I have freezed the unuseful apps and im usin startup auditor, Why my ram is still too high? What can i do? Please help
Try Supercharger or [email protected]'s scripts. The threads are just a few blocks down.
Well v6 isnt effecting too, i used build prop. i wanna use local prop. its effective.
I use auto memory manager and my ram stays between 90 to 120 without any special scripts!! Try it and tell me if it wrks

Not ram manager pro ??
IMO having less ram is not a good idea in android device. android device has different ram management. when an app is started, it will be stored in ram's cache to make it started faster when it started again. when the ram is almost full, it will automatically delete ram's cache and stop some some app. in this way, android devices will have better performance and battery saving. its almost useless to clear ram except in some cases when we need a huge ram space to run a big program.

I dont understand you. When i clear ram its 80+ but now its 130+
Kurotsugi post is cent percent correct.
You shouldn't run after cleaning your ram
I'm having 220+ ram for average use. my zenonia 4 is running smoothly and never got a problem with any app. as I've said, android device will store recently used app in its ram cache. thats why the ram usage will raise rigth after you clear your ram and start to use some app. this is normal and won't affect in your device's performance much. I thought our ram setting is balanced between running app, background app, and system app. you can change the setting with ram manager pro or minfree to have more space for running app and background app.
Exactly! So much of fuss about RAM. My RAM consumption is always 240+, even after a reboot. Never had any problems.
Woah 240+?? what u are using?
dont forget,only used ram is good ram in linux(android is linux).greeeeetz

240 is my minimum RAM usage. Well, Go Launcher, Go SMS, Go Notification, Go Locker and AI Type Keyboard are always running in the background. xP
Try [email protected] scripts
Try [email protected] battery and RAM Saver , Im using it and my ram is just consuming about 132 - 109
Im supercharged. It'l conflict.
more RAM = more battery consumption ?
more ram doesn't always mean your device will consume more battery. yes, its true that our device use more battery power to start up the program, write the onto the ram and run them. nevertheless, linux have unique method to save more battery. after a program is minimized, the program is not erased from the ram. it will be stored in ram's cache. in this way, our device could start the program without write the program onto the ram again. this method will avoid to repeatedly write and erase the program on the ram which consume a lot of battery power. this is also the reason why most android program doesn't have exit option.
owwww , thanx , i hav a bad habit of clearing ram every now and then , even if it is at 130 or 150 ..
m not gona clear it now unless system be lagging
that's normal if you have 160 ram that's the lowest ram that i've reach in my galaxy y even i press the clear memory its still 160 or below... if you feel that your galaxy y is lagging why you dont want to try Andrenaline Engine that imbawin made even if you reach 200+ ram it still fast even your ram are 60MB left
(Moderator, i posted this here because this it's a solution about the lack of RAM on Defy running CM10)
Hello people!
We are all excited about the Defy with CM10 Jelly Bean
But there is one thing that many users are complaining like a grumpy old man
It's about using too much RAM in Android 4.1.1 on Defy
Well, first I want to say one thing:
WAKE UP PEOPLE! IT'S ANDROID OS, NOT WINDOWS! :good:
And now comes the old explanation about RAM on Android:
- The Android OS is based on Linux, as everyone knows. The system features a smart task manager that handles all apps minimized to the re-start of apps more faster.
When the system needs more RAM to run any app, it kills unused apps to free up more RAM. And it will be that way forever, because that's how it works with the linux memory management.:angel:
End of this beautiful love story.
[Q] - So my friend Salo-S, why my Defy uses so much RAM in JB?
- I just finished explaining right now. But however, I have not seen any lack of free RAM on my Defy+, is always at 185 ~ 230 free (open with some apps, like Google Now or WALKMAN player of Xperia S).
[Q] - And then? what you have to do with that?
Simple. Check what apps are consuming as much memory as you describe.
Probably you installed an app that consumes a lot of RAM.
Solution: Full-Wipe IT. Reinstall the CM10 and now pay attention to their apps.
[Q] - Oh Salo-S, my phone keeps in low memory like 100 ~ 85 free.
Ok, then do yourself a LITE version of JB!:cyclops:
How? I explain.
My wife has a XPERIA X8 which has only 185 RAM running good the CM9.
Witchcraft? No, it's just removing unnecessary content as LiveWallpapers, Dev Apps, Google Apps and some many other apps that do not affect the functioning of the system.( Something like a LITE version of ICS )
185MB of RAM the phone has, ICS runs well with only 40 ~ 50 MB free.
I do not think this is useful in Defy with JB, but try!
This is the solution if your Defy loves sushi of RAM memory.
The Android system has a great management of RAM, I think all this unnecessary.
It is the explanation and tips for users with RAM problems, I think this will help ..
Right now friends, we can stop asking about the SWAP on Defy (we have locked bootloader) and stop talking about low RAM. This all explained now.
Thanks to Quarx and Epsylon3 to make JB possible and good on our Defy's!
Thanks ,
nice explanation !!
but still this thread is more worthy of general section

thought so....
It might sound rude to fans of Task-Killer apps and V6 Supercharger (it works, but not for everyone),
but Salo-S is right. Even with task killing, it only temporarily frees up the RAM, but if you have a lot
of apps installed, the RAM will fill up again in a few minutes.
So the best way to free up ram on a low-RAM device like Defy and Defy+, is to limit the number of
memory-hungry apps in your phone.

you can install as many apps as you want, you just need to avoid that they start automatically. i use this app and it really helps to control when which app starts.
hope this will help you guys
@salo-s
basically you were right. but have you ever read some posts in quarx' cm10 thread?? it is a fact that our defy runs very slow with cm10 and 50-70 MB free RAM (or less). This happens when you flash full gapps and some favorite apps. if you flash minimal gapps (and also some favorite apps) free RAM is about 120-150 MB and the rom is very smooth and responsible.
some useres think it's a cache problem. more free ram = more cache = smoother system.

That doesn't matter.
It's a guide, you're not developing anything, therefore it doesn't go in the Dev section.

Very good explanation on the way Android Memory Management works.
To extend on it, people you can use AutoKiller Memory Optimizer app from Play Store. Using this App you can increase the Minimum amount of RAM to be free. Basically, this app is not a task killer but is just an extension of the natural Memory Management system in Android as it helps you customize the Amount of minimum RAM to be free and change the value of RAM to be consumed by the Non-Active Apps etc.
I have been using it for months now (on Stock Froyo, CM7, CM9) and it has been working it's magic ever since.
Hello guys,I'm using BioHazard_W v.4 ROM, and the RAM usage of it's pretty high, how to lower the ram usage on it?
It's always over 240mb from 350, I wan't to tweak that RAM usage to 150-200 normaly, any advice on that?

240 MB used out of 350 MB ... that means 110 MB free.
That's a respectable number.
Now let me tell you one interesting thing about Linux : free RAM is useless RAM.
Whenever possible, Linux will leave you with as low free RAM as possible, and use the rest of the RAM for caching. This will not only make the system goes faster, but -- in case of portable devices -- reduce power usage as most of the most-often used data is kept in memory, saving the device from having to access a storage media (which consumes more power than accessing the RAM).
So... if your system is not suffering from endless lags and redraws... just ignore the RAM usage.

Btw, my phone had 40mb of RAM free right now when I checked, and I can't multitask successful, when I minimize something and open something else, then, when I decide to open the previous app, it reloads again, and I just wan't it to be on RAM and minimized.
Any suggestions how to make the multitaskin way better?

In that case, try cutting down on apps that continuously run in the background.
In my phone, apps that run in the background are : Google+, Avast!, Pulse (update every 3 hours), Tasks+, Widgetsoid, and CPU Tuner. All other apps I prevent from starting using AutoStarts.

I have rooted kindle fire with JB ROM on it. I am using it for a month and I don't have problems with anything and the battery is OK it's even last longer than with the original ROM, but my only problem is that I have very low ram memory, I have only 50 mb and even when I kill all the APS I get to 90 but in seconds it all get down to 40-50 mb free ram. So if this is fine and if it is like it should be then ok but If it is only me than anyone know how to fix please write to me?

Ancient thread, but I will resurrect rather than create a new one. Free memory doesn't matter so long as the system is able to recover used memory when needed. Take a look at the Running Apps and see what things are big. Facebook is a 50MB memory pig. If you don't see many running apps but free memory is low, your rom might have a memory leak: reboot and see if the numbers are better on a fresh system.
I'm running CM11 M11 (4.4.4) on a KF1 (512MB, 401MB reported). After a fresh reboot I have ~270MB used, ~130MB free (Settings | Apps | Running). I can get a couple of weeks of uptime but M11 has a memory leak so free gets low and the system eventually thrashes.
I'd be interested to know what the memory use is like with otterx or slimkat if anyone could post those numbers.
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.

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
