Slowdown

Hey guys,
I got my N10 in the very first batch, bought it on day one, so it's been around six months now. Lately, for the past month or so, I've been starting to experience some slowdowns, and it's starting to be hurting my experience a lot. My Chrome app, for instance, takes a long time to register, and if I press on the "Home" button to go back to my launcher, the button is highlighted in white for 5 seconds before effectively going back on the home menu. Does anyone know what can be done about that? I'm considering a factory reset, but I'd rather keep my saved data and files for my apps and not go through backing up my dozens of apps. Thanks

First, don't use Chrome, it still sucks when compared to the AOSP browser, download the app Greenify from the store and use SD maid to delete all the unneeded stuff you have on your Nexus.:good:

You could try doing a factory reset and perhaps try installing a new ROM or kernel whilst you are at it as there can be speed gains with some of the alternatives to stock. It doesn't really take long to back up your apps with the right program. Have you looked at titanium backup?

I assume you have done a shutdown and restart? I was getting slow responses and that cured it for me.

Even chrome beta is a large improvement over chrome. Most of the ROMs have large speed ups over stock so I would suggest that or at least a new kernel if you don't want to back everything up.

I'm going to do that, thanks a lot! I used Dolphin for a little while but never really liked it, so I came back to Chrome, I'll look at some other browsers though. I'll look at new ROMs and Kernels as well, I've been wanting to try paranoid android for a while.
Thanks people!

Sv: Slowdown
When I only have about 2gb or even 3 I think the sdcard gets awfully slow for me. I have 32gb version. Drop from 20mb write speed to below 5. And a lot of things are really slow. Cleaning up to get some more space solves it for me. Has happened twice so far. Not sure I my nexus is bad or if this is normal but a hint is to check your sdcard speed.

similar issues
I've experienced similar issues but i can say much of my slowness started immediately after the 4.2.2 update. Prior to the update, my N10 was performed flawlessly. I don't use chrome and will try out Greenify and SD Maid and see if that helps.

Quick update: I realized today that I thought my N10 was rooted, while it actually wasn't. I used the N10 rooting toolkit a month or so ago, and I thought it worked, but didn't actually try it. However, Greenify kept telling me to grant it SU and I ended up noticing I couldn't actually explore the root in ES File Manager, so I did a root and flashed the KManta kernel.
So far, it's EXTREMELY smooth, just like when I got it. However, having only 500mb of apps on it helps, hehehe.
I also received my Patriot Node, on which I'll put all my media files from now on. I am going to experiment to see which ones work and which ones don't.
I also deleted all the useless apps I had (which can be many). I am not sure of what I lost exactly, but I'm sure I didn't lose anythinig important, except for my Mass Effect Infiltrator save. Whatever
I almost flashed Paranoid Android, but then I figured I like the stock rom and didn't need a different one.
As for KManta, does the fast charger actually work? What does it do? The thread here on XDA doesn't say much, is there any way to have more info on its features?

It supposedly makes charging faster when connected to a computer usb port... I've never tried as I don't have a PC
I can tell you it does nothing when charging from the power adapter

Fast charge AFAIK is not implemented for our kernel yet

oh ok, great, good to know, thanks guys!
Just a noob question.. Assuming I don't change any value, is this kernel still supposed to be faster than the stock one?
Also, I'm guessing undervolting will make it slightly less powerful but eat less battery whereas survolting it will add to performance and kill the battery (and the hardware)?

[Q] Encrypting Nexus 4 - Some Questions

Hi,
I am thinking about encrypting my Nexus 4. I am already using encryption on all my computers but I never tried it on my smartphone, so there are three questions I hope you will answer:
1)
How is battery life affected? Well, fortunately the battery of the Nexus 4 is quite good and I hope encryption won't waste too much.
2)
How is speed affected? My Desktop CPU has AES-NI and there's a SSD, so you don't even recognize system encryption. How is it doing on the Nexus 4? I'm just doing the usual smartphone stuff, means E-Mail, messaging, phoning, checking News &Weather and sometimes playing Doodle Jump. My research on the Internet about encryption performance on Android didn't bring up things I can really rely on so I hope someone here can tell me his experiences.
3)
Which algorithm is used exactly? I know it's dm_crypt and I'm using it on my other computers, too, but on my PC I can choose which algorithm I want and on Android it's given as far as I know.
Regards,
becha

You can't use patter lock to unlock your screen, which is a pian for me right now.

1. Barely noticeable
2. Same as 1
3. Not sure
Sent from my Nexus 4 using Tapatalk 4 Beta

1) I doesn't notice any real impact on battery life. Used the N4 several months before encrypting it.
2) Booting the phone is slowed down, and not only because you have to enter the key for accessing the encrypted drive. But opening apps and doing backup, etc. isn't slowed down. I guess I wouldn't even notice an encrypted devices and so did no one until now, while using my phone.
I was also doubtful before, because in my experience, on a laptop back in the days (5 years ago), the battery drain and performance impact was just to big. But on the other side, I do a lot more disk based tasks on my laptop, than I do on my phone.
in short, after I lost my last phone, I really wanted to give it a try and I didn't regret it until now.
Hoping to hear good answers to question 3.

@HB_Mosh
Well, that's not too bad for me because I don't use Unlock Patterns.
@Vanhoud @memleak
Thanks for sharing your experiences, I'll give encryption a shot.

can you please tell us your experiences, i was thinking about it, i guess you can CWM, encrypt then restore backup if you want to revert without starting all over

Yesterday I encrypted my Nexus 4, it took around an half an hour. Until now (well, one day...) I didn't discover any problems apart from the fact, that my Nexus 4 did a simple restart for the first time when trying to encrypt it. Everything went fine when trying the second time. The phone itself runs fluent, so up to now I didn't see any performance problems.

Now I can't backup my ROM - any suggestions? Perhaps Recovery can mount to an external USB storage or something? What a pain! You can't un-encrypt either, and there's no way to mount encrypted storage in Recovery I wanted to backup before installing privacy protection in case it borked my phone.

Another encryption question...
Don't mean to hijack this thread, but can anyone tell me if OTA updates will still work on a stock, unrooted N4 that's been encrypted?
Can't find a definitive answer - some have had success on other devices and others haven't.

I don't see why turning on stock encryption on a stock unmodified device would make any difference?

I wasn't sure why / if this would make a difference either but as I said, I can't find a definitive answer. Some people say that you need to factory reset in order to remove the encryption before you can apply an OTA update, but others say different.
I'd be interested to know if the OTA would work after simply asking you for your encryption PIN on reboot, or if the encryption would prevent the OTA being applied because of the encrypted storage. Does anyone have any experience of this?

You have to use TWRP Recovery, which is able to mount your encrypted internal storage.

No way.. I thought I'd tried every option I could think of in TWRP but I'll take a closer look.
Sent from my Nexus 4 using Tapatalk 2

If you start TWRP, it should automatically ask for your passphrase to read the encrypted internal storage. Latest version of TWRP works for me, older ones had bugs regarding to encrypted devices.

Downgrading, Upgrading, Disaster, But a beautiful phone. And Some Crazy Questions...

DOWNGRADING TO LOLLIPOP:: --- B151 from B331
I got it all sorted fellas.
Went to the 5X Repository. Downloaded the Stock 1.51 firmware. Placed the "update.app" from it under "dload" on sd card.
Opened up SuperSU on phone and went to settings to remove root and reboot.
After reboot hooked phone to computer and adb flashed the stock 1.51 recovery found in the repository. "same method as flashing twrp, only use 1.51 recovery.img instead"
Reboot phone again and then powered off.
Hold Volume up/down and power to restart and it updates form the 1.51 stock firmware on the SD card WIPING ALL DATA.
Now fingerprint and all factory settings are restored!
Thanks to all, and hope this helps others coming back from Marshmallow or CM13 like i did.

Figured the above was an important surprise for some of you... OP still valid
Hello Everyone! Im new to the whole Honor 5x thing, coming from an m8 now, and before that a nexus 6, and before that a z3 then before that an S4 and before that an HTC Evo 4G LTE... Along with some minors, LG Risio, Moto E, S5...
Im just happy to say that so far I really enjoy this phone! Within the first few days of using it on Lolipop, i was getting 1d 15h type battery life which if youve looked at the phones ive mentioned so far... Really..really..wasnt what I was used to. A Day? For sure, the htc would be at 18% getting back on the charger... and it would die at 10%... with how long id had it. But... A Day was doable.
Ive been looking for a phone for SOOooOOO long now that had good enough battery to last a day at max brightness... Tweaking kernels, and Installing various ROMS (all of them per device)... Crack Flashing, as some would say. It just became a hobby... Ive noticed many weird things about the community, to those reading... let me list them now...
1. People all of the sudden(within the last 2 years?) prefer stock android over anything, regardless of what additional features are being added... Such as battery life improvements, Multitasking improvements, theme improvements, usability improvements... People like stock android... hmmm?
2. People want to be nexus so bad they will theme other UI's to death, just to make it look like stock, generic android... hmm..
3. Battery life, while a common complaint, seems to be indifferent to how frequently people update their phones.. (note: Marshmellow EMUI has a multi core battery bug, listed on XDA under mods..) or what ROM they choose (note the most popular rom being one with significantly worse battery life than stock)
4. Security improvements are completely unnecessary to the community (note the most popular rom being one that hardly supports the fingerprint sensor)
5. No matter how many bugs (even those listed in OP) people will always flock to the latest update of android. And then subtly complain to the developer about the bugs they already know about..
Such a strange mixture of people...to be sure.
However what ive noticed here, is a complete lack of readily available information, so i am hoping some of you might be able to assist me.
TL;DR
So I succeeded in downgrading my phone from MM to LP, as the battery life thing is a legit problem for me, as much as it may not be for other people. However the fingerprint sensor has been disabled, and no longer exists in the settings list... nor is it part of the startup. (confusing to be sure, you would think it would be there, and just FC when clicking on it were there to be a bug, or if the OS didnt detect the sensor or something... it should still be there yeah? If i understand how it works...
Also I cant seem to flash a B151 rom at all, being on B33...3? <- marshmellow... and im assuming at this point that means i wasnt supposed to be able to downgrade... (oops)
So i got TWRP installed (whats up with all the random errors twrp is throwing? Assuming thats normal...?) and am awaiting a BMarshmellow rom to finish... Which leads me to...
Where are the Emui ROMS? Unless its closed... but if this rom maker can do it... ?
and also, is the fix to the battery life on marshmello noticable to those of you who also care about battery life at all?

Marshmallow battery is really bad compared to lollipop.. we had a BIG.little concept that worked great. But Huawei decided to make it a 8 Core CPU even when idle. If someone could make a kernal that activates the 4 BIG cores only when needed it would be approciated! Stock it runs almost always with 8 cores and the highest freq. This phone is really let down by poor software..

Well there is a fix for it in the mods section that fixes battery. Finally got this phone back to functional lol..
Anyway, the fix for the moment anyway looks like it works, just has to be redone every reboot but really isn't that hard. After applying mincores mincpu 0 the big cores only light up when necessary. So far its helping a lot with battery life at least noticeably. Listented to music the whole way to work this morning and was still at 97% when I got there (I have an hour drive) , and that's using Youtube Music over 4g.. Not too shabby.
Yesterday I got to work doing the same thing on marshmallow at about 85-90 so it is doing something, and watching Kernel Auditor shows the big cores turning off when not in use. Worth checking out, applying the settings that are mentioned there don't do much im afraid, as I cant get them to stick through a reboot yet.
Currently writing an init.d script to make that happen every boot.
For now to my knowledge though it is working. Though I think lollipop was for sure better apps on screen off actually worked properly -_-; which im noticing more and more it doesn't anymore. Its more like a Doze control which is annoying because Doze is not near as good as stock lollipop control. I cant seem to revert back to lollipop and keep the fingerprint sensor though, if anyone figures that out please let me know!
TL;DR
I cant seem to revert back to lollipop and keep the fingerprint sensor though, if anyone figures that out please let me know! Id much rather downgrade than continue to fix marshmallow.
Though for those of you wondering, Viper|Atmos//Sony Beats the audio mod works perfectly on this phone

Just finished Init.d for Mincpus to fix the whole Big Little problem Super good stuff. Phone now booting in the big little mode you were talking about. super easy stuff.

Anymore u tried? I posted that script but still EMUI is an heavy OS im waiting for CM to be abit more stable. U can revert back to LP using a local update though dload. I did it aswell when my phone was bricked. Fp is not working because u miss the firmware

I also lost fingerprint when going back to lollipop. I'll let you know if i come up with any fixes for it.

@Demian3112
So Dload for lollipop will revert back from Marshmallow and keep fingerprint reader? Interesting... Does the Dload relock the bootloader? Sorry for the somewhat noobish question, new.
Just looking through sys at the moment to understand the language used for big.little, seems to be a comma separation for them. Wondering if I can set min max this way and keep cores 4-7 at min freq 200000. Also looking for a way to get all big cores to disable when not in use, not just 3 of them which is the current.
Swap set to 0 in marshmellow, seems to speed the phone up a little.
testing Xposed here in a bit to get a few different features, debloated the phone, mostly normal stuff. Playing with other CPU files at the moment in root browser to see what I can do regarding the power draw from the CPU...
set SElinux to permissive to allow for proper audio playback through Viper//Atmos//Sony//Beats...Found Multiwindow, enabling that soon, don't know why it was ever disabled?
Otherwise mostly enjoying the phone at the moment, still above 80% battery with all this that im doing and im half way through my day. the CPU thing really helped with the battery draw.

You should try CyanogenMod 13: excellent battery life, USB OTG and gyro working, much better CPU & RAM management...
FP reader is working, but you must upgrade to MM first (to update trust zone and radio firmwares).

It stays unlocked.. u Miss firmware thats why it doesnt work get stock firmware for your device and it should work not sure how you reverted.. keep in mind u will lose all data and stuff.

Oh of course, I loose data all the time anyway so im used to that flash far too often to be healthy.
I reverted via a twrp backup, used emergency data recovery to factory reset using stock recovery, then it let me boot into lollipop, just missing that all important fingerprint reader//navigation tool. Will most def do that soon, at 60% :/ not sure where the random drain came from. just an hour later and lost 20%? Has to have to do with Screen off app closing. Huawei probably did the lazy thing and just changed over from their own tools to doze I guess that helps while its on your bed at night? And then never again?
As for CM13, im fairly apathetic to the topic... Not to be annoying, or rude, but ive heard the excellent battery life claim a million times about stock android, and while ive noticed its improvements over something like...say, Sense, or Touchwiz... Ive never seen it beat the z3's battery saving tool (before marshmallow), or as of the day I got this phone, Huaweis non-debloated lollipop.
Ive never seen a phone still be at 30-40%, at the end of work, the day after the day I charged. Until this phone. The Z3 would make it a little past lunch if I barely used it on day 2, but this phone played pokemon go for 2 hours the day I charged it, I spent the day listening to streaming music, browsing for various small things, watching a few youtube videos, a little navigation... And it had 40% when I left work the next day lol at 100% auto brightness. Id love to see some screen on vs idle drain comparisons between this phones CM13 and Stock, at that point, ill believe a battery claim.
It played pokemon go at 60fps and the game is a known battery/gpu hog (s7 plays slower than this phone, likely due to lack of gyroscope?)
other than some various laggy UI glitches, the phone was pretty much what id been looking for (I Prefer Miui over stock android, this phone is similar)

What buildnumber and Custom version/Cust do you have? Might be able to link you the right firmware.. twrp backup doesnt backup firmware that explains that you dont have a finger print, is the H from Honor at boot logo Red also?

I got it all sorted fellas.
Went to the 5X Repository. Downloaded the Stock 1.51 firmware. Placed the "update.app" from it under "dload" on sd card.
Opened up SuperSU on phone and went to settings to remove root and reboot.
After reboot hooked phone to computer and adb flashed the stock 1.51 recovery found in the repository. "same method as flashing twrp, only use 1.51 recovery.img instead"
Reboot phone again and then powered off.
Hold Volume up/down and power to restart and it updates form the 1.51 stock firmware on the SD card WIPING ALL DATA.
Now fingerprint and all factory settings are restored!
Thanks to all, and hope this helps others coming back from Marshmallow or CM13 like i did.

Your Reply has been added to the OP for those concerned with Downgrading. Figured it might be nice to stumble upon the directions that, after reading many posts throughout the various roms, many people might actually be looking for. Will likely try this tonight when I get home, battery is much better with the battery fix, but not as good as lolipop

Great.
Hope to help others that were stuck the same way

@igotlostintampa flashed CM13 today.. Im sold on this device i would suggest you to upgrade aswell.. Everything works no bugs so far and its smooth as hell. Battery is insane.. Every core has a task and with normal use it doesnt even scale above 800mhz and the other 4 are offline all the time only when needed they get activated.. Since 1PM i lost only 20% battery (Im on 23 now) while i was installing CM also.. Deffinitaly recommended

Alright so question for you, im interested in that CM13 seems to be using the big little concept we have been speaking about...
((Marshmellow Big.Little Fix does not function properly. It resets without reboot being required, just takes longer to apply than the core modifications under smart power saving, init.d through kernel auditor on smart battery saving mode does not run script on boot, must be manually executed))
Does the CM13 Fingerprint reader allow you to pull down notifications? Will likely check it out, interested... Also, how about a screen off task killer? Is that present... Looking through its forums.

No fingerprint pull down.. No gestures for it yet. No off screen taskkiler but thats fine its stock android you will have enough memory spare.. Got 10 apps open right now no issue and u can instant change to one. CPU is tweaked already with kernal adiutor u can turn off cores manually and tweak it to what ever you like.. Day 2 of using battery is better.. ALOT smoother u can switch from app in a instant no waiting time at all. If u have any questions just ask it. Rom is stable enough for daily use no bugs so far!

Ah see im not worried about memory usage, I never run low on a stock rom in the first place. Stock android has this problem where it allows some apps to sit open eating battery life when the screen is off. Instances of this include facebook, Google maps, general overall "Wakelocks" not present inside of the stock Huawei rom, that prevent the phone from going to sleep even though they aren't doing anything. The off screen task killer is there to close apps hogging battery life in the background that should have turned off when they weren't needed but didnt, after your screen turns off. For the most part this is the cause of the smoothness that you feel inside of a rom. Its going to be smooth because none of the apps are ever turning off, its a balance scale.
Not a big problem, I don't mind fixing that its really easy lol, just curious. As for the gestures that's a little disappointing.. It just seems like I may have to add a bit, but I can try it before I run over to lollistock, ill test it out today. You've convinced me with a claim of good battery though lol, and your previous comments about marshmallow, don't let me down!

GApps on Rooted LG V20

Does anybody know if we are able to flash any other versions of GApps on the rooted LG V20?
My V20 is from AT&T and since day one it has had terrible battery life. Where I was able to use my Note7 or Droid Turbo all day and still have battery left, the V20 eats the battery charge like Sally Struthers in a See's Candy warehouse. I mean, I have to charge this thing at least 2 times a day when I use it to search the web or any battery intensive purposes. I never had this problem on any other phone. I have been trying to find ways to improve my battery. I used Rom Toolbox Pro to disable all kinds of stuff, and it worked great, until my phone started Grand Mal seizing giving me the Google Play Services has to close notifications, which I then had to factory reset just to get my phone working properly again.
I would like to try flashing a minimal version of GApps that pretty much just has the play store and play store services. Are we able to do this on our V20's without having any issues? If you have any input at all I would really appreciate it.

IMHO it must be an app or two you have installed draining your battery like that. On a full charge I can a whole day and a little in to the next. I am a heavy user too. Are you blasting the brightness at 100% all the time? If so auto brightness will help a little. Go in to setting and see what is using that much drain

I was thinking it might be something I installed, as well. But I can't seem to pinpoint any apps that might be causing the battery drain. I keep the screen on auto brightness like you mentioned so it shouldn't be the screen. GSam almost always shows the Android System and Kernel (Android OS) at the top of the list of battery-draining apps. I love the phone, I just cannot figure out what is going on. I mean, I am not doing anything different than I have on my previous phones, and the V20 seems to be working fine. I thought maybe it is something with Nougat. I will gladly post some pics of app usage or data if it might help figure this problem out.

What rom are you on? Are you on stock white theme? I'm running a dark theme, which can help save a little juice. I'm also running as many team blackout apps as I can (many Google apps) to avoid all the whiteness. Just throwing out some ideas.

Interesting! I have never heard of Team Blackout Apps, they look pretty nice! Yes, I am on the stock ROM just the way it comes. I haven't changed anything at all. I have barely installed any apps just to see if I can find what is causing the battery to drain. Are there any other ROMs that work with the AT&T variant of the LG V20? It seems like they haven't made any yet for the AT&T V20. I am still waiting for Xposed to be released that is compatible with nougat so I can use Amplify.

I don't think there are any roms for AT&T variant atm. I did see an AT&T user flashed the stock deodexed rom by tilde88 in rom section. Not sure of all the details though. I'm assuming you would lose some functionality...would need to flash stock kernel as well.

What is your leading source of battery drain under system usage?

Yeah definitely, I think it is a little bit too early, for me at least, to expetiment with a deodexed ROM. But I know there will be some awesome developments coming out soon. I was so happy to see that a root was figured out for the V20 so quickly after it was released. Until then, I will keep experimenting with the stock ROM.

Hi Swizzle82, thank you for the reply. It is kind of difficult for me to pinpoint what the leading source of battery drain is because the apps seem to bunch all detected processes and wakelocks together. I know that Call Services & Android System show up on top a lot of the time, but since I factory reset the phone today, the stats are minimal compared to what I previously had. WeChat also uses resources, but I used that app all the time on my Note7 and previous phones, even more than I do now, and it never caused a problem. I attached some screenshots from GSam, BetterBatteryStats, Wakelock Detector, and CPU Spy Reloaded., I don't know if they will help, but just switching between those few apps and taking some screenshots over the span of 6 minutes, my battery percentage dropped from 79% to 76%.

I had android system for a while killing me.. I factory reset and setup every app one by one with no data transfer or anything. Installed every app like it's first install. I charged it til it reached 100 percent, with the phone plugged in, I went to data/system/batterystars.bin and deleted that file and rebooted. It was a long process but it hasn't been an issue since. This was when the phone first came out last month. Never knew which apps data it was but it is gone now.

That sounds like a good idea to try. I will do this today since I already factory reset it yesterday. I would rather do it now before I get further into using it again. I have not heard about this until you mentioned it so maybe there is an issue with app transfers with the V20 causing it. The battery does seem to drain less than before, but it seems like there are still some issues. Thank you for the suggestion!

If you followed did the dirtysanta method, make sure you flash the Konverged kernel for the H918. Or Tilde88's 5.1 kernel for the H918. It worked wonders on improving battery life. Also make sure you disable Lookout - that drains a lot of battery it seemed to me at least. I usually get about a day and a half of battery life when I use my normal amount (which is honestly quite a bit).

Okay, thanks for letting me know! I have not even looked at those kernels thinking they weren't cross compatible with H910. I am going to try it right now with the dirtysanta method. I will disable Lookout, as well. There are a ton of apps that I never use that drain the battery. I will let you know how it goes :good:

No, I had the Note7 before getting the LG V20. Before that I had a Note 4 and a Droid Turbo. This is my first LG phone and I really do love it. I actually like it more than the Note7, the only problem I have is the battery. I do think that factory resetting and manually installing the apps instead of restoring them will help, and using the Konverged kernel seems promising, from what I am reading.

Yup I always start fresh and install apps manually anytime I reset my phone. I think it's always nice to start fresh - even if it is sometimes a bit inconvenient to go through all the apps you've installed and choosing which ones to install. Hopefully you get it all sorted out!

Okay, I just factory reset the phone, rooted it with DirtySanta, and flashed the Konverged kernel and the phone is NOTICEABLY faster and smoother! This is great! Each time I reset the phone, it had noticeable lag. I just figured it would go away over time, which it did, and that it was because it had to load and download everything since it was fresh. But with the Konverged kernel, it has none of the lag and is silky smooth! Time to manually install the apps I want and disable some stuff I don't need. I will update you guys after I see how the battery is with the new setup Thanks a lot for your help, I really appreciate all the input!:good:

I need your help! I changed the screen cover sensor to off not realizing that I would not be able to turn off the static after rebooting my phone since the sensor is off. Would somebody please post a few screenshots showing how to navigate to the screen sensor settings so I can tap my way there and turn it back on? I am trying but there is no way to tell where to tap with all the static. Thank you!
Nevermind, I fixed it! I finally navigated to the second screen settings and turned it off when the screen is off and that got rid of the static after I turned the screen off then on again. Note to self, never do that again LOL.

Wow I'm fairly impressed you managed to do all that with the static screen haha - glad to hear it worked out for you in the end.

Get me your stock system.img and boot.img, and I'll make you a modded ROM with a custom kernel!

Haha yeah, I never knew something like that could cause such a huge problem. Now I can't seem to find what I did to cause that in the first place. I have been looking through all of the settings and can't seem to find anything that affects the proximity sensor. On top of that, the screen rotation stopped working, it will not rotate when I turn the phone to the side to type. I have toggled all of the motion and second screen settings, calibrated the motion sensor, and nothing is affecting it. When I turn the main screen off, the sensor does not shut off the second screen when I cover it with my finger, and the phone does not recognize when I rotate the screen. I am kind of at a loss on how to fix it.

Hight CPU and battery usage on idle system; restarts don't help

I've got a problem with my S8 which is running latest, official, non-rooted XEO firmware. Specifically, it uses battery like crazy and heats up whilst doing nothing. This smells like a virus / malware infection or just... well, the last update was in December 2021 so it's also possible some system component is wonky OR... <shivers> some rootkit? I'm generally rather careful when installing apps, most of which will be coming in from official sources (Google Store) or at least fairly trusted sources.
Every so often I'll get a warning that a system component is using too much CPU and I should restart the phone - which obviously doesn't help at all. Also the battery drain is reported primarily by Android System and System Core (29 and 15% respectively). Battery usage stats generally don't add up because the listings don't add up to 100%. :/
I know the S8 is an old phone... and I know there are probably steps I should take prior to asking here - like a factory reset. But I'm really sceptical of doing a factory reset simply because I've got so much stuff on the phone that, while not impossible to backup, is certainly annoying (authenticator or banking apps for example - and I don't think the standard backup tools like those available from Google or Samsung backup such apps).
So I'd rather try some solutions or methods of dealing with the damned thing without resetting the phone first. Is there anything I can do?

You need to find the root cause. It may be a 3rd party using one or more of the Samsung system apps running under Android services, lol Legend for there are many... all lumped together.
A firewall with logging can help. Karma Firewall is what I use, uses almost no battery. Being rooted you have more options... use them.
Malware is always a possibility.
3rd party apps can cause hell. I don't allow any social media apps on the phone, ever.
Try in safe mode... if things calm down it's likely a 3rd party app. If so start going through the installed apps.
Clear system cache.

Sorry about the root thing, my bad.
If you're running on Android 9 or lower Karma Firewall's logging feature is fully active otherwise not. Samsung store>Galaxy Labs> Battery Tracker can be useful.
I use Accubattery's history page to get a quick idea of charge/discharge rates.
I use Device Care>storage>clean as well.
Make sure no cloud apps are running in the background.

Update: in safe mode the phone doesn't heat up and battery usage seems normal. So it's probably some app.
Alas, the firewall wasn't very helpful - it seemed that apps that attempted accessing the internet were your usual suspects - Play Store, One Drive or other sync apps, Vanced.
Any other suggestions on possibly nailing down the culprit?
PS. I've also decided to send Samsung an error report via the Members app - I don't know what their reply times are and I honestly don't expect much from them but who knows? Perhaps they'll come through.

Why other than maybe text messages is anything syncing? Take out the trash and go from there.
The ones that are connecting every minute or more when not open are prime suspects.
Some apps like Brave browser need to be closed out when not in use or they eat battery.
You can also try a hard reboot.

Update!
I left the phone in safe mode overnight. I mean, it seemed like things were better, so at least I'd have a stable phone.
Well, in the morning I was greeted with a severely depleted battery (went from 100 to 40 in the span of 6 hours) and I got the "high CPU usage" warning popup. The phone wasn't as hot to the touch tho.
So... Whatever is going on seems to happen also in safe mode, albeit less often? Or perhaps it's less "severe" where it doesn't heat up the phone but the drain is still there? But since safe mode is affected it's probably NOT an app, right?
At this point I'm completely baffled. Any other ideas?

Hard reset... hold power button until it powers off.
Try temporarily disabling Google play Services at night, see what that does.

OK, I'm baffled. I feel like I didn't really do anything but the phone is now running fine. Battery drain now might be better than ever!
Warms up on usage, obviously, but when idle it's nice and cool and battery drain seems minimal. I'll... leave it for a few days to see how this develops. It's very difficult to tell what the heck's the case here.

Retrace what you did. Reason being you may need to do it again. Really most times all you need to do is just "play" with it a bit (a lot). Almost impossible to crash a stock load, so explore and learn by playing with it. You are what you load and download; be careful with 3rd party apps they are the biggest potential hazards.
Once you have a fast, stable OS that's fulfilling its mission, let it be. Don't update or upgrade it.
Updates can and do break Sammy's. This N10+ is still running on Pie, current load is over 2yo. Rock solid stable and it runs like a bat out of hell with minimal maintenance. Security isn't an issue.

Kill wittle bixby... you read it EULA?☠
It's more than one apk though. Takes a while to optimize a Sammy the first time
Well... if it's set up and used right Android 9 will run securely in the real world. No saving dumb bunnies anyway; they'll still get tagged even with the latest version
The proof is in my hand. Loaded over 2+ years ago and this N10+ UI version 1.5 is running clean like a bat out of hell. If I do get malware I can't erraticate in an hour or so, factory reset and change passwords.
My data is redundantly backed* up 4+ times, plus the onboard SD card used as a data drive. I'm ready to reload right now if I have to...
A malware forced reload is still less trouble than constantly updating and having the updates screw things up. That means more troubleshooting, finding new work arounds and still maybe needing a factory reset on top of all that. No.
Not vaxed either... not buying the hype.
*critical data must be redundantly backed up or sooner or latter it will likely be lost. Never encrypt data drives as you are the most likely to be locked out!

Oh I'd love that - but it's a system app and removing those without root is kind of... impossible? I can look into disabling it completely however - I never use it anyway. Since it's not a single app - any chance you got a link to the list of apps that need manual disabling?
Anyway, I'm still getting those damned warnings. The phone isn't constantly hot however, which is some improvement.

Package Disabler kills bixby proper.
You can also disable it with an adb edit. That's one of the first things I do.
Bixby is a hot mess best dump along the interstate... like Google Assistant it needs external servers for many of its functions. I may change my mind but it's eula is like eating dry hardtack for breakfast.
