[Q] Are task killers safe for your phone? - GT540 Optimus General

I've read some posts and people said they are killing more battery.Other people said that they're good.So are they safe for your phone,or they can harm it.
I've used task killers since I got my phone and hadn't got a problem.

I found the answer by myself:
http://lifehacker.com/#!5650894/and...ed-what-they-do-and-why-you-shouldnt-use-them

I tested ATK with 2.1 2.2.1 2.3.2 using my phone (Gps, 3g - ON) with same apk on board each ROM and modarate killing and my battery last longer without ATK.
Peace

I got rid of my task killer.I will provide some feedback after some use.Thanks for the reply by the way.

its good n safe if u use it wisely
i ever killed a running system n my phone become frozen

I've been using AutoKiller Memory Optimiser which utilises presets and works well with rooted phones.

i think not

Task killers aren't necessary for Android 2.1 and above. Google has optimized the system so that if you run out of memory, it will start automatically killing unused apps in the background. Even though you might see that only around 20MB of RAM is available doesn't mean it's a bad thing. It means that you can load up your recently used apps more quickly as it is already "cached" in your memory.
Killing apps may also disrupt other system processes that require it to run properly. However, if you want to save that extra battery then a task killer is good to use. Otherwise, task killers are not necessary. I would recommended downloading an app called "Watchdog" in the market. What this app does is monitors your running apps for any memory hoggers. This allows you to kill that app or uninstall it.
This is just my thoughts and may not be entirely correct. Anyone wishing to correct me is welcome to.

Thanks for your reply.I also think that they aren't necessary.In the link above I read that task killers are dangerous for your phone.They are slowly killing your CPU and after some time the phone may start to crash.

Well i'm using a taskkiller and it doesn't do any harm.. And I think it makes my battery last longer.. But that might just be some kind of "placebo effect"

I personally don't use them on my phone, but on my tablet, I use them as it can get very slow without it.

Any suggestions for a good task manager?

Hello, all. I am currently running the free version of Advanced Task Killer, which seems to work ok, but there has to be something better. What I've noticed is, that after a reboot, the app will tell me that I have about 240 MB of available memory when all apps are closed with the exception of the task killer itself.
However, by the end of the day, after I've opened and closed a few apps, sent some messages and emails, made some calls, etc, the task manager will show significantly less available memory available. It could drop to as low as 135 MB with all apps closed with the exception of the task killer.
This leads to me to believe one of two things:
a) The Task Killer is full of it and it does not have an accurate read of how much memory is actually available.
b) The Task Killer is only able to "kill" certain tasks while others remain running in the background and it does not show that the app(s) are actually running.
Honestly, I think it is option B, because I do notice that when the app tells me that I have less than normal available memory, the phone does tend to function slower and lag a bit. Nothing that cannot be fixed by a powering it off and on, but I am hoping that someone knows of a good app (even if it is a paid app) that will actually bring up ALL tasks running and kill them. I've also noticed that even with this task killer, Google Talk (which I have never used) always remains open in my phone and I have to manually go into into the settings and turn that off.
Any suggestions?
My suggestion is to not use one.
I do use Autokiller though which tweaks the thresholds for Android's internal "task killer".
It's best to let Android do it's thing.

Really? Do you mind elaborating on why you feel that way a bit so I can understand? Because I do notice that when the I am running a bunch of things at once and I use this app to kill the tasks, it does improve the performance of the phone.
I can understand why some people say you don't need one but I do think it is necessary to have it installed for when you do. I'd rather kill apps than pop the case, battery cover and battery to fix a frozen phone.
I have some GPS apps I run occasionally that after exiting them they don't turn off the GPS or lock the GPS on and drain my battery. So for those apps where the developer didn't put a close buton on the menu it helps shut them down. I don't know why Google Market doesn't require apps to have a close option.

Because users shouldn't have to manage their own memory. Apple folks already love laughing at us for that very reason, and even though it pains me to say it they're absolutely correct.
I can certainly buy the argument that task killers are nice for those occasions when something does go haywire and it needs to be forcibly killed, and I can understand using one just because you're curious and want to see what's running and how much memory you have, etc, but beyond that I find that they're unnecessary. My EVO runs very smoothly without me manually intervening, even after many days of uptime with many apps running.

Wow! That's detailed and a lot more than I bargained for....lol. Thanks! Good thing my phone is rooted and I was able to use it since I never did the recent update to the 1.47.xx OTA update and I'm waiting for a fully functional version to be released, but there is a lot of stuff on this that goes well beyond my basic knowledge. Apparently, my phone has 89 processes running with no apps running (according to Task Killer) and only one widget running and the CPU is fluctuating at 10-40% usage.
Interestingly enough, but apps report the same amount of available memory......EXACTLY the same. So it can be assumed that both apps provide an accurate figure of available memory.
I would advise against using a Task killer. Android has its own memory management, which works extremely well on the EVO, to be honest. The latest update (1.47) feels like its makes the EVO perform much better and allows it to be more efficient.
If anything, I would suggest you read this thread about an app called Autostarts, which isn't a task killer, rather a startup manager that can be tweaked to do many different things. By not allowing certain things to start up when your phone boots, you'll have more memory to begin with and Android will be more efficient in memory management. I would try Autostarts before using a task killer.
Hope that helps.

I agree, but having to run a task killer is a small price to pay to not be part of the iPhone bandwagon crew, IMO.
Are you running a custom rom on your phone? I just have a rooted stock rom. Maybe that's why your phone can go days without the performance being affected? I still have all the bloatware on mine, and I've put off removing it because I am still a noob at this and I'm in the learning process. I wonder if the new update that was just released improves this aspect of the phone at all.....?

Thanks, I will definitely look into it. All advise is appreciated as I am very new to all of this. You answered my last question on my previous post with this, too.... I can't wait for a fully functional rooted OEM rom to be released with the goodies from the new update to try it out. I'm hesitant to update my phone now and lose superuser as I use the WiFi tether a lot.

Best method for task killing

So since 2.2 I hear you shouldn't use a task killer. What's the best method you take to end tasks?

Let the kernel do the work. Updated stocks are pretty good, but I like Netarchy's kernels better.

The way that 2.2 manages memory makes having a task killer almost unnecessary. However, you might want to keep one handy just in case you get one of those buggy apps that keeps on draining your battery or makes the phone unstable. I personally use SystemPanel app: nice interface and monitoring options for battery life, history, uninstaller and backup-to-sdcard (archive).
Why would you ever want a task killer?
I would like more input on this. I ditched them on my Hero back when I ran CM6, mainly due to the fact that they actually slowed that phone down!
But it seems on the Evo, killing tasks seems to save much more battery life. Or am I just dreaming?...
I have stopped using a task killer since going to 2.2 and have never looked back.

You're dreaming.
Keep a passive task killer around if you like that you can use to kill programs that go completely nuts. E.g. use it to kill a game or app that has locked up or just isn't working right. A passive task killer is one that doesn't actively go searching for apps to kill on its own - one that you must manually tell to kill an app.
If you like, I suggest you try Watchdog Lite from the Market. It occasionally checks your phone for programs that are gobbling up tons of CPU time that may be an indicator that an app isn't running correctly. It still won't actively kill the app though; it just warns you and lets you choose to kill it.
Task killers with Android 2.2 are usually a dumb idea. 2.2 does not have a traditional "kill" command like earlier versions of Android. In 2.2, the same command that would have killed an app is now just a restart command. Instead of the app dying and going away, the app dies and then restarts all over which uses up lots of extra CPU cycles to restart the app. It's only going to save you battery if the app in question has gone haywire.
If anything, get an app like Autostarts that lets you control when apps are allowed to start.
I have systempanel lite.. gives you some nice OS info also gives you a widget to kill apps on demand. I don't use it much but sometimes if I feel my phone is getting a little sluggish. You can exclude all the htc/system/gmail apps etc from being killed. But I agree, do not have a task manager running all the time.
SystemPanel is great. Aside from being a task manager it also is a system monitor and is very helpful in tracking down problematic apps and system processes.
Autostarts is also great, I have mine configured so pretty much NOTHING runs without my say so.
Hot Reboot is pretty slick too, when your phone is starting to slow down and act sluggish. Just do a quick ROM reboot (10-15 seconds TOPS) and your phone is as good as new.
Why not just use the built in one? Settings, applications, manage applications, running tab?

I use System Panel to moniter my phone and AutoStart is a great app to jeep apps from launching themselves again after you close them out. Throw in startup manager and you have a great trifecta of apps.

Alternatives To Task/App/Ram Killers????

Many people say it's harmful using app killers, especially on android as it may interfere with important system resources or close important system files and can do harmful damage in the longrun such as errors, things not working, etc...
When you open various programs such as file manager, picture gallery, etc you then see a list of all running programs in system/task manager.
Many of these running programs are ones you have recently used and are draining ram/cpu/battery.
Is there not ANY safe app to use that will ONLY close apps that YOU have used?
There must be some app out there that closes/kills open apps, not system or phone apps but only the ones you have installed and used?
This could be a ram killer or maybe a simple app which is not dangerous and will safely close running apps not needed.
Looking forwards to seeing what others recommend.
Thanks in advance guys,,,

Names please of a good app that kills ONLY programs you open, not system files.
What if I was to install an appkiller, but instead of having it on autokill, I was to manually click apps I opened and kill them?
Surely this way there is no danger as I'm only closing selected apps, not system files?

The point is, even after killing your own apps, most of the time froyo will restart them
I very much like ES' offerings - ES File Explorer and ES Task Manager. They're both free, give em a birl.
You can install Advanced Task Killer (free) and there you can perfectly select which apps to close and which not... still I rarely use it
for example your homescreen widgets are always unchecked when killing tasks, so unless you check them, they won't be killed...
Hmmm, ok.
What is the BEST way to preserve & save battery/cpu & free up as much ram as possible without harming/interfering with the phone??
When I used to use the task killer app it would consistently give me around 400-424mb free ram.
Without the app killer I would only have around 100mb of free ram since all the programs are running in the backround.
So to all you experts out there, what can I do or what options do I have in which I can safely free up as much ram as possible and safely close running apps not needed when not using the phone?
I just want the best and most effective way to make my battery last longer.
I'm having to charge my phone every day, it struggles to get through the day even when hardly used.
Looking forwards to hearing some expert opinions based on the above.

There's definitely a problem there but you're not going to find it chasing free ram. I have approx 20Mb free ram at the moment, the phone hasn't been rebooted for at least a week but I'm easily getting through 2 days with light use. Task killers / app killers are not the answer, (in froyo at least) free ram is wasted ram.
The programs that are 'running' in the background are not actually using CPU resources unless they have a service running (see the eBay app/service for an example). Your best bet is to check the running services (settings/applications/running services) and battery usage to work out what process is hogging the CPU time. Also check your sync settings, though I'd imagine you've already tried that.

Maybe it's the anipet fish aquarium live screensaver...
Systempanel is good, I use it to stop a bad app thats using to much memory..you should never kill your apps with froyo, the OS wasn't designed like that, thats the whole point of Android, it looks after the apps perfectly well by itself, systempanel is just there as a....just in case method.
Saving battery power is a common misconception, Task killers actually get in the way of Android handling memory management as intended.....a pointless app to have with 2.2 which actually drains you battery quicker.
The LCD screen is the biggest drain on battery power, turning the brightness down, stop using a live wallpaper, turn off wifi, bluetooth, GPS ect....
With all that said the 1250mah battery is just not powerful enough to run this device period...but then most of us knew this before we bought the phone..we needed a 2000mah battery really, its just a lipo battery and can be easily increased, maybe next year we will see an improvement in the new smartphones.

Apps keep opening in background

I have a lot of apps opening up in the background on their own and eating up my memory. Things like qik, skype, city id, vz navigator open on their own even though I barely use them, if at all. My free memory keeps dropping down to around 30mb. Is there anything I can do?
Sent from my DROIDX using XDA App
The best remedy I came up with was rooting my phone, and then installing Titanium Backup and Autostarts. Titanium can freeze the apps you never want to use like some of the crapware that comes preinstalled. For the apps that you do use, but don't want automatically opening all the time, you can use Autostarts to choose which conditions must be met for the app to open, or not open in this case. For both of those applications, you need to be rooted, and unfortunately that's the only way I know of to stop some of the apps you mentioned (especially Skype and CityID).
You can root to remove the bloatware, but that's it. Also, memory on android isn't the same as on a PC. With a PC, clear memory means a faster system, but the opposite is true for android. Because of the way it manages applications, you want to keep the memory as full as possible.

This is the answer. There is a difference in night and day with my X since installed Autostarts and Fission.
If you install Autostarts and use Advanced Task Killer you will be able to kill the apps and they won't continue to run/open in the background. It's extremely worth it.

Search android task killers on these forums. Then listen to the posts and let android do its thing.
Task killers bog down the system because these apps are shut down while attempting to do something (sync, send data, etc). The app then realizes that it needs to complete the process and restarts. This continues over and over hogging your cpu resources and slowing down the system.
Stop paying attention to the free memory and open apps. This is not an iPhone.

You're missing the point. Autostarts doesn't allow the app to start in the first place so it doesn't bog down the system or hog resources.
Correct me if I'm wrong but is it not Gingerbread that has added the addition of a task killer.
It's not about the free memory, my phone runs faster. I can tell a difference.
It's possible we may be talking about different things.
I'm pretty sure closing Angry Birds when it's still open because I Home Screen buttoned out of it won't make a big difference.
If you're referring to closing services while they're running, it's a different story. I skimmed through the article, it looks interesting, but I honestly fail to see how closing an app that's running... even one that might be doing something I don't want it to (like using GPS because it didn't close when I back-arrowed out of it).
When I bought my phone, I installed Weather Bug. Weather Bug kept trying to get my GPS location while I was at work. My phone barely made it through work. Anytime I checked the weather, I had to close the program through a task killer, or I'd have no battery because the phone was trying to use my GPS all day.
How does not closing that save my battery?

That's not a valid comparison. The android system manages apps, but it doesn't monitor everything that they're doing to prevent a runaway (like weatherbug). Actually read the article, then comment on it. And you do know you can turn gps off, right?
I happen to like GPS, and as long as I don't have any runaways, it doesn't drain battery since it's not used.
I'm just saying, for programs like that, Task Killers are great.
I'll read it tomorrow most likely.
I tried Watchdog and a few other task killers before finally shelling out the money for the full version of Titanium. I found that often times, the biggest cpu hog and battery killer was the task killer itself since it has to be constantly running in the background. For apps that you use on a regular basis, the best remedy for saving battery life is to just change the update interval period. By default, a lot of widgets (especially weather) update every 15 minutes, which can be a little tasking on system resources at times. I set mine to 1 hour and that helped tremendously. The main reason I went to the full version of Titanium is because it accomplishes what task killers can't by freezing apps to deny their access to open at all. Instead of removing the bloatware like CityID, VZ Navigator, and others, which will keep your phone from receiving OTA updates, just freeze them and you'll never have to worry about them. Autostarts takes care of the rest for me by allowing full control over the condition changes on the device which trigger certain applications to open. For example, I may use Google goggles occassionally, but I don't want it to automatically open in the background just because I enabled GPS. Before rooting my phone, I would normally average between 14 to 18 hours on moderate usage (with a task killer running I might add). Now, with those two applications managing things more meticulously, and chaning the update interval for all of my widgets, I get around 30 to 36 hours easily.

[Q] Could ATK harm an Android device? (GS II in this case)

Well I had to create this thread. I am using ATk for last three days and it is doing a great purpose to save juice of my battery. But I saw these articles and now I am scared that if I should use ATK or not? There is no performance decrease I've noticed so far after using ATK. So what should I do, uninstall ATK as it could harm my device or keep using it as practical view is greater than technical one.
Please read these, and comment back on the same. I'll eagerly wait for you guys to response.
1- FAQ: Why You Shouldn’t Be Using a Task Killer with Android
2- AndroidSPIN Why you don’t need a task killer app with Android.
3- Android Task Killers Explained: What They Do and Why You Shouldn't Use Them
Regards.
Sure, it might be unnecessary if all things were running normally, but like in my original thread stated, it is the only way to ensure rogue cached processes are completely closed out... unless you like doing it manually everytime.
No, it won't harm it though... if you are asking if it will melt your SGSII over time. Silly question to be honest.
Thanks for your response mate. Well it's very easy to use a Task Killer app like ATK rather than manually killing cached processes. I am sure that a software will definitely not melt my GS II but could there be any problem with memory management? What could be the problem actually?
It won't harm your phone but it might become a little less responsive, because program need to be loaded again and the battery might drain a little quicker using ATK especially when you use autokill because some programs autostart and they keep on restarting and being killed...
It depends on which task killer you use how much battery (if any noticeable difference) it will drain.
Auto kill features should be turned off.
Well I use Auto Kill feature in ATK. In fact after using it there is at least no more non-synchronization of Awake and Screen On bar and that helps a lot to save battery. Frankly I don't see any other option but to not use it. Built in Task manager is not capable of doing a good job, so ATK is the option or the only option left! So I wonder why shall not use it!
