Samsung Galaxy S5 Using 1 gb of RAM. No apps running. - General Questions and Answers

My Samsung Galaxy S5 is 1 week old, and it's using a lot of RAM. It has a total of 1.75 GB of RAM, and when I'm running no apps, it's using around 1.2 GB of RAM. Is this normal for Galaxy S5?

same problem to me
..

Same here not S5 thought
My galaxy note n7000 alway use 400-500 mb while it idle
(Seem normal for note) (Dirty unicorn rom)
Now i got galaxy mega 2 it's alway use 0.9-1 GB ram
No apps running
Why would samsung need that much ram for system?
Okay i found a reason
"RAM, either full or empty, consumes the same amount of electricity, unlike RAM in computers.
The CPU copies data from storage to RAM and then runs the app. If the app is already in RAM, the CPU won't reopen it, it'll directly use it.
So making the RAM full of opened apps helps the CPU. The phone becomes faster, and the need of electricity running through the CPU to open the app is now nonexistent."

Yeah, that's normal. TouchWiz is a very heavy ROM, with lots of extra features, which means lots of processes running in the background. S Voice, S View, S Finder, gesture controls, etc. And if you've purchased from a carrier on a subsidy or payment plan, that means you'll have some carrier bloat running too. Some only a handful of MB, some take more, but when you have so many running at once, it all adds up. On my Galaxy Light (a lower end device), 700-800MB of the 1GB RAM is typically taken up. On my Note 3, which I've barely done anything with yet, .9-1.5GB can be used up pretty easily without any multi-tasking. Obviously, the Note 3 has many more features, which needs more RAM. TouchWiz is very heavy, which is why most of their newer mid-end models have been coming with 1.5GB RAM instead of the "standard" 1GB - one gig just isn't enough to run TouchWiz, even though it's plenty for stock or near-stock phones like the Moto G.
What you need to understand though, is that even if 1.2GB RAM is used up, that leaves 500MB or so for all the apps you'll be wanting running in the background. Facebook, Words with Friends, the camera, music, etc. That's actually quite a lot. Also realize that "no apps running" does not mean that no apps are running. There are LOTS of apps running (every feature/function is an "app"), but they're not ones that you've loaded, but they're part of the "system", so they're already running and can't be killed. Facebook is one you've loaded. Smart Screen is not, but if you have it enabled, it's still running, and it's still taking up some RAM.
What you also need to understand is that you want these apps running in the background, taking up your RAM. And you don't want to be using a task killer like Clean Master to obsessively free up RAM pointlessly. When an app like Facebook is running in the background, it's quickly retrievable. Kill it, and next time you want to load it, it has to load from the internal storage into the RAM again, which takes time, processing power, and battery life. You can still use a task killer like Clean Master to free up some RAM if things get sluggish, but it's best to white-list the apps you use a lot so you're not constantly loading them from storage and killing your battery and wasting time. Or, if you were playing an intense game for a while, but don't plan to again for the rest of the day, by all means kill it with the task switcher. Android actually does a very good job of managing your RAM, and except in certain circumstances, it's best to just let it do what it does by itself.
If you can't help but obsess with free/used RAM, or you actually multi-task to the point of things getting frustratingly sluggish, turn off all the features you don't need or rarely/never use. Go into your app manager and disable (Turn Off) apps/features you don't use. Find a "de-bloat" guide for your phone and find out what's safe to delete or turn off. This includes Samsung crap, carrier crap, and even Google stuff as well. If you don't need Lookout, disable it. If you don't use Google Wallet, disable it. Samsung Print Service? You don't use that. Disable that crap. Some of these wouldn't be running in the background anyway, but it's easy to accidentally load them, in which case they'll needlessly be taking up RAM.

I cross-posted with your edit, but you've found some of the reason. As I said above, you want your apps running in the background, taking up RAM, unless you don't plan on using it again for a while. The other reason, as I said, is that heavy ROMs like TouchWiz, LG's Optimus UI, Sense, etc, have a lot of features and running processes compared to stock, near-stock, or the custom AOSP ROMs.

Question about RAM

I am running Froyo from Samsung web site.
Anyways, I know froyo was supposed to free up 512 ram. I know about 100 goes to gpu. However my phone is left with 339 ram to use (as seen in task manager). However it is always using at least 220mb, even when I close everything and restart the phone. When I open up advanced task killer it says 116m free. Why so little? How can I get more easily? without having to use ROMs or kernels?
Or is this how it is for everyone? I feel kind of cheated!
First of all, you should never need to use anything like Advanced Task Killer now that you have froyo. There are legitimate uses, but its really something you can go without. See http://www.reddit.com/r/Android/comments/cwovf/in_light_of_all_the_discussions_right_now_about/ for a good writeup.
Your phone, just like a computer, uses an optimal amount of RAM at all times. That does not mean minimal. Android phones dynamically allocate RAM for applications and the OS. Why have 200MB of RAM free when you can instead have 100MB free and have the phone be more responsive? 2.2+ manages memory more effectively, and if you are not using an application, will close it. Its fairly difficult with any normal usage scenario to cause your phone to run out of memory.
In short, you don't really need to worry about it because its that way on all Android devices (and generally any modern computing device), and that if is not affecting the usability then its not an issue
Completely agree With first comment. Everyone is concerned about keeping as much ram free as they can but it does not speed their phone up at all. Ram its just like quadrant scores a useless numbers if the phone is response and speedy in actual use

U could try reading this: Android Memory Management
your ram usage does seem a little high, you may have an app that is using a lot of it. the 339mb available is normal. some kernels will show quite a bit lower than that but the never seeing more than 116 free is odd. the rom im curently on fluctuates from about 140mb used to 240mb used. i only know that because i clear ram before running benchmarks, have you tried clearing ram in the built in taskmanager? or are you only going off the task killer? because the task killer doesnt necessarily clear ram.
all i know is task killers are pretty useless unless you have an app that freezes and for that the taskmanager built in to many of the samsung roms should be enough for that though it does not show every process that is in a saved state or system processes. task killer programs do more harm than good but i cant seem to get people off them. danm verizon store sets people up with them and poeple use them religiously. i figured out in the first few days of using android on my aria that getting better speed and battery life by killing tasts was a futile effort. there are few market apps that use resorces when running in the background and if you exit the app with the back button it doesnt save the state or run in the background. not that saved state is a problem. i only found that the phone uses more battery restarting processes that are designed to be running and has more lag than when you just use the phone and ignore the running processes.
Personally the only time you should be ever worried about ram is when watching a flash video or viewing a webpage with a lot of stuff. Other than that, as said, if the phone runs smooth, who cares about ram?

Available RAM Dilemma on the Droid Charge

I'm currently running EP1F Debloated with Gummy Charged
The phone typically says that, out of 312MB of accessible RAM, there is 60MB or less of free RAM.
i'm running GO Launcher EX, and on it's RAM meter, it's almost always in the Red (signifying that it's almost Maxed out in available RAM)
is this normal?
of course, any time i quit all open applications, the usuals always reload, but then sometimes odd programs will run in the background (i.e., netflix, google+, music, amazon appstore, picasa, ustream, etc). These are programs that I haven't even loaded or ran. they just like to load themselves up and run in the background. so because of this, my available Free RAM tends to sit at 39-55MB. that seems VERY low to me. and may be the reason why my phone tneds to bog down a bit and lag every now and then, when i'm going from app to app.
I know EP1F doesn't have voodoo lagfix yet (like it did on EE4), but this unusually high consumption of RAM seems odd to me.
does anyone have any input on this?
appreciate it
If you havent ran, and don't run those programs just get rid of them
no no no... I definitely run them. but it's probably a few times a day, sporadically.
but i don't need them to be running in the background, hogging RAM. whereas, i'm totally fine with an app like Gmail to always be running, since i check that all the time.
I use Autokiller Memory Optimizer, set to "optimal" preset. It's not a task killer, it just changes Androids settings to close programs at different trigger points. Keep some free ram and keeps the system from bogging down.
I also use Autostarts, which disables programs from starting up at startup or for other notifications that are set. Some programs still start themselves but it helps.
Why do you want free RAM? Unused RAM is doing nothing for you, Used is holding a program ready to launch so it's faster and needs less CPU to launch. Ideal RAM usage is 100% because the system will automatically make room for a new program to run.
Have you ever gotten a message that an app can't launch due to low RAM? Using RAM doesn't mean using CPU or battery. It just means ready to run faster.

Is the memory usage always so high?

Hey guys i have been enjoying my rooted sensation with ARHD 6.6.4 rom and its working perfect but i only have one issue.
Is the memory usage always so high?
I used this app called Memory Booster Lite and it shows used memory 75% and free only 23 or 25% always no matter how many apps or services i close.
Is this normal and is there any way to improve free ram memory?.
Thanks
Anything above 150 MB free memory is considered good in my books.
Most custom ROMs will get you between 200-250 MB free memory, which is normal.
You don't need to improve the amount of Free RAM you have at any given time. And your memory booster app is probably counter productive to achiving improved performance.
When you load an Android App, it will stay in RAM until something else needs that memory. It's not supposed to get dumped out of RAM just because you close the app.
If you have 100mb of RAM (using easy to work with numbers here) and an app takes 50 MB of RAM and anothe rapp takes 25MB of RAM, both apps will stay loaded in RAM so make them load quicker if you go to use them again. This saves load time and battery as the phone doesn't have to spend energy to transfer the app from storage back into RAM.
So in this scenario you'll have 25MB of RAM left.
Now say you want to load a 3rd app that takes 50MB of RAM. Obviously you don't have enough RAM to load it, so the system will now dump the other 50MB RAM user so it has room to load the new 50MB into RAM.
The system does it all for you natively so you don't need memory improvement apps. All they do it use up RAM permently (since they keep themselves in active memory and won't let themselves be killed) and use up extra battery power because they perform a task that will be performed again by the system later.
Android is very efficient at dumping apps form RAM when not in active use.
Over the course of a battery cycle you'll find that you use the same apps multiple times in a row. The phone app, text app, web browser app, etc are all things that you will use over and over and over. So rather than dumping these out of memory it keeps them so they load faster the next time. And it works VERY well. And it custom tailors itself to the user. If you never use the text app, but use Angry Birds all the time, Angry Birds will stick in RAM.
Sense is a RAM hog. If you want more RAM use AOSP. Having said that, free RAM is wasted RAM.

All of this. Every bit of it. I had to explain this to someone the other day who was hellbent on achieving MAXIMUM FREE RAM.

Wow thanks a lot for the explanation i really didnt know that.I got used to the pc ram optimizing hahahaha my bad.
so these apps android booster and memory booster shall i remove them all?
but apps running in background they dont drain ur battery?.
Like i am running music player and later i stopped it but its still there in process does it drain battery as long as its there in services?
High Always
Memory free has always been low to about 215 MB max. If you really want you can freeze sense and use a basic launcher from the play store to increase memory by about 50-70 MB.
Memory free is about 300 MB with Virtuous Inquesition 4.0.2 for me!

Yeah get rid of all that stuff.
And no, having an app loaded in RAM doesn't mean it's using processor power, which is what uses the battery. (Nor does it mean it's forcing the screen to stay on, which is your biggest battery drain)
Think of an app you just closed as a guy on a bus. He's just sitting there taking up a seat on the bus not bothering anyone. He doesn't weigh much compared to the bus itself so he's not decreasing the fuel efficiency of the bus. And when a little old lady needs to get on and have a seat, he'll gladly give up his seat for her and get off the bus....then patiently wait on the sidewalk for the next bus.
But as long as he's sitting on the bus quietly he's primed and ready to jump into the drivers seat if you need him to do so. Once he gets off the bus, it takes a second for him to reboard so he can drive.
well, all of this is so wrong... (this maybe true if gingerbread, but not ICS)

http://source.android.com/compatibility/4.0/android-4.0-cdd.pdf
ICS is designed for 1GB RAM devices (eg: Galaxy Nexus),
and ICS need at least 340MB for linux user space + hardware functions (eg: camera, modem) + 64-128mb max for each running application
so ICS will need more ram than GB. that's why I think 100-150mb free ram isn't enough on Sensation-ICS, especially if you run heavy games that consume very big memory

Maybe you forgot nexus s or some phone with 512MB, i use it on ics and still smooth and no problem with gaming.
Google never explain how much ram requirements to run ics they just said about STORAGE minimum is 1GB.
One of the improvement of ics is on memory management, we can call it ram management.
In eclair you have to use ram management apps to kill your background tasks in order to run heavy apps smoothly, but in gb google made some improvement on ram management so we dont need an app anymore.
In ics google improve memory management again, thats why even you playing heavy games then minimize it and open browser or something else, you dont feel laggy browsing or because system will kill the game, and you have to start from scratch if you open the game again.
And 768MB is enough for me to run shadow gun, x-plane, gta 3.
Do some research before you say something mate.
And for free ram, i can get 300MB on MIUI sense based, but i dont even care, just leave it let system do the job.
C'mon, we dont need 300MB (except for show off ) what we need is smoothness and battery efficient.

I thought that they did have rom management in older android versions. If all recent apps stayed open then it would crash the phone because it couldnt handle the load. And apps have different API levels which decided what apps were killed, depending on the kind of app(which you could change with an app). Ics and jb just have a better from management system. Correct me if I'm wrong
And could I hear more about the extra RAM?

yes of course you can run on sensation, but the system must kill other app running on background (just like my old moto milestone with 256mb ram kill app very frequently including homescreen launcher and it's very slow to start an app).

sure, nexus s meet the android 4.0 ccd because it has more than 340 MB RAM, but it struggle just like 512 MB sony devices
128MB is a MUST for each app, but have to adjust more if needed. So next year or two, all phone manufactures will not ship devices with 512MB anymore coz it's too slow & will kill app on background frequently (just like my old milestone)
if you're not developer you won't encounter about memory hungry app, currently I make 3D games on android and <512MB devices (such as xperia mini ics) will automatically exit, because my game take to much ram and probably draw calls (but run very well on my pc), optimization is the only solution (reducing vertices/poly & texture size)

haha.. you want more free memory? stop using a SenseUI rom...
trust me, youll get used to it. sense is nothing special after you get the full affect of an AOSP base
ALSO, just because memory is not free doesnt mean the memory isnt being allocated correctly. androids memory management is very intelligent. usually you dont need any task killers

Maybe 2 years later google will optimize more this beautiful os so it wont become recource hungry OS, do we really need smartphone with 4gb ram? So it will become so smooth.
Ive tried samsung GS advance and its smooth, maybe samsung do better job in term of software. but oh, i forgot GS advance still on GB

[Q] RAM ISSUES with samsung galaxy tab 2 7.0 (GT-P3100)

I own a samsung galaxy tab 2(GT p3100), which initially had 4.0.4 ICS with 687 MB RAM(but specified as 1 GB RAM, as some developers claim that it is being reserved for system). I updated my firmware to 4.1.2 and now it showed me 770 MB RAM. later i rooted my device and installed the latest CM(cyanogenmod) 10.1 (jelly bean 4.2). To my surprise this rom which has less bloatware and is smoother, it showed me 691 MB RAM, less than 770 MB as displayed by the STOCK jelly bean OS.
i would like to ask, which OS(custom/stock) displays the MAX RAM for GALAXY TAB 2 7.0(P3100)???????
as i don't ve enough internet downloading capacity(limited downloads), i can't just go on downloading all the firmwares and keep flashing everytime, SO EXPERIENCED USERS, PLEASE SUGGEST.
for more info(for my knowledge), do please tell this also--------->tab 2(my device specifies 1 GB RAM and the same does galaxy s2, but why with ICS(4.0.4) installed both the devices show different MB RAM. tab2 shows around 680 MB wheras S2 shows around 880 MB, wheras HTC one X shows 1 GB.
why is this so????? i know some developers claim that this RAM is being consumed by system or reserved for system, but why is it different for different devices, when the OS is the same?????
again if you claim that it is reserved by the android system, then WHY DO , WITH NO APPS INSTALLED TOO, I SEE AROUND 300-400 MB RAM BEING USED(300 MB WHEN I DNT USE ANY WIDGETS AND ALL, AND I STOP ALL THE PROCESSES, BY CLICKING FORCE STOP ON ALL APPS LIKE GMAIL AND EVERYTHING EXCEPT ANDROID SYSTEM AND PHONE AND SOME NECESSARY RED MARKED APPS IN THE DEFAULT TASK MANAGER).
if android process is being displayed here with this 770 MB ram, then where has the 230 MB ram gone------------>do you mean the android process consumes the hidden RAM and also a part of this RAM too???????------------------>this sounds too unpleasant, when htc one x displays all the specified RAM but my tab fails.
really disapponting
You are getting too excited about available RAM. The OS system manages available RAM so each different ROM will use it a little more or less.
The amount of free RAM has nothing to do with how many apps are stored, ONly how many apps are RUNNING. Android system efficiently manages RAM and tries to keep it about 80% full all the time. So called Bloatware (one mans bloat is another mans useful app) has nothing to do with speed , they do nothing if you don't run them.
The system RAM usage contained OS buffers, temp storage and system routines that are always loaded for speed.
1GB is a ton of RAM for android.
You do not have a RAM issue.
You can run out of SD storage space for downloaded apps if you store too many. But you have several GBs of storage so that's hard unless you are a real pack rat.

Right Sir,
well, regarding storage i dont ve any issue as some data like pics and vids can be kept in ext storage card too,but i also wanted to know which ROM provides user with more RAM, so that it will be good for multitasking or if i play high end games like NFS MW

The amount of difference between one kernel and another (which is what really matters here) isn't large enough to make any real difference in the performance of any application. The available RAM after the kernel grabs its stuff varies around 10% from one kernel to the next.
If you want to make a performance impact, make sure you minimize the number of running applications that compete for the available RAM. However, that won't make much difference as Android is very aggressive about grabbing memory back from idle applications.
Basically, you're obsessing over something that in the end will make no difference in how your tablet runs.

Irrelevant. Android will clear apps from RAM if it's needed by an app with high memory usage. This isn't windows

well, if this is the thing, and android can kill apps automatically then why do some people prefer custom ROMs like CM or AOKP.
even for installing custom ROMs they need to root their tab/phone, and if they root and want to get rid of so called bloatwares and make their OS lightweight, they can uninstall it using root uninstaller(available for free in google play)....
but why do they prefer custom ROMS?????

More features generally. Some roms will manage the memory better than others, ie at what point it starts to kill apps to free RAM(although this can be adjusted in any rom using rom toolbox or a similar app). many custom roms include a theme engine allowing more customiza. They may make better use of resources to decrease battery usage or because it has better cpu governors which will increase performance. They may flash a custom roms because it's kernel includes modules that aren't in the stock Kernel. There are many reasons besides RAM usage, since as you say you can root and remove bloatware and change memory handling(called minfree or oomut of memory)

Memory usage - huge amount unaccounted for

I've noticed my home screen redrawing a lot lately, as well as other apps launching fresh each time I re-enter them (feedly in particular, since it has a splash screen). Looking at the memory usage, the little curly brace shows the running tasks taking a small amount of the blue bar, and the cached tasks taking about half of the gray bar (in the "free" memory region).
I got my nexus 5 connected to the Android Device Manager to take a look from a different perspective, and the memory usage screen shows 1.3gb being consumed by "Unknown". I assume this is the sum of all the processes running, as it matches up with the running process bar on the phone.
How can I figure out what is eating my available memory, that's not listed in the Running processes, and not in the background?
Ram is supposed to be used on android. Free ram is wasted ram.
So, if your lagging, it's probably another issue. An app running that's lagging you out or something.
When in doubt, try clearing cache and dalvik in recovery. That usually can help.
Worst case....reflash Rom/firmware and start fresh. ?
This ain't Windows bro. The only time I worry about RAM on Android is when I try to run a 4.0 or 4.1 ROM on the OG Droid with 256 MB of RAM. Kitkat doesn't even begin to tax our device in the RAM department. If your phone is lagging, it is something with your config.
First off you have the FB apps and those are just badly programmed apps. When I say bad, I swear I get half the battery life when it is installed and it doesn't show up in the battery stats.

Also, RAM is used to cache stuff so it doesn't have to go to the storage. It is because apps can load faster when they are preloaded in RAM versus having to read from "disk". That is why apps use that space up. I have seen even comparing my OG Droid with the N5 in the same apps the RAM usage is way different because it has the space to use.
Why buy a Bugatti Veyron if you aren't gonna throttle it? Similarly if you have one of the top phones (granted it is a year old now almost, but the specs are still pretty high end) why not use the horsepower it has?

you need to download a task manager to see what app is using alot of ram, in settings/Apps its always around 700mb used for me but thats excluding cached,inactive etc. its really 400mb free.if you got apps redrawing when multitasking you need to check running apps and freeze some that you have installed, i dont know what apps you have.
