Is there a way to ensure that apps close when I am done with them? I see no reason for angry birds to run in the background, requiring me to close it from manage apps in the settings. ATK is not a good solution for this correct?
Thanks! Guess I'm kinda anal about stuff running in the background.
Also, thumb keyboard doesn't seem to have a closing bracket for [ ?
well since froyo theres been a built in task manager that should take care of apps not being used anymore.
you can use atk or any other task killer but it will suck up more battery
Its been an ongoing debate. Some use taskillers and some don't. I do because I'm on the side of the fence that likes the control over killing selected apps or all apps not on my protected list. As far as battery drain most taskillers have an option to kill itself after you enitiate a kill order. I like, some rely on built in memmory management. Weather its true or not I can feel the difference when I load up large apps like gun bros or netflix without killing background apps.
Setting up an auto kill is what drains the most battery in my opinion. Keep it simple, add system processes to the protected list and have it kill itself after use.
I know on CM7 long pressing the back button kills the app altogether. Not to sure about other ROMS.

Ok I have looked around and have not found the answer. SO here Goes
In windows if you want to keep the memory that you have clear of background applications, you can run system configuration and just remove the check-mark for those items you dont want to auto start.
I have Advanced Task Killer installed and will set it up to auto kill and will manual kill apps as well. Instead of consistently looking at ATK to shut down apps, is there a way to just keep all the apps you not using nor have ever started from suddenly being there and sucking the life out of your battery?
Having applications "running" in the background (i.e., still in memory but in a suspended state) does NOT negatively affect your battery life. These applications are actually just remaining in memory because that memory does not need to be used by anything else at the moment. If an active application gets to a point where it needs more memory, Android will automatically close applications that are in a suspended state (i.e., not actively being used) to make room.
In other words, using an app killer is NOT necessary and I definitely recommend NOT using one. By closing the application repeatedly, you are just causing the application to take a longer amount of time to start up next time you use it. You're making your Android experience worse by using one, not better.
There is one caveat to this, and that is when you have an application installed that doesn't play nicely -- i.e., even when you stop using that application, it will continue to use up CPU cycles (never go into a suspended state). This is actually pretty rare unless you are installing really poorly written programs, but it can happen to some popular apps too (usually the result of a bug). In this case, you should either uninstall that application or use an app killer to only kill that one app.
I've heard both sides of this argument, and don't know who to believe. I didn't think I needed a Task Killer, but then I saw it repeatedly on "top 10 apps for Android" and "must have Android apps" lists from respected sites like cnet... who to believe?!

I need to confirm this. Anyone? I dont care about memory because I bet Android excels at that, and at any rate, memory is there to be used, not to keep it empty.
But I come from a Symbian smartphone and "minimized" applications DO uses battery. Maybe little, but noticeable.
Anyone can confirm that background apps consume negligible battery juice?
Additionally, is there a nice task changer? Like windows Alt+Tab. I feel my Android like an iPhone, that I need to press the home button to move to another already opened app and that's just plain stupid. So far I'm using Multitasking Lite, but it can get sluggish once there are too many apps opened. Any suggestion would be warmly welcomed.
"Running" background apps DO NOT consume battery life unless they're actively syncing. If it's just in the memory saving the state of the app then that is fine.
As far as using a task killer, if you are manually killing apps and they keep starting back up then that is a bad thing for your battery. The app uses cpu cycles everytime it starts up again and syncs data. You can use a task killer to close apps that opened on startup or when you're done with them. If they stay closed until you choose to open them again then you're saving memory, but nothing to do with battery life.

Obviously you can switch over to some apps by pulling down the notification menu and selecting the appropriate app. That only works on apps that put themselves in the notification menu though (multimedia apps and things like Google Nav usually do this).
Otherwise, you can press and hold the home button to bring up the list of 8 most recently opened apps without exiting the active app. This works but like I said, it's the 8 most recent apps, so it will list apps that aren't necessarily still running anymore. It's more of a shortcut to having to go search in your apps menu or home screens to find a recent app than a way to see what is currently running.

What can I say, I hate pressing the home key to hunt for the icon that opens the app I already opened more than 6 other apps ago ;] Guess I'll stick to Multitasking Lite for the time being. Thanks!
People say don't use task killers because they waste more power then they save....which makes sense but a bit contradictory and some background knowledge would help me.
Is this mainly if you use them to automatically close certain apps or is it also if you use a task killer just to monitor them and close a few certain apps manually when you back out of them (since a few select apps like to keep running even if you never need them)
So is the stock active application widget power/battery consuming? or only if you keep 'clearing memory', or is clearing memory every now and again good? I currently clear my memory when it gets to 500mb used....is there any point to this ..performance/ battery?
And lastly, if i were to put on go launcher....could i still use active applications or should i remove it and use the go launcher version (which is quite cool)
I have Xperia Neo, its very nice mobile phone. But i have a problem, there is a lot of apps open in background. I wanna close them (cuz while i playing a game sometimes the game was stopped.). How can i do?
Advanced Task Killer should be able to help you out
thanks ..very helpful for me too
Advance task mangers are good however they are temporary as most apps that run in the background will start back up again. I found setting it on auto kill using one of aggressive setting the best option to use with the least amount of time between kills. Dont use the most aggressive option as that kills system also.
I generally just kill stuff when I find the phone to be running slowly
thank you .
i will have a try.
juice defende is better then task killers
When you have a program open, example is a video player. When I hit the home button does that program really fully close? Why I ask this is because I'll open up a web browser and input a web page. Before the web page even fully loads I'll hit the home button. Then even after a few minutes I'll load up that same browser and that page that didn't fully load will be there loaded up. I just want to make sure that when I close a program, it really is closed. That's all.
Hitting home does not "Close" or quit the program it rather puts it in the back round to fully quit it you must hit the recent apps button (Third on the left) and swipe the app away or get a task manager for those pesky back round apps.

Actually swiping apps away from recent list doesn't really close the apps. It just removes them off the recent list. Only a task manager can do that or going into settings, then apps, then force stopping it. But really,Android manages the memory very well itself. Alot of times, the way Android works, manually stopping a program will be more harm than good. Most of the time Android will just pull it back up itself therefore causing more CPU usage for that task tl bring it back. ANDROID keeps some apps semi-loaded. Ones it feels with load faster once you launch it since its already partially loaded. ANDROID is not like a PC where the processes in background will automatically slowbthings down or drain battery faster. Only certain apps that truly run in background can have that effect if too many loaded up. Whatever you do, don't use any auto memory killers or auto task managers or battery saver apps like juice defender, etc... those do more harm than good.
Unless your tablet is running with alot of lag, just try to ignore or resist the urge to keep constantly killing apps or whatever. You will see Android itself does a great job at managing it and will free up memory when actually needed. I'm still trying to do the same also resisting the urge. I just use Asus built in Task manger widget to see what's running in the background. If something clearly not needed then ill kill it. Beware though not to kill system apps or you might cause them to crash or be unstable.
A good app I came across is called BetterBatteryStats. Made by an xda member. Just type name of app in search box here in forum. That app will let you see what's truly running in the background and using up most battery or CPU processes. Has some great tips in there also in help section. IT LET me see how the Google currents app, although I wasn't using it, kept running in the background and using up processes and adding to battery drain. I would always see it pop up in my task manager although I never opened it and I have the refresh data set to long intervals. So it's basically a rouge app..lol. I uninstalled that mofo. Its a great app but runs to much in background regardless of data refresh settings and sometimes doesn't allow prime to stay in deep sleep when screen is off. Partial wakelocks, kernel wakelocks, etc...are all things you have to look over when determining what apps are causing most battery drainage or not allowing prime tl stay in deep sleep. Because they will partial wakelock n get data or whatever. It gets technical..lol learned alot from that one app. Free here in xda forums .

I was under the assumption that ICS fixed that? I suppose I was mistaken I apologize for my misunderstanding.
Demandarin, what makes you think swiping doesn't close a program? It does and its very obvious it works, just swipe then open the same program and you will see it starts over and will not be where you left off.
Try Settings > Developer Options > Don't Keep Activities. Sounds like it will fully close tasks once they are closed.

This is a very bad setting to enable if you ever have to switch back and forth between two different activities (for example email & web browsing). In general you should just leave the developer options alone.
As for closing apps.. why does it matter?
Apps that are not actively running don't use CPU and therefore don't use battery. Some apps sync information in the background, such as weather apps and email and while they do this battery is being used, however you can optimize the frequency of the updating to preserve as much battery life as possible.
In general unless you have experiencing performance issues, let Android manage itself.
If you absolutely need to turn off running apps, use the Asus Task Manager widget that comes pre-loaded on your tablet. You can use the Asus Task Manager to kill individual apps or all apps with a single click.
ON ICS, the swipe does stop the task running in the background, but I've seen where it the app may begin again, but as a background activity as almightywhacko describes.
People don't understand. Apps DON'T "run" in the background. They only run when you interact with them.

Well, it depends. Apps don't run in the background like they do in windows, but some apps do continue to run processes in the background like data syncing and what not. However, it the app doesn't do this stuff then it only holds its state.
Also, I have not seen swiping recent apps closing apps. I think it is just happenstance if an app is closed by swiping it off the recent apps. Looking at the logging and monitoring the app state I have seen no correlation between running/not running apps and the recent app list.
However, as other people said, manually closing apps in Android will most likely reduce your performance rather than do anything beneficial.
I always get mad at those stupid apps that pretend to be providing a service. They won't go away. even if kill them they just come back(like Kenny). The app that likes to bother me the most is Zen pinball. I really like the game but it is always popping up prompting me to enable openfeint which I had already signed up for. I press enable but it still does not go away.

Only if they spawn a service. As far as activities, which most people would consider to be the "app" part, those do not run in the background. It just sits until it gets killed or used.
Is it a good idea to constantly long-press home button and swipe the recently opened apps away? Is this the equivalent of "killing" the apps? I'm asking because I read that killing your apps is usually a bad idea because your RAM should always be used and it actually hurts your battery life. Is there a difference between this and going to the process manager and deleting the process?
When should I swipe recently opened apps away? Currently, I do this to free some RAM but I'm not sure if it's necessary.
Does your swipe include killing apps ? or it just removes it from recent apps list ?
if it kills , I'd say that don't swipe away important applications that you constantly use like launcher,browser,whatsapp etc
on the other hand you can swipe off apps you rarely use and which might be open like games , or other apps
you are right about swiping the important apps,it does more harm than good

When you swipe away recent apps you are essentially "exiting" the app safely where as when you use a task manger application you are force closing the application on the spot. This is not the same as "killing" the app in a technical sense what is happening is two things. The first thing that is happening when you swipe away a recent app is it kills any background process or empty processes of the application in a safe manner (Check out this section of the Android developer guide for more info on what this is about) unlike a task manger which just kills the entire application process negatively effecting performance. Second what is happening is the new API is used to tell any services of the action that is what removed so that the system can appropriate action such as starting a new process or service (For more on this see this section in the Android developer documentation). In answering you RAM question Android manages it's own memory which is why task killers once again mess this up and hurt rather then help performance. The recent application list shows what apps were recently used and clearing this will tell the applications to exist free some memory but some of their background services and tasks will still always run in the background as part of the app using some memory and battery. To explicitly and completely stop an app from memory you can go to Android built in application manger under System Settings > Application Manger and then go to the running tab and see what applications are running in the background. Overall, removing recent applications will help battery life but as previously mentioned the apps background processes will use some of system's battery and memory resources.
