[q] Available RAM

Can someone figure out, on the LATEST FIRMWARE, how many mb out of 1024 are actually usable by the system?
Quadrant>system info is a good place to check.
iconia has 745 (really good imo)
thanks.

The newest firmware 8.2.3.9 has 746100 kb

Not really, it totally depends on what's running on your tab at the time, it's not a set number. Everything is available it just doesn't show what android itself is using.

We are not talking about free RAM, we're talking about RAM available to the OS. This will be the "big number" in task manager or as Quadrant reports it. Useful to know because different devices can have the same amount of physical RAM installed but various amounts reserved for GPU, camera etc.
Also, 746100 kb = 728MB RAM. Less than Acer? Strange.

Why does my One S have much less space than advertised

I recently bought a One S and one thing that has really been bugging me is the fact that I have much les storage than advertised. It says that you get 16 GB, but the actual amount is 12.14, and
2.21 of that is internal memory so I only actually have 9.93 to store my media. Why is this? Also it says it should have 1 GB of RAM but task manager says I only have 650 MB.

16 GB storage is partitioned and some RAM is reserved for the system and the GPU.

First off no hdd or flash memory is ever 100% as advertise because its been formatted to run. That's why there is only 12gb instead of 16gb. And that 2gb is the space dedicated to app installs. And the remainder is for you to do with however you please. Music, videos, extra game data (like many of gameloft games where you need to dl an extra 500 MB or so) or whatever you else you want to throw on other then an app install.
When you see an app in market and you download it and install it, it goes directly to that 2gb partition. If you download an app from a third party website it first goes to the 9gb space and once it installs it, it installs on the 2gb and all you need to do is delete the original dl .apk or keep it as a back up.

The above answers covered the answer so no need to reiterate but I just want to opine that you should consider yourself lucky, HTC doesn't rape you like Motorola does. On the Razr and Bionic, they are advertised as 16gb internal but only 8 is accessible to the user. They allot 4gb for apps and 4 for the OS. Bonus for them is obviously expandable memory.

System takes the resources
On many phones the preinstalled software takes a lot of space. I would recommend to install another ROM. I always do that to get rid of the software I don't need.

Ok. Thanks for the help. But what about the RAM? Shouldnt all of it be available?

As already said, some of the RAM is reserved for the system and GPU. For example my HD2 should have 576MB RAM but it only has 411/403 (depends on the ROM/Kernel I guess) because 128MB is for the GPU and the rest is used by the system. I never actually get that much free RAM (I never get more than 200MB free, and that's only on startup; normally I have around 130MB free) but at the same time it's never really been an issue.

Ok. I just though that everything was shown together because I always have 500 MB of RAM used even with all applications closed.

The phone will still reserve some RAM for itself, and that is not the best indicator of RAM that's actually in use.

HTC One S is a gorgeous piece of hardware. To bad they didn't add sd card support...

System software installed on separate partition usually. So removing them will not add more space to the user data.

another RAM consumption question

I am wondering if anyone of you feel suspicious about RAM consumption on android?
Here is an example:
Galaxy tab 2 7" listed with 1GB RAM, but when viewed with stock task manager in RAM manager section, the RAM available is not 1GB, but rather on some 687MB. Furthermore, from that 687MB there is some already used by apps. Even on newly bought device with no open apps, the amount of used RAM is around 200MB, so that leaves only approx 487MB left. Even after using task killers, there is still hundreds of MB used RAM
When I search for why the RAM is not 1GB, people answer its because its reserved by android.
When I search for why there are used RAM when there is no open apps and on newly bought device, people also answer its because its used by android.
So I would categorize the problem as "the missing RAM" and "the used RAM" and ask these question:
1. If the "missing RAM" is reserved by android, then what is using the "used RAM"?
2. If the "used RAM" is used by android, then what is causing the "missing RAM"?
Does that means android double use the RAM? or is it something else?
Please enlighten me.

Great question, and I have been wondering the same thing. :thumbup:

The problem with me is somewhat like you i found with stock rom that have alot of bloatware that i have about 680 mb after installing cm10 which do not have bloatware at all the same amount of memory is found !!!!
Sent from my GT-P5100 using xda app-developers app

It's easy in the world of IT 1gb is never 1024mb its 1,000mb in most cases(You can actually see your computers harddrive where they say 500gb = 500,000MB)(but it will probably maximum 998)Why? in the factory where these are made they cannot achieve 100% "capability" And where is the missing 300mb? its reserved for the ACTUAL Android system.In the task killers you can see that there are some apps running(samsung touchwiz,system-apps(not google) Which MAINTAIN the system ,and you can also see that the google apps and some other(fb,twitter etc which needs to check the intertnet to get notification etc are running too.Now to increase the ram you can install a custom rom/kernel to remove somethings(for e.g touchwiz) to get more RAM.
Now dont take these notes to serious I'm not working in these factories,places where they do this.But this is MY theory.

Tab2 should have 1 gb ram right
Galaxy s2 should also have 1 gb ram right
So why the hell when i install cm in both ram in s2 is 827 mb and in tab2 is 687 mb it is driving me mad !!!

I do realize 1GB is not 1024MB, but at least task manager should show something around 900MB like you said.
For the Touchwiz theory, I also think that it might be the culprit of the "used RAM", but i don't think it would be that much, but that's because I'm not including google apps on that. So i think your theory might be right.
Selim already answer the "missing RAM" part, it is the same amount on custom ROM, which means they DO reserved by android. And that leads to how much is the "used RAM" part, is it more "sensible" without the bloatware running around?

There are settings (in Android we call them "minfree" settings) to tell the system how much RAM to leave free and available, but the rest is designed to fill up as fast as possible and stay that way.

For most android devices, the true available RAM is always less than the stated figure, like GT2 has only 687MB, HTC One X has 976MB even both devices has 1GB RAM
Those missing RAM are not stolen, instead they are reserved by the kernel for hardware of the devices. Don't blame anyone for this, this is crucial.

That is an interesting concept of memory management.
FYI, I'm not freaked out, just wondering where the memory goes, is it effectively used or eaten by some "rouge" apps.
Thanks anyway

However my Galaxy Tab plus with ics had about 800 mb ram in the task manager. Now (yes, my gtab plus has been stolen... grr) I have the tab 2 and I see only 687. Really strange, don't you think?

RAM HELP
can someone who has well experienced with different ROMS for tab2 7.0(p3100) help me??
i originally had ICS 4.0.4 which displayed around 680 MB ram, then upgraded it to 4.1.2 jelly bean which displayed me 770 MB RAM.
i though as custom ROMS have seldom bloatwares, atleast they should display more memory, but to my surprise i found 691 MB RAM on the latest nightly build of Cyanogenmod 10.1(jelly bean 4.2). I ve not used the AOKP jelly bean ROM due to limited internet(downloading) at my place.
as i am having a LIMITED FREE INTERNET USAGE, i am not dowloading more ROMS until some one finally helps me with the fact that
"WHICH ROM DISPLAYS MORE MEMORY FOR TAB 2 P3100??????" so that i can download it the next month or via some other network

I don't think you for it, the missing ram is the system. The tab has 1 gig to start, but whennyou fire it up, the system has to use resources. The same way a computer says it has 2 gigs, but if you check, it is lower. The reason this changes from rom to rom is because each system has its own ram management. Does this help?

[Q] Ram reported as 770MB in the about hardware section

Why would max RAM be reported as 770 MB if the total RAM is 1 GB? Even using Android System Info app it says the same thing. Thanks.

I think 770MB is what the system has access to.
Though the phone specs say 1GB

I thought maybe the AT&T One X got screwed versus the international one. However, I just checked a Verizon Galaxy Nexus and it only reported 694 MB. It must be the missing 300 is tied for the kernel or other critical os items. Thanks.

[Q] Internal memory partitioning

Hey everybody,
I am considering getting a Moto G, but i was wondering how the internal memory is partitioned, and how much of it is available for apps and cached music on the 16G version. I read somewhere that on the 8G version, the internal memory in split into 4G system memory for the OS, and 4G for user data. But i could not find the memory partitioning and size for the 16G version.
Anyone with a 16G version who can check this out for me?

I have 12.92 gigs of space before user apps etc. I'm still on the 4.3 ROM, haven't received the new 4.4.2 OTA upgrade.

No partitioning on 16GB. You can use it for whatever you want.

Moto G 8Gb : Too few (APP) space..

My Moto G 8Gb is really fast...and perfect except for 2 (common) problems, the most important is the FREE APP Space :
1st - impossible install APP except fro Play Store : NO Amazon app, NO AppOfTheDay free app,..
2nd - 5Gb FREE that with a bit of music (2Gb) , Sygic Navi (600Mb) and something else means only 1 Gb for free space ,,,but the worst info is that,
if i check with DiskUsage it says i have :
APP : 1193 Mb --> when i go to install a new app (only 11 Mb) now it says "i have not enough free space" !! (
SYSTEM DATA : 614 Mb
Really too few space..

Got the same problem.

I have a 8gb and I'm thinking of changing it now for a 16gb.
I don't have any music or big game apps just will have a few average apps and photos. Do you think 8 will be enough?

8 Gb. is enough for me! Like you said, i just have few average apps, i am not the person who's taking a lot of photos and i don't have a lot of music neither, so i'm fine with 8 gb ñ_ñ

I'll might stick with it then.
I'm the sort that downloads a app and if I don't like I delete it. I can't see me having more than 20 + the pre installed apps at any one time. but maybe a good few photos.

For a few big apps , couple of songs and photos 8GB serves well
