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.

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 ;-)

[Q] Memory Management (Appkiller)

Hello,
Even though I am on Android 2.2 I am not satisfied by the way it handles memory allocation and management. Applications and processes I used 2-3 days ago are still there and taking precious space.
Are Appkiller applications recommended ? If yes then which one should I get.
I am a bit cautious because I have read about appkillers that on Froyo they are detrimental to the way the OS works and slows it down even more.
Any other tips and settings how I can make my phone have a lot more free memory and free space faster ?
Cheers,
MJ

No, appkillers will cause you problems, Android is actually quite good with it's memory management and all appkillers tend to do is kill off apps which the system then restarts for further info please Read, IMO I can't believe that you are running short of memory on your DHD unless you've a huge number of background tasks running

I also used a taskkiller on my DHD for some time until i figured out that it eats up the battery. (~10% / hour). I removed it and it was all good.
I think 2.2 does quite a good job in memory handling and there is no auto killing of applications necessary, except if a application freezes up and won't close or something like that.

Memory and Performance Query

I have one question again. Supposed i have a low phone memory due to so much application installed, will it affect my phone performance, coz i noticed that my phone lags with almost full apps installed in it, I wonder if low phone memory that affects the performance of my phone or bcoz of the running apps simultaneously. One thing after i uninstalled the apps from memory card it still has the folder left in it, is it safe if i remove it manually? Is that the cache? Where is the program files in the memory card where the application is so i can delete the uninstalled apps?
Thanks in advance. Lab2 guys.x0x0

having multiple apps running on your phone will slow it down because each app uses tge phones processor and RAM (random access memory) to function and at different times or circumstances they use different levels of both, leaving multiple apps running leaves tge phone without much memory to get through basic functions such as texting or playing music with ease, there is a simple, easy and free way to solve your first problem, go into your android market and look up "advanced task killer" download the free version and it will show you what is running and how much of your RAM is available and you can stop all the apps from running by just clicking "kill selected apps" and your phone will run alot smoother
as for your second issue, theres nothing to worry about, those folders just contain information the apps that you have previously installed, have downloaded, you can delete them without risk of any damage

so even tho my phone memory is full that doesnt affect the performance of my phone right. i only have 43mb left in my phone memory and its a big laggy to respond. Thanks much. x0x0

or instead using of Advance Task Killer, use Fast reboot to improve battery life. You'll be more enlighten if you visit this site [FIX] Drain Battery Fix for CyanogenMod.

You should worry about how much specific app uses your cpu not ram, less free ram = faster phone.
So try to determinate wich apps are using your cpu and kill tham.
Ignore this post if youre using eclair

Thank you guys for the sweet response. BTW it works i think the prob is my spb3d launcher that makes my phone lags.

Install System application and kill processes from there.

[Q] I wanna free my Ram a bit

how can I ?

No point
Android will free ram if needed and ram cleaners and anti-viruses often mess this up

]May i ask why you need the RAM? Its android operating system after all if program requires more RAM the system will free enough. You have 1gb free which is more than enough. If you want to free more install some ram killer/cleaner like Clean Master,or uninstall some apps that you dont use. cheers :highfive:

thanks for answers
but it's about the battery, I wanna keep the phone on as much time as I can without needing to charge it
and I thought that all these running apps are consuming the battery and reducing its lifetime

Actually, having apps in the RAM saves battery. It's more battery-consuming to have to read the apps into RAM every time you want to use them. Better have them preloaded in the RAM and always ready-to-use.
They aren't 'running' in the background, but more like 'hibernating'.
If you really want to make sure no apps are consuming data and such in the background, then use Stamina Mode. Also checking which apps are allowed to automatically sync data is one way to go.

Best ROM for performance/overclocking/gamedev?

Hi all,
I am using a T350 to test some game builds on and I am getting low frame rates because it is a few years old now
Which ROM is the most "stripped/bloatfree" version which I could use to do my tests on, And can you recommend any which have overclocking functions, and if so, what kind of stable settings have been found to work on a T350.
Thanks!

The main problem seems to be the lack of RAM, As it has 1.5GB but using JazzROM, The system uses almost 1gb of memory alone. How can I free up memory space from system processes ?

Honestly there isn't a whole lot you can do, you could maybe free up a few more MB if you go into system processes and kill some random stuff. But you're already on a custom ROM so there won't be much if anything to kill.

JazzROM is stock base ROM, that's why, it is NOT really slimmed down version. What you can do is, you can use root explorer and go to System --> Apps, and delete some apps (make sure these apps can be downloadable from either Galaxy App Store or Google Play Store)

Ok thanks guys. I set "do not run background processes" and deleted some system apps, I can get about 800mb of free memory. One other thing I wanted to ask is that when I press the power button on the device to put it in standby mode, It goes to a lock/clock screen and doesnt turn the display off using JazzROM, Any ideas?
