Thanx can you elaborate? trying to learn
2gigs on dual core would fly, but 2gigs on quad core would fly much much faster...

RAM isn't overly important in terms of speed. CPU is extremely important. Basically RAM just holds files that will be needed in the immediate future (or have been used very recently) to reduce read times on those files when they are needed. When it comes to actually running code, that is pretty much purely down to CPU speed. 1GB RAM is plenty to store a few apps and the background OS processes. When more is needed, older apps are closed (by "older apps" I mean ones used least recently). Otherwise, recently used apps are kept in RAM for quick switching. Unless you are trying to multitask in dozens of apps simultaneously, 1GB of RAM should be plenty for a phone today.
Both RAM and CPU has equal aspects on any device.
Ever tried playing GTA 4 on a PC with 1GB Ram and Quadcore CPU or on 4GB RAM with a SingleCore CPU...?
Both Ram and Cpu are important in terms of increasing speed.

The way I have always viewed ram is this; no, more ram than needed won't make your device faster, but it sure will make it slower if you don't have enough!

Awesome answer!! Thank you
Just like i thought!!!
"""""Under the hood, the Samsung Galaxy S III from Verizon Wireless is the same as the other US models. It ships with a dual core 1.5GHz processor and 2GB of RAM, which is meant to compensate for the lack of a quad-core processor that is found in the international version of the handset.""""""
JUST LIKE I THOUGHT!!! and above quote is from a major website!!!!!!!!!!!!!!!!!!!!
lol :victory::victory::victory:
More than 1gb of ram isn't needed. If you are on ics or jb, then you need a good gpu. If you are on froyo or gb, then you need a good CPU since they aren't hw accelerated.

Comparing PC with Android is a lil'bit out of the rails here. Even with one core and enough GPU combined with 4GB RAM should be enough to enjoy many things. More core's is good for multitasking etc. But when you think how many apps etc are optimized for those gazillion cores......

Its simple. Big RAM can hold more running apps or a single big app (more bunch of codes). In any case, there'd be high demand of processing. So, manufacturers can only add more RAM when they ensure that they have enough processing speed for better experience.
You can say, we have quad-core CPUs now, why can't we add more RAM like we do in PCs?
Well, the answer: Don't go for specs. Smartphone CPUs/GPUs aren't powerful like Desktop ones (despite same specs). There's power and heat issues, in fact.
Plus, Android and its apps are unable to use multiple cores with high efficiency (Intel advocates this; that's why it launched powerful smartphone CPU with 1 core). So, quad-core performs poorer than single/double core performance on PCs.
It limits the lifetime of a device since it cannot be upgraded and maybe manufacturers like that. RAM usually seems to be the limiting factor on phones running future versions of android. Its too bad it can't be upgraded like a desktop/laptop but thats the cost of fitting all of this hardware into a tiny phone.

AGREED! MANY DIFFERENT EXPLANATIONS! glad i asked ,all these helped. more ram would help but only to an extent. example if my wifes former htc design had a gig of ram it wouldn't have lagged so much running a single core 1.2 gig processor. FACT,so htc should have done it,it ran great till it attempted to multitask!:good:
Wasn't it stated during the I/O event that JB in general used less RAM and optimized apps better than the previous OS's so phones wouldn't need as much RAM as before?
It would be nice if JB or ICS had a timeout option for apps open more than a certain amount of time and would shut down automatically therein freeing more RAM. Obviously, it could be turned off or off depending on the user. Or if you could specify certain apps to close after an allotted amount of time if unused. Ex. Play store, calculator, calendar, SMS don't always need to stay on the page you left when you switched apps
Hi people, just a simple question that hope has not been made, do you think, in a short time (few months) 2 GB of RAM will be required for our devices to work well?
The most important is smooth and stable, higher RAM is not neccesary. :laugh:
Probably as tech gets higher, more ram will be required for later games and applications.

Cellphones today are the same as computer is... the higher hardware it would only be required to those who uses heavy features, like games and developing programs.
So, if you want a device just to basic use, you'll not need high spec cellphones.
It really depends on the usage, but there will be a lot of resource-consuming games released soon.
Some custom roms like miui also take a lot of memory! 1GB is getting short...

You don't really NEED 2GB of RAM, but does help. Better multitasking, mostly.
Sent from my DROID2 using xda premium
me personally i don't think that phones really need 2gb like gagdude said. I think if you have a kernel that makes the phone run faster then not necessarily 2gb is needed but helps alot.
Seeing phones like the new Nexus or the Galaxy S3 Alpha are coming out with two GB... I dont know if there will be apps or tweaks like that new one on the S3 Alpha that will not work well in our 1 GB phones soon.
i have a htc desire with cm10 4.1.2, it only has 576mb ram, but still kind of smooth, so 2gb is not necessary, but still more is better, because it will be more smooth, espicially when you playing games.
I don't think it's necessary and yeah you guys are right phones are like computers.
HD Screen
Quad Core
2GB Ram
Powerful gpus
If cpus would be x86 and with a mouse and keyboard you could get a fully working windows 7 on your phone. Even most of the computers at schools and libraries are not quad core.
I think ubuntu realized that and they are developing a fully functional ubuntu for phones with two and more cores.

Personally, I feel that 2gb ram is needed. Reason being that stock s3 uses around 700 - 900mb of ram. Of course, you may still say that you can install custom rom and decrease its usage to maybe 500 - 600mb. But if you run a lot of apps, it will eventually use more than 1gb of ram and the remaining usage will be send to and forth the swap(slower access).
Despite having zram which improves performance for devices with low rams, but ram is still faster than zram so having more ram is indeed better.
With a device that has to swap to and forth the swap and ram, battery life will be reduced and the performance will not be that good as the instructions of the code inside the ram has to be done then only it can be swapped with the instructions inside the swap and so it reduces the performance(in theory, you may not feel it unless you run something i/o intensive)
Go read up more on ram, zram and swap and you'll get it why I'd said to get a device with more ram.
Platform fragmentation on android will surely slow down this process. Also the maximum heap space available for a Java application (opengl textures and native code are excluded from this limitation) doesn't make extra RAM so important for many apps.
But for sure I wouldn't complain if my phone had more RAM.
1GB is enough. 2GB? You will play Asphalt 7 & Modern Combat 3 at the same time?

Not only your device is multitasking, but also you are multitasking.
I've got my device for one day already.
This is my first Sony Android phone and ... compared with my previous HTC old phone, Z2 is perfect.
However I find that the ram usage is terrible. There is only 1.1GB free RAM just after the device is booted up.
That means... the phone has used 1.6~7 GB RAM before I open the browser or games.
Quite ridiculous...
Is it normal? or what can I do for more free RAM
I don't think it's a problem but a good thing. Android has a smart/good RAM management. That means apps are kept in RAM until other apps need more. If you don't like you can try in developer option to play with "don't keep activities" and background process limit".
Right, you want your phone to use as much RAM as it can, this is a good thing. Also notice, the "unused" portion of RAM is also used to cache certain processes android believes you use often or will need. All of this is to speed up access to those applications as much as possible.
Take note on this
What is shown as free ram in linux is actualy freeable ram, your actual free ram is about 5mb
Linux has the motto of free ram wasted ram so when you have around 200mb freeable when your total is 3GB then there is a problem

I had Galaxy s2 with 821MB of RAM and i know that every app (not game) was eats about 20-50MB of RAM
I was sure that xperia z2 with 3GB of RAM it's more than enough but the reality is different
I see that any app in my Z2 is eats about 80-120MB! But why?
OK, maybe i know, because of tha resolution difference (in s2 800X480)
Anyone have any additional ideas for the increased RAM eating?
It uses more RAM because it can. In your S2, the OS had to ration what ram the device had between what the OS needed and what each app wanted, plus saved a bit for cached processes so overall everything would feel snappy. With 3GB of RAM, the OS has a lot more room to spread out, so it does.
Think of it like this, if your family lived in a 2 bedroom apartment, then moved into a 4 bedroom house, you wouldn't leave 2 rooms empty. Either people that didn't have a room to themselves would use them, or you would find other uses for them. Android is doing the same thing with the RAM.
You have 3GB, don't worry about how much RAM is being used, ignore it and enjoy your phone
Dont worry about ram at all, when ram is needed the kernel will free some ram up
Usualy you only actualy have 14mb free, your ram in your settings or most apps show freeable ram
Sent from my D6503 using XDA Premium 4 mobile app
I'm looking for a more accurate explanation for this fact
I'm from these users them uninstalling system apps and care to run with minimal battery drainage.
So, not received exact reason for eating the amount of memory unlike in galaxy s2

I was run with galaxy s2 on 400MB of free RAM and maybe 250 when running browser+gps+poweramp
This is not windows xp, its android and its healthy to have ram used rather than being free.
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
