That's such an idiotic advice!!!
You have 100mb free ram all the time and you are COMPLAINING ABOUT IT? How about to have 20 MB FREE ALL THE TIME? THEN WHAT?
You should really stop about complaining ram and read/understand how android/linux works. I am tired to say the same fu%%ing thing over and over again.
Don't use apps from playstore that boosts whatever part of the phone even if it is ram or battery...
Having 100mb free ram on your phone is good for the system.

Eeven I was wondering...
Even I was wondering why will anyone complain about 100MB? So what do you want 512MB of RAM free? :

Free RAM is irrelevant, Android memory management is unlike your desktop computer. It fills the memory with commonly used applications and only clears them out when you need the room for something else. So uninstall Advanced Task Killer, that sort of crap was deemed dumb/harmful years ago.

None of these new guys want to understand how this works.... and they keep opening threads about how small ram they have when viewing the ram from settings, that they have small amount of free ram... pff.... android can work stable even if it has 10 mb free ram. it is not like windows as Passa91 said...
When you play a game that requires alot of resources (512ram lets say), everything gets killed or resides in cached apps and the game runs smooth! When you close the game, the rest of the apps are restored....

Thanks all who reply to my Q.
I just wan a tell you guys im new to android so i dont have much idea about how its worked ok. and i dont had any issue with ram since i couldn't play temple run on my phone. It stuck my phone. then only i looked what is the issue. so i thought thats issue with ram.
Since im new to android from 512 ram its showing 90 -100 as free without running much application. That is why i ask about this.
any way thanks again for reply and i got the answer.

Why only with HTC?
I'm not arguing and I know how Android manages the Memory but still...
Why is this only with HTC? .
I have an Xperia Mini and my friend has Karbonn A9.
ALWAYS Karbonn A9 had more than 210MB of Free RAM and Xperia Mini had 120MB of Free RAM. I never thought like why is my phone having less RAM, etc. etc. but now I realize that it's actually a little sluggish/slow.
When I applied the ICS BOOT Live Wallpaper on all the 3 phones, Karbonn A9 and Xperia Mini could handle it very smoothly at 60FPS (it's a setting for that live wallpaper), but, HTC One V was very slow and sluggish.
Again when I played Raging Thunder 2 Lite on A9 and Xperia Mini, it was very smooth and my One V just couldn't handle it.
Any answers for this??
Is this just because of HTC Sense?

HTC One V, CDMA, running "Unofficial CM10 for PrimoC".
When I go into Settings > About Phone, it shows Memory: 333 MB.
The same exact phone running the stock ROM showed 512 MB.
However, when you add up the used and free numbers in both under Settings > Apps > Running, I get 334 MB on the CM10 rom and 362 MB on the stock ROM. I think there's just confusion about how the memory is being used and what numbers are exactly being displayed.

The memory displayed in settings is retrieved by the build.prop file. That doesn't tell you the total amount of ram the phone has. That's the total amount of ram 'free for user usage'. The rest of it is managed by the system but if you really want to see how much ram you have left on your phone go to Settings - apps and select running. Down there you should see the free ram you have, like in my screenshot below!

Haha.. Still got people using RAM Booster... I always said to my friend using advance task killer is useless... Even him using Note 2 complaining about RAM usage...

Holy crap.

Shame really, with all the phones being sold on Cybermonday and the recent RS $49 sale this community could be awesome.

[Q] Strange ram usage

Hello everyone!
I've searched all the webpages, but i couldn't find an answer, so i'll try it here!
So the problem is on my Sony Xperia S with stock rom 4.0.4.
On the Sony Xperia S, you have 1 GB ram, but 400 mb is prereserved for android, so you have 600 mb for user usage.
The strange thing is that there still is some hidden ram usage, because if you look at the screenshot, you'll see that the apps you can close in the task manager don't include the whole 600 mb, but only around 400 ~ 300 mb. I wanna know where that is used for, because 300 mb isn't much for user usage ..
Thank you in advance
ps.
sorry for my bad english !

Alright, and there's no way to stop those services?
And how long wil it take before the update arives? Because this ram issue is really affecting the way of playing games or just doing some normal web searching.. :crying:

It's normal.. I mean: everybody on Stock ROM has same usage. However, you said 300MB is not too much.. But it's not like on PCs: On Android every MB RAM free it's wasted MB. Android is managing RAM automatically, killing processes etc. in background to give another application more RAM (That's why more and more ppl argue about using task killers, which are useless in 4.0+)

That much free ram is normal. If you want more free ram, firstly don't use task killers. Secondly go to settings--->apps and force stop any apps that you have installed like Facebook etc which run in the background. If you force stop an app, it can never start on its own unless it is a system app. Thirdly, I don't know if you are rooted but if you have superuser access then just debloat your rom by deleting unnecessary apks like Music Unlimited and all other crap. If you don't know how to do all this then the best would be to just flash a custom rom as all custom roms will provide much better performance than stock.

300 - 400 Mb free ram is enough to play games... Android frees up more ram itself if its needed.

[Q] Out of RAM

Hi,
working daily with linux-OS and beeing actively using custom roms since Android 2.1 I have a bit of knowledge on RAM usage on Linux and Android. As many know and like to post "free RAM is wasted RAM" - we all know that. But why? Because all not actively used RAM (lets call it "free") can be used as a cache for applications you likely will need in future. But what if your GNEX runs out of free RAM an is not able to cache any more? What if you start a new huge application like your browser and free RAM has to be obtained to give it to your starting application? Yes - bad things can happen!
But lets start from the beginning:
1. If you go to Settings->Applications->Running you get the RAM-bar at the bottom of the screen. This is splitted in two parts: used and free (like defined above). Used RAM seems to be actively allocated RAM which cannot be used for other things like starting applications and free is the RAM which can be obtained because it only containes caches apps which are not running.
2. Directly above that bar you se a kind of brace which seems not to be just eye-candy but has some meaning: The lower and thiner part of that brace seems to show the part of that RAM (used or free) that is used by the applications/service in the list above. Example: if you switch to cached applications the brace will jump to that part of the bar and by killing some of the cached apps you will change the width of the brace.
Lets put things together:
viewing the used RAM you will notice that the brace does not cover the whole used-ram-bar but, in my case, about the half. I also noticed that the width of the brace does not change greatly with uptime of the device as all listed services will stay at their size more or less so their sum is not going to change greatly. In my case all services sum up to about 250MB meaning the braces width is about 1/3 of the screen assuming that GNEX has 700MB total RAM (the rest of 1GB total physical RAM is allocated to other parts of the SOC-chip like Baseband and GPU and not available to linux-kernel or android).
But one thing does change greatly!!! The part of the used-ram-bar which is not covered by the brace will be very small after rebooting and will grow with uptime. As the part covered by the brace is a fixed factor this means that the free ram is the trade-off for the growing uncovered part of the used-ram. In my case I get after rebooting the device: 250MB free, 450MB used of which 250 are covered by the brace, leaving 200MB used RAM for whatever (kernel, non-android stuff like filesystem caches, ideas?) After some days of usage this changes to 50MB free, 650MB used of which still about 250MB are covered by the brace, leaving 400MB used for other things (NOT app-cache).
Consequences:
From the assumptions above this means that android is not able to cache apps anymore (because they live in the free RAM) and my device beginns to lag while opening new apps. To obtain enough RAM for starting apps like browers (stock or firefox tested) it will even need to kill services!!! And in extreme low-memory situations it even kills the foreground app you are using (to me it happened while I used firefox). Also when you go to settings->applications->running again you will notice that android will be restarting your services over and over again to obtain more RAM without much success. In the situations my actively used firefox got killed something different happened: the launcher also had been killed because it was starting over but more importently settings->applications->running showed that much of the used RAM not covered by the brace was gone! Free RAM jumped from 50MB to about 200MB which is nearly what I get after a fresh reboot. I assume that in this extreme low memory situation also the kernel did clean up things.
From my observations you will get the following if your free RAM accoring to settings->applications->running is very low:
1. no cached apps if you swich to settings->applications->running->cached
2. laggy phone
3. your launcher gets killed more oftern when returning from e.g. browser
4. more apps get killed when returning to launcher meaning that they will get restarted if you return to that app
5. in low memory situations (app does not fit into free-RAM-part) services will get restarted frequently
6. in extreme low-memory situations kernel cleans up everything (i guess)
The question now is: what is using so much RAM and growing over uptime until our GNEX has no more free RAM? I alread checked different ROMs including stock 4.1.2, stock 4.2.2 slimbean 4.2.2 cm10-stable cm10.1-nightly and all of them show this behavior. The only thing I noticed: all 4.1 ROMS perform better in this area: their RAM does not fill up that quickly but it does. On 4.2 ROMs it takes just few days to run out of free RAM for me. I already wiped my device and installed only realy needed apps (20 out of 140!!!) but it still happens.

I think this happen in any OS
A daily reboot is always a must in my opinion, to free ram, to stop some services, to stop wake locks, to stop battery drain without sense..

That's what always makes me ask : Is Gnex really have 1gb of memory?
Other phones with same spec. uses same OS have more than 693mb that in gnex , why the hell our phone has the lowest read ram in 1GB category phones
I'm sure this is the only weak-point in gnex

300MB is GPU reserved for camera.

Sent from my Galaxy Nexus using Tapatalk 2

I didn't engineer the device. But I presume it's a requirement by the GPU PowerVR chip, since it uses alot of RAM on the Nexus S, which had the same chip only downclocked. It was 330MB usable out of 512MB advertised there. The amount reserved is bigger on GN obviously because of HD video capture option.

I agree GPU shared system RAM, but 300MB is wayy too much bro. I checked my N4 it has 1.82GB of 2GB total considering N4 Adreno and camera chip is more powerful than i9250

It's (again probably) not because of the speed/power etc. but that it's like that by design. Adreno ain't the same as the one used on GN, so there's no comparison.
I'm sure Google didn't allocate that much memory just to screw us up, but instead there's a legit need for it. For instance, the amount of RAM available on a Galaxy S2 is much bigger, around 830-850MB out of 1 GB and it has a completely different camera/GPU combo, spite full HD video and 8 mpix instead of GNs 5. That's why I presume it's just PowerVRs "fault".

Perhaps, i just checked galaxy tab 2 ics available ram, it less than 700, but after flashed stock JB, it shows more RAM, about 770MB. Tab 2 uses OMAP and PowerVR right? Imho. i just curious why it reserves so much ram. Searched google and can't found the reason :S

*Update*
An galaxy S2 with all stock (Android 4.1.2) shows the same amount of used RAM after 10 days of uptime (380MB free and 380MB used - a nearly perfect 50/50 ratio). No sign of degradation so far. Honestly this phone is not used much but still it feels very different from what I see on my Gnex.
Has someone shorlty fully wiped and reflashed his phone to stock 4.2.2 (JDQ39). How does the RAM usage look like after fresh reboot?

RAM problem
This is what i get today. Using liquidsmooth 2.4 fraco kernel. But i know its not abut apps i use. I dont know where are all that RAM. After reboot with same apps runing in background i have 230-260MB free RAM. But if i using phone day or so it look like this.
Phone get laggy, slow with high latency. Im not sure if its 4.2.2 bug for Gnex or just some mess with ROM but its same on any custom ROM. ill try flash stock and see what i get.

Hi, this is exaclty what i was talking about... very frequent service restarts and laggy phone and even basic things like keyboard and music-playback can quit while in use. While I tried to compose an email to send a screenshot to my desktop to post it here my stock-mail-app died and the phone rebooted. At least I have now both an after reboot and an after two days of using PARANOID ROM screenshot
I recently switches to PARANOID 3.55 and now have even more issues as the phone boots with just 200MB free RAM. This ROM seems to demand very much RAM.
BTW. I installed Stock for more than a week before switching to PARANOID and had around 260MB free after booting and around 150MB free after some days of usage. Increase was ways lower than on any custom rom. Can anyone comment on this? Same or contrary stock-experience?

Stock JDQ39 rooted. (running one week)
kernel stock or lean both are perfect and have no affect RAM or smoothness. Screenshot is after some days of full usage. Battery life i getting is about 1day with 2h screen on.
now someone tell me that its not custom ROM problem. 4.2.2 stock is just awesome. Im sad that custom ROMs not..

I thing you ment odexing some custom ROM, right? I'm thinking about to try the odex-me apk you can find on XDA which will odex all apks from /system/app but leave the framework.jar stuff untouched. But its far more easy to deodex the stock ROM and to try again

How many memory do u have in use? (Settings>apps>running)
And how many free?
Enviado desde mi Nexus 7 usando Tapatalk 4

right now it's 256MB used and 85MB free
the free space is lower most of the times though

Mmm, more memory free more fast will be the phone.
Try this, change your launcher for nova or apex (I recommend an old version, which use less memory) then configure the launcher to be fast in options.
Set the frecuency of the clock to max 1306 min 364
Use ondemand if you feel slow, but for daily use I recommend smartassv2.
Change the kernel to Vengance is the fastest that I ve ever try.

uhhh, stop there. Not all the time, as long as you have a good governor, I/O and decent CPU frequencies, phone shall be fast independently from the used/free RAM, an example is my phone with even 50 of free ram and blazing fast, Android has an awesome memory management, I'd advice not to take this too literally. Free RAM is good, but most of the times it's being used on the stuff you see at your screen, which lowers the redraw speed, and hence, the lag and slowiness.

For lags? Don't overclock, my phone runs smooth even on 576MHz, so as I can see you're on ICS, have you tried GB or JB? idk how many people do report lags on ICS, we already know it's the most laggy OS unfortunately.. which governors are you using, have you uninstalled useless system apps? do you use task killers/cache cleaners?

I have a friend who uses a Xperia S on stock JB. He claims that there is not much difference in the performance from ICS except for some minor changes in the looks. I have yet to test out the stock JB myself so I don't have much say about stock JB performance.
And the official statement released from Sony was that JB would not run optimally on 2011 Xperia phones, that's why there's no JB update for our phones.

Yes, it is normal.
Simply put, Android has complex - dynamic - ways of using and re-using RAM space.
As long as you don't see messages like "unable to start program", you're on the safe side.

thanks bro :good:

Its normal. It doesn't benefit Android to have RAM free, and in fact its usually more efficient to have RAM as full as possible. This lets you quickly access commonly used apps, instead of stopping and starting them every time.
Also, be careful about using task killers for many of the same reasons. Freeing RAM has little benefit, but constantly killing and restarting tasks can actually impact performance, battery, or cause other issues.
