The Galaxy Nexus is supposed to have 1GB RAM
When I go into Apps and running Apps my phone says I have 326MB RAM used and 306MB free
I havent noticed the phone been slow at all but is this normal or am I missing RAM?
Also is there any way of stopping apps like WhatsApp, Facebook and Maps etc to be always running in background?
I also have like 350Mb used and 280Mb free. In total, is like 630Mb. But I think that are things running in background of the O.S you can't see.
But in any time I feel like my phone is going slow. In fact, it's the other way, I'm very satisfied with the speed and multitasking.
The apps like google maps or whatsapp will be always in background. Also, mention that opening the settings it consumes like 43Mb of ram. That is pretty huge.

Android keeps whatever it can in memory for quicker access; it's not like Windows where it's better to keep the memory free. You're fine. The missing 392 MB is reserved for the GPU.

Uninstall them. Unless they're consuming CPU time, there's no harm to having them running in the background.
I was thinking it might have been reserved for OS
Im am not bothered by it been missing or the other apps running as the performance is great but was just curious
I just have to figure out which app is causing my screen going to sleep totally or not been responsive when trying to unlock via pattern unlock. It may be Juice defender as I rest the phone and reinstalled apps gradually. It was one of the ones I reinstalled again in last few days and its happened again
I installed a single widget from Beautiful Widget yesterday and today I've had the launcher redraw itself multiple times and this is aomethig I've never seen before. How much free RAM should be available? I'm hovering around 120. Stock Nex HSPA running 4.0.1 on T-Mobile.

I usually hover around 350mb free... 120 is seeming a little low. Are you exiting apps with the home button or the back button?

Either or, no preference either way.

Often i stay around 120mb free ram so i think you are functioning normally.
Free ram is unused ram.
You only need as much free ram as the next, uncached task will require. On Android this is unlikely to ever be more than 80MB.
On this basis, if you have 120 free you should be fine.

Uh no. Free RAM consists of cached but not currently running apps and cached kernel resources. It is by no means "unused".
You also need a lot more free RAM than what the next app you are going to run requires, due to kernel caches and paging policy problems. If you are actually interested in learning how memory management works I suggest you read up on virtual memory first before giving others advice.

Don't be snide, it's unbecoming.
"Free" in the context that the OP used it is exactly that, free and unused - as in not used by anything at all, empty. Perhaps you might want to look that one up.
I responded to him in context and accurately. From an end user perspective it's a more helpful answer than a technical one about paging, caches and kernels...
I suggest downloading Cache Cleaner NG (yes, the "NG" one) from the Market if you're having lag or other problems. This will help no matter which definition of "free RAM" you choose to adopt I can say, though, that in my experience a lot of lag and force close issues have had more to do with cache and app data than with "free RAM." For example, on my Fascinate I'd have 120 MB or so of "free RAM" according to my system settings, but I'd still have major lag and more force closes than a chain of Circuit City stores until I cleared app cache using Cache Cleaner NG. This is different from wiping the cache partition in recovery.

Free in the context? There is no context needed here, as there is no ambiguity. Free here refers to exactly one thing: the amount of free memory reported by the Android system. The Android system uses a Linux kernel and reports free memory the way all Linux systems report free memory: all kernel and userland caches are reported as free memory. Free memory is not unused memory. Free memory is physical memory pages that are not currently marked in use by any virtual page entries. Free memory is used as cache by the virtual memory system. If you understand the virtual memory system at all you'd realize that truly "free and unused" memory doesn't even make sense in a virtual memory system. Truly unused memory is just cold cache, once the cache has been warmed up, the idea of unused memory becomes irrelevant.
Basically OP, you should never have to worry about it. This phone has more than enough RAM to handle anything you throw at it. If it ever feels "sluggish" just give it a reboot. No need chasing your tail to free up 15MB of RAM that won't make a difference anyways.
Thank you. This is what I figured as I've had quite a bit of experience with Android dating back to the G1 (it's why I don't have a task killer installed). Yeah, the lag is annoying although it's way better than my Xoom's. I was just wondering what you guys were hovering at.
I do have an app that turns itself on in my running apps list (it's ESPN's Fantasy Football app) I want to keep the app but it's sort of annoying seeing it pop up there all the time. Is there a way I can force it to stay off?

Do you have a widget running for this app? Any app that has a widget on the main screen will automatically run because of said widget.
I personally think thats REALLY low. I'm typically sitting over 400MB free with a couple widgets running and battery monitor in the background as well.
As of this moment I'm showing 367 free. Apps running: Angry birds RIO, Phone, Google Music (with music streaming currently), battery monitor, settings page.
4.0.1 is not memory efficient at all compared to 4.0.2&4.0.3. Not only are the newer builds more efficient with RAM but the size of the ROM on disk is much leaner.
After a reboot and once the dust was settled seems like I have 346 MB of free RAM, something you should try just to see how much you are starting with.
So I'm assuming you're on a build other than 4.0.1? I just tried a reboot and am sitting at 290MB free, I'll monitor it to see how long it takes to get back to the low 100's.
As for the Fantasy Football app, it does NOT have a widget. And apps that HAVE widgets, like Pandora, Evernote, Music, Docs, Soundhound, none of those show up in running OR cached apps.

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.

remove facebook, yahoo, and all other apps that runs on the background,
even if you have v6, the apps still runs in the memory
no matter what ram tweak you do if you have background hog memory apps and due to the limitation of our device you shall fail

I did not quite get that you said there, but I didin't encounter a single problem due to low RAM. Of course it can be because I don't usually run a lot of apps at once.
Thx but i very loves facebook app

if you are much conscious about ram then never use and go product they are the hogger beast
check every app's ram consumption then you their alternative with less ram consumption
if you love ics keyboard, then there are 2, one uses about 10 mb and other uses about 20 mb

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.
Thnks i use lessly ram now 121

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.

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:

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?
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.

i am with you on this issue. would like to find out for my self as well! constantly having to clear ram.
youtube, gmail, and browers = 2.1 gb / 3 gb ...
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.

Android is based on Linux. Android and Linux both run better when they use as much ram as possible. If you Google Android ram usage you can find a couple of interesting articles about this.

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.
I would be disappointed if its NOT beeing used...

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.

http://www.linuxatemyram.com/
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.
