.com/showthread.php?t=1094666
ATK isn't the most elegant method, but it allows you to put everything else on ignore and have it actively kill the apps that love to stay cached and cause issues even after you've exited out of them.
Is there a way to "lock" some apps into a memory so they never quit by the android OS except if I would decide to?
Sent from my GT-I9100 using Tapatalk
You have a valid point, but most of the time those apps don't do anything critical that it would hurt to interrupt. I usually prefer to exit them normally, but sometimes I just kill it, like when I forgot the Messages / Internet open. No need to paranoia though, leaving a few open won't kill your battery.

That's exactly what I needed. There are some apps, like SetCPU, TB, Root Explorer, which can be added to SuperUser authorization and it won't get killed by anything unless someone manually kills it. I'd really really like to know how to add an app under SuperUser or anything which will do the job to add the app in to the OS and which can't be killed by any Task Killer or anything.
Besides I also hate those Task Killer apps, they are meaningless unless an user do nothing regularly with his/her phone.
I've no Task Killer installed but once I used the built in Memory Clear feature and next day my schedule app got closed. From then I never touched it. But one thing if RAM usage goes above 400 MB I think sometime its good to clear the memory as it will help to refresh it. But Samsung should had put the Memory Clear feature more precisely.
Regards.
