Hi guys thanks for your time, so this is my doubt
When i turn on my phone i have 170 MB available memory but after a while down to 70 MB sometimes to 40 MB, what should i install to have more than 100 MB free?? i already have [email protected] 256Hz #97 Kernel and 2.2.1 XXJPY firmware.
thanks
regards
Usually this won't matter because with the Android OS, it will usually keep all the stuff you close (internet, contacts, recently accessed menus etc) cached in it's RAM as a non active application until you happen to tab into it again, thus instantly loading.
Android is also smart enough to know since the application is inactive, if it's eating your memory, it will force-close these applications to free up memory for the new applications. ie, I'm running internet, close it, and my memory is up to 280mb, then try to run AngryBirds and it will close the Internet app + others if it has to.
So... usually not an issue, but if it does become an issue you can run a service/task killer app that will handle all nonactive apps and terminate them. Or you can just clear level 1+2 ram periodically and it will reset it back to default until it starts filling with crap again.
Ok i have advanced task killer but i was reading in some topics in this forum that some guys have more than 150 MB free without using a task killer
Advanced task killer eats your battery
android doesn't need a task killer, as it kills tasks itself.. i don't know why there are so many out there they just eat up battery..
one app I would suggest is 'auto-killer' its free and I have mine set to aggressive. that's all you need to do then forget about it.. it keeps your memory from getting bogged down.
ok thanks for the tips
I know that android is very good at handling background processes and ram but I have so many apps that I don't use at all. They consume big amount of ram and for instance, sometimes browser loads pages again when I get back to it from another app. I assume this is because of ram. So I guess, if I can shut down some running apps in the background, available ram would be more.
I can see them at settings-apps-running(or cached processes).
For example, right now in "running" section I have 9 processes and 3 of them are poweramp, awesome beats, accuweather.com and in "cached processes" I have 10 processes and 6 of them are beautiful widgets,calendar storage,google account manager, google search, calendar, google play store. Other processes are system services that I have no problem with. When I go to developer settings-background process limit and block them, there are no cached processes anymore but that probably has a side effect. I wish I could choose which apps I want in the background.
I can shut down these apps manually but every time I restart the phone, they are there again. How can I stop them?
if you rooted, you can use Autostarts or ROM toolbox from the playstore. it can change the receivers of the apps not to start at boot

The simple answer is that you don't need to stop them!
As you say, Android is already very good at keeping track of background processes, to the extent that if a new program needs more RAM, Android itself will kill a background process that hasn't been used for a while to free up RAM for the new program.
The Cached processes screen SHOULD be full of recently used programs; it shows that Android is doing what it is supposed to do and is shifting inactive processes out of active RAM in case you want to load it again, without completely dumping the process memory.
Now, as for the side effect you mentioned, that would be a significant hit on battery life. By holding programs in RAM as it is supposed to do, the OS can load the program quickly and cleanly and more efficiently by simply reading the RAM rather than reading flash, writing to RAM, then reading from RAM. The general mantra for UNIX based systems is that unused RAM is wasted RAM.
Another thing to note is that if you do not close tabs when switching active programs (including going to homescreen) then the Browser is designed to hold that tab in memory. Even if you close the Browser (excluding closing the tab specifically with the "little x"). Even if you reboot the damn phone, it will still load the tabs/pages you had open last. The pages are not held in memory as such, just what was open and what tab order, so if you do open the browser after a while, it will load the last page from scratch.
TL;DR version: The running and the cached processes will remain exactly where they are until a new program needs more RAM than is available, at which point Android will kill something to make room. You do not need to do this manually. It will cause more power drain by making very inefficient use of RAM/Flash memory. Empty RAM is wasted RAM.
whilst Chaos is right, I notice severe performance drops when ram is filled, despite Androids theoretical advantage. It doesnt work...
Best to prevent from loading altogheter.
Root, lose warranty, backup apps, uninstall or freeze apps so the bloatware is removed.
For others, change autostart settings in Romtoolbox. So they wont start on boot.
Search for safe stuff to delete. There are lists for that

Thanks so much for detailed answers.
I got my Xperia Z1 about a month ago, and I've noticed some issues with RAM management (or possibly under-optimized third-party apps). Although I haven't had much luck in replicating the problem, I noticed it happen a few times after a Firefox internet session, or after playing a graphically intensive game like Dead Trigger 2. The app would either close by itself (not crash, as in, there were no error messages), or, after I'd close it, I'd notice my launcher (Nova Launcher Prime) go into a restart loop. A quick glance at the running apps section in settings shows 50-100 MB of free ram, and all "constantly running" apps (launcher, viber, zooper widget, k9-mail, swiftkey, tasker, etc.) stuck, for want of a better phrase, in a restarting loop (due to lack of ram I guess).
I tried running Fast Reboot (a task killer) to see if I could regain stability of the system, but it kills only a few system tasks, freeing up to a measly 50 MB of RAM, which makes me wonder (in aggravation) just where the RAM is being used. The only way the running apps would stop closing and restarting (and I need the launcher stable) is to reboot. I'm not sure if the system would stabilize after x minutes, as I only waited for a minute or two before rebooting so that I could open another app/game.
I'm not trying to start yet another debate on necessity of used RAM on Android and efficiency/futility of task managers/killers, but what I described above really seems like poor RAM management to me. I've had a few android devices in the past, and experienced various problems /errors, but never something like this.
Has anybody had a similar issue, or have any tips?
My Xperia Z1 C6903 is currently running on rooted stock 14.2.A.0.290
Although i dont get force closes, but ive noticed most of the ram is taken by the phone itself, right now for me it says i have 1.1gb in use, when i close everything i have just a slight (barely even noticeable) increase in free ram, when i click on cached processes and close all one by one ive seen it increases the ram use instead of decreasing it?
But, do you use apps like setcpu? You can keep it on performance and keep the min slider to the lowest and the max slider to max, it runs stable and gives you performance when you need it, and no performance when you dont need it.
If all fails, try deleting system apps that you barely even use or need... Becareful what you delete tho!

Thanks for the reply. No, I've used apps like that in the past, but haven't installed anything similar on the Z1, because I noticed in BetterBatteryStats that the CPU speed goes down often when the screen is off, and up when, I suppose, it's required, such as in intensive games...
What apps do you use? For example facebook, YouTube, browser etc
Ive checked again on my cached apps and to my surprise, AOSP browser takes up 208mb!
Facebook takes up 48mb, and youtube takes up 22mb.
It just depends on the apps you have installed, some use the ram even while the phone is asleep.
Ive stopped those and a huge difference was made on freeing up my ram!
What i dont get is tho why sony advertises 2.2ghz quadcore if the phone itself takes most of it?
Just delete the apps you dont need from "all apps".
Is it normal that p7 have always high ram usage? Just after boot my ram usage is always about 40% after playing 20min games like san andreas ram usage is 70% even if I close it from recent apps. At the moment when Im writing this my ram usage is 58% and I don't have any other apps running.

After I deleted all c..p from Huawei,all google services and all unwanted apk-s on my p7(untill he was working) ram usage goes extremely down.

Why is it an issue? The RAM needs to be as full as possible with apps you frequently use.
When an app needs more RAM, but it's not "available", android removes an app from the RAM you didn't used a while. It's already in sleep mode by then.
Always the same threads in the forums about RAM....they shouldn't put the RAM-available option in the phone

i would not worry about the ram usage. as this is the google 4.4.2 designed for. ( you do do a google search to find lots of info...) 4.4 version will allow max no. of apps to 'stay' in the memory, but NOT active. so next time, it saves battery power to reload them. if you do worry about ram usage, you can set up the 'protected apps' and uncheck all the apps. then when the screen is off, the apps are killed. but next time if you want to use it,it will have to be reboot again.
I have unchecked almost all apps from protected apps. I'm aware of that if app needs ram android will delete apps from recent apps, but my problem is very much like this: At the moment my ram usage is 60% without any apps running or any app in recent apps. If I open GTA san andreas It's laggy as ........ but if I open it right after reboot when ram usage is 40% it's working like a charm. Here is my ram usage after night with no apps running.

Your screenshot don't show that's your apps are closed.
Show a screenshot the tab "Active apps" under the options.
In one case I agree with you. Huawei apps takes to much RAM. My old phone Samsung Galaxy S3 had always ca 350 MB RAM free from 1GB RAM and I had more apps installed. Now with Huawei (my first Huawei), I have 2GB RAM and it's at most 800MB free RAM.
So then I compare, my Samsung used only 700 mb ram (with more apps and running apps) and Huawei take 1200MB RAM (with lesser apps).
What I saw sometimes, that's installed apps use more RAM on Huawei than on my Samsung.
My Snapdragon S10 is having a weird issue with RAM management. Over the course of a full day, basic apps like the Phone app or Textra will be closed and will need to be refreshed in memory when I open them.
I look at RAM under Device Care and there's around 5.5GB used and 1.9GB free. This is much lower than the free RAM I got on my Note 9 which usually has over 4GB free at all times.
I have Adaptive Battery disabled in the Battery settings as well. There's nothing that should be closing all my apps in the background.
Anyone else get this problem?
Think a few of my apps, like Twitter and Samsung watch app are having this issue.

I'm down to 1GB of free RAM now on a 8GB phone...
Apps opened in background right now:
Phone
Textra
Whatsapp
Kiwi Browser
Gmail
Google Photos
No games and no heavy apps. How is the free RAM so low? And in a few hours all of these apps will get closed and I'll have to reopen them.
Anyone else with this problem? How much free RAM do you currently have? And not off a fresh reboot
I have the 12gb version and have been experiencing this. It seems to clear some apps if the phone has been on staying for a couple hours.
I have the same issue. The phone becomes really slow after like 2 days of use and had RAM usage of 6.8GB. I checked in Developers settings and it says that AndroidOS and systemUI use both 5.7GB?!?! Any fix or should we report to Samsung?
I have the exynos variant and apps never close for me. Currently it's using 4.7gb out of 8gb with 14 apps open.
I checked if the apps reloaded and they didn't. Under developer settings it says that the OS is using 2.2gb, Android is using 297mb and systemui is using 246mb.
Adaptive battery is on and uptime is probably 4 or 5 days.
