Hi,
I just got my S2 yesterday and I realized that if I open up task manager from a cold boot the idle RAM usage is around 300mb which seems pretty high considering I have no apps running. Even if I try clearing memory, the lowest it will go is 285mb. Is this normal or is there something wrong with my phone? How do I free up more RAM?
Android will cache apps into ram to improve performance etc.
Also the os will use some, this is normal we have 1GN of ram, don't worry about it.

Free Ram is wasted ram
Cool that makes a lot of sense. thanks for the help...

So, i've installed the 452 CH firmware with prerooted img yesterday.
I am experiencing quite "high" ram usage, with almost all applications closed via the system (not with a task killer) i have "only" 200mo ram available.
I used to have around 400 with GB.
Is it the same for everybody or do i have some bad app using all my ram ?
I've heard that ICS was better at handling cpu & ram ressources but i'm still a bit surprise by the difference between ics & gb.
This is NORMAL. Live with it.

it a Linux/Unix system... that means, the Ram is allways full - but dont care, thats give you more speed to launch some apps... and if you look nearly, mostly every process in Ram is flagt as "inactiv" or as "empty" - so if another application will need more Ram, this emty and inactive processes will be kick out of the Memory.. A full RAM dont means in a unix sys, thats no space for forground applicationd..
its also god for your CPU and Battery usage... because a Application wake up out of RAM need less CPU then boot an Aplication from the Ground... and less CPU means less batteryusage
its a Linux, not a Windows :laugh:
Okay, it's a bit like windows 7 memory management compared to win xp.
Thank you

I've got my device for one day already.
This is my first Sony Android phone and ... compared with my previous HTC old phone, Z2 is perfect.
However I find that the ram usage is terrible. There is only 1.1GB free RAM just after the device is booted up.
That means... the phone has used 1.6~7 GB RAM before I open the browser or games.
Quite ridiculous...
Is it normal? or what can I do for more free RAM
I don't think it's a problem but a good thing. Android has a smart/good RAM management. That means apps are kept in RAM until other apps need more. If you don't like you can try in developer option to play with "don't keep activities" and background process limit".
Right, you want your phone to use as much RAM as it can, this is a good thing. Also notice, the "unused" portion of RAM is also used to cache certain processes android believes you use often or will need. All of this is to speed up access to those applications as much as possible.
Take note on this
What is shown as free ram in linux is actualy freeable ram, your actual free ram is about 5mb
Linux has the motto of free ram wasted ram so when you have around 200mb freeable when your total is 3GB then there is a problem

I had Galaxy s2 with 821MB of RAM and i know that every app (not game) was eats about 20-50MB of RAM
I was sure that xperia z2 with 3GB of RAM it's more than enough but the reality is different
I see that any app in my Z2 is eats about 80-120MB! But why?
OK, maybe i know, because of tha resolution difference (in s2 800X480)
Anyone have any additional ideas for the increased RAM eating?
It uses more RAM because it can. In your S2, the OS had to ration what ram the device had between what the OS needed and what each app wanted, plus saved a bit for cached processes so overall everything would feel snappy. With 3GB of RAM, the OS has a lot more room to spread out, so it does.
Think of it like this, if your family lived in a 2 bedroom apartment, then moved into a 4 bedroom house, you wouldn't leave 2 rooms empty. Either people that didn't have a room to themselves would use them, or you would find other uses for them. Android is doing the same thing with the RAM.
You have 3GB, don't worry about how much RAM is being used, ignore it and enjoy your phone
Dont worry about ram at all, when ram is needed the kernel will free some ram up
Usualy you only actualy have 14mb free, your ram in your settings or most apps show freeable ram

I'm looking for a more accurate explanation for this fact
I'm from these users them uninstalling system apps and care to run with minimal battery drainage.
So, not received exact reason for eating the amount of memory unlike in galaxy s2

I was run with galaxy s2 on 400MB of free RAM and maybe 250 when running browser+gps+poweramp
This is not windows xp, its android and its healthy to have ram used rather than being free.
Hi, i just wonder why this phone use ram so much high? (mine: usually at 1,7GB). At first time i use this phone it was used about 1.1GB of ram.
I'm trying to compare this phone usage with my previous tablet, samsung galaxy note 10.1 and it just consume about 700MB of 2GB ram it have and at first time i use it consume about only 500MB ram.
For your information, i use almost same app running in my booth device. But..
Why it come so much different? Z2 for sure have 3GB ram (bigger than other) but i think the system at least consume much more ram too than others. Are I'am right? Can u tell me what do you think? And tell us about your idle ram usage too if u can..

I think nothing of it
Linux is healthy to use ram unlike other OSs when ever you open an app your phone will free ram if needed, its not to hard seeing as how its managed
Your actual free ram is always 15mb but freeable is usualy always %90 of your total ram, ignore how much ram is avaliable
If you want to know more, look up linux ram management

Looking at RAM usage is entirely pointless.
Apps allocated RAM as they like but the operating system makes all kinds of predictions ahead of time to preallocate blocks of RAM to increase speed, eg when an app requests to allocate some memory the OS gets to instantly go "here you go; hehe sucker I already prepared that earlier".
The OS will more or less allocate as much RAM as you throw at it up to realistic limits. Eg once a tiny app has 1gb of ram the OS will take the educated guess that will be more than enough for it and not allocate any more.
If another app opens up and the OS is running low on memory it will rejig how much it has allocated to apps that never actually requested that much memory.
This happens on any modern OS and is why you should never really care how much RAM things are using.
In Windows under process manager if you looked you would find there is about 10 different ways to look at the RAM usage per app. Unless you really know what the numbers are saying they will all means basically zero in the real world.
Woa.. I never know it before.. Thanks for the info..
Mine 1.5gb used
More then enough

How do I see this?
Skickat från min D6503 via Tapatalk
mine is usually about 1.5 to 1.9GB
keep in mind it caches apps too incase you reuse them, at the top right of the usage screen hit the menu to see the cached apps.
Mine is usually 1.5 to 1.7GB, even I don't run any app...
BTW, I install the app Clean Master ( like CC clean on Windows). And I always do clean Junk file and Boost ram once a day.
Is it good to use this app everyday?

If it's another generic 'ram booster', it's next to useless, but it won't be dangerous to use unless the app is programmed poorly. As others have pointed out, if there's no problem with the system (e.g. memory leaks), the RAM it allocates is used for caching apps so they may load quicker. Simply put, this behaviour is intended.
Cleaning junk files will probably have next to no effect on perceived performance as well untill you've hoarded enough junk files that your internal memory is almost full. But I see where you're coming from; it's very satisfying to see memory freed.
And while I am at it, I'd like to recommend SD Maid for this purpose. It's one of the few apps that actually do something useful. You can delete orphaned folders by apps that are no longer installed, delete junk and duplicate files, bulk clean app caches as well as optimise internal app databases.
Hello there,
I've been using a honor 10 for a long time now (almost since they announced and started selling it) and not once needed to check my ram usage cause it was flawless... But after 9.0 update and more seriously after last security patch my ram usage is going nuts just yesterday my free ram went down to 700mb with only SNAPCHAT running... Decided to download CPU-Z, turns out i actually dont have the said 4 gigs (4096mb) or rather 3686mb in total (note that it says 4gb in app switcher and says that i have more free memore than i really do)... Well any suggestions on how to really drop the usage? Or something else? I can feel the slowdown...
Well i can't actually post the screenshot so im gonna describe it..
CPU-Z says available ram 1317 mb (35%)free out of 3686
And phone itself 1.69gb out of 4gig....
Unused RAM is wasted RAM. The phone will free up some RAM by killing other apps if it detect app that need more RAM.
If the free RAM is low, then its possible the phone load some apps that you usually use to reduce loading speed when opening those apps.
If you feel your phone slows down after upgrading to EMUI 9, you should consider a hard reset, it might help.
For the 3,6GB RAM detection from CPUZ, I dont really care, and I dont consider it a problem.
