I'm usually sitting on somewhere between 60-100MB of free RAM. Now keep in mind, I have LOTS of widgets running, a gorgeous theme, spb 3d launcher, etc...and I prefer to keep those things going, because that's how I get my value from my phone. I don't think the phone is slow by any means...but because I'm used to using Windows, I'm paranoid about low ram. Should I be worried, or is it fine as long as I'm not experiencing bad performance?
Moving some apps to my internal sd card wouldn't do anything about RAM, correct?

I'm not an expert at all, but rather someone with the same question. As explained to me, the newer versions of android are most excellent in memory management. The need to manage memory, like in windows, is not there in newer versions.
With that said, being from windows, seeing low memory counts freak me out. I've been convinced by the people on this forum, to give it a try and not freak out. Avoid using task killers and such. Only thing I do is remove apps and Widgets I do not use. I've not regretted that advice.
It really all depends on what you are doing on the phone. If you only have 10 MB left, but are only checking emails, you are fine. But if you were to start playing a game from the terga zone, then you will have problems.

Right, but, my understanding is, android will shutdown unused tasks to accommodate the need.
I learned with windows phone 7, there is a balance between live tiles, battery life, and performance. I assume that android has a similar premise. Do I need 40 Widgets on my desktop. What is the trade off if I do.
Again, I'm # noob to android...but this is how I'm proceeding.
Android keeps things in ram, which I would think is so apps can start up faster. If you are using something and it needs more ram than is free, android will remove something that isn't running to free memory. as far as too little, ram not being used is wasted. So just because you have a low amount free means nothing. The only thing that would be bad is if running services and apps needed more ram than the phone physically has. so just because there is little free means nothing really.

Hello,
First few days with Nexus S 4G and love it. I have noticed random lockups or delays in navigating the home screen or applications. I use SPB Shell 3D on my Tab10.1 and used it on my Evo 4G prior to the Nexus. Never really had this querliness and just love the app.
I use Active Apps (pay version) and see my ram gets in the high 200's to the 300+ RAM available. I can clear level 1 and 2 back/foreground processes and that seems the clear up the lag. But thw lowest it goes is low 200's. It is somewhat alarming considering I am not throwing anything at the Nexus that I didn't with the Evo 4G. I figure the newer 1ghz would perform pretty similar.
Was I wrong to assume? Is there something I should be looking out for? Is this a known issue with the phone or current Android version? Is there a work around or fix?
Thanks in advance. I know I could uninstall SPB and ensure that isn't taking up a ton of RAM or isn't the cause of the lag. But thought I'd ask before I undo the hours I took customizing my setup.

why don't you just do a titanium backup of the application settings and then remove it? i'm 99% sure that is the cause of the problem...
Ill look into it. I use Mybackup Pro but don't think it takes on app data. I thought Titianium requires root but ill check. so far its not hindered performance but ive tried to watch RAM levels and services via Active Applicationa program.

Im really sorry for asking but, Ive exhausted all other search methods to find an answer. What can I do about the extremely low ram availability? Ive got like, on a good day 110 out of 329mb available. Is this normal? Ive tried reading up on flashing a new kernel but Im not positive this will fix the issue.
Im running the uvkg4 2.3.4 with the kernel that came with it. Go launcher sits on top of that using about 18mb. Maybe Im just expecting to much from my phone?
Any help is greatly appreciated. Even if its to yell at me cause I missed something while searching on here.

Dude i think its a usual problem i have a galaxy fit and i also have aost 100mb-130mb of free RAM out of 280.
So, May be we are expecting too much from our galaxies!!
However in a HTC phone( i dont remember the model) it has 784MB RAM!!!...
the best way to free Ram is close useless running apps and uninstalling them!

My wife has an LG Optimus for Tmo...and she's getting like, 261 of 418. The difference seems only slight but, I'd like all the ram I can possibly have. I use the built in task manager to keep up with running services. TB for freezing or uninstalling. I don't have a whole heck of a lot of things left to kill that would equal 100mb. Maybe 60 at most.
I don't know. I am still interested in the whole kernel thing though. I've read what a kernel is, and is supposed to do. I just don't understand what exactly the benefit is of flashing one over. Like drhonks, I've read all about it everywhere...for the life of me can't find what the exact benefits are. Same thing with the modem. I'd like to flash that too to fix the constant drop of data connection even though it reads 4g, but I don't know that that will fix that (lots of thats) problem either.
Does it matter? 100mb of free ram is the same as 200mb free isn't it? It's all unused. with GB, it has a pretty good system for managing tasks, so I didn't think it would be a problem.
Sent from my SGH-T959V using xda premium
Well, that's true. Even while trying to hurt my phone it doesn't bog down or lag out due to low ram. Thank you for the insight.
Also, with the modem thing..should I open up another question for this? Its something that's now becoming quite the hassle, it drops data way to frequently to be normal.
I read somewhere once that having lower ram is actually a bad thing. The android operating system stores information on apps to help it launch those apps faster. When you clear it out it takes longer to launch because it does not have the information stored anymore.

For the most part I only have the necessary things required to make my phone work turned on. Aside from Go launcher, and a couple widgets (1-4mb a piece) running. I'm just stumped on where the rest of the memory is, or what's using it.
Are you getting a bunch of launcher reloads? If so, then you might wanna consider switching roms. I tried a few rom/launcher combinations and stuck with audiophile ftw with the newest init.d pack. Stopped my launcher reloads unless I was using a really ram intensive app like plants vs. zombies.
The ram operates like on any computer. if it is cleared, you need to rebuild your workspace cache. If you clear the ram on a phone, you will have to wait a bit longer for the cache to rebuild. It's minimal though. unless you get an error or an fc, I would say there is no need to clear your ram on the phone, especially with the great built in task manager. For games zombies or pewpew, yea, it makes sense to clear it prior to playing, but the system should do it for you anyway, shouldn't it?
Also, do what fbis suggested. Will make a difference

Yeah honestly you think about what takes the most ram in use stuff like browsers,skype,youtube etcc...but of course you Wont be using all of them at the same time!

After using my phone for a while, I usually have 60-80mb free. Just different services running etc... Phone doesn't slow down, never have any real memory problems, and the only time I sometimes get a launcher reload is after playing a memory hungry game like PvZ or Gun Bros, and even then it's pretty rare.
Unless it's malfunctioning, those apps sitting in memory will just close if something needs it, you can see this first hand if you view your free memory right after playing a game, I usually see anywhere between 140-200mb free. It then gradually goes down as I use other apps and as some of them auto sync etc.
Except in the case of a buggy app, Android seems to be pretty good at managing memory.
I believe some of the low memory paranoia would go away if we had a task manager like Windows has where it tells you what memory is Cached, Available, and Free. I'd be freaking out as my netbook only has 3 mb free out of 2 gigs right now if Windows didn't tell me the other info lol.
Yea, I'm not getting any heavy launcher reloads. Even if I'm playing a Gameloft game everything seems to run quite smooth. I guess I was just freaking out about the numbers.
I thank you all for the responses and help. I think I'll do a little more research on flashing modems and such before I ask anything about that. There's a helluva lot of information to read about.
As what everybody said here, the 100ish MB free RAM is fine. Android caches the processes so it'll load up faster when you open an app again. Of course, if you clear your RAM, you clear these caches too. When Android needs more memory, it'll kill an app to provide for more memory.
Also, do NOT use a task killer. I can't emphasize that enough. Using that will kill your necessary apps, which will eventually cause your phone to do random reboots. Many people have reported that.
I have done the manual ICS update 4.04 that was recently released in the general section of the forum, and I noticed that the memory is much lower compared to 2.3.6. The memory averages around 50MB, sometimes 100MB, and showing used memory around 285MB. I was wondering if this is normal as some of my games force closes after i start to play. the games uses quite of bit of my phone's resources and was working perfectly on 2.3.6. Also, i use the GO Launcher EX and i tried not using the launcher, but it only frees up little bit of memory. My phone is not rooted, everything is stock of course. I was wondering if anyone else has the same or similar problems? or is this normal in terms of the ICS OS using more memory?
anyone knows????
Give me a list of what services are running and how much ram they're using. This is done through settings > apps > running.
The same is the case with my phone. Sadly thats a compromise for ICS, you have to install custom rom to free up more memory.
I had the same problem at first .
you have to install a ROM+KERNEL that support BIGMEM.
I use Pixel Rom 1.72+ Airkernel 3.9.5, I now have 180mb+ with many programs running. its super fast/stable

i was actually looking into that ROM and kernel. How is it in terms of performance and battery life. I'm looking for a ROM and Kernel that increases both lol.
Also right now it says 292MB used and 46MB free. the processes running are settings (34MB), go weather (4.9MB) go launcher ex(34MB), go sms pro(7.5MB), go switch widget (4.1MB), google services (8.5MB), android keyboard (11MB)
Also for extra info, here is cached processes:
go weather (4.8MB) launcher (14MB), media (5.1MB), my uploads(3.4MB), package access helper (3.5MB)
in total, including cached processes, 134.8 MB used
You're sure that is everything that is being shown in the two pages? If so, it looks like something in the background likes eating RAM and doesn't want to share.
Regardless, could you download terminal emulator or something similar (or just use adb shell) and type: "ps > /sdcard/ps.txt" and upload/copypaste the file/contents. It's not a particularly great way of figuring out memory usage but i can probably make do and see if something is wasting it. I know on a fresh boot i have much more lying around in the cache than that, without opening any apps - mostly google sutff.
E.g., 24MB launcher, 11mb core apps, 15mb maps (and more in running), 36mb play store and so on. Although currently on ~402mb bigmem, i don't remember it being much less before - still 200mb used (as always) and cache is generally filled to the brim.

Hi. I have the same memory problem, i created the ps.txt. I don't know how to read this txt..
What does mean these things :
USER PID PPID VSIZE RSS WCHAN PC NAME
What are ppid, vsize, rss wchan??
Envoyé depuis mon Nexus S avec Tapatalk
PID -> Process IDentifier -> Wiki for more info
Vsize -> Virtual Size -> RAM usage (SWAP + Physical)
RSS -> Residential Set Size -> RAM usage (Physical only)
wchan -> Some waiting indicator, never looked into it
I just want a detailed list of what processes are using up the RAM. Basically i'm looking for something with excessively high RSS and just comparing it with my phones results.

Too sleepy (and mentally deprived) at the moment to give a good answer. I would, however, try ditching go launcher altogether (preferably uninstall, hopefully not too much trouble) for a little while and see if it gets better. I can't tell for sure without better memory analyzers but it is possible golauncher has gone haywire (or maybe not, trial and error ).
If not this, i notice there are many kcryptd processes going on. To my knowledge that is kernel based but i know not what it does or what it's for, did you encrypt the phone by any chance? I havn't run stock in too long to remember how the ps list was. I should be able to give a better, more thorough answer tomorrow regardless though.
edit: also, i've attached my own ps log for reference. We're talking around 205mb used and 197mb free when that log was taken. Have a look. Note that RSS (all in kB) can be shared, so that 20mb from each go launcher process may well be the same ~20mb between all of them which they all have access to, so it's not 100mb+ used, just ~20mb.
I'm pretty sure I haven't encrypted anything, is there a way to find out what has been encrypted? I have removed go launcher ex and the themes. Will now see how the memory is, in the meantime, go sleep Harbb lol.

Wow I'll have to try that pixelrom and airkernel for sure (especially since I just recently rooted for the first time a couple days ago).
The miniscule account of RAM we have on our phones to play with is literally my only complaint about my Nexus S. If I could seriously UP the free/available RAM like ismailham says, I'd be falling in love with my phone all over again!

Definitely non issue. Done it to send mine for repair for a failing BGA, it was near painless. The biggest "trouble" was removing CWM and SU to make it look stock.

Recently my Note started getting very slow and sometimes lags... I clean memory and it sometimes helps for a while but most of the time it doesn't change much (although normally it uses max. 900MB anyway, so more than 1GB is free). I used trim in the past and it helped, but now it doesn't change a thing. I have 3GB free space, nothing really runs in background that could affect performance. The most lagging app seems to be Chrome (so I sometimes think maybe its newest version is the culprit), but others also lag sometimes (including the launcher).
I have a clean rom installed - normal Samsung latest update with root included, nothing fancy.
Could this be some hardware failure (flash problem maybe)? Or is it only software and I should clean the system or something? I have many things installed, but not many running. I tried using Greenify but it didn't change much.
I have had that a couple of times and normally find it is a badly behaving app. A full wipe and then just putting back the apps you really need one by one has always fixed it for me.
If you have a custom recovery, format your cache partition. Mine got horribly slow, I formatted cache and now it is very speedy again.

How is this done ?
Thanks. I will try to clear cache and find out which app might be causing problems.
try using LagFix to trim the garbage on the ssd.
I used trim before - didn't help.
By default my Note uses pegasusq governor with speeds from 25MHz to 1.7Ghz (so I suppose I have non-stardard kernel, I don't remember what I installed though). :laugh:
When I switch to interactive governor it works MUCH better, but I also rise the minimum 25MHz to something higher (currently I have 225MHz as minimum) - it looks as if it sometimes can't wake completely from a very low CPU setting and gets stuck on low setting (lagging like hell)...
Or maybe my kernel is buggy - I should clean the whole tablet and start over with new ROM and a standard kernel or something... I just have too many things there to even attempt that right now and too little time.
Thanks for your help, anyway.
Cache files by apps
We have had two issues with one of our note tablets.. The 32 gb one seems to not have this issue.But Bonnie my spouse uses hers more then i do for social media stuff . Hers is a white original 16 gb. I know there is slight hardware differences.
1 . tablet getting super slow.
2. Storage space wrong and being taken up for no reason.
I found on a website that helped do not remember the site
Down load a app from play store called Disk usage.
Look thou the apps in the chart. You will likely find 1 or more apps using a huge amount of cache files. For our tablet its always good Plus that is the worse .
the file was almost 5 gb.
Once you find the app that is causing such a huge cache file Go into settings/ apps
then find that app and delete its Cache.
It should speed up the device and restore lost storage space.
This is a KNOWN issue . i see many ask about in the past. I just found this solution.Sorry if its already be discussed or found
Thanks. I think this is the same problem - I got rid of the lags by freeing 3GB of space on the internal SD Card. Now it's just like new - no lags whatsoever.
Next time I will buy a tablet with at least 32GB so it will be harder to fill up.

Or you could use FolderMount to move the Android folder to external sd. That tends to free up a lot of space.
