Ram management - Huawei Mate 9 Questions & Answers

Hello guys
Does anybody know a way to increase the number of background apps that can stay opened???
No matter what is the free size of my ram, I can not keep more than 14 to 15 apps in Ram (Even when I have 1.9 GB of free ram)
In oneplus 3t you can modify Build.prop to change the number of background process but I've not find a way to do this for my mate 9
I think Mate 9 ram has two limits :
1- Close down apps when the number of opened apps exceed 15
2- Close down apps when the free memory is low
is there any way to disable the first one or at least increase the number of apps ???
any help would be appreciate it

anyone??

Why do you need to?
Not a criticism. I'd just like to know what it would achieve.

I don't like that white screen in reloading apps like Phone , Messeges , Settings and some other
It looks so much cooler to open these app in a glance

I don't know about you but for me I prefer to use the most out of my phone's memory before it start closing them down
why my apps should close down when I still have 2GB of free ram ????

If you ever owned samsung s3 you would know what memory problems are. Anyway phone needs to keep enough free ram in anticipation for opening new app, and amount of free ram is set so the phone does not crash if you open a big ram hungry app. As I understand it is really a fine line between how much ram is free and stability of the system.

Hello everybody,please give me some use feeling that i can improve my software.
It is my understanding that this is not useful for Android 2.2 and above, since it includes its own memory management.
Android will usually keep its memory full on purpose so recently used apps are responsive.
When you load a new app, others get swapped out of memory if there is not enough room.
So is this app useful for 2.2 and above?
Useful to be able to help you more quickly free memory when you reset oom value ,the system will speed up Significantly
hi nice working so far! looking good and quick boost is really a nice touch!
my mob is running fine without any problems so far.
like whitelist, a blacklist would be helpful! and the memory is not going beyond 120! when using other memory tools such auto killer memory or minfreemanager I can tweak upto 250! I think you can give option like save as custom preset and then use it.

This isn't like a typical task killer. This looks the same as the very popular AutoKiller. It tweaks Android's built-in memory management. You can read technical details here http://andrs.w3pla.net/autokiller/details

If you can get root, and setting successfully, the system will help you free memory. the system will kill some empty applications when you run many applications.
auto launcher is working for me!
but everytime I open I have to click request root permission! is there a way to remember my selection! once I press request root permission it should remember.

"topspeed" need root, "quick free memory" does not need root,topspeed can completely free the memory and kill some empty app. "quick free memory" only kill some empty app.

[Q] Info about RAM

HI
Yesterday I bought my Asus TF300T ... awesome but there is one thing I do not understand.
The tablet have 1 GB of ram... but if I go in settings -> application -> Ram in use show 680m occupied, and only 290 free.... strange cause happens at every boot!
So I begin search in this forum for some help, but I was not able to find any specific info about ram consumption....
Now I tried to install a custom Rom based on 4.1.1 (Clean ROM 2.1 ), but nothing has change, the ram consumption is the same as the stock JB version.
Just now i've try to remove some bloatware with TitaniumBackup, reboot but... 650m in use is too hight.
Can I have some information on the consumption of ram? Can I do something to increase the free space? I ask because I saw that some users have more than 600 mb of free space at boot
Thanks for any replies
Mirko
PS sorry for bad english! I hope you undestand :angel:
You can leave it alone for the most. You won't gain anything by having more ram that isn't being used.
This is how Android is meant to work. It caches process and stuff in the background so apps boot quicker. If an app needs more ram, the system will close processes to free some up for you.

Hi mozy!
Uhm ok but if I want to disable at startup one or more applications/services how can I do that? I undestand that android caches process but I wanna be able to know "what's inside" my ram and exactly how much it take. There's an app for this?

If you want to disable apps at startup you can download the app: "Autostarts"
from the Android market and for your second question check out the app "AutoKiller Memory Optimizer", also from the google play market

With 800 MB of RAM free, why do apps not stay in RAM when multitasking?

I presume that this has something to do with the min free values, but I'm not sure what to do about that or if I should modify it or what. What are your thoughts? I think apps shouldn't start being suspended until you're at least down to say 200 MB. it doesn't take long to suspend an app and push it to ram, android shouldn't be doing it so aggressively.
To test this yourself, open up a lot of apps, use the task switcher button and then scroll to the very top and select the least recently used app do this for about 10 apps, and you will see that every single one of them is pushed out of RAM and has to be reloaded, every time you get back around to it again.

Maybe it has to do with the fact that kitkat is supposed to run on devices with as little as 512mb of ram.
iive ound coming from jb that KitKat agressivly kills task or dose a better job of it jb stuff was always running in the background.

interesting. thanks. Does the other RAM go unused? Maybe it's just suspending the app not flushing to disk.
on my phone ive got a woping 1.1gb free wen all my apps are closed this is just crazy like the guy above said I think kitkat is quick to suspend apps making it easyer on devices with less ram all found that when I clear a app from recent menu that it kills it off were on jb it would still hold it in ram tell another app pushed it out.
I read somewhere that kitkat can only have 10 apps open at once. Anymore and apps are kicked out of ram. Idk if this is what is going on or what

Probably for the same reason that Microsoft did the same when with Windows 7. Just to make the complainers feel better.

People used to cry all of the time due to Vista's prefetch doing its job. I've seen the very same thing here with 4.2.2's memory usage despite it not causing any issues.

Nah some of us read before replying. Basically until somebody makes a way to stop KitKat from killing apps when it doesn't need to us users with 2gb of ram have a lot of wasted memory. There must be a hardcoded maximum running app count in KitKat otherwise why would it be killing apps when we have so much memory left. Supercharger has a way of removing or changing that maximum so that whatever minfrees you set will let Android manage memory properly without preemptively killing apps.
Unless you have a poorly coded app that is just eating up battery when it's not a foreground application, on Android it's better to have it running in the background so it can be loaded up faster when you switch to it. Unused memory is just wasted memory.
That's the jist of Greeenify except it take sit a step further and stops that app from relaunching itself so it stays killed until you use it. Most of the time it works but some apps can be stubborn buggers.
Ram not used, but many app stay on cache, thats why new ART need more space than dalvik.

[Q] Memory leak? GPE 5.1

Hi all, been doing some research on this subject, some say mem leak was solved, others say its fixed till 5.1.1... Please, anyone here knows how to solve this damn issue, i think its the famous memory leak, not sure, but whenever im multitasking for example using chrome with like 4 tabs opened up, running whatsapp, winamp, and... facebook, i go back to facebook, the damn thing opens again like refreshing feed from the beginning, freakin winamp closes up, damn chrome reloads the pages as if i was opening again after closing it, and there is a slight UI s%$# that apparently re-opens the launcher (stock), like if it loads all the icons and widgets again. Im really not sure if this is the stupid memory leak thing, but I perfectly remember it also happened on stock 4.4.4, just as it happens here. 5.1 is really good! And having my phone with stock GPE 5.1 battery life and performance are freakin awesome! I dont want to go lookin for a custom rom, not totally satisfied with bat life and perf. Stock is wayyyy better at this. However, on custom ROM I didnt have this issue at all. wtf is going on with stock roms carrying on with this issue. Please help, thanks in advance. This is all I need to get this thing working properly. BTW I am NOT having my RAM consumed when I lock the screen or anything like that. Its just that it appears as if the system cannot hold apps running in the background, when i get back to them is like if i closed them and opened them again. If im using just one app in the backgorund for example whatsapp, this does not happen, and even when i press home, the launcher wont have those stupid drawbacks, everything is solid smooth.
Another thing, not a biggy, USB OTG... I even installed stick mount from playstore but never opens up in ES file explorer, any ideas on that?
Device details:
XT1032, Android version 5.1, Stock kernel, build number LMY47M.M001
This helps somewhat, but requires a custom recovery (and root if you want to manually edit):

Chrome RAM usage in the latest updates is insane, and Facebook, well.. it's always been a memory hungry one.
I just think you are expecting too much for a 1GB ram device, there is a reason that recent devices comes with 3-4GB RAM

I actually used an s3 mini before this phone, and never had this kind of issues. Its the software gpe 5.1 which has this issue, I read its not only for the moto g and moto g 2nd generation, its several devices. Im currently running blisspop rom with 5.1.1 problem gone. Stock kernel, nothing modified.
Tip: I removed chrome and use lightning now. I've also disabled most of the other play apps.
I've done some RAM stress testing on my stock 5.0.2 Moto G to try and work this problem out. I don't think it's just a LMK issue.
Some of the 'free' RAM in Android is taken up by a kernel cache/buffer which should freely give most of it's allocated RAM back to the system before the LMK kicks in. On an old tablet I've got on 4.2.2 it does just that - if I use the Fill Ram app (find it on the playstore) to simulate extreme low memory conditions on my tablet cached apps are cleared and background apps start to get killed when there is about 60MB 'free' left and the Fill Ram app in the foreground eventually dies when there is around 40MB left. The tablet is only keeping around 30MB aside for the kernel cache/buffer.
Do the same on the Moto G and it's will clear the cached apps and start killing background apps at about 150MB 'free'. The Fill Ram app dies at around 90-100MB. So the stock Moto G kernel is trying to retain somewhere in the region of 90MB for it's kernel cache/buffer.
My guess this a deliberate tuning by Moto for UI performance at the expense of multitasking. Combined with the reduction of available RAM due to the allocation of zRAM swap and it effectively leaves the stock G with much less room for user apps to run in the background or be effectively cached than you'd think for a device with a 1GB ram chip installed.
I haven't really noticed any evidence of the famous Lollipop memory leak on 5.0.2 on the Moto G (it's a system UI leak) so I reckon Moto may have patched it.

Latest global update 12.5.4 extended memory

Ok, so I've upgraded to latest firmware 12.5.4 global rom, and I've tried the extended memory option in the additional setting that added extra 2mb of ram... However from the about phone all settings the ram shown still 6MB... Shouldn't it shown 8MB instead of original 6MB?
unrelated question but just want to confirm, do Global ROM uses MIUI Contact, Dialer, and Messaging app? or from Google?
back to topic:
maybe use cpuz or any app that show device spec?

Global use Google apps phone, contact, messaging.... Yep, haven't try using 3rd party apps... Just looking if it's standard across all user... I've seen other phone showing 6GB + 2 extended on the setting page.
To answer both questions.
Many versions of MIUI these days are legally forced to use Google Messages and Google Dialer. There are a few places where the laws against such don't exist and will ship with those versions installed. Overall I wouldn't recommend it. I also wouldn't recommend Google Dialer or Mesages either, they're spammy, lack features and counter intuitive.
Second
As far as extended memory, I'm on the 8GB/128GB version of the device and after enabling that option the device RAM stayed at 8 in every app I used to check stats. Built in specs app and also many other specs apps like CPU Z. To me personally 8GB is already overkill because my usage even in heavy gaming is always less than 4GB. The additional 1/2 GB added is done purely on a deep level and will not ever show. Besides, real ram and storage ram have HUGE speed differences and I'm not gonna slow my phone down by using my storage as RAM. Also do not want to cross the write cycles by using my storage as RAM.

Yep, I am using swiftkey and it does improve on the typing... So far everything works great... Only the signal is not as good as while using asus or Samsung..
You need to reset your phone.
Because there seems to be something else holding your phone back that's making typing laggy. No phone after the year 2015 should be laggy while typing. Whether it's 1GB RAM or in your case a minimum of 6GB.
