[Q] more ram consuption?

Hello all
i am kinda new to android
so i installed a task manager which shows me my current amount of RAM
and i found that only 50-70 MB of ram is available with me always
and also when ever i try to play NFS shift on mobile it gives error of less memory
so is there any fix available
also is it normal for everyone ???

It doesnt seem normal for me. Mine is usually in the range of 150 MB to 200 MB depending on the tasks in the background. I use my i9000 for development and dont play games too often (except on my smoke breaks.... )
There are no "fixes" per se. You might however consider using "ATK" (Advanced Task Killer) or "Task Panel X". According to my observation as you keep using the phone for a prolonged period, services and apps will keep getting consuming resources even if you apparently think you had closed them. Its really an honest mistake pressing the "home" key to "close" applications, but I do it all the time too....
You could use ATK to close apps other than those in the "ignore mode" (a feature of ATK) after a specified duration. Does wonders to my RAM
Cheers....

Thanks a lot dude for your reply

[Q] ignore Apps in 2.2 Task Manager

how the title says how can someone ignore Apps which are need like (sms time fix) when one clears the memory and not having to restart the app every time after clear memory

Just don't use the level 2 clear and you'll be fine. Only apps you should ever kill are the ones that show up in "Active Applications". Except for your launcher of course. Killing system apps and services is like shooting yourself in the foot.

How so? Could you elaborate?
I'm sincerely curious as to why the L2 clear is a bad idea.
Thanks, dude!

Clearing L2 level cache kills essential android processes too, and system would again need to restart all the needed ones again. Read abt 'android memory management' (link in my signature), and see if that helps.

App data is stored in RAM so that you use less CPU the next time you run that app. RAM uses much much less power than CPU, why would you want to have empty RAM?
If an app in your task manager shows cpu % next to it, then close it because you don't want the CPU to be used at all.

As the previous two said, why would you need to have RAM free?
This is not like BBOS, which needs like 25% memory free in order to start an app.
The whole reason for having high RAM is to use it, if it is always free (unused) what benefit do you get from it?
Using task killers or freeing up memory in order to save battery is only going to drain your battery more.
Android loads programs into memory based on what it deems needs to be available to run quickly... and once you kill it, it will use CPU to load it again shortly thereafter.
CPU is a bigger drain on power than letting programs hang in memory.

[Q]Does Quasar kernel support swap?

hi guys,Does Quasar kernel support swap?and how to enable it?
i tried to enable it but failed
and i'm thinking about there's a lot of free space that i never used in /data and /system,so why don't we use those useless space to swap for more ram?
or we can use ZRAM?and how to use it?

we have 512 mb memory, for what you want swap?

actually the ram we can use only have less than 300mb

hmm partitionning SDC should do the job, isn't it ? do "ext" partitions have something to do with that ?

I think there's no reason to use swap, but dxdiag32's idea is not bad... internal memory is quicker than sd...
Regards.

Nah, it doesn't support it.
I did some tests with ZRAM and ZCache back in the LG P500 days and it didn't seem to help with anything so I usually disable Swap support now.
Anyway, you can always mount a tmpfs partition to some applications to boost their I/O operations if that's what you're looking for.

Depends on the microSD card's class. A class 10 is faster than internal memory.
In fact, it's a shame they dropped the yaffs2 filesystem as in non-sequential I/O operations it's the best one.

Class10 is faster? At least internal memory will be less energy hungry... won't be?

Yes, class 10 (>= 10 mb/s write speed) is faster than internal memory.
This is why moving app, data and dalvik to microSD when you have such microSD provides a good boost on I/O operations. There's many folks using the combo CM + S2E + MicroSD Class 10.
As for battery, it's a good question but I bet it should be the same. I/O stuff isn't heavy.

most of us now is using C4 sdcard,at least in China is .so i wanna give us some more performance.my free space in /data partition keep more than 800MB for a long time,and i think more ram can provide us more stable phone.

Beware that RAM works differently for Android devices.
Whereas free RAM in Windows is arguably better than occupied RAM, this is not so for Android. In Android, having RAM allocated is good which is also behind the reason of why we shouldn't use task killers. That being said, we don't really need more than 512 MB of RAM for a heapsize of 32 MB and proper OOM groupings and adj values! Even with an aggressive usage, it's unlikely you'll manage to trigger an OOM (out of memory) throughout your day.
Here's an oldie but goldie article regarding this:

ok got it , thanks knzo

I understand the theory but because of my own experience I do not agree in 100% with You. My previous smartphone was Samsung Spica ( not much RAM ). I used to use my favourite IGO for navigation. It was impossible to succesfully launch IGO if I have not used task killer before.
Without task killer IGO just started and vanished within seconds.

That's because IGO triggered an OOM event and the ROM you had instead of doing an intelligent swipe and killing applications based on certain heuristics, was killing the process responsible for the OOM instead (IGO). It's a flag in sysctl called: OOM kill allocating task.
So in that case, it was just a lousy ROM/kernel. Or perhaps in Spica (old kernel, old android version) there wasn't this setting and the phone always killed the application that made the phone run out of memory. This explains why it vanished after a bit.
Either way I stand correct, there's no need for task killers in a device with >= 256 MB of RAM or properly configured.

Agreed. I still have my old Galaxy Apollo, with 256 MB ram it goes perfectly as it should. In fact, on a careful observation i 've noticed that if we use taskkiller at autokill level at let's say 30 minutes autokill, it will technicall consume 4 CPU cycles in an hour for each app (two for killing, and two when applications like gmail/facebook etc. starts automatically again).. but without taskkiller they may have stay idle, and not used any CPU cycle at all for as many hours as phone is idle. And for battery purpose, it is the CPU cycle that drain, not the used memory !

in my opinion,we only need to kill the apps that use internet in background to save battery.such as Google Maps,once i used it,its services stay in background and after 3 hours i didn't use phone do anything,battery drain 3%,and if i kill it,no battery drain after all

Google Maps and DRM service process sometimes cause battery drains indeed.

i deleted DRM service,and seems it's no harm to system

Lol but do you know what is it function ?

I've seen drm using a lot of CPU as well from time to time. What is it used for and how would you go about removing it?

You can use Titanium https://market.android.com/details?id=com.keramidas.TitaniumBackup
-Go to Backup/Restore tab
-Find by DRM Protected Content Storage
-Click and select Freeze
Now the app is Freeze and the system don't see more!

[Q] ROM with much RAM free

Hello,
I'm looking for a good ICS ROM with much RAM memory free.
I know there are many good ones like RocketRom, but the RAM is priority for me, as I use a lot off apps and I don't want them to get killed every time I exit them.
The ROM may be stock based (best) or even some other type.
Do You know some You could recommend?
PS. They don't have to be fast as hell.
Admin please don't close this thread.

try bulletproofing them and freezing/removing unwanted apps.
Also try to set autostarts off for apps you only want to run on request as well as proper exiting them to prevent running ram.
granted its android that should optimize ram usage which is why amount of free ram shouldnt impact, but yet it does.
maybe you have set dont keep activities to on development settings if so, disable it. lol.
Other tweaking can be done with minfree and oom levels to lower values, stock however they are pretty low.
last random thing I can come up with is less memory footprint apps. Alternatives for ones you are using. Lol. Goodluck!

I have used about 170 apps on my SGS2, now I've reduced them to about 120. I have also deleted some system apps, but the problem is android OS.
Killing apps is disabled for 100%, it's just due to 70MB memory free. The launcher is killing almost every time I turn on some other app (build.prop edit didn't stop it from closing).
Android just uses too much RAM. Fresh ROM uses 400+ MB, that's so much.
That's why I'm looking for some ROM that uses max.300MB. Are there any?
I wish I could have ROM from my xpiera x10, which used max 120MB hehe

[Help] RAM Manage AICP ROM

Hi all,
It's there any way to fix my phone RAM consumption, because it's lag many times.
At the first boot, Free RAM takes 1200MB then down to 350Mb even though clear all recent app usage.
Here my phone detail :
Mi5 64Gb
Android 7.1.2 AICP 12.1-NIGHTLY Build date Apr-17-2017 with default rom kernel.
Any comment are appreciated, Thanks.

Android is supposed to keep RAM as full as possible and removes items as soon as more RAM is needed. As the saying goes; free RAM is wasted RAM. Trying to free it up manually will just make your phone slower as it gets confused as to why its cached processes in RAM are being removed, and it will just try to fill it back up again.
If your phone is lagging then something is using up a lot of cpu. However don't use a task killer to stop it! This will just cause android to keep starting the process over and over. The only way to make an app use less cpu is to uninstall it.

Hi ingrinder,
Thanks for you information. Is there any way to see what app takes more cpu & ram or something like that? because I only install app for my daily activity.

Since they removed the CPU usage overlay in nougat, the only way I know of is to connect the phone in USB debugging mode and use adb to run this command:
Code:
adb shell top -m 10
