Ok I've had my phone for two days now and I have been checking the RAM usage on the phone. With 0 applications open my usage is between 1.12 and 1.25 GB out of 1.78GB total. When I have a few apps open it can easily go up to 1.55GB. Is this normal for the galaxy S4?
Heres my usage as of right now

Is this phone stock? I'm worried theres something wrong with my RAM.
I'm getting the same high memory usage on rooted/debloated stock. It doesn't seem to have an ill effect on the device. It still runs very smooth.
There can be two reasons
1. Memory Leak
2. Proper utilization of the free space in RAM
If the phone is running properly without any stability problems then, Memory Leak is hardly the reason.
This brings to the next reason. We have 2gig RAM in S4. If it had to use only 500 MB or so, then the rest of 1.5 gig wud be for nothing. One shud be happy that the free space is being used for some performance rather than staying useless.
Moreover Samsung clearly mentions that the even applications are not running they are loaded in RAM so that they can be opened quickly. So, I think we shud just trust Samsung or the developers on this.
And another thing, I dont think we shud be worrying about the RAM usage unless we have unstability problems. Let Android handle the RAM.
Chill n have fun with Samsung Galaxy S4...

Yep, stock rooted...actually running the developers base with faux kernel...so stock rooted, deodexed, zipaligned, with a custom kernel - not debloated in any way

I need to relax
Yea the phone has been running fine for the most part. I noticed some frame choppiness in Temple Run 2 that never occurred on my Note2. but other than that its been fine. I guess I just need to chill. Thanks for your help guys.
This is Android, not Windows.
Free RAM doesn't buy you anything in Android. In fact you want Android to use memory.
Don't worry about how much RAM is being used, concentrate on how responsive your device is.

Android is an entirely different beast than what most users are accustomed to...
Just curious, but is anyone else experiencing 1gig+ worth of ram usage with no apps running? Just seemed a bit excessive to me for the system to take up over half the total ram in the device.. thanks in advance.

What is your concern here? Do you run out of RAM when you start up all your favorite apps?
No, it's not an issue for it to use half the RAM for the system. Keep yourself from looking at it. It's fine.
People need to learn how android manages RAM, it uses parts for system and the rest is only freed from older running apps when needed, high ram usage is not a ISSUE! as a great dev on the xperia play section stated @CosmicDan "Free ram is wasted Ram"

I would think that if it works anything like a PC, then the more code you can get into RAM the faster it will execute as compared to having it pull/swap it from disk, or chip sets.

True, but if you're using a custom ROM it could be a memory leak. I recently learned that *many* builds of CM10 for many devices (mostly Mali GPU ones) have serious memory leaks with hardware acceleration.
You can free 120-200 MB by disabling LG MIT
Type 3845#*802# (if you have the international version) in order to access the hidden menu. Scroll down to LG MIT and disable it
search how android uses ram, and you notice, theoretically (pun intended), why low free ram is not an issue(supposedly)

Yeah well this is obvious, But usually this is not the case, And Hello CosmicDan!
it's always around 850 - 950 when nothing is open on rayglobe 3.2
just wanna say something to reach 10 post for development access !
Instead of checking for low RAM, check the Running Apps list and find the offending app/service that is eating RAM. Then see if you can disable or remove it. It could be a memory leak from a bloat ROM app or one you installed. Right now I have 100MB free on my 1GB phone but its perfectly normal, because there are so many apps in background that I use. In fresh boot its about 300MB free, because apps like Facebook and Tapatalk run a service all the time.

Guys my previous phone was s3 mini which had cm 11 installed. It used 400mb of ram and nexus 4 with same ROM 900. Can you explain that :0

If the system has more RAM will use more of it because it will make things faster.
Enviado desde mi Nexus 4 mediante Tapatalk
N4 uses on avg about 400mb
You have a lot of cached apps? Facebook alone can eat up to 100mb
And why do you even worry? N4 has 2gigs of RAM....
When you start out with around 1.8gb of RAM.
Have to deal with the fact that once you get below 500mb of free ram the device turns into a lag fest. Add in the 400mb or so that just running the system uses.
What's funny is the pr crap from Google. Oh we made kitkat to run on lower end devices. We used a crippled nexus 4 with 512 mb or ram. Well they failed. The OS still runs like a three legged dog when it's "low" on ram.
Interesting..
Any way to fix this?
I used greenify on s3 mini.
But I guess I won't be needing that since 2gb of RAM plus snapdragon s4 pro is just too high for phone to lag.
Nexus 4 is still high end phone, right?

Oh come on guys....it is 2GB of RAM and it is STOCK ANDROID! This is not Touchwiz for you to be scared of running out of memory.
I'm a power user and i have never had more than 1GB of RAM used..... just install greenify and enjoy life
Also, what lag? Only lag you will see is if you feck up your kernel settings, if you turn of 3 cores completely or underclock to 700mhz lol

Not really. Compared to this year's flagship devices, our nexus 4 cannot be considered as a high end device. Having said that, it still performs really well because of the stock android. Only drawbacks are its camera and battery though.

5 hours of SOT is good for a 2100mah battery....and regarding the phone status, it's still a High end device.
Just because it doesn't work at 2300mhz or that it doesn't have a 1080p display it doesn't mean it's not a high end device.
It performs as a high end device, which is what is important. What is the point of 2.3 Ghz when my N4 can run lag free underclocked at 1.1 Ghz?
It's all marketing

You won't run out of RAM because android went let it happen.
The system / apps uses more than 1gb all the time. There should not be a need for root and greenify etc
You can see lag everywhere. It's there no matter what the die hard android fans say. The launcher lags in the widget selection part. Google plus lags and so on
Its funny how people see what the want to see. Most of the same people are also the ones that move on to the nexus 5 and say wow this is fast, I though the 4 was fast etc. They then immediately see the difference. Something you never hear from anybody going from a iPhone 5 to 5s.
To other posters yes in theory free ram is wasted ram. But it's not wasted ram when you need to keep around 500mb free to keep your system running as it should.
Again. On ios you can run right to you run out of RAM and make the app crash. You won't notice it until happens. On Android... Oh crap. There goes the lag fast. Clear all greenify and so on. All while having more than 400mb of free available ram. Which is more than you would have on a system with only 512 mb.

Lol what are you talking about
I have no lag....not in G+, nor in Widget drawer.
iOS and Bada OS are similar. Bada 2.0 on my old Wave 3 was iPhone fast, and it only had 512 megs of RAM.
iOSBada & Android work differently.... what i've noticed that these closed source sh1ts have runtime similar to ART, hence they open up apps fast (even the Wave with 1.4 ghz single core & 512mb ram)

Whether it's better or not, I don't know because I don't use CM. Either way, it is good imo. You can try but not all phones are made the same. So, if it is good on mine doesn't mean it's good on yours too. You just need to try it yourself.
Note: If you are using CM, use the CM version.

That is why my friend, read what I said carefully. I did say it performs really well despite not having all those specs you said. 5 hours? Yeah, on wifi I can get up to 7 hours but on 3g connection, not even close to that. Best I can get so far with 3g all the time is 3 hours. That's my opinion anyway, why should we settle on good when it can be great. I hope the next nexus (if google still make it) would have a bigger battery. That's all.
What's the point of having 4GB of ram if the whole damn system takes about 3.5 gb living me with only 1.5gb useful. This is absurd! I will root and flash a custom rom just because of this. You know how SLOW our phones are running consuming more than half of ram??? Any way to fix this without root?

It's 3.5GB because the GPU needs 500MB allotted for itself.
What's the use of 4GBs of RAM if 1.5GB is not being used?
Android uses the RAM and kills things when it needs more. Idle RAM is useless RAM.
Plus 3.5 + 1.5 = 5.
Sent from my E6683 using Tapatalk
While this phone has a lot of ram and the management is much better compared to the s6 it's still not that great. The whole system does lag and feel bogged down. After clearing all the tasks it's smoother but apps will still close in memory and have to relaunch upon opening. I too am looking forward to rooting and custom Roms

What he^ said.
There could be 6GB of RAM and the system is going to use it. That's what it's there for. Android is built to effectively manage what is using RAM to keep everything running smoothly.

While I agree the RAM usage seems a bit high I haven't really seen any system slowdowns. I only clear out RAM these days out of habit rather than necessity and honestly I can't tell much of a difference in performance before and after cos it is a very fast phone.

For everyone arguing with OP; The problem seems to be that there isn't enough ram, and the system keeps shutting things down instead of letting them run in the background. Either that, or the ram is being managed poorly, and apps are being closed instead of running in the background.

Phone don't slow down. I wish there was more ram but I would of liked if Samsung copied apple in which you can go back to the previous app 10+ apps ago and it's still exactly were you where, with less than 1gb of ram? I don't see why Samsung can't do this apple gots a slight edge in multi tasking. But we have multi window. There "multi window" sucks soooooo bad. Only like 5 apps support that feature lol

Currently i am using ressurection remix which is pretty good but after closing a app the ram remain still occupied and doesn't become like it was before opening that app. please tell me which rom has best ram optimisaton
and for what you need free ram? If system or app needs more ram it will free it by himself, if you want install greenify and greenify apps, but for sure you don't need a lot of free ram.

I havent seen a rom with a really bad ram management here for our Bacon all the ROMs are based on one of the 2 'sources' we have. I wouldn't worry too much about it just enjoy the great roms
Verstuurd vanaf mijn A0001 met Tapatalk
If there's memory leak in the source, it will be there in all the derived ROMs. But you need not worry about it. Sources are quite stable and memory management must be equally good.
However, it can be a bit different on suppose an AOSP based ROM vs a LineageOS based ROM. This is also very kernel dependent. You should try them out yourself and see! Good luck.
