Hi all i have been doin some research based on snapdragon chipsets for windows mobile. Is it true that snapdragon chipsets have better battery optimizations than standard chipsets at multitasking? My TG01 only has 65mb to work with when no apps are running (only HTC sense) if i leave a few apps open, will there be a significant difference in battery life and performance? How do you guys use your HD2 with that tons of ram, do you constantly close apps or leave them running in the background? How is your battery life?

do you not find it cumbersome having to open up the task manager everytime?
i use wktask
I have a 7" Galaxy Tab 2 and my understanding was that it has a Gig of RAM, but all my task management apps report a max of just under 700 megs of RAM. I know some is probably locked and reserved for the system but that seems like a lot... Anyone know where the rest has gone?

As you said, it's reserved for system, but if you find too much RAM used, you can click the clear memory button in task manager.
I was wondering the same thing for awhile I thought it was an issue with my tab because on stock my performance was vile compared to how I thought it should perform. Rooted it and flashed today and there is definately an improvement in my benchmarks.

That sounds about right to me. The default system on a lot of devices uses more RAM than you would think. Flashing to a custom rom will definitely help with that. I flashed mine to CM9 last night and I noticed a big difference in performance. I like it even more now.
I think this is a common thing for all things stock android... my JB (4.1.1) Galaxy Nexus phone (takju build) does the same thing... quite annoying really.
1gbyte but as i know the kernel reserves some memory for system use

What's the difference if it doesn't show you system reserved RAM, or it shows it to you, but it's always fully used?

it would be nice if they would put a notification or something to indicate this in the menu area as most will not know where their ram went & probably complain about false advertising or something.
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?

Hey folks
I bought a moto g 4g a week ago. The phone itself is good but KitKat is cleaning RAM too often. If i have opened two tabs in chrome and have Skype opened in background i still have almost 300mb of free RAM. But if i switch to home screen and back to chrome one of the tabs gets suspended and needs to reload. Sometimes Skype also gets suspended. I could never bring the moto using all of its RAM. I have always at least 200mb free ram!
What can i do?? Was jelly bean better? Why is KitKat closing apps if there still is enough RAM left?
Stock has very high minfree values, they were the same on my s3 mini, I just don't understand why the foreground app will close when you have 48 MB free... I mean, this literally translated to your phone having 48 MB less RAM... My Optimus One had a stock value of 2 MB and I never had an issue... The only way to change this is with root.
Also, because chrome runs each tab on a separate process, every time you change your tab, that goes to the background, and with our super epicly stupid minfree values, they will just close (and will reload) if you have less than 300 MB free...
Changing the browser might do the trick, Chrome is horribly stressing on my laptop cpu and very glitchy on Android, but Google made that *sort of* worth it...

Many thanks for the reply. Anyone knows if for Android L the min free value are also that high? If its lower i would just wait for it. Because i dont feel good in unlocking bootloader and loose waranty to root the device...
In fact we need a device which has at least 2G RAM to use chrome on Android.
and maybe 4.4.3 uses more RAM than 4.4.2, I had 450 free ram on 4.4.2 but only 350 on 4.4.3.
Can anyone confirm that with root and lower min RAM settings chrome can be used comfortably? Im at 4.4.3 and i have 430mb free ram
And btw how much free RAM is available in cynogenmod Rom? Or slimkat Rom?

I can confirm that it will never be used comfortably, I did that on S3 mini (cyanogenmod, so pretty much the same), and since Chrome runs every tab as a background process, and android caches processes in the same category, most of the time they get the same OOM priority as, let's say, the calculator app you back-buttoned to go back, so they get killed anyway, since android loads background processes all the time, for faster loading (this is just a stupid way to put a process priority for Chrome, bad Google).
TL;DR: Google sucks at making multitasking work when browsing the internet...(most probable case for multitasking IMO)
Also, if you have Facebook messenger, or the app, which have ALL (I really mean ALL) the possible permissions, and will expand their RAM to the limit, you will always have redraws, because they are ran as a service, and will only DECREASE (because they have tons of actual services) their RAM usage when all the background apps are closed.
TL;DR: If you have Facebook app/messenger, say goodbye to multitasking.

So moto g has not enough RAM . browsing for me has highest priority. Perhaps i ll geht a nexus 5
Hmm yes if you are looking for any sort of serious multi tasking then Moto G isn't for you. A 2 GB phone is absolutely required for that.
The Moto G is excellent for smoothly running whatever you are currently doing but your background apps and browsing tabs will be killed quickly.

No, it DOES have enough RAM, even my Optimus One had enough (420), the problem is in the Chrome tab management.
But if you can get a Nexus 5, get a Nexus 5, but a quick test with the nexus 4 and Moto G showed Moto G using much less cpu than nexus 4 for the same tasks (don't know about nexus 5, but n4 vs moto g is a freaking krait versus a low end cortex A7), so Motorola really did optimize.
Spoiler
The test was done with my cousin's N4, almost the same apps installed.

got a question, i was wondering if there is a problem with my j700M. its ram always stay at 50-80% and if its worth, i'm using a debloated deodexed rom that i got here. before i flashed the rom the same problem persists. any idea?
It's the Samsung rom.
Samsung and the touchwiz interface are notorious for being a ram hog. When the note 3 came out it had 3gb ram. Over 1.5 gb was in use by the rom. The best solution, in my opinion, is to flash a non-samsung rom when it's available. Or even a tweaked kernel.

Even if RAM always at 90% , if you don't face lags then no problem
