With 800 MB of RAM free, why do apps not stay in RAM when multitasking?

I presume that this has something to do with the min free values, but I'm not sure what to do about that or if I should modify it or what. What are your thoughts? I think apps shouldn't start being suspended until you're at least down to say 200 MB. it doesn't take long to suspend an app and push it to ram, android shouldn't be doing it so aggressively.
To test this yourself, open up a lot of apps, use the task switcher button and then scroll to the very top and select the least recently used app do this for about 10 apps, and you will see that every single one of them is pushed out of RAM and has to be reloaded, every time you get back around to it again.

Maybe it has to do with the fact that kitkat is supposed to run on devices with as little as 512mb of ram.

iive ound coming from jb that KitKat agressivly kills task or dose a better job of it jb stuff was always running in the background.

interesting. thanks. Does the other RAM go unused? Maybe it's just suspending the app not flushing to disk.

on my phone ive got a woping 1.1gb free wen all my apps are closed this is just crazy like the guy above said I think kitkat is quick to suspend apps making it easyer on devices with less ram all found that when I clear a app from recent menu that it kills it off were on jb it would still hold it in ram tell another app pushed it out.

I read somewhere that kitkat can only have 10 apps open at once. Anymore and apps are kicked out of ram. Idk if this is what is going on or what

I don't understand that thread. It's like nobody read what you were saying, just posted about how great their phone was at multitasking, or that you should use Supercharger.
Doesn't greenify kill stuff?

Probably for the same reason that Microsoft did the same when with Windows 7. Just to make the complainers feel better.

People used to cry all of the time due to Vista's prefetch doing its job. I've seen the very same thing here with 4.2.2's memory usage despite it not causing any issues.

Nah some of us read before replying. Basically until somebody makes a way to stop KitKat from killing apps when it doesn't need to us users with 2gb of ram have a lot of wasted memory. There must be a hardcoded maximum running app count in KitKat otherwise why would it be killing apps when we have so much memory left. Supercharger has a way of removing or changing that maximum so that whatever minfrees you set will let Android manage memory properly without preemptively killing apps.
Unless you have a poorly coded app that is just eating up battery when it's not a foreground application, on Android it's better to have it running in the background so it can be loaded up faster when you switch to it. Unused memory is just wasted memory.
That's the jist of Greeenify except it take sit a step further and stops that app from relaunching itself so it stays killed until you use it. Most of the time it works but some apps can be stubborn buggers.

Ram not used, but many app stay on cache, thats why new ART need more space than dalvik.

[Q] Moto G too aggressive about freeing memory - related to swappiness setting?

I have had my Moto G LTE xt1045 since they first came out and have been very happy with it except for this issue. It is very aggressive about suspending/killing apps. You notice this when you try to switch back and forth between two apps and find that it is restarting the other app instead of resuming it. It's especially noticeable when switching between a browser and another app. Another example is that I was using navigation and tried to use the NPR app to listen to some programs, but it would only do one or the other.
I realize that the phone only has 1 GB of memory, but it seems over-aggressive at freeing memory - doesn't it? I'd like to hear feedback from others about this.
In my searches for further information, it seems that one thing that can be tuned is swappiness. On my stock phone, the swappiness is set to 60. Have people experimented with different values?
My phone is not rooted yet as I've been reasonably happy with the stock experience. But I'm willing to root if it will allow a solution to this problem.
Thanks!

I was facing the same problem, I really hated that it closed the apps so aggressively. This was one of the main reasons I rooted. I don't know about swappiness, but there is a file: sys/module/lowmemorykiller/minfree which handles when the OS will kill different types of apps. If you root and download MinFreeManager you can easily edit this file. If you want more information on this topic, just search for "minfree" here on the forums. After using this app I've been happier with how memory is handled, but of course it is still only 1GB. Also it's worth mentioning that the values in the minfree file are reverted to default on boot. There are workarounds for that, event MinFreeManager has an "Apply on boot" setting, but it doesn't work for me. However it takes like 3 taps to set the values manually.
I hope I could help you.

This sounds like just what I need! What settings have you tried? Have you decided what works best on the moto G?
Thanks!

OK, I've been using MinFreeManager for a bit now and it has solved all my multitasking issues. I used this guide: Fine tuning the MinFree settings (improving on Android's multitasking) with the aggressive settings.

I confirm it works.

Just flashing the Franco kernel won't fix things?
Also the Android one phones with just 1gb memory performs a lot better at multitasking than G
Somebody with the skills should really look into how google is managing ram in that phone.
Seriously it multitasks like a dream.

No, the kernel is not the issue. It's a config file on the phone that tells android how much memory to keep free - if you follow the link in my previous post, you can read all about it and understand the issue.
It is a phone setting that Motorola changed in 4.4.4. With default settings, you will find that apps are killed by android when you switch to another app and the first app has to be restarted from scratch when you switch back to it. MinFreeManager fixes the issue - but you have to be rooted to use it. Your Android One just has less aggressive default minfree memory settings.

I see. Also one more thing I observed on Android One was that google play services was using 1/4th the ram it uses on my G . there was always 500 mb free ram

Something is killlling my ram. Rouge app? Hacker software?

I kinda frustrated and need some help. My ram is getting eaten by my phone I think it was hacked as my I know my gmail was hacked as some info was compromised. Not sure if linked to shellshock. But I know something is running on my phone as its using 70 to 80% ram I never use that!!. I terrified this is a hacker background app I have wiped to stock image twice but I'm still having issue. I even put in CyanogenMod and it's still happening. Have I been hacked? I ran all security cheetah mobile trend micro all but I can't solve this issue all says everything is ok and apps are ok.
I did use towelroot to originally route but I can't find what's eating the ram. Phone is htcone M8 unlocked with s off. Help please!!!!

yes, for android is open and many apps are using ram and space arbitrarily.
With a few simple adjustments to three settings, you can enjoy the same great speed improvements on your Android smartphone or tablet.

Setting Animations to x0.5 won't help him free up RAM, it's just an illusion that makes it LOOK like it's faster, it doesn't improve anything in real time. Also, apps like clean master etc. disrupt Androids built in task manager and can make even more problems, plus they sit in RAM as well, further taking up space. What I recommend is trying to boot into safe mode (you long press the "Power off" button on screen and then accept to boot to safe mode). The second thing you could do is trying to do a full data wipe and then flash the ROM. After that go to Settings and see how's the RAM doing. If it's full with 0 apps installed, then I'd recommend that you flash back to stock, unroot, and go to a service center.

I would look into seeing what processes are running in the background, what their CPU time and usage are, and what your RAM usage is at.
Here is a good article on the topic that might help you out.

Maybe so, but some info in it could be useful. Managing memory and tracking down rogue apps hasn't changed all that much.

[Guide] [Root] Optimize Ram and Increase Performance of Your Device

Our beloved Core Prime comes with only 1GB of ram and you know that it's a bit insufficient for our daily needs.
But I found an app which optimizes ram and thus can increases the device's performance by 25% (on stock rom) (personal opinion ).
I found it very useful specially for our device so I want to share it with you.
Here is the playstore link of the app:
RAM Manager | Memory boost
Just give it a try
This app just doesn't free ram like other apps, it optimizes it.
If you're not sure about the setting then select the 'Balance' mode as it'll do just fine for most of the users.
And one more thing. 'Busybox' is required for proper functioning of this app.

Bro kindly provide its best settings too....

Latest version of Set CPU?

Hello I'm looking for Set CPU but all links to Google Play Store appear to be broken, would like a reliable link for this app. Or is this app outdated? In that case would like suggestions for any other app for over locking of CPU. Bear in mind that I am new to the concept. Thanks in advance

Many Smart Pack kernel manager ( my favorite), FKM kernel manager , Ex Kernel manager .

This is a useless app made by Vietnamese people (I'm Vietnamese). It cannot overclock which many people mistakenly believe, and it only has the task of limiting the CPU speed, the CPU speed is managed by the OS and limiting it is a bad way because no matter what task it does it will be slowed down. When idle the CPU will automatically reduce its voltage and speed by OS. Any process no matter how big or small with high CPU speed it will be processed very fast even with small tasks that are reported not to use up CPU but it will still be faster than a slower CPU. Kernel Auditor is also useless.

SetCPU is only usefull if you have a modded kernel with added clocks (some of wich may be way to high for you device so need to be blocked to prevent crashes) and i used this version https://www.mobileapkfree.com/apk/setcpu-for-root-users IT MAY BE MODIFIED AND HAVE A VIRUS OR SOME **** so use at your own risk.
