why memory usage doesn't go down ?

When I use some apps on it, I understand the unit using more memory. But when I close the apps and use the task bar to close them, I still don't see a moderate reduction of memory usage.
Is there a way to free some memory when most apps are closed?
thanks,

I believe thats where programs like Memmaid come in handy, I often use it to quickly release stored memory which increases my RAM anywhere from as little as 1mb to 5mb.

are task killers a good idea?

I have been using advanced task killer free for a few days and have not noticed any difference in battery life. Shall i keep or uninstall?

same here, but its not bad, and its kill some appz and spece memory - so way not ?

google states that Android Users do not need to use task killers. Programs are left in memory for latter use, the system will even load programd you haven't used yet if the system thinks you might use it. These programs stored in memory use very little power and might actually use more because the program has to reload every time its used. I used task killers for a little. But now i don't.

Android doesn't need task killers really, if memory gets low then Android will close apps to free up memory, I find that if an app is using to much memory though...like a bad app the task killer is useful ..
To find out if an app is leaking memory you can donwload Watchtower for free to take a look whats going on..
I wouldn't uninstall it, just no need to use it so often..Android usually looks after itself..most of the time.

Task killers are actually a very bad idea. Many apps are making use of a background services, killing them as well (what most blind killers do) will result in a totally unpredictable behavior.
As a developer I really hate them. I have one app which totally depends on a background service. I get sometimes really weird error reports... questioning a little further always reveils that taskkillers have blown away the back-end of this app.

Task killers are stupid. Android has a linux base. The linux way is to cache a bunch of data into memory to allow apps to start and run faster.
How much free memory you are showing is actually meaningless because should an app require more memory the kernel will reallocate memory to the active task, automatically stripping it from idle tasks.
If you are trying to save power what its relevant is which apps are using cpu cycles. As fat as I know the only task killer type app which monitors cpu usage instead of memory usage is Watchdog.

Clean up

Does any one know if there is away to defrag the phone, or its there really no need for that?
Maybe it is better to ask what is the best way to clean up your phone

its linux man, the way they organize their files is more efficient then window. defrag only happen in window because of the way they frag their files everywhere, so short answer no you dont need to. i dont even think you need advance task killer, because i ran my phone without it and i dont see the difference when i have advance task killer

Task killers are no good. Don't use them.

No need to defrag internal storage or SD card.
Why exactly are you looking to "clean up" your phone? are you running out of storage?
If you've been moving a lot of files to/from your SD card over a long period of time and you think its getting messy, you can always format your card and start over. I do this every once and a while because I am so often flashing multiple ROMs and moving things around.
As far as task killers go, if you're running Android 2.2+, there is no need for a task killer. Task killers actually hurt your battery life MORE than letting programs run in the background or stay in memory. The simplest way to put this is that not only does the task killer have to constantly run, eating battery; but also, the programs its killing are simply restarting over and over again to get done what they need to do. I use Watchdog Lite. Look it up in the Market, in the app description it will link to the web page to explain why simply monitoring for overactive programs is more productive than blanket killing every app.
I used to be a big advocate of task killers until i realized my battery was better once I stopped using them.
hope this helped;

exist trick for high ram ?

Hi friends,
trick for increment ram free exsist? sorry my bad english
Thanks

Get yourself a task manager and kill all unnecessary processes, but I don't really know what would you use that free RAM for

ok friend,
for you the best task manager?
double thanks

Use task killer its free in the market, as for me im using System panel.

advanced task manager is the best ,but check this article out

Android system (2.2 and 2.3--> 2.1 is not too efficent in this) frees the memory itself, and caches things like Windows 7 (but in a far effective way). If you start a software that needs more RAM, then Android frees it for the app (or it tries to free it up: sometimes you have to run more than once a memory hog app to get it started), else it's precaches system things to fasten up the phone. So. If you have a lot of memory free, it's not always good.
Note that the problem starts if the CPU "can't rest". Then will come the less battery time, slowness, choppiness, etc. So: If there is an Application that has been loaded into memory, and runs in background and eating CPU cycles, then it's not good. In this case you have to close it manually. But not for the more RAM. You have to close it because Android itself MAYBE won't close it, because it recognizes as a running task (so it isn't an idle task) that is in use, and it keeps eating the CPU-->battery.
Hope this helps for the memory-geeks

possible ram problems, back to the past?

Hi
Anyone is having ram problems ?
On S2 I always have about 400 in use even with 400 apps installed the worse condition was about 200 free, but on note most of the time with less than 20 apps from market I am having about 160 free.
I fear the moment that I install all the old ones and see again the ram memory problems of first android phones and the need to get back the task killers, configure autostarts and all of that crap that I forgot with the S2.

Android is designed to fill as much memory as it can with apps, so free space generally isn't a concern at all. In fact, in theory you should only be concerned if you DO have a lot of memory free.
Tasker, however, did complain when it didn't think I had enough memory free.

The problem it isn't that android use alls, the problem it is that if you don't have enough free all the device will be slower.
why?
Becuase you have all the ram used in programs and if a new one needs more memory, like for example the browser, he will try first to delete others data and then copy her data to the ram and this will make the devices slower. Then we will have another situation, when the program can't delete others data so he can't use the ram and we will get memory notification problems and a slower device that fails to run some programs.
And 150mb free it is very little, some browsers uses about 100/150mb or games or any other apps, so I think it is a situation to be really concerned about.

I've rooted and frozen several apps from Samsung including the TouchWiz Launcher, I've installed a bunch of apps and RAM can be up to ~430mb once I've killed all tasks. I use two task killers (Process Manager & Advanced Task Manager) and I have the latter auto-kill tasks in 30 minute intervals.
But if you've installed 400+ apps, I'd think that would somewhat affect the RAM count.
