The specs says that this phone has 1gb of ram. Why do I only see only about 600mb in total ( used +free) in Settings/application?

Apologies for that and thanks for the links. I wonder how my Galaxy S with 512mb ram with ics rom ported from Nexus S can run so smoothly. Does android allocate memory depending how much maximum ram is available?

512MB ram is a decent amount, and the Xperia S runs smoothly. I think you should be asking in the Nexus S forum section.
The Nexus S is almost identical hardware to the Galaxy S in terms of soc / ram etc. The reason why the galaxy s is not getting ics is because the addition of touchwhiz on top of ics is to much for it to cope and samsung are not going to release a vanilla rom.

Mainly processor wise. Is this the fastest phone on the market currently?
I know the Xperia S is using a 1.5ghz dual core snapdragon CPU but is it as fast as the processor used in the Galaxy S2?
Memory and most other specs seem similar to all other new phones.
Although I did see recently that in a benchmark test it was quicker than the Galaxy Nexus for most if not all applications.
Just wondering how this phone will hold up after a year.

First year is OK. Arc came where they were dual cores and other stuff and it will even stay longer because phone's usability differs from person to another.
For what this phone is, it pretty good to me and what I have seen and after ICS hits this phone the true power will come out.
Very few applications are even designed/optimized for multi-core use, let alone quad-core.
While the lack of a quad-core will turn away most measurebators who want to buy the latest, glitziest quad-core model, from a software perspective there isn't much out there that will benefit from the extra 2 cores out yet for the next 2 years or so.
I'm a bit bummed about the 14.4 mbs d/l speed and the pathetic 2.1 bluetooth profile. They could have at least done 21mbs and Bt 3.0
Is it true this phone has 2gb RAM also?
I just checked my phone memory and it has 1.78gb free.
It's different from internal storage which I have 25.5gb free.

Hmm!
There is 1 partion for internal system storage, and it is about 2Gb, other partition we known as sdcard, ~ 28 Gb.
So i dont think the phone has 2 Gb ram!

Just like with PCs, there's a difference between internal storage and RAM.
AFAIK, the Xperia S has 512 MB RAM, of which about 340MB is available for applications to use while they are running. Right now, with the optimizations I have in place, I get about 370MB free RAM, which is a HUGE boost from the 100-140 I had on the Arc.

This is incorrect Xperia S has 1gb RAM. The 2GB partition is for app installs and the ~28gb is your internal sdcard storage. The 2gb and 28gb internal storage is just partitions off of the 32gb internal flash storage.

Yes, you may be right about the 1GB - I currently see 178MB used, 453MB free, so the rest would be used by the OS.
Still a massive boost over the Arc.

No this phone does not have the fastest CPU this is only downside to Xperia S. They released an excellent phone with last year CPU. The CPU Sony has is snapdragon scorpion or S3 while most phones being released in 2012 will have a snapdragon Krait or S4. The S4 actually performs faster than a Nvidia Tegra 3 quad core CPU which the HTC One X will have. If Sony released this phone with an S4 it would have best the ultimate android device IMO. However the Xperia S is still a good device that will last you a year easily and it beats a galaxy nexus which is the premium android phone right now as far as CPU.
Phones with 1gb of ram will have 256mb for dalvik virtual machine, so only 744 mb ram availble, and ram for system cache is about 200mb, that why you see free ram is about 400 mb.

hello,
i'm a new user of xperia s and i'm curious
And i would like to knows why there is only 697mo of ram available and no more ? (1go normally, and for example the galaxy s2 has 830mo available)
thanks for yours answers
The rest is allocated by the system.
some said it's for the gpu (as adreno 220 dont have dedicated ram), some said it's for the android os itself.
dunno for sure. but looking around i found:
sgs3: around 700 mB available ram
hox: around 900 mB available ram, but the free ram is about the same with sgs3 (or even less, bcause of sense ui)
so i think it's just the manufacturer interpretation for the used ram and free ram.
ok thanks a lot for quickly answers
Is there anyway to increase the ram availability like around 700-750Mb

well thanks for explanation.
only CM9 can improve amount of ram for user (i had that with girl htc wildifre with CM7)..
but not quitly sure if that is the same with SXS

Yes, AOSP should use a bit less RAM. Sony's skin is nicely optimized though.
I dont understand why company's are concentrating on processor amount,dual ,quad? ITS RAM that is so important, put 2 gigs in a dual core phone it will fly! any comments by devs on this would really help thank you

RAM isn't overly important in terms of speed. CPU is extremely important. Basically RAM just holds files that will be needed in the immediate future (or have been used very recently) to reduce read times on those files when they are needed. When it comes to actually running code, that is pretty much purely down to CPU speed. 1GB RAM is plenty to store a few apps and the background OS processes. When more is needed, older apps are closed (by "older apps" I mean ones used least recently). Otherwise, recently used apps are kept in RAM for quick switching. Unless you are trying to multitask in dozens of apps simultaneously, 1GB of RAM should be plenty for a phone today.
Both RAM and CPU has equal aspects on any device.
Ever tried playing GTA 4 on a PC with 1GB Ram and Quadcore CPU or on 4GB RAM with a SingleCore CPU...?
Both Ram and Cpu are important in terms of increasing speed.

The way I have always viewed ram is this; no, more ram than needed won't make your device faster, but it sure will make it slower if you don't have enough!

Awesome answer!! Thank you
Just like i thought!!!
"""""Under the hood, the Samsung Galaxy S III from Verizon Wireless is the same as the other US models. It ships with a dual core 1.5GHz processor and 2GB of RAM, which is meant to compensate for the lack of a quad-core processor that is found in the international version of the handset.""""""
JUST LIKE I THOUGHT!!! and above quote is from a major website!!!!!!!!!!!!!!!!!!!!
lol :victory::victory::victory:
More than 1gb of ram isn't needed. If you are on ics or jb, then you need a good gpu. If you are on froyo or gb, then you need a good CPU since they aren't hw accelerated.

Comparing PC with Android is a lil'bit out of the rails here. Even with one core and enough GPU combined with 4GB RAM should be enough to enjoy many things. More core's is good for multitasking etc. But when you think how many apps etc are optimized for those gazillion cores......

Its simple. Big RAM can hold more running apps or a single big app (more bunch of codes). In any case, there'd be high demand of processing. So, manufacturers can only add more RAM when they ensure that they have enough processing speed for better experience.
You can say, we have quad-core CPUs now, why can't we add more RAM like we do in PCs?
Well, the answer: Don't go for specs. Smartphone CPUs/GPUs aren't powerful like Desktop ones (despite same specs). There's power and heat issues, in fact.
Plus, Android and its apps are unable to use multiple cores with high efficiency (Intel advocates this; that's why it launched powerful smartphone CPU with 1 core). So, quad-core performs poorer than single/double core performance on PCs.
It limits the lifetime of a device since it cannot be upgraded and maybe manufacturers like that. RAM usually seems to be the limiting factor on phones running future versions of android. Its too bad it can't be upgraded like a desktop/laptop but thats the cost of fitting all of this hardware into a tiny phone.

AGREED! MANY DIFFERENT EXPLANATIONS! glad i asked ,all these helped. more ram would help but only to an extent. example if my wifes former htc design had a gig of ram it wouldn't have lagged so much running a single core 1.2 gig processor. FACT,so htc should have done it,it ran great till it attempted to multitask!:good:
Wasn't it stated during the I/O event that JB in general used less RAM and optimized apps better than the previous OS's so phones wouldn't need as much RAM as before?
It would be nice if JB or ICS had a timeout option for apps open more than a certain amount of time and would shut down automatically therein freeing more RAM. Obviously, it could be turned off or off depending on the user. Or if you could specify certain apps to close after an allotted amount of time if unused. Ex. Play store, calculator, calendar, SMS don't always need to stay on the page you left when you switched apps
Well, I've upgraded to this device from a Xperia Arc for some reasons. 1GB of RAM, one of the best dual core processors around and 1080p recording. Xperia Arc had only 512 MB of ram, leaving me with only 320 for everyday usage, and with GS2 I'm getting around three times more RAM, but since I've updated to JB on CM10 codeworx build, I'm getting less than 200 MB of free RAM. I know JB uses more resources to enable VSync and 3x Buffering, but is that normal? That's too high for me, and I don't see me back into the ICS roms.
Welcome to the club. JB uses more resources, probably won't change.

If you're asking if it's normal for people not to use dedicated threads for CM10 questions, yes, it seems that it is.
If you're asking whether it's normal that using a ROM which says:

Yes it's normal, but most of those RAM space used are for cached processes just to make things faster. More ram will surely be freed when you need them.
This is the only reason why even though the free RAM looks small at startup, you haven't experienced lite memory, or apps force closed due to low memory warning

I don't think, it's possible to have all 512Mb in use for your purposes. 512Mb is a summary capacity of RAM chips of your phone and part of that amount of RAM reserved for kernel needs(services,drivers, etc). From my experience:400Mb of availible RAM good enough cpacity for devices with 512Mb. There are 512Mb devices with smaller amount of availible RAM.
