I have been baffled by this since GB era, coz I couldn't figure out why the ram don't add up.
In JB, Settings > Apps > Running, shows a list running apps. you also have an option to see a list of cached apps.
Below the list is a bar graph clearly showing what's free. However, it is about the used part that I don't quite understand. From what I can see, the running apps only make up part of it.
In the attached email, I've marked with red rectangle for I don't know what, yellow rectangle for what I think is the running apps, and purple rectangle on the right for free memory.
Can anyone tell me what the red rectangle represents? Is it memory used by the system?
Hi
Are u just asking for information purposes or is there a specific reason why you're asking.
Battery drain?
Slow processes?
Random reboots?
What ROM are u using?
Im just curious because it can help someone with their response to ur question.
And that is a cool font ur using. Did that come with the ROM or did u apply it?

short answer: slow processes, launcher redraws, laggy operation in general on Jellybro and XenonHD.
with ICS and a few initial JB roms, I totally forgot about this question at the back of my head.
But, I am on Jellybro (CM10 based) and also trying out XenonHD, with both installed after formatting/wiping data, system, cache, and dalvik, and I experienced redraws on launcher and lags in operation in general after a few 10 hours or so of system on time. I checked the running apps, and I saw that the left red rectangle is eating up almost 70% of the ram and only 30+mb shown as free memory.
running app list didn't show anything strange. It's just the free ram is extremely low.
So, I was wondering what the red rectangle area of the memory represented.

so, the red rectangle is showing what the system is using up?
I always thought system area of the memory was allocated separately and system was restricted to operate within that area...but from what I can see the red rectangle area varies from about 40% to up to 70% from what I can judge with my eyes...
but wait, I thought Nexus S came with 512mb RAM, of which part of it is force allocated to the system and not usable by user apps. So, 288mb is additional unusable memory? that would mean we only have about 100+ ram for my apps. that stinks... hm...

With such a problems u might try Jelly Belly 1.5.1, I've been running since release and never had such a issue, everything is smooth like butter...
Regarding low memory, don't worry about that, when i fire up all my apps like stock browser, maps, pulse, flipboard etc, i have around 50mb free but still quite smooth.
Btw i tried Xennon and few others and there were laggy like hell on my phone.
Maybe i or my phone, or we both like stock feeling....

Ur App "swipepad" is a memory hog according to reviews.
try the ROM bare boned... if its still lagging then try a different kernel. Or try for different ROM that does not lag bare boned.
Then add ur memory hog apps one at a time so u can pinpoint the main hog
Good luck.

swipepad takes 6~7mb. never saw it go beyond unreasonable point.
besides, it doesn't count into the red rectangle on the left
as said adding all app memory use in the list does not add up to 300+mb it says is being used...
anyway. got on slimbean and everything smooth and good~
some says it is a cm10 issue and jellybro being kanged cm10, same problem.
but c'mon swipepad is good! can't live without it anymore....

In application tab, it doesn't show available memory.
That number is "you can get this amount of ram by killing apps(background running...etc)"
When u using it long time, RAM(that value) reduces, so u have to reboot..
Otherwise, How about buying GNex..

...let me see if I understood you correctly.
do you mean that 288mb in my screenshot is what I can get back when I kill all running apps? That means, 288mb MUST equal to the sum of memory used by all the apps in the shown list.
Or, wait, do you mean the numbers next to each app in the list means how much memory will be returned when I kill that app? that just means that the app is taking up that much of memory...
in my screenshot, I have 3 rectangles. maybe they are not clearly contrasted to notice. red rectangle on the left, yellow rectangle in the middle, and purple rectangle on the right.
- purple rectangle on the right seems pretty obvious that 188mb of memory is currently free, of which some cached apps reside at the moment.
- yellow rectangle in the middle, I am guessing it represents the portion of used memory that the apps in the shown list are using.
- reason for this guess is because adding up all apps in the list does not equal 288mb.
- red rectangle on the left, I am guessing it represents OS using up.
- the 288mb seems to represent the SUM of yellow and red rectangle.
- so, 288 + 108 = 396mb is the total usable ram for my phone.
my question is, is my understanding of yellow and red rectangles correct? if not, I wanted to find out from you guys...
oh, and for those interested more in what font that is in the screenshot, the filename says fbplum...
there are other things taking memories as well, like scrolling cache, so if you can reduce that and other things, you get less memory hog, but slightly more laggy, and that's part of the reason why iOS doesn't support real multi-tasking.

512-39x=hardware takes ur ram, camcoder, radio...etc
39x=total ram for software
Blue rectangle=ur OS takes RAM+apps you are running(servies maybe..)+Loss of RAM by killing-running apps(reboot clears this)
108mb=Max. Amount of ram you can get when you launch other heavy apps(killing background cache)
For me, cm10 jellybro(0810) works best, but according to benchmark, ram score is little bit bad..(Maybe it's meaningless..)
Let's just wait for rasbean jelly..

on a mobile device with 512mb ram, of which only about 300mb is left available for OS and user apps, full multitasking is not a good thing. 'coz it requires users to take memory management into their own hands.
on newer devices with !GB+ ram, I guess Android OS will do just fine to manage memory.
anyhow, iOS can also run out of memory, right? requiring user to manually remove cached apps from memory, otherwise even iOS becomes laggy, is what I hear from iPhone users.
...and that's coming from an OS where tons of money went in to make smoothness and feel as best as possible~... iOS still gotta improve I guess.

Task MAnagers!?!?!
I'm not sure if i am 100% right about this maybe won of the senior members who does know can enlighten us on this...
But I remember reading somewhere that task managers some times can hurt your phones RAM usage. I don't use one anymore unless it comes stock. and then I rarely find a reason to open it on mine. In standby I am running around 80-100 with 200-300 of freem RAM so with the SGS4G i don't think i will find a reason to use more than the stock utilities. I somtimes will installl a tool to monitor the RAM to see what I'm usin but every once in a while I go through and uninstall anything I don't need right away. I figure ussually being in good internet coverage I can always put something back.
So does anyone else know about wether or not the "Task Manager" could actually be a tantric in some cases?

So widgets are the ram hog on this phone? I have been constantly clearing ram in the task manager to help with speed. I only run clock, battery, and calender widgets on my device. Are they enough to boost me all the way to 240+ even after a RAM clearing? Considering the age of this thread is this still the case with new ROM's that are starting to roll out? I'm still stock, and very noob to android devices, but the urge for mods is growing given the positive responses to them.

You shouldn't have to worry too much about RAM usage. A lot of it used by the OS. But yeah widgets does lower it and whatever app you're using. But I hope you don't resort to using task killers just to save 50mb's of RAM. It's there for use and shouldn't be looked at too much.
Mine shows about 400/626, but haven't noticed any big difference in battery drain when it's at 300/626.
Simple answer....everything hogs ram. The best way to tell what's worse is settings » applications » manage applications and watch your ram usage when you have certain things running. You will notice what is hogging more than others.

Thank you for the info everybody. Been ruinning just fine all day with the ram almost maxed out, hard to break that task manager habit though lol. Goona keep reading before I root-flash-mod need to make sure I get it right the first time.
On the moon our weekends are so advanced they encompass the entire week
Samsung and Tmo set many bloatware to run ALL the time and hogs RAM
via Linda file manager and auto memory manager (which tweak's android's memory management, not a standard task killer), i saw many apps that always run (many with priority equals to android system and the phone app) such as "wifi calling, visual voice mail, my account, qik, device management, drm, etc.
not everyone use these apps and they take up precious RAM and tiny amount of CPU cycles.
worse, however, is how the phone keeps loading unused, unaccessed, unwanted apps into memory (been weeks since I used pandora, yet it keeps getting reloaded into memory).
from clean boot, I get 150mb free. after a week, I get 45-55mb. This causes memory manager to kill off app as soon as you switch away and alot of stutter (dont you hate it when your browser gets killed)
Dont know if theres a fix for this. I tried tweaking the OOM parameters but it doesnt seem to work on this phone. Samsung probably tweaked something that broke this.
i dont really know too much about AOSP rom's but from what i hear they are very basic.. what makes that so great? i really have no idea since ive never used a AOSP rom. just wanted to know cuz i always hear ppl talking about how great they are. thanks
They are true Android. Built clean from source code from the AOSP website and modified to work with the specific phone. Basically its how every Android phone should come but each manufacturer likes to mess with the software and add their own stuff.
i agree, AOSP is very minimalistic, thats why i prefer them over an other rom
They're fast. Pretty much the main reason anyone switches.
Like the unlock screens this phone came with, both of them sucked. The puzzle was annoying because I would miss the swipe about 15% of the time while the glass unlock screen was just bad looking. I don't see the big deal about AOSP seeing as i replace pretty much anything AOSP/stock anyway(messenger, lockscreen, browser etc). I get it's there for the simplicity and stability but it's just boring if you ask me.

AOSP is pure google experience. AOSP ROM's are google experience with developer tweaks.
It doesn't require many approval processes, so it runs the latest version of the O/S usually before phone manufacturers can get them out
It is very slim and minimalistic with it being highly customizable.
It comes minus any bloat, all source code is available, full wiki with instructions to remove any portion you want, teh ability to grab the source code and compile it yourself..etc.
Here is an example as far as bloat goes, I had the thunderbolt for a bit, CM7 checked in around 80ish mb. A sense rom was going around 400 mbish.
I'm assuming then that the RAM usage by the OS will decrease dramatically from what it is now?
Its crazy to me that this device sets aside almost 200mb for the OS anyway, yet on startup, another 200 is used up immediately (I rebooted and cleared memory just to see).
Just seems like a rather large footprint.

Android isn't like your pc operating system. Unused ram is wasted ram. Apps are loaded in the background so they open quicker when you use them. When the ram is too low it kills off some processes.

Yea, I saw that response coming. I get how it works.
However, if you had more RAM to start with, more applications could be cached at a time which means your device will be opening more apps quickly. That's why I rebooted my phone before I provided numbers, because I'm asking about the RAM that the OS leaves free to actually do the caching.
Are you really trying to tell me that Android is so good that it wouldn't benefit from having more RAM available to it on startup?

No I get what you mean. This phone certainly does suffer from a lack of ram and aosp will help with that.
However, rebooting doesn't really tell you much about ram used by the os because it begins caching apps before it fully boots if I remember correctly.

Lol, the more free RAM, the more efficient and faster your phone runs: for example, my old G1 with its limited RAM would freeze for 3 minutes if you tried its phone dial app, mind you it would happen almost randomly as the phone swapped out memory, oc'ing the g1 CPU made no difference since the bottleneck was the memory size. So, the more ram you have the better off you are.

Typically the AOSP roms will be packaged together with a custom kernel built on mtd/yaffs which I believe to be the largest performance enhancer. The fact that the AOSP rom is minimal and has all the benefits as Utnapishtia mentioned just makes it that much faster because it's not burdened down with unnecessary garbage.
I'm curious about how much free ram everyone has on average after their rom has finished booting and stabilized! Post it here!!!

how about a screenshot? that's pretty good!
Here it is. It bumped down to 237mb by the time I thought to screenshot it.
i run about 40-80mb free on average just the way i want it.
Android uses ram differently than other operating systems like windows or linux,
it fills your ram with things that you have run already in hopes that youll run them again and it will be alot faster the second time. if it needs that ram for something else, it just kills a program and removes it from ram (this takes VERY little time)
so the more ram used the better

thats about all it holds. the VM heap settings are what causes this (in part) each app gets its own virtual machine to run in, this has a limited heap (ram) size of whatever is set in there.
so if your VM heap size is set to 48mb... 48 * 5 = 240mb and 48 * 8 = 384mb
add in whats needed for Android system, kernel, and various background processes that you need... its all gone

so u dont agree with auto task killers and you saying the system runs better with lower ram?
that's what he is saying, that's been known since eclair was introduced to android though... I just never thought of the more ram being used the better.

that's what I'm sayin! if the OS already has the program your trying to launch in memory, it wont need to load it, saving time and power.
and if you kill programs forcefully, android (kinda) treats it like it crashed, and reloads it into memory soon after...

ok so memory can go below 100mb without a problem because i always try to free memory around 150mb

it all depends on what your min-free settings are.
the apps that fall into each category are slightly different for each ROM, but whatever the highest setting is at is what your free memory should sit around, and it can and will fluctuate alot for seemingly no reason.
and before you all go out and change them as high as you can, just know that free memory is wasted memory, it takes NO power to keep things in memory, but it does take power to put things in memory every time you open it!
This explains it a bit better than i can.

makes sense, so basically task killers do the complete opposite? lol i will let services and apps stay in memory without a task killer and see how things go
I updated my atrix 2 with official ICS update 672.1.18.MB865.AsiaRetail.en.03 but found it to eat up all my RAM, normally i always had atleast 450-500mb free in normal state with the backgroud processes on, but after loading ICS i found my free RAM to be only 190mb-230mb. Does anyone face similar problem or know how how to rectify it???? I even uninstalled some of the Apps which work in background to get some of RAM back so i can play graphics heavy games, but it didn't help. Senior members please guide

GB software was/is very stable and has great performance, so it’s not a bad idea for some to stay on this release until the official OTA has been pushed and tested by the devs to check the possibilities for flashing back to GB - if at all. ICS is more intensive, for example, in terms of resource usage. As smartphones become more capable, our own applications, as well as the Google Mobile Services (GMS) applications, are becoming more advanced, which means that they require more CPU power, run more network activities and use more RAM, and full hardware acceleration also results in a need to load additional graphic libraries for certain apps, which makes them use even more RAM.
Another effect of the hardware acceleration is that it can make the battery drain faster in some cases. An example of this is video playback, where the hardware acceleration requires every video frame to be run through the GPU, thus making the system use more power than it would have without HW acceleration.
Out of your RAM, about a third is used for functions that require a dedicated memory allotment to operate fast enough. For example, this is the case for certain multimedia functions. The remaining space, is reserved for the Android OS. Within the Android OS, functions like the activity manager and Home screen app are running.
When running low on RAM, typically with less than approximately 40MB left, the activity manager will start to close processes according to priority. At first, idle background activities are killed. The last thing to be closed down is the foreground activity.
Processes that are closed will obviously have to be restarted when the user enters the app again, which takes time and slows the system down. For example, when running a heavy game that uses all available RAM, the activity manager will be forced to kill all processes running in the background. This might include vital functions like the dialler and even the Home screen application. When you exit your game, there is a risk that the phone is perceived as slow, since the Home screen app will have to be restarted, just like every other activity you access afterwards.
Another interesting thing is that many apps use slightly more RAM in ICS. For example, the web browser is quite intensive, and uses 20-30MB more in ICS compared to GB. All in all, there are a lot of changes that together result in greater RAM requirements, and resource usage in ICS is heavier on the system compared to GB.
I've found that Android runs fine without having much free ram, if you think about it logically there is no need for free ram, if every bit of your ram is going to something then everything is going to work fine. My G2 has 366mb ram, about 40 of that is free right now, but the system still runs smoothly (mostly due to my 1.3ghz overclock), and I can multitask and play games just fine, Android manages memory very well. Keeping an eye on free ram isn't important, you should be worried if things start closing and the OS starts running very slowly tho. Is there more free ram with some of the mods in the development section? SCV7 and stuff?
To make it long story short,it being official firmware will have loads of bloatware and moto stuff that people hardly use.May be that is what is consuming your RAM.Just what I think.You can root and use Titanium backup to freeze/remove that bloatware

Good point, the bloatware and blurware definitely bogs down the phone, happens on pretty much all phones with manufacturer skins. Which is why CM and AOSP is so awesome.
How does Jb compare to the memory useage of ics? Will it be better?

I wouldn't hold your breath for JB on this device. I mean, for gripe's sake, look how long it's taking to get ICS for the A2. But, aside from this phone, CM10 on my S3 is flawless, I have absolutely no complaints. This phone, and this ROM, are perfection...

i asked about gingerbread sir......comparison of battery life
For me i guess battery is draining just a little lesser in ICS than GB. Difference is not very huge but there its a slight improvement...also you can disable few background tasks...

i have a similar problem but ...
i recently just flashed the ICS Supercharged rom and each time i boot up there is a notification that says " Low on Space". well i read around forums and they were talking about not having enough RAM, i am also running ICS leak and i am using bootmenu to keep both kinda like a Virtual Box. Could i solve this problem ?

surprisingly this OTA release is clean and neat with less such stock apps.. and if you want there is an option in the manage application (Settings -> Apps -> ALL) to "Disable" any such stock aps. I've disabled a few annoying running service for me, News and Weather, Facebook, Face Unlock, Social Location, Task etc..

I believe you have to format the webtop partition if you're using it for the 2nd system. I did that and had plenty of free space.

Battery life on ics is actually pretty good.. Running on sc7 leak 2 and my bat life for some reason has greatly improved compared to when I was on GB
would that mess up with my webtop

And The task manager which we had in gb is gone. That could do auto kills which was great.

I can't seem to find a definitive answer anywhere as to why our 1 GB RAM only shows up at 669 MB on CM10.1 nightlies. I can understand the ROM requiring some space, but 355 MB seems excessive.
So what's the real deal behind this? Other 1 GB phones seem to still show up with 900+ MB in "About Phone" - eg the One X, also using CM10.1.
The reason I am keen to know is because using the default minfree values (I don't really want to have to tweak these), I find apps close WAY too often when something runs in the foreground. I have trimmed down my memory footprint majorly, have only a couple of essential widgets and three home screens. I don't think that in 2013 with a phone that has 1 GB of RAM one should need to minimise things down to one home screen and one widget just to be able to run memory-hungry apps.
So does anyone know why CM10.1 eats all the RAM, how to get it back, or how to stop apps from dying all the time? I can't even get through a 3DMark or Basemark X benchmark without it crashing halfway through due to lack of memory, even with all background apps closed.
Any insight would be much appreciated.
same issues
I have a sgs1 (i9000) and am having exactly the same issue.
CM10 was fine..I always run the screen filter app as I find even the dimmest of brightness too much. It NEVER would close this app before, since CM10.1 on using any app it does it all the time!
What is so f******* frustrating is that i am very ill in bed & with photosensitivity..so going from a screen dim of 38% to whatever the default auto is (really, any of these stock settings are bad for ur eyes long term!) just makes me scream!!!
I have 386mb or so, so obviously this is not the fault of my phone since u r having the same issue with much more memory than me it's something they have changed in CM10.1 since screen filter is a tiny app.
I frequently close all apps with a task manager & anyone that thinks they r a smart a** telling me 'android has its own memory management..u don't need to do that..it will make ur phone slower blah blah crap is talking up their exit hole lol I have disabled most apps running on various state changes via autostarts & my phone works faster for it! Some games WON'T load unless I close apps or restart - I'd like to see ur excuses for this lol There is a difference with the technical & the reality in this sense believe me!
I am considering going back to CM10 as this issue not to be sorted by now is ridiculous, but perhaps only a few have it as I don't see any replies to ur question.
I also thought about this... Where is the RAM? I tried CM10 and back to stock for 1 Day after flashing... I am more satisfied with my cleaned stock..

If I remember right some kind of cache is on ram but even sense don't have 1gb yet One X does.

I feel you. I got the same problem with CM10.1. CM10.0 left me with a total of roughly 783MB. Apparently I was told it's something to do with the kernel and that the developers have not been able to work out the memory management.

669 here too

You'll never get the full 1gb, because the gpu etc need some shared ram too. But I want to know why cm10.0 has more memory available than cm10.1 on the same device
Well it seems the latest nightlies (unofficial) since yesterday seem to have resolved the memory issue.

Did someone confirm this?
Is there now something like ~800MB usable from within Android?

No the total usable is the same (669 MB) but there is much more of it free due to some memory leaks being fixed.
Thats nice to hear. Waiting to see if some bright mind fixes the low available memory issue on the One S. My other device the Xperia T has the same (Qualcomm snapdragon S4) chip set but much more usable memory in CM10.1(800MB)
Any news on this? I saw that the one s c2 has got 800+mb free on cm10.1: http://forum.xda-developers.com/showthread.php?t=2263235
