My RAM (not internal memory) usage is terrible. Out of 190MB I have 63MB free. Anyone have any ideas how I can improve it, or is this normal??
I am running CyanogenMOD 6.1 with Flykernel 12a (well check my SIG for info).
Any help would be GREATLY appreciated!!
That is normal. In fact, 63MB is quite a lot, usually it'll dip to between 35-40MB.
Why are you bothered by 63MB? After all, unused RAM is wasted RAM.

I was under the impression it was like a computer, the more ram available, the faster it was...
Is that a wrong assumption?
RAM is fast(er) than flash memory (Which may be used for swap etc).
So loading apps into RAM is beneficial.
While having more RAM is indeed good, having more free generally isn't.
RAM is there to be used. I run CM6.1 and it manages itself fine, so you need not worry
no probs, I'll stop fretting... My Internal storage sits at about 157MB
When I free my RAM I'm getting about ~70Mb maximum but normally 35-45Mb. Remenber that's not Desire HD that's an old phone.
Android's internal memory killer will keep everything OK... There's no need for more RAM to make it faster.
In fact, using taskillers to close apps in the background actually may slow the phone, as the apps have to "reload" fully again, rather than residing in RAM. If that space is needed, it will be freed immediately
So yeah, don't worry about RAM usage whatsoever
Hello, as we know, Galaxy S1 was advertised with 512MB ram, but in real there was only ~340MB of usable RAM! So i want to ask, how much ram is usable for applications and how much is free after fresh boot? Can someone check this? You can see this informations in task manager.
I think its about 800-850 RAM.
The original SGS had 512mb of ram as advertised. For some reason people assume that their phone behaves different than their computer. The operating system and everything like that needs to use the ram as well.
AS stated though I understand the SGS2 to have approximately 850MB of ram free after running the OS etc.
If I continually hit advanced task killer it will give me about 445MB free. In the standard task manager it says /833MB.
I don't really think this is all too relevant. You will never have anywhere near the maximum amount available just as you won't in a modern PC either and with phone OS's getting more power hungry and complex this is unlikely to change.
If the amount of ram bothers you check the video of the guy doing heavy multitasking on the phone and that will clear your mind.

Thank you for usefull information. I'm just interested in real numbers, because HTC phones have all advertised ram available to system, instead of samsung, which is cheating about this. Yes the OS is using ram... but from 833MB, not from 1gig. How can system use ram which is not visible to system? Android is linux, you can easily see how much ram is available and usable for system... it's 833 not 1gig. I believe that there is 1GB ram chip, but some memory is dedicated to other components. However 833 MB is really enough for mobile phone.

It did have 512MB of ram in hardware, but a pretty big part of the 512mb was actually dedicated video memory for 3d and movies. The Galaxy Tab 7" which was advertised with 512MB actually had ~600MB of ram in hardware, with extra ram outside the 512MB being for the dedicated video.
With the SGS2 it seems to be as the original SGS with dedicated video ram being taken out of the 1GB. It's easy enough to check by looking at the kernel config files. (And you can even tweak the numbers a bit to get a bit more free ram, as was done in the SGS)
Hope we're not heading down the old line of trying to run with loads of free RAM... I'm of the philosophy that if you have the RAM available, you should use it, rather than have to load things up from storage due to removing it to make a number bigger on a task manager...

Your philosophy is absolutely correct. In Windows that might be a good thing, because it starts buffering to the HD when you run out. But Android will just close some background processes automatically to clear ram as needed.

Unfortunately people these days only know about ram management from that poor excuse of an OS called Windows.... excluding 7.

Agreed, as long as there is a big line between FREE RAM and TOTAL RAM. More total RAM is always a very very good thing regardless of how good the ram management is.
This thread is about total RAM available to Linux/Android, so it's good imho.
I have been so busy catching up with all the amazing stuff Da_G has been pumping out (thanks!) that I didn't even take a look at this until now. I am showing that we only have 733MB of avaliable RAM. That is a far cry from 1024MB.
I am seeing 733MB w/ both Android System Info and with the built-in Task Manager.
Does anyone know if we indeed have 1024MB of RAM and... if it is just assigned else where?
Yes we have 1GB every phone has RAM missing because the system is holding it.
I remember one time the OS didn't support that much not sure if that's the case now but the phone has 1GB to my knowledge and.what I've read

I am with you on that! Makes me
I noticed the same, it's showing short but using the same app(system tuner pro) on my G2 it showed the correct 512mb.
It's not false marketing; it's fact. There is 1GB of RAM in the phone. I'm pretty sure the rest of the RAM is used by the GPU. My GS2 has the same thing, shows about 800MB of RAM available to apps.
What does it matter? I usually have 3-500MB of free RAM. Have you ever managed to fill the RAM with processes? Do you know anyone who has? Android clears old apps from memory even when there is enough free so I have never even come close to filling my RAM.
Graphics memory
As with any computer your phone has a gpu which needs graphics memory and because the gpu is integrated (SOC) it takes its memory off the top. This can be seen with any computer you have with integrated graphics it will section off some memory for your gpu.
As for the flash memory space many issues can take it down such as the file system, operating system, it just depends but trust me before the phone was turned on and android installed it had 16gb of memory and 1gb of ram
I'm about 100% CPU and GPU can't share ram as they do completely different tasks. They could have just added the cram and the ram to get 1GB though... But otherwise, the missing ram is from system tasks and the OS.

Do we have a reference or any proof of this?
And to the post directly above this, any computer that does not have a dedicated graphics card uses shared system memory, just like our phones. 733MB is just quite a bit away from 1024MB.
they can and do use the same memory because they are the same soc aka system on chip. all this is integrated.
So if you built a PC yourself and loaded it with 2gig RAM and booted into windows it would have 2 gig FREE memory?

I am not talking about FREE. I am talking about the system as a whole. Do we really have 1GB of RAM? Where it is being used I am not so concerned about at this point, but it may help us figure out if we do indeed have 1GB (Where is the remaing 291MB assigned).
The missing 291 is being used by android..to load the launcher Widgets and everything else in the background.

i have international version of note.its same way on this one.the missing ram is held by system tasks.as for 16gb storage memory.if you wipe all area on usb storage .u will have 16gb but not a working phone.another thing about free ram.dont use task manager to stop apps.all it does is make the phone lag.leave everything running.

Hi, i just wonder why this phone use ram so much high? (mine: usually at 1,7GB). At first time i use this phone it was used about 1.1GB of ram.
I'm trying to compare this phone usage with my previous tablet, samsung galaxy note 10.1 and it just consume about 700MB of 2GB ram it have and at first time i use it consume about only 500MB ram.
For your information, i use almost same app running in my booth device. But..
Why it come so much different? Z2 for sure have 3GB ram (bigger than other) but i think the system at least consume much more ram too than others. Are I'am right? Can u tell me what do you think? And tell us about your idle ram usage too if u can..

I think nothing of it
Linux is healthy to use ram unlike other OSs when ever you open an app your phone will free ram if needed, its not to hard seeing as how its managed
Your actual free ram is always 15mb but freeable is usualy always %90 of your total ram, ignore how much ram is avaliable
If you want to know more, look up linux ram management
Sent from my D6503 using XDA Premium 4 mobile app
Looking at RAM usage is entirely pointless.
Apps allocated RAM as they like but the operating system makes all kinds of predictions ahead of time to preallocate blocks of RAM to increase speed, eg when an app requests to allocate some memory the OS gets to instantly go "here you go; hehe sucker I already prepared that earlier".
The OS will more or less allocate as much RAM as you throw at it up to realistic limits. Eg once a tiny app has 1gb of ram the OS will take the educated guess that will be more than enough for it and not allocate any more.
If another app opens up and the OS is running low on memory it will rejig how much it has allocated to apps that never actually requested that much memory.
This happens on any modern OS and is why you should never really care how much RAM things are using.
In Windows under process manager if you looked you would find there is about 10 different ways to look at the RAM usage per app. Unless you really know what the numbers are saying they will all means basically zero in the real world.
Woa.. I never know it before.. Thanks for the info..

mine is usually about 1.5 to 1.9GB
keep in mind it caches apps too incase you reuse them, at the top right of the usage screen hit the menu to see the cached apps.
Mine is usually 1.5 to 1.7GB, even I don't run any app...
BTW, I install the app Clean Master ( like CC clean on Windows). And I always do clean Junk file and Boost ram once a day.
Is it good to use this app everyday?

If it's another generic 'ram booster', it's next to useless, but it won't be dangerous to use unless the app is programmed poorly. As others have pointed out, if there's no problem with the system (e.g. memory leaks), the RAM it allocates is used for caching apps so they may load quicker. Simply put, this behaviour is intended.
Cleaning junk files will probably have next to no effect on perceived performance as well untill you've hoarded enough junk files that your internal memory is almost full. But I see where you're coming from; it's very satisfying to see memory freed.
And while I am at it, I'd like to recommend SD Maid for this purpose. It's one of the few apps that actually do something useful. You can delete orphaned folders by apps that are no longer installed, delete junk and duplicate files, bulk clean app caches as well as optimise internal app databases.
How much difference in RAM usage between 720p & 1080p display? Z5c RAM way too low?
I've read several times, that a 720p display uses less RAM than a 1080p, plus the Z5c has a couple of extra features, like 500MB of ZRAM, which should make multitasking quite good and not a thing to worry about, despite the low RAM.
But here's the thing: Can anybody tell me, how much exactly is the difference in RAM usage between 720p and 1080p? I was never able to find hard numbers. Is it 50% because of half the resolution? Is it like 5% only or something else? Or is it flexible, depending on the apps? Or, if it's a fixed amount of megabytes, how much is it?
I'd love to get the Z5c due to the smaller size and it is about 100€ less than the Z5, but I'm also a heavy user and struggling very much with only 2GB of RAM in my current Z1.
I have at least 10 different apps running in the background all the time, like weather widget, several messengers, xposed, data counter, greenify, etc.
Plus, I usually like to open a lot of tabs in the browser, 10+ is quite often and my browser either craps out completely and closes itself or the tabs have to reload all the time, this even happens with only 2-3 tabs.
Same with apps.
They are almost always reloading, most of the time I can't even visit my "friends" in Simpsons Tapped out because the game crashes when I try to visit their cities or it crashes in my own town because it is too large.
The music player stops working during browsing or one of my running apps closes itself due to lack of RAM.
Is this normal, is the RAM really too low or am I just expecting too much from smartphones? I treat them like small computers, like the ads suggests. I guess, they are just too unrealistic.
The ONLY thing keeping me from going for the Z5c is the low RAM and this would be the only reason for the Z5.
Also, 2GB RAM is a 2012 standard, it's now 3 years old. After a usual usage time frame of the Z5c of 2 years, it's 5 years behind. I simply can't seem to get myself to buy an already outdated device in terms of RAM. For me, 4GB would be very welcomed.
Can anybody answer my questions regarding RAM usage or someone with a similar heavy use case can relate their experiences with the Z5c and RAM problems?
The RAM is more than sufficient. I have been using this phone for some time now and I can keep any number of apps open in the background and they do not close.
---------- Post added at 05:38 PM ---------- Previous post was at 05:37 PM ----------
When I say "any number" I mean any number of apps that I need to keep running in the background. I've never run out of RAM on this phone. Whereas I see a lot of phones struggling with multitasking
I don't just mean many many foreground apps which I have started myself and switching between them, but also like 10+ apps which are running as soon as the phone has finished booting and which I want to run in the background all the time, without counting additional apps which I open on purpose. Apps always running are: Hangouts, facebook messenger, Whatsapp, weather widget, one handed mode, 3G Watchdog, onavo extend, proximity screen off, greenify, setcpu, automate it, afwall+, twilight. A total of 13 background apps plus many foreground apps. After everything has loaded after boot, I'm already down to 700MB free RAM, without any other open apps.
When RAM reaches 500 or below, the force closure starts.
How much is your available RAM after boot and with many apps running?
i don't know if you are aware of it, but xposed module "app settings" has an option to keep chosen apps persistent in memory. I cannot assure it works, but probably it does. You could enable it on the apps you need to be kept open and then fill your memory fully, then see if Android system kills other apps (camera, gallery,...) instead of your favourite ones. This might be a workaround for you, or might not: if you open lots of tabs on your browser, Android kills other apps, while Windows would become sluggish but keep everything open and use the swap file. Regarding the swap theme, Android has the Zram function, a kind of swap file in the ram, that compresses some RAM in the RAM itself (at the cost of some CPU power). This might also be useful but don't know if it is already supported by stock xperia firmware or it must be implemented in a custom kernel.
Well, available RAM really doesn't matter much. Lollipop especially is designed to take up as much RAM as possible. That makes the operations smooth and the processes run in the background. But I'll attach this here. I never clear the tasks and I always keep them running so I will have less RAM. But my apps don't close on me though
It seems 2GB ram doing fine on my Z5c, I guess because of it comes with ZRAM enabled in stock kernel(for the cost of cpu and battery). Yes, 720P spend much smaller amount of memory and cpu compared to FHD/2K. There are many reports confirmed on Z1/Z2/Z3/S6 board when people used resolution changer and found much more free ram available, you can try QHD 960x540 if you want even more free ram.
I got 1GB free ram after boot up and same with my S6 but since my S6 running 2K resolution with poor Samsung memory management, actually the Z5c performs better when deal with the killing apps problem. If you will use greenify donate ver to freeze all bloatware I think memory is good, the android 6.0 seems to have better memory and battery life as well.
Can you tell me more about the resolution changer? Is it dangerous and can lead to a bootloop or not booting at all?
Z have 2gb of ram and 1080p display and have no ram issue..

I don't use it on my S6. It won't bootloop or not booting but just some stock apps will have menu problem bcoz they are hard coded for native resolution, you may need to decompile those apks and edit some .xml files manually to modify the default resolution to make it works.
even my XZU with 2GB of RAM and 1080FHD is still perfectly able to multitask. no need to panic for such 2GB of RAM. yet. :fingers-crossed: well maybe when there's a game with big memory requirement in 2-3years time then you'll need more than 2GB but i bet it's not a game worth playing coz it's not mobile optimized and the devs are too lazy to optimize.
Default set at 507MB ZRAM, you can increase it to 1024MB if you wish
Yes, but only with root? And then you lose the warranty, camera functions, miracast and such because you need to unlock the bootloader.
A root exploit without bl unlock, like on my Z1, is what I'm hoping for. I also don't understand why manufacturers don't implement to gain root access via a simple reboot. Make the option available, display maybe 2-3 warnings and info screens before, then if you click yes, a reboot happens and you're rooted. Easy as this. No features lost, no exploits necessary which take forever to arrive, if at all, and involve downgrading and such. I think one manufacturer enables exactly this.
It would be unthinkable on a Windows or Linux system if there wouldn't be the option to work with full admin rights...so why is it the norm on Android and nobody bats an eye?!
Btw: I've tried the resolution changer and changed the resolution to 720p. Although this should have decreased the RAM usage, it actually increased it by around 100MB. How is that even possible?

I think you answered your own question here. If you need a whole lot of RAM, you should probably look somewhere else.
yes, it needs root and you loss warranty and DRM and such stuffs.
Linux like to cache things, if u got more free ram it might just cached even more. It won't used more 100MB ram in reality.
The thing here is the Android 64-bits.
1080p device with 2GB RAM in Lollipop 32 bit = more than 1000MB of free RAM (average).
720p device with 2GB RAM (and zRAM) in Lollipop 64 bit = more than 550MB of free RAM (average).
Now, the resolution mostly affect the used RAM when gaming, there is not a big difference outside games.

I have never seen free memory more than 1GB of RAM with my XZU. Right now it hovers around 600MB of RAM.
for gaming it is not an 'always' case so memory cleaning at the end should happened only 1% of the time you use the phone.
Who cares about how much free ram there is? The ram is meant to be used and Android is made to use the RAM for caching and so on.
Talk instead about how well it runs in practice.
Anyone that has experienced any problems that could be because of the device only having 2GB of ram? Let us know.
If not, then I guess the fact that the Z5C "only" have 2GB ram is not a problem...(?)
Here,me! I'm having a lot of problems because of low RAM and the whole purpose of this thread is to find out if the Z5c with its 720p display and zram and such makes a huge difference in RAM performance, if at all compared to my Z1 with also 2GB which is always reloading tabs, crashing games and apps, force closing apps due to lack of RAM, redrawing the home screen when exiting apps and so on.
If there's no big difference, then devices with only 2GB are not for me.
It's good that Android uses all the RAM for caching, but I strongly believe that in my case there is simply not enough RAM and that's why all my problems occur.
And also Z5c uses LPDDR4 RAM if I am not mistaken. So that's actually more efficient. Well I have faced ZERO problems with multitasking. But I dunno about you
