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.

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.

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] Memory management

Hi Arc Users,
Do you guys encounter low memory after long period of usage? It seems like the memory does not free up after using the phone for a long time. I mainly use the phone for FB, Camera and messaging.
When the phone hits like 50+MB ram or so it starts to slow down and if it goes lower than 40MB my home screen starts to lag and the app icons take a few secs to load every time i return to home screen. I'll usually reboot the phone but its quite a pain considering the boot timing for my phone is rather long, like close to 1 min.
What are the possible solutions? I've heard that advanced task killers are unnecessary for Gingerbread. If thats the case, how do I free up more memory or have better memory management for the Arc?
Am a first time android user, appreciate any advice from you guys
Thanks!

Root is the solution. Delete apps and services which you do not use.
I haven't any problem either when free ram goes down to 30MB and i don't use a taskiller.

Just what are you doing when you run out of ram? Never did I run out of ram yet. Running ram hungry games will free up more what is needed as I experienced. When I return to homescreen, it takes a while (around 2 secs) because it will free up ram from the game, then load the homescreen launcher from start/scratch.

Same here but my Arc works fine, even with 30-40MB RAM, so it isn't a real problem.
But it would be nice from SE to make 400-450MB of the 512MB RAM available for the user.

What? That is a completely pointless excercise if you understand how ram is handled by the os.
You need to root and remove bloat, check ya settings etc to get better performance. I found letting things constantly access the network was a juice eater, I don't want fb to check every 4 seconds, I update it when I want to read it lol
I use a task manager, but only because I like to see what is running and using resources. I rarely actually kill any apps, just occasionally a few things I rarely use. Even then it fills the space with other stuff.
:edit: sorry flo95, that sounded a bit crappy, no bad attitude was intended.

I do not play games with my Arc. I just used facebook, MSN, Camera and messaging occasionally throughout the day. Medium usage.
It runs smoothly for several days but maybe after a week or two, the RAM starts to get low.

I use battery guard as a task killer. It comes with a widget where you can see the available amount of ram.
I'm happy about it. Though a lot of people say a task killer doesn't help I have no negative experience using this one... and I never go below 130 ram.
I still think it does help to close tasks that otherwise keep running in the background... But I'm new on android so I could be wrong.

Hey guys
Have you tried this script
http://forum.xda-developers.com/showthread.php?t=1111145
maybe this can help w/o having to install apps or task-killers. Should work on Xperia Arc but I don't guarantee it.

That script seems to do basically the same thing as auto memory manager.. (per my previous post..)..
PS.. I currently have mine set to aggressive.

Whats using all of our ram?

I have been trying to figure out why the Note has so little of the 3 gb of ram available at any given time. After a fresh boot, I might have 1.3 - 1.5 available, but that quickly disappears.
I have frozen all unnecessary apps with Titanium Backup, yet after launching just a few apps, I'll be down to 300 mb or so. Looking at the active applications list in task manager, the apps listed are nowhere near to adding up to over a gb of ram.
Tablet seems to be performing fine, I'd just like to know where the ram is going and why. Especially when tablets with 2 gb of ram seem to have much more free at any given time.

i am with you on this issue. would like to find out for my self as well! constantly having to clear ram.
youtube, gmail, and browers = 2.1 gb / 3 gb ...
what the heck?
i constantly have to go back and clear apps, this is such a let down because my htc one could load much more than this, and every1 knows, htc one is no where near the spec of note 2014..

I'm not rooted but I noticed the same thing with the ram, I thought rooting and freezing some Samsung apps, specially Knox stuff, would free up a lot of ram. I'm starting to think that it's not a big deal and Android frees up ram as needed before it starts to get laggy (of course it's not perfect). I think lag issues are somewhere else and not so much in freeing up more ram. Don't you feel anyway that your note is a lot faster after rooting and freezing those apps? As far as I know most rooted users feel that way...(?)

I have rooted mine about two weeks ago then froze all sort of junk listed in here and some other I identified mysefl. Now my used ram remains around 500 clean and around 700-800 when I open few apps. So guys the secret is getting a lot of useless apps frozen especially knox stuff.

Android is based on Linux. Android and Linux both run better when they use as much ram as possible. If you Google Android ram usage you can find a couple of interesting articles about this.

Yup, stuff is kept in the RAM as much as possible to increase performance. As soon as an app requires more RAM than is available, the system moves apps from the RAM as required. Clearing the RAM only increases the time it takes to start an app next time.

People are used to Windows needing free ram and do realize that Linux is a completely different animal altogether.
Here is the article for those that want to understand the ram usage.

Okay, guys. Disclaimer: I'm an IT professional and the Mobility expert for my company. I know how the RAM is used and why. I'm just curious as to what is using it. Especially in comparison to the Nexus 10, which has 2/3 of the RAM and has approximately the same amount available at any given time.
I wasn't looking for assurance that this is how it's supposed to work. I'm curious as to what you guys think is actually filling it up. Since I have disabled most unnecessary processes and only run a few apps at any given time, I can't see why so little is free.

The objective of good android RAM management is to keep RAM full of the the highest priority apps. This enables faster and smoother response. The apps that are in RAM on your device will be different than on someone else's device. If you are curious about how android decides what put in RAM and what to take out, do a google search on "android process lifecycle"

if you're concerned about ram usage go to dev settings and change the "Limit background processes" to something more you liking.

[Q] RAM is at 2GB of 3GB ??

I have noticed that im using up 2gb of ram. But i have only downloaded a few apps. No games. All the stuff i had before. My old phone was a little over 1gb total. Is this normal. Does the phone uses a lot of ram out of the box. Im thinking of rooting just so i can free up some ram. Not sure if that is possible. Im coming from a galaxy and very happy with this d851 g3.
Anyone having a memory problem ? Issues? What can i do?

Android always runs while using up as much ram as possible. Thats normal, if your phone had 8gb of ram, most likely it would also be using most of it up.

Makes app switching faster.......

All that bloatware runs in the background contributing to a high ram usage

Not completely true. I disabled most of the T-Mobile and LG crap on this phone and it's still using the same amount of RAM. It's Android's memory management.

I bet if the Android team could go back in time in the early days of system development they would have probably removed the ability to see free ram. So many people get caught up in free ram when the phone is using the available ram to the best of its ability.

Windows does alot of the same as well. Even though if you go into task manager it shows free if you actually look at your system resourses it shows alot of it is taken.

Unused RAM is wasted RAM.

Not sure about the whole 2g for 3gb thing but your system need all the rams it can use to keep your phone running smoothly. If you use ram cleaner (so they are call) you will notice your phone goes through a gitter before it it can pick up again. You look 5 minute later, its like you never clean anything.
and tmobile is surely 3g

Free RAM is wasted RAM.

Android uses RAM differently from say Windows. Android will use as much ram as available and when it needs more, it will free it up as needed. This is normal.

So yea i installed greenify and it made a **** load of a difference because i have like 40 games and a load of other apps. I have less than 1.5 gigs used now. And my phones way smoother and batterylife is good again

Don't worry you're about to see that battery life drop like a rock. Constantly killing apps will kill your battery fast. Greenify is a nice app if you have a crap phone but your G3 was made the way it is for a reason. What you think is smooth and fast is actually hurting your phone. Don't believe me, Google it and do some research. I do not recommend anyone using any format of task killer or ram optimizer on a phone that is current with the times.

Do I think the phone has issues. yes. When using it the apps don't close when ram is needed. Only fix is a reboot or kill the app but at times that does not work

Don't worry Jammol doesn't know what he is talking about. Greenify doesn't hurt battery life and performance like a task killer because isn't a task killer. It is completely different. I agree that task killers should be renamed to battery/phone performance killers but Greenify is very different.
First of all it requires your phone to be rooted. Assuming that it is, it uses special permissions from the rooted device to essentially freeze the app unless it is opened by the user. For example, I use facebook but only casually. I look at it once every other day or so but have noticed that the push notifications and messenger uses a lot of battery because it does a partial wake everytime it pushes a update which activates the internet and cpu.
The solution is to "Greenify" the app. The app still loads normally when I open it up although, because it is not in the ram, it likely takes slightly longer to load. Once it is opened, I can use it like normal and I get push notifications again until my phone's screen goes off. Once the screen goes off, facebook and all the apps that I "Greenify" are flushed from the memory and are banned/essentially frozen until I launch the respective app again. The only drawback to this is that you essentially never get push notifications for the apps but it saves a lot of battery if you pick the apps that you don't care much about/rarely use.
So greenify does work really well. Today my phone had 17% left. I it had 16+ hours of battery time total. I got 4.25 hours of SOT with sync on (with 3 email accounts getting push notifications plus other apps), GPS high accuracy, LG health automatically recording my exercise, and 1 hour of navigation with Waze. Basically I used my phone how I wanted and didn't micromanage my battery usage throughout the day at all.
I used 3 battery saving tools. 1. ART 2. Greenify and 3. Custom Kernel V002 from KAsp3rd. These three are very powerful together.
I hope that helps someone!

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!

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.

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

Sometimes it's good to swallow some pride and in that there's more dignity. I explained everything from bits and pieces and I'm sure OP can conclude it unlike you.
Do not hesitate to quote me for any query. Always welcomed

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.

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

Correct, thank you for finally making that point clear as it's the main reason, which clearly isn't Asus' fault.

An ironic, yet awesome find pato!:thumbup: Be sure to relay this to the other places on the net that you're involved with that pertains to the Zenfone 2.
