Galaxy S gaming performance

I thought SGX540 that's superior than iphone4 would run new games without any lags but for new games such as 9mm and let's golf 3 i've face many stutter on those games. I'd like to ask others that you have problem like me or not ? or maybe next time i'd go back to ios or waiting ice cream sandwich. Those games are smooth in iphone4 but not in galaxy s that has superior GPU.

I didn't play to 9mm and I just tested Lets Golf3, but yeah... it's not strange to have some small lags sometimes.
If gaming on the phone is very important for you I suggest to use samsung roms and not cm7 or miui.
And yeah, maybe you should have buy an iPhone, Android still can beat iOS when it comes to games

im currently on JVT.firmware

I notice the lags too. I strongly believe that the lags are caused primarily by low ram. On Froyo, I never had lags in games, and they were all super smooth. But on gingerbread, after a few hours of usage, the ram drops below 100mb, and the games will lag. The games don't lag on a fresh boot. Hence, the problem is not with the gpu, but with the fact that 512mb of ram is just not enough for gingerbread. If you want to remove the lags in games as well as in the phone interface, I recommend that you flash a 2.2.1 rom. ZSJPK was one of the best roms I've ever used.

Yeah, sgx540 is better than the 535 use in iphone 4, but it's all about drivers and optimisations. And we can't deny that Apple is doing a wonderfull job with iOS.

indeed, i also think the lags are caused by lack of ram...
when you move the camera around in the game it sometimes hangs and when the textures are in RAM, you can continue playing without fps drops or lag
a tip before you start playing:
- root your phone and install "autostarts" to disable all crap which boots up with android
- reboot phone
- after booting go to task manager and cleanup ram
- go to settings => applications => active services and kill unnecessary processes. (for example, when you close the facebook app, it still keeps running as a service, sometimes almost using 50MB ram)
i reduced lag in 9mm alot with the method above...

Is there a custom rom that has a very low ram consumption? that would fix this issues

how many ram does system take with that rom?

For games playing, 2.2.1(JSD) is a Must!

Reboot my phone. Clear memory with task manager. Kill active services... just to game? Why not just close some apps? Common sense, people. It's a brilliant thing.

Yes, it's called V6 Supercharger Script. It's like a ROM, but it's actually just a script... and you can run that script on whatever ROM you want. What it does, is it lets you pick a number. That number decides how much free RAM you'll have. Then, like magic, you just have it.
There hasn't been a single piece of good advice in this thread...

I can't use supercharger with semaphore kernel, and CF bigmem settings (98 mb) doesn't solve the performance issue.

No, custom roms, even so called simple and bare ones, use more ram than stock roms. I recommend ZSJPK 2.2.1, which has about 180mb of ram on boot, and an average of 120-140mb or ram after two days' usage.

Then you do it without the script. What's the problem here? I have over 2,000 games on my phone. And no, that wasn't a typo. None of them lag.

because android automatically closes apps when RAM is low and services always keep running in the background, whether you need them or not.
why would you let a service use your ram when you don't even need it? THAT is common sense.

bigmem kernel may help? its what i use

I've rolled back to froyo and now without apps in the background i0ve about 140mb of ram used, and now 9mm goes smooth. I'm not moving from froyo any more.
Also, now the battery lasts in 6 hours of screen usage, and with jvt only 4 hours

Are they though? When I help someone out, I tell them correct information. If I don't know the correct information, I don't tell them anything. Why? Because incorrect information is worse than not helping at all. Few people in this thread have given remotely acceptable advice. No one needs to do a 3-step process, including rebooting your phone, just to play games; likewise, no one needs to downgrade to Froyo in order to game either.
I have Let's Golf! 3D installed currently, but I don't have the most recent revision of 9MM—although I have played it in the past. I have my phone's CPU and GPU overclocked, like I'm sure many of us do here, and I can play both without noticeable lag. I didn't have to reboot my phone to play them. I didn't have to uninstall apps to play them. I didn't have to flash an entirely new ROM to play them. And I certainly didn't need to stand on one leg with the phone above my head to play them.
Bad advice is just bad.

I posted what helped reducing lag in 9mm on my phone.
if you don't need the help i posted, that's too ****ing bad. the fact this topic was started shows people are facing the same problem with lack of usable ram memory for 9mm.
looks like you have some sort of magic phone with unlimited amounts of ram memory that never lags
the reason why i told him to reboot his phone is because ram usage is much less in most cases, right after booting up.
and btw, next time do some more effort instead of posting one line if my information is not correct

[Q] Galaxy nexus gaming ridiculous lag

Hi there
I have a Galaxy nexus on android 4.3 and running 3d games have lots of lag. For example, the game with the most amount of lag is Modern Combat 4 with the meltdown update. Is there a way to improve the gpu processor power on the phone so that itwouldboost the framerate? Its always about 5-15 fps and im so annoyed. If there is a solution, could you let me know? My galaxy nexus is not rooted.

Does it plays smoothly then, for no reason, it gets laggy for some seconds, then come back to play everything smoothly again, then repeats? Or it just keeps being laggy at all times?

It does exactly that, it plays smooth for 5 seconds then ridiculous lag for 10 seconds then repeats like a loop.

What I'm gonna tell you now may be related to what what is happening with your device or not. It was my problem, so if it's not this I don't know what can be happening.
First, the galaxy nexus can downvote it's processors when it's too hot, although it's probably not that, just keep that in mind.
Anyway, go to settings - apps then "running apps" and check the used and free ram. If you have high RAM usage (like, 600 mbs being used) than this is probably the problem. While you're in the game, your gnexus will try to clean RAM for it, but since your gnexus is already out of RAM, it will force close background app's and services, but since those are required to run all the time, all that's going to happen is that they will keep being restarted, causing lag in the apps that are running.
To check if this is the problem, just check how much free ram you have free. If it's too low, open a game (even temple run 2 or sub way surfers will do), then when the game starts, go back to settings-app-running apps and check for things restarting.
If this is the problem, then you need to see what is the apps that are consuming all your RAM (although it can be android itself, just keep reading).
Just check what apps are in the running part of the "running apps". If you have a lot of apps running, then you can try freezing some of them or unnistalling the ones that consume more RAM. BUT! it may be that there's just too much RAM being consumed even though you have few apps running, in this case, the problem is android itself.
I don't know if this happens to android 4.3 itself, the gnexus's version of it or if it's some app causing it, but there's a memory leak that will eventually consume all your RAM. I'll use my case as an exemple: I have some common apps running on background (facebook, messenger, whatsapp, airdroid, 3d watchdog). If everything is normal, my "used RAM" keeps aroung 430mb~. Leaving almost 200mb~ free for apps to use. But after some days using my phone, the used ram will grow to 500, then 550, then 600mb, eventually to 630mbs.
Check if this is happening to you. To check, simply reboot your device, then when it boots, check how your RAM is being used.
If it was normal before the reboot (around 500mb, probably even less) and stay this way after the reboot, then your problem is another one, then I can't help you.
If your RAM was high and after the reboot it's still high, check your running apps.
If it's high but after the reboot it's back to normal, then you just "solved" your problem. Just keep rebooting daily.
If this was your problem, then enjoy your phone. If it's not, you can try checking some other things like the I/O speed (which was solved in android 4.3. Check this thread http://forum.xda-developers.com/showthread.php?t=1971852&highlight=trim ).

When I checked, I had about 300-400 megabytes of ram being used. Thank you for the info and the effort though. It has a dual core processor, it should be able to run well.

I figuare out the problem of the game lag, the CPU temperature limt!
If you're using custom kernel, set the limit to 74, and u will find out it smoothly on game play, plus if you of the gpu to 384, its almost lag free, but frame drop is also here coz the gpu power.

Does this work on stock kernel also? Last time i had custom kernel, lots of screen problems.

Nope, flash leankernel, wipe cacje and dalvik cache, install trickster mod, and adjust the settings.
Quite less you can do with stock kernel.

You need to use trickster mod not Franco app. The Franco app is optimized for the Franco kernel.

FKU also incorporates LeanKernel Updater so why isn't it optimized
And just to add that the above trick of disabling thermal throttling works nicely for me. I always wondered about why playing PPSSPP produces random lag - setting the governor to "performance" won't help a bit - and FKU saved my ass!

Best battery life and performance.

Hey all. Just wanted to get some input on getting the best bang for your buck when it comes to battery life. Though I've never been one for task killers and battery saver apps, recently I've been testing out a few different apps. Avast (uninstalled as I've never seen the need for anti virus on Android personally), Battery Doctor, CleanMate (I think It was called) and a few other battery saver apps. However, I cant seem to come to a conclusion on whether they help or hinder. Or if I'm even using them right.
The thing is they all seem to tell me different, conflicting info so I can't really make heads or tails out of it. They all seem to tell me different apps are running in the background and all suggest I do different things like kill apps, clear cache, free up memory, etc. What I have always used is system panel to kill a malfunctioning app if needed, cachemate, and SetCPU to underclock when the device is not in use. Now I am on a stock ROM with root and dont have a kernel that supports over/under clocking.
So I was just wondering what any of you guys to to both increase performance and save battery. Some kind of balancing act. And I don't want my experience to suffer, ex- I like my screen bright so am not going to turn it down to 30%. Stuff like that. I am kind of with the thinking that I should just use my tablet and let the system do its own thing, but then I kinda get that ocd thing going and want to have total control. So anyway, would love to hear what you guys think and use. Also, i would love love love to try out tasker but am unemployed and broke so that cant happen anytime soon. Thanks.

Out of curiosity, how long does your Note 8.0 last?

You know, I couldn't really tell you right now. I inherited it from a friend about a week ago. He thought it was bricked and junk. I just loaded up some stock firmware, rooted it and since it's new to me I have been playing around with it lots so haven't experienced "normal use" yet. I wasn't really asking because I thought the battery was bad, but I just like to have total control and wondered what everyone was doing these days. I used to be big in the android scene, as a power user not a dev or anything, but have been out of the game for awhile. So far the battery seems to be really good when it's on standby or say if I have spotify running or netflix or playing an audiobook. But it seems to drain pretty fast when im using it more actively- emailing, switching to facebook, switching to internet etc. Again, I'm not really having battery problems, and it's a new tablet to me, but I just wanna stay ahead of the game. Sorry I can't give you any numbers right now, but I'm sure you understand.

Do a search about battery.. there are a dozen threads in the Q&A thread.
I am a minimalist and don't like any so claimed Battery Booster, Battery Enhancer, or Battery Calibrator apps that are all over the google play apps site. Most of the time I leave power saver on, and have most all sync settings and apps set to automatically update and poll info and retrieve email. As I do not like to jump through hoops to get some thing to operate as expected.
Security 360 does a great job with antivirus and memory consumption with apps. You may think that you may not need an Antivirus, but this one thoroughly checks apps if you decide to turn off Google's app checking, or use private party apps from forums or developers linking them to sites.
I use Xposed framework, mainly because of the ability to turn off functions without needing to install a custom ROM. I have been there done that and am not impressed with custom ROM of any type, over stock.
Turning off DVFS, thumbnail cache, and leaving Boost Mode alone as it is defaulted off... Is my primary setting with Winam Xposed module.
I use the app Greenify, Substrate, and its experimental plugin to Xposed. It has some nice features to complement Security 360.
Since Google has corrected some issues with some of its apps, and a few other apps have updated recently. I get 2% drain with 12 hours of standby.
Also under normal use, I get 8 to 9% drain per hour, and 6% per hour browsing.
For speed improvements, I have a 633X SD card that has been tested around 93MB/S and 44MB/s write on my laptop, there are some rated double but are about less in real life performance.
I use TweaksterMod Pro from my past custom ROM experiences, only to boost read a head cache to double the default. This only helps with super fast SD cards, the slower the SD card or having congested internal RAM the boost must be greatly increased.
With online video and media, I get about 12% per hour drain doing both streaming and miracasting to tv.

update to 4.4.2 and battery calibrate resulted in 30hr+ battery life
good to read from you andr0id23 and gooberdude. I'm a little sensitive from my battery. since I bought two n5100 for me and my sister,I compare them in many aspects like performance,physical keys (volume,home,..) quality,battery life,... first I thought there's a problem with my battery.I used to test a lot of apps (some you mentioned,battery doctor,task killer,clean master,..) on my 4.1.2 stock ROM.the result was disappointing. my note hardly lasted for 8 hours with normal use (browsing,email checking,no games).it was better on my sister's tablet.
so I updated to 4.4.2 stock rom. things were like before UNTIL i did a battery calibrate.using a method almost like this link.by deleting battery stats after full charge.
I've attached the result.
notice that i have done a full wipe before update and i don't have that tones of app from 4.1.2.only the stock bloatwares and 25 harmless apps and games.this is the best result.the battery was so stubborn to live on its last 3 percent. approximately 3 hours on 1 present and the turned off.

misunderstanding some terms

OK, if you rooted...
I recommend getting Xposed Framework installed, then install Wanam Exposed. It has a ton of mods to adjust about anything. Though depending on model and firmware, some stuff wont work.
If you want minimal... you can get Wanam Disable DVFS... Samsung's Touchwiz has a feature to assist with games called Dynamic Voltage File System. It seems to be the root of the evil with samsung devices. Google has made it clear that battery calibration tools don't do anything to calibrate the battery. By clearing the battery stats file, all you are doing is a temporary patch. DVFS does not play well with Androids battery stats, and corrupts the data for stats, thus giving bad battery status. Once DVFS is disabled, android will properly calibrate the status of the battery. It may take a few charge cycles or manual deletion of the battery stats file and a reboot.
Again if you root, you may want to add RootCloak to allow apps from detecting root. It does it automatically once you select the troubled app. It requires Substrate and allows you to click on a link to install. Once substrate is installed it will allow rootcloak to function properly
Saferoot.zip search for it in the note 8.0 threads... I placed my copy as a file in one of the requests.
It will allow a proper root without having to flash. So no need for triangle away unless you plan on a custom ROM.
If you use saferoot, you can always upgrade to 4.4.x at a later time without having to unroot or do any trickery.
Play is messed up... never worked right on my tablet, both with stock ROM or custom ROMs
Play music does not like a large amount of media on SD storage, let alone full Mp3tags... can't handle the data or just too many files.Also music does not stop when you reboot. after some time it starts up and plays again. Gallery is messed up with image caching. So I used Wanam to disable scroll cache. I use Nokia Music Player as it is the most robust player that is small and works well on a tablet.
Freezing google music will keep battery consumption down if you have a lot of media. as I have over 4,000 files and if any one of them has an odd character in the name, the media server goes ape and cycles a lot of CPU time into trying to index. Thus sucking power like it is cheap gas.
My sig shows what a stock ROM is capable with just a few add on apps to help get things sorted out with battery power. Right now I am in a fight with Security 360... they boogered up the app with Soccer Ads in splash screens during boot and starting the app. Other wise it is an excellent app for what it does. I use it to clean out krapp that usually is not monitored by other cleaning apps, and to tweak boot blocking apps and apps that are running in background after wake up.
Greenify works fine but you may find security 360 an added app cleaner for sleep / wakeup cycles.

great user
mmm.it worthed more than a simple thanks to me.
by the way you use it in a good way.it s about 1gb of used ram on start up for me.and 970 when killed processes.
I'll try those you mentioned.seems very usefull

Gallery is messed up with image caching. So I used Wanam to disable scroll cache. I use Nokia Music Player as it is the most robust player that is small and works well on a tablet.
Freezing google music will keep battery consumption down if you have a lot of media. as I have over 4,000 files and if any one of them has an odd character in the name, the media server goes ape and cycles a lot of CPU time into trying to index. Thus sucking power like it is cheap gas.
My sig shows what a stock ROM is capable with just a few add on apps to help get things sorted out with battery power. Right now I am in a fight with Security 360... they boogered up the app with Soccer Ads in splash screens during boot and starting the app. Other wise it is an excellent app for what it does. I use it to clean out krapp that usually is not monitored by other cleaning apps, and to tweak boot blocking apps and apps that are running in background after wake up.
Greenify works fine but you may find security 360 an added app cleaner for sleep / wakeup cycles.

have a look on this topic.it for galaxy tabs but I guess it works on Note 8 too,although it is on your own risk(seems no risk,nothing gets worth than current state )

additionally,as I'm searching on batteries a few days,i found that there are different fuel chips out there.so we must do fuel gauge calibration method that fits our chip.If you found that please describe it here.

Android Oreo (8.0) performance issues

I'm experiencing lot's of issues with the latest Android update.
Firstly I made an clean install. My System, Recovery and Bootlader is all stock or anything else got modded.
My RAM is always 99% used.
I have only Messaging apps and Media apps installed. (i.e. WhatsApp, Telegram, Allo, Hangouts, YouTube, Spotify)
So here is my issue:
My apps won't stay in the RAM.
If I write a message in Hangouts and than switch to WhatsApp, immediately switching back to Hangouts will cause this app to restart.
This is happening to all applications...
Btw app startup takes 5-10 seconds and unlocking the device with my fingerprint sensor takes also 5-10 seconds.
I made a factory reset twice. Nothing changed...
Do you expereince the same problems with Android Oreo or is it running smooth for you?

Updated to Oreo since day one. Yes, ram do stay at 90-95% at all time. My fix was simply using greenify with root of course and put everything to hibernate except for the very important stuff like IM and Mail app. Now it's back to the standard 70-80% and I'm pretty happy with it.

A much better solution would be to limit background processes which can be done in Oreo manually but is normally done automatically anyway.
Keeping apps in RAM and letting the system do the memory management is a great idea, manually force closing apps (which is what "hibernate" does) just removes it from RAM and sure, you'll have more free RAM but what are you going to use that for? To reload the same apps back into RAM again which is much slower and drains more battery.
Your RAM should be as full as possible, free RAM is wasted RAM.

That the RAM is full is great, it shows that it's working as intended. That apps won't stay in RAM is a problem though, one that I don't have.
Battery life is about the same for me while the multitasking/memory management/background process limitations/performance is much, much better.
I just OTA'd it without wiping anything.

So if I run 10 apps in the early in the morning, and then only want to use 2 apps throughout the day, I should keep the other 8 apps so it would load faster the next time? But then due to the lack of ram, every time I'm trying to do task switching between ONLY those 2 apps, I MUST wait for a reload each time? Your logic checks out mt professor. I should've used an iPhone instead.

Yes, you should keep them and NO, it doesn't work that way.
Your phone keeps the apps that are used and swaps out (ZRAM until that's full then back to disk) or flushes those that are not, the most recent apps are the ones that are prioritized and kept in RAM so your two apps will be kept in RAM at all times unless they are so large that one is swapped out but in that case "cleaning RAM" won't make any difference.
It's not my logic, it's simply the case that I know how memory management in Linux works and you don't.
BTW, the memory management in the Mach kernel (originally from FreeBSD) that IOS uses works exactly the same.

I'm having the same issues.
I made a fresh install of the Factory Image, and then flashed the OTA just to see if it helped any when it came out.
Going from any app to the home screen takes about 5 seconds, and you invariably get some time to stare at the blank wallpaper before the icons pop in several seconds later.
Starting up the camera takes probably as much. Trying to take a lens blur photo is hell, since the scrolling is all choppy.
Starting Chrome takes ages. Same thing with Facebook.
It often happens that I'm listening to music on Play Music, and I go to Facebook then task switch to, say WhatsApp, and Play Music dies.
Also nice when it happens with Uber. Ask for the car, answer WhatsApp and 10 minutes later, why isn't the car here? Surprise. The Uber app had died.
Using the Share dialog is also hell, and so is the Photos app.

Running better than Nougat here.
I have generally found that starting from scratch every major update is the way to go, instead of doing OTA updates.
Android is an open platform that allows you to customize in a lot of ways. The trade-off is you can often get rogue apps / services running in the background sucking away performance and battery life without you realising it (unless you use Better Battery Stats etc. Still, even then things can sneak under the radar).
Every now and again wiping everything and starting fresh can make your device seem like new again. The standard Google backup service is getting pretty good now as well. Combined with the new Google auto-fill service I have now ditched apps like Titanium backup completely. (Google is now backing up SMS's for you, which is a massive win).
I am using a few tweaks which is probably worth mentioning:
* EX Kernel - Glassfish 1.2 governor profile
* Magisk 13.3
* Greenify - systemized with Magisk
* Oreo Pixel mods
Using Magisk allows me to have root and still make Safetynet pass, which ensures Android Pay etc. can still be used.

Are you using stock ROM ?
I did a full wipe but the system was very laggy compared to Nougat. Maybe EX Kernel can optimize that...

Yes I am using the factory images.
I don't think the EX Kernel will fix a laggy system. It will improve battery life but you won't see massive leaps in performance or anything - the stock kernel is still pretty good!
My guess is one of your installed apps is probably doing something weird.
You could try completely stock (don't install any apps) and see what the performance is like.

Thanks a lot!
I'm no rooted using Magisk 13.6.
I'm also using Greenify (PlayStore Version). Systemized Version (via Magisk) didn't work. (Crashed during setup). But the PlayStore Version is working fine.
I'm having the best performance I ever had with my device.
Why is Google releasing such a broken version?
Finaly what Oreo Pixel mods are you using?

Upgraded to v8 and now system performance is terrible and many FC's. It seems this release was not ready for prime time or Oreo will require more than 2GB of RAM for a functionable experience.

One of the most annoying things are these notifications that Facebook Messenger is running in the background and you can't get rid of them.

Here is a fix for that: https://www.xda-developers.com/hide-app-running-background-notification-android-oreo/

I have alot aof Lags with Oreo. Slow opening the camera and shot an Photo. Poor Performance when i using some Apps like Facebook, Google Plus and other. I just downgrade to Android 7.1.2.

Performance has been awful for me. Always stuttering and freezing up. I have had 3 Nexus phones (Nexus One, Nexus 5 and Nexus 5X). I've gotten many make major updates. The update to Oreo has been the worst by far. And the battery life has shown a large decline.

Clean flashed Oreo last night with the latest SuperSU/ElementalX/3Minit performance has been excellent; battery has been ok.
Here is the order in which I flashed:
- flashed stock via fastboot
- wiped userdata, flashed ElementalX (to unencrypt)
- booted, finished setup
- disabled most of Google's bloat (drive/Google App/TTS), updated internal GApps
- rebooted into recovery and flashed SuperSU, booted in (installed MinitResources) and rebooted back to recovery
- flashed Surround Sound/Aroma tweaks (3minit/Pixel Navbar)
- disabled A57 cluster (GhostPepper for small cluster), underclocked GPU to 367MHz, disabled KSM/ZRAM
- Buttery smooth even with a 60fps Nexus live wallpaper
:good:

My experience:
Battery life was great , apart from a drain when gaming, but I don't game so I didn't care
RAM Management - I know what you mean, my RAM was 1.8 GB consistently
Speeds - No consistent problem apart from games again. When gaming, my device would freeze and go jaggedly. :crying:
Fingerprint Scanner - 1-2 seconds to unlock
But alas, I installed TWRP and got a bootloop....

That was me with Nougat. There wasnt a 7.x.x update which didnt bug my phone.
7.0 - Battery
7.1 - Battery, Bluetooth, WiFi
7.1.1 - Battery, WiFi
7.1.2 - Battery, WiFi, Bluetooth, Charging Decline
8.0.0 - Cannot handle gaming
8.0.1 - ???

I flashed the factory image, but I'm running into serous memory issues as well.
The biggest problem is that it's a toss-up if taking a picture will kill my music... Taking 2 pictures in a row will kill the music 100% of the time. I've tried turning HDR off, but I still run into the same issue every now and then. If I try to take a picture while using navigation and listening to music; it will hard crash. Not only will music and navigation close, but I will loose the picture AND my homescreen wallpaper. It will crash to the homescreen and reset whatever image or live wallpaper I have to the factory pink mountain image.
I've also had music crash when trying to send an MMS too... Multitasking just seems to be a nightmare after Oreo. My original plan was to move to a three year cycle when buying the Nexus 5X, but I doubt it'll make it another full year.

[QUESTION] Apps being killed

Hello.
I got a Mi A2 Lite a few days ago, is my first Android One. My model have 3Gb of RAM.
I'm facing the following problem:
Let's say I'm playing Lords Mobile (the only game I play). Then, I receive a message on WhatsApp. I go there and reply. I then go to Facebook and/or Chrome to check something, and want to go back to Lords Mobile. The game was pulled out from memory, and need to reload again from zero. Same with Chrome, it shows all my tabs I had opened, but is surelly reloading again from zero. Is like the "clear all" of 'recent apps' on some other phones.
I think 3Gb of RAM is enough to handle these apps, don't? I don't have too much apps installed, and the memory use is about 2Gb. I don't know if this behavior is native, by the way. Another example: if I go to sleep just after play, when I go to game again in the morning, the game reload from zero.
Is this normal? Any way to make this model handle the memory in a better way, if is the case?
My device is on Pie, July security patch. No root.
Thanks in advice

It gets better over time. There is "AI" that figures out what to keep in memory.
But in general, pie seems to be worse than previous releases at keeping things in memory, even when memory is not full.

Not that anyone seems to know. Maybe custom ROMs help?
I just used my phone like normal and noticed that it got better at not unloading apps that I came back to regularly.
You can try to force Android Go mode, since it's designed for really small RAM use but I tried it and didn't like it (changes some things).

It's not AI, it's the Kernel's scheduler profile, and Xiaomi is famous for tuning it with an aggressive policy towards keeping as much RAM available as possible. The only way to improve it is by installing a custom kernel.

Well, custom kernel and ROMs means unlocking bootloader... I can't do this for now. But, anyway, thanks!

3 gigs of ram is barely enough for pie. On the 4 gig version I have barely 1 gig free at idle. But mostly, the app kill is done by a crappy A.I. system that does some battery optimization.

Well, taking in note what @slimshady76 wrote above, maybe the "Butterfly for daisy" will be a good deal. But I can't do it now.

I just made a test on last 2 days.
I uninstalled any optional app on phone I downloaded, and disabled a lot of system apps. Lords Mobile won't unload from memory when switching and/or when I sleep and back to game at morning.
So, is a lack of memory, but I still thinking 3Gb is enough to handle it. When 10.0.12.0 comes available to download, I'll try Butterfly kernel.
