[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] ram running low easily

i encountered a problem that my phone always have low ram even if i just started the phone and have not open any apps. the ram always used up above 200mb out of 304mb. and y is it the overall ram is 304mb instead of 512mb which is stated in the specs of sgs

Hi,
You need to have a look at applications and services.
Check what you running (for example livewallpaper is between 11-20MB, every widget using memory as well) it is the same with services, some of them are useless some of them are not.
From my experience 2.3.3 (without any super modding) using something like 100-120MB. I can tell you that with 3 email accounts (including exchange) and some widget my SGS have free 146MB.
Is hard to say what is causing lack of memory on your phone without knowing what is on it.

I usually find that lack of ram is from apps running in the background.
I'd suggest getting TaskKiller or ZDBox to kill apps running in the background easily.

Aparently don't quote me I only ready this that the ram is on a flush when needed system I thought ram useage was high try playing game or browse net then kill them and check I found it dropped on jvk jva and now jvh not used jvb gave it a miss

[Q] RAM

Can anybody explain to me something about how the RAM works? So the phone has 512 mb of RAM, and only 330 available (I guess the OS takes the rest to 330). From those 330, around 100 are always used by something hidden. What is that?
Also if I stop some of the running services, sometimes that memory remains used.
What does eat my memory over time? I mean after some hours following a reboot my memory slowly starts to become used.
In the Running services tab there is a list of cached services and if I close any of them it eats more memory. How does that work?
I know, these questions are annoying.

128mb for tegra. that's why you have only 300mb+ for available memory

But why if I stop some processes such as the music player the RAM doesn't clear?
And why if I stop something from the Cached Processes tab it eats my RAM? (I can't find out what those cached processes are actually)

as far as i understand the system keeps it in memory in case you open something again and then it doesnt have to load everything over. and if there isnt enough for new apps it clears some ram.
this is not windows and the ram is supposed to be full. if im wrong about that someone correct me...

Yes you're right but the way Android kills processes when needed can be optimized, as sometimes the system is slow to free ram. In fact there are threshold values for different situations, that say to the system to free ram.
So the solution is not a standard task killer, but an optimization of values that triggers memory clean up. It's done for example by scripts like the one I use, see in my signature.

[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 !

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,

Ram being used

Wondering what is taking so much ram up when no applications are running is it just TouchWiz? Anyway to free up ram on stock?

I noticed the same thing however when I go to settings then application manager and see the apps that are running I noticed that it shows that I have 1gb of ram free ?

Something is up with your phone because mine only uses 1.3gb of ram with no apps running, with a bunch of apps it's like 2.3gb-2.5gb

Mine is the same as the OP...not sure what gives

Free RAM is wasted RAM.
