This is for all those people that think auto-killer is the be all and end all of android.
Auto-Killer Does:
Kill Apps to free up RAM
Auto-Killer Does NOT:
Speed up your phone
Here is why!
The way RAM works is - it temporarily stores the files needed to run an application so that the CPU can access them quicker than from ROM/SD-Card.
RAM does NOT slow down when it has more information stored within it, therefore having 20 MB of free ram or 120 MB will make NO difference to the speed of your phone.
Ironically, having more free RAM may even slow down your app loading times because:
If you wish to launch an app and you have 120 MB of free ram with no apps loaded it will have to load the app from your ROM/SD into the RAM and then access it from there.
On the other hand if you have the app already loaded into the RAM, with only 20 MB of free ram, it will load quicker because it doesn't have to check the ROM/SD first!
Therefore, having less RAM free means that more apps will load quicker. In addition to that, Android already has a built in task killer which is designed to kills apps which haven't been used in a long time when you get to a very low ram figure.

Dude, you're talking to deaf ears.
n00bs doesn't care about memory management and schedulers and such stuff... so they do what they always did on their WinMo devices...
I can only hope some listen.
what about task killer is that the same ?
LOL JK
Hmm at about 26 meg left, my phone gets buggy, and slow moving.
'I dont believe appkiller makes my phone is faster, BUT It does´nt get slow...(26meg and lower)
So Autokiller will help my phone having more ram, and the phone is running fine
About the 120 meg free ram, I agree, just use a lower setting

I love the way peoples minds work. Tricks of the mind buddy, tricks of the mind...
Sure, task killers will not speed up your phone, but they will end apps that drain your battery (i.e. facebook, etc.).
I hear what you say and understand what you mean but if that is the case can you explain to me why, after a day or so my phone slows to a crawl and clearing out the memory speeds it up again?

Buggy apps wich leaks memory?
I know technically you are right but my Hero get s laggy once the RAM gets low probably due to to many background tasks running at the same time so `freeing up memory`ie killing background tasks definitely removes the lag and speeds things up again
I have to agree with kilsally here. What you have to think its that the more tasks that is open in the background in memory or not the phone will slow down due to the amount of processors running. Just like a PC the more running the slow that gets. One way to improve this is to increase system memory. In the phones case memory is not upgradable (but would be great if it could be!).
When you end tasks using task killer, it's like ending tasks on a computer and WILL speed it back up again (as there is no/very little processors running to slow it down).
Catch my drift?
its great that theres information out there stating how task killers and android shouldnt play together, but when it comes down to it, advanced task killer pro realllllllyyyyy helps keep my phone speedy. around 20 mb is where my phone gets clammy, around 65 mb is where it grows wings. at the end of the day, if i works for you do it. if not dont. THAT'S the beauty of open source <3
Well thats not really true. Although having 20mb or 120mb RAM free itself will not speed up the phone, when using a task killer to clean up running apps you see the speed increase through the lesser toll on the CPU.
When you close and app in android it very rarely closes (the developer will have to force the phone to close the process thread - its very messy), it goes to 'sleep' this often a good thing as it makes opening the app up again much quicker. however most apps leave background processes running all eating away at a chunk of CPU. using a task killer should providing there are a fair amount of apps running to start with boost the phones performance generally

which is exactly why when i have around 20mbs of ram left, killing apps makes my phone faster. people are thinking tooooooo technical about it. its not about memory being used, but whats in the memory (app) isnt slowing things down, but the fact that that app is causing cpu strain is!
It depends what you information you want to have 'pushed' to your phone. If you require it to be 'pushed' the app must run in memory to allow this to happen. Task Killer can kill apps that you don't require 'push' information.
I thought android paused cpu threads that wernt in use?
Also, doesnt matter if you have 20MB of free ram or 2TeraByte of free ram.
I've tried with and without task killers,far less problems without, and i felt it was faster without.
this kinda smells like RAM / registry cleaners for Windows, bull**** aimed at non-technical noobies.

How does facebook drain your battery? I run the app from time to time, never changes bettery life. Also the people talking about CPU hogs - most apps go to sleep in the background and do not take up cpu to continue to run (or at least a minimal amount) - if you're running apps which have memory leaks etc then i think you should choose a different app to use instead of relying on a task killer to kill the task every time it goes wrong.

Programs that aren't in use do get 'paused' however nearly any program running needs to maintain some CPU activity to stop it from crashing, and some register services that run in the background aiding the program doing what ever it does, these often don't get stopped.
Reg cleaners on PC's are incredibly useful for older PC's, ones what have had a lot of stuff installed and un-installed, and ones with slower HDD's. Because programs don't always remove any reg entries they put in when installed the registry can become massive, with slower/older PC's that can reduce performance quite a lot because it takes longer to find the things that are required, obviously this won't be a problem on newish PC's (ones with sata or solid state, or even fairly new IDE etc) but ones with old 5400rpm IDE (old laptop drives) drives may struggle a little.

how much of free ram do you have when you kill all task? just wondering because im running like 6 widgets and i get like around 165mb ram when i kill all task. and 224mb when i restart phone.
176 killing all tasks.i used to have the my toch slide and klling all apps i used to get 299 -324

I get about 185 on virtuous. People complain about sense being a mem hog, but coming from a G1, struggling to keep 20 mb free, even having 100 mb free seems pretty luxurious.
MIUI let me have about 230 mb free at any time, but if I ignored the numbers, I actually didn't really notice any difference in performance. In fact, my average mflops and quadrant scores were still better in virtuous running the same setCPU profiles. I know that's kind of a kernel thing, but still, just goes to show that virtuous is no slouch, even if it uses a lot more memory.
Just my personal experience.

I have 233mb free running CM7 Build #11. I haven't killed all tasks though, just running as normal.

really good point.
when running normal apps (messaging, internet, settings, random ish) I have ~100, if i kill everything i get 175, but that actually doesnt help performance, because next time i open messaging, it takes a few seconds to load back up because it isn't in RAM.
I'm running virtuous and OC'd to 1.49 and it runs perfectly smooth with 100mb free. I can even keep a game like angry birds running in the background without it affecting system performance at all.
on phones that only have 20-30mb free, opening something new can cause slowdowns, but for my G2, there's no need at all to force close things that are sitting nicely in the background.
I have rooted my Asus TF, Put on the H 3.1 os, used Clemsyn Blades kernel, running very nicely. I have rooted it, and uninstalled crap like facebook, books, splashtop etc...lot of useless bloatware is out...However here is the problem........LOW MEMORY....This machine has ram of 1GB, and only 800mb shows, so almost 200 for the GI, and out of that 800, about 400mb is always used, despite using various app killers, I think we should be able to get it to about 200mb used? anyone know where so much of ram is bieng eaten
My question to you great knowledgeable friends is;
1) how to get rid of more useless apps eating memory
2) does using a different launcher reduce ram eating?
3) is it possible to achieve about 200-300mb consistent ram?
This is an awsome machine, I think more tweks we can make is super. I have a Samsung GS2, I have removed most of the stock stuff on it and set up my ownlauncher etc. It runs with amazing memory, 500mb free, and awsome graphics interface. Less nonsense.

If you haven't done so already you could use Titanium Backup to remove more stuff (including system apps) since you're rooted. I would advise caution however in case you remove the wrong thing. Perhaps someone else can post regarding which particular system apps are safe to remove, as I haven't expreimented with this myself.

He could just freeze them first and play with the tf a couple of days and if there are no problems, delete them.
Removing junk isn't a bad thing to do, but in my experience, app killers do more bad than good in android. Other than in windows, you don't need tons of free ram to run apps smoothly. Android has a great ram management that fills your ram with apps for fast access, and closes the least used/needed when another app requests more ram. So if you use an app killer, your tf will have more to do with restarting the apps you just closed and your performance will actually decrease. Google it and you'll know what I mean.

As i said before, much ram usage isn't necessarily a bad thing. It only eats performance if a running app is badly coded and doesn't give its ram free when required. Then you better kill this specific app instead of autokilling stuff. Well coded apps won't eat your performance, no matter how much ram is used.

300Mb oof ram are dedicated to Nvidia Tegra 2. For this reason you read "only" 700Mb. Maybe in near future we will able to allocate more memory than 256Mb to our Tegra 2
memory usage doesn't mean too much now if the app/programe is properly coded, when needed, android should be able to release them on the fly......
same goes to my windows 7 machine, it's got 8 gig memory but the free memory always remains under 500M because the system is using them to cache most recently used applications.
Constantly clearing memory will not help too much, and believe or not, it worsens both the performance and the battery life..
but again, android is not as robust as windows in the terms of memory management, so it's not a bad idea to occasionally take a look at the actual memory usage but just don't go too excessive...
Screwing around with app-killers is never a good idea. Are you actually experiencing issues due to insufficient RAM? I've never had an issue with RAM on my Transformer. Android is much better at handling its memory than people are, let it do its thing.
And for the record, RAM is there to be used. It's the fastest memory a device has, so the more it makes use of, the better. If something else needs more RAM, Android will flush out something that doesn't need it.
I think app-killers are one of the biggest issues with Android, in that people seem to think they're necessary. Unless you actually have some app that's misbehaving or has a memory-leak or something, you shouldn't ever really need to manage your running applications. Just leave it all alone for a while and see how you go.

not at all. The machine is fast, its very quick and loads things quickly. The only time I had problem is using logmein, it crashed and said out of memory...I was a bit perplexed. I cleared a lot on my SGS2, and it was much faster.
Let me know any ideas, otherwise, as suggested, I will see how it goes
From my previous experience with Android devices, it's nearly impossible to increase the amount of free ram. I've tried, and only found one solution that I'll talk about later.
This isn't a bad thing. Ram is not CPU usage, and ram is going to use roughly the same amount of electricity regardless.
What android does is fill up the ram with programs that you will potentially use. That way when you want to use the program, it's already loaded in memory. When you load another program into memory, say a game, it will close apps to make room for the new app.
If you really want more memory, the closest thing is a swap file or partition. I use one on my phone, and it helps a good bit. Don't know if it would help the TF101, since it already has 1GB ram.
If you are still set on more free ram, try a program like auto memory manager (there is also another program very similar, has a blue fish for a logo but I forget the name). This doesn't kill apps in memory. Instead it changes the the when android closes programs in memory based on how much free memory is available and the priority of the program. I used it before on my phone with pretty good success, but now I use a swap file instead.
Right now I don't use a swap file or memory manager on my tf101, sine it runs great without it.
Thanks for all your responses.
I think this article should explain how Android 2.x operates. Even though the article is not about Honeycomb (Android 3.x), I doubt Google has changed how it manages memory in Honeycomb.

Hello,
I have question about free RAM in stock ROM (Gingerbread) on my Motorola Defy+. I have only about 60MB free of 512MB. Is that normal? And how much MB have you free on your Motorola Defy/+? And sometimes Android is little bit laggy and I think that could be because of low free memory. And also is there some way to lock launcher to never close? Sometimes happens that launcher process exit during playing 3D games and some applications. And when I close app/game it takes so long to redraw all screens+widgets on launcher (4screens, 10widgets + 8shortcuts). Thank you so much for any reply :good:

android is linux based and linux utilizes most of the memory available, so having around 60MB free ram is not bad at all. i have 70-80 mostly on cm10, and my os is running smooth.
there are a few launchers (e.g. launcherpro) that can be locked into memory, but that does not guarantee that it wont be stopped during a high ram consuming app running (3d apps).
if you are rooted i advise you to try the v6 supercharger script, which is the best memory manager there is imo, makes your phone smoother and more lag-free.
Hi everyone. I have noticed that I don't have more than 1gb of free ram even if I close all the apps. And if I open my browser, it eats 500mb of ram. My phone became slower after few days of use, I notice constant lags. I have put most apps to sleep, and disabled some packages. But still very low on ram. Any advice please?

It is normal that your phone uses ram although 1 gb available is a bit low. Maybe factory reset the phone? If that doesn't work I would go back to where you got it from or contact samsung support
I checked and I have about 1.5 available after closing all apps and optimisation
I typically have 500-700 free on mine and experience no lag. Unix based OSes are supposed to occupy memory in order to launch things faster.

Yeah don't worry it's normal !
Some OS almost use 100% of RAM, but keep providing a perfect multitasking.
It doesn't mean that you will only have 700-900 Mo available for your multitasking, your OS will free RAM if necessary and let it to the apps. And even with 10 open apps in window mode, you will still have 700 Mo of RAM available
Thanks everyone. I have 1-1.2gb free with no active apps and now i see it's ok. Phone becomes a little slower when there are many apps open, but I believe it's also ok, nothing critical.
Why do people care how much RAM is free? I don't worry about it on my phone or laptops. I just let the devices do what they do best -- entertain me

I noticed lags and then saw that I have low free ram. On my previous leeco le max 2 I've had 1.8-2 gb free. So i thought maybe i do something wrong and more free ram will make phone faster. But looks like everything's fine.

In Android unused Ram is wasted Ram. You normally want to have about 500 free. If you're noticing that every time you open an app again it has to reload then yes it's an issue.
release ram
Hi; if you want more free ram you can reduse background process in setting/developer option
if you set background process on 2 system will process only two apps.
if your phone is slow when ram is full you can use ram booster.
Force close it! and greenify (need root) are the best ram booster.
Just uninstall applicatiions that you dont use or disable them. Pretty simple
yes more ram usage is not more battery drain, and device lag if there is no more ram or not enough available but its like if you only fill 1/4 of your fridge , your fridge won't consume more power if you put more stuff on it and it become only a problem if you want to put a big thing on it but its already full , so its only now that its useful so empty a bit the fridge to make space , but empty your fridge to put nothing on it is useless, you know what I mean?
