Development [ROM][12L][OFFICIAL] PixelOS [AOSP][STABLE][12/08/2022]

So that's the reason why the ROM strangely wastes so much battery, hope the maintainer fixes this issue

To my understanding yes, the temporary fix for this is to restart the device when the frequency locks.

I think I found the issue causing high battery drain as well as high temperature. I was monitoring battery discharge rate and CPU usage using Castro. I found that the 2nd cluster of the cpu just locks at maximum frequency all the time causing high temps and battery drain, While the 2nd cluster's frequency was variable I was getting low discharge rate and better temps. I tried to find application that might be causing the CPU to lock at max freq but still no luck, I think it's a kernel issue and not the rom but then again I could be completely wrong. I've attached screenshots for better understanding.

this is a well-known problem with this phone, happens with any rom including stock, usually after turbo-charging but not only. probably a firmware bug. I don't believe anyone found the actual cause yet

Wait, the battery drain problem is a firmware issue?

it happens on any rom and with any kernel. could be also a kernel problem that nobody has solved yet, of course -- what's the practical difference...

So after rooting and installing fkm I was able to control frequencies of CPU on idle which increased the battery and decreased temp tremendously, I'm pretty confident that the issue may be the kernel.

that would not be surprising as a few people in the PixelExperience thread have pointed out to have fixed the battery drain by changing to the vantom kernel

The CPU results are from the stock kernel comes with the rom which is vantom

I have also a battery drain issue, fully charged my phone than let it all the night with AOD activated and the battery decreased to 50 % in 8h of pure inactivity (except AOD)
hope dev will fix this issue soon cuz it's the best rom out there for RN10P
thanks aryan

I'm on the latest build and i have two issues ! Sometimes the phone is really slow and i have to reboot it so it can be fast again ! ANd whenever i'm calling someone with a wired headphone the sound quality of the mic is terrible ! The person hears me so bad and with a lot of ambiant noises ! Please fix those two issues ! Thanks

Hey, sorry to bother, the rom is absolutely great, just great! But i ve found one serios bug... sometimes, when you press the power button to wake the screen it stays black, no matter you double tap, you press, nothing works, just a hard reset work and fixes the problem until it appears again. While the screen stays black, you can hear the taps and haptic feedbacks coming from the phone while you try to light up the screen. I do not know what it could be, followed the guide step by step no other problems.. just this one

I was on a Arrow OS A12/11 and Pixel experience before reverting back to MIUI 12.5 and now I'm on MIUI 13. Want some taste of good ol stock android back. MIUI 13 has reduced battery life and smoothness is also reduced. I wanted some feedback on how the haptics and idle battery drain is on this ROM (as I see some issues reported in this thread). Also is there any sort of screen flicker at low brightness?

Haptics are good and the intensity of haptics are customizable aswell, idle battery drain is amazing I usually have around 2-4% overnight drain (6-8 hours) & finally I haven't noticed any flickering and even if somehow you encounter that there is anti-flicker mode hope this helps.

So, which FW should I flash for the latest may 13 update? 12.5.9 or 13.0.8? In the OP 12.5 is the recommended, but on the website it is instructed to flash miui 13 fw.

+1 to this. Also since I am on MIUI 13 already, do I need to flash the MIUI 13 firmware as well before flashing the ROM or not?

My bad, I did not update the original post. You need the MIUI 13 firmware

Hi, I'll look at the AOD stuff for the next update (after the June one). Thanks!

Hi. The kernel and a few other stuff were changed in the June update. Let me know how it is with that

Hello

Sorry for the lack of updates here on XDA, but I have a new build to share today.

You can download it here or here.

The source changelog can be found here
The device changelog can be found here

For this build, I have switched to EROFS (Enhanced Read-Only File System) as well as F2FS compression. What does this mean for you? In short, things will be faster on this build.

Due to the EROFS changes, you will not be able to directly modify the system files yourself (As in the name, it is read-only). You will however be able to modify those files by using magisk and its modules.

Due to the change to F2FS compression, I recommend clean flashing this build with the PixelOS recovery or the provided OrangeFox recovery (It will only work if you flash the ROM and format data through those two recoveries). A dirty flash might work but it is not tested nor is it recommended as F2FS compression really helps overall.

Both these changes combined make for a much faster and smoother experience. I have also updated the original post with the required links and flashing steps. Enjoy the build

Nice gotta flash it soon
Can you add AOD schedule and AOD on charge option?
Always thanks for the rom!

 

[cmmike1]

is there a proper backup solution? or can any of the recommended recoveries at least decrypt /data? I wasted enough time getting the phone to work as I want and making sure all the auth/2fa/etc stuff works just 2 weeks ago, not enjoying the thought of slogging manually through all that again at all.

I realize people making custom roms don't owe users anything, but a tiny bit more consideration and respect for your users' time would be, you know, nice? some people actually _use_ their phones, not just rom-hop for fun.

at least have the courtesy of holding off on clean-flash-requiring changes until a full backup is possible, especially changes like this, which promises some vague "performance benefits" and does not seem critical at all.
