How do I free up RAM for my Samsung Note II LTE GT-N7105 on stock Android 4.3, rooted?
I am an Android retarded user looking for a patient teacher who will walk me through the Android RAM mysteries and answer a few question and, in exchnage, I can teach about the secret world of Traditional Neapolitan coffee infusion: home roasting, grinding, preparation and... savouring or, alternatively, Home Theatre! Your pick!
Smiles!
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

@demkantor
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.

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."

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
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!

Jesus. There's a huge panic now because the variant has 2 gigs of ram...
http://www.androidcentral.com/ram-what-it-how-its-used-and-why-you-shouldnt-care
You actually have more free, but the android has a lot of it saved for caching, etc. For example, Facebook takes 40 mb, but when I open it only like 5 or 10 mb of the ram shown as "available" is taken away because parts of it are actually open already.
But yes, if you root it, and a developer adjusts the Minfree to a large amount you will have more free but your phone will probably be slower.
Folks need to keep in mind, that keeping RAM free as you would with a Windows based OS, is NOT ideal in Android. Android uses RAM completely differently and it is perfectly okay for your phone to make use of RAM, even for apps you are not currently using.
There's a fair amount of documentation out there about this - do some Google-fu to deep dive further.
Actually I ask because when I was trying to send a picture in whatsapp it kept sayin "try again" but when I closed all tasks in multitask the picture did send. So I'm guessing it is a ram problem.
Also take it easy on Mr. This is my first android phone, I've been using iphone since the 3g and don't know nothing about android..... yet
Sent from my GT-I9300 using XDA
You don't really want to much free ram. If there is to much free ram it means apps are not going in to cache witch will mean really slow app loading times. 200-300mb free is ample for new apps to run, if the OS needs more then its auto memory management will come in to play to free up more if needed, android is a very smart peace of kit
Sent from my HTC One X using Tapatalk 2
if anyone were to choose pre-caching order for faster load times ( usually just by seconds than non-pre-cached) to no random force closes because there is more free memory, they would chose more free memory.
but since the experts have already said android memory doesn't work the same way like windows does, then the best would be a balance between cache and free memory. right? right. that's where official updates and dev fixes come in.
It 'just a habit of many displaying applications in the background to go on the Android Market and install a task killer for fear that some application in the background throughout the battery consumption and slow down the phone memory consuming.
First Step
Android is the son of Linux and not Windows, Windows programs make sense that clean and optimize your memory, not in linux and behaves the same way if you have 10 or 100MB of free memory.
How to manage Android applications
Android applications and processes have defined 3 stages:
1) Running
2) Break In
3) Stopped
Each application runs in its own process when Android starts the process need to be made and ends when no longer needed, it lives in its own world and its code running is isolated from the rest with a Virtual own machine, it is assigned an ID whose permissions are visible to the user and 'application.
If an application needs to share files with another application creates a unique ID to save memory with a single Virtual Machine she shared.
Services are active as long as they need as well as activities that require the data connection and every process of Android. To understand whether an application or any process needs to connect and see if there are updates that it is active so that makes this operation.
It is not good or terminate these operations because the process will start all over again immediately active or when we are going to open an application it will take longer to open.
All processes are terminated when there is no longer needed or when the memory required by other processes.
If a user leaves a task for a long time, the system deletes all activities except the root, and when the user returns to the task it is like you had left.
An application is running when in fact you're running and is the first system plan
When it is no longer at the center of the 'attention but can still be visible is paused and can be killata by the system in case of need for extreme lack of memory
Finally, the application is blocked, but retains all the information is no longer visible on the screen and is in the background, can be killata from Android for any other activity that requires memory.
Summing Android is designed to kill the tasks when
You need more memory
They finished their work
Are not used for a long time
Kill process "by hand" can lead to side effects such as non-receipt of messages, slowdowns, crashes, etc. widget
The majority of applications closes with the BACK button and in any case by pressing the HOME Android close the task after it has been in the background for a certain period of time.
The majority of services running in the background using very little memory when they are not doing something so all other processes (reporting, etc.)
Domada: But why do I open google maps, facebook etc. mail.
These programs are not actually "open" if you notice are all programs that need a network connection, when you turn on the phone they do nothing but check for updates and notifications and then close.
If these activities killiamo happens that most of them will re-open to start all over again or take longer to open when we need them, or worse, will not give us accurate and up to date or will not work properly as well as make a lot more processor.

The majority of services running in the background using very little memory when they are not doing something so all other processes (reporting, etc.)
Domada: But why do I open google maps, facebook etc. mail.
These programs are not actually "open" if you notice are all programs that need a network connection, when you turn on the phone they do nothing but check for updates and notifications and then close.
If these activities killiamo happens that most of them will re-open to start all over again or take longer to open when we need them, or worse, will not give us accurate and up to date or will not work properly as well as make a lot more processor.

I know I'm likely to get criticised by some for saying this but some of us have to use task killers.
My phone has an average of 140 mb free after it boots up. Add to that apps that stay in ram even when you close them and you can have as little as thirty or fourty mb free.
I've seen apps such as facebook and tapatalk, and even some games, taking up ram even though I don't want them used once I exit from them...and when my phone gets to around fifty mb free or less it can get slow and unresponsive.
A quick kill of un needed apps makes the os perform as it should again.
It's nice to say android clears up ram as needed, and it does, but try playing a decent hd game when your ram is low and, unless you kill some apps first, you're left with a black frozen screen while it tries clearing some ram. In some cases your phone can be unusable for a while, on mine when this happens the capacitive buttons stop responding to keypresses.
Now on ics with 1 gb ram this isn't an issue but for those of us with less ram and / or an older os it is.
Ideally we could configure non system apps so that if we don't want them in ram when finished with them then they cannot auto restart.
It is a simple fact that two identical phones will perform differently if one has lots of free ram and one has most ram in use, I use an on demand task killer so that apps that stay around on exit can be stopped from eating ram and slowing my phone down so for me a task killer is not pointless specifically because it frees up ram so that something memory intensive can be run without slowing my system while android tries to make room for it.
So while I agree with the theory, in practice task killers can be useful or at least on demand ones can.

I agree with how Linux handles its applications. I switch between WinXP and Ubuntu and the overall way tasks are utilized are similar, but linux does a better job at handling running applications. On windows i have Chrome open and with 9 tabs open im hitting 1.5 gb ram used. Same situation on linux i find myself hitting around 500mb of ram used. Im sure this applies to android as well.
On a side note i find that people who "Kill Tasks" are just running them because they can and are usually fixated on seeing a large amount of ram free. It just adds another reason to stay on their device. Just my opinion.
An alternative to task killers for rooted devices are apps that blocks app from running at triggers so nothing is killed at all; the apps don't run.
Eg: the autostarts app.

I use one to make sure my phones already low ram does not drop so low my phone becomes slow, which it does when you get to even just fifty mb free ram left. And to kill those applications which do not exit properly.
On an android phone that has 512 mb ram if ram gets eaten up the phone goes slow, and I know it is not just me because other users with similar setups have same issues. So I think it is too general an assumption to say we all use task killers for say a cosmetic rather than practical reason though I'm sure some do.

Unfortunately this only stops apps auto starting at boot and once you have used an app and exited it, a lot stay in ram.
Some restart when killed some don't but when your phone is on permanently as many are, having low ram can quickly be a problem.
I think part of that is the phone manufacturer as 512 mb ram, with just 140 mb free at boot, is rubbish on a dual core 3D phone but whatever the cause I find killing tasks helps make phone run better.

I used to kill tasks when i was on Android 2.1 an 2.3, but since 4.0 i feel my phone gone strangely fast, and i don't need to use task killers anymore. Phone is LG GT540, so...

I used to love my gt540. Didn't know you could run ics on it though, good phone for the price but didn't like the resistive screen though the phone itself can take some serious punishment and still keep working.
I love lg for their build quality, pretty hard to break them with dropping etc, but unfortunately they do bad with the software side.

Good topic, I don't like the task killer!

In general, yes task killers are bad. But occasionally it IS necessary to kill an app. Sometimes an app will freeze. Then it needs to be killed to be able to use it again. But you can easily just go into Settings > Applications > Manage Applications, find the app and then Force Stop it. So there's no real need to have a task killer. Although I do like to have Watchdog on my phone, as it shows the amount of available CPU cycles being taken up by each app, so you can make sure background apps aren't using too much CPU. (It does also show RAM usage, but it sorts apps by CPU usage, by default at least).
Linux has nothing to do with the management of an application, the applications under Android are sandboxed in java and there is this dalvik machine that takes care of everything.
I don't get why people keep mentioning this kernel over and over, also for the biggest part of its history Android did not use a real linux kernel with vanilla flavour, only recently the Android kernel was merged with the linux kernel mainline.
This is one of the very first Google video about Android http://www.youtube.com/watch?v=Mm6Ju0xhUW8
edit: In this series of videos there are also references to memory management and app management.

You are right
I do the same thing
In cm9 you can enable auto close apps with long press back button
So I don't need a task killer

Well guys, i always listen about the ram used in android is different than windows..
My first question is, why RAM is like 90% used, the phone become slower???
My second question is, Why 99% of apps are always started with phone, when enter in Applications section, and see Running apps, you see millions of apps, or when you enter like, Calculator or Torch or another app details it appears Stop.. WHEN I STARTED IT?
Im now user of Galaxy S Duos, when i have Motorola Atrix using a custom rom named "Neutrino" my ram, after flash it was 80~90 and here in Galaxy S Duos is 390~500 and the max is 685mb so so, than when press clean RAM, it closes a certain number of processes but only 50mb ram max it decreases... Why?? And what can i do about that??
Thanks!!!!

First, the Linux system (as Android is based upon) always try to make use of all available RAM. Having unallocated RAM is wasteful, so all RAM not used for apps, is allocated for caches etc, making your device not slower, but faster. When this memory is needed for better purposes such as apps, it is dynamically reassigned.
The other question I'm quite don't get, please clarify it and I'll give it a try. But Android do start and stop apps as it see fit, unnoticed by the user. This is the Android way of resource management, instead of paging/swapping. I.e. Android "swaps" entire apps, not RAM. As a developer, you have to know this, making your app able to handle a restart as transparent to the user as possible.

Yes, i know about that but i'm crazy because when my phone is slower i see the ram and it has apparently 500mb used from 680mb total... And i click on Clean, it closes like 20 apps and clean 100~mb aprox. of ram, and the phone becomes faster... That is my question, i know about linux... in galaxy s duos have an option to kill until number of processes you would... But didnt work i think because, i put max to 3 processes but even when i close the apps with back button, like facebook, instagram and another without home button, it stills on memory, taking the phone slower
But thanks for trying help me :victory:

I have it but dont know how to use? I need to select one by one the apps that i want?? :/
It's need root and you need to select the desired app, when your screen turned off for some minutes then greenify force stop your selected app.
If you don't understand try to search in YouTube and xda
