[Q] Why no ones talk about the lag cause by Insufficient memory

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

Cool, does that remain for few days? How often do you restart your phone?

free memory is bad memory!
why don't let android do it's job?! this ist linux with a clever memory management, not windows 95!!! deinstall all auto task killer android is handling the memory very well. it uses all it can get and if it's not enough it kills old uses apps from it. why have free memory, there is absolutely no reson for that! ram is fast, let the often used apps be there not on slow sd or nand!

QFT!
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.

Technically, it's hard to tell the difference performance-wise. Android does it's own memory management, but also it won't hurt anyone if you try RAM tweaks and see the result for yourself.

Well, thats true, but the RAM is meant to be cached (fully used) for quickly launching the desired application.

Best way to optimize RAM for starters is to monitor your background, cached and running processes well. First, freeze stock background running bloatware using TB. Mainly DRM content (some say it messes with ringtones and stuff but I never experienced that), wsynclmps, syncmIDs, maps (unfreeze it only when needede), software update(this really doesnt help and is waste of RAM+space), pico TTS , TTS service(these two are for voice to text conversion and are literally not much used), samsung account(is waste compared to play store), two email ones (use gmail app these dont help much), social hub , samsung push service.Choose adrenaline engine if you want multi tasking and v6 if you want more free ram.You can mix both of them but its risky and needs some scripting skills to remove the conflicts they make and highly NOT recommended.

completely agree with this one. less ram is not alway a good news in android system since it has unique RAM management. for quick acces and less RAM r/w some of app is stored in RAM's cache. SGY's default ram setting is already good enough for multitasking and gaming option. if you want a better performance in your device you don't need lesser RAM. instead of it you need a better memory and app management.

High RAM usage?

I've noticed on my e975 EU version even with 0-1 apps open the ram free is only 1gb... Other phones have far more ram available including my previous nexus 4. Anyone else notice this? I often find with quite a few apps open I only have 2-300mb free

I've never seen less than 500mb free but its true. Never more than 1gb.

I checked earlier with 0 apps running it was at almost 1gb used.. what on earth is using almost 1gb!? If phones with only 1gb can use less than that on jelly bean.. why does this phone use so much?

According to ram usage i am using approx 400mb, task manager says im using 800mb. Maybe 400mb is reserved for system? This is on stock rom with only a few apps installed.
Keep in mind free ram is wasted ram. Free ram is like having a fast car and only using first gear. Still curious to know where it all ram is used nontheless.
Sent from my LG-E975K using xda premium

I get what your saying with 'Free ram is wasted ram' but when you run out of ram.... things will start to stutter.
Having a few apps open to find you only have like 300mb left is insane.
I've had phones with only 1gb ram before and with lots of apps open they are using like 700mb/1000mb... it's almost like this phone is going 'Oh I have 2gb available so i'm just going to chomp up 1gb for the sake of it and leave you with 1gb left....'

If you're root use an app called "Greenify". Simply hibernate the apps that don't use adding to the list of the app, then add the widget to hibernate the app that you added (all except whatsapp, twitter in my case). In addition I use a tasker manager (don't added to greenify) and add a widget too, that combination gave me 1,2 gb free using a lot of widgets

Im stock un-rooted.
I only have 2 widgets on my home screens, 1 is the standard world clock and the other is play music. Tried removing both and it barely made a dent...

That's weird, only 900 mb free?? Mmmm, try using advanced task manager from the play store (I don't remember if root is needed), that will free you more memory. But in the 900 doesn't mean that the phone will be heavier, backward the used ram is exploited to make the Optimus lighter

Seems odd eh...

I also have 600 - 700 MB of RAM when I do not use anything.
There are just icons on my homepage, and a calendar widget (stock one).
At this case, It gives me 600-700 MB of free RAM. I always use "clear RAM" button. But why it gives us so limited free ram?
I used to use 4X HD with 1GB of RAM. There were 350-400 MB free which almost same with this optimus g?
Can someone explain this situation?
Or I think we need a new update. or CM10.1

It just feels like the phone is using up too much or isn't optimised properly.
As said above, phones with only 1gb available use about 3-500mb... Our phone with 2gb available seems to use about 900mb-1gb with nothing running. It's like it's gone 'Oh there's twice as much free so I'll just use twice as much...'

What about the AOSP custom Roms ...is the ram usage is same on that kind of Roms too?

No clue, i'm 100% stock unrooted Maybe someone will know.
My nexus 4 was far better at ram usage than my optimus g mind you. No matter what it never used more than 1.2gb

I think the Lg UI(stock firmware) is a memory hungry ...i suggest to try AOSP roms with lg skin :thumbup:
Sent from my LG-P500 using xda app-developers app

Using cm10.1 and have always about 1.4gb free, and this is more than enough for everything.

Y, stock rom have a crazy high ram usage, now im on PA and got 1.2gb free.

My doubt would be if, on stock rom, you get many slowdowns when you experience this high RAM usage. For me (who doesn't still have a LGOG, but is seriously thinking of buying one), it's the thing that matters most - if the lack of free RAM results in worse usage.
Otherwise, most efforts could do more harm than good - a task killer that kills an app which will restart seconds later is wasting RAM and battery instead of saving them.
I'd give priority to greenifying unruly apps you need often and freezing apps you rarely/never need but won't/can't uninstall (with Titanium Backup, or any other app that can freeze system apps) - always making sure you're not freezing some system app that will bring your phone to its knees. With this well configured, I'd say a task killer would only bennefit those of you that rarely use your phone. Everyone who often takes it out of their pocket and updates Facebook/Twitter or plays games should let Android take care of itself, as it will keep in memory the apps you've been using the most - as it should.

Don't use task killer apps, they aren't good for Android. Maybe something like a LMK Manager but you need root to change lmk.

M$ Windows does the same thing - if you have 2GB it uses only the half, if you have 8GB is use nearly 3,5-4GB. I think it preloads a few things including the most common used apps in memory perhaps?

Whats using all of our ram?

I have been trying to figure out why the Note has so little of the 3 gb of ram available at any given time. After a fresh boot, I might have 1.3 - 1.5 available, but that quickly disappears.
I have frozen all unnecessary apps with Titanium Backup, yet after launching just a few apps, I'll be down to 300 mb or so. Looking at the active applications list in task manager, the apps listed are nowhere near to adding up to over a gb of ram.
Tablet seems to be performing fine, I'd just like to know where the ram is going and why. Especially when tablets with 2 gb of ram seem to have much more free at any given time.

what the heck?
i constantly have to go back and clear apps, this is such a let down because my htc one could load much more than this, and every1 knows, htc one is no where near the spec of note 2014..

I'm not rooted but I noticed the same thing with the ram, I thought rooting and freezing some Samsung apps, specially Knox stuff, would free up a lot of ram. I'm starting to think that it's not a big deal and Android frees up ram as needed before it starts to get laggy (of course it's not perfect). I think lag issues are somewhere else and not so much in freeing up more ram. Don't you feel anyway that your note is a lot faster after rooting and freezing those apps? As far as I know most rooted users feel that way...(?)

I have rooted mine about two weeks ago then froze all sort of junk listed in here and some other I identified mysefl. Now my used ram remains around 500 clean and around 700-800 when I open few apps. So guys the secret is getting a lot of useless apps frozen especially knox stuff.

Yup, stuff is kept in the RAM as much as possible to increase performance. As soon as an app requires more RAM than is available, the system moves apps from the RAM as required. Clearing the RAM only increases the time it takes to start an app next time.

People are used to Windows needing free ram and do realize that Linux is a completely different animal altogether.
Here is the article for those that want to understand the ram usage.

Okay, guys. Disclaimer: I'm an IT professional and the Mobility expert for my company. I know how the RAM is used and why. I'm just curious as to what is using it. Especially in comparison to the Nexus 10, which has 2/3 of the RAM and has approximately the same amount available at any given time.
I wasn't looking for assurance that this is how it's supposed to work. I'm curious as to what you guys think is actually filling it up. Since I have disabled most unnecessary processes and only run a few apps at any given time, I can't see why so little is free.

The objective of good android RAM management is to keep RAM full of the the highest priority apps. This enables faster and smoother response. The apps that are in RAM on your device will be different than on someone else's device. If you are curious about how android decides what put in RAM and what to take out, do a google search on "android process lifecycle"

if you're concerned about ram usage go to dev settings and change the "Limit background processes" to something more you liking.

Low memory!

How much FREE memory do you guys have when in normal usage (with browser, Facebook, whatsapp, tapatalk open..)??
Here I usually get 200 free, so I constantly have to free memory (it goes from 200 to 450, but few minutes later, it will be the same thing).
Help, anyone??

I usually have 1.1 gb free with kakao, whatsapp and basic apps running in the background. I close Facebook as I leave it, Facebook is a big memory hog.

Look at what is running. It sound like something is running in the background that is sucking up the memory. If you do a reset and re-install of everything, before you find out what is causing the memory problem you may be right back to square one.

I agree with this, when your talking free "ram" as shown in the task manager , it is what is running at the time, not what is installed?
In my system i have not seen the "ram" ammount drop below about 350m ever.

Usually ranging between 200-400 free. Usually if I close the browser and clear my task manager, I can get higher. The thing is, why would you want all that unused? If your battery isn't being drained and your phone isn't lagging, you should be good to go.

to check whats eating up your RAM, go to settings>>general tab>>apps>>running tab!
you can also go to battery settings to check the most power hungry apps!
or you can install DU Battery Saver!

PsykoGeek ram or memory is what I was talking about but that also includes the apps or software that is installed on the phone also If the underline problem is not found first, anyone can do a factory reset and re-install the app and there is a very high percentage that it will come back.
I would look at the app that I have downloaded and start to turn them off one by one and see which one could be the culprit. After you found one or two, see if you can live with out them.

High RAM usage is actually a good thing on Android unless you use a lot of emulators like I do. On PC, low RAM is good, but on here the more RAM that's used the better it is. Makes opening apps much faster. What would be killing the battery is an app keeping your device awake even when the screen is off.
