I have Motorola Fire. Its a pretty good phone but have a constraint of losing out of memory at times.. The specs shows that it has 256 mb of RAM available but unfortunately i can see only 116mb total ,most of it already used up.. This slows my phone.. Is there any way to free up that memory?? or is it i am cheated?? thank u..
The rest of the ram is set aside for the OS. No way to free it up.

You could root your phone and then use an app like gemini app manager to stop apps you don't use, but were included on phone, from running.
Would free some ram up though maybe not a huge amount.

Hello, as we know, Galaxy S1 was advertised with 512MB ram, but in real there was only ~340MB of usable RAM! So i want to ask, how much ram is usable for applications and how much is free after fresh boot? Can someone check this? You can see this informations in task manager.
I think its about 800-850 RAM.
The original SGS had 512mb of ram as advertised. For some reason people assume that their phone behaves different than their computer. The operating system and everything like that needs to use the ram as well.
AS stated though I understand the SGS2 to have approximately 850MB of ram free after running the OS etc.
If I continually hit advanced task killer it will give me about 445MB free. In the standard task manager it says /833MB.
I don't really think this is all too relevant. You will never have anywhere near the maximum amount available just as you won't in a modern PC either and with phone OS's getting more power hungry and complex this is unlikely to change.
If the amount of ram bothers you check the video of the guy doing heavy multitasking on the phone and that will clear your mind.

Thank you for usefull information. I'm just interested in real numbers, because HTC phones have all advertised ram available to system, instead of samsung, which is cheating about this. Yes the OS is using ram... but from 833MB, not from 1gig. How can system use ram which is not visible to system? Android is linux, you can easily see how much ram is available and usable for system... it's 833 not 1gig. I believe that there is 1GB ram chip, but some memory is dedicated to other components. However 833 MB is really enough for mobile phone.

It did have 512MB of ram in hardware, but a pretty big part of the 512mb was actually dedicated video memory for 3d and movies. The Galaxy Tab 7" which was advertised with 512MB actually had ~600MB of ram in hardware, with extra ram outside the 512MB being for the dedicated video.
With the SGS2 it seems to be as the original SGS with dedicated video ram being taken out of the 1GB. It's easy enough to check by looking at the kernel config files. (And you can even tweak the numbers a bit to get a bit more free ram, as was done in the SGS)
Hope we're not heading down the old line of trying to run with loads of free RAM... I'm of the philosophy that if you have the RAM available, you should use it, rather than have to load things up from storage due to removing it to make a number bigger on a task manager...

Your philosophy is absolutely correct. In Windows that might be a good thing, because it starts buffering to the HD when you run out. But Android will just close some background processes automatically to clear ram as needed.

Unfortunately people these days only know about ram management from that poor excuse of an OS called Windows.... excluding 7.

Agreed, as long as there is a big line between FREE RAM and TOTAL RAM. More total RAM is always a very very good thing regardless of how good the ram management is.
This thread is about total RAM available to Linux/Android, so it's good imho.
Hi all.
How much is the actually Total RAM on Optimus one.? I have 74 used and 323 free . Totally 397
I remember having more than 410 MB Free Ram before flashing Franco's zram. As the latest kernel doesn't require zram. I removed it using the remove-zram.zip . Expecting to get Back the lost ram. But I still don't get more than 397 . Please help to get back all the ram and can any body please post their running apps screen shot
..to compare it with mine
You're lucky dr.notor isn't here or he would have come up with some sarcastic reply to this question.
Having 13 MB of ram less than normal is no big deal. The system uses the difference (512-397) for its use. And the system usage keeps varying, so you will never have a constant amount of free ram available. I seriously doubt zram is the problem. Also, our phone has tons of ram so stop obsessing over it. I'm quoting a paragraph from an article on lifehacker.com:
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.

thanks!.... I was just curious
I have been so busy catching up with all the amazing stuff Da_G has been pumping out (thanks!) that I didn't even take a look at this until now. I am showing that we only have 733MB of avaliable RAM. That is a far cry from 1024MB.
I am seeing 733MB w/ both Android System Info and with the built-in Task Manager.
Does anyone know if we indeed have 1024MB of RAM and... if it is just assigned else where?
Yes we have 1GB every phone has RAM missing because the system is holding it.
I remember one time the OS didn't support that much not sure if that's the case now but the phone has 1GB to my knowledge and.what I've read
sent from AT&T Samsung Galaxy Note Dual Core 1.83 GHz
Just like memory... Do we really have 16gb? Its never what they say... All marketing!

I have also read that is has 1GB everywhere, but missing 291MB seems like an awful lot.
I beleive my Atrix showed 897MB. I just seems like an awful lot 'mssing' w/ the Note.

I am with you on that! Makes me
I noticed the same, it's showing short but using the same app(system tuner pro) on my G2 it showed the correct 512mb.
It's not false marketing; it's fact. There is 1GB of RAM in the phone. I'm pretty sure the rest of the RAM is used by the GPU. My GS2 has the same thing, shows about 800MB of RAM available to apps.
What does it matter? I usually have 3-500MB of free RAM. Have you ever managed to fill the RAM with processes? Do you know anyone who has? Android clears old apps from memory even when there is enough free so I have never even come close to filling my RAM.
Graphics memory
As with any computer your phone has a gpu which needs graphics memory and because the gpu is integrated (SOC) it takes its memory off the top. This can be seen with any computer you have with integrated graphics it will section off some memory for your gpu.
As for the flash memory space many issues can take it down such as the file system, operating system, it just depends but trust me before the phone was turned on and android installed it had 16gb of memory and 1gb of ram
I'm about 100% CPU and GPU can't share ram as they do completely different tasks. They could have just added the cram and the ram to get 1GB though... But otherwise, the missing ram is from system tasks and the OS.

Do we have a reference or any proof of this?
And to the post directly above this, any computer that does not have a dedicated graphics card uses shared system memory, just like our phones. 733MB is just quite a bit away from 1024MB.
they can and do use the same memory because they are the same soc aka system on chip. all this is integrated.
So if you built a PC yourself and loaded it with 2gig RAM and booted into windows it would have 2 gig FREE memory?

I am not talking about FREE. I am talking about the system as a whole. Do we really have 1GB of RAM? Where it is being used I am not so concerned about at this point, but it may help us figure out if we do indeed have 1GB (Where is the remaing 291MB assigned).
The missing 291 is being used by android..to load the launcher Widgets and everything else in the background.

i have international version of note.its same way on this one.the missing ram is held by system tasks.as for 16gb storage memory.if you wipe all area on usb storage .u will have 16gb but not a working phone.another thing about free ram.dont use task manager to stop apps.all it does is make the phone lag.leave everything running.

I've got my device for one day already.
This is my first Sony Android phone and ... compared with my previous HTC old phone, Z2 is perfect.
However I find that the ram usage is terrible. There is only 1.1GB free RAM just after the device is booted up.
That means... the phone has used 1.6~7 GB RAM before I open the browser or games.
Quite ridiculous...
Is it normal? or what can I do for more free RAM
I don't think it's a problem but a good thing. Android has a smart/good RAM management. That means apps are kept in RAM until other apps need more. If you don't like you can try in developer option to play with "don't keep activities" and background process limit".
Right, you want your phone to use as much RAM as it can, this is a good thing. Also notice, the "unused" portion of RAM is also used to cache certain processes android believes you use often or will need. All of this is to speed up access to those applications as much as possible.
Take note on this
What is shown as free ram in linux is actualy freeable ram, your actual free ram is about 5mb
Linux has the motto of free ram wasted ram so when you have around 200mb freeable when your total is 3GB then there is a problem

Hi, i just wonder why this phone use ram so much high? (mine: usually at 1,7GB). At first time i use this phone it was used about 1.1GB of ram.
I'm trying to compare this phone usage with my previous tablet, samsung galaxy note 10.1 and it just consume about 700MB of 2GB ram it have and at first time i use it consume about only 500MB ram.
For your information, i use almost same app running in my booth device. But..
Why it come so much different? Z2 for sure have 3GB ram (bigger than other) but i think the system at least consume much more ram too than others. Are I'am right? Can u tell me what do you think? And tell us about your idle ram usage too if u can..

I think nothing of it
Linux is healthy to use ram unlike other OSs when ever you open an app your phone will free ram if needed, its not to hard seeing as how its managed
Your actual free ram is always 15mb but freeable is usualy always %90 of your total ram, ignore how much ram is avaliable
If you want to know more, look up linux ram management
Sent from my D6503 using XDA Premium 4 mobile app
Looking at RAM usage is entirely pointless.
Apps allocated RAM as they like but the operating system makes all kinds of predictions ahead of time to preallocate blocks of RAM to increase speed, eg when an app requests to allocate some memory the OS gets to instantly go "here you go; hehe sucker I already prepared that earlier".
The OS will more or less allocate as much RAM as you throw at it up to realistic limits. Eg once a tiny app has 1gb of ram the OS will take the educated guess that will be more than enough for it and not allocate any more.
If another app opens up and the OS is running low on memory it will rejig how much it has allocated to apps that never actually requested that much memory.
This happens on any modern OS and is why you should never really care how much RAM things are using.
In Windows under process manager if you looked you would find there is about 10 different ways to look at the RAM usage per app. Unless you really know what the numbers are saying they will all means basically zero in the real world.
Woa.. I never know it before.. Thanks for the info..

Skickat från min D6503 via Tapatalk
mine is usually about 1.5 to 1.9GB
keep in mind it caches apps too incase you reuse them, at the top right of the usage screen hit the menu to see the cached apps.
Mine is usually 1.5 to 1.7GB, even I don't run any app...
BTW, I install the app Clean Master ( like CC clean on Windows). And I always do clean Junk file and Boost ram once a day.
Is it good to use this app everyday?

If it's another generic 'ram booster', it's next to useless, but it won't be dangerous to use unless the app is programmed poorly. As others have pointed out, if there's no problem with the system (e.g. memory leaks), the RAM it allocates is used for caching apps so they may load quicker. Simply put, this behaviour is intended.
Cleaning junk files will probably have next to no effect on perceived performance as well untill you've hoarded enough junk files that your internal memory is almost full. But I see where you're coming from; it's very satisfying to see memory freed.
And while I am at it, I'd like to recommend SD Maid for this purpose. It's one of the few apps that actually do something useful. You can delete orphaned folders by apps that are no longer installed, delete junk and duplicate files, bulk clean app caches as well as optimise internal app databases.
