When my phone just started it is about 180, then it dropped to 90 after extensive use (20ish minutes).
That is even after using advanced task killer...
Anyone else experiencing this?
That's still plenty o' memory.
Keep in mind that there's a lot of folks getting good performance out of Droids, Milestones, etc, that have half the RAM (256) to start with, and hover around 20-30mb free in normal operation.
I was curious about this myself and was going to make a thread about it soon. Regardless of if it's enough free memory, I'm still a little confused as to where all my memory is going. When I close everything with TasKiller, I can get to about 175 MB of RAM free. I have a friend with an EVO that always gets well over 200 MB free, and I imagine that the HTC Sense UI would use a lot more memory than Launcher Pro (which is what I'm using)... but I could be wrong.
I can hit about 230 free after killing all tasks. I uninstalled all the ATT apps not sure if that had anything to do with it. I also use Touchwiz with only 2 Widgets accross 2 home screens.
maybe its android 2.1 that has a cap on the memory
Guys, a little piece of advice if you're new to Android. Don't sweat memory usage, if it's above 40mb free you're generally doing just fine.
And those apps that are using memory aren't using much if any CPU cycles or power, most are just cached in case you need them, and are wiped out of the cache if something else needs the memory.
On the other hand, if you're killing a lot of background tasks by reflex, those tasks are taking MORE time and power to reload again if they're no longer cached, plus there's the overhead of the Task Killer. It's especially bad if you have a Task Killer set to auto-kill apps, even more overhead as the task killer has to remain active to sniff for things to auto-kill.
Task Killers are the devil, and they're like crack. Just walk away.

Thats what some people are saying. They said we should see more avail RAM when the 2.2 update comes out. Or if someone can do some kernel wizardry.
The specs on the box do not mention any amount of RAM. I would be unhappy if ATT only put in 256! I didn't look through the manual maybe it says in there.

Indeed that seems to be the case, many threads about the issue can be found elsewhere on xda or google. Also this technical article from google: developer.android.com/sdk/android-2.2-highlights.htm (I can't post links yet)
yep ur right says more mem support at near bottom http://developer.android.com/sdk/android-2.2-highlights.html
2.6.32 kernel upgrade
HIGHMEM support for RAM >256MB
so it seems cause of the kernel
Well that's interesting. So you're saying that no matter what, right now we're only accessing 256 MB of RAM? I hadn't heard that before about 2.1, but that would be cool if our RAM essentially doubled in 2.2 (along with the massive CPU speed gains seen).
Again, it's not so much being worried that I'm going to run out of memory. It's simply a discussion on what people think we should be seeing. I'm certain that I don't have enough running to use 300 MB of RAM, which is why the question was raised. So I think we have our answer now and can rest easy waiting for 2.2.
As for the task killers... I honestly am more worried about CPU cycles for things I've left in the background than RAM. I've noticed my phone basically hang for a few seconds every so often, and I can only assume that something in the background is causing it. I'm going to turn off auto kill and not kill tasks manually for a while and see if there is any difference during use.

40? No. 40mb of free RAM is unacceptable with todays smartphones on the market. I own a Captivate as well as a Nexus One and my Nexus consistently has 200-250 avail RAM. However when they first released the phone they only released it with 256 avail making my phone normally read about 120- 130 avail RAM. Now its been opened up to the 512(unless it had already been rooted) and it is much quicker than before. I'm wondering if something similar has been done with this phone.
well if it does have more than 256 mb it will be able to recognize rest in 2.2 as you said about ur nexus one maybe its just that the software on the captivate thats showing less you never know just gotta wait till some dev figures it out hopefully not to long
My phone is reporting 325mb of RAM, so I'm not sure if this is the same kernel limitation. I would appreciate if anyone could enlighten me as to whether or not the full 512 I was under the impression this phone possessed will be available under 2.2.

That's exactly the limitation being talked about. Yes, 512 will be available after 2.2.
Until then, don't worry about it. Don't install a task killer, they just waste your time worrying about it. The OS has built in levels of memory where it starts to kill off different types of apps from background idle, all the way up to foreground active if entirely necessary. It WILL kill the extra apps if you need the memory.
I have been running ATK constantly since I got my Captivate a couple days ago. Not really concerned with memory usage as much as battery life. So far I get one full day of use before recharge, but I expect that to go up once I stop turning on the screen every few minutes to play with it. Can auto task killing negatively affect battery life?

Task MAnagers!?!?!
I'm not sure if i am 100% right about this maybe won of the senior members who does know can enlighten us on this...
But I remember reading somewhere that task managers some times can hurt your phones RAM usage. I don't use one anymore unless it comes stock. and then I rarely find a reason to open it on mine. In standby I am running around 80-100 with 200-300 of freem RAM so with the SGS4G i don't think i will find a reason to use more than the stock utilities. I somtimes will installl a tool to monitor the RAM to see what I'm usin but every once in a while I go through and uninstall anything I don't need right away. I figure ussually being in good internet coverage I can always put something back.
So does anyone else know about wether or not the "Task Manager" could actually be a tantric in some cases?

So widgets are the ram hog on this phone? I have been constantly clearing ram in the task manager to help with speed. I only run clock, battery, and calender widgets on my device. Are they enough to boost me all the way to 240+ even after a RAM clearing? Considering the age of this thread is this still the case with new ROM's that are starting to roll out? I'm still stock, and very noob to android devices, but the urge for mods is growing given the positive responses to them.

You shouldn't have to worry too much about RAM usage. A lot of it used by the OS. But yeah widgets does lower it and whatever app you're using. But I hope you don't resort to using task killers just to save 50mb's of RAM. It's there for use and shouldn't be looked at too much.
Mine shows about 400/626, but haven't noticed any big difference in battery drain when it's at 300/626.
Simple answer....everything hogs ram. The best way to tell what's worse is settings » applications » manage applications and watch your ram usage when you have certain things running. You will notice what is hogging more than others.

Thank you for the info everybody. Been ruinning just fine all day with the ram almost maxed out, hard to break that task manager habit though lol. Goona keep reading before I root-flash-mod need to make sure I get it right the first time.
On the moon our weekends are so advanced they encompass the entire week
Samsung and Tmo set many bloatware to run ALL the time and hogs RAM
via Linda file manager and auto memory manager (which tweak's android's memory management, not a standard task killer), i saw many apps that always run (many with priority equals to android system and the phone app) such as "wifi calling, visual voice mail, my account, qik, device management, drm, etc.
not everyone use these apps and they take up precious RAM and tiny amount of CPU cycles.
worse, however, is how the phone keeps loading unused, unaccessed, unwanted apps into memory (been weeks since I used pandora, yet it keeps getting reloaded into memory).
from clean boot, I get 150mb free. after a week, I get 45-55mb. This causes memory manager to kill off app as soon as you switch away and alot of stutter (dont you hate it when your browser gets killed)
Dont know if theres a fix for this. I tried tweaking the OOM parameters but it doesnt seem to work on this phone. Samsung probably tweaked something that broke this.
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.
Read the article linked to in the first post of this thread here:

Pay special attention to the Addendum at the end where it talks specifically about the way Android/Linux handles memory.
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.

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

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'm curious about how much free ram everyone has on average after their rom has finished booting and stabilized! Post it here!!!

i run about 40-80mb free on average just the way i want it.
Android uses ram differently than other operating systems like windows or linux,
it fills your ram with things that you have run already in hopes that youll run them again and it will be alot faster the second time. if it needs that ram for something else, it just kills a program and removes it from ram (this takes VERY little time)
so the more ram used the better

thats about all it holds. the VM heap settings are what causes this (in part) each app gets its own virtual machine to run in, this has a limited heap (ram) size of whatever is set in there.
so if your VM heap size is set to 48mb... 48 * 5 = 240mb and 48 * 8 = 384mb
add in whats needed for Android system, kernel, and various background processes that you need... its all gone

it all depends on what your min-free settings are.
the apps that fall into each category are slightly different for each ROM, but whatever the highest setting is at is what your free memory should sit around, and it can and will fluctuate alot for seemingly no reason.
and before you all go out and change them as high as you can, just know that free memory is wasted memory, it takes NO power to keep things in memory, but it does take power to put things in memory every time you open it!
This explains it a bit better than i can.

Hey Guys,
I am relatively new to the world of Android being an IOS man until I took the plunge and got this cracking little Nexus.
One thing I have come across is how I seem to be losing RAM over about a period of an hour or so. On a restart my RAM reads about 1.3gb free. After some time it goes to 900mb free. I have APPs like Advanced Task Manager freeing up RAM every hour but thought that someone may have come up with a software tweak or solution that may stem the flow.
I am running a rooted with standard ROM and ElementalX Kernel.

A memory leak is when a single app (or multiple apps) leak into memory. This would mean if you look in RAM, app1 is using 10MB. Then an hour later app1 is using 40MB, then an hour later, app1 is using 100MB. Its only a leak if the particular app is grabbing more memory and never releasing it.
What is described here is just RAM being used, which as already covered by everyone else, is a good thing

As posted, let Android manage the RAM. It has become quite the mature operating system over the past few years. It will know when to remove an app from RAM when it needs to free some up.
As a general point of why you basically want less free RAM: RAM uses the same amount of power whether you have 2gb free or 1 byte free. The entire stick is powered on. When you cold-boot an app, it spins up the CPU to do what it needs to do to load it into memory (compile it in the case of a JIT compiler, etc). After you do what you want to do in that app, it's fine to keep in RAM. Again, that RAM is going to either be useful, or sit there empty, doing nothing. The advantage happens when/if you want to access that app in the future. If you offloaded it, the CPU has to spin up again (which uses power) and load it into memory. If it's still in memory, it just looks at the pointers in memory and addresses it. And this is where Android has matured and knows how to handle itself: when you leave all your apps open, open another one, and reach your RAM limit, Android knows which app to offload. I don't know the exact formula, but I'm betting time last accessed is a huge (heck, it could be the only; I simply don't know) factor.
And as @rootSU mentioned, this is all assuming normal behavior. If you do actually have a memory leak, that is bad, but you are describing normal RAM usage.
