I have the Advanced Task Killer app for my phone (new android user lol) and with autokill set to "Crazy" on screen-off.
so most of the time I'll have ~200mb free ram. makes me feel good with big numbers.
but as i run more applications(settings/whatever), more com services start to run. i'm just wondering if there's a list somewhere (searched the net numerous times) about safe com-services to kill.
all in all... how much free ram do you have on average before/after kills?
I always have 90-110M ram
I've got AutoKiller set to aggressive, leaves me with about 100mb free. More than enough, imo.
I read somewhere that using task managers to kill apps ends them in an... improper way? Might want to look into AutoKiller instead ;o

quite right, they interfere with androids memory management and can in fact actually cause slowdowns. Android like most modern operating systems have pretty good memory management and things that try and take that role over usually just end up causing issues.
I was using aggressive but have moved to strict and find that just as good, the lower you can go the better really.
Free memory is really wasted memory in modern OS's.
If the device constantly has 60MB free ram, i dont really see the real benefit of it having 200MB of ram.. i mean i expect it to perform the same since it is not running out of ram yet.

Trouble is, if you go too low on this device it becomes very laggy. As I type this I am down to 42mb and the thing is a dog!

What makes me wonder if you let Android do everything on its own (eg. not close applications until more ram is needed), isn't the CPU used a lot more? Some programs aren't just on standby when not used afaik.
I reckon you're doing exactly the opposite. See, unless the app has service like functions it's unlikely to be using any clock cycles when onPause or onStop functions has been called.
On the other hand, if you simply kill an app the entire process of loading parts of app into RAM will have to be executed again, should you decide to start the app up again.

If the app does have services running which are doing things like maintaining a database, syncing with servers, etc. then force closing these background tasks may corrupt databases and cause other problems. The services are probably set up to auto start as well, so they will just come right back and use up battery+cpu reinitializing.
Also, you don't need 200mb of ram free when your phone isn't doing anything. If you do launch something that needs 200mb of ram, then your phone will kill off everything it needs (in this order-> apps without any windows, background windows, background services).
Also, most people will use the same apps (email, phone, etc) throughout the day, and only occasionally launch new apps. If you follow this usage, and you use a task killer, then every time you go into email, the email application has to fully restart which costs you battery, disk acces, etc.
hmm true. i guess i'm just ram hungry. i get about 150~ on average though. i should probably go back to autokiller and put it on a lower threshold.
but damn, my phone drains 30% overnight? it's appalling, anyone has that issue?

You possibly have something on a high refresh interval, which is waking the phone throughout the night to sync. I was having this problem when I frist installed twitter as it ended up on a 15min refresh. I now have everything on the same refresh cycle, 3hrs I think, and now the phone is pretty much fully charged still in the morning.
impossible, I've for every syncs I know set to off. but I've flashed samset and all that good stuff so I shall monitor over the days!
My average is about 150 too , some times even 200
I have never seen 200MB of free MB. About 150 is the maximum I can get up to right now.
Still, why does the android OS use up so much RAM?

Because it can.
Aslong as there's enough free ram (determined by values alterable with AutoKiller) Android won't close applications/services for the simple reason that "Free RAM is wasted RAM". The only "benefit" of having tons of free RAM is epeen factor and possibly sometimes if you happen to load up a very RAM heavy game.
Note the "possibly sometimes"

My most often available RAM if I leave things untouched and see 20+ programs running is about 80mb. If/when I am using ATK (I use manual mode), I see about 150, but 50+ goes into my UI combo (LauncherPro + Quickdesk + WidgetLocker + Widgets)

Two biggest things that kill my battery when I'm not "using" the device is sync and ATK. Do not use ATK at night, no matter what, it's essentially wasted. IMO, for typical users there is also more costs associated with autosync during the night than benefits (cost = battery life, and a tiny bit of bandwidth... benefit = having the info available when you turn ur screen on rather than waiting less than 5 mins to get said info).
What ATK essentially does is take the phone out of an idle mode, run the processor to clear up memory. Then, Android does it's thing and opens more programs, recreating the need and a vicious cycle of close-open-close-open where you are using processor that is completely unnecessary. It sounds like you already have your answers and solution from this thread, but I'm just here to reaffirm your belief.
I'm also a bit of a RAM queen, but I only use ATK in the following two scenarios:
1) I'm about to do some heavy tasks (usually gaming, sometimes a GPS tracking)
2) I've just synced and updated to the marketplace (everything under the sun has launched and I just want to see them closed.
In both of these scenarios I actually kill ATK as well, I open it back up and see about 180mb of free RAM (and as I've said, I have about 50mb dedicated to my custom UI).
- Unrooted SHW-m110s, Korean, Galaxy S (waiting for FroYo).

I'm curious if this helps you at all - if I run ATK to kill tasks before starting a game, the game launches maybe 1-2 seconds quicker, but actually running ATK to kill the tasks takes 5+ seconds. Once I'm inside a game/benchmark, my fps seems to be identical.
Do you see the same thing? If so, why do you use ATK?

Sure you're not looking at total RAM available? 'Cause that's the number I see when I go into Samsung's Task Manager (X/326MB).
Also jg9? I must've missed something
Hey guys, what's normal ram usage for you?
Cause to me, what I'm getting seems higher than it should be.
I'm seeing well in excess of a gigabytes used when I'm not doing anything on it, even after I first restart, there's around a gig used. I removed apps I don't use, I'm running the latest release of PACrom, here's a screenshot I just took.
http://imgur.com/w5KGKJF
Also battery usage always seems high, could that be related possibly?

1.3Gig is usually normal for touchwiz but for AOSP not try changing the Rom and see as for the battery check what apps are draining it
Yeah, that's normal.Mine is using 1 gib and I don't have any apps running.

My run is AOSP based, and according to the settings, the screen uses most of it.
But I rarely have the brightness up high, and often battery widget says I'm using in excess of 1300mah D:
Sent from my GT-I9505 using xda premium
I'm using stock ROM with Deodexed and Zipaligned apps, My RAM is 0.8GB when no apps is opened, and it goes to 1GB when few apps are opened
That is NOT NORMAL AT ALL... Using aosp based Roms like pacman and slim bean I have an average of 400mb used and like 1.4 free... I don't think I've ever passed 800mb running an aosp ROM or any ROM for a matter a fact... Check to male sure it doesn't count cached apps cause that takes up around a gig sometimes...
..... its normal if you have some widget running....

There is no reason to care about ram usage on a Linux system.
In Linux, unused ram is wasted ram.
Using all your ram doesn't mean no more ram is available. It means that the system is storing everything its done recently in ram so its more quickly accessed if you try to use it again. If your ram is full and you need to do something else the system will effectively and efficiently push the lowest priority task out of ram to free up more for the new task.
Using all your ram does NOT slow the system down. It is not like Windows where freeing up ram makes everything run faster.
All this monitoring ram is pointless in a Linux based OS.

I fully agree with your clear explanations but in my case when I reach low memory level like 100 Mg the camera doesn't fully start (black window).
I am forced to reboot or clean as well.
I feel something is weird in this phone memory managment. (GT9500 model for me)

Best answer ive seen c:
This takes me to my other question of could this be affecting battery life ?
Ive had the battery go from 100% down to 85% in a space of 20 minutes, with brightness on auto, and only using one app (LINE) :c
I remembered seeing other peoples comments on using only a few hundred meg of ram, and also seeing compliments on the battery life of the rom (PACrom) around those same posts, So im trying to figure out how to prolong my battery life as its pretty important to me, I dont really get a chance to charge throughout the day D:

Can anyone of you download advance task killer from the android market/Google Play. Download and could you check how many memory do you have? When I bought my note, I had only 40% of memory available on my phone, which means about 800 MB, and I couldn't take advantage the rest of the 2+GB memory because phone has couple hundred apps preinstalled... Now I started clearing and un installing all these unnecessary apps and now I have about 1.6 GB memory available on my phone, and as a result of that I was able to get two days battery every day. Basically I can't finish my battery in one day regardless of the usage, which is really good....
Haven't used a task killer in a long time. I looked out of curiosity and there is a massive laundry list of extra crap going on.

Thanks for the info. Can you please tell us what apps you were able to remove to cause the excellent battery life? In the order starting with the one that uses the most to least if you can. Appreciate any help you can post from your testing. Thanks

Well, twospirits made this list of all apps https://docs.google.com/spreadsheet...OksNUB7oHFBsI_OoEQHgeGg7_l4/edit#gid=32644709
So what I did is: I categorized my apps in to three categories: 1- Apps that cannot be removed nor disabled, like Bluetooth speaker and etc so kept those as it is.. 2- the second group are necessary apps like Google play, browser sms,dialer and etc.. so I moved those apps to EX Sdcard, the only exception is youtube which gives me FC, so it has to be in the system..
3- the 3rd category is the rest of the apps which I removed from my phone, like S Health knock and other hundreds...
Now I have almost 2gb availabe memory on my phone which I think it's very good, and that's the reason I'm getting one day of very high usage or two days of normal usage....
Please check my screen shosts, almost two days with 5 hours of Screen On time or 7+ hours in one day....
Thanks for the info. I will work on removing apps that I don't use from the list and see what improvement I can get.
Just wanted to explain a few things.
1) moving apps to external SD Card will not free up RAM. It frees up internal memory (/sdcard or /data) but should not affect RAM.
2) unused RAM is wasted RAM. In this case you are saving battery because some of the apps you deleted were using CPU cycles or keeping wake locks for some reason. The amount of energy used to keep an app in RAM may get you a few extra hours of battery life at most. Your biggest 3 battery killers are Screen, Modem, CPU. In that order.
So good job getting better battery life, and I'm going to be using that list to delete some crapware. But your conclusions in why you saved battery life are a bit off.
Ok this is what everyone in this thread should do before they comment on memory usage,
1. N910C or N910F (Snapdragon or Exynos?)
2. Debloat or not, all apps active (stock)?
3. Debloat with root?
4. How much time without reboot, test of memory usage with or without reboot?
5. Screenshots of disabled apps section of your storage
Me,
1. N910C
2. Debloat, disabled quite a bit services/apps
3. No root
4. Fresh reboot, just now, test of memory usage = 1.52Gb only Wi Fi File Explorer in background.
5. Turned off apps,
Please, i know every device is different but try to follow my little Q & A, in order to get a general idea how much memory does you device use.

Sir, First of all I'm not a dev, and probably you know more than me about these things but let me ask you this:
Even though I've already deleted unnecessary apps from my phone, but still I was using 70-80% of my phone's memory all the time, and my battery life was one day or less than that .....
I decided to move all my apps to ex-Sdcard which made me using only 30-50%, of my phone's memory and the battery life from one day to two days!
So since you said moving apps to EX-sdcard won't make difference, could you explain to me this situation?
Please go ahead and check my screenshot, I'm watching MKBHD'S full hd video and I'm only using 37% of my phone's memory.
Thanks again.

Were you perhaps plugged into a computer? You lose the ability to use SD Card apps when plugged in.
I'm definitely not a dev, I just know electronics and a bit of basic computing theory.
Using less RAM shouldn't save that much battery. What may have happened is one (or more) of the apps were auto-starting and using CPU cycles to do something not important to you. I'm not sure if SD Card apps can auto start or restart.
Like I said the information you provided is good, just the comclusion of less RAM means better battery is off. Well programed apps should sit in RAM for quick access but not waste CPU cyles on things.

You right, I think maybe EXsdcard apps won't auto start and that's what saves my battery. When I check my running apps I cannot see any user apps in there, no facebook, what's up, Browser or any other user apps, so maybe that's is the case.... The only down side of my situation is that I have to manually open Facebook to see latest notifications which honestly I don't mind it because I don't need facebook and twitter running 24/7?

You should NOT be using task killers on Android! Advanced Task Killer, or any task killer, will shorten your battery life instead of extending it. Android actually knows how to handle itself quite well, and will keep certain things around for a reason. Google created Android and just might know Android a little bit better than those 3rd party app developers.
Also, I see in your other posts you keep calling a micro-sd card an ExSdCard. If you think about it, "Ex"SdCard would actually mean "Previous"SdCard. It's called ExtSdCard, meaning Extended SD card. And FYI, there is no Android Market anymore, it was replaced by Play Store years ago.
Before i start, let me say that i'm aware how Android use the available memory to cache and safe battery life/cpu cycles for future stuff, but....
I had LG G2 with Cyanogen mod, which was using only like 700 megs of memory! leaving like 1GB free and made the device fly. Now, on Windows generally things start to get junky when you have only 15% free of total system memory, what is the general conclusion with Android, at what point does you device become slower, how much ram (%) should you have free in order to work as fast as with 50% it should?
Because few mins ago, i saw 2.5GB memory usage, and the device get a bit slower then usually, it was noticeable even though i had only like 6 apps turned on. Is there a way to lower the memory usage and leave more free for multitasking purpose, and general device performance, i know this might be counter productive but with root - debloat devices get much faster, memory consumption is much lower, so i think there is a connection, and it should be beneficial.
Just got a new s6 edge+ and absolutely blown away with the phone as a whole.
Only problem/issue is the RAM usage. I'm a light user for 90% of the day and i have barely any apps installed, yet the RAM is always above 50% even when all apps are closed and i 'clean' the RAM. Average RAM usage is 75%. 3GB?!?
Is this normal to all other users? My thought are that it could be a false reading. Or that it could be dummy using RAM and reassigns it to wherever needs it when any high usage apps run.
I am a UK user and the only update applied was a carrier pushed update. (E.g. i havent done any updates myself or messed around with the phone).
Attached is a screenshot of my kernal and baseband versions for anyone interest.
Any thoughts would be appreciated, thanks, Zack.
I see the same on my SM-G9827 phone.It opens around 30 apps in background.If you clean them regularly it kills the battery.Its better to leave them like that.I am getting 6 hours SOT with 3 % left if i leave them as it it.
Ram is ment to be used. To make apps open fast when you need them. A lot of free ram does not make your phone faster AFAIK. So keep those apps running and enjoy a fast phone!

I agree.
RAM is meant to be used, you've got 4GB of it. The OS has been optimised to kill any processes that haven't been used if memory is filling up. Forget about saving RAM and focus on enjoying the device.
