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.
I know that this isn't a Q&A Forum, but we don't have any, we only have a post that no ones answer, i know too that this question is anwered so many times before but the answer i got was like "is normal", "an article from Xperia phones that explain some of that", but i still don't get it. System always get an amount of RAM needed for the correct working of all stuff. But why in other phones (even with the same chipset) that doesn't happen? And why we can't see where and how the left memory is been used by system? Normally i've seen before how RAM is reduced to share it with GPU, but in ICS our GPU looks worst than on GB so RAM definetely isn't on the GPU, so is good that all of us reach the point of this, i get some screens from other devices and i will posting this in a little bit time.

Its ok.....i have also read similar thing in xperia topic. But i just want to ask , why does this not happened in the non G version. If it was reserved by kernel for graphics and gpu use then why the graphics performance have become worse in ics....???? All is clear that samsung is not treating the both sets similar only selling them at similar price.....poor samsung .

Oh yes it has same as our..... but it has a better display of 720p res. So what does it mean...??? The cpu has to work more on the extra pixels . And the thing that ram is reserved for graphics sounds correct here because more pixels more load on gpu and ram. But did u noticed the same processor and ram having moto razar hav nearly 800mb available ram. I just can not understand why the G version has been locked with ram and not the nonG version , still while launching the G version Samsung said that both devices are similar in performance. But we all know about it , nothing to say here.
And the most important thing is that Motorola Atrix2 is available @22.5k which have everything same except display, and also gnexus in some places @24 k yet it have more powerful cpu and higher resolution. . ...and what we r paying for i9100g........27.5k . Samsung is only cheating Indian users, even they have not specified on the boxes whether it is G version ( saw many issues like that on google ).

What if I told you the 680mb ram is just a display error across the device.
Have you ever exceeded using 680mb ram on the phone?

I regret buying this phone, if you ask me, not because is Samsung, just because it's Android. I really don't understand the logic behind a mobile OS that uses lots of RAM in a device that obviously does not have great battery. I had at the time an iPhone 4S and my SGSII simultaneously, so I got the chance to test them in RL. Even iPhone having a less efficient display (LCD vs AMOLED) and a smaller battery than the one on the SGSII, in actual daily use, iPhone seems to handle its RAM way better than any Android I have tested. The problem in many Android IMO is when in idle, still consuming a lot of RAM that greatly affects battery.

so u think more free ram is better ? its maybe right in ios but its not in android. ram is born to be used.
Dont think ram consuming cause battery drain.

Straight answer below.
Scenario: An Xperia™ Phone.
"Now, let’s look at how the RAM is used. Out of our 512MB RAM, about a third is used for functions that require a dedicated memory slot to operate fast enough. For example, this is the case for certain multimedia functions. The remaining space, which is at least 340MB, is reserved for the Linux user space, as required in the Android Compatibility Definition Document (CDD). Within the Linux user space, functions like the activity manager and Home screen app are running." (Sonymobile, 2012).
Picture illustration as follows:
This partitioning more or less applies to all other manufacturers' devices, thus explains why the promised 1GB in our device is not entirely visible to us.
As to why different phones with the same chipset has different amounts of RAMs (i.e. Samsung SGS2 VS Motorola Droid Razr & that Razr appears to have more usable RAM), it simply goes back to the reason:
Samsung SGS2 consists of more system functions thus uses more more RAM than compared to that of Motorola Droid Razr.

this is not a new question, and I believe it is one of the most frequent questions and I was convinced with the giving answers but after getting my nexus 7 I am looking for some explanations.
why do we have low available RAM.I usually have 200 or less free RAM while my nexus 7 have ~ 500 free RAM. and even the total amount of RAM (used and free) together is about ~650MB and not 1GB, I have read that because delvic catch and other system process uses some RAM, but again my nexus 7 shows total of 1GB RAM (see screenshot attached).
so is this a problem with xperia s itself or is it ICS and this will change with JB
I know that android can free RAM when required and I know that the system using some and I shouldn't care, but using heavy apps and live wallpaper just eats the rest of the RAM and the phone become laggy until I make a restart, then it becomes fine.
any explanation?
It is normal. Live with it.
It's normal, it's not the same as windows, or other OS, I remember I've read in some place that this 'low free ram' is good, because it will start faster the most used apps.

The xperia have more stuff always running in the background so it eats the ram up if you take off stuf like timescape and yada yada might make a difference..

A) There is no way that nexus 7 has 650 RAM
B) We only have 700MB vacant RAM.
C) I uninstalled all the bloatware, there are some more com.bull_****.android processes that can be killed.
D) I made some changes in the heapsize... by this tutorial. Works in JB as well.
E) All of the above?:fingers-crossed:

Nexus 7 shows @GB RAM because Tegra is way smarter than Adreno when it comes to graphics RAM.
is there any apps can stop those useless apps to autorun its own or auto startup when phone turn on??
i tried:
autostarts
startup manager
autorun manager
easy app lock
all these doesnt work on my xperia s... thy work in my xperia x10 before... (p.s. my phone is running ICS and is rooted...)
not sure what difference it makes. My phone sits on 105MB free most of the time. I have no lag
what i know from the HTC One X is that tegra 3 GPU is sharing the memory in real time, not partititioning it like the others. only a small amount is saved for kernel so it was showing about 900 Mb of ram. i dont think it is good idea with all that single memory controller. but anyways, tegra GPU is generally sharing the graphic load with CPUs. this is why tegra optimised games make CPUs jump to max even the other devices can handle them easly with chainfire 3D.
and the reason it has more free memory everytime is that, the multitasking is less agressive in quad core devices due to the possible battery drain and heating problems. and this makes me think if upgrading to quad-core is a bottle neck in software with todays battery and 40 Nm technologies.

Quad core is just overkill on mobile. It needs a different approach. OMAP5 is quad core, but the two 'main' (faster) cores kick in dynamically, and most of the system runs on two 'coprocessor' (slower) cores. That's an interesting concept because it can dedicated two cores to a single application and keep the system running in the background.

The problem is the phone does report less than 1GB and people are used to the likes of windows reporting the amount the actual installed RAM not what is actually available for use.
Sick of hearing it or not you better get used to it because unless manufacturers or Google start displaying the amount of RAM actually in the phone the same question is going to be asked for ever more.

No if u use PC with non-dedicated gpu/VGA. Imagine if people complain their 2 gB ram laptop has only 1.5 gB in the Windows. There are a lot of laptops saying that they have 2 gB ram (in their advertisement ), yet the fact is they only have less then 2 gB cause of the sharing of gpu.

Lol.it's different case. It's because the os (32 bit) doesn't support more than 3 gB ram. But there's a hack to make the 32 bit windows use more than 3 gB of ram.

I'm betting some of you have a Nexus 7, did you notice that the free ram is about 950MB out of the the Gig that it comes with?
Why do our phone only have like 720MB available if the tablet has so much more?
Both the tablet and our phones have 1 gig, so what gives?

Of that one gig of ram there is firm ware and the OS and some preloaded apps on the Nexus 7 on your phone it is about the same but with a skinned UI and then the carriers bloatware on top of that. It all takes up ram, so no bloatware or skinned UI gives you more ram on your Nexus 7.:good:

Its full ram is used to play apps and games on your Nexus 7.
Also...the nexus tablet doesn't have a cell antenna...So no mobile data to keep track of, those services are running on your phone all the time
A friend of mine bought At&t Galaxy S3 and it suppose to have 2gb Ram but when i check the phone it show 1.6GB ram and only 1.03gb available. so i guess it is used by system or graphic or something. Just like the computers that doesn't have dedicated graphic card so if your computer has 4gb ram you would have 3gb ram available the rest is reserved for graphic. i am just assuming that the same this is happening to our phone. if i remember correctly when i had CM9 and when i went to setting, about phone it showed only 768mb instead of 1gb.
I have all 16 on my computer.

My only gripe with the Note is the 1GB of ram. You only have about 350mb available and as we all know, Android caches stuff you run, but most of the time your not holding many apps in that free 350MB so its always restarting apps anyways. This phone (any ICS phone really) needs 2gb of ram.
I've used the S3 and yeah, its super snappy because so much more stays in all that extra active ram... Samsung saw the light and added extra ram, I hope this is a new trend... How do we get a 2gb chip soldered in place of the 1gb chip

That's a pretty good trick then. That alone would make me be sure my next phone was a Tegra 3. Not for the speed, but you really need more ram...

You could always get the S3 or some other phone with 2GB ram.

I'm not giving up my Galaxy Note's huge screen Hoping the Note 2 gets 2gb of ram
Our phones are deliberately under-clocked to 716, some may say it's for the battery life but I think it's because the higher clock speeds lead to shorter phone life. Using custom kernels, you can clock back up or even overclock. The payment is made mostly in battery life, but if your ROM has a memory leak of even the smallest size, overclocking will open the dam and the phone will suffer for it. Also, the phone will run at a higher temperature, which for sure will end its life much faster than leaving it at 716. This is the way I feel about overclocking: If you get the performance you want, leave it alone.
Wtf??
Clock speeds have not a single thing to do with ram whatsoever
Overclock is for the cpu
Aside from the OCD of the available RAM number, how has this negatively impacted your user experience? Are applications running slowly or crashing?

Apps are continuously closing and having to be relaunched (slower). Back in the older days of android where apps were 20-30mb it wasn't a huge deal, but some of these new games/apps take up well over 100mb of ram. everything else in the background is closed as it needs to make room..
Would be nice to have more active app space for a much smoother "multitasking" experience.
Sounds like we need a high speed dev to create some software to access the SD card and use it as ram....
Is that even possible ????...Hmmmmmm

Are you running more than one game that takes 100+ MB of RAM at a time? Do you jump from one game to another in the middle of action?
Sounds like you want to just want to be able to adjust your LMK settings. I don't believe there is kernel that lets you do that yet, but I'm sure there will be eventually.

not quite.. SDs speed of 20-30MB/s is a far cry from the 1GB of LPDDR2 "333Mhz?"in our note with a transfer rate of 5,333MB/s
Hi people, just a simple question that hope has not been made, do you think, in a short time (few months) 2 GB of RAM will be required for our devices to work well?
The most important is smooth and stable, higher RAM is not neccesary. :laugh:
Probably as tech gets higher, more ram will be required for later games and applications.

Cellphones today are the same as computer is... the higher hardware it would only be required to those who uses heavy features, like games and developing programs.
So, if you want a device just to basic use, you'll not need high spec cellphones.
It really depends on the usage, but there will be a lot of resource-consuming games released soon.
Some custom roms like miui also take a lot of memory! 1GB is getting short...

You don't really NEED 2GB of RAM, but does help. Better multitasking, mostly.

me personally i don't think that phones really need 2gb like gagdude said. I think if you have a kernel that makes the phone run faster then not necessarily 2gb is needed but helps alot.
Seeing phones like the new Nexus or the Galaxy S3 Alpha are coming out with two GB... I dont know if there will be apps or tweaks like that new one on the S3 Alpha that will not work well in our 1 GB phones soon.
i have a htc desire with cm10 4.1.2, it only has 576mb ram, but still kind of smooth, so 2gb is not necessary, but still more is better, because it will be more smooth, espicially when you playing games.
I don't think it's necessary and yeah you guys are right phones are like computers.
HD Screen
Quad Core
2GB Ram
Powerful gpus
If cpus would be x86 and with a mouse and keyboard you could get a fully working windows 7 on your phone. Even most of the computers at schools and libraries are not quad core.
I think ubuntu realized that and they are developing a fully functional ubuntu for phones with two and more cores.

Personally, I feel that 2gb ram is needed. Reason being that stock s3 uses around 700 - 900mb of ram. Of course, you may still say that you can install custom rom and decrease its usage to maybe 500 - 600mb. But if you run a lot of apps, it will eventually use more than 1gb of ram and the remaining usage will be send to and forth the swap(slower access).
Despite having zram which improves performance for devices with low rams, but ram is still faster than zram so having more ram is indeed better.
With a device that has to swap to and forth the swap and ram, battery life will be reduced and the performance will not be that good as the instructions of the code inside the ram has to be done then only it can be swapped with the instructions inside the swap and so it reduces the performance(in theory, you may not feel it unless you run something i/o intensive)
Go read up more on ram, zram and swap and you'll get it why I'd said to get a device with more ram.
Platform fragmentation on android will surely slow down this process. Also the maximum heap space available for a Java application (opengl textures and native code are excluded from this limitation) doesn't make extra RAM so important for many apps.
But for sure I wouldn't complain if my phone had more RAM.
1GB is enough. 2GB? You will play Asphalt 7 & Modern Combat 3 at the same time?

Not only your device is multitasking, but also you are multitasking.
