Can you lower the ram usage? - ZenFone 2 Q&A, Help & Troubleshooting

Hi there,
I have the ZF2 with 4GB of ram. After a couple of days of usage, it seems impossible to lower the ram usage below 1.8GB even when I clear the cache of all apps.
However, when I restart the device, my ram usage is below 1GB.
I have uninstall or disabled every app I could without rooting. & I don't want to root now.
Nonetheless, I would like to keep the ram usage of my device as low as possible (2GB of ram use seems a lot to me, especially when I have one or two apps open)
Did you find a tricks or ways to keep 2gb or more ram free at all time ?
Thank you.

Simply, there is no clear way and those numbers are normal. The best memory management is with native linux, not yet available on zenfone 2.

What's the point of always having 2gb of free ram? RAM is completely useless if you aren't using it.

It's not a question of useful or useless. It's a question of is it possible and if yes, how.

Yes, keep the phone in deep sleep with all apps closed and disable everything in autostart , better yet, you can just power off the device
p.s: not even custom roms will run that low, I had cm12.1 with lg g3 3gb ram, I disabled basically everything and phone will still boot with at max 2gb free ram, maybe 2.2gb if you start killing launcher and sytem apps lol
4Gb ram with 2.2-3Gb free Ram is plenty for a cellphone. Its even plenty for a desktop unless you run hard core 3d games like crysis.
The lowest I have seen is 150Mb/1Gb usage with Nexus 7 v1 tablet yet it was hell slow. Note that the more Ram you have, the more the system will use it and cache in it. This will increase apps loading speed since they are directly loaded from Ram vs local storage.
I would love to have an app that lets you select what to cache in Ram, e.g. large high-resolution PDFs that take forever to open and load :crying: I have 300-800Mb PDFs that will take 1 min just to open.

Indeed, an option to decide what to cache would be great.
Can we expect less usage and caching with the 5.1 update or with a custom Rom?

[HELP]Why my ram is above 160.

I have freezed the unuseful apps and im usin startup auditor, Why my ram is still too high? What can i do? Please help
Try Supercharger or [email protected]'s scripts. The threads are just a few blocks down.
Well v6 isnt effecting too, i used build prop. i wanna use local prop. its effective.
I use auto memory manager and my ram stays between 90 to 120 without any special scripts!! Try it and tell me if it wrks

IMO having less ram is not a good idea in android device. android device has different ram management. when an app is started, it will be stored in ram's cache to make it started faster when it started again. when the ram is almost full, it will automatically delete ram's cache and stop some some app. in this way, android devices will have better performance and battery saving. its almost useless to clear ram except in some cases when we need a huge ram space to run a big program.

I dont understand you. When i clear ram its 80+ but now its 130+
Kurotsugi post is cent percent correct.
You shouldn't run after cleaning your ram
I'm having 220+ ram for average use. my zenonia 4 is running smoothly and never got a problem with any app. as I've said, android device will store recently used app in its ram cache. thats why the ram usage will raise rigth after you clear your ram and start to use some app. this is normal and won't affect in your device's performance much. I thought our ram setting is balanced between running app, background app, and system app. you can change the setting with ram manager pro or minfree to have more space for running app and background app.
Exactly! So much of fuss about RAM. My RAM consumption is always 240+, even after a reboot. Never had any problems.
Woah 240+?? what u are using?
dont forget,only used ram is good ram in linux(android is linux).greeeeetz

240 is my minimum RAM usage. Well, Go Launcher, Go SMS, Go Notification, Go Locker and AI Type Keyboard are always running in the background. xP
Try [email protected] scripts
Try [email protected] battery and RAM Saver , Im using it and my ram is just consuming about 132 - 109
Im supercharged. It'l conflict.
more RAM = more battery consumption ?
more ram doesn't always mean your device will consume more battery. yes, its true that our device use more battery power to start up the program, write the onto the ram and run them. nevertheless, linux have unique method to save more battery. after a program is minimized, the program is not erased from the ram. it will be stored in ram's cache. in this way, our device could start the program without write the program onto the ram again. this method will avoid to repeatedly write and erase the program on the ram which consume a lot of battery power. this is also the reason why most android program doesn't have exit option.
owwww , thanx , i hav a bad habit of clearing ram every now and then , even if it is at 130 or 150 ..
m not gona clear it now unless system be lagging
that's normal if you have 160 ram that's the lowest ram that i've reach in my galaxy y even i press the clear memory its still 160 or below... if you feel that your galaxy y is lagging why you dont want to try Andrenaline Engine that imbawin made even if you reach 200+ ram it still fast even your ram are 60MB left

High RAM usage?

I've noticed on my e975 EU version even with 0-1 apps open the ram free is only 1gb... Other phones have far more ram available including my previous nexus 4. Anyone else notice this? I often find with quite a few apps open I only have 2-300mb free
I've never seen less than 500mb free but its true. Never more than 1gb.
I checked earlier with 0 apps running it was at almost 1gb used.. what on earth is using almost 1gb!? If phones with only 1gb can use less than that on jelly bean.. why does this phone use so much?
According to ram usage i am using approx 400mb, task manager says im using 800mb. Maybe 400mb is reserved for system? This is on stock rom with only a few apps installed.
Keep in mind free ram is wasted ram. Free ram is like having a fast car and only using first gear. Still curious to know where it all ram is used nontheless.

I get what your saying with 'Free ram is wasted ram' but when you run out of ram.... things will start to stutter.
Having a few apps open to find you only have like 300mb left is insane.
I've had phones with only 1gb ram before and with lots of apps open they are using like 700mb/1000mb... it's almost like this phone is going 'Oh I have 2gb available so i'm just going to chomp up 1gb for the sake of it and leave you with 1gb left....'
If you're root use an app called "Greenify". Simply hibernate the apps that don't use adding to the list of the app, then add the widget to hibernate the app that you added (all except whatsapp, twitter in my case). In addition I use a tasker manager (don't added to greenify) and add a widget too, that combination gave me 1,2 gb free using a lot of widgets
Im stock un-rooted.
I only have 2 widgets on my home screens, 1 is the standard world clock and the other is play music. Tried removing both and it barely made a dent...

That's weird, only 900 mb free?? Mmmm, try using advanced task manager from the play store (I don't remember if root is needed), that will free you more memory. But in the 900 doesn't mean that the phone will be heavier, backward the used ram is exploited to make the Optimus lighter
Seems odd eh...
I also have 600 - 700 MB of RAM when I do not use anything.
There are just icons on my homepage, and a calendar widget (stock one).
At this case, It gives me 600-700 MB of free RAM. I always use "clear RAM" button. But why it gives us so limited free ram?
I used to use 4X HD with 1GB of RAM. There were 350-400 MB free which almost same with this optimus g?
Can someone explain this situation?
Or I think we need a new update. or CM10.1
It just feels like the phone is using up too much or isn't optimised properly.
As said above, phones with only 1gb available use about 3-500mb... Our phone with 2gb available seems to use about 900mb-1gb with nothing running. It's like it's gone 'Oh there's twice as much free so I'll just use twice as much...'
What about the AOSP custom Roms ...is the ram usage is same on that kind of Roms too?
Sent from my LG-P500 using xda app-developers app
No clue, i'm 100% stock unrooted Maybe someone will know.
My nexus 4 was far better at ram usage than my optimus g mind you. No matter what it never used more than 1.2gb
I think the Lg UI(stock firmware) is a memory hungry ...i suggest to try AOSP roms with lg skin :thumbup:
Sent from my LG-P500 using xda app-developers app
Using cm10.1 and have always about 1.4gb free, and this is more than enough for everything.
Y, stock rom have a crazy high ram usage, now im on PA and got 1.2gb free.
My doubt would be if, on stock rom, you get many slowdowns when you experience this high RAM usage. For me (who doesn't still have a LGOG, but is seriously thinking of buying one), it's the thing that matters most - if the lack of free RAM results in worse usage.
Otherwise, most efforts could do more harm than good - a task killer that kills an app which will restart seconds later is wasting RAM and battery instead of saving them.
I'd give priority to greenifying unruly apps you need often and freezing apps you rarely/never need but won't/can't uninstall (with Titanium Backup, or any other app that can freeze system apps) - always making sure you're not freezing some system app that will bring your phone to its knees. With this well configured, I'd say a task killer would only bennefit those of you that rarely use your phone. Everyone who often takes it out of their pocket and updates Facebook/Twitter or plays games should let Android take care of itself, as it will keep in memory the apps you've been using the most - as it should.
Don't use task killer apps, they aren't good for Android. Maybe something like a LMK Manager but you need root to change lmk.

M$ Windows does the same thing - if you have 2GB it uses only the half, if you have 8GB is use nearly 3,5-4GB. I think it preloads a few things including the most common used apps in memory perhaps?

Using a lot of RAM... for some reason?

Ok so I was running an app to check on CPU speeds (unrelated research) when I noticed that this same app was saying I only had 340mb of RAM free...
This seemed a bit strange, considering this tablet has 3GB of RAM on board, and I'm not really running anything at the moment.
I went into the storage setting page, and looked at running processes, and it says that I am using 2.5GB of my RAM.
but... if I add up all the ram usage on all the running processes, it only adds up to about 500mb....
So what is using up the other 2gb?
If anyone has any suggestions, it'd be nice, as at the moment it seems I only have 1gb of usable RAM in this device...
EDIT:
Nevermind, I think I solved it... sort of. I found that the ram clearing button is in a different place than I remember, and I have managed to clear out some more space... though even after a full reset 1.5gb of ram is immediately being used. Seems a lot.
Though this is a stock rom etc so I suspect thats normal.

You probably aren't using all 2.5GB for actual running programs.
Windows 7 does a great job of managing money. If it has any unused memory it will hold often used programs or data in memory in case it's needed. If a running program needs that memory it's quickly shifted. Otherwise when you reopen that program you recently closed, it may load quickly from memory rather than from the drive. I suspect Android does things similar.
Modern systems programmers consider "free" memory to be wasted, so they put it to the best use they can anticipate. That gives you the benefit of all memory as often as possible. If they only allowed the memory to be used for what's needed right now, your Note would only have about 1 GB memory, and would be considerably slower.
It's a little like having the cook wash your car while waiting three hours for the turkey to cook. You get both the turkey and the car wash.

I used Windows 7 as an example because I know how it works. Like you, I imagine Android 4.3 does the same thing.
I was wondering about this as well. On my Note 2, when I clean the ram, it will go to 480-500 / 1.75g on this tab, ext I could get is 1.33/2.75.......
I went through and turned off a lot of the apps, it helped free up a little bit.
Does anyone have a list of the apps that are safe to turn off?

I have LTE version with Snapdragon and when I start the tablet, it uses about 890MB of 2,35GB available (yes, it has 3GB RAM, but graphic processor uses some of this RAM)... When it loads all apps to RAM (about 50 of them, we know android do this) and I start few apps(FB, Gmail, Chrome, Hangouts for example), I still use only about 1,3GB of RAM... So almost 1GB is still free
In Android having too much free ram is not a good thing. Let your apps use it, you don't have to worry about not having enough ram, OS manages it well for you.

Android is a mobile OS which means that it can backup and restore not needed apps if necessary and the 3GB are only the runtime memory beside this it can use the whole internal memory for "running" apps. So long Android got enough memory it holds all apps in memory which speed up the whole device. Therefore it is positive that the Note use his whole 3GB memory and don't think that killing apps or free memory will be a good idea. It will slow your device and produce lags.

They are both right. Android is based on linux. Linux uses ram very effectively to cache apps and data to speed up your system. When something needs ram it removes a different app or data from the ram to keep moving. It works totally different from Windows. Check out this article.

If you want to change how your ram is managed, and you have root, you can use the v6 supercharger or a simple minfree setting app. V6 is in the developer section of the general android forum on this site. I've found that m ram fills up from cached apps. V6 will let you auto clear however often you want.

How much free RAM are you guys getting?

Im on 10.5. 4.4.2 NFB. Debloated rom. Stock kernel and touchwiz. Most services frizes. Even samsung accounts.
Omly get 1gig Free RAM.
WHat the heck is the rest of the 3gig RAM being used on?:silly:
It is used for caching etc. Same on Linux.

i have about 60% free , maybe about 1.5gb in use ?
Yes, after fresh boot mine shows 2,71 GB total, 1,6GB free, 0,98GB in use.
But after launching (and closing) couple of apps it should use all RAM for caching finally. You do not get it back free even after killing the app. So this number doesn't say anything. What's in the cache depends on what you have been doing so far.
Don't forget a considerable chunk of ram is used for the screen's memory. The Nexus 10 has the same screen resolution as the Tab S and it's overall free memory is reduced due to screen resolution.

1 GB is reserved for swap. Usage can be viewed with disk info app.
mine varies around 1GB free however not all the time and why i feel that 3GB of my S allows it run much better than my Pro 10.1
i really dont care about the status of free vs used etc.. UNLESS like i experience on my personal computers it becomes clear a device just needs more to function smoothly.
my example i have a Mac Mini that was running sluggish and with 4GB ram it generally had about 800MB free during my workday. i installed 8GB ram and now it generally sits at 5.7GB used all day where when it had 4GB it sat at 3.2GB used
point is the Mini wanted about 5-6GB Ram to settle in around but would run on 4GB if it had to with constant work to keep 4GB limitation working.
i find that with having a 10.1 Pro and 10.5 S that more than 2GB is needed and 3GB seems to be enough but can tell when the 1GB is missing on my Tab Pro.
Using clean master, genic and disable many Samsung applications I've reach 1,37 Gb used of 2,7 total.
No lag using games and chrome beta.
Some application is possible to disable only via the drawer.
Correction... 1,33... :silly:

System using high RAM

Hi guys, does your RAM usage for System is around 2.7GB - 3GB? (Under "Developer options > Running services")
Previously when on Nougat, System usage of RAM is around 1.7GB to 2GB. But ever since upgrade to OOS 5.0 and then recently to OOS 5.0.1, it goes up to 2.7GB and sometimes even 3.1GB!
I'm rooted using SuperSU, I try reflash rom and use magisk but the System still use around the same RAM.
I have a handful of apps that I frequently access usually cached in the RAM. During Nougat time whenever I open back those app it will open immediately, indicating that it's still in RAM. But now I have to wait the app to load, must be because of the System is using additional 1GB RAM that makes my apps being cleared from the cache.
Is it OOS 5.0.1 use so much RAM for System? Or there's bug on my system? Compared to Mi A1 8.0, it's System only use around 1.3GB RAM.
Is there a way to make the System use less RAM? Or any other custom ROM where it's System use less RAM?
My OP3 with OB29 is eating that much ram too but it is not problem for me because we have a loot of ram
Magisk 15.2, Google Play Services doze module, no other modifications.

So I guess it's normal for 1+3 Oreo to use so much RAM for System? That feels like poor optimization from Oneplus developer. Even Windows 10 system use around 2GB or less.
I have a handful of apps that I prefer to be kept in RAM cache, it's annoying to have to wait for these apps to be load again every time I access it.

Thats because most of windows 10 does its stuff off machine.
Unused ram in android is completed wasted ram. The more options you add to a device the more ram usage it will take. Not to mention apps are second rate when it comes to ram usage. Its more important for it to be used on system stuff then on apps.
Also with the way doze works. Your apps will have to reload alot anyway. So its just something to get used to.
Where is the problem? We have 6gig ram...

System usage on Nougat is 2GB, now jumped to 3GB in Oreo. That's a big increase, considering that other devices with Oreo can get by with around 1.5GB System usage.
Even with Doze, if the app still stay in cache it would be load immediately compared to app that have to be fetch in storage. Because of this it feels like Oreo is slower than when in Nougat.

What do you expect? With each update comes more features. With more features comes higher ram usage.
Again. Unused ram is wasted on Android. It doesn't even remotely work like it does on windows.
If your apps are reloading then there is something rom with the the setup. Be it the OS or what have you.
I normally am about at 1.5gb when I'm it using my device. Mind you I don't care about keeping apps in the background. When I'm done with them I completely close them out.

But don't you think 2GB jump to 3GB is high compared to the features added in Oreo?
Supposedly my frequent accessed apps should stay cached in RAM, but because not enough free RAM it was flushed, presumedly because those apps don't have elevated priority compared to System apps. Missed those days where we have more control of the RAM by using minfree and can set ourself each app priority value.
Your 1.5GB is your System usage of RAM?

So I downloaded all the necessary files and updated to latest TWRP 3.2.1.0.
After wiping my System, Cache, Data, I thought of change the file system to f2fs for some speed improvement. And proceed to change file system for those I mention again, and forgetting that doing so will format it, and Data is linked to Internal Storage...
My internal storage is wiped clean... And I didn't make an external backup... :crying: :crying:
Expensive lesson to learn, always do an external backup even when it's tens of GBs that will take long time to finish. :crying:
