Google Android & Memory Management

Hello Android Gurus
I have bought Galaxy S (My first Android phone) 2 weeks ago and i have been experimenting with it since. I have noticed one thing regarding how android manages memory and its quite alarming.
When i start my phone I typically have around 160 Mb of RAM. As i load an application that requires 10 MB for example, the available RAM evidently drops to 150 MB but when I kill the application the RAM goes up but not to the previous level (e.g. goes up to 157).
little RAM is always lost as applications are opened and closed. This means that after a couple of hours of using the phone, the RAM goes down to 40 MB and the phone becomes REALLY laggy and you have to restart
The above behavior is typical of windows mobile, and that is exactly why i shifted to Android thinking it is better.
My questions to the android experts out there are the following:
1- Why is memory leaking like this. Such a behavior results in a phone with very bad user experience
2- Is this typical behavior of Android, if yes then i'd better sell my Galaxy S and look for an alternative OS
3- Is this due to TouchWiz by Samsung, if yes then i will wait for subsequent updates to see if this problem could be resolved by Samsung
4- Will the 2.2 Froyo update resolve this issue ?
I used to have an iphone 3gs before this one, and no matter how much you open or close applications, the UI is always smooth and responsive. The thing that made me really hate Apple and its products is their "Closed OS" that does not enable you to do much with your phone. That is why i moved to Galaxy S thinking it would give me a better experience
Thanks for your thoughts.

FREE RAM IS A WASTED RAM, golden rule of android.

This is quite strange, the less RAM you have the more non-responsive the phone is and laggy.
Enough RAM has to be maintained to guarantee a smooth user experience.
If the phone requires 100Mb of RAM to run smoothly, then this much has to be maintained.
from my experience with the Galaxy S, there has to be atleaset 80 to 100 MB to maintain a somewhat smmoth interface.
Edit:
I also understand from your input that this is a Samsung problem, not an android problem, and that no matter how low the RAM is, the interface will always be smooth ??????

Mate, just one word - google.
There are about a billion articles online on android memory management, how to impoove it etc.

i dont understand how this shows anything? You are manually exiting each one of the games, forcing it to quit anyways. A better test is just to hit the home button, and continually load up the next game.

+red baloon on vid which says phone was used for >day, so "free" ram was <50MB, becouse browser etc. reserve some MBs for quick comming back.
And still was no problem to run anything I choose.

Dont quite understand..care to explain more? I'm getting puzzled abt this shortage of ram thingy. Some suggest to use task killer to free up rams while you say dont. But looking at your videos its fast..please explain. Thanks

Android handles the memory management itself. The moment it runs below certain amount of free memory it will start the kill apps. There is no need to run an app killer. Altho the default settings are not enough to provide a smooth experience. Check out the freememmanager app in the market to change the settings. As long as min 45 mb is free everything will run smooth.

This is typical Android behavior. See ya later.
Really though, if you're killing tasks, then you're already taking horrible advice from people who haven't an inkling of an idea on how Android manages memory.

Keep in mind that your phone is only using 256MB of its total 512MB of memory. Once a newer kernel is released with himem the phone will use all 512MB.
Android's garbage collection can be set to be more aggressive which would sort of fix your issue by killing more background applications. However, you might as well wait for the newer kernel which will fix your problem anyway.

Though it was more 320 out of 512

This has to do a lot with Android's garbage collector. The reason task-killers are not the best way to go, is because when you kill tasks a lot of the memory is not recovered (garbage collector does not work as it should). Android by default won't start killing apps until you get between 20-30MB of memory. For some reason, in the SGS, as you said, when ram drops below 70MB, the phone starts to feel pretty laggy; the best way to remedy this is to use applications like autokiller or minfreemanager, which require you to be rooted.
For a more in-depth explanation of how android kills processes see this http://andrs.w3pla.net/autokiller/details (from the developer of Autokiller).
I would like to know why the phone feels so laggy when ram drops below 70MB, from what I understand, this shouldn't be the case...

2- Is this typical behavior of Android, if yes then i'd better sell my Galaxy S and look for an alternative OS
--> No, this is not typical behavior of Android, i use my HTC Magic before Galaxy S, no lagging problem even the memory is lower than 15MB.

The galaxy S defaults are too low for when it starts removing apps from RAM, you need to root it and then install minfree manager or autokiller (which is not a task killer don't be deceived by the name)

doesn't solve the mystery because this is a non-issue on other android phones.
why do i need to keep 50-70mb free to get a smooth running phone where others can handle 30mb free without problems.

Goshh..thanks for simplified. Now ive removed the task killer..and stand firm by the android golden rules...cheers..

I noticed this same low ram behavior on my galaxy s. After boot the phone shows like 180 mb of ram free after a couple days the phone will drop down to 30 mb of ram all the while I'm killing apps running in the background with task killer.
The phone slows down significantly even after I kill everything.i thought android was supposed to circumvent these kind of low ram Issues.

It is.
And you're supposed to not be messing with how Android manages things cuz taskkilling screws it up.

So you suggest that I not force close any apps using taskkiller and just let android 2.1 do it's thing with memory management?
When I had the phone for the first week without taskkiller installed, the device ran very slow after the first couple days of use. Your saying that the slowness will go away as android dishes out memory effectively?
I'll uninstall taskkiller and let the device run longer than a week and see if it ever speeds up. thanks

[Q] Foce Developer Options

Hey guys,
I like to have the developer option "max background processes" set to 2. It kind of disables multitasking a bit, but it keeps like 1000mb ram available which keeps my phone nice and fast.
Only problem is, I have to re-enable this everytime I reboot my device, which isnt terrible, but its not as smooth as Id like it to be.
I also do this on my tf201.
Just wondering if theres anyway to force those settings to stay on.
Thanks,
Super

Using ram does not slow your phone down, unless it is using cpu cycles and if it is then it is either a bad app or is running still.

But as with any computing system, if you are taking up all the ram with background processes, your phone is going to run like 's***'

I haven't been able to slow down my AT&T SGS III even when I try I can't use 2gigs of ram.
In unix/linux unused ram is wasted ram. Often stuff will use *if coded properly* extra ram if there is lots of extra to use.

Ah. I see. I know that its better to have ram in use, than not too. But I was finding that I would have 300-400mb free, and my phone ran like crap. Put on the limited background processes to 2, and it ran a lot smoother.
Do you have any idea to keep that kept on after reboots?

Your issue is not your "ram" is the fact you got some ****ty apps probally taking a lot of CPU cycles.
To check what app this is *best time to check for your issue would be when your phone starts to be slow*
Hold the home button and then click task manger. From there go to Applications on the very left *probably the default place it puts you*
You can see the CPU usage on that page..
If anything is above 0% it might be what is casing the issue. If you want you can post a screenshot of that page and we can see if there are any known bad apps there.

RAM usage

I'm still pretty new to Android so I don't know what is normal, but why does the system use so much RAM when it is supposedly doing nothing? On my 2GB model, after a reboot it says that 1.2GB are free, but this soon drops to 900MB and continues to drop to 500 or 600MB, even if all apps are closed. Is this something I should just ignore and trust that tge Android system knows best and uses RAM appropriately?

Possibly, but my Memo Pad 7 seems much the same, and that's still on 4.4.2

If there is free memory then Android will let the apps sit in memory invisibly even after you have closed them - this way they will load faster next time you launch them. If the amount of free memory gets low Android will close some of those invisible apps. So that is normal, unless the amount of free RAM keeps decreasing while you do nothing with it - in that case there must be some bad memory leak.

In android, unused memory is kind of waste so system will allocate usage in a high percentage for efficiency.

It is not a memory leak. All devices which are on papers 2GB are actually less than that. Take memory for example. My Nexus says 32GB but I get around 27GB. Same goes on with USB flash drivers/ pen drives.
Secondly, On Windows, you want to keep as much RAM available as you can so that programs have enough room to operate. When RAM fills up, Windows is forced to start using hard drive space as virtual RAM and hard drives are much slower than physical RAM.
This is not true for Android.
Android’s operating system has its own native handler for assigning RAM to apps and making sure that all of it is being used in the most optimal way. In fact, Android purposely tries to keep apps loaded into RAM for better performance. RAM is fast, remember? On mobile devices, every bit of speed is critical for a good user experience, so keeping apps in RAM is actually a good thing. So regardless how much your RAM is shown, it wouldn't affect your user experience unless the apps installed in your phone are more than RAM can handle at a time which means either update your phone with more RAM or uninstall your apps that you do not use!

The OP says that the memory decreases over time. If you read my post again, i simply said as you more applications are loaded over time, the memory starts to decrease! This is what causes the memory to decrease and if you could use a bit of logic, you could have easily come to the conclusion

I must say, although most of what you say is true, having less free ram absolutely does have a negative effect on user experience. My browser tends to crash, non-intensive games face lag spikes and the general UI stutters. Is this due to Android or Asus' tweaks to Android doing a poor job at managing ram? I don't doubt that in a perfect scenario with a perfect OS, what you said holds true.

I've not had good experience with the RAM so far. My browser tabs fall out of memory more than my cheap 1GB phone. It's rather disappointing. Even just switching between 2 or 3 tabs and going back to a tab after a few seconds and it's already fallen out.

Yes as I mentioned before, if the apps which are preloaded are more than RAM can handle, you'd surely see a lag but killing background apps wouldn't be of much help either unless your RAM memory has too many preloaded apps already which is affecting performance of your phone. If you are rooted, apps like greenify / titanium can hibernate / freeze apps which take up memory and usually this helps in better user interface but again many other argue the opposite.
Are you using Asus Browser ? If yes, I'd suggest to use chrome as your default browser because Asus Browser is not only slow but also it drains a lot of battery. This has been proven extensively and even reviewed on different websites including gsmarena.
Basically Nexus provides pure Android interface which every manufacturer tweaks a bit according to their own needs. Usually this tweaking means more memory usage(Ram) by system UI. This is one reason that Samsung's touch wiz lags a lot on lower end phones but the same hardware runs smooth without touchwiz. The reason is Samsung has lots of tweaks in system UI .
Some browsers conserve memory by only keeping the tab used in memory and rest are loaded when you switch them. They aren't preloaded but usually this option is available in settings to preload pages which would use more memory.
I have preordered the device with 4gb so I'm afraid I can't compare your device with mine in this regard.
Kindly tell me which browsers are you using so I can comment further

Using Chrome. That's the whole point of having more memory, so they don't have to be reloaded when switching.
If I had 10 tabs open and switching back and forth over a long period of time, this is understandable. Not 2 or 3 tabs and switching between two tabs within 10 seconds. Defeats the entire purpose of having 2GB of RAM. The same thing happens switching between apps. Many of them fall out of memory within just a few seconds of switching back and forth. My 1GB phone does better than this. Something to do with whatever memory management Asus has set up.

I understand your frustrations and it could be Asus related buy I think this is how chrome operates generally so it's the browser in my opinion. I suggest you use dolphin browser (not mini version) because it usually preloads pages on my devices and it is fast as well but I usually use it for flash support only. I prefer opera classic (now opera) on my phone with chrome . On my tab, I use chrome only. It always works for me and it's Asus made. Tell me what you think of it after using it a bit . I like chrome for its sync support which is very simple and helpful.

Using Firefox, I read about the stock browser issues before getting the phone.
Clearing ram using the built in booster appears to help with performance, although it could be a placebo, and it's certainly less pronounced than on my previous phone with only 1GB of ram.
I have greenify'd/frozen a lot of apps, including some of the Asus bloatware. No comment on improved performance though.
Overall, I'm happy with the performance but low ram still seems to bother me, although such scenarios are rare.

I think you are more worried about RAM that is left in your memory rather than actual performance. This can happen especially if you had very high expectations from this phone. According to ASUS, this is a midrange phone on their website. Not a flagship if you are hoping!
I suggest check the performance by installing some heavy graphic games and see if it lags or not. I am sure that would be the best way to find out!
Good Luck!

The browser pages redrawing is almost certainly the lollipop memory leak. I don't have a zenfone 2 yet, but my nexus 7 had this problem up until the release of 5.1, so hopefully Asus updates to that soon.

i notice when i uninstalled clean master..my ram always on 1 gb free unlike before it stays at 650..700 free...notice my phone is even faster now

What is eating all the S6 edge memory?

My last phone, the G3, has 3 GB of RAM. The G3 runs Lollipop perfectly. The S6 edge has 3 GB of RAM and there's never any of it. I understand that there's a very aggressive low memory killer but it is ridiculous that a top of the line phone needs to reclaim my podcast app or Audible while they're playing. There should be a ton of free memory and a ton of cached apps in it but the memory is full and there is nothing cached. I've never been so frustrated with a phone. I spend a lot of time sighing at it when it does something stupid. Anyway, if anyone knows where this mysterious memory is being used, please chime in.

There are suspicions that it could be related to the touchwiz launcher, try a different launcher just for the heck of it and see how it goes.

Hi gunslingerfry,
I was just reading about this on forbes. Here is what their author says to explain the poor memory usage and how to fix it "What should happen is RAM used by apps and services is released when those apps and services are not in use. Instead it is not being released which means each new app or service has to eat into additional memory until there is no more available, at which point the slowdowns and crashes begin.
The only half solutions at present are a) to hit the ‘Close All’ button in the multitasking card menu to dismiss all apps to try and claw some memory back, or b) to reboot the device. Interestingly the latter is expected to have helped keep the issue under the radar in reviews as performance testing is always done from a fresh boot."
So it sounds like you are sort of out of luck for now, but I am sure there will be some update that fixes the issue shortly.

I'm experiencing this myself but apps that I reopen from the multitask window have to reload and I lose where I was previously.. Very annoying to say the least.

Instead it is not being released which means each new app or service has to eat into additional memory until there is no more available, at which point the slowdowns and crashes begin.
The only half solutions at present are a) to hit the ‘Close All’ button in the multitasking card menu to dismiss all apps to try and claw some memory back, or b) to reboot the device. Interestingly the latter is expected to have helped keep the issue under the radar in reviews as performance testing is always done from a fresh boot."
So it sounds like you are sort of out of luck for now, but I am sure there will be some update that fixes the issue shortly.

Goldmeyer, this doesn't explain why it's 75% utilized on boot but with no running apps (according to the smart manager app). I've tried the build.prop tweaks posted around here and there is a significant difference. Smart manager reports there are dozens of apps being pre-loaded on boot (which is normal, this is what we want!) but with the same 75% utilized. Those tweaks tended to lag the device after a couple hours, which may be a manifestation of what the Forbes article is referring to. So I guess the thing I don't get, and maybe a better understanding of what the dha/lmk values that are being tweaked would help, is what is currently allocating all that excess memory? Is TW just allocating ridiculous amounts of memory to make sure it runs smoothly? Is Android hoarding it for its own uses? And if so, how can any device with less than 3 GB of ram possibly function on Lollipop?
On a much more technical note, I understand that running 64 bit means using a little more ram. Addresses are twice the size and integers will be twice the size but that doesn't explain 2.3 GB. It shouldn't be loading the entire system partition into ram.

Memory usage

Hey,
So I've been using my Nexus 5x with much pleasure but lately it's getting impossible to switch tasks fast, because they're all closing because of memory shortage. Looking in my settings it shows me that Android OS (780mb), play services (150mb) and Android system (140mb) and System UI (90mb) together take up almost 1,2GB of the 1,8gb memory. I don;t know if this is related to me being in the preview program (and having a lot of preview images updates over the last year) or it's just that the newer Android takes up more memory.
I'm pondering stepping out of the bèta program and reflashing the stock rom, but I was wondering if any of you can shed some light if this will actually help.
Thanks!

It's part of the new method for ram management. It's normal. You'll notice those take up tons of ram even on a fresh install. Over time the more apps you install the more processes they auto start. This is what will cause those things to happen. For me I noticed for example first when the HDR processing of taking a picture would push hangouts out of memory even when I was actively talking voice, it just wasn't in the front running. Android does much like windows now in claiming lots of memory to better manage and allocate it as needed

On a fresh boot, my phone takes up 1.2GB of RAM, and quickly rises to ~1.4-1.5GB. It usually says there, as I don't use a lot of apps, so I'm not multitasking a lot. It's pretty odd compared to my other devices that use anywhere from 500-700MB of RAM for the OS, but it seems to do it's job just fine nonetheless.
Side note, since I don't have a lot of Apps, and I'm not concerned about RAM usage, I've disabled zram and ksm. Haven't noticed any difference, TBH.

On a fresh boot it loads every apps auto start process. So that doesn't change anything at all. I am not talking about apps using ram from being run. I'm talking about all the processes they have that are triggered and restart when things occur.
