    Default Why does this phone use so much RAM??

    My phone constantly stays at about 1 Gb of Ram being used. It seems rediculous too me because if I had another Android phone mostly like it would only have 1gb of ram instead of 2gb. With that said I'd always be out of memory. Whats wrong with the GS3 and why does it use soo much Ram?

    Because TouchWiz is one of the most inefficient pieces of software to ever be created for a mobile platform. Unfortunately

    Better than Sense. At least we still have true multitasking.

    It may be this I'm not sure.. I use nova launcher and have no issues. I rebooted my phone last night (9pm est) and this is my ram usage now (see below)

    Are you closing apps when your done? And I don't mean by the arrow I mean holding the home button, going to task manager, and killing them from active. I always use my apps and click the home button to go to another and once I'm done I close all active apps. This seems to help with my ram usage a ton.

    Over and over I've been told. Android uses ram differently than windows. Unused ram is wasted ram. Android is supposed to use as much ram as it can to cache processes so (in theory) it will be quicker.

    I don't know how much of this I believe.

    Go to settings. Data usage. Do you have background data active? There might be the reason.

    Which is true.
    You can see this when you use the same app over and over, even if its a game.

    Go to Application Manager and click on Running tab. You can see how much memory running services is using, and how much cached processes are using.
    Mine is 747/876 MB right now.

    Using up that much memory is not ridiculous. Cached memory gets freed when the system needs it. Given that most apps on my phone are pre-cached, there will be not much freeing going on, and apps will load up faster.

    I just tried installing the nova launcher, it made no difference in the amount of ram it uses.I can't complain though phone runs just about perfect.

    Samsung was infinitely diligent to include 2Gb. You have 2Gb of RAM and you are complaining what is wrong with the GS3? Amazing. The more RAM you have on your device, the faster it is and the less battery it uses to constantly be re-opening programs. It doesn't matter that it uses 1Gb. Read and learn.

    Right. People want more RAM only to not use it? lol.

    Also...you could go into Developer Options and limit background processes, that will keep your RAM usage a lot lower (try 3 or 4).

    You are absolutely correct. It isn't Android per se, it is the underlying Linux kernel's virtual memory manager that behaves this way. And it is a good thing. :-) If you double your RAM, the VMM will fill it up eventually, and that is exactly what you want.

    Actually this is true, not just of Android, but Lynx and AIX as well. Modern O/S's keep recent apps in ram, and release them as needed (they actually watch your usage and release the least used apps first) This is also why task killers are contraindicated in Android.

    Why have all that RAM and not use it?

    Just because you're paranoid, doesn't mean they're not after you.

    Unhappy Re: Why does this phone use so much RAM??

    after updating to jelly bean i have all sorts issues. Not sure it's totally all related to the update tho.
    Can't get ram used to go below 700 with nothing running and i have only 800 something..
    most annoying and problematic is my keyboard.
    It lags horribly now and can't type to fast.
    also sometimes keys get "stuck". I had noticed this way back on hot days and my phone felt hot, that the touch screen would go haywire. now it feels that it's always in this lag state and not sure how keys can get stuck but it's like it doesn't register me lifting the finger off and need to press it again to release it. does this with stock keyboard and others.
    Not sure if it's ram related but i noticed that usage all the sudden is higher stock. Jellie bean using lots reasources?!

    The general fix for issues after the JB update is, unfortunately, to do a factory reset. The OTA update seems to cause all kinds of issues that are fixed by clearing all the data.

    As far as RAM, though, read through this thread. There's no advantage to empty RAM. It does nothing for you.

    Yeah it won't do anything. Funk (a member on this forum) has the international one with only 1GB of RAM and it sits at high usage but the system will handle it just fine. No need to worry about it.

    Flash a new rom. It's touchwiz and all of the boat ware. I'm usually at around 3 to 5 max with apps running. With stock 4.1 and touchwiz I was at 5-9.

    The processor, RAM and internal flash storage speed should already take care of speed. Utilising most of the available RAM to just keep applications and processes at hand - often applications and processes that aren't used or needed, thus the argument falling flat - especially in a device with limited battery resources, just shows that the underlying system is inefficient and has a lot of maturing to do.

    You don't understand how background apps are handled in Android, nor, apparently, how RAM uses battery.

    1) Inactive apps don't use any more battery than "unused" RAM. They're not "running," they're just bits in memory, ready to be accessed if needed.
    2) Every bit of RAM is constantly refreshed, whether it contains an active app, and inactive app, or is filled with zeros. That's simply how RAM works.
    3) Refreshing RAM uses the same amount of battery whether it's refreshing actual data, zeros, ones, or nulls.

    I have to ask you Meyer, do smartphone processors have DMA ram yet like L1, L2 caches. It'd be nice to see a processor with a 256Mb L1 and 128Mb L2.

    It would appear the S3 cpu has 2MB of L2 cache.
