[Q] How much free RAM is decent ?

How much do you have normally ?
I don't use task killers, since I've heard that using them is pointless

For me about 110 - 130 mb for ICS to keep the system smooth. GB probably a bit less between 90 - 110 mb should keep it smooth.

Free RAM is wasted RAM!

But the Arc (S) needs 55-80MB free RAM or it slows down a lot

I have around 100mb free, using ICS virtually stripped down to Vanilla ICS, only got the Sony customization on that I need like Facebook inside Xperia, Track ID and Music Player.

I don't agree.
Although Linux manages ram efficiently in that you don't really run out of ram since it re-allocates, you still need 100mb + in ICS for it to be smooth (well, at least non-frustrating).
With more free ram and a script like supercharger I can load essential apps like dialer without having to wait a few seconds each time I start it up since there is sufficient ram for me to run other apps without it automatically killing apps in the background.

[Q] Ram issue on HTC one V

I just have less ram free all the time ( less than 100 mb ). I have only few applications running. can anyone tell me why is this happen and how to increase free ram.

This will help

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...

[TUT] - Explanation about the RAM on Defy with JB - How to improve it

(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.

[Q] Available RAM issue

Hi all. After flashing TrueAncestor 1.6 LE, I had about 330-340 total available ram (free + used by running apps). This was a long time ago, but still is like this if I reflash it.
The issue is on my running apps tab it shows only about 240 mb total available RAM! When I restore the backup, that is. I don't really know how or when it happened. Maybe it's due to installed apps, but I can't really find out how is that possible.
Edit: I found out via advanced restore that the problem lies in the data backup, but I can't figure it out.

ram or internal memory btw?

Try run sme RAM killer app, like GTA Vicecity ... then exit game a check free RAM ...
BTW - on my Xperia S (1GB RAM) i have frree only 250MB and no problem at all..

ram. it's not that i have a problem, it's that 100 mb of ram somehow disappeared. i flashed another rom and i'm doing an app-by-app restore with titanium backup to avoid restoring whatever caused me that issue...

It is because of the app, also maybe the kernel n the rom u used, i used turbo kernerl jb+ jellyzeus rom, superb fast, no lag at all, smooth when play games, although i got 100mb out of 377mb,
Sent from my R800i using xda app-developers app

Check the CosmicDan's sig "free ram is wasted ram" when apps will need ram they will just free it by themselves. I'm having max 180-140 ram in daily use which isn't much and everything works fine. Either way 330 mb of free ram - WTF? Yeah it's caused by apps. Many apps are running in the background or just idling. It may be that rom itself does something which will eat some ram to make itself smooth and then free it up when needed.
Short version - it's okay, don't worry.
Sent from my R800i using xda premium

mmh... seems like i've not explained the problem well enough. I know free ram is wasted ram. I'm talking about the total ram. By total available ram I mean free ram + ram used by processes you can see in the "running apps" tab. The 330+ mb of *total* ram is what one should have with this phone. I had only 236 mb. I did a reflashing restoring app by app, and now I have like 300-310 mb of total ram. That's still kinda disappointing since I don't know how is that. Out of the 512 mb installed, system processes which are unseen by the "running apps" tab in settings take some, and that's okay, but to have 236 mb total means there was some other invisible process that was either disguising itself as a system process or letting the phone believe it only had that much total ram.

You should used custom rom n kernel, some stock rom isnt that great,
Sent from my R800i using xda app-developers app

there are many users with stock rom and kernel which get 360+ mb of total ram, your answer is not helping that much. Also because i'm not using stock rom lol.

No, i mean sometimes u need to flash stockrom to get corect baseband n then install the rom, it just to avoid any prob after,
Sent from my R800i using xda app-developers app

well, i found out that it doesn't depend on the rom anyway. When I link the phone to the pc and the sd unmounts, it all gets right, the total ram is what it should be, but just for the first moments, then the total ram is cut down by a lot but i think it's normal. When i take the phone out it regains all the ram, but when the sd mounts again, something like 40 mb of ram disappear just like that.

sorry for double posting, but I realized other things:
actually, the ram programs like setcpu and quadrant is the correct 367 mb.
Unmounting the sd card eliminates the problem as long as the sd remains unmounted; mounting immediately brings it back. Messing with dalvik vm heapsize does nothing, engine flushing with supercharger does almost nothing. I absolutely don't know what to do. Even my older screenshots from when I didn't flash anything has like 330-335 mb total ram, instead of the 345-355 it should be. Now it's about 305-310. More than 55 mb are not reported by running apps and this affects gaming, as ram heavy games like 9th dawn, everland crash and aralon + gamekeyboard can't stay in background together if the graphics options in aralon are maxed out.

If it still persist u should try uses swapper. Great way increasing ram,
Sent from my R800i using xda app-developers app

I am too facing this issue, after booting I have like 340 mb of total RAM(100MB in use and 240mb free) but after using phone for quite a while the total ram decreases a lot(110mb free and 100mb) in use, where is rest of the ram?? how to recover it?

U just cannot recover the ram. U should better try the new rom. Try atomic gb rom. It fastest and stable. And u should not get to furious about ram. Just see the phone lagging or not.
Sent from my R800i using xda app-developers app

Well, i have 380 total ram. Flash turbokernel 3.1 and then any JB rom and then you should have the same amount of ram that i do.

[Q] [Q} Acro S low RAM problem

Hi there,
I have a question to Xperia Acro S users: How much total RAM can you see and how much free RAM on your phones?
I have my acro s since few days and I'm a little bit disappointed. In normal use I find it a bit laggy and slow. I tried it on 6.1.A.2.45, 6.1.A.2.55 and XTXperience_9. All the roms the same problem. I installed "Android System Info" and it showed total RAM 634Mb and free RAM 196Mb.
Both my previous xperia p and my tablet ainol novo 7 flame are showing total RAM 809 Mb and more free RAM. Each of devices has 1GB RAM according to official specs.
Why there is such a difference? Anybody knows? Is there any solution?
I installed additionally "Quick system info PRO" but the same results.

Answered many times before and saying this again
From the Total 1GB RAM, around 200 MB is being used the by Adreno GPU. Some are kept reserved for the OS and rest amount of RAM we get for the apps and general use.
I am using Firmware 0.50 and honestly i don't feel that much of lag actually. If you are on Stock ROM then try this two apps from Google Play.
RAM Manager Pro and Pimp My ROM. These are really great tweaking software.
And it's not about how much free RAM you have, it's about whether the RAM optimization in your device is good or not.I have only 130 MB free RAM but my device runs quite good.

People are far too ram obsessed. U could have 80mb free and you'd never notice unless you looked. My advice. Just stop looking and use your phone

Thank you for your reply, specially because you've written about it before. I've searched xda for this topic, but didn't find answer.
I know some of RAM is used by GPU, and some reserved for system, but I wrote the question because my xperia P and ainol (both 1GB RAM) are showing 809 total and over 400 free RAM. I wouldn't care about it, I wouldn't even have checked it if I wouldn't feel my acro s very laggy comparing to my mentioned devices. Both are worse in specs than acro s.
I'm running 0.55 stock ROM right now, I'll try the apps you suggested. I bought my phone a week ago, and hoped to be more satisfied than with xperia p (no micro sd, no watherproof, smaller screen, and so on). Now I think xperia p works better for a daily use ;/

No problem. Sometimes some apps like Facebook or Google play consume high amount of memory like 80-90 MB while opened for long time. So try force close these once u have done using those apps. If the RAM properly distributed then even if you have 70-80 MB free memory in total it shouldn't be lag at all.
