High RAM usage

Hi,
I noticed that ram usage on galaxy s4 is very high even when all of the apps are closed. I have used task manager to close all of the apps and then cleared the memory but there was still about 1.05GB of ram used. I don't know if this is normal since I haven't been using android phone for 2 years. Can somebody tell me if this is normal and why? If not what can I do to fix it? Thanks!

its normal for s4... some stock apps are being cached in memory for faster operations

unused ram is wasted ram. If an app needs extra space, something will be automatically killed to make that space.

all of this is true... also keep in mind, the gpu requires slightly more ram because of the 1080p resolution.

Ok. Thank you all for the help

This is the problem of Sammy ROMs, the only way to fix it is to... wait for a Custom ROM and Flash it

this is normal on SGS4 .
Reasons of that are mainly GPU and HQ resolution , cached services and process, and even more if you are using the included extra features (S-voice, NFC ...)
But the SGS4 come with 2 gb of RAM ! you still get like 800 free mb of memory that is good enough for all you needs ))
Personally when I close all apps i get 0.91 gb used memry and 0.9bg free memory

[Q] RAM manager

Hi,
I looked at my free ram and on daily use I have 1 GB of free ram.
So is there any sens to use ram manger to allow android use more ram (mean to not kill app and has less free ram)?

Unused RAM is wasted RAM (just before anyone else says it )
I have 1.3GB of RAM free on my N4. I wouldn't recommend a 3rd-party RAM manager, and just trust Android to handle it
Unrelated, but I have some weird memory leak issue on my N10 that basically causes all RAM to be taken up by something eventually, and all apps end up Restarting. Quite annoying, but the only thing I can do in this situation is reboot the tablet. Can't say I've seen or heard of this on the N4.

i cant say i like the way android does it, even though it does do it. i use greenify, and autostarts to prevent apps from starting in the background. also, i change the numbers to androids ram management. now im happy

But greenify make some apps start slower, yes? (because they have to start again)
How you change the number of free ram?

If you have widgets on your lock screen or on your home screen they will use up ram. Uninstall any apps you rarely use to free up ram.

Don't see why you're worried. You have as much FREE ram as an s3 does on the box
On a more serious note, I doubt you'll see any difference by freeing up ram. 500-600 mb of free ram = smooth experience generally

I'm no expert, but what I've read on these forums, it's best to just let Android take care of it. Android has come pretty far with memory management, and third-party apps might just end up taking more RAM/battery.

You're wasting your time worrying about it.

This is true, forget about ram manager and dont be paranoid about the free/used ram amout

Thanks for help, I will not use any ram manager etc.

[Q] What's your RAM usage?

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.

RAM Usage high

Hi,
I recently moved from Note 2 to S4. With my Note 2, I was able to freeze apps with TB to a low 390-450mb used. I was curious why the S4 uses almost 1gb most of the time and I was only able to knock it down to 800mb used with freezing some apps identified on other threads.
Thanks!

I am also curious about this and I also switched from note 2 to s4 but im just going to guess because all the extra features it has and upgrades anf even if some arent in use they are probably on standby still taking up some ram, idk thats just what I think?

There are more sensors on the S4 and thus more services required to run. If you missed freezing them they will eat RAM, and if you freeze some you will threaten stability. If you aren't sold on the stock ROM then try something from ASOP. Or some of the fully debloated TW ROMs like GOLDENEYE.

Why do you want free RAM?

You want Android to use RAM.

So high usage of RAM is good and won't slow down processors or heat up?
Thanks,

I don't know why you'd think it would heat up the processor, it won't.
While low ram isn't necessarily a bad thing with Android, linux based systems tend to use all the ram it can to speed things up,
With all of samsung's bloat it can slow things down if samsung bloat is taking up memory and you don't have enough for the active apps you actually using as the samsung bloat tends to stick around in ram even if your not using it.
Installing cleanrom (TW debloat) seems to have freed up some ram and things are running smoother than stock.

RAM does not heat up like a processor does, it will warm up because it has an electric current going through it, but it will not heat up more based on utilization.

Thanks for the info. Ill just leave it alone

RAM Consumption bit to high???

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.
Sent from my SM-G935T using Tapatalk

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
