Help! Why am i facing performance issues with custom roms

Hey guys. I usually wouldnt have made a thread like this, but honestly, i am getting tired trying rom after rom to find the one that works. I am the sort of guy who switches phones pretty often because i like what Devs at XDA are able to do to customize them. So i have recently started using higher end phones, and coming from mid-rangers i expected awesome performance and lag free experience. My last device was a one plus 2. After switching to mi5(which has a better processor), i have been experiencing lag spikes with rom. None of them work perfectly smooth, I would go to the depth of saying that my old Nexus 5 provides much smoother experience compared to this. Surprisingly, this is not the case with miui. The stock Miui rom aswell as my current rom(cpMIUI) are both super smooth(as is expected out of a sd820). I am stock android guy though, also google camera port doesnt work on miui. I just wanted to confirm if it was just my unit or is everyone facing similar issues. Buying a sd820, i dont expect something as simple as pulling down the notification bar to be laggy. Also. this issue is more prominent with Lineage OS and Lineage OS based roms. I found AOSP rooms to be generally smoother, but still, laggy enough to notice. This really wasnt the case with OP2, and i honestly wouldnt have switched if it wasnt for the amazing camera of Mi5(only with GcamMod ). Any help would be much appreciated. PS: I have tried custom kernels, even those which overclock this sd820 to normal frequencies. But no luck . I really dont have the budget to switch phones rn, and i would like to stick to mi5. Hope someone can help.

Mi devices works better with MIUI... That's just the way it is. Custom rom experience on Mi can't compare with the likes of Oneplus, Nexus, or maybe Pixel...

u can install Gcam in miui just use magisk to root and add camera fix module
Gcam will work in miui9
am using los15.1 and most of the apps freezed now its smooth and giving good battery life

All lags, freezes and scroll stutters caused by kernel. All oreo kernels based on HMP scheduling with perf daemon. And don't know why, but it cant provide smooth FPS while ui drawing (maybe some bug with frequency drops). So, 90% roms based on Oreo will lag while drawing UI all time (you can check it in dev settings > Profile GPU Rendering). Some roms trying to avoid this bug, like LOS, AEXMod with some tweaks in governor. This 2 roms much smoother than other. Or you can change default governor from Interactive to Conservative (root required). It brings massive boost on ui drawing smoothness. Or try something based on EAS kernels (Purefusion, JDC AOSP). But these roms based on 8.0 Oreo.

Thanks for a constructive reply. I am not using LOS because of the fingerprint delay bug, also i found LOS to be the laggiest of them all. But i recently installed Cosmic os 8.1, and this one seems to be rendering fine. It is using the priima kernel i suppose, with interactive governors and cfq for io scheduling. Also, i just checked, it has oc'ed the sd820 to normal frequencies (2.15 and .16)
Also, i have tried Floppy kernel, based on all 3, Google, linaro and ubertc. Also, i tried switching the governor to zen(the one i am aware of thats made to make your ui smoother). This issue is not only persistent with oreo roms, but also the nougat roms. But i have been happy and impressed by cosmic, but i will keep on switching roms and hopefully would be able to provide some feedback to the XDA community.

Absolutely yes! People were blaming me also for using antutu, because I had this doubt, then discovered that the kernel uses a strange sort of cpu scheduler which causes a performance drop of 20/25%, (still can't fix switching performance profile) results were different switching to a custom kernel. I think that people when create new roms they just steal LOS kernel, so that's why this issue occurs in more than one rom.
Anyway I also prefer the stock android camera, and I like to use the "classic" way instead of magisk thing (never liked that), just download GCam, then remove in the framework folder the camera_experimental.jar (or something called like that) and you should be fine, there are some little bugs too but is is usable.

So which kernel are you using rn? Cosmic OS comes with the priima kernel, it is the best experience i have had by far. Glad to know i am not the only one suffering stutters, but also kinda disappointed to see this happen.

Yea, me too, and there were people who treated me like crazy lmao, imo is a kernel scheduler issue, btw Idk why that happens , anyway there are plenty of custom kernels, in particular I used Floppy which fixes the problem.(Still need to tweak some kernel governor settings)

Aye i tried floppy. Didnt quite work for me. Regardless, priima is working fine. I am thinking of switching to other roms. Will try the floppy again, thanks for the advice.

When i said it needs some tweaks, that is because it works in a strange way, the performance profile in the "Battery" section of LOS needs to be set to something higher, that controls the CPU, meanwhile there I also used an app called "Spectrum" that lets you control the GPU performance profile (Even though it should be control CPU), you need to set all of those to "Balanced"

Hello, I have the same problem. My MI 5 only works on miui. Any other newer rom with android Oreo brings me problems, slow looks like snapdragon 4xx. Game performance gets horrible. But they are only in the most recent roms, because in the stable JDC Team 7.1.2 rom it behaves absurdly fluid and fast, in Lineage 14.1 as well. I do not know what causes this but I can not use any more Oreo roms. I prefer Pure Android but can not use the new roms at the moment, I should settle for the nougat or miui roms. Well, I'm not saying that the new roms are bad, the work of the developers is wonderful, congratulations to everyone, but something in the new roms does not behave well.

Try the cosmic os. It seems to be working amazingly well. Also Los never worked for me, full of stutters and the ofc the fingerprint delay on lockscreen issue. Also yeah, jdc aosp should work, in my experiments, all AOSP based roms are working fine, there is some issue with Los kernel, and hence with all roms based off of it.

Best pie rom with no bugs?

With so many pie roms , i dont know which one is good, i tried some but they all had bugs , do anyone know of any pie rom which i can use as a daily driver ?

It's little to early for bugless Android pie ROM, respected developers working to make it stable.
Currently i am using Arrow OS and it's working good, battery backup is also good.
I was using Havoc OS but latest Pie update gave tremendous standby time heat and battery drain rather than that Havoc OS is best ROM with many features. I saw someone saying using custom kernel ROM performance is good. I haven't tried it but if that works then it's pretty good ROM as Android Pie based daily driver.

Use arrow os it has good performance and battery life and it can be used as daily driver. I am using it for more than a week, but Volte doesn't work?

Stable ROM for santoni
Official Reveneg OS is most stable one. I find it better than Havoc OS ( serious heating and battery draining issue) and Arrow OS ( Heating issue ). Check Tech Office YouTube Channel for it's download link and Review.
Be healthy always.

Here's RevengeOS https://sourceforge.net/projects/revengeos/files/santoni/
Everything works, but the default interactive governer doesn't sleep and battery drains very fast. There doesn't seem to be system update in settings either.

Gapps are all there yes, but I've updated my post after using this rom for a day. Basically battery drains fast. IDK why the guy on YouTube said battery life is good on this rom, it's not.

For me, I used Arrow and Havoc. I find it better than those two. I backuped this rom and I can switch to other better Rom If I found. I'm keeping eye on this Rom's next update Ver. too. I was charging my device when I read your Reply. At that time my battery was at 61%. I removed the charger and then went to search for more Posts and Rom's And After that watched some youtube videos about custom boot Logo for Redmi 4(my device) And after almost 25-30 mins I checked my Battery Level again. It was at 59%. I don't know if it's too abnormal or not. I find it Ok (at least for an early build Pie rom for Santoni).
Do you have any better Rom to suggest? I would love to try them.?

Use arrow os I've tried plenty of roms and find it's pretty stable and gives good battery backup.

and although it has a couple minor bugs, like "there error with your device" notification on every boot, it's pretty stable and usable. No major bugs

Android P lag/stutter?!?

Hello community,i had my nexus 6 for 3 years now,been through much Rom/kernel combos,and i never had this kind of lag that i have with all pie roms.Thing is i dont have much apps,maybe two non google apps and probably stock gapps package,so no bloat.With this kind of apps i never get a single hint of lag at lets say purenexus 7.1.2 and franco.Not a single stutter.And ui looks kinda same because i have pixel launchers.Dont get me wrong i know this device is old now,but if it can run 7.1.2 without lag i didnt expect it to lag this much in all pie roms,and i tryed them all,did all i could,even franco cant help eliminate lag,and i dont have encryption.And lag is serious,it happens when scrolling,i know nexus 6 is not oneplus 6t kind of device,and i know games do lag more now,but lagging in ui is just weird,my redmi 5 dont lag at all on android p custom rom,and redmi 5 is just lame compared to nexus.So my question is,do anyone else get lag?My friend also gets lag only on pie roms on his nexus 6.Is there something they did with pie to older devices,i really wish to find answer.I tryed lineage 16 and its really good,it gives new look to nexus,and thank developers from depth of my heart,but it would be soo good to eliminate this weird lag,just because i know this device is way more capable of running pie than most device that have it now.Weird thing is its sometimes very smooth and next moment it lags like hell,it seems like its running at 15 fps.
If you can help me any sort of way id be very grateful.Viva la nexus 6,my friends,lovers of shamu,best phone ever.:fingers-crossed:

I dont experience lag on Pie personally, buttery smooth for me. If you havent tried it yet, try rebooting your phone in safe mode and once its fully booted, do a boot into normal mode. I have had times with severe lag and this cleared it all up.

May i ask what rom/kernel combo do you run?My nexus lags and gets hot on all pie roms,and that dont happen at nougat or oreo roms.I tend to run phone as lean as podsible,so i dont have apps that i dont need,and i think that shouldnt be a problem,and i see when using phone that sometimes its smooth,and next second it lags when i scroll.I restored to purenexus 7.1.2 and i doesnt have a single hickup on it,battery lasts long,and it doesnt overheat at all.Problem is i like pie more,than nougat or oreo.

I was running Nitrogen for a couple months till 2 days ago and I was using its stock kernel most of that time. I am now running Revolution Remix Pie with Popcorn kernel. No lag at all. I use Apex Launcher and Brave Browser. Mostly use phone for calls , texts , and youtube. No issues at all. I dont use any backups that came from Nougat or Oreo. Try what I suggested.

You were right,it was even worse,lagging even on 100% battery,with no additional apps installed other than some basic gapps,this is becoming frustrating for me,maybe its only my device,but it makes me sad that it cant work well with pie.Can it be because its 32bit cpu?I really cant beleive that my nexus 5 on pie works like 200% better,doesnt have a hint of lag.Its kinda unbeleivable.I did all i could time to go back to my old purenexus and franco,at least it was solid and not laggy.Maybe this phone just isnt strong enough .Thank you all,if anyone has any more ideas ill gladly listen to them.And thank you elektroshmock for caring about our device,keep the good work :fingers-crossed:

For how long have you tried each pie rom? I believe that the rom runs some background optimization after install, so I wouldn't judge speed until a few days have passed.
Does it run faster when connected to power?

The lags have to be from your personal phone or setup. Like I said, I dont experience lag because if I did and I thought the Nexus 6 in general was uncapable of running PIE smoothly, I would have replaced it by now. Did you reboot your phone in safe mode and then back in normal mode while using a PIE rom?

Well i cant allow myself to use laggy phone for more than few hours,lets say all nougat roms i tryed ever smoothed out in few minutes,and never had lag or stutter or overheating,it seems to be the last os that worked without any problem on my phone,as oreo did work ok,but not like nougat,nor did i ever get battery life like i get on nougat.But id say oreo was acceptable.On all pie roms except maybe carbon that i used for 3 months,id get all sort of problems,cracking top speaker on 40% battery,shuting off at 35%(battery is not bad as this never happens except on pie),and as i saw pie roms with different kernels,do have strange cpu behavior,shutting of cores,settings not sticking when applied in kernel manager apps,i disabled mpdecision,still same,i lock cpu on max,set governor to performance,gpu governor also performance,i did everything i knew(not to brag but i think i know a lot about this device)but i think my unit which was first batch even tho i bought it later as new,it has some weird electricity,power delivery issuses,it seems like it needs more power(voltage?)then the battery can provide.And this speaker electricity crackle annoys me.When it makes that sound i think its gonna burn or something,because that sort of sound is same like when you hear electrical sparkles and it starts to lag heavily,never ever i got this strange sound on any phone i had.And when using on my turbo charger it gets so hot i think i would be able to fry egg on it without any problem.
 @Derrick
I did all you told me,started in safe mode on pie nitrogen,but even in safe mode it lagged heavily,i dont really know what happens with my shamu and on pie i think i got 58 celsius on battery and 87 celsius on cpu i thought thing is gonna burn to ashes.Same second i revert to pure nexus and franco it becames ultra smooth,and ultra cold now i have 23 celsius on battery,and 35 on cpu.Just very weird,because performance on nougat tells me my device is more then acceptable of running everything smoothly,but for some reason pie roms breaks it into half.I think i heard something about opengl(skia)render on pie making it lag.If someone knows how to force old opengl to use it on pie tell me,i think ill try that if i get any information on how to do it.

Well i cant allow myself to use laggy phone for more than few hours,lets say all nougat roms i tryed ever smoothed out in few minutes,and never had lag or stutter or overheating,it seems to be the last os that worked without any problem on my phone,as oreo did work ok,but not like nougat,nor did i ever get battery life like i get on nougat.But id say oreo was acceptable.On all pie roms except maybe carbon that i used for 3 months,id get all sort of problems,cracking top speaker on 40% battery,shuting off at 35%(battery is not bad as this never happens except on pie),and as i saw pie roms with different kernels,do have strange cpu behavior,shutting of cores,settings not sticking when applied in kernel manager apps,i disabled mpdecision,still same,i lock cpu on max,set governor to performance,gpu governor also performance,i did everything i knew(not to brag but i think i know a lot about this device)but i think my unit which was first batch even tho i bought it later as new,it has some weird electricity,power delivery issuses,it seems like it needs more power(voltage?)then the battery can provide.And this speaker electricity crackle annoys me.When it makes that sound i think its gonna burn or something,because that sort of sound is same like when you hear electrical sparkles and it starts to lag heavily,never ever i got this strange sound on any phone i had.And when using on my turbo charger it gets so hot i think i would be able to fry egg on it without any problem.
@Derrick
I did all you told me,started in safe mode on pie nitrogen,but even in safe mode it lagged heavily,i dont really know what happens with my shamu and on pie i think i got 58 celsius on battery and 87 celsius on cpu i thought thing is gonna burn to ashes.Same second i revert to pure nexus and franco it becames ultra smooth,and ultra cold now i have 23 celsius on battery,and 35 on cpu.Just very weird,because performance on nougat tells me my device is more then acceptable of running everything smoothly,but for some reason pie roms breaks it into half.I think i heard something about opengl(skia)render on pie making it lag.If someone knows how to force old opengl to use it on pie tell me,i think ill try that if i get any information on how to do it.
Thank you for trying to help me guys .

It probably would be good time if it was lagging on nougat,but i can keep it for some more time,i think i wont even sold it like i did with other phones i had(it will stay with me just like my nexus 5),it really is my favourite phone,even tho its not perfect by any means.I thought about possible new phone and i hate new trends of bezeless screens,and especially i hate 18+:9 screen ratios,it makes phone look like tv remote,and there isnt much phones that fall into these categories.And of all the good phones i think the one id get is probably pixel/pixel xl and pixel 2 but every one of them is plagued by its own set of hardware problems,and that makes me unsure about possible purchase.

I wonder what makes Carbon so special, because it's using LineageOS's Kernel and devicetree for shamu.
I don't know which Pie ROM you're using now, but at least LineageOS for shamu doesn't want you to fiddle with kernel settings.
If you choose to do so there is a very high chance your cpu freqs get stuck at very high levels, which causes your devices temperature to rise, which causes thermal deamon to kick in and limit your maximum freqs.
In general no matter how much you think you know about your device before you fiddle with any setting you should ask yourself "why didn't the device maintainer set it in the first place"

Truth be told,i surely know less than you do about this device,and i said it didnt cause me problems with mostly battery.At least thats how i remember it,it gave me less problems for some reason than all other pie roms.But after some time it started doing the same thing like all other roms and that made it unusable so i got back to nougat which im using today even tho i like pie more,design wise.Nougat has much better performance and much better battery life while also not overheating.Id really love that pie works like nougat,but if it isnt its not end of world for me,ill still happilly use shamu on nougat.Maybe lags are only on my device,but i cant find any reason that it happens,i tryed all i potentially know,and its not shame to accept that i dont know everything,thats why i asked people here that probably know way more than i do.I with my minimal knowledge suspect that shamus CPU is culprit here,being 32bit,and maybe new renderer in pie which cause system lag for me and some other guys.My friend lags on stock pie,stock kernel on his pixel 2 xl,thats just not acceptable.Google software+google phone(hardware) and it causes lag on snapdragon 835,its not weird that it lags on 6 year old,ancient 805 which is hardly any stronger that nexus 5 snap 800,but nexus 5 have 1080p and shamu 2k screen,and that probably causes problems for nex6.Being first batch of 2k screen devices i think system on chip that they put in it wasnt ready for what it needed to do.Just my thoughts.

Heat fix or anything for redmi 4x?

I live in hot city in india. I have been experiencing alot of heat lately in back where CPU is located. It's always 40c battery as well as CPU both stays on 40c. Please let me know if there is some tweak to reduce heat. I dont do much gaming. I use it for chatting and watching videos mostly surfing YT or surfing internet. it makes me paranoid whenever it gets heat up i m always forced to keep it aside till it gets cool down. I am requesting to any developers here to make a tweak or make a kernel for users like me as it will be soo helpful for many people who dont like to feel heat while surfing on net. Please do look into it.

Also do tell me if there is a good rom. I dont care about latest android version or latest security patch all i want is i should be able to chat or surf without feeling that heat in my hand because it just ruins everything for me.

I am using official LOS 15.1 and am satisfied with it from a heat perspective.
The only time I maybe encounter unusual heating is when the NSA is hacking my phone to spy on me. *joke* What I then usually do is just to shut down my phone and leave it off for a couple of minutes.
You should look to update your firmware to the latest available Global version.
It is otherwise a good idea to reinstall your phone. You never know if you picked up some malware through dodgy apps that is causing the problem or if some apps are just rubbish.

I Use Xiaomi EU
No issues of heating except if you Play games.

Stable or developer version?

rom PE official latest update

I installed "crDroidAndroid-9.0-20190613-santoni-v5.5" yesterday.
In my country, the temperature is not so high during this time.

heat is normal when you use it

Use kernel adiutor to tweak settings. Or use a custom thermal mod

Hey. Peeps! Thanks for kind response. I read all your suggestions! I m using Lineage OS latest official build. I dont do gaming its battery efficient also it has quick charge support, on ampere app readings says 1800ma. I m thinking of using MIUI now, i have used EU rom and trust me Lineage OS is better in terms of battery backup. Crdroid, umm, thanks @mcjohn, i will try this.

Read my last post ?
I do not recommend CrDroid.
It's an unstable ROM.
Wait for an update.
Yesterday I installed "COSP".
I do not know how behave !?

I actually tried it.. Not bad , not good. Lineage OS is the best currently. I m thinking of trying out pixel experience rom, i have seen people claiming it has good battery backup.

Btw, dont ever use miui official rom. It sucks the battery so quickly. -_- I m currently on stable miui global rom and trust me it has worst battery backup.

I installed several ROMs.
Everywhere, I posted my opinion on settings or battery!
"Somebody" criticized me because I was too subjective !
Try some software, then stop at the one you like.

I used the MIUI ROM when I bought the phone until I unlocked the boot charger. . . Then I install another ROM every month.
Or, maybe 2-3 ROMs per week !
Look at my pictures and see how the battery is consumed, how the phone heats up, or the settings that are missing from the menu.

Best miui 13 port for redmi k20 pro ?

Im still running miui 10 and beside sensor issues in the worst moments and batteryperformance decreased (8-10h sot), im pretty happy.
The release of miui 14 looks pretty interesting, same like miui 13. Unluckily xiaomi will never bring any of those and therefore might xiaomi.eu never aswell.
Meanwhile is there any miui13 port which is super stable and perfectly working (i heart of ghost, miui tn, aphixrog). Im looking for something to flash, forget and never regret (for the next full year).
How is the battery performance ?
I would prefer stock vendor & kernal, no custom "magic" from few days experience dev .
Or should i forget about the "upgrade", stay on miui10 and investigate the drain issues ?

I've tried Abhix.
Thread '[Q] Has anyone tried miui custom roms MIUI SR or AbhiX ROG Edition (both are ports of MIUI 13 on Android 12)' https://forum.xda-developers.com/t/...h-are-ports-of-miui-13-on-android-12.4530039/
How is it possible that you have 8-10h SOT in 2+-year old phone? 5h SOT is pretty good, 6 is very good.

Depends on the usage, but everything on my phone is adjusted to consume as less as possible (but i havent done wild stuff like lower clockspeed, kernal, voltage... only debloat, disabled everything which could be battery intensive in settings, using leandroid + greenify), meanwhile i range between 7-9 hours i guess, when i fresh installed it i ranged between 8-11 hours.
My battery should still have efficiency around 85-90%, im trying to hold battery between 15-85%.
To answer your question. I personally think everything after miui 10 is bad.
I may gonna try MiuiTN, according telegram groups that seem to be the best miui 13 port.

8-11h SOT? Picrel or didin't happen.
Which version are you going to test (https://miuitn.vercel.app/Rom_MiuiTN/Raphael/) and is there any info how to install (recovery version, filesystem, etc.)? And the most important - how safe is this?

I dont have specific plans so far, because i didnt got enough time, maybe in christmas vacation.
Probably 1.8 and i read once that you need a specific recovery (unluckily cant tell you which).

I checked miuitn 13 A12 but it doesn't have all languages (there is English and a few Asian ones only). Android security updates are from June, while RaphaelOS (also Miui 13 - 22.8.25, A12) are from August 1st. In general, I have the impression that all these roms are very similar. On stock kernel geekbench is 690 and 2675. On Steroid is 700 and 2747. But AbhiX feels more snappy.
Both roms (AbhiX as well) are without encription so you need standard recovery (I have latest official OrangeFox).

If there is a workaround to get native language in apps for me personally its not a big problem if i got english in os.
I havent tested a single miui 13 port so far, so i cant bring useful informations to this conversation unluckily.
According telegram groups MiuiTN seem to be the most stable, balanced rom and others are "kanged", but well yeah people talk on telegram...
I unluckily wont have time to test all of them myself so i might follow your experience ;D and maybe some other guys come along this thread and share their experience aswell.
Worst case i stay another year on miui 10 and get Rog Phone 6 after... Im just hell of annoyed my sensors do not work how they should on miui10 sometimes.

About Rog Phone 6 - it bends -
About native language - you can try https://github.com/BlueCat300/XposedAppSettings/releases

Dont go for RaphaelOs.
Better go for Miui12 or MiuiTn.
Im on VoltageOs 2.1 which is awesome, i heard also good stuff from Los20.

BTW I'm using Evolution X with stock settings at 72Hz with no battery saving tweaks. I bought the phone more than 3 years ago and use it daily. Afraid to replace this beast because I'm so used to this good SOT.

I easily reach 10 hours sot + on voltageOS. I shared some screenshots of 11-12 hours sot on my 3 year old battery in telegram group with light-medium usage. My idle is dope aswell, most of the time lower then 1% (ext4, voltage2.1, bitgapps, magisk delta).
I heard similar good from LOS20, Android 13 seem to be awesome in terms of background managment (im using 100+ apps).

I've heard only good things about VoltageOS. Are there any issues with it, stuff that does not work?

I have used EvoX 2 years back for a while, cant compare it unfortunatly and i wont flash another rom until i buy a new phone probably.
Well unluckily there are a few issues on Vos2.1:
- Udfps unlock sometimes does not work. (there seem to be the same issue on Los20 and according Los20 dev it seem to be a issue with android system)
- nightmode, reading mode, extra dim does not work together with dc dimming after unlock. (according Voltageos dev this is a common issue on most aosp roms)
- from time to time i notice scrolling laggs and rarely in games aswell. (could be related to kernel, but not sure)
- expandable screenshot ?long screenshot? slightly buggy ? (on miui it have been working better)
- on twitter i have noticed some issues like i couldnt go back to overview after reenter app, on discord after editing i have noticed scrolling does not work anymore. (but those issues can be caused by the app / restricted battery setting / android system idk)
Thats all i have noticed so far, more or less (if i have not missed anything). Anyway im very happy and think its a really great rom. The only thing which is bothering me the most is udfps unlock inconsistency and for night mode + dc dimming i am using twilight. (those things have been working better on miui, not gonna lie. )

Thanks for the thorough review, friend!
I might just give it a go one day. I must admit that MiuiTN also looks tempting since I like the classic Miui style, but I can't find much reliable information on that rom.

I have not been using miuitn for a long time, so i unluckily cant tell you more about that. Miui13 ports for sure arent as stable as official releases / xiaomi eu roms.
So it might depends on your personal usage, you might not get around trying it out at your own.
You can also join the telegram group, there you can follow discussions about miuitn releases. People this days most likely use telegram. (which i personally dislike over xda, but what ever.)
