I am wondering if anyone of you feel suspicious about RAM consumption on android?
Here is an example:
Galaxy tab 2 7" listed with 1GB RAM, but when viewed with stock task manager in RAM manager section, the RAM available is not 1GB, but rather on some 687MB. Furthermore, from that 687MB there is some already used by apps. Even on newly bought device with no open apps, the amount of used RAM is around 200MB, so that leaves only approx 487MB left. Even after using task killers, there is still hundreds of MB used RAM
When I search for why the RAM is not 1GB, people answer its because its reserved by android.
When I search for why there are used RAM when there is no open apps and on newly bought device, people also answer its because its used by android.
So I would categorize the problem as "the missing RAM" and "the used RAM" and ask these question:
1. If the "missing RAM" is reserved by android, then what is using the "used RAM"?
2. If the "used RAM" is used by android, then what is causing the "missing RAM"?
Does that means android double use the RAM? or is it something else?
Please enlighten me.
Great question, and I have been wondering the same thing. :thumbup:

The problem with me is somewhat like you i found with stock rom that have alot of bloatware that i have about 680 mb after installing cm10 which do not have bloatware at all the same amount of memory is found !!!!

It's easy in the world of IT 1gb is never 1024mb its 1,000mb in most cases(You can actually see your computers harddrive where they say 500gb = 500,000MB)(but it will probably maximum 998)Why? in the factory where these are made they cannot achieve 100% "capability" And where is the missing 300mb? its reserved for the ACTUAL Android system.In the task killers you can see that there are some apps running(samsung touchwiz,system-apps(not google) Which MAINTAIN the system ,and you can also see that the google apps and some other(fb,twitter etc which needs to check the intertnet to get notification etc are running too.Now to increase the ram you can install a custom rom/kernel to remove somethings(for e.g touchwiz) to get more RAM.
Now dont take these notes to serious I'm not working in these factories,places where they do this.But this is MY theory.
Tab2 should have 1 gb ram right
Galaxy s2 should also have 1 gb ram right
So why the hell when i install cm in both ram in s2 is 827 mb and in tab2 is 687 mb it is driving me mad !!!

I do realize 1GB is not 1024MB, but at least task manager should show something around 900MB like you said.
For the Touchwiz theory, I also think that it might be the culprit of the "used RAM", but i don't think it would be that much, but that's because I'm not including google apps on that. So i think your theory might be right.
Selim already answer the "missing RAM" part, it is the same amount on custom ROM, which means they DO reserved by android. And that leads to how much is the "used RAM" part, is it more "sensible" without the bloatware running around?

There are settings (in Android we call them "minfree" settings) to tell the system how much RAM to leave free and available, but the rest is designed to fill up as fast as possible and stay that way.

For most android devices, the true available RAM is always less than the stated figure, like GT2 has only 687MB, HTC One X has 976MB even both devices has 1GB RAM
Those missing RAM are not stolen, instead they are reserved by the kernel for hardware of the devices. Don't blame anyone for this, this is crucial.

That is an interesting concept of memory management.
FYI, I'm not freaked out, just wondering where the memory goes, is it effectively used or eaten by some "rouge" apps.
Thanks anyway
However my Galaxy Tab plus with ics had about 800 mb ram in the task manager. Now (yes, my gtab plus has been stolen... grr) I have the tab 2 and I see only 687. Really strange, don't you think?

RAM HELP
can someone who has well experienced with different ROMS for tab2 7.0(p3100) help me??
i originally had ICS 4.0.4 which displayed around 680 MB ram, then upgraded it to 4.1.2 jelly bean which displayed me 770 MB RAM.
i though as custom ROMS have seldom bloatwares, atleast they should display more memory, but to my surprise i found 691 MB RAM on the latest nightly build of Cyanogenmod 10.1(jelly bean 4.2). I ve not used the AOKP jelly bean ROM due to limited internet(downloading) at my place.
as i am having a LIMITED FREE INTERNET USAGE, i am not dowloading more ROMS until some one finally helps me with the fact that
"WHICH ROM DISPLAYS MORE MEMORY FOR TAB 2 P3100??????" so that i can download it the next month or via some other network
I don't think you for it, the missing ram is the system. The tab has 1 gig to start, but whennyou fire it up, the system has to use resources. The same way a computer says it has 2 gigs, but if you check, it is lower. The reason this changes from rom to rom is because each system has its own ram management. Does this help?

Sad, but that's the truth. Only 396MB RAM!
That RAM does a decent job, if lot of apps is not installed.
Ram is 512 mb but some of it is used for graphics processing..I guess......it is a decent phone I'm currently using it with no problems

Hello Guys!!
I have a pretty strange problem with my memopad. I just deleted 3 applications, each 200 mb . After this i checked how many space i have, it was aroun 900mb. After 1 min it was only 800, and now that i didnt download anything, i was just waiting, i have 450mb free space.
Anybody knows how to fix this?
thanks,

Here in Canada , we only have access to the 1GB RAM version unfortunate. Anyone using this one have performance problems? Is it slow and lagging?
I believe the same apps are installed on both versions, so I can help you figure this out by analyzing the "running apps" memory usage on my phone (the 2GB one). Bear in mind that I'm using a dual sim variant and that my 3G data connection is enabled on the first sim and I have Whatsapp installed and running on my phone. So, here it goes:
Right now it shows that the system is using 375MB of RAM, the App 349MB and there are 1.2GB of RAM free.
So, if your usage is similar to mine, you should be left with 200MB of RAM free on your system, which, to me, equals a sluggish performance on any Android phone!
Hope That Helped!
No single lag here! I'm really excited with it,totally worth buying also no heat issue's at all.
400 MB free ram using the xt1540 1g version form koodo carrier running pure stock with some apps disabled.
Guest mode????
Do u guys have guest mode available on canadian version,guest mode not available in indian version ,i am using moto g32015 16gb/2gbversion
How much free RAM does it show on your note 5 after you install every apps and games you use? I am curious to see what the free RAM once you have the phone ready. I am considering to get note 5 from s6 and I have a high hopes for note 5 since it's got 4G ram. However, Samsung has tendency to fill ram with more of their softwares when they put extra ram. Please share your free RAM size and pictures are even better.
I'm sitting at around 700MB free. Of all the apps running in the background, Messaging is consuming the most at ~100MB.
Not getting any lag in the week I've been using the Note 5.
Android loves to use the ram that the device handles....its been this way for years now. In fact it would be weird if you didn't have RAM in use.
