[Q] How to have more free memory

Hi guys thanks for your time, so this is my doubt
When i turn on my phone i have 170 MB available memory but after a while down to 70 MB sometimes to 40 MB, what should i install to have more than 100 MB free?? i already have [email protected] 256Hz #97 Kernel and 2.2.1 XXJPY firmware.
thanks
regards

Usually this won't matter because with the Android OS, it will usually keep all the stuff you close (internet, contacts, recently accessed menus etc) cached in it's RAM as a non active application until you happen to tab into it again, thus instantly loading.
Android is also smart enough to know since the application is inactive, if it's eating your memory, it will force-close these applications to free up memory for the new applications. ie, I'm running internet, close it, and my memory is up to 280mb, then try to run AngryBirds and it will close the Internet app + others if it has to.
So... usually not an issue, but if it does become an issue you can run a service/task killer app that will handle all nonactive apps and terminate them. Or you can just clear level 1+2 ram periodically and it will reset it back to default until it starts filling with crap again.

Ok i have advanced task killer but i was reading in some topics in this forum that some guys have more than 150 MB free without using a task killer

Advanced task killer eats your battery

android doesn't need a task killer, as it kills tasks itself.. i don't know why there are so many out there they just eat up battery..
one app I would suggest is 'auto-killer' its free and I have mine set to aggressive. that's all you need to do then forget about it.. it keeps your memory from getting bogged down.

ok thanks for the tips

[Q] Galaxy Note RAM capacity

Note Specs say 1GB RAM. My unit shows 385MB used by applications and 100 MB available. Is the rest used by the System?? How to check if my unit has really 1GB RAM installed???

Note has 1gb Ram, 200mb. reserved for GPU

OK, buT 200MB plus 385 MB used + 100MB available still do not make 1 GB!

Note have 792 available on OS, some it is user by android stock apps and services.
When I boot the phone with about 30 services and 400 apps installed I always have free about 380mb, so look the permissions to see what apps are autostarting with the boot and change them.

Please tell me how to "look permissions" and change apps at boot???

I hope you'll find answer to your questions. By the way, I'd like people to understand that free ram is UNUSED/USELESS. Our target as users and/or developers is to achieve the "enough ram for every process and app" objective. That is, we absolutely want that every bit of ram is used to make the whole system faster and readier. If you have services you need ready to be executed in ram, and you have ram for all of them, you have the best resources / results ratio. If you have 1GB of free ram and every app you need must be raised from scratch, you're not using your resources the optimal way. My 2c - maybe ot?
Good luck with your findings, anyway.

Thanks for your message. However, I read in many forum messages that too many apps in the RAM slow down the display reaction, which I found myself too.
However, I've just done the 10-second soft reset and found my RAM usage went down to 187MB used and 530MB available for services. Also found in applications management RAM capacity info: 372MB used out of 800MB. I suppose difference comes from the fact that the first capacity info relates to the space available for applications and the second used capacity includes applications AND System.
But in this case it means the Note has 800MB and not 1GB of RAM as advertised!

It has 1GB as stated. 200 MB are used by the OS. 800+200=1000.

Thanks for the message.
But why the active applications list on the bottom says 187MB used and 530MB available RAM , while the task manager/RAM management shows 372 MB used space out of 800MB??
This is what confuses me: in one place it is shown that 178MB is used and in another 372 MB used !???
Please clarify !

depends o nthe kernel you are using, but the note has 1gb of ram of whcih 800 is available for the system to use

The difference is because the active applications list in running services does not include the amount of RAM used to cache apps. You can press option key while in running services, there should be an option called "show cached processes".
If you add the amount of RAM used for both cached and running apps in running services, the total should be similar as the amount of RAM used in Samsung task manager.
This is because Android considers cached apps as free memory. They are background processes that are not visible or directly affect our use of the device and can be killed to free up memory to run service processes (i.e. user launched apps).
The cached processes basically are a list of recently used apps stores in reverse order, i.e. the least recently used app is at top of the list and most recently used app is at the bottom of the list. This way if the phone is running out of memory, it will start to kill off app at top of the list, so the app that was last used will be the last one to be killed.
The idea of cached processes is to improve the start-up time of an app the next time the user needs to run it.
P.S. I'm not an expert in Android operating system, this is just my general understanding of how Android RAM management processes.

Thank you very, very much for clarification. Now everything becomes clear and consistent !
Best regards,
Radi

When I check running applications tab insettings, I can see total RAM as 800 MB. Thanks for clarifying. I had the same doubt. But is there any way to check how much RAM is allocated to GPU using any android setting? I am keen to know this.
Many Thanks,
Nikhil Bhalwankar

[Q] Now, what is it with the free ram?

So here I am running Infinitum (AOKP) v2.1 with Devil2 0.72, 402 MB edition.
So this is the amount of free ram I have:
~20 MB. *click*
NO WAIT! its 150 MB! *click*
errr... no... its still just ~20 MB *click*
So why would android tell me I got 150 MB of free ram and 'free' command tells me something quiet different? I really don't get it, hope some1 can enlighten me :/
Thanks!

Many apps are cached/pre-buffered like in Windows, so in reality RAM is used more. This 150MB physically is not free, but it's available for apps that needs RAM - memory from this 150MB will be 'cleared' instantly.

So I am not running critically low on memory?
But I guess more ram would anyway benefit the overall performance since android could cache/pre-buffer even more, right?

You can check Memory usage with the SystemPanel app: it will list all active applications / system processes and services / cached applications , showes what amout of ram they're using and can kill the unnecesserary apps on the spot with it!

P7-L10 ram usage.

Is it normal that p7 have always high ram usage? Just after boot my ram usage is always about 40% after playing 20min games like san andreas ram usage is 70% even if I close it from recent apps. At the moment when Im writing this my ram usage is 58% and I don't have any other apps running.

After I deleted all c..p from Huawei,all google services and all unwanted apk-s on my p7(untill he was working) ram usage goes extremely down.

Why is it an issue? The RAM needs to be as full as possible with apps you frequently use.
When an app needs more RAM, but it's not "available", android removes an app from the RAM you didn't used a while. It's already in sleep mode by then.
Always the same threads in the forums about RAM....they shouldn't put the RAM-available option in the phone

i would not worry about the ram usage. as this is the google 4.4.2 designed for. ( you do do a google search to find lots of info...) 4.4 version will allow max no. of apps to 'stay' in the memory, but NOT active. so next time, it saves battery power to reload them. if you do worry about ram usage, you can set up the 'protected apps' and uncheck all the apps. then when the screen is off, the apps are killed. but next time if you want to use it,it will have to be reboot again.

I have unchecked almost all apps from protected apps. I'm aware of that if app needs ram android will delete apps from recent apps, but my problem is very much like this: At the moment my ram usage is 60% without any apps running or any app in recent apps. If I open GTA san andreas It's laggy as ........ but if I open it right after reboot when ram usage is 40% it's working like a charm. Here is my ram usage after night with no apps running.

Your screenshot don't show that's your apps are closed.
Show a screenshot the tab "Active apps" under the options.
In one case I agree with you. Huawei apps takes to much RAM. My old phone Samsung Galaxy S3 had always ca 350 MB RAM free from 1GB RAM and I had more apps installed. Now with Huawei (my first Huawei), I have 2GB RAM and it's at most 800MB free RAM.
So then I compare, my Samsung used only 700 mb ram (with more apps and running apps) and Huawei take 1200MB RAM (with lesser apps).
What I saw sometimes, that's installed apps use more RAM on Huawei than on my Samsung.

Ram usage beyond normal more than 1.6 gb

Ram usage beyond normal. Since the purchase of the phone after couple of weeks I never had more than 450 mb free. isnt this beyond normal?? plz help me to get atleast 500-700mb ram free. thank you

If your phone is rooted.. try force stopping apps that you are not using
And also try greenify or startup manager..
Keep all unnecessary background process close..

What is your maximum ram free ever?? Have you crossed 500mb over??

Yes obviously..

Yes. I was able to free 1.2gb believe or not. Besides I do lot of tweaks on its system.

I use two programs to keep my RAM usage under control on my K3 note: 1) Greenify and 2) Autokiller Memory Optimizer. Autokiller is not a task killer but a memfree setter and it works well. Both are highly recommended.

it is normal, u shouldn't worry about free ram when using linux or android.
linux = android has different concept from windows or mac os.
linux concept = unuse resources is wasteful.
tasks r purposefully left in the ram memory so that when activiting the same tasks, it eliminates reloading thus saving much needed resources n energies.
dun use autokill tasks or any free ram apps, it defeat its purpose of linux concept.
dun worry about less ram, it will automatically remove n provide additonal ram when needed.
