[Q] ram - Xperia Z1 Q&A, Help & Troubleshooting

Hello guys
Am I the only one who never has more than a 1 Gb of free ram?

Android is Linux. That means free ram is wasted ram.
Stop worrying about RAM, when your phone need more then available it will kill some apps you didn't use for a while.

Best task manager for Nexus S

Just got my Nexus S 4G today and I was wondering what's the best task manager for our phone ... thanks

Theirs no need for one mate. I was fond of using a task manager on all my phones but on this beats of a device you do not need one.

OK cool thanks for the info man, I'm so use to one coming from a SGS4G

He's right, you don't need one. Especially third party ones. If you really need to kill a task or two, though, then the built in task manager will do the trick. Just a note though, killing cached tasked doesn't actually free up space (in my experience anyways).

On the Running tab you will see all running applications and services. Click the one you want to stop and then click stop.
FYI I have never had a need to do this. You're more likely to harm then good when you go killing tasks in Android 2.2 or higher.

I still thinking Advanced Task Killer is a lot simpler since it has a widget that lets me kill all wanted apps on one click.

Usually I kill apps when I feel its getting a bit slow. I do not know why but sometimes my apps use the memory leaving only 50mb left, and that makes the phone laggy and sh*t. Should it be like that? maybe I have virus?

What do you need that memory for? It is there to be used by your phone, let your phone use it. It does not cause your phone to slow down.
Memory is there so that your phone can load data from storage and get it quickly to the CPU. That is why the memory is there. Android keeps important information in memory. Then it can move it quickly to CPU when needed.
It sounds like you would prefer the phone to not use any of the memory in which case I ask why have memory at all then?
"Free memory" is wasted memory.
Sent from my Nexus S using XDA App
they are right, on 2.2 and up there is never a need for an appkiller. the way the OS is designed its able to keep all its apps in memory, that was one of the primary changes in 2.2 from 2.1. try not using it and see how it runs, just resist the compulsory need to kill apps XD
If you are using cm, you can use long back press to kill foreground app too. Enable in programs, dev

Try using a BFS kernel, it doesn't kill apps, but gives the app in the foreground more resources

You know it's hard to say. Google TELLS you you shouldn't need a task manager, and if Steve jobs told you this, would you be fuming and flaming Apple?
But seriously, the reason we shouldnt need it is because Google has a decent RAM managing system. But it's not really THAT great. What ends up happening is we play with stuff like minfree and mess with foreground memory usage and stuff. The truth is Google's memory management isn't perfect. That's why we brute force add RAM to our devices goign from 256mb in the Droid to 512mb and to 768mb in some HTC devices and now 1gb in the Atrix and SGS2.
It's pathetic because I come from the 256mb Milestone. Instead of optimizing memory use on an Android device, we have to go overboard. People keep saying task managers aren't necessary, but in Milestone development we mod the hell out of the memory management of Android.
True, task managers and autokilling shouldn't be necessary, but at the same time it won't kill your battery life UNLESS it's doing killing every 5 minutes or something. Once an hour will probably dent your battery life by 1% at most anyway.
The usefulness of task killers is often overstated, but the negatives are often overstated as well.

[Q] free memory and optimizations

Hello,
after removing alot of bloatware from the phone (LG stuff and killing some more apps & widgets)
i get roughly 163M free (after whatsapp, email, adv. task killer )
i am running on stock ROM
what are the numbers that you are getting?
i saw several people with 230M and 200 as well.
how can i get more available memory besides freeze and un-install?
It really doesn't matter, if you need more than you have free, Android will free some up for you.
yeh but i want to understand how it actually works and to remove all the rest of the bloatware from the phone.
since i still think that there are alot of things that arent required for standard operation.
Linux based OS like Android usually keep a lot of apps in memory, and if necessary free the memory for other apps, so it 's not the real problem I think.
The real issue is that some apps runs in background and use radio connection to connect to servers, to verify updates etc, and that drains battery and take CPU time. For example if you have stock firmware, and have some apps installed by your phone provider, or so.
Alternative MODS are free from those bloatwares, and even in stock ROMS if you are rooted you can use Root App Remover to uninstall stock apps that are not necessary.
You can for example try some apps like GO Launcher or Titanium Back UP to freeze the desired apps and prevent them to run in background. Make some tests o see if there is a real difference, I think most of the time it's mainly a psychological issue ;-)
Thanks a lot for the detailed explanation i have removed most of the stock apps and installed adv task manager to kill the rest but still how come people here on the forums got 230mb memory when i can only reach 180-160?

Because they use other hacks aswell ( disabling the OTA feature, using some ram reserved for the GPU as memory, etc)

I've noticed this during general use on my phone. Normally when using Twitter or Facebook.
Quite often I will go to use the app and find i've been logged out. I'm guessing the OS killed the app to free up memory for something else.
What I get annoyed with is some apps that Autostart on Bootup when there's no obvious reason why they would need to. (BBC iPlayer etc) This Just takes up memory when it doesn't need to
I've never been logged out of Twitter and/or Facebook... closing the app wouldn't log you out anyway, that's something else altogether.
I got the same issue with skype although its not supposed to logout it does even though he runs in the background
Strange right ?

Will I ever have full control of my memory???

Do you think they have any plans on changing how Android manages memory. Reason why I'm asking it's really getting annoying having keep using the task killer. Yea, yea I know that some claim that it manages memory well, but "I Think Not" the more apps you have the more memory issues you have. I can only imagine how great Android would of been having total control of how I use my memory!!
If you are rooted you have that capability.
Go to market and get Memory Optimizer for root users and it should help.
Another good one is Sysctl Config

[Q] How do I increase my free RAM?

I've seen threads where people said that their i9000 they have ~200 MB of free available RAM. That's really surprising. Can this be caused by a kernel?
I have around 100 MB of free RAM at most times, running CM10, stock kernel.
Sent from my GT-I9000 using xda premium
RAM Management is being handled by Android OS. We dont have to do anything about it. See article on AndroidCentral:
http://www.androidcentral.com/ram-what-it-how-its-used-and-why-you-shouldnt-care
So why it the free RAM memory differs so much? My i9000 has around 100MB of free RAM and other guy's from the forums has like 200MB of free RAM at any time.
It may have something to do with the quantity of apps running in every phone.
Every phone has different apps installed.
I, particularly, do not use synching, wallpapers (live or static), weather apps, music effects, google maps, etc.
I either disabled these apps or froze them to make sure they won't run.
Most of these apps run automatically at phone boot-up, thereby consuming RAM.
You can check in Settings/Apps/Running what applications are mostly running on your phone, then you can try to disable them if you think you don't need them.
How do you freeze the apps and prevent them from starting?
In settings/apps/all apps, select the app you want to disable then disable it. If you have Titanium Backup, you can use it to freeze your chosen apps.

You can use App Quanrantine to freeze the undesired apps. I use it for almost 1 year and it works.

You can increase your ram by installing devil kernel. Then installing devil kennel manager from play store
Sent from my GT-I9000 using xda app-developers app
Titanium backup or app quarantine are useful to freeze unused apps, but if you use an app you can't freeze it (or you must unfreeze it)
For used apps, you can use Autostarts to disable unwanted run of apps on phone startup, or after other events trigger in the background.
depend on the rom that you are using
Try another kernel with bigmem.
svolacius I've been red that if you have 40 20mb free memory then it is very good for you because phone is using memory properly

[Q] Cant do an actual /real Multitask

I am using Xperia SP (Indian version) C5302 Build No. 12.0.A.1.1211 Didnt update so far.
My problem is that the multitask feature is kinda like the old iPhones. When i switch apps, the previous app is terminated or loads from beginning.
For example.
I was surfing facebook from Chrome browser. I received a text. I checked my txt, replied, and when i switched back to Chrome browser the webpage started loading afresh. Is ONE webpage of Facebook too much for the "last year flagship defeater"???
While playing games,like Little Empire (online game) i was referring to online guide. So i switched to Chrome browser to see the instructions on how to defeat a boss stage. When i switched back to Little Empire the app booted from beginning. I mean wtf!! How am i supposed to refer to guides if the moment i minimize the game it switches off.
The phone has 1 GB RAM. What is the point of multitasking when apps dont really multitask. The moment u minimise its gone.
Now this doesnt happen all the time.
When i play Need For Speed Most Wanted, a game which is pretty demanding, it never closes. Even after i switch back to this game after texting , it resumes from pause menu.
Is there a way to make my phone multitask?
Some games don't work well with multitask, such as that random game you posted. Chrome is known to be ram intensive, and probably the only browser that causes launcher redraw. Use firefox instead.
If you don't like your phone, get something else...
I'm sorry bro but there's no way. The. Fact is that not our phone but android doesn't do full multitasking. Android keeps a program in memory only if the program demands it to. But even then it closes the program if another resource hogging program is loaded.

I was just wondering if converting a app into a System App might help. (And restart the phone)
For a game it is not very useful because it will be loaded at boot but for a Launcher it might help
that a third party launcher is less often redrawn. I think Android will kill non system apps first so the Launcher might stay in your ram longer.
Please correct me if I'm completely mistaken
In the free RAM 200M can not be used because the Sony locked
So always because of insufficient RAM to kill other processes
The pre allocated ram is used by debug file system, logger, camera pmem etc you can't change it unless you have custom kernel

Use "Greenify" for stop selected user app to running in background (facebook, maps...) and "Autokiller Memory Optimizer" to change minfree value (lmk). So instead to kill apps when your RAM goes under 200Mo, you can change the value to 50Mo. It's a great tool !
ROOT needed for these 2 apps
So what is the total and the free ram? By default, how much free ram is available?

Once I had the same problem with Galaxy S3 too, but I was rooted it installed busybox PRO and RAM Manager PRO, and in RAM manager I choosed hard multtiasking, and voila no more problems with redraws, and I even tried to keep opened NFS Most Wanted, and to open some more apps, and I found everything what I left,so 1GB isn't too little, it's Android memory management problem I think.
And also delete bloatware,because some sh*t is memory hungry and can cause this problem too
