Can anybody explain to me something about how the RAM works? So the phone has 512 mb of RAM, and only 330 available (I guess the OS takes the rest to 330). From those 330, around 100 are always used by something hidden. What is that?
Also if I stop some of the running services, sometimes that memory remains used.
What does eat my memory over time? I mean after some hours following a reboot my memory slowly starts to become used.
In the Running services tab there is a list of cached services and if I close any of them it eats more memory. How does that work?
I know, these questions are annoying.
128mb for tegra. that's why you have only 300mb+ for available memory
But why if I stop some processes such as the music player the RAM doesn't clear?
And why if I stop something from the Cached Processes tab it eats my RAM? (I can't find out what those cached processes are actually)
as far as i understand the system keeps it in memory in case you open something again and then it doesnt have to load everything over. and if there isnt enough for new apps it clears some ram.
this is not windows and the ram is supposed to be full. if im wrong about that someone correct me...

Yes you're right but the way Android kills processes when needed can be optimized, as sometimes the system is slow to free ram. In fact there are threshold values for different situations, that say to the system to free ram.
So the solution is not a standard task killer, but an optimization of values that triggers memory clean up. It's done for example by scripts like the one I use, see in my signature.
Hey,
i want to discuss the RAM usage by apps especially on our RAZR i.
In the past few weeks i realized my phone was getting slower and slower, it's not nearly as fluent as it was once. It always kills apps when it shouldn't, WhatsApp doesn't run reliable etc (sometimes i get notifications MUCH later than i should and only after opening the app). Well, i have ~70mb RAM left.
Now comes the funny part, i don't think i use that much unnecessary apps. I don't play games, delete not used apps regulary. Easy Uninstaller shows me 96 apps (and yes, this is an unnecessary app, but it makes cleaning the phone much more comfortable - so it is allowed to stay)
So what kills the RAM?
Facebook Service - can't kill - 50mb
SRT AppGuard - to kill Facebooks GPS and Location sniffers - 25mb
Dropbox - Camera Upload - 34mb
Then there is some other stuff like WhatsApp, PowerAmp Service, Maps, which consume ~80mb in total.
Now here comes a special list:
Light Flow - 45mb
Nova Launcher - 60mb
3G Watchdog - 30mb
Lux - finally lowered auto brightness - 24mb
Smart WiFi Toggler - 27mb
SwiftKey - 63mb
Whats on that list? Basically everything i NEED to make the phone run the way it's intended to. This consumes 240mb of RAM. And those are all features that should be implemented into Android (WiFi Toggler, Lux, Light Flow) or run because the original is so bad that i can't stand it (Nova Launcher instead of stock alone because of homescreen alignment, 3G Watchdog [no prediction / clarity in stock monitor], SwiftKey).
Then there's the Moto stuff you can't deactivate:
SmartActions - 40mb
MotoCare (?) - 42mb
This is basically my RAM usage i can't get rid off. I am constantly suffering Android quitting apps when it shouldn't, even when i only switch between Opera / Chrome and Adobe Reader and stay in one app a bit too long it quits the other one. Even my old Desire HD - which had 768mb of RAM - did not do that, admittedly with a great AOKP rom.
How do you handle your RAM usage? Do you have remotely as much problems as i have to handle 1gb? I don't know what i could do to reduce my RAM usage. My new tablet, a Note 10.1, makes it feel even worse as everything runs so perfect, you just know that's the best that 4.1 will ever be. Right now, i have 700mb left. I never care about RAM usage and the best thing is, when i open an app i sometimes find out it was still running in the background, it instantly appears on the screen. The Moto needs a lot longer for it now and you feel it's an overloaded phone..
i got the same problems lol
thats why im looking for an app that kills apps that i no longer need in the moment and just restarts them when i need them (something like IOS does)
anyway some apps that you are using does not use as much ram in my phone

I guess it would be the perfect solution.. If I was rooted. I don't want to do it yet, I have to send it in because of the auxiliary port not working properly and I am only waiting for any friend to buy a new android so I could borrow his while the RAZR I is being repaired. But finally, thank you, I found a proper reason why I should root my phone. Maybe I'll try the app on my rooted note 10.1 even though I will never need it just to find out how it likes my apps.
I use an app called Fast Reboot Pro. It restarts all running apps to release memory. Doing this once a day keeps my phone slick. I recommend you try it. :thumbup:

If you don't use SmartActions then you can disable it in the app menu. Should help a tiny bit!

I just installed Fast Reboot and it really does make a lot of difference. In one click of a button everything was like I just turned the phone off and on but it all happened within a second so much more conveniant. And you don't have to be rooted for it to work either.
I'll try this for a few days then buy the pro version.

Oops. I've accumulated 150 apps (need some editing), and run smartactions on my Razr i with, to my surpise, no noticeable slow-down or difficulty swopping between apps on my phone. I'm rooted, so Android firewall disables most of then when running on mobile data (with background data also disabled) but on wi-fi at home and work they all run - 845 RAM being used at the mo - 32 processes running. WiFi off at night though, one running app puts flight mode on. I usually do a manual reboot once a week, just to give the phone a break.
You should instal Pi-Lama 0.3 Most of the Motorola's bloatware are gone together with Blur stuff.
Mh .. I will send it in in maybe 3 weeks. When i get it back fixed, i think i'll do it. What i don't get about most phones on the market is that their hardware is really great but the customized Android is just awful. I don't get it.. Admittedly the Motorola UI is not that bad, but i prefer the stock android look. I find that only Samsung does a good job in customizing their software. Every other UI is unpractical, drains the battery or looks bad (my opinion) ..
I dont know how your Note tablet performs, but my GS3 was awful price to performance, it is neck and neck with the moto razr i and the moto is faster in single-running apps environment because of its very high clock and bandwith of the cpu. However, flipboard used 89mb and touchwiz thing used more than 120mb in total so, no cheers there.
No android customization is good enough. Most of them are pretty but not good enough. What's more, the GS3 died after 3 days, and no engenieer could explain it (sorry for bad level of english), it just died...
Regarding RAM issue, moto services, all in all, use 101mb as i calculated and non-stoppable servicies such as maps location, fb location, whats app service and so on takes up as much as 220mb (a bit less, but just rounding out numbers)
My entire RAM usage is of about +-600mb of 970mb. However, i use a VPN and intra-network app for my work and that eats up another 150mb adding swype and some other things such as ftp servers i get up to 800mb used and it doesnt lag but IT DOES close apps by itself. The GS3 did it too, but its multicore could open them a bit faster when more than 2 or 3 were already running.
Stock JB...around 500-600MB free...
I'm using latest Omar Rom and greenify, about 60 apps installed. When I kill all apps I've got:
Available: 475 MB
Inactive: 175 MB
Which gives me 650MB free RAM (avail and inactive is in fact free). Unfortunately it does't mean anything. Phone is'n as fast as I would like it to be, android is amazingly ****ty optimized. My previous phone (btw Defy) have had 512MB RAM and single core CPU - and with android GB (CM7) speed was comparable - apps were smaller and less "memory hungry" than on ICS or JB.
I'm too thinking about 2GB of RAM in phone (maybe XIAOMI MI2).

I'm really curious, What exactly do you need your phone do faster than it do right now?
I never see any Android Phone run faster than my razr i, the only problem is compatibility with some apps, and lack of development.
( i had a defy too, and you really can't compare defy with razr i)

Heh, I've overclocked defy to 1300MHz, with CM and minimalist theme it worked really great
I want an android phone with constant 60FPS and instant startup of apps. Now on RazrI it takes couple seconds for Chrome to became operational - where it should be instantaneous, switching between big apps also lags from time to time.

who said razr i wont run at 60fps?
to me, chrome is fast enough but stock browser is even faster.. (new opera mobile beta is using webkit too and seems good)
funny thing that you mentioned browsers, cause razr i is by far the best smartphone in any javascript benchmark
i agree that is not optimal for games, but is a great smartphone.
Hi, so I bought mina XT890 two months ago, and currently I habe 98MB of free RAM. I have disabled a lot of Motorola apps, and I think that 98mb of free RAM is too short for a 1GB phone... I guess there is something wrong, some stuff being used underground and I can't see it. My GF has a S3 Mini, and the RAM usage is much better. She has more apps and games than I do...

Do not observe how much free RAM do you have. Just compare how this phone works. It's really Fast and reacts immediatelly even you see only 98MB free RAM. It's much more better than S3 mini.

Hey there, this problem might have been discussed before but I wasn't able to find it, so the problem is with ram usasage, I once went to the apps in settings and on the running apps I always see 250mb+ ram used by something, then I killed all the apps, but that just made a dliference of 50mb ram, It's real anoying because when I want to switch between apps it's slow and when I turn a browser back on after using aother app the page realoads which I guess wpuldn't happen with 300 mb ram, does anyone know the reason for this, I am currently running cm10.1.
Thanks!

Free RAM is useless. It just sits there sucking up power and being available in case you need it. It's pretty much a waste to have 300 MB of RAM and then only use 100 MB. Instead you should try to keep your RAM full at all times with the things you are likely to need in the near future. For example, if your phone is currently only using 20% of your RAM but already caches the browser in case you'll use it soon it will be faster to load the browser. If you decide to use the music player on the other hand the cached browser can be overwritten with the music player without requiring any additional time, so no harm is done.
Modern systems don't have "free" and "in use" RAM, they have "free" (wasted space), "in use" and "cached". You shouldn't look at the amount of free RAM but rather the amount of actually used RAM is a better indicator.
The reason you only gain 50 MB when you kill all apps is because only 50 MB will be actually in use by apps and all remaining unused space is used for caching things. If your phone is slow, this is not the cause of it. You may just have a slow phone or the ROM might be slow for some (other) reason.

yeah only 50mb is used to keep the apps running, but it probably takes up a whole lot more when using the apps, and this is a problem for me that it is slow to change between apps, and when I do change between the for example if I wanna text some one back while using a browser, once i turn the browser back on it restarts the page, and that didn't happen in my zte blade, unless I had some more apps running.
I wanna know what is using those 250+mb of ram!

see exchange service,any svn services n keep track of system usage. normally 100mb+ will be taken for ui, framework...etc.
but. eventhough u keep track of it,then slaughter it, it will come back to life n running, so i wouldnt recommend slaughtering system usage.
switching between app normally slow for full or stock rom. try find some debloated rom. it will be suitable for u if u wanna more free ram rather than liquidity.

I also observed some sluggishness after some time of usage. Sometimes the phone got totally unresponsive, not catching any push events (from buttons or screen), so that I couldn't even wake it after the screen timeout. I had to wait even few minutes before it was alive again.
Google Chrome was the most ram-eating app as far as I know.
Sometimes the best method is just restart your phone from time to time or even make a wipe - this is normal for all low-end android phones as they get sluggish after some time.
Long story short: I ended up buying a new phone with 2gb of RAM

I have the same issue
I'm using CM10.1 RC5, kernel 3.0.76-gc0a8d45 [email protected] #1
I have same symptoms pawci0 and ltkipras mentioned.
But I don't want to buy a new phone...
The lack of memory is noticeable when I run Waze or maps . It just opens for a couple of minutes and closes by itself or rather hangs the entire device.
What should I do? Go for the CM10.1 stable, try a different ROM (i.e. Slim). Change kernels?
nope, waze doesnt use that much ram, try to fix permission first n clear cache in recovery
n try to use other kernel, mine ok with multitask, rather heavy with online games n hearing mp3 n receiving whatsapp, line n we chat at da same time
n try greenify app to control app thats always running.

Just try a other rom or kernel you would be amazed how lets say a change of kernel can speed things up. The point is everyone uses their phone differently different apps and things so you need to find the rom that suits you mostly.

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.

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.

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.
