How to have more free ram ??

Which kernel should i choose ??
i use DjangoManouche 1.5 now
i have a total of 330mb ram only
any good idea i can do

I believe you have 330 mb because the rest up to 512 mb is reserved for system apps. So you can use root explorer and go to /system/app and remove some system apps you don't use and reboot the phone. Just be careful not to touch stuff that is required for the phone to boot. And no, I don't know exactly which these apps are. But here is a tip: I always remove gallery, news and weather, all google apps, music player, stock email, navigation software if there is any, live wallpappers, file explorer (not before getting another though) and everything that's about visualization in general. These things are safe to remove.
And btw the amount of free ram is pretty much irrelevant to the phone's work because the kernel tries to utilize as much ram as possible and then it gives it away to ram requiring apps for the moment. I am just trying to say that you need not worry about free ram if the phone is working correctly. And if it's not it is most likely not because of used ram but some app is not behaving as it should and is using the CPU too much.

You should consider using a kernel that has OTF settings or a RAMhack. I recommend Etana but for some reason I love Temasek's Kernel. They both have the RAMhack option. It basically takes some of the RAM that is reserved for your GPU and makes it available for your device so you'll have more RAM for running applications etc. You shouldn't set the RAMhack too high though, 32mb/48mb should be fine. Additionally you could freeze some system apps that you don't need and use an autostart-manager in association with a task killer to kill applications and not allow them to restart themselves.

No.
And I heard that ramhack cannot be used with stock rom.

if some1 comes up with ram hack for stock based kernels ill be back to stock right away...

Gueste OC 1.8.1 stock kernel is awesome. Activate z ram in it and u will have really fast phone .

What did I just read?
Don't do what was posted, you'll most likely break everything.
System apps uses system storage not ram. Deleting those apps will not give you more ram. But more system storage maybe.
Ram is used to save the current state of opened applications. Though the reason you only have 330mb left, is cause the gpu uses it as shared memory.
A ram hack is an option, as it reduces the amount of ram that goes to the gpu. But the use of a ram hack over 48mbs will break lots of things, such as recorder, camera and instability in games.
In all honesty, there is no use for a ram hack 330mb of ram is enough.

If you use DjangoManouche you have ram profiles, another option are to use swap, the benefits, i'm not sure there are
Like a previous post said.....android are coded to use all ram except the amount needed for system to run smooth, apps you open will then be stored in ram which are the fastest "sd card lol". Next time you open its from ram. If you use many apps its useful with much ram. After reboot you start all over again. If there's a memory leak you can get issues like lagging Best solution are to choose a profile with much ram for apps and not much more than nessesary for system
Our device gets better each day thanks to our amazing devs

Use guestekrnl 1.8.1 and enable ZRam, works a charm. See my recent post in the flix123 v20s thread as well.

What are you planning to do with the free ram?

Sell it on Ebay! :good:

To have more free RAM means it has to take some from the normally non accessible system dedicated RAM. This way your device has less RAM for things like graphics which can worsen video playback and record performance.

The opinion free ram is wasted ram is wrong. you should realize it from daily use. its because when you have for example 70MB free and you open browser with some tabs, some game, etc. it closes other apps you dont want or it closes some of the tabs in browser and you have to load them every time you switch them. you need enough free ram to open what you want without system automatic closing other and under 100MB really isnt enough

This doesn't make sense. The system will get you the ram you need whenever you need it.

Beggining to think android requires ram.

My nexus 7 (stock rom)starts to lag when it has like less than 100mb free. Lag goes away when I close out programs manually. This is the same case on my galaxy nexus (cm10.1). But my nexus 4 is great and worlds another might I add. But back to the 7, does any one else agree or have similar problems?
Sent from my Nexus 7 using xda app-developers app

I'm affraid you think right. Apps need memory to run, when this RAM is low or there is not enough available to start a new task the system lags, especially it's UI. Then it attemps to force kill one, more or ALL of your previous used apps depending of your memory usage level.
We can nothing to do with that, just can adjust our number of "same time running" applications to something appropriate to our device memory.
Sadly I have to say that for real MULTITASKING 2GB RAM are THE MINIMUM these days, but for really fast and smooth reactions 3GB will be the optimum. Where are these devices you can ask, hah they are NOT BORN YET...

AW: Beggining to think android requires ram.
I think I'm doing something wrong.. Because I never had ram issues.. :/ I'm trying to make my tablet sweat this week ^^

Me neither. I had a Viewsonic GTablet that only had 512MB of RAM, and it wasn't an issue.

It's probably not so much android but the apps. Just like all computing, programs get better and more complex and start requiring more ram and processor power. I think with the Nexus 7,it has plenty of processor, so ram is probably the bottleneck.

You reminded me of my lg p350, 175mb ram and was so slow, and thats with the os fitting in it, Froyo.
1.5 horrible and torturing years later, here i am, with 1gb ram and enjoying it.
Be thankful you even have a gig of ram.

Maximum RAM used

Hello everyone! Having a 2GB RAM in nexus 4, I am curious how much max RAM have you people used. After running my daily apps like Facebook,8 tracks, flipboard, what's app, viber,xda, drop box, chrome, I have used a Max of 1.2GB RAM. Post your max RAM usage.

Lol. Yup. That extra ram Will be much helpful for the future updates. My friend's one x's 1 gig of RAM is now not sufficient for him.
Imho, nexus 4's power has not been used to the full yet. Optimization needs to be done, both in hardware and software. I believe we have a hardware that will go into full swing next year

Most likely key lime pie will have more optimizations hopefully and it should debut this year.

That is true. Take for example the galaxy nexus was released two years ago and its going strong

I dunno why 1gig of RAM wouldn't be sufficient but i don't mind having the extra. And KLP rumors say that the new Linux Kernel will actually be substantially more RAM efficient.

i usually have between 1375-1500mb free ram at any point of my usage(about 1650mb after killing my apps). i also use autostarts to prevent apps from starting up in the background, and i use greenify to tame wild apps.

I've seen about 1.2-1.4gb of my RAM being used. But there was someone who kept complaining that the nexus 4 would close apps even if plenty of space was remaining. i think that person even started a thread & posted videos to prove it .

anyone can fake that video. can even make it kill the background apps sooner when very little ram is used. all you have to do is change the memory management variables by raising them. plus, there are roms out there that do that too.

Yes. I feel like that nexus 4 kills certain apps or refreshes despite having enough RAM.
Sent from my Nexus 4 using xda app-developers app

Using Elixer 2 widgets, I seen to hover between 1.2gb to 800mb free ram. I don't really close anything, pretty much just let it run on its own. Stock not rooted or anything. I have probably 50 give or take a few apps installed.

Ram use age is not only dependent upon the applications running... If you use roms like xylon or liquid etc there are options to show how much ram is used by applications, cache and one other thing which i can't remember right now.. So basically my ram use age in real life had always been nearly to 1.6 1.7 GB!
Sent from my Nexus 4 using xda premium

is jelly bean optimized for 2gb?, Ive had apps close not crash and I wonder why if it needed the ram, would changing the vm heapsize help?
I checked and I usually have 700mb remaining.

My Galaxy Nexus ran perfectly with 1gb ram so its probably more like JB uses ram pretty efficiently. More helps tho.

That much RAM? you are on a custom Rom? Could you list your apps?
Sent from my Nexus 4 using xda app-developers app

Maximum RAM used on my N4 was about 800-900 MB. Stock everything, with some services running like Facebook,Whatsapp,8tracks,Lightflow and a live wallpaper ..
As for the people wondering why some apps appear to "close" on their own despite having enough RAM. Its the app's fault, the code is not written well and does not advantage of Android's multitasking capabilities.

Mine has free 900+ mb

I don't use that many apps..and yea iam on a custom rom...but i guess u didnt get what i am saying...most of the time what ubsee ass ur free rom isn't actually free... It's being used by cache and other things...what most roms show u is only how much ram applications use..as u can see from my screen shot... The phones ram is never entirely free !

Task killer too agressive

I've noticed that my browser gets dumped from ram quite often, even if I don't use a different app. It seems to be time constrained.
The reason this is so annoying is I really hate when the browser has to refresh the page.

Can't corroborate. I've had Chrome sitting in the background for over a couple hours now without it requiring a refresh.

****. I'm concerned about this because my old nexus 10 would do the same thing. I wonder if 2GB is just not enough memory for these high resolution displays. A good chunk of it goes towards video memory, leaving less for the OS to work with.
My stupid n10 would constantly dump tabs on chrome, no matter the type of rom I used (stock, aosp-based CM and AOKP, or just random aosp builds)

Thing is, it's retarded because there's always plenty memory available

This is not all about the overall free memory... This is about the threshold of the OOM of android. If I had the HTC One right now I could explain it to you easily but sory my answer right now is too generic so just search what those are...
@greengoldmello
There's no such thing as "dumped on RAM" as all active apps are running on RAM. Once they are flushed/removed from RAM that's the time your apps refresh when opened again.

[Q] increasing RAM on Optimus 2X

My mobile is getting slow and when I checked the RAM, it is showing that it has 342MB RAM and usually it is 50MB free and by using RAM Booster, I was able to increase the free RAM. But, is there any way I can increase RAM of the mobile, as my mobile is getting very slow and sometime, I have to restart my system, and even power button doesn't work and i have to take out the battery and put it back...

In android free ram is wasted ram theory....so if things work normal...it's ok
But if the problem is getting slower and no response...then best is use greenify app and make the apps to hibernate....
It works to some extent....But then it is better to use min free manager too
Sent from my LG-P990 using xda premium

it also depends on what rom are you using, it has effect on ram usage. for example I'm using tonyp's cm10.1 and everything works well. I never check free ram as I don't have to, every app starts quickly and work smooth, even though a reboot a day is needed, but it worth it as I'm using this for more than a month now, without any flashings.

A little tip that works for me on v20l is to go to Settings, Display, Display Font & choose any Font as it will ask you to restart your fone. This way, you don't have to keep doing a battery pull lol. Not to sure what rom your using but on stock 2.3.4 - you don't get the option of a reset.

On the ICS/JB selection of the fonts from the settings does not requires the restart...it takes 2seconds after selection.
So, this is not true for ICS. Applicable for GB only(maybe Froyo too)

There is a way "to increase ram". It's called swap. A program could create a swap file on your android system. Not needed files which are "on" the ram will be copied to the swap file and deleted from the ram.
Maybe this app works for you: https://play.google.com/store/apps/details?id=lv.n3o.swapper2
You should notice that a higher "swappiness" means, that the chance is higher for the data to be copied to the swap file. As you can see, it is something like a virtual ram expansion.
