So, i've installed the 452 CH firmware with prerooted img yesterday.
I am experiencing quite "high" ram usage, with almost all applications closed via the system (not with a task killer) i have "only" 200mo ram available.
I used to have around 400 with GB.
Is it the same for everybody or do i have some bad app using all my ram ?
I've heard that ICS was better at handling cpu & ram ressources but i'm still a bit surprise by the difference between ics & gb.
This is NORMAL. Live with it.

it a Linux/Unix system... that means, the Ram is allways full - but dont care, thats give you more speed to launch some apps... and if you look nearly, mostly every process in Ram is flagt as "inactiv" or as "empty" - so if another application will need more Ram, this emty and inactive processes will be kick out of the Memory.. A full RAM dont means in a unix sys, thats no space for forground applicationd..
its also god for your CPU and Battery usage... because a Application wake up out of RAM need less CPU then boot an Aplication from the Ground... and less CPU means less batteryusage
its a Linux, not a Windows :laugh:
Okay, it's a bit like windows 7 memory management compared to win xp.
Thank you

Well, I've upgraded to this device from a Xperia Arc for some reasons. 1GB of RAM, one of the best dual core processors around and 1080p recording. Xperia Arc had only 512 MB of ram, leaving me with only 320 for everyday usage, and with GS2 I'm getting around three times more RAM, but since I've updated to JB on CM10 codeworx build, I'm getting less than 200 MB of free RAM. I know JB uses more resources to enable VSync and 3x Buffering, but is that normal? That's too high for me, and I don't see me back into the ICS roms.
Welcome to the club. JB uses more resources, probably won't change.

It's normal..don't panic..by the way, empty ram is wasted ram..just enjoy your awesome phone..if still in doubts, see the ram usage of galaxy s3, the best smartphone..
If you're asking if it's normal for people not to use dedicated threads for CM10 questions, yes, it seems that it is.
If you're asking whether it's normal that using a ROM which says:

at the top, for people to then ask for support, yes it also seems that it is.
Also, the ROM was known to have a memory leak last time I looked. You can find out yourself if it still does by reading the dedicated thread. You can start here:

Yes it's normal, but most of those RAM space used are for cached processes just to make things faster. More ram will surely be freed when you need them.
This is the only reason why even though the free RAM looks small at startup, you haven't experienced lite memory, or apps force closed due to low memory warning

Hi everybody, I'm Gabri, I've bought this nice Lg L9 II and I need help
The phone is branded, and out of the box I found already installed in it Android 4.4.2.
After having stopped and disabled the unwanted brand apps, I checked the resources and I had a bad surprise. Considering that the specs are 1GB of RAM and 8 GB of ROM, I have only 240 free MB of RAM and 3.07 GB of ROM available. And I haven't even installed any app or started to use the phone. Is it normal?
Thank you four your help / advices guys.
Yes it's normal. The 8 GB storage is divided in two partitions, 4 GB each. One for the android system and one for apps, music, photos etc. The pre-installed apps are using 1 GB of the second partition so you have 3 GB available.
As for the RAM many apps start running by default when the the phone boots (keyboard, dialer, sms, maps, weather etc) and the system automatically stops some of this apps to free RAM when needed to run other apps.
thank you l3t0m,
this makes me think that kitkat is very eager of resources, so how is it possible that you can find kitkat also in devices with only 4GB of ROM and 512MB of RAM? considering that my phone has 8GB and 1GB and more than half of both are already taken by the system....
One more question: the used RAM memory is 523MB (even if the processes in the list of the active apps do not reach that amount of occupied RAM at all), and the free RAM is only 240MB... so where is the rest of memory necessary to have a total amount of 1GB??
Sorry for such a kind of questions, maybe the everyday experience with the device is still satisfying and one should not worry about this stuff (yet I don't have a direct comparison with previous android versions in my device), but I simply would like to understand if everything is ok or maybe I need to changes something to have the best possible experience with this nice L9 II.
Thank you!
The devices with 4 GB ROM have about 1,5 GB available for the user which is obviously not so much considering that many popular apps are taking up to 100 mb and if you use a GPS navigator the maps also need some hundreds mb of storage to be downloaded on your device. Add to this the frequent app updates and the photos/videos you shoot with the 8MP/1080p camera and you will be out of storage.
I think that 8 GB is the minimum you need to have the best experience with a device like the L9 II.
I have no idea why the rest of the 1 GB RAM is not showing (that's happening on my device also), maybe someone with more technical knowledge could explain this. Anyway, as far as the device works fine (and it does!) there is no reason to worry about.
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
