Lack of available memory

I have had my X10 for about 2 weeks now and im finding that, even though i havent got many apps on the phone, advanced task killer is reporting only 30-40mb of memory available. Does anyone know why this is happening? When i first got the phone it was reporting 100+mb memory for about a week.

Android = Linux
Linux = http://www.linuxhowtos.org/System/Linux%20Memory%20Management.htm
The reason Linux uses so much memory for disk cache is because the RAM is wasted if it isn't used. Keeping the cache means that if something needs the same data again, there's a good chance it will still be in the cache in memory. Fetching the information from there is around 1,000 times quicker than getting it from the hard disk.

Do you use the advanced view of advanced task killer?
Maybe there are several system tasks running, that eat lots of memory.

i've found that since changing to RIFA016, I have slightly less available memory. (around 30MB if I remember right)

@VMaxxor: I get that i uses some of the RAM for disk caching but i had the same number of apps one week ago and i had 110ish MB of available memory. i dont how it could have cached more things.
@McKebapp: I did just enable the advanced view. the system process seem to be taking up about 100mb of memory but i hav no idea where the other 70ish mb is going.
@Niceties: What is RIFA0106?

R1FA016 is the latest build version available at the moment (correct me if I'm wrong here!)
You might have to debrand your phone to get it! (theres a thread on how to do this in this forum)

As mentioned earlier, Linux is very good at memory management and works on the principle that if memory is there and not being used for anything then it might as well fill it up with something. When you start a new app the Linux kernel organises the memory chunk it needs.
I don't use task killers, they don't really offer any benefits in a Linux based system, unlike Windows which has always been abysmal in doing this.
(BTW - The HTC keyboard rocks !!! I typed all of this fast and with the minimum of errors and corrections)

I've also realized something strange.
After restarting the Phone, I've got around 154MBs of free Memory.
I use the Pro Version of the Advanced Task Killer, that flushs the phone Memory when one locks the screen.
4-5 Days later with normal use, the Phone begins to slow down.
Then, I've just 40MBs of free Memory but no task is open.
I guess this happenes by the Linux Memory Management cashaw mentioned earlyer.
But the Phone is slow as hell.
After restarting it again --> Voilá >150MBs and the Phone is back at normal speed...

problem
this same thing happens to me....turn the phone off and it shoots right back up to 150mb or similar but after awhile it returns to 40 with no apps running and is leaving the phone really slow.

i once saw 201 mb free memory....
but soon it reduces to 130-140.
it stays there for me for as long as 2-3 days..

i just set my app killer to be slightly more aggressive and it seems to have done the trick.... sticks around 190 available now!

Available Memory, how much do you typically have?

Good day!
I've tried a few different apps now, Memory Usage, Advanced Task Killer, and I seem to hover between 110m to 25m. I kill some apps and it jumps back up to 110 and then slowly works its way back down to the mid 20's. Is this normal?
Tips? What is your available memory like?

To sum it up: Free memory is useless memory. You should have as little memory free as possible.
Explanation. Android handles memory management really well. When an app is opened and needs more memory it will shut down unused processes and free up memory on an as needed basis. For apps this can be everything from pausing individual functions all the way to saving an apps state to disk and restoring it the next time it's opened.
Task killers are mostly solutions looking for a problem, I've been running without one for months and my amount of free memory fluctuates as expected when surfing the web and things like that but so far there haven't been any times where I've had to free up memory. So don't stare yourself blind on memory meters and try freeing up memory. Android handles that well enough on its own.

+1..
The message you have entered is too short. Please lengthen your message to at least 10 characters.

That's good info! I kinda knew I was making something out of nothing with the numbers. The phone has been fine in terms of performance.

my 2 cents....i typically have between 30-60mb free. phone does not lag or anything. i used task-killer for a few days when i got phone, then actually thought about what it was doing and the way the system (linux based) is designed. i ditched it and have not looked back!
ps. my phone is rooted R2BA024 firmware, fwiw.

I usually have like 80 mb free ram just for the case and i use task manager to kill apps that are using data connection when i dont need them

I got totally obsessed with task killing but having read a lot of the lads reports on here I am on my third day of not touching it and I have to say my phone is doing fine all by itself!

I think you'd be better off setting up data synchronisation properly. I'm assuming you're talking about background syncing of course. So that you don't accidentally kill an app in the middle of a sync which might cause corruptions. I've had that happen when synching my gmail to a linux machine and the network went down, the cleanup required was insane and I lost a whole months worth of mails from the google servers.

Heh...handles memory very well, but how about the battery life!? The more apps you have- the less power you've left.

That's debatable, most background apps drain miniscule amounts of power. The exception naturally being things that makes use of the hardware while backgrounded by playing music, syncing, calculating pi or things like that. Most apps though, just hang out in memory not really doing anything. A lot of the time, if not most, it's more efficient staying there as opposed to shutting it down and starting it up again later.

+1 yes, just hanging out idle in memory wont cost you any battery, the memory will be on an base current either way, what does cost you battery is the read and write actions to memory so if you frantically clean out that memory your phone will have to write alot more to it working with your different apps resulting in a slower (less prepared) device sucking more battery then neccessary. Leave the memory handling to your device ;-)

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
http://phandroid.com/2011/06/16/android-psa-stop-using-task-killer-apps-now/

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

A weird problem

So my phone has this problem where in the settings it shows that over half the ram is free but when I see recent apps and clear them it's showing much less ram available
I dunno if it is it... Or some of my phones memory isn't being used somehow or the device doesn't recognize it.
My phone is getting slower because of this.
How do I free up most of the ram and get rid of third party apps running in the bg..
Thanks.

Restart your device daily once it may b helpful in clearing background running apps

Memory question

Why does my memory say 315 free even after I clear out all my apps in recently? I thought it would open more up.

That's your Ram.
You probably have a bunch of apps running in the background. Or one power hungry app running. Try battery pull or power cycle.
Also go look at what apps are running.

Maybe I'm confused. What should it be showing when you clear your apps in recently? I pulled the battery and it went up to 784

When you clear your apps - you free up storage space, not memory. Memory refers to the phones RAM. Don't worry too much about your memory unless your phone is lagging.

Rams going to vary from device to device.
Sometimes clearing the resent helps, but other times it may not do anything. It all depends on what the recent apps are doing.
I'm running at about 1.1 Gigs of free ram.
But I also do other things like disable certain apps and don't use all the bells and whistles of customization.
