I think many of us are using some kind of task killer. BUT, I find task killer sometimes cause more problem than it solves. And sometimes it doesnt really increase free RAM.
What I did was create a simple app to force Android memory manager to free RAM (by unloading tasks based on its own logic). This way you eliminate 3rd party task killer wrongful termination of tasks such as those active ones required by widgets etc.
This app just basically starts and creates a huge heap (forcing Android to free RAM) and then closes.
(You may still see this task linger in memory after you run it, but it will be unloaded the next time you start other app. You will see your free RAM increased a lot)
====Edit
You May not see free RAM increase immediately after running. You will see RAM increase a lot a bit later after you have started other app (which forces BfreeMem to be unloaded from memory)
Tip: Just put a shortcut on desktop. Click it when your RAM is low (<50-60Mb) and it will do its job. Dont run it when your free RAM is above 90Mb.
I'm trying it

You have to wait for BfreeMem to be unloaded. (If you are impatient use a Task killer to unload it and you see it frees up lots of RAM.
Basically BFreeMem is a very bloated. When it starts it force Android memory manager to unload other tasks to cater to its RAM requirement. After that if you start other app, Android mem mgr will unload Bfreemem thus freeing huge chunks.
I tweak it to works best if your free RAM is around 50-60Mb. When I run it and when BfreeMem is unloaded later, free RAM goes up to about 100Mb.
btw: this app requires no permission so your data is safe
AutoKiller is a much better alternative.
The concept sounds correct. Not entire sure if it will work in practice.

My purpose is to have something that does not circumvent Android memory manager which keeps track of tasks and their stats. It knows better what tasks are best to kill based on their usage/last access/active state/priority. Furthermore, if Android memory manager kill a task due to low memory, it will save the state for that task so that the next time that task is used the saved state is restored.
3rd party task killers sometimes mess this up by killing tasks which are actively use (resulting in those tasks being restarted just after being killed leading to wasted power and more lag) or killing dependent tasks such as those used by widgets without saved state causing widgets to malfunction.

I am using it. It does free up RAM. Is it useful? Depends. If you have lots of active apps (widgets/service etc), those freed RAM is filled up soon as Android restore back those "killed" tasks. Not much gain here. On the other hand, if you have lots of zombie apps lingering in memory then yes. The extra RAM does give a boost to the next app you open
AutoKiller is less of a task killer and more of a memory manager. Sort of like what your app is trying to do, but much better. More information: http://andrs.w3pla.net/autokiller/details
Your concept is good, but having an app that continually increases ram usage will waste battery. Then having to kill that app manually in order to free up ram is tedious. Just my 2 cents.
The new task manager in Touchwiz has a function to manually clear ram any way, which works great.

OK. AutoKiller is changing Linux configuration. Unfortunately, it needs root.
I have used the TouchWiz TaskMgr clean Ram at safe level - it still messed up my widgets (Beautiful widgets, weather & toggle)
Bfreemem app does not continually run or increase RAM usage. You just run it when the free RAM is low (or close to threshold). At this low RAM level it just knocks other tasks out of RAM. btw: You should NOT run it when you have huge amount of free RAM. You should run it when RAM is low like <50Mb.
You dont really have to kill Bfreemem task manually since it will be quickly unloaded by the Android memory manager when RAM is required since its state is finished.
JUst put a shortcut on the desktop and click it when you feel RAM level is low and it will do its job.
Can it be used with autokiller?
It could be also automated to check if memory is low, and automatically kill applications. Battery drain would be present in that case tho..
Never has the default task killer from samsung messed up my widgets including Beautiful weather, I tried using task killer and never saw the benefits of it since andriod automatically keeps 40MB of free ram...

Personally, I dont use task killer. Not sure whether Autokiller kills tasks physically or just adjust some running config. Just have a feeling task killers (those that kill tasks physically) cause RAM leak. For example when my phone reboot, I can see at least 12 tasks (in Advanced Task Killer) and free RAM is about 95Mb. If I physically kill those tasks, my RAM may temporarily goes up to 130Mb but sometime later free RAM drops to 50-60Mb and there were no more tasks to kill.
When I use Bfreemem, my free RAM fluctuates betw. 60-100 Mb and I can still see all/most of those tasks that were there just after boot-up.
If you have one of those scheduler/timer app, you can just use those to schedule Bfreemem to run regularly. (I can build another timer app to schedule)

I notice the phone start lagging when there are less than 100Meg of available RAM on both 2.1 or 2.2 SGS.
Questions....
1. How do i make sure there will always be min 130 available when not in use?
I'm currently using Froyo Task Manager, ATK and SystemPanel together to make that happen manually. A better suggestion or use of them will be appreciated.
I also tried MemoryPlus and Taskkiller (The red android logo)
2. There are so many background service running some of them start with com.samsung.... (what are these?) do we need them?
3. Why some Apps always run without us telling them to run, or ask us to give them to permission to run on background at will?
ATK
In ATK in settings you have auto kill level, which is disabled on default.

I'm using JPC, ATK autokill will not able to kill at a system level like SystemPanel, so after a day of active use, the memory will still continue to reduce as some of the background service start consuming more and more memory or run more background process. E.g. Touchwiz from 17 Meg to 25 Meg.
So at the start with ATK, i will have 130Meg, after a day of active use i left with 80Meg. With Apps killed.
I use autokiller set to aggressive. memory left 152mb

What is the point of having memory if it is constantly empty?
Think about it this way...If you had five friends at your house and you have five chairs, do you make 2 or 3 of your friends stand so there is always empty space or do you let everyone sit down and worry about something worthwhile?

True, upto a certain point... I don't think you need to have at least 100 or 150 mb free but it DOES seem to help to not let it get down to like 30mb...
For me:
-JM7
-animations off
-voodoo lag fix
-minfree manager set to preset agressive.
minfree manager customizes the android memory management system.
I love it this way, No lags when starting the Phone (DIALER) or anything else. The dialer annoys me the must, this must be lag free, if i want to dial i want to dial right away.
Btw, I think you have made some wrong assumptions about the Android memory management system, as mentioned, unused ram is wasted ram.

Agreed but I have never seen my Galaxy with free memory that low and I don't use a task killer. Of course I don't often have more than 3 or 4 apps running at the same time
This is not about letting ram do nothing.you surely don't wasn't your ram get used up by programs you don't want while you had no hand in this.All those services running I don't want.badly written programs that are hanging out in memory instead of closing.at least in symbian an app closed when you exited.
Why would you have 100MB free ? Do you have any application that needs 100MB to run ?! The android system already has enough memory to run so even if you could have 200MB of free memory you phone wouldn't run any faster you would just be able to lauch around 20 apps at the same time.
Read this:
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
Linux however isn’t generally affected by this. While I admit that I don’t know the architecture and reason for this… linux will run the same regardless of if you have 20mb free memory or 200mb.

Dunno, I just noticed that one time my phone was VERY sluggish and memory free was around 20mb or so. Cleaning it up did seem to help (unless one of the programs killed was causing the lag of course).
Ah well... Whatever people choose right?
You guys can argue all you want that free RAM is a waste of RAM....
But it is a fact that the SGS runs much slower when the free RAM is low. This is the experience of all the SGS'es I have tried and my own as well. At least this is the case when running 2.1. I have not tested anyone with 2.2 yet.
It s starts to lag when memory is below 40 mb. So when it s low and you start an application it starts to lag. I set it to 50-55-60 and got hardly any lag. No need to keep so much free ram

Which ROM are you using? as the low memory killer level for background apps is set at 40M which means you should have 40M free all the time or it will start killing background apps. This is also why task killers are useless, free ram is wasted ram for android.
I never had the experience that more free RAM is faster, perhaps with the stock rom but JC and upwards are all good by default. Animations off + Oneclick lagfix (or another) and the phone stays totally lag free.
Being an android user for 1,5 years now i'm very confident Taskkillers are useless except when an app is stuck. I've had periods where I used them allot but the phone only gets slower as the killed apps have to be loaded into the memory again.

Provided you are not expecting anymore friends. The problem happens if all your 5 friends are happily seated and along comes 2 more friends a-visiting. So you have to now move 2 inactive (for want of a better word) friends out of the seats so that you can accommodate the 2 new ones. This takes time. So why not move these friends out as soon as they become inactive so that the space is readily available when someone comes calling?
Try to have a read about garbage collector before argueing about free memory.
The more you try to have a large amount of memory, the more you will need major GC (and during major GC all activity is frozen).
If you let the system manage memory, it does minor GC as needed when it reaches min memory waterline (seems to be 50Mo on SGS).
Let the system do its job.
Get rid of task killer.

I completely disagree. OK, it is better to use memory, but the android memory management is extremely inefficient since it does not know which foreground and background processes are important to the user and which are not, even though it tries to figure that out. Since the Galaxy S does not allow the system to use the full 512MB of memory, this can be a critical factor. And the Galaxy S definitely lags massively when less then 70 or so MB of free RAM is available this is definitely a fact.
The biggest problem is that you cannot manually close apps and only have multitasking access to the last 6 apps used. If you use 7 apps simultaneously, the 1st app still consumes memory but you cannot even switch back to it. And there are so many useless background processes, starting up over and over again and consuming hundreds of MB memory if they are not killed in regular fashion.
Who needs gesture search, amazon mp3, layar, and all the samsung crap running in the background all the time. If you only have 10 such applications and each of them only consumes 15MB of ram, 150MB are wasted for nothing.
Every second market application registers itself as autostart on every boot, so to use a autostart manager is also mandatory.
Since everybody can easily develop for Android the application quality and resource efficiency is not always perfect. So in my opinion Android needs a task manager, this is why even Samsung integrates such a application.
Using a well configured ATK (set to ignore system applications, widgets and apps frequently used for multitasking and killing every else on screen off) and autokiller (strict setting) in addition to Autostart Manager (had to remove 40!!! useless apps from automatic startup) and lagfix, the SGS runs perfectly smooth.
Been using Quick System Info PRO for the past few days, and am truly impressed! Multi-functional as a task manager to close / ignore running apps...cache cleaner keeps system from bogging down. Process tracking / cpu usage tracking. Tons of system specs available to view, etc. Uninstall apps directly from this as well. Find out exactly what apps start on boot up, and trim as you see fit.
I know memory is at a premium for us Archos IT users...I encourage you to check this app out. It's a little more complicated than your standard task killer, but truly helps trim things down. Best of all, it's free! Option to donate to disable ads, I donated just cuz the dev blew me away with this app!!
Enjoy, and please offer up your own opinions!
How do u change what programs run on startup? I downloaded it and its good but I don't see that feature.
Task killers (apparently) shouldn't be used on Android (generally... there are always exceptions)
If an Android app is created properly, it shouldn't be eating away at the RAM, and Android will free up what it needs.
If it killed everything, then the multitasking feature will be as useless as Apple's

While I certainly agree with this...do you own an Archos? Task Killer is almost necessary for the Archos 70it. Until they increase memory allocations, the need to minimize what's running at startup or any given time is absolutely needed.

So what are you using your tablet for? Reading ebooks? If you have more than 1 user process running at a time, in addition to system processes it gets bogged down. Android is great at multitasking...256k RAM is not. I have my 70 trimmed down to skinny, having removed some bloatware apps. Normal is around 55-60% of RAM usage during standby.
If I decide to break out a game, like Dungeon Hunter or another system hog...I run into occassional FC's if I haven't freed up some RAM. A TASK MANAGER helps me select the things I want to shut down to free that RAM for an app / process that I choose to run. Stop confusing TASK KILLER with TASK MANAGER. (Was a typo in my response earlier) Yes the app allows me to kill tasks, the difference is...I'm killing what I CHOOSE to kill.
PS - I haven't done much to alter start up apps thru this Manager, just have used it to trim fat and gain control of my RAM usage.

Play games, read books, video, music, etc. Just about anything you can do with it.
I also used to have a task killer and decided to install Watchdog which works in a different way. Works a lot better that all the rest of the task killers I have used and did not have any issues. Apps run smooth even if I have more than one running.

I recently upgraded from a hero which wad heavily tweaked thanks to this forum.
Now that I have tweaked the DHD to use evolution HD (great btw), I have a question about task managers etc.
People have said the built in management is much better etc etc. But how does it know when I have finished with a program? If it does not have an exit now button in the app will it effectively keep running? I used to use task killers just to kill everything after I have playing with the phone. Is this not needed?
Thanks for reading!

just leave it then
as you've got an DHD, you've really got enough RAM
so: if another process needs ram and nothing is left atm, android closes the one you left "running" some time before, etc..
don't use task killers...the integrated android "feature" does its work..for sure!

No it's not and this is where the problem arises, if android thinks an app is required, it will respawn it after you have killed it using uneccessary cpu cycles, and it will do this repeatedly every time you kill the process. As long as you haven't got a rogue process eating all the cpu cycles when it shouldn't task killers are not required.
Dont listen to people who say "uninstall your task manager it's not needed" its absolute crap, yes it is true that android's own internal memory manager does a great job on its own and yes having a task manager that kills task on some kind of schedule is just a waste of battery and resources, but if you need to run any kind of task that is resoure heavy it's imperative to have a task killer to free up some memory or that task could take forever. its also useful for playing demanding games ect. thats just my opinion anyway

Which benefits you how? Android isn't windows it doesn't run smoother because it has huge reserves of memory sat around unused, yes if you kill everything and leave your phone on idle it may well free up a huge amount of memory, but start using it and it will respawn important processes. For the undecided her'e some further reading Lifehacker, geekforme, Androidspin, Infoworld, talkandroid, tested and the last word to Google.
Even Windows doesn't run smoother if there's lot of unused RAM. Even though the makers of those RAM "optimization" tools will tell you different. RAM is there to be used. Free RAM is like having your money in a sock under your bed instead of getting interest from it.
On my DHD Android will start killing background apps when the free RAM drops below 40 MB. And what more do you need? Why is 150 mb free RAM better than 40 mb free RAM? If an app needs more than 40 mb the missing RAM will be freed up almost instantly. I doubt anyone will notice. And almost no apps use 40+ RAM anyway.
And to those that are absolutely convinced background tasks eat their battery. That's wrong in 95 % of all cases as well. A background app that does nothing also uses no CPU = almost zero battery usage. So no harm done. And a background app that does something mostly does so because you the user told it to do so. What eats battery is the display, setting the brightness to 25 % or so really help. But that's offtopic...

yeah i understand that, but what im saying is SOME application and games (av suites, emulators eg psx4droid and fpsce, games like dungeon defnders ect) they generally require more ram to operate than the minimum android will leave free, so in thoes curcumstances, it is usefull to have a task killer to free up enough ram for thoes tasks to run optimally, i did a experiment the other week, and it took my av suite 17 minutes to do a full scan with no memory optimisation and 11 minutes to run after using a task killer, are you seriously telling me using a task killer once or twice a day will use more battery than leaving the phone scanning for an extra 6 minutes? also all these sites you quoted, i agree having a task killer on a scheduled auto-kill basis is a waste of time or battery, but people came to the conclusion not to use task killer 12-18 months ago when there were very few high powered devices and resource heavy tasks, now there are more and more apps that require a large amount of ram to run optimally..

exactly, when people started saying dont use task killers, devices had very little ram, but on the other hand applications required very little ram, things have moved on now, and with more powerfull devices come more powerfull applications, and although i agree with having a task killer on an auto-kill schedule is a waste of time, i think its useful to have one for thoes time you want to run a resource hungry app, but you know like they say YMMV
Thanks for the replies, it makes sense now.

Can anyone explain the amount of RAM that this phone is suppose to have?
The specs for the phone lists 768 MB. However, the total memory that comes up is 617940 kB.
Thanks.

where are you finding this number? i am at 758 MB. since i have a bunch of apps installed, that would seem about right.
How are you guys getting so much free ram? When I check on Task Killer, whenever I kill all the apps I'm not using it usually shows 358 mb ... and programs I'm not using automatically keep running (i.e Maps).
hmm maybe im not checking the right place? i'm getting my 758 mb number from settings--SD and phone storage. the internal phone storage tells me 758mb.
on an unrelated note though, you shouldn't use task killers. they are considered by most to be more of a drain on your battery life as android is already setup to manage closing unused apps on its own.
Many people use the term "memory" to mean system memory as well as storage. I try to avoid calling system storage as "memory" and tend to use "storage" instead, or refer to the type of storage.
Total ram is around 768mb. Part of it is reserved (not sure why, possibly for filesystem caching) so around 603mb is available. For this platform that is a healthy chunk of RAM to work with. Even with my hefty usage I have ~126mb free.
Internal storage is something like 2gb, with it partially consumed by the Android install as well as NAND configuration adjustments for reliability which cause some of the storage space to be consumed through hardware (there's an excellent explanation of this somewhere, don't have a link handy), resulting in about 1.1gb being available. I have 103 apps installed, 523.5mb of the internal storage used, with 638.8mb available.
There was an excellent tool posted on xda (http://forum.xda-developers.com/showthread.php?t=1066060) called Android Optimizer that gives a lot of good information about memory, storage, cpu usage, etc. I'd recommend checking it out. It's not available on the market and it is a little buggy so use it with a bit of caution if you choose to use any of the optimization functions.
cool. thanks for the explanation nimdae!
There have been so, so, so many posts on this topic that I will not rehash them all here. Instead, I will ask a simple question: For what do you use all that free RAM?
Ask yourself that question, and be serious about it. I think you will find yourself uninstalling your task managers and memory optimizers before long.
Edit: to avoid unnecessary discussion, Watchdog is in fact neither of those, and I would highly recommend it as the only memory app you will ever need.
Edit 2: the total RAM displayed is the RAM that is actually available to be used by anything the user may want to run. As a poster earlier said, the system reserves a certain amount of RAM for its own use to keep important processes moving along. The reserved RAM is not available, and so doesn't appear in total RAM. Unless you want to uninstall the OS. Then you could have access to all 768 MBs.
I would like to reiterate why you should not use automatic task killers.
As of, I believe, Android 2.0, the garbage collection and memory management was significantly improved. However, this was not a new system in Android, it always existed.
How it works:
If you haven't noticed with Android, when you leave an app, it doesn't close it unless the app specifically does something to end the process. This is by design. Android allows the app to remain in memory. Frequently used apps will load faster with this design. A "task" that is not killed and is in the background ONLY consumes memory, it does not "run" (in Linux terms, the process is actually in a "stopped" state so the task can't do anything anyway). Only a "service" can run in the background. Most apps that have long running services have lightweight services.
If an application loads that requires more memory than is available, Android will examine backgrounded tasks for candidates to be killed to free up memory. This makes it so as many tasks as possible can remain in memory for better performance. In understanding this, you should know that if you have a large amount of memory, and memory usage is high, this is a GOOD THING. With the amount of memory in the I2, there is a lot of breathing space for this.
There is one other case where a backgrounded task will be killed: if it has been in the background for a certain period of time without being brought forward. Killing a task to free up memory to load another task can actually be a little cpu expensive (but not THAT much) so this can make it slightly easier.
Please note that backgrounded tasks WILL NOT contribute to battery drain. Only tasks at the front and services will. Killing your backgrounded calculator will do nothing for you other than free that small amount of memory it uses. Used memory does not contribute to extra battery drain as DRAM refreshes happen on ALL cells anyway.
Background services can also be made candidates for being killed. If an app needs more memory than can be made available by killing backgrounded tasks, then services become targets to be killed as well.
Automatic task killers cause a couple of problems. A less major problem is you lose that one benefit you get by keeping tasks in the background: performance. I don't just mean how fast it loads. If it can bring a backgrounded task to the front from memory rather than load from storage, you remove extra processing to load the app, including storage access, that contribute to higher battery drain. The other problem is a poorly configured task killer can break things like notifications.
Managing your services is always a good idea. Having a lot of services running means background processes that are capable of contributing to battery drain. Additionally, there are apps with misbehaving services (services that consume resources or use features they shouldn't). While I'm against automatic task killers, using something to monitor and manage services is a good idea. Just always keep in mind the implications for killing a service: it may affect a feature to an app that you would rather not impact.
Excellent explanation nimdae! Task killers are the devil.

Remember: I'm not saying don't manage things. Poorly behaving services are the #1 cause of high battery drain (at least on non-LTE devices), and this will be even more problematic when you overclock.

I tried not using them and I get better battery life with them...I use it maybe 3 times a day after heavy multi tasking. It's to each their own..but I see results for it..like 5 extra hours.

If you get that much extra, you have a misbehaving app. Better to get the app developer to fix it or find an alternative.

I use a task killer only to manually kill an app that freezes or something. Its easier than going to manage applications. I have the autokill disabled.

CyanogenMod (maybe other ROMs) have a feature to kill a frozen app by holding the back button (long press, whatever). However, this can also be an annoyance on systems where for unknown reasons it registers a long press on a tap (my eris did this a lot).
So i saw many posts on which people have asked as to which task killer should be used !
and then i stumble upon this site which provided me the details,

Android Doesn’t Manage Processes Like Windows
Most Android users are familiar with Windows. On Windows, many programs running at one time – whether they’re windows on your desktop or applications in your system tray – can decrease your computer’s performance. Closing applications when you’re not using them can help speed up your Windows computer.
However, Android isn’t Windows and doesn’t manage processes like Windows does. Unlike on Windows, where there’s an obvious way to close applications, there’s no obvious way to “close” an Android application. This is by design and isn’t a problem. When you leave an Android app, going back to your home screen or switching to another app, the app stays “running” in the background. In most cases, the app will be paused in the background, taking up no CPU or network resources. Some apps will continue using CPU and network resources in the background, of course – for example, music players, file-downloading programs, or apps that sync in the background.
When you go back to an app you were recently using, Android “unpauses” that app and you resume where you left off. This is fast because the app is still stored in your RAM and ready to be used again.
Why Task Killers Are Bad
Proponents of task killers notice that Android is using a lot of RAM – in fact, Android stores a lot of apps in its memory, filling up the RAM! However, that isn’t a bad thing. Apps stored in your RAM can be quickly switched to without Android having to load them from its slower storage.
In summary, you shouldn’t use a task killer – if you have a misbehaving app wasting resources in the background, you should identify it and uninstall it. But don’t just remove apps from your phone or tablet’s RAM – that doesn’t help speed anything up.
Empty RAM is useless. Full RAM is RAM that is being put to good use for caching apps. If Android needs more memory, it will force-quit an app that you haven’t used in a while – this all happens automatically, without installing any task killers.
Task killers think they know better than Android. They run in the background, automatically quitting apps and removing them from Android’s memory. They may also allow you to force-quit apps on your own, but you shouldn’t have to do this.
Task killers aren’t just useless – they can reduce performance. If a task killer removes an app from your RAM and you open that app again, the app will be slower to load as Android is forced to load it from your device’s storage. This will also use more battery power than if you just left the app in your RAM in the first place. Some apps will automatically restart after the task killer quits them, using more CPU and battery resources.
Whether RAM is empty or full, it takes the same amount of battery power – decreasing the amount of apps stored in RAM won’t improve your battery power or offer more CPU cycles.
hope u understood!
words of wisdom by fellow-mates
go into settings - apps and see how many running apps you have. now go to cached apps and see there, how many apps there are. you see? nearly 50% of those apps discovered by you in the processes are apps that you didn't opened ever but they are still opened and running. why? because that's how linux manages its resources. instead of having free ram for no use (what's the point of having 14gb of ram when you only use 1gb), linux fills all the ram blocks with useful apps or apps that you are running frequently so that when you call that app, it will bring it on the screen almost instantly. this my friend, is called multitasking.
and no, you are wrong. if you use a task killer killing the apps every 10 minutes, the cycles the whole system does - opening again apps and caching them, task killer closing them - results in much more functions done by CPU => more battery spent. even if you say that the battery life its the same, you are wrong. when using a task killer IT MIGHT drain your battery with 0.1% per hour. it's not that much, but IT EXIST.
oh and yeah, one thing: android has its own task killer. that's why you don't need one app to kill your other apps. because android its doing it by itself. if you don't believe me, strip down one kernel, open the init.rc file and find the values for task killer.
I understand this response, but I don't believe it. Task killers has always helped me in every matter. Even on a computer it helps greatly.
Conclusion: I noticed the same battery life using a Task Killer, than not using a task killer.

I'm using task menager when is needed, and also I'm using custom system memory tweaks, it makes my phone running faster and smoother some apps knows to stuck and they keep the phone from entering deep sleep, and that drains the battery, so if you know what are you doing use task menager and customize when what apps the system should kill
