RAM Leak - Xiaomi Mi A2 Lite Questions & Answers

Hi,
i guess Stock Pie has a Memory Leak and Garbage collector doesnt work.
I background restricted some apps in Settings but all of them still works on background. I cant see them on the Task Manager but i can see the Ram usage on AIDA64 app.
What i did:
- i set background restriction to these apps. (64 app restricted)
- i select app restrict behavior to Frequent. (for all of them)
- Task manager is empty.
- Cant see these leaked apps even on Android 9's built in Ram usage feature.
- i tryed kill apps when leave feature on the developer options. (These apps garbage still stays on the Ram)
- i even set background app limit 4 (Somehow developer options closed it self and everything i set reverted back to stock when i restart my phone)
But apps still eats the Ram from the background. I know because i can see Ram details on the AIDA64 app.
Phone starts with ~1600'ish mb available Ram. Available Ram decreases when i open-close these background restricted apps. (Hey! I am restricting apps because i dont want them working on the background. Like a Google Translator, Mi Remote, Hd Wallpapers app etc. i restricted all but these apps still works.) If my phone's Ram decrease everything starts slowing down. I am seeing it and i can feel it. After 5 or 10 minute later Ram usage jumps ~2000 mb. Some pieces of background restricted apps still stays in the Ram and i cant avoid from it on Stock Pie and these pieces slowing down my phone's performance. I am not using 26 apps!! Maybe 4 or 5 apps i am frequently using. I dont want unused apps garbage on Ram.
Huawei's EMUI has a built-in feature to avoid auto-start apps. Some custom roms has a Wake-Lock blocker. But i dont have anything on Stock Pie.
I just dont want these apps garbage on my phone's Ram. Because of these reasons i can clearly say Mi A2 Lite's Stock Pie rom has bad garbage collector. Dont know Xiaomi modified it or not. Probably thats why Stock Pie roms consumes more battery than Stock Oreo.
I am not the man who believe 'unused Ram is a waste'.
I just want most important system apps on the Ram and other almost everything shouldnt occupy a space on the Ram. This motto is the key reason of performance for Budget phones on my perspective.
Rom details:
Locked - Stock Android 9 - v10.16.0 (November 2019)
What i am asking is:
- Which Roms has built-in feature to avoid from this?
- Which Roms has a best Garbage collector?
- Which Rom fits to my requirements?
Thanks.

You are fundamentally misunderstaning how task management works.
Restricting stops apps from using the CPU (and thus, the battery).
Android will leave unused apps in RAM for faster launching later. Some "AI" decides which of these to keep when more RAM is needed.
If it offends you to see these apps in a low-level task manager you can kill them. Heaps of task manager apps can do this automatically. You need something like greenify if you want them to stay dead.

I did not misunderstand anything. You didnt understand what i mean exactly.
Why Hd Backgrounds app or Mi Remote app should stay on the Ram even i dont use them? I am using them once a week or so. Thats why i dont need faster launch. Because i am not using them? Clear?Youre talking about app restart power consumption. Thats the point. I am not using them and i am not starting them in a single charge. Even if i want to restart these (as i said this thing happens once a week) apps restart power consumption consumes incomparably less energy than phone restart power consumption. I dont want to use my phone’s Ram with junks.
Do you prefer trashy Ram with bunch of junks? I dont prefer it. I cant clean these apps Ram garbage until restart my phone. The restart consumes a lot of energy and when my phones Ram become trashy i should restart all system to clean them.
Restart has benefits;
- More performance
- Clean Ram
- Better Battery life until Ram become trashy
What i am saying is why i cant use these benefits without restart. Think about all these power consumption when we restart our phone.
Its all about garbage collection and this thing doesnt work on Android Pie. I tryed Greenify gived it all what app wants still nothing changed. Ram still gets trashy and this causes; slowdowns, hiccups, more battery consumption,.. etc. Even my phone’s processor and battery doesnt like garbage on Ram.
I hope Huawei’s HarmonyOS will work better than Google’s trashy Ram management.

It's not junk. If you want tasks killed, get a task killer. If you want to prevent apps from starting, get a hibernation app.

The Chinese OEMS are notorious for evicting programs from RAM and preventing them from running in the background, fundamentally breaking the android API contract in the process. If you think that's better then by all means, go use one of those ROMs.
I for one got the A2 Lite instead of the Redmi 6 Pro precisely to avoid MIUI and its task management policies.

[Q] Why no ones talk about the lag cause by Insufficient memory

I notice the phone start lagging when there are less than 100Meg of available RAM on both 2.1 or 2.2 SGS.
Questions....
1. How do i make sure there will always be min 130 available when not in use?
I'm currently using Froyo Task Manager, ATK and SystemPanel together to make that happen manually. A better suggestion or use of them will be appreciated.
I also tried MemoryPlus and Taskkiller (The red android logo)
2. There are so many background service running some of them start with com.samsung.... (what are these?) do we need them?
3. Why some Apps always run without us telling them to run, or ask us to give them to permission to run on background at will?
ATK
In ATK in settings you have auto kill level, which is disabled on default.

I'm using JPC, ATK autokill will not able to kill at a system level like SystemPanel, so after a day of active use, the memory will still continue to reduce as some of the background service start consuming more and more memory or run more background process. E.g. Touchwiz from 17 Meg to 25 Meg.
So at the start with ATK, i will have 130Meg, after a day of active use i left with 80Meg. With Apps killed.
I use autokiller set to aggressive. memory left 152mb

free memory is bad memory!
why don't let android do it's job?! this ist linux with a clever memory management, not windows 95!!! deinstall all auto task killer android is handling the memory very well. it uses all it can get and if it's not enough it kills old uses apps from it. why have free memory, there is absolutely no reson for that! ram is fast, let the often used apps be there not on slow sd or nand!

QFT!
What is the point of having memory if it is constantly empty?
Think about it this way...If you had five friends at your house and you have five chairs, do you make 2 or 3 of your friends stand so there is always empty space or do you let everyone sit down and worry about something worthwhile?

True, upto a certain point... I don't think you need to have at least 100 or 150 mb free but it DOES seem to help to not let it get down to like 30mb...
For me:
-JM7
-animations off
-voodoo lag fix
-minfree manager set to preset agressive.
minfree manager customizes the android memory management system.
I love it this way, No lags when starting the Phone (DIALER) or anything else. The dialer annoys me the must, this must be lag free, if i want to dial i want to dial right away.
Btw, I think you have made some wrong assumptions about the Android memory management system, as mentioned, unused ram is wasted ram.

Agreed but I have never seen my Galaxy with free memory that low and I don't use a task killer. Of course I don't often have more than 3 or 4 apps running at the same time
This is not about letting ram do nothing.you surely don't wasn't your ram get used up by programs you don't want while you had no hand in this.All those services running I don't want.badly written programs that are hanging out in memory instead of closing.at least in symbian an app closed when you exited.
Why would you have 100MB free ? Do you have any application that needs 100MB to run ?! The android system already has enough memory to run so even if you could have 200MB of free memory you phone wouldn't run any faster you would just be able to lauch around 20 apps at the same time.
Read this:
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
Linux however isn’t generally affected by this. While I admit that I don’t know the architecture and reason for this… linux will run the same regardless of if you have 20mb free memory or 200mb.

Dunno, I just noticed that one time my phone was VERY sluggish and memory free was around 20mb or so. Cleaning it up did seem to help (unless one of the programs killed was causing the lag of course).
Ah well... Whatever people choose right?
You guys can argue all you want that free RAM is a waste of RAM....
But it is a fact that the SGS runs much slower when the free RAM is low. This is the experience of all the SGS'es I have tried and my own as well. At least this is the case when running 2.1. I have not tested anyone with 2.2 yet.
It s starts to lag when memory is below 40 mb. So when it s low and you start an application it starts to lag. I set it to 50-55-60 and got hardly any lag. No need to keep so much free ram

Which ROM are you using? as the low memory killer level for background apps is set at 40M which means you should have 40M free all the time or it will start killing background apps. This is also why task killers are useless, free ram is wasted ram for android.
I never had the experience that more free RAM is faster, perhaps with the stock rom but JC and upwards are all good by default. Animations off + Oneclick lagfix (or another) and the phone stays totally lag free.
Being an android user for 1,5 years now i'm very confident Taskkillers are useless except when an app is stuck. I've had periods where I used them allot but the phone only gets slower as the killed apps have to be loaded into the memory again.

Provided you are not expecting anymore friends. The problem happens if all your 5 friends are happily seated and along comes 2 more friends a-visiting. So you have to now move 2 inactive (for want of a better word) friends out of the seats so that you can accommodate the 2 new ones. This takes time. So why not move these friends out as soon as they become inactive so that the space is readily available when someone comes calling?
Try to have a read about garbage collector before argueing about free memory.
The more you try to have a large amount of memory, the more you will need major GC (and during major GC all activity is frozen).
If you let the system manage memory, it does minor GC as needed when it reaches min memory waterline (seems to be 50Mo on SGS).
Let the system do its job.
Get rid of task killer.

I completely disagree. OK, it is better to use memory, but the android memory management is extremely inefficient since it does not know which foreground and background processes are important to the user and which are not, even though it tries to figure that out. Since the Galaxy S does not allow the system to use the full 512MB of memory, this can be a critical factor. And the Galaxy S definitely lags massively when less then 70 or so MB of free RAM is available this is definitely a fact.
The biggest problem is that you cannot manually close apps and only have multitasking access to the last 6 apps used. If you use 7 apps simultaneously, the 1st app still consumes memory but you cannot even switch back to it. And there are so many useless background processes, starting up over and over again and consuming hundreds of MB memory if they are not killed in regular fashion.
Who needs gesture search, amazon mp3, layar, and all the samsung crap running in the background all the time. If you only have 10 such applications and each of them only consumes 15MB of ram, 150MB are wasted for nothing.
Every second market application registers itself as autostart on every boot, so to use a autostart manager is also mandatory.
Since everybody can easily develop for Android the application quality and resource efficiency is not always perfect. So in my opinion Android needs a task manager, this is why even Samsung integrates such a application.
Using a well configured ATK (set to ignore system applications, widgets and apps frequently used for multitasking and killing every else on screen off) and autokiller (strict setting) in addition to Autostart Manager (had to remove 40!!! useless apps from automatic startup) and lagfix, the SGS runs perfectly smooth.

Ok first of all there is something you need to understand! NEVER USE A TASK MANAGER! They are useless. Android isnt like windows, having lots of free ram does not improve performance. Infact it hinders it. The following paragraph is taken from lifehacker.
"In Android, processes and Applications are two different things. An app can stay "running" in the background without any processes eating up your phone's resources. Android keeps the app in its memory so it launches more quickly and returns to its prior state. When your phone runs out of memory, Android will automatically start killing tasks on its own, starting with ones that you haven't used in awhile.
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck."
As for the more games option. If your using the .145 firmware. You need to reinstall "moregames.apk" if your using the latest firmware. You need to reinstall "fun&games.apk"
oh i see.
ummm more games is lost because of new update?? =.=
where can i get fun&games.apk ?

See this is interesting. I just installed Task Panel and have it so it closes apps and opens up RAM every time I put the phone to sleep. I did it mostly to save battery. I consistently had my RAM at less than 50MB before the manager. Now it's usually above 120MB. My fear is battery life, and obviously performance in emulators and games like Minecraft.

[Q] Which custom ROM offers the best ram management?

Is there a particular rom which offers better ram management to allow for apps to stay in the memory longer, and cached apps get less priority?
I'm getting annoyed of apps that are suppose to be running all the time in the notification bar, but they are constantly restarting because the ram gets too low, but in fact, there is enough ram, but it's being taken up by cached apps instead!
Maybe I'm asking too much. Are there ROMS which:
1) offer more ram by being "trim"
2) manage memory better for multitasking
I really wanted to keep this phone stock, but this is pathetic! I feel that my old phone, with a "huge" 256mb ram chip was able to run more software in the background than my GN is! I've stripped all the useful apps off this phone and memory management is still an issue.
isn't the kernel responsible for that and not the rom?

Good question. I figured some roms are made lighter by removing stuff on it you don't need, and when it's done on a system level, I assumed that less ram would be needed for the os to operate.
Maybe someone can explain this?
Sent from my Galaxy Nexus using Tapatalk
I mean yeah, to a extent.. I'd believe that ROM and Kernel both contributes to it but kernel is the bigger player when it comes to optimizing "RAM."
I use AOKP + Franco Kernel if that helps. No lag problems, never even had it when it came to stock ICS. You'd might want to check your apps and see if there's a bad app causing memory leaks.

AOKP and a few other roms have the option to change the minimum ram before android os starts killing background apps. The default is about 80MB I believe. You can decrease it (do not forget to check set on boot), but I do not think it is recommended to go too low.
If you are having low memory issues its probably because of a rogue app. Install System Tuner and check for background apps that use more than ~10-20MB of memory.

How do I stop apps auto opening

The title is basically the question, im fed up of alot of programs auto opening on my android phone, it takes battery and is slightly annoying receiving notifications off apps i dont really care about such as the NFL game tells me about small things in the NFL, im in the UK, i dont care.
If you argue that it doesnt take alot of battery currently have 117mb free ram, (2 secs later) killed all my selected apps now have 201mb free so im using 80mb of ram on apps im not using. Ive made 2 or 3 phone calls today no more than 30 mins long altogether and ive lost 55% of my battery since about midday, which is when i unplugged the phone.
And I think all these apps are the problem so how can I stop them from auto opening, please help

More free RAM doesn't really equate to longer battery life or lower power consumption.
Better search for auto starts, this asp shows you the conditions an asp can turn back on and you can bin it off, Facebook for example had like 8 conditions, from full to medium battery life, on charge and change in network....... Use it

There's still no reason for most of this apps to use RAM. Apps like facebook and skype shouldn't be actice without user permission. Without login they are complete useless.
I'll try Startup Cleaner, thx.
It's how android works and what RAM is for. There is always a reason.
Sure if someone doesn't use Facebook, it should be uninstallable, but its not and its not causing any harm

The problem isn't that apps start when I turn on the phone its that even after i use task manager to close they keep reopening and use over 100mb of ram, earlier I checked and only had 78mb ram available.
This must have an effect on battery to some degree i want to kinda ban certain apps from running in the background unless i specifically tell them to

Thanks for you reply but its not really an answer its more of a contradiction, what I was asking is how to I stop apps from auto starting and eating up RAM, regardless of how long the phones been on
...and I'm telling you its a pointless, unecessary waste of time. Also it is not possible. Autostarts as already mentioned is the closest you'll get

I also turned off the autorun permissions of a lot of apps, for 2 reasons: 1) a device that is smooth sooner after booting, using less cpu cycles/power. 2) preventing Sense from reloading due to RAM shortage and have smooth multitasking.
1) Android loads a bunch of apps to the RAM that have the autorun permission, until it thinks it is "enough" and useful to you. No matter how many apps you have installed, the amount of free RAM is always about the same, just the number of "unwanted" apps in the RAM differs. Removing the autorun on boot permissions prevents the loading of unnecessary apps that will immediately be removed from the RAM the moment you start the browser/a game, saving cpu cycles=power. So for me there is no point in loading them in the first place, because I am never going to use them (right away). I want the apps that don't to any syncing loaded on demand.
2) I hate slow multitasking and I hate it even more when Sense reloads because it got kicked out of the RAM after each time I press HOME.
I use 3G Watchdog (~12MB RAM), Unlock with Wifi (~8MB), Whatsapp (~15MB), Handcent SMS (~18MB), Droidstats (~13MB), Extended Controls (~12MB), Battery Monitor Widget Pro (~13MB). Okay, I maybe could delete some of them, but these app are "OK" to me, because I use them actively or just need a background service to operate normally.
With Gemini I disabled apps like Facebook, a screenshot tool (just load when I want to make a screenshot..), various public transport planning tools, etc from autostarting.
No joy moment: after using the Facebook app (market version), it may take up 50+ MB and it will not be closed when I start another RAM intensive app, because it is a high priority service. Result: Sense gets kicked out of the RAM. Or, when the situation is somewhat less critical: multitasking is as good as unusable: switching between apps makes them load over and over again, because app2 kicks app1 out of the RAM and vice versa, causing unnecessary lag. Therefore: when I am done with facebook, I close it, then STAY the hell closed It may only autostart when it receives a push message. In that case it is nice to have FB already in RAM when I tap the notification.
Why do even some games have background services, or the Engadget app, or .. , or... all eating precious RAM. And yes, I know, once IN the RAM they eat no battery, but they DO eat battery when the app loads itself back in the RAM when it thinks it needs to, after it got kicked the moment I decided to so something else.
Hmm, spent way too much time to try to explain my frustration Oh and by the way, I have a Legend, but the basics are the same of course.
Dwnload an app called internet commander from the market. It shuts off the internet when your screen turns off but still let's you get calls and texts. I've got my phone , rooted of course, clocked to 710 and my battery will last for days.

The guys here have already suggested you use a certain program from the Market. Have you tried it?
Regarding the whole RAM consumption issue, Android has its own built-in memory management system that ensures that there's always enough RAM for an app whenever it needs it, even if the memory manager shows like 40 MB free. Basically it "ejects" all background, unused apps, from memory making room for the foreground app which needs it most. If for some reason you need to fiddle with that, you can try using the V6 Supercharger script. I find it suitable for my needs but YMMV. It's completely reversible, so if you don't like it you can uninstall it just like that.
P.S. - I agree with rootSU, the ammount of free RAM has nothing to do with battery consumption. If you suspect that an app is draining your battery, check Android's battery statistics to find the culprit.

If for some reason you need to fiddle with that, you can try using the V6 Supercharger script. I find it suitable for my needs but YMMV. It's completely reversible, so if you don't like it you can uninstall it just like that.
P.S. - I agree with rootSU, the ammount of free RAM has nothing to do with battery consumption. If you suspect that an app is draining your battery, check Android's battery statistics to find the culprit.

I respectfuly disagree. Android built in ram management is just silly. If I open xda app for example (it could actually be any app for that matter), reply to a few posts, read a few more and close it, why does it need to stay in ram? It reloads anyway when I run it again after I've closed it (using the back button or the actual exit command in the app itself). Why does the camera app need to stay in the background after I just shot a few photos and closed it? Because I may or may not use it again in some time? It's rediculous. And the whole theory that ram management doesn't require any power/cpu usage, how do you guys think all those apps get killed? Android will power?! No, kernel scans all running apps and kills the ones based on built in heuristics so it also reads them first. So that doesn't require any power/battery? Awesome if it's true! Although I wouldn't bet on that. And all this fuss just because you may or may not launch the same app sometime during the next day/week/month/year or it'll eventually get killed? Now that's just plain stupid. I get apps that need services like widgets, push notifications etc. but random apps like root explorer, xda app, titanium, youtube etc. which are opened specificly by the user shouldn't be in ram just for the sake of it after they're closed. I closed it, meaning I don't need it anymore. And I don't need the kernel to scan all apps and running services every time I launch an app so it could provide the free ram that app needs. Consumes cpu time, battery, i/o ... every piece of hardware actually just to free some ram that shouldn't be occupied in the first place. Every app that I ever opened on my phone got loaded almost instantly and that's just after phone had been booted. So after that it should stay in ram so I could open it in a blink of an eye instead of instantly? That's just funny.
Anyway, I'm just thinking out loud so don't flame me immediately. There probably are apsects of it that I didn't mention here or am not aware of. And I'm not saying that I'm right and you guys are wrong, I'm just saying what I know and think about this subject.

PlayPetepp, while it might be true that the OS allocates (thus use) some resources to memory maintenance, the impact on battery life is negligible. In the Android OS, apps in memory are ordered according to priority and state, so the OS always knows which apps to kill first if it needs to make room in RAM, without much of a hassle. The only bad consequence of this system seems to be the fact that once the memory fills up, the launcher may lag or even be evacuated from memory. But, as i've mentioned in my previous post, there are ways to prevent that, either via scripts or, if you know what you're doing, via editing system files.
So the OS doesn't need to scan anything as it keeps everything in memory again? Seems like an endless loop. Open, sort, kill if needed, reopen, sort again, kill ... to what end, constant unneccessary multitasking that user is unaware of? I really don't see any benefit of that system and am only seeing the downsides. I mean, who needs every app they ever run remain in ram even if they close them after using? And then opening another app and "waiting" for whatever needs to be closed to get it running. Sure you can mess with the scripts (init.d, init.rc, etc.) but the underlined conditions stay the same. I hope I'm making sense here. Or am I fighting against windmills.
I just figured out that I strayed from the topic of this thread so won't be continuing this discussion if it's considered offtopic.

Stop looking for excuses for poor multitasking in Sense 3+ roms

Hello again nice to see you here
Here's an interesting article on what I was talking about. Sense 3.5 doesn't need that many mbs of ram to work smoothly. After booting and setting everything up I have 150+ mb free. That should be enough for decent multitasking but all those apps not getting killed when you close them are eating too much. Can anyone explain in detail what hidden app, perceptible app, backup app and heavy_weight app means? I've been googling this for a week and can't find any decent explanation.
@PlayPetepp - I think i have already said (in my previous post) that the OS does indeed use some resources for managing the memory, but they are negligible in terms of their impact on battery life. IMHO, the only thing a 3'rd party memory manager (task killer) WILL do is improve lanuncher responsiveness (lag) as the lag does increase when free RAM drops under a certain limit. Thus used wisely, a task killer can improve responsiveness, but battery life... very little, in rare cases (it does the opposite, most of the time).
Regarding the so called "memory slots", here's an excerpt from this article:
FOREGROUND_APP: This is the application currently on the screen, and running
VISIBLE_APP: This is an application that is open, and running in the background because it's still doing something
SECONDARY_SERVER: This is a process (a service that an application needs) that is alive and ready in case it's needed to do something
HIDDEN_APP: This again is a process, that sits idle (but still alive) in case it's needed by an app that's alive and running
CONTENT_PROVIDER: This is apps that provide data (content) to the system. HTC Facebook Sync? That's a CONTENT_PROVIDER. So are things like the Android Market, or Fring. If they are alive, they can refresh and provide the content they are supposed to at the set interval. If you kill them, they can't of course.
EMPTY_APP: I call these "ghosts." They are apps that you have opened, but are done with them. Android uses a unique style of handling memory management. When an activity is ended, instead of killing it off Android keeps the application in memory so that opening them again is a faster process. Theses "ghost" apps use no battery or CPU time, they just fill RAM that would be otherwise empty. When this memory is needed by a different application or process, the RAM is flushed and made available for the new app. To satisfy the geekier people (like myself) Android does this by keeping a list of recently used apps, with the oldest apps in the list given the lowest priority -- they are killed first if RAM is needed elsewhere. This is a perfect way to handle 'ghost' processes, so there's no need to touch this part

best way to manage memory and processes

I use system panel lite to the what processes are running and how much memory is being used how can I manage this properly so I can save on resources. my phone seems like it is using a lot of memory and cpu as well
I tried system auditor and I don't think that works well at all
I use OS Monitor to monitor processes and memory usage and I use Autorun Manager to control what apps allowed to run at startup and run by itself (enable/disable recievers).
I don't use any task management app. Android OS automagically do it for you.
For more information about task management on Andoid, I recomend you to read this article:
http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
Hope it helps.
I use Android System Info (prev used it on the N1).
Has tabs for system, tasks and apps as well as 'overall'
and tracks memory and cpu%.

This. Unless you have a poorly coded app, I wouldn't even worry about it. I haven't used a task manager since my G1 days.
Unused ram is wasted ram. There is absolutely NO NEED to manage memory in android yourself, and you end up wasting battery/time/effort trying to so.
Tl;dr, android caches more recently used apps in memory, and clears memory when needed. Don't manage it yourself.

In addition to what the guys above me said, you should look at what apps are always running in the background and pay attention to the permissions apps ask for before downloading them. Many apps will rerun themselves right after being closed by task managers making it a vicious circle of death for your battery.
I use system panel paid version with monitoring enabled to keep my processes in check. System panel is by far the best method on android. I just check the history over the last 2 hours, or I check it in the morning to see what it tracked all night while idle, and its by far the most accurate and most complete picture you can get to see what an android phone is doing.

Any app that starts with priority 300 is a service and will just start back up when killed. I like to look at processes with memory usage app by twistbyte. With this you can see all apps running and what priority they are running under. Know that any app running in 300 will use battery in background.
