What are RAMs - Sprint Samsung Galaxy S III

My RAMs seem high. Just want to know what they are and why they are so high.

Are you really asking what RAM is?

RAM = Random Access Memory
When they told you your phone comes with 2GBs of memory, they were referring to the RAM. RAM is the memory your phone uses to run things temporarily, such as apps. The more RAM you have the better usually, since you can do more things at once without bogging yourself down.
What you probably mean by your RAM being high is probably the amount of RAM you're using at any given time. If it's always high, that probably means something's running in the background using it all up.

To further add to this, you really shouldn't worry about high RAM usage as well. The only time you should worry is when your phone begins to lag heavily. Otherwise, the Android OS itself is very efficient and will usually manage your RAM closing off apps that have been cached if it requires more memory to run a new process.

Holy memory leak Batman!!

My phone had been running pretty great for 14 days now without incident (in the past I was getting reboots) but then a few days ago I started getting more and more frequent launcher restarts. I checked running apps and memory was at 120MB. I restarted and with the same exact apps/services running I had 322MB. So the question becomes where the hell did the 200MB go? Seems like a memory leak to me but have no clue what could have caused it. An update can't come soon enough for this otherwise fantastic phone.

just the way it is. I experience the same thing and i show around 130 mb of free ram all the time. I just let the phone do its thing though. I'll reboot once every 2 weeks or so. I dont think your free ram level is abnormal, i see it all the time. Yes a reboot increases it to 300 mb. But it shortly goes back down. I would ignore it.
I will notice that when i get down to around 100 mb free, i'll just go about my browsing or whatever and half hour later it corrected itself showing 190 mb free, all identical apps still running.
Its the mystery of linus. Ram is shared in ways that make it extremely difficult to tally free ram. Thats why i just ignore it. And yes i get launcher closes, along with overly aggressive task killing by the OS. I personally think its a bug google may fix.

Galaxy Nexus keeps apps in memory, it never has 'a lot of free memory' if it has been running for a while. It clears memory when an application needs it and that's it. There's no 'memory leak' of that sort in Android, but there might be something off with one of those applications that might end up hijacking so much memory.
As for launcher restarts, this has never happened to me and I'm thinking that some application, that you have running, causes this.

I don't care how much memory is free. I just can't stand the launcher restarts which are directly related to low memory because the system has to dump the launcher process from ram to make space for other processes. I've seen it on many phones. Apart from the launcher restarts the phone is fine.

I'm using Nova right now but it happens with Stock launcher too. Its definitely some app that's causing it but I have no idea what it could be.

Well without reboot most I've had my phone up is 6 days. My free memory was just over 300MB so I'd almost think it's some app you are running too because why am I not seeing any leak? Are you running Nova Prime or just the freebie?
We have had a similar thread before. OP in there was amazed that some of us had 300+mb free and he had 120. Turns out it android 4.0.1 was the culprit. Are you still stock or 4.0.1?

I'm on 4.0.2 stock. My guess is .3 and later fix the issue but I'm too lazy to wipe the phone and flash a rom. I'll have to wait, it just sucks that the update is taking so long to push

In the world of real operating systems, free memory is wasted memory. Why bother releasing memory if there's nothing to replace it with?
If you are low on memory it's a good thing in Android, because that means that many apps are pre loaded in the RAM so they can start quicker.

Everyone is forgetting that he's getting launcher closes, which i get as well.

Thank you. There's a definite memory leak. Its been a day of hard use after reboot but my memory is still at times 300mb free or more. Before I rebooted it never got higher than 120. I'm hoping the app that caused it has been fixed with all the recent updates.

Right now I have anywhere between 60MB and 100MB of RAM free and zero launcher redraws. So your phone being 'low' on ram isn't what your problem is.

What are you using to see free memory? Its reported differently in different places. Go to settings Apps and Running. What does it say there? I have 300MB but it shows 100 or less in many apps. The number in the place I told you to look is how much memory is usable for user programs since it removes the kernel and running services. THIS number for me was 120MB which means all apps only had 120MB to run that weren't services. So what does yours say?

From settings > apps > running now I have between 100 and 150.

wow. And no launcher restarts? That's interesting? What rom are you on? I'm stock 4.0.2.
Sent from my Galaxy Nexus using Tapatalk
The memory is a red herring. If your launcher is restarting frequently there's something going on, but memory may not be a part of it. Perhaps it's a misplaced pointer reference or a widget that's causing the launcher to reload to resync or maybe it really is a memory problem. Either way, focusing on the memory probably won't get you any closer to the root of the issue but uninstalling suspect apps or widgets may.

AOKP. usually if I restart I get one or two launcher redraws. But that's about it.

Yeah I think this is a 4.0.2 issue for sure. I'm hoping a new release will help.

Q How to Get More Ram

Hi,
i used to to have s2, and in that cell can free upto 550MB RAM, but in one x can't seem to get more then 300MB RAM, with same amount of applications, how i can get more ram? very few programs are running in the background and they are same as in s2
thx
if you are rooted try the supercharger v6 script, it is very useful and on the highest memory kill settings you can get up to 500mb free even more but it depends on how many apps you have installed. it kills lag and cannot possibly cause any bootlooping problems and such.

Ryan, have you tried the supercharge script yourself already? It's just whenever I try and flash the .zip in recovery my notification bar dissappears. Did this happen to you?

Agreed!!
It seemed as if I had better battery usage when my phone was supercharged though. Not as good multitasking but slightly better core performance and battery.

but low ram means slow multi-tasking and more battery drain

You have a mod called "supercharged" or "supercharger" in the rom developement section ... Download it, instal in CWM and youll get it

High RAM usage

Lately I've noticed my battery life draining fast. So when I check my RAM usage its always around 1 GB at any given time. Is something wrong here? Ive removed most bloatware apps, I have no Widgets running and maybe 5 apps I downloaded. Nor am I running any live wallpaper. Just seems like a lot of RAM for not doing much with my phone..

I'm at 1.15 right now, but you got to realize that in Android unused RAM is really just a waste. With these modern phones it will keep apps in RAM to speed up launch times, response time, etc. As long as your RAM isn't so full it lags to launch new apps you're good. Android will clear space when it's needed.

How do I free up ram on my s4?

My phone will not stop using so much ram. When I flash a new Roman it sits at about 700-800mb of ram but with my normal apps I'm seeing a constant usage of over a gigabyte of ram. And for some reason, even after I close all apps/kill, the ram doesn't free up much. I'm using greenery on most my apps, can't get battery stats to work tho so I can't see wake locks that I have.

Its normal.. Mine uses about 1.3 or 1.4 gigs, I don't really monitor it but I don't have battery issues
