hi guys, i notice in manage applications / running servises that i have many applications that they are running without i open them, and when i stop them ( forced to stop ) in about 1-2 minues they are running again, this applications is social hub, maps, facebook...
and i'am using right now (without connection to the internet) 365mb ram!!!
how can i close that programms to safe more ram?!?!?!
Thanks.
Advanced Task Killer, now that's not advised in Android!
Alternatively you can use Titanium Pro and freeze some unwanted apps, that'd save some.
PS- Also found this app,

Don't bother about it (if you really wanna bother about this, then start by learning memory management in Android/Linux before drawing incorrect conclusions)).
The RAM is used for caching applications etc, it improves speed. If you start a huge game that needs all memory then the game will gets its memory anyway.
So don't worry, be happy with your phone instead
thanks, but its normal that ram that it uses?! you how many ram do you use?!?!?!

It is because different task killer have different security policy, which allow them to show the system apps or not. So, in the lower security policy, you can see more running apps and gain more memory after kill them
i do have a question. why are you using a task killer?
I'm not having a dig at people that use them, but more trying to educate people that they are not required
"free memory" is not indicative of a healthy system in linux based machines.
please remember the way in which linux based OS's (which Android is) handles memory. Basically, if you have a heap of free memory it is simply wasted, the OS is not running any more efficiently. It is actually slower.
Here is a quick overview. Written for the desktop computer perspective, but translates over to a mobile phone OS quite well.
"Traditional Unix tools like 'top' often report a surprisingly small amount of free memory after a system has been running for a while. For instance, after about 3 hours of uptime, the machine I'm writing this on reports under 60 MB of free memory, even though I have 512 MB of RAM on the system. Where does it all go?
The biggest place it's being used is in the disk cache, which is currently over 290 MB. This is reported by top as "cached". Cached memory is essentially free, in that it can be replaced quickly if a running (or newly starting) program needs the memory.
The reason Linux uses so much memory for disk cache is because the RAM is wasted if it isn't used. Keeping the cache means that if something needs the same data again, there's a good chance it will still be in the cache in memory. Fetching the information from there is around 1,000 times quicker than getting it from the hard disk. If it's not found in the cache, the hard disk needs to be read anyway, but in that case nothing has been lost in time."

Nope, that is the reason why i have to use task killer
For me, it help me save much of battery
Since I stopped using a task killer my battery is better.
Don't use a task killer for a week and watch the difference.

yes and yes!
if your phone requires the resources, it will kill tasks that are no longer required. its all automatic. let it do it itself and you will have a much happier phone
AND better battery life, because the android OS is not continually restarting processes that your task killer deems unnecessary. I would trust the actual OS over a 3rd party app. It is designed that way for a reason (see my previous post).

The idea is absolutely right if memory is being used for apps you are likely to open frequently. ATK allows you to unselect the apps you want to keep running. That way you can unselect the ones you use the most and then use the widget to kill everything else.
I notice when I press the home screen many apps don't kill them selfs and after a while I have loads of apps running and the system starts to lag, specially when I try to run something else.
There are advantages in both approaches and I find a mixed combination (available with ATK) makes it best, although the user need to use some common sense to do it right. Killing everything means the system will be more responsive but regularly used apps will take longer to start up. Not killing means the apps you use a lot "startup" faster when you use them repeatedly (as in fact they never stop running) but after a bit the system will lag when using other apps and may need to use pagefile/swap to atone for the lack of free RAM. That causes page faults which make the system even slower.
The iphone developers aren't complete idiots for killing every app. They have a priority for system responsiveness and they did achieve it at the cost of background running apps. I like the possibility to choose what I want to keep running and kill the apps I'm not likely to use again and it's one of the reasons I picked android.
A little Offtopic to both ifanboys and ihaters:
I never owned any apple product as I think of them as over priced. That said I think the iphone has great merit and I doubt very much we would have Android if the iphone didn't pave the way. Besides I jailbreak my brother's 3G and made it multitask enabled. Now it runs apps in background and there is little diference between it and my android. Except for the extra 200€ it cost, the lower hardware specs and expensive service provider contract my brother pays for a mandatory 24 months, while my X10 cost ~65% initially and came free of any contract.

Thats what I and others have found, which is why some people choose to use one, myself included. Someone posted a link to an article last week with similar information posted here about the OS handling itself, but the comments section of the article were full of comments similar to what pco and myself have said, so it's all down to personal preference whether or not you choose to use one.
I did use a task killer for a while, then stopped. Personally my phone is better without. I have nothing except weather that updates automatically, I do it manually when I need it.
It is one of those things, just like on a laptop, everyone has different configurations and usage patterns that results will vary.

Don't apps exit when you keep hitting the back button? And for games doesn't hitting exit shut down the app?
I thought its a feature that apps don't close when you hit the home button?

The browser for instance doesn't. Same with many other. I think it's up to each individual developer to program that behavior for his app.
I got Visual task switcher and I notice lots of apps just stay running forever.
Task killer caused probs for me. A daily switch off doesnt hurt, but have run mine for 7 days and been ok. Even a bberry cant do that!

Guys, don't use home button to exit apps.
Will just send them in background.
Use the back button... this won't exit (most of) the apps but will put them in a "sleep" state so, next time when you will use it, it will load faster.
So, again, home button will put the app in background, still running.
Test it with an audio player for ex.
Or a browser... send it in background with home button and the player will still play or the browser will still have that page loaded.
With back button, after all views are "closed" the app will close too (well, put in sleep state).
I use ATK only to kill the apps i use once in a while ... the rest of the stuff, is always in memory.
My X10 has usually about 25Mb free
Actually I used ATK to kill application that need to connect to internet, and in my case there is extra charge payment. But after i used ATK I don't notice that the battery live is longer. So I ever ask someone in my thread about after ATK kill applications and so forth....
And somebody told me to quit using ATK and now I realize that the battery last longer than before.
But one thing still bother me is:
Setting - Wireless control - mobile network - mms & data (no checklist)
means: I can not access internet and receive or send mms either.
Actually I only need MMS, not internet.
May be somebody can help me solve this problem.
Thanks.
But my conclusion:
NO NEED ADVANCE TASK KILLER.
After I uninstall ATK, my phone still running smooth and the battery last longer.
May be we just need best Cache cleaner. But I still trying some of that.
@pco.vaz
I don't want to be mean, but you are wrong.
Even those iOS versions that are not multitasking enabled keep apps in memory. Leaving an app on an iPhone resets its UI state and halts its processes, but parts of the app are left in the memory. You can see the difference in loading speed if you decide to reopen it.
There were apps that could show memory usage and clean it on the App Store, but Apple removed them. You can still get them through Cydia and see for yourself how memory management on iTouch devices actually works. Basically the iPhone goes as low as 3-4 megs of free memory and handles it in smiliar way as Android.
On both Android and iOS, apps that are in background are paused after a while and do not use processor cycles. Memory they keep occupying is overwritten if needed by another process.
I do not recommend using task killer to people who do not know what they are doing exactly. Killing even simple processes often causes phone instability and drains battery faster, as others have already said.
If you feel your phone is stalled, perform a simple reboot. There are apps that run in background (in most cases you are warned about this) or are poorly coded that could cause this behavior. Other than that, inbuilt application manager is able to force close apps pretty well, if you need to kill a single app causing problems
I've read many threads on the forum with conflicting views on Cache/RAM management. Generally, I use my phone (X10MP) only for SMS, calls and some very light web surfing (if I can find a hotspot).
Currently my RAM hovers somewhere between 60-80 MB used and 70-90 MB free.
I don't know the exact about of RAM I have though.
Just want to get some opinions if there is a need for me to clear the cache in the RAM. There are many applications that are cached in the RAM which I do not use very often. These range from things such as Media, Google Playstore and a few other things.
Is it possible to prevent these applications from being cached in the RAM? Especially since I do not use them often. I'm aware of apps that can kill such cached apps but the reviews for these management apps are kind of mixed.
Secondly, I'm just trying to fish for some suggestions on QR Code reader. Anyone have good recommendations? The ones on the Market have much mixed reviews so I just wanted to get a second opinion.
Any other applications that are beneficial/essential to help the X10MP run smoothly while not sacrificing battery life?
I'm currently using nAa kernel with MiniCM7 2.20 flashed.
Browser -> Dolphin HD
Gallery -> QuickPic
File Explorer -> Root Explorer (I can't seem to attach files via email using this though.)
Thank you =)
Hey guys, Wanted to know if someone could clarify the difference between active applications, running services, system storage, and app cache. I understand that active applications are apps that are left open (usually what happens when you press the home screen to leave the app) and that closing these apps clears up LOTS of RAM. I also understand that running services are the background processes that some apps use and that closing some of these are pointless cuz they will just start back up again. My question is, are all these categories eating away at my RAM? Does clearing up Cache also free up RAM? Are apps that are downloaded on the system storage also eating up RAM or is system storage a completely different thing? Sorry for all the questions, But I am hoping someone here can give me a clear explanation or breakdown of the things I just listed. Thanks!

Hey...not sure if this has been answered before or not but im trying to figure out battery draining issues and one of things ive always used is ram optimizers...I have Android Booster and Android Assisant ....and then i also use the built in task manager to clear memory...shouldbi be using these apps or are they draining the battery by running in the background? They seem to clean up a nice amount of memory....and keep my phone running fast....just dont know much about them...

I do not think that by cleaning your RAM, you can reduce power consumption by RAM.
Actually, you do increase it. Android itself closes unnecessary applications when needed to clear memory. But, when you clean memory, either by task manager, or some custom tools, you are basically forcing applications to close and restart unnecessarily. I would say, it is additional load on CPU, and thus on battery.
For most applications, exactly startup and finish times are most expensive in terms of CPU load and battery. And most well-designed applications will not drain your battery when paused.
Reminds me of RAM cleaner programs for Windows machines, that would simply trigger excessive page faults.
while i agree with most of what you posted, there are 2 major flaws in your logic:
1. you talk about closing apps that restart on their own, but not many apps actually do that. sure, widgets, services, your launcher, communication apps and syncing apps need to run in the background, but certainly there are other apps eating away the battery, that need to be fully closed, when not needed. kies air or wifi file explorer come to mind. some of those apps don't fully close through the back button and must be killed from a task manager to save battery.
2. you say apps are paused. that is not necessarily true. many apps are capable of fully running in the background, after all, we are talking android and not iOS. we have full multitasking and apps are not generally suspended. say, you want to play a game for the first time and it needs to download more data. you can do whatever you want with your phone, open a dozen other apps, browse and listen to music, that download will continue in the background. this might fill up the ram over time, if you never close an app or apps do not allow direct closing.
there is a reason why samsung supplied the phone with a built-in task manager.
some apps are not well made and don't quit properly and need to be killed that way and killing off unnecessary apps (that won't restart) makes sense.
and let's not forget apps that get stuck but don't force close. they need to be killed as well. what else are you gonna do? restart the phone? certainly that wastes way more power than a restart of a few services.
every time you have a look at the samsung task manager or the "running" panel of "manage applications" and you use 500 something MB of ram and kill all apps, it will go down to something like 200 something, then the services restart and you are back up to maybe close to 300 (all numbers vary on your rom and apps). given that situation permanently saving 40% of ram is certainly a good reason to kill apps before you put the phone in your pocket.
I guess, then, it is best practice to kill all apps from task manager, a few times a day, especially after using several different applications and closing them. Applications that are needed will be restarted automatically.
I am not sure about running so called "RAM optimizers" constantly, though. When you are using your phone, it simply introduces more lags. Otherwise, it does nothing, if you have cleared RAM after heavy usage.

killing itself is not necessary in the 1st part.
the more the memory android uses the better the apps behave, thats how android is desinged.
if you people still want to release some memory just use the samsung task manager ot clear memory or "fast reboot" from market.
Thx for the posts...i deleted the 2 android apps for now to see if theres a difference...i will trybusing just the built in task manager for a few days and see how that goes. But for example i mainly use my phone for words with friends...facebook...twitter and instagram....when i run the built in task manager it frees up mabye 200mb of ram....then i would run android booster which would clean up another 200mb and would close stuff like facebook...and tweetcaster and so on....the built in task manager doesnt seem to pick up on and close everything it should...which is why i downloaded the others...my phone has 800+ mb available and i usually find that ots using 500 of those 800 at all times...i wouldbfind myself constantly closing stuff with the optimizers...but like you said...they just open up in the background again anyway. Im rooted and have got rid of all the safe stuff to get rid of and the funny thing is i still dont see much of a difference in ram consumption...i think of ram as important cause it keeps things running smooth with no lag...not sure what to do i guess...ill try it like this without the optimizers and see how things go and download them again if i get bad lag...what i really need is a actual list of my phones internal software so i can get rid of the rest of the unneeded system files...ive found similar lists..but never a list of my actual phone...theres certain stuff running on my phone that isnt in the lists ive found so i left them with the worry that i may have to reinstall the rom if i delete the wrong thing...im also a android noob...only 2 months of using it so far so ive got tons more learning to do...thx for the opinions tho...keep em coming if you got em!

On average, at startup,
- Clean Master shows:
> 50% RAM
> 70% Device Storage
> 20% SDcard External Storage.
- Titanium Back shows:
> 500MB free RAM (of 2.11GB)
> 4GB free Internal+Media (of 10.9GB)
> 50GB free ExtSDcard (of 63.8GB)
Starting with these numbers, the device freezes after a bit of usage of the Swipe (Nuance) App. But I recently played with a 78 year old banker's GT-N7105, which was 20 times faster than mine, while running the same Swipe keyboard App: "My nephew geeks around a forum called xda-developers!"
1. In general, what's the relationship between installed Apps and RAM usage? Sometimes when I kill an app it frees up a bit of RAM, sometimes a lot and sometimes nothing at all.
2. Do installed (but not opened) Apps take up RAM space just by sitting in my Apps drawer? Should I uninstall all the Apps which I downloaded because "one day I might need it" and never used them or are they harmless (RAM wise) if I don't open them?
3. Do Apps which have been launched and now sit in the background take up RAM (as in Windows)?
4. Is there any difference between "fereezing" and "un-installing" an app as far as device operation speed is concerned?
5. Do I need to make sure that Apps don't start up if I don't need them (Google Play Services, Google Play Store, Goggle Translation, YouTube, Video Player, S Voice, Picasa Uploader, Nearby Service, Nearby Devices, SNS)?
6. If they eat up RAM, how do I make sure that they don't self start? Android Assistant App?
7. If background open Apps eat up RAM, is there a way to kill them automatically once I open a new one without loosing the cahced data which i might be using?
Thanks in advance for your time and expertise.

Ugggg I hate this app lately! Just spent ten minuets answering all your points fully and it gave me stupid permission error! Even wrote a nice analogy about ram and libraries...forgive me if I'm brief now
Sum it up
Poorly made apps or ones that need to stay in the background to operate fully or spy on you stay in ram, many don't, dump bad and seldom used apps, stay away from task killers, if you need one use watchdog, see what's actually using cpu, better battery stats or cpu spy can help too. Freezing is fine, v6supercharger can help you, setting background process limit in developer settings can help
You have a nice snappy phone, get rid of junk and use nice roms and you'll have no issues

I only got the jist of it but I didn't really understand... any chance to try again, when you have more time on your hands?
There are 3 aspects that make up coffee flavour: the beans' quality, roasting and preparation.
Beans (origin, ripeness, homogeneity, dryness) and roasting (tempreature, duration) are, for now, out of your reach. But preparation isn't.
Most infusion's preparation depends on 3 basic parameters:
- temperature
- time
- contact surface.
Threfore brewing time and temperature and the beans' grind size (and also the grinding method) will influence the coffee taste: the greater the time, temperature (up to 95°C) and surface the greater the organoleptic proprieties' transfer will occurr. Which does not necessarily mean the better taste... more on that in the next lesson.
Organoleptic properties are the aspects of food or other substances as experienced by the senses, including taste, sight, smell, and touch, in cases where dryness, moisture, and stale-fresh factors are to be considered.
