[Q] protect apps to prevent lag

Hi
I have done the 1-click lagfix that relies on ext2.
I have also installet autokill (the one that changes the internals of the system)
I have 2200 point in qualcom.
STILL I have massive lagg now. It started out well after the rooting, but now its worse than ever. In fact I have even failed to answer a call due to the lagging.
(I have installed Tasker and have 4 tasks set up, i really hope this is not the reason because I would really miss tasker)
I can notice a big differense if I start the dialer and press Home istead of Back. Assuming Back actually kills the process? If I use Home, I can bring it up again in a split second. Using Back and it an take everything from 300 ms to 4000 ms.
I have now started to experiment with Launcher Pro (who some claims to be faster) but this is actuall just a shell and I cannot dedect any differense.
I have tried different presets in autokill, but since this lag is probably not due to lack of memory, i have now set it to "system default".
Is there a way to keep important processes in memory all the time? Like the dialer, contactbook, sms etc? I dont really care if it takes 500 ms longer to start up google maps or facebook, but the PHONE FEATURES must work properly on the phone.
I run a stockrom JM2

hello, as well as the lag fix, I also disabled ui animations and installed autokiller set to strict or optimum and the lag is now minimal for me, it's still there at times but not as bad as you describe.

ironicly i didnt have this problem before lagfix/autokill. It was there so i decided to run the fix (and the qualcom-score is always cool i thought). But now its worse.
Does anyone have experience with tasker as a performance-killer?

[Q] S4 9505 - suddelny slow / stuttery - any hints? [solved]

I have this weird problem with my S4, that just surfaced yesterday. Overall it just feels a little slow and laggy. For example the home screen left-right-swipe animation looks like it's rendered at ~10 fps, same with scrolling lists. I know for certain that this was better just a few days ago.
What i'm running:
- Stock Rom (XXUBMEA) + Root
- Some apps removed (Widgets, some Samsung Apps, some Google Apps)
Things i recently tried / changed:
- I just installed tasker
- I used Titanium Backup for the first time
Things i already checked:
- There's no energy-saving setting enabled
- There's nothing running out of the ordinary (Settings / Apps / Running)
- System-Load is not outrageous (around 2.0 for 1m, 5m and 15m)
- I deactivated tasker and titanium (see below)
- Rebooting does not help
I am mentioning Titanium Backup, because this is probably the most invasive thing i did to my phone over the past 1-2 days. I did a full "Backup user apps and system data" run, after which my wallpaper was missing and my keyboard was reset to the Samsung one. Also, the clock on my lock screen (stock samsung) didn't run anymore (though this was fixed by a reboot).
I hope any of you guys can give me a pointer in the right direction. Right now, i don't really know where else to look.

solved: Samsung Push Service made things very slow.
Well, that was a short first introduction.
The answer was indeed already in here:
[Q] Samsung S4 somewhat sluggish and slow?
I just uninstalled Samsung Push Service - and it really seems to solve the problem?
I wish to apologize by the people developing Tasker and Titanium Backup for even suggesting that this could have been their fault.
Anyway, thanks for reading. Maybe this is still useful to someone googling the issue in my words

battery life with resolutions

I have not seen real comparisons yet of battery at all 3 resolutions. Has anyone tested? I'm running at the lowest today just to see. Honestly screen is fine and can barely tell the difference at lowest res

curious for this as well. Got fairly good life out of it with factory settings at 1080. Switched to 1440 last night and cant really tell a difference in resolution but i think battery life is hurting.

EDIT: Tmo S8 with update, for reference.
Because I also couldn't tell a difference, I immediately switched to the lowest resolution. With the following settings, I had 92% battery left at the end of a work day where I would have had about 60% on the Nexus 6p:
- Brightness always at max and disable auto brightness. Bluetooth on, WiFi off.
- Disable pretty much every Samsung feature, gesture, and Samsung app. Made as Nexusy as possible (still using Samsung launcher, which is fine, and I uninstalled Google because I don't really use Google Now and suspect it's a battery hog. The only voice feature I was using was "ok Google navigate home", but now the maps app just let's you save directions as home screen shortcuts).
- Going through the permissions settings in the advanced app options menu in Samsung settings, I disabled all permissions for each app except the ones I know they need.
- Installed Package Disabler Pro and blocked a **** ton of stuff, including in the system packages. Anything with the word bixby in it, all of the T-Mobile apps except visual voicemail (anyone know if I can disable that and still get visual voicemail via the Samsung phone app??), and most of the Samsung apps except things with the word clock or calendar in them because I assumed the overall ROM relies on them but I could be wrong.
- Once done with everything, close all apps then go into settings > device maintenance > optimize now, then reboot the device.
- This CAN have VERY good (potential) battery life, better than the Nexus 6p when reviews were suggesting it was pretty bad.

Kind of, but not entirely.
It has a section for verified safe-to-disable apps. If that isn't enough, there's a section for "system" packages where I avoided disabling anything that I want pretty confident wouldn't affect the overall system (like I didn't disable anything that has to do with sound or audio for example, even though a few of them looked like bloat). I'm the system section however is where you can disable bixby and carrier related ****. There's a search section, which is very helpful (e.g. search "bixby' and disable everything).
I have the advantage of having messed with phones and done trial and error with a much less organized app that essentially does the same thing, which has always been very popular for topped devices, called Titanium Backup.
Finally, when you're done blocking everything you want to block, hot the menu button (top right) and clear the data of disabled packages! VERY good app overall in my opinion, beat $1.50 spent in a long time!

[FIXED] Push Notifications Not Reliable on the S8/Nougat

Upgrading from the S5, Chrome Push Notifications were almost always instantaneous, and I never once missed a notification. On the S8, many are delayed and I miss a huge number of them, mostly when my phone is "off" (eg, in my pocket). Anyone else experiencing this, or know how I can fix it? The only thing that has changed is the phone, so it's definitely something with the S8 (or possibly the kernel version running on it). Seems to happen on both wifi and cellular network. I need these notifications, so any help would be greatly appreciated. Thanks in advance!
Update: Here is how to fix the issue of not getting notifications for an application on the Samsung S8, or probably any Nougat device:
Go to Settings -> Apps
Click the : Menu in top right, select -> [Special Access]
Select > Optimize Battery Usage ->
Click the dropdown menu towards the top of the screen that says: "Apps not optimized [v]" -> change to [All Apps]
Add any application you want to get notifications for without delay, all the time. Eg, Chrome, Gmail, Facebook, etc.
Hopefully Google will fix the overzealous battery optimizations soon so we don't have to do this!

Oh boy. I love the phone, but something in the RAM and Battery optimization is killing all background apps, including your Chrome. Drives me nuts, every time I switch between apps and return to previous, its restarted, which means forgots to where I was. Very annoying when reading news, Facebook etc. Seems like there is no fix for it at the moment.
Excluding apps from battery optimization doesn't help at all. Everyone think is Nougat problem, but my S7 edge didn't have the same issue.

I thought I'm the only one with delayed notification issue. I tested the gmail notification on my s8+. The phone was in standby mode on my pocket and I sent the email from another account. No notification until 4 minutes later. With my other phone notifications are instant. I have issues with other app notification as well. The forums apps will not even notify me anymore if someone responded to my post.

It is definitely related to some overly aggressive battery/cpu/ram optimizations on this phone. I also have seen weirdness in other apps, like you guys mentioned. However, one exception is AquaMail, which when I set it back up on this phone during install, it explicitly asked me to click a thing that took me to some deep setting that allowed me to excluded AquaMail from some battery or some other optimization. I don't remember, unfortunately, because I was just trying to get my phone setup, and didn't think it'd be such a widespread issue. I'll try to dig around and see if it still shows a way to get back to that setting, or if there is a way to add other apps while IN that page.
I also have the battery optimization thing to "Off" and it's not monitoring apps (so it says). In developer settings, there's a background apps setting, default is "standard limit", whatever that means, but the largest choice is 4, which seems really small...
This is definitely frustrating, I love the hardware side of this phone, it's amazing, but the software/OS execution seems like a huge miss, almost like it went completely untested live. Hope either they fix these issues soon, or someone figures a way to do so.

The interesting part is that I have too under Battery: Power saving modeto OFF, but that doesn't stop the phone still to put apps to sleep. An hour ago I had a notification that 13 aps will be pit to sleep, even that I have power saving mode to off.
It is very annoying: if I have clicked form something(web page or Facebook, Upday etc) to a link and start reading, but in the mean time I have a message and open it to respond, when I am back to the first app with the open link, it gets reloded to the original page as I have never clicked on the link. Facebook is very good example.

I can't even seem to figure out how to get to a RAM usage screen in settings at all on this phone. I'm curious if it's something sucking down all the RAM causing apps to swap on/off, or it is just an aggressive optimization setting somewhere.

Sounds to me like a Nougat issue rather than anyhting to do with this phone. This is exactly the sort of thing that has worried me constantly since i first heard about this kind of battery saving feature they decided to implement in Nougat.
Have any of you been using Nougat on your previous device without having this issue? If not then I would say it is probably Nougat causing it.
I have similar with bluemail where sometimes it doesnt notify me of hotmail emails very quickly but i put that down to bluemail being a bit slow sometimes since it did it on my S5 too.

This is my first experience with Nougat. stoyank said his S7 on Nougat did not have this issue, fwiw.
I'll take reliable apps over better battery any day of the week. This is pretty ridiculous, and even more so since there doesn't appear to be a way to fix/turn it off!

Update:
Found the settings page:
Settings -> Apps -> : Menu : Special Access -> Optimize Battery Usage -> Apps not optimized [v] -> All Apps
On this page almost everything is listed as "on". I scrolled through, turned Chrome, Chrome Device Library, and Google Services Framework OFF. No idea if this will help, but hopefully it will.
Will let you guys know later today if I missed any more updates. There might be another service needs turned off on this page that I missed. If you're missing updates in one of your apps, try turning that off in this page, and see if it helps. I'm guessing and hoping it does work, because AquaMail was one of the few things listed here as Off (from my config thing I did when I setup the phone) and it always receives emails instantly through push.
Update 2: My wife's S7 apparently has this same issue since it updated. She often doesn't receive facebook notifications since it updated her phone to nougat. She just assumed it was the facebook app that was bugged. Yikes! Not sure how this hasn't become a bigger issue, surely there are tons of people that need reliable push notifications for various apps. Hopefully my fix above works as a band-aid until a broader fix is implemented.

My Galaxy s7 edge was updated to Nougat for good few months before I got the S8. However I have not experienced similar issues. Most of the apps did not need to reload every time I switch between them. I am not bothered about getting an email a couple of minutes late, but browsing news, or wifi streaming music to an external player is non usable at the moment. It looses conection, reload pages, every time I scroll down on Facebook and swithch between apps, it seems as it goes back to the top of the news feed, loosing where I left it.
A week ago I was watching on YouTube a comparison between iPhone, S8, pixel and some other crap, and surprisingly on a speed test and re-opening the already open apps, the Galaxy S8 came as last as it seems that needed to reload all apps again. You can imagine​ the shock I had, since I don't like iPhone, but it came first, nearly twice faster.
Need a fix soon, as I already give my Galaxy S7 edge to the wife. Can't get it back.

Try my suggestion in the post above yours, see if that helps. So far, I haven't missed any notifications, but it's too soon to tell, and I haven't had my phone in my pocket, but on my desk.

I know you can cherry pick some apps and exclude them from being monitored, and power optimised. However, not all apps are listed under "+add apps" for example Chrome, Upday, Facebook and many more.

Thanks for that. I knew I have seen those options ony Galaxy S7 but struggle to find them on S8( I know how stupid sounds that). I was looking inder wrong menu(battery). Will monitor for a day or so and will see how the phone behave.

No problem. It was in a weird spot. Seems to be working great so far, I'm back to instant notifications, something that wasn't happening before. Will give it a few days til I call the all clear.
Still annoying we have to do this at all. Hope Google gets it fixed. I saw people complaining about it back in August, so I'm not too hopeful of anything immediate.

I would say my fix works. I have received every notification in a timely manner. Updating the first post to reflect this.

I resolved my gmail not in push mail mode by simply removing the re-adding the accounts.

I did that on Google Inbox app as I have issues getting any email notifications. Still not receiving any!
I deleted the app, deleted cache, put it as priority, removed from optimize battery list, everything! Still no notifications for email via Inbox! WTF

Posting just to say I already have made sure gmail isn't being put to sleep but I'm also not getting mail notifications reliably on my S8+. Missed work emails on more than a few occasions by hours because of this.

Ok I was able to fix it finally by: Deleting Google Account and re-adding again.
Email (Inbox app) notification work now

How to disable/adjust the background task limit?

My background with android is long and rocky.
A long time ago in a galaxy far away, I had a Samsung Galaxy S, then a S2.
I can remember a Google Nexus phone in there somewhere.
Then at some point I switched over to Windows Mobile for many years.
A couple of hears ago I came back to android with a Samsung Galaxy S8+ and I hated it.
Recently I upgraded to a OnePlus 6T McLaren and here I am.
I had been expecting to see android happily use up 7, 8 or even 9GB of ram before the background task manager would begin to kill tasks.
Except that I seldom saw android use much more than 5GB of ram.
And worse, background tasks were being killed on a regular basis.
Widgets would stop working overnight, or even in just a few hours.
Spotify would close while a playing a playlist.
A quick search on XDA reveals that many users believe that Android will just use up as much ram as your phone has.
However, that is simply not true.
And so, I began my quest to have Android use as much ram as the phone could provide.
In my case, 10GB.
- I understand that there is an inherent trade-off between keeping background apps running and battery usage. I can live with extra battery usage in exchange for keeping my widgets running or Spotify running for an entire playlist.
- I realized very quickly that in order to achieve the results that I was looking for that the phone would have to be rooted. So rooting was one of the first things that I did.
Step 1.
I started with the basic stuff that a quick google search would provide;
- Settings -> Battery -> Battery Saver (off)
- Settings -> Battery -> Adaptive Battery (off)
- Settings -> Battery -> Battery Optimization -> widget app (don’t optimize)
- Settings -> Battery -> Battery Optimization -> Spotify (don’t optimize)
- Settings -> Battery -> Battery Optimization -> Advanced Optimization -> Deep Optimization (off)
- Settings -> Battery -> Battery Optimization -> Advanced Optimization -> Sleep standby optimization (off)
- Settings -> Apps -> Widget app -> Battery -> Background Restriction (app can use battery in background)
- Settings -> Apps -> Spotify -> Battery -> Background Restriction (app can use battery in background)
This helped but not enough to make the widgets or Spotify usable.
Step 2.
I supposed that my specific background tasks that I wanted to keep running were being killed because of the many other apps that were running in the background.
I searched for and found Tomatot DeBloater scripts for the Oneplus 6.
Excellent! Just what I was looking for.
I chose the Tomatot-Debloater-OOS-Light-2.3.zip and installed it.
This helped some more but not enough to make the widgets or Spotify usable.
Step 3.
I realised that there were still some apps running in the background that I didn’t use or want.
So I used Titanium Backup to freeze the following apps;
- Calendar
- Calendar Storage 9
- Contacts (O+)(I replaced with google contacts)
- Dashboard
- Drive
- Face Unlock
- Gboard
- Gmail
- Google
- Google partner setup 9
- Google play music 8
- McLaren AR
- Messaging (O+)(replaced with google messaging)
- OK google enrollment 9
- Oneplus system 1
- Youtube
Perfect! These apps were no longer competing for phone resources with the apps that I wanted to run.
This helped some more but not enough to make the widgets or Spotify usable.
This did make the phone feel faster and smoother.
The phone is much more responsive and fluid to my input.
This made me realize that the apps were being closed not due to a lack of phone resources, but a background task manager being aggressive.
Presumably for battery saving purposes.
I changed my focus to adjusting that background task manager.
Step 4.
Enable the recent screen ‘LOCK’ on the widget app and Spotify.
This didn’t do anything for me.
Everything that I’ve read on it says that it just stops the task from being killed when you click on kill all tasks.
The lock doesn’t lock the task from being killed by the background task manager.
Step 5.
Further google searching led me to believe that the OEM kernel was limiting background tasks.
I choose ElementalX-OP-3.09 and the EX Kernel Manager.
I had to read a lot of google university material to make any sense of the settings in here.
I’m not sure that I fully understand even now.
Eventually, I ended up with the following settings;
Memory
- Adaptive Low Memory Killer (disabled)
- dirty ratio (20)
- dirty background ratio (5)
- min free kbytes (12398)
- vfs cache pressure (100)
Memory -> Low Memory Killer
- apply on boot
- Foreground app (72mb)
- Visible apps (90mb)
- Secondary server (108mb)
- Hidden apps (200mb)
- Content Providers (587mb)
- Empty apps (783mb)
This helped a lot.
This almost made the phone usable to the state that I wanted.
But the widget and Spotify would still stop running overnight and by morning the apps would have to be reopened to get them to run again.
At least the apps would run most of the day without being killed.
Still not the behaviour that I expected from a phone with 10GB of ram.
Ram usage was still not going much over 5.5Gb even if I opened up many apps at once.
Can I ever get ram usage up to the 10Gb that I have?
Step 6.
The last thing that I tried yesterday afternoon was to increase the background task limit in the build.prop.
ro.vendor.qti.sys.fw.bservice_limit=5 (changed it to 60)
ro.vendor.qti.sys.fw.bservice_age=5000 (changed it to 10000)
Yes, I know that I am on PIE and there isn’t supposed to be any effect.
No, I don’t know yet if this had any effect.
I am hopeful.
The widget app didn’t close last night, but Spotify did.
I am getting closer!
This is the best that I could do on my own without asking for help.
So here I am posting my question and asking for help.
How do I get the apps that I want to run to not be killed by the background task manager?
OR
How do I get the phone to use the 10GB of ram?
I feel that I am missing something.
With any luck, one of you smarter persons will be able to point it out to me.
As an aside from all of these changes the phone feels very smooth and fluid.
Except for apps closing that I don’t want to, this phone is a great experience and a pleasure to use.
Apps that I want to run are staying open much longer then before I started.
It’s now just an overnight issue.
And getting the phone to use over 6Gb of ram.
I would suggest that I am 90% happy with it now.
KERNAL: ElementalX-OP6-3.10
ROM: STOCK OOS 9.0.11
PHONE MODEL: 6013 O+6T McLaren

Tomorrow I may try making this change to the build.prop file;
ro.vendor.qti.sys.fw.bservice_enable=true to false
Don't know if it will help or not.

Wow dude, interesting read, i will sign up for notifications from this thread hoping you get your answer because i have the exact same problem but with my work app, throwing it all out of whack and making me a target to big fines (in the $1,000's) and potentially reducing my marketability!
The attached screenies are from before i realized that the app getting killed in the background is what causes the problem (I've left it in the foreground HOURS a few times and it works perfectly!)

UPDATE:
Good news!
I seem to have solved my issue.
Time will tell for sure though.
But this morning and all day today, Spotify and the widget app have been running without closing.
AND I have seen memory usage up to 6.8GB used.
Here are the further steps that I took;
- ro.vendor.qti.sys.fw.bservice_enable=true (changed it to false)
I didn't really notice much of a change.
But then I noticed that perhaps the limit of 60 tasks was not high enough.
I seem to have that many apps open and limiting to just 60 may be an issue.
- ro.vendor.qti.sys.fw.bservice_limit=60 (changed it to 120)
THIS!
This seemed to have worked for me.
All apps seem to be open and be staying open.
Today I got a message/warning from android telling me that the widget app is consuming the battery in excess but I ignored the warning and android did not close the app or stop the widget from running.
I will keep an eye on the phone for the next few days to confirm that this actually solved my issues.
My next step will be to see what effect if any this has had on my battery usage.
I am curious to see if it's all that bad...

Nice find, I checked my build.prop and found this. No wonder my apps are killed
Code:
#ifdef VENDOR_EDIT
#[email protected] modify for app memory
ro.vendor.qti.sys.fw.bservice_enable=true
ro.vendor.qti.sys.fw.bservice_limit=5
ro.vendor.qti.sys.fw.bservice_age=5000
#endif/*VENDOR_EDIT*/
EDIT: I see a lot of custom ROM's have "ro.vendor.qti.sys.fw.bg_apps_limit=60" to the build prop, I wonder if that going to make a difference

UPDATE:
I am a silly goose.
I broke a cardinal rule while troubleshooting.
I may have had a few too many wobbly pops and made two changes at a time, thus when change was affected, I was unable to determine properly which change caused the affect.
The rule is, "only make one change at a time when testing".
Yes, all of my apps stay open all the time.
I am getting the behaviour that I was looking for.
However it wasn't necessarily changing the build.prop bgservice_limit from 60 to 120 that did it.
Let me back up a bit.
Earlier I had suggested that locking an app to the recent screen didn't do anything for me, and that in my reading it only locks the app from being killed by you when you try to close it manually.
However in reading up on the oneplus framework-res.apk I found a reference to an oneplus whitelist of apps that will never be killed, and a reference to the recent screen app lock that suggests that oneplus will add a locked app to the whitelist and not kill it.
In the course of a single day, I had inadvertently edited the build.prop and locked the widget app to the recent screen thus breaking the one change at a time rule.
So the next morning and the following days when all apps were staying open I attributed it to changing the build.prop not realizing that it could also have been the app lock.
Last night I realized my mistake.
I unlocked the widget app from the recent screen and went to bed.
When I woke up this morning the widget app was not running for the first time in days.
Also the notifications that I was receiving about the widget app consuming excessive battery have stopped.
It would appear that I was wrong in my earlier observations regarding the app lock mechanism.
It appears to be very useful for keeping apps running all the time.
Did changing the build.prop have any affect on keeping apps open?
Maybe?
I have noticed that my battery life has gone for a complete ****.
I can barely get 24 hours out of the phone.
Worse is that it doesn't matter if the screen is on or not, battery usage remains the same.
i.e. with the screen off and the phone put down, battery life appears to be used at the same rate as when the phone is in use.
I had expected the battery life to be not as good, but I didn't expect it to go to for a **** that badly.
There must be a balance between aggressive app management and acceptable battery life.
The phone didn't display this behaviour until I changed ro.vendor.qti.sys.fw.bservice_enable=true to false.
I think that today I will change ro.vendor.qti.sys.fw.bservice_enable= back to true and observe the battery tomorrow.

Nice find, I checked my build.prop and found this. No wonder my apps are killed
Code:
#ifdef VENDOR_EDIT
#[email protected] modify for app memory
ro.vendor.qti.sys.fw.bservice_enable=true
ro.vendor.qti.sys.fw.bservice_limit=5
ro.vendor.qti.sys.fw.bservice_age=5000
#endif/*VENDOR_EDIT*/
EDIT: I see a lot of custom ROM's have "ro.vendor.qti.sys.fw.bg_apps_limit=60" to the build prop, I wonder if that going to make a difference

I think that ro.vendor.qti.sys.fw.bservice_limit= and ro.vendor.qti.sys.fw.bg_apps_limit= are essentially the same thing, except for android versions.
ro.vendor.qti.sys.fw.bg_apps_limit= is for Android 7: Nougat and below.
ro.vendor.qti.sys.fw.bservice_limit= is for Android 8: Oreo and above.
Someone more knowledgeable than me should chime in here though.

Do you think any of this could have to do with the way the phone keeps disabling push in Gmail? (Every other day I need to set my O365 exchange in Gmail back to push because it automatically changes to the default of checking every 30 mins.)

Any conclusion?

Did you guys manage to solve this issue please by editing the build prop?

Latest smurf kernel rc14b seems to have solved the RAM management issue. I haven't had any apps closing in background since using it.

thank you for the thread!

What did you find in the end?
How did you set this ?
ro.vendor.qti.sys.fw.bservice_enable=true
ro.vendor.qti.sys.fw.bservice_limit=5
ro.vendor.qti.sys.fw.bservice_age=5000

So what's the verdict on the buildprop edits? Do they make a difference?
I notice that sometimes my on-going weather notification doesn't update, or gets killed off. I also have an app that controls rotation per app, and that also seems to stop doing it's thing after a while.

Just want to share. If you are rooted with Magisk, try appsystemizer module. System apps don't get killed by oneplus as aggressively. Tried it with accubattery and it works.

I am so glad I stumble across this, I just want to say, changing
ro.vendor.qti.sys.fw.bservice_limit=5 to 120
ro.vendor.qti.sys.fw.bservice_age=5000 to 10000
Keep apps in ram for much longer then original! For me the battery life is unaffected, might even be better.

Also want to solve this issue.
On which OOS Version you are? (i am on 10.3.1)
Does this really work in newer OOS Versions?
I have read elsewhere that those settings dont work on newer versions, sadly, cant find the thread/source.
thx

I'm actually Oneplus 6, OOS 9.0.9.
I also read that it doesn't work on Android 10 because magisk doesn't mount /system in Android 10, but there is a magisk module workaround that you can use. And hopefully magisk will update in the near future to fix that. Just google "Android 10 can't edit build.prop" and you'll find heaps of info.

This is what I have in my build.prop file and it seems to help. I have Oreo it works great on my phone I don't know about later versions of Oreo.
ro.vendor.qti.sys.fw.bservice_enable=true
ro.vendor.qti.sys.fw.bservice_age=5000
ro.vendor.qti.sys.fw.bservice_limit=5
ro.sys.fw.bg_apps_limit=64
