I haven't used the fingerprint sensor at all. Updated to the latest October 5th patch. And these are my stats.

Download AIDA64 and check it, the first 4 cores should idle on 633Mhz, not 1401Mhz.

6 hours of SOT isn't bad. There doesn't seem to be a problem on your screenshot...

Yes the little cores stuck at 1401 MHz,

But it's random like i already said.

[Xiaomi Mi A2 / 6X Questions & Answers] MarXDroid:
Huh its fun. Ive been using miui for 3 years ang went through stable, weekly, alpha, but even on weekly builds with lot of bugs i never have major bug like this... so if I didnt sell my old Mi4, I would choose it over Mi A2 now... :rolleyes:

No issues on 6/128 version

On my new a2 6/128 Version with goodix sensor there is no issue with the CPU. Battery runtime is also pretty good.

I received the device on the day, the second October update got released.

I use the fingerprint to unlock since that day.
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
It only recently got recognized on Google issue tracker. It's now assigned. It will be fixed soon. The max Cpu frequency bug got fixed shortly after it got assigned by devs on Google issue tracker.

I think I've fixed the 1401 bug myself. It only happens to some people because it is triggered by certain apps. Ever since I deleted my 3rd party launcher I don't get the bug. The other day I installed another Lau Cher and immediately I got the bug again. I've deleted the Lau Cher and just used stock Lau Cher and haven't had it again. For me, that's what was causing it apparently. Everybody uses different apps. So something else might be what's causing it for you. Some guy on forums said he gets the 1401 bug every 3 hours. Must be some apps he is using frequenly. I've gotten it twice in 16 days. only on the times I used a 3rd party launcher. So as long as I use stock launcher I'm not getting that bug
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
I have the bug and im not using any launcher
[Xiaomi Mi A2 / 6X Questions & Answers] ns6000:
but he didn't said it's always launcher, he said some apps, in his case it was launcher...
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
mi a2 is the most buggy and battery trash phone ever
[Xiaomi Mi A2 / 6X Questions & Answers] Lunatiic:
Say it for yourself, it has been one of the best phones I've ever owned, coming from Sony, Samsung and Motorola. While Motorola almost never fixes bugs in production, Xioami fixed the CPU bug (for the majority of users) in a month after we reported it correctly on their bugtracker.

I get around 6h of SOT and 2 days of usage. Phone is fluid, runs cool, camera is great (much greater than Motorola's flagships which costs up to 3x more), build quality is outstanding, we've been getting security updates on point. I can't complain about Pie update because it took Motorola about 8 months to release Oreo for their Z flagships, so I'm fine with Xiaomi taking till the end of the year, Samsung usually takes even more.
[Xiaomi Mi A2 / 6X Questions & Answers] ns6000:
i'm planning to buy this phone, could you please confirm or refute if the battery drain (which may or may not be related to that fingerprint sensor) is still a problem or if any update managed to sort it out?
[Xiaomi Mi A2 / 6X Questions & Answers] Midomad:
I have the bug with no modifications,all stock,too.

I don't think apps will cause that,

Anyway, that wasn't the cause for the first high CPU freq bug..
[Xiaomi Mi A2 / 6X Questions & Answers] Lunatiic:
Me and all my friends which own the Mi A2 ( 4 in total ) had the CPU bug until the second october update (V9.6.15.0). None of us have had the CPU bug again, but we all have the Goodix scanner, so I can't speak for FPC phones.

So the battery drain is not a problem since the second october update for us, but as I can see here, some users are still reporting it, which is something to consider if you are willing to buy it.
[Xiaomi Mi A2 / 6X Questions & Answers] ns6000:
thank you, as i understand it, original bug was specific to the Goodix scanner (or at least that was the consensus in the beginning), there is thread over at mi.com (which i cannnot post due to new account here) that seems to agree with you...
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
Not exactly caused by apps, but triggered by them. Maybe some background process getting stuck. Ultimately its a flaw in our phones software, but it wont happen if you dont use certain apps for now, until xiaomi fixes this bug. If it had nothing to do with apps, everybody would have the bug, like the max cpu bug. Every single goodix user had it. This bug is present on both goodix and fpc, and some people have it, some dont. I got it 6 days after 2nd october update, stopped using the launcher, didnt get it again for like a week or so until the day i downloaded said launcher agian. And i have been checking CPU Z multiple times every day. With the apps that im currently using, i dont get the bug. Some guy reported he gets the bug every 3 hours after reboot. He probably frequently uses a certain app which triggers this. Im not getting the bug at all now with the apps im currently using.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
this is the wrost xiaomi phone, battery is ridiculous, i had in my life like 40+ xiaomi phones, and this is the worst, now i recomend who are looking for buy, just buy an pocophone or if u are in a budget buy an note 6 pro, skip this trash mi a2
[Xiaomi Mi A2 / 6X Questions & Answers] ns6000:
Pocophone is twice the price of A2 here and it's MIUIed, i'm interested only in Android One, so my choices in Xiaomi phones are A1, A2 and A2 Lite. I like everything about A2 but the bug. Phone is not for me, i've got LG G6, which has only slightly larger battery (3300) and it's fine. I don't think that 3000mAh is particulary small, it's average and i don't expect anything special but nor do i expect anything awesome.
[Xiaomi Mi A2 / 6X Questions & Answers] Lunatiic:
So why don't you just SELL it and buy a Poco or whatever you want instead of spamming how much you hate the phone in XDA, specifically in a topic where people come looking for real information, and most of what they find is whiny people claiming for attention. If you are so desperate to show how much you hate the phone, post if on facebook, create another topic on "Guides, News and Discussions", create a Telegram/Whatsapp group so you can invite other haters and all of you can hate together, but don't spam a serious thread where we are trying to help and inform Xiaomi of the real problems of this device. Make us and yourself a favor and get another phone so you can spam other phone's xda forum. :good:
[Xiaomi Mi A2 / 6X Questions & Answers] ns6000:
i'm sorry but didn't you mistake me for "juninhoak"? i actually love the phone and i'm just trying to find out if the bug was fixed or not...
[Xiaomi Mi A2 / 6X Questions & Answers] Lunatiic:
Yes, already corrected the Quote. Sorry about that, I'm tired of coming here to see real discussions and finding only people whining instead of trying to contact Xiaomi, opening real bug reports on miui forums, and etc.
[Xiaomi Mi A2 / 6X Questions & Answers] ns6000:
it's ok, i'm watching mi.com forums and bugreports also but they are kind of dead compared to xda...
[Xiaomi Mi A2 / 6X Questions & Answers] Amr1th:
But this was exceptional. Recently I've been getting SOT of 4hours. It actually varies, if I use just WhatsApp and browsing I'd get a lot more than what I get if just watched videos on YouTube or Instagram. What constitutes as really bad SOT?

I know this could be silly, but does downloading Aida64 trigger the cores to act weirdly?

How often do you get the 1401 bug?
[Xiaomi Mi A2 / 6X Questions & Answers] Mixz1890:
Guys....If you want the 1401mhz bug fixed, go to http://en.miui.com/forum.php?mod=bugfeedback&fid=5&page=1 and post the bug report. I personally don' have the bug but whining here won't fix it. Once people actually managed to properly report the Goodix FP sensor bug there, it got fixed quite fast Imo.

EDIT: Oh look, someone already made a bug report with not that good description http://en.miui.com/thread-4437852-1-1.html You guys that have the bug might as well go and confirm in the thread and explain how you are getting it.

Also reporting the bug to Xiaomi will get it fixed faster and already one of the threads on issue tracker about this bug got closed because they obviously couldn't reproduce it on pixel devices so go to MIUI forums....
[Xiaomi Mi A2 / 6X Questions & Answers] wquayson:

[Xiaomi Mi A2 / 6X Questions & Answers] nbaptista:
The November update was only a security patch!
[Xiaomi Mi A2 / 6X Questions & Answers] theguy:
The 1401 bug can take time to actually show. I have gone 16 days without it showing (before having to restart for update). Prior it has shown after a few days. So it is not very clear what is causing it.
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
Must be some app. When I stop using a 3rd party launcher I don't get it
[Xiaomi Mi A2 / 6X Questions & Answers] theguy:
I have never used a third party launcher so that can be ruled out... Unless there is more than one app that can trigger it, in which case maybe.
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
Of course there's more than one app that triggers it. I stopped using the launcher and didn't get it until the day I decided to download the launcher again (got it minutes after) after 8 days of not having the bug. Now it's been over a week since getting it because I uninstalled the launcher.

Some guy says he gets it every 3 hours. And some people don't get it at all, despite having the exact same hardware and OS version. So clearly it's either an app or setting some people have that is triggering this
[Xiaomi Mi A2 / 6X Questions & Answers] nbaptista:
I did a reset and still having the bug. So isn´t an app!
[Xiaomi Mi A2 / 6X Questions & Answers] Lunatiic:
Maybe it's region related, like timezone, network frequency, carrier aggregation, language, voLTE (My carrier doesn't have voLTE, maybe yours does) and so on.
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
you did a reset and then downloaded apps right? so it is certain apps. Maybe its even your CPU info app. I use CPU-Z and its fine. Its either an app or a setting. Ive had it twice since the october OTA, and only when using the launcher. Ive never had it without the launcher. For other people its probably other apps they use. I dont have many apps... Some guy said he got it once in 16 days, another said every 3 hours. Keep on mind if happens on both FPC and goodix,, so its not a hardware thing, and we have the same exact software, except for apps and settings. So thats whats triggering it. Or else it wouldnt make sense for some people to get it every once in a while (when they open a certian app they dont often use), and for others it happens all the time. And for some it never happens cause the apps they have dont trigger anything
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
this bug is really random, i haved in 2 days in a row, and in the third day i havent, with same apps and same use
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
no such thing as random bro, you just cant seem to identify the trigger
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
i got the bug again, after 4 days
[Xiaomi Mi A2 / 6X Questions & Answers] nbaptista:
I did a factory reset today, didn´t install any app, no fingerprint, and the bug appears again!
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
how do you know the bug is appearing if you didnt install any app???? did you use CPU-Z?

maybe its a setting. Did you restore from backup? or set device up as new?
[Xiaomi Mi A2 / 6X Questions & Answers] nbaptista:
I instaled CPU Z after the reset . I set up the device as new.Maybe a setting how?
[Xiaomi Mi A2 / 6X Questions & Answers] ilgreco112:
Well 6hours of SOT is good for a light use on 3000mah battery

Yes if you watch videos on YouTube battery will burn fast and 4hours is still "normal" I guess

Videos / 4g / GPS are what uses battery the most so not using them is what will make your device last longer.
[Xiaomi Mi A2 / 6X Questions & Answers] geronimo_2:
I can confirm on my new A2 (4/32, blue) I have a 1401mhz stuck bug.

The last two weeks I didn't notice any problems. Today, as soon as I installed the last update after a couple of minutes the frequency doesn't go bellow 1401.

After the Nov update still can feel the heavy battery drain.... May be due to the tiny battery provided, battery life is really short with this power sucking SD660 cpu.
[Xiaomi Mi A2 / 6X Questions & Answers] geronimo_2:
what do you mean short?

I get 2 days using 3g/4g during day (during night on off). wifi/gps on off. BT sometimes on when using earphones (around 1h per day). brightness 10-20%.

what I notices is that viber is the most power hungry on my device. I don't even use it, it's just sitting in the background and it's always on the top of the list under battery. I don't know why. battery optimization on, background data on off.

also I very rarely get 1401mhz stuck bug now. If I notice it I just restart the device and I'm back to normal. I still didn't figure out what sets it in motion. I don't use fingertip reader, never did.

that looks like the dialer app icon, take a backup of you contacts just in case and do a disable/reinstall updates on the dialer application, check the settings too maybe it's getting stuck tryng to sync or smth weird like that

check that you didnt deny any permissions on apps with those 2 icons ( the blue contacts and play services puzzle piece). you can check on settings, apps, show all, ... menu show system and check each one that has those 2 icons for weird restrictions...

I'm here with same pattern on Lineage OS 18.1. My little and big cores are stuck at min frequency of 1401 and 1747, no matter the governor I select. The problem just "appeared" (or I never noticed it before).

I'm hoping that the ota (i never applied them) will solve the problem, otherwise I'll try to clean flash another room.

Otherwise...

Any suggestions on how to apply ota preserving magisk + root + twrp? Any suggestions of different kernels and how to flash?
