This phone has 1Gb RAM, right? Why does Task Manage show the RAM usage as 271MB/833MB when I have nothing running?
I understand that some of the RAM is used by the system, but surely that's what the 191Mb is being used for? (1024 - 833)
What's using the other 271Mb?
The system can't be using 464Mb RAM doing nothing... Am I missing something?
!
My SGS2 have always between 600-650mb ram free ! your score is not normal...

Is it normal that the T-Mobile G2 Touch only shows 190MB ram max. in apps like mini info etc? I thougt this must be 288?
Just like a computer, some of your memory is dedicated to system processes. Mine shows the same..
How much free ram memory xperia mini have ?
And does it have 512mb total ram or something like 418mb ?
Story is the Xperia has 512M of RAM, but 177M or so of RAM are taken up by the O/S. Leaving something along the lines of 335M free for other apps.
I don't know why all the programs that report memory don't show the memory reserved by the O/S.
Would be interested in knowing if such an app exists.

can u post screenshot of ram memory status ? so if i'am understand u, xperia have 335mb free ram with stock rom ? thats cool

That's the theoretical amount of memory, when I run max kill, I end up with 191MB.
If you go by the utilities they show you total memory its 335mb

ok, than it have 355mb ram not 512mb is 191mb of ram enought to run hd games ?

It's truly 512MB RAM, but the operating system (Android) also occupies RAM, for example in panamamike's case, the OS uses 191MB for its running so the amount of RAM left for other programs is about 512 - 191 = 355MB RAM.
I haven't tried any HD games but you can watch these videos :

Actually, the math goes like this.
512MB total - 177MB [Hidden by Android for system] - (166-170MB) [Android O/S apps] 22MB [Kernel] approx 143MB available to the user. Max Kill, kills some of the Android O/S stuff, but it starts right back up automatically. I don't know enough to determine if I can really turn some of that stuff off, but ATM I'm just letting it go.
Also note, if we could root the phone, there are applications that SE has installed as part of the O/S that could be removed to free up more memory.
It's a bit disheartening to see such little memory truly available. I don't know what typical HD games need to run.

i don't understand, if system hide 177mb ram for system, why he(system) double use ram memory ? 1. 177mb and 2. 166-177mb(for os and apps) why ?
never mind, thast cool phone..
Most apps/games store the big files /data on yer sdcard. The app needs to have this feature implemented.

Well, we all know the ray has 512 MB of RAM built in. But if you use tools like Android Assistant, it tells you you can only use about 332 MB of it. I searched in other forums and found out, the "hidden" part of the RAM is reserved for the gpu. My question now: is there a way to reallocate the RAM and get some of the reserved available for user apps? Because i constantly get freezes wit oom.
I dont how to do it , but i am also disappoint when i saw ray has only 315+ RAM , sony site says ray has 512 MB
I am sure if we try to re allocate it we will get problems , why not you try cyanogenmod ?
it is faster and less RAM intensive
i am running on cyanogenmod 7.2 , but if i use launchers like spb shell 3d , my free ram, even at reboot, max caps at 110 mb. thats nothing.

i think is possible but it will be worst! most of the phone speed is given by the gpu (example samsung galaxy ace has 800MHz but lower gpu alocated memory and the phone speed is a disaster)
I think the only way to 'gain' some extra RAM is enabling SWAP.
On my old samsung, I once had a swap partition of 256 to extend the memory.
The good: you have real extra ram
The bad :
-swapping is slowing down the phone, as the sd-card speed is never sufficient.
-SD-card will die sooner, as you read/write a lot to same partition.
So swapping is not advised to my opinion, and others.
Some way to make some memory free (and speed up your phone) :
Use a clean rom (like 4pda.ru) and with the "autostarts" tool, try to disable android apps that automatically try to start itself at boot, startup or other events.
I found out that a lot of android apps try to start themselves even when you plug in the power cable (google maps for example), or connectivity changed, application installed etc.
With the autostarts tool (or rom toolbox) you can influence these triggers to prevent apps to startup themselves in the background.
I am running omega Rom v13.and siyah kernel 1.5.3
I always observe my task manager and observe that my ram usage cannot higher then ~700/833MB?
It kills my apps if usage is higher then that.
I mean why? I should be able to utilize all the ram to right?

You only have this much ram, the phone needs its own ram for graphics, buffers, os etc. You can get more ram from siyah kernel using swap but this has disadvantages

I am not referring to the available ram.
Yes, I know system reserve some of the ram which left around 833MB for user.
and with touch wiz and other background process holds the ram, I see roughly 500/833 left over.
Now the left over is my ram for my advice apps, isn't it?
This is my question now :
The left over ram which around 333MB, I can't utilize all, I can roughly use up to 200 MB, and if over, my apps start killing
.why I can't utilize all of the left over ram?

Android its based on linux which hates to leave memory unused, it therefore uses free memory ssh buffer cache to speed up I/o.
Found this, you can run free -m from a terminal emulator

Even when i open my phone i have 160 free ram out of 340 ram without any program running!is there a way to free up more ram?
P.S. sorry for bad english!
Change the rom u're using =)
I Prefer GB roms because they're faster than ICS
You can use a program, which will be manage your RAM. I use ES Manager. When my phone is lagging, i click on widget with this program, and i have clear unuseful apps from RAM.
160 mb free ram not enough? Then u sure never feel the 50 mb free ram from low end devices don't u?

What device are you using
When I'm killing tasks on my Xperia Ray and I see 160 mb free on RAM, I start dancing in circles:silly:.
Is your phone still laggy with this much free RAM, or why are you asking this

Free ram is a wasted ram
Sent from my Xperia Ray using xda premium
^^Exactly.
Even if ram is 160mb, your phone should be quite smooth. Free ram only plays an important role in benchmarks, and benchmarks don't mean anything. Real experience and performance is very important. However, if you want to free more ram, remove unnecessary system apps, using init.d scripts, build.prop tweaks, custom kernel, better adreno drivers etc. After doing all this, I always get 200mb+ free ram in stock ics.
