Alright everyone,
Some details about my phone before we begin-
I am a moderate user. I play some games, check emails, text and that's about it.
My phone is NOT rooted and obviously I am not running a custom rom, or a alternate launcher, and I haven't really modified many if at all any settings.
So, that being said I am experience some sever kernel wake lock issues form bam_dmux_wakelock for the past week or so. As you see in my picture, 6 out of my 7 hours of up time (off charger) has been kept from deep sleep, therefore destroying my battery time.
Today I have maybe 30-40 minutes total of screen on time, but not nearly the 6 hours of non deep sleep time.
I've turned off "okay google" detection, disabled wifi when screen is off, restricted background data for youtube, disabled google + (I don't use social media) and my brightness is on auto mode, typically around 35% when the screen is on.
If google can see this I would like to offer them a huge F you for changing the permission architecture so that gplay apps cant detected whats causing the wake-lock without root. They are pretty much forcing us to root our phones to access features locked meanwhile continuing to call android "Open Source"
Can anyone give me a recommendation on what are my options? Or should I really just root my phone, which I don't want to do (I have in the past but I haven't needed too with the G3 since it has everything I want without root)
I don't think it's Google's fault if LG makes a sucks kernel. Anyway, bam_dmux seems to be related to radios. Could it be that during those wake locks you were in an area where there is weak signal? Are you still experiencing this error after a reboot of the phone?

I've reset the phone multiple times, and have also cleared the cache from the bootloader as well. I don't have a weak signal in my area; also the radio interface is a separate wake lock code from bam_dmux. From what I read bam_dmux has to do with google background services.

Google location service may be running in the background to much too long.

I don't see a google location service only the Verizon Location Agent; there are two other services called "LocationServices" under All in my application manager, and they are both listed at being 0.00 bytes in size (?) I force stopped those anyways along with the verizon location agent which restarted anyways. I also have location completely off in my quick menu from the pull down bar, I only turn it on when I'm using GPS.
Hello.
I have an issue, and tried to investigate it but withoout success.
When the GPS is enabled, something keeps useing it. Sometimes i have to wait for some hours for it to turn itself on, sometimes it 'bugs' after some minutes.
This hapens after a hard reset (and email entered, apps updated) too.
Tried to disable all location based stuff:
- no weather widhet (uninstalled)
- no location reporting / shareing
- no gps aps running
- disabled all stock apps i can.
- user an older play services, and a newer too.
on the gps settings tab, it shows the play services, but with only in low enegy mode.
when it comes today, i tried to kill all the running apps from the app settings includeing system apps. nothind made the gps icon gone, not for a second.
Does anybody got a solution, or something to let me use the gps enabled, but without something let it user for hours?
//No root, no unlocked bootloader!
Thanks!

Dude I have a verizon g4, well on my third one and every one has done the same sh.t..i can't even use high accuracy but the other two stop it, but most apps have a hard time getting location unless on high accuracy for me so good thing I always know where I'm at anyways lol

I observed the same behaviour
Service center told me, to do hard reset and bring my phone to them; nothing usable info.
Hi guys.
I have global device version, without root, everything is default.
Sometimes (independently how exactly I use the device) it could be locked on maximum CPU frequency. I noticed this issue just, randomly. I've installed CPUZ to see more details about phone and then noticed that all frequencies in maximum (1612 first 4 cores and 1804 all another 4 cores).
Then I've installed AccuBattery to see the energy consumption and noticed that when this bug occurs, the device consumes about 210-240 mAh (with disabled all wireless interfaces surely), but after restart, when everything OK with frequencies stepping, it consumes about 110-140 mAh.
I've been facing this issue on 9.5.19.0 and the same on 8.8.16.
Have someone similar issues? Could you please install CPU-Z (or any anorher similar application) and say if everyone has locked frequencies?
Yes, I know, I've checked all background processes, I've enabled debug mode, connected via cable to laptop and.. adb shell -> top, I was seeing on real CPU activity. It could occurs randomly and then only reboot device could fix it until it happen again.
The same bug I found on the same phone in my friend. Strange, actually.

I knew this problem about 2-3 weeks ago. When you charging, it go up top freqs too
That's why I want to use custom kernel. But sometimes ( much less than stock ) locked at top freqs so I think it is Miui system policy also.
You should try some kernel manager to solve temporary.

Aha, yes, you're right. Now I sorted our everything in my mind and seems it occurs after charging.
Do you think the same issue has all people with this smartphone? But just a lot of them doesn't look on that?
But I'd say it's critical bug to have locked frequencies. Why do you think it's like "miui system policy"?
I had many xiaomi devices, only here I faced with this issue. I thought may be my phone has manufacturing defects.. but seems the bug is general on our device.
What the miui version you have?
Ah, I didn't want to root my device.. I wanted to leave it as is, as stock and don't think about all this headache, but seems the time to unlock bootloader.. Because I haven't root, so, I'm not able to use any kernel managers to reset the frequencies/governors

- I'm on Masik 2.5 with BlackBox kernel. If Kirks solve Dual app problem I will switch
- Miui system policy: I can not freeze/delete many system apps/modules after rooted. I also can not disable many Miui services/procsess ( by MyAndroidTools ). Miui also has performance mode for some purposes, can be auto activate in some cases
Does it drain battery faster? It can be caused by one of your user app. Try to remember when this started to happen, and traceback to the time you install/update apps during that period. Use MiXplorer and check the last installed app. There are apps that can triggered to mine cryptocurrency during charging, making your phone super hot and charge very slow. I am not saying it must be a malware, but it can be some apps that act similarly.
Try to boot to safe mode for several hours to check if it really caused by user app. Turn off your phone > Hold power to turn on > As soon as mi logo appear, quickly hold volume down until the phone finish booting (can be up to 30 seconds). You should see "safe mode" watermark at the bottom left corner, indicating all user app has been temporary disabled. Leave it for several hours to see if the battery still drain or the phone stay awake all the time (high cpu usage). To exit from safe mode, simply reboot.
I always found it is kind of a habit to blame MIUI for everything. I am not defending MIUI here, they bloat a lot. I also hate it and I am using RR now. But on several occassions when we troubleshoot, we found out it is one of the user app that cause the trouble, ads, or slow charging; not anything related to MIUI. Blaming MIUI won't solve the problem, only troubleshooting will lead us to the real culprit. In your case, it still can be caused by the MIUI itself. But until you troubleshoot it out, you won't know who is the real culprit.
For comparison, when still using MIUI 9.5.17.0 I can easily achieve 10+ hours SOT within 1,5 days (max is 14 hours). When switched to RR, affected by the wifi deep sleep drain, I rarely get 10 hours SOT anymore. Still in the process of troubleshooting the problem.

I've checked everything. It occurs after charging in most cases. I think that is the bug in governor. Yes, it drain battery a bit faster, but just a bit, I just calculated emergy consumption.
So, when my frequencies was locked, I just connected my phone via ADB to laptop and was looking at the "top" utility to see the load of CPU. And guess what? No load! Idle 796%. (all another 4% for top with refreshing each second and for CPU-Z ran on device).
Weird bug, actually...
I think I have unlock device and re-flash firmware via fastboot to over-write everything.. who knows where bug is hidden.
I've already done full reinstall system. wipe.. but it could occurs even during I read the book. Or just.. enable device, go to CPUZ, and frecuencies locked at max. Absolutely random event

Try not to install anything first after the wipe. Or just try the safe mode. As I said before, it might be caused by the same user app you installed after you wipe.

That's could be.
I've unlocked bootloader and just flashed the last 8.8.16 with fastboot (just had thought about it could fix something, may be some thin deep bug).
But no, after I've installed the firmware with fastboot, I've started to install all my software from Google play. And guess what? I just see in cpuz and see the same - frequencies are locked on maximum values.
Strange .. I don't use something custom, or from unverified sources, just everything from google play.
Even without games (just PUBG). All another software just social. FB, messenger, Instagram, telegram, WhatsApp, Viber, and so on. And I even cannot to see what application could cause that. Don't want to root the device. After I've installed everything and rebooted device (to reset that bug with frequencies), now everything normal. Continue observation...
Just wanted to find someone who has the same issue and at least compare revisions, installed apps and so on...to try to find the trigger which causes this issue.

That's why I prefer the troubleshooting starting from small first, before going thru the whole ROM flashing. 80% of the time, it is caused by user app. A simple safe mode or factory reset will pointed out a very obvious clue immediately.
Not all playstore app are bug-free, we just don't know what happened in the next update of the app.
While you don't state it before, it can be mediaserver bug. It is caused by the mediascan which stucked at certain file/folder during the scan and keep eating CPU cycle forever. But I've never seen it goes thru almost full CPU load. The solution is to rearrange the files/folder in your internal storage or microsd (if you have it), clean up as needed. Sometimes, a simple restart resolve the issue, but not always.
I have Whatsapp. Some users in the kaskus has FB, IG, Telegram installed; I don't see much complaint from them regarding the CPU usage, except that the IG story are cropped/zoomed (16:9 to 18:9 ratio problem). You can only troubleshoot it step by step, by installing one app at a time. It is very lengthy process and tedious. But usually you can spot which app can be the potential culprit by looking at the battery usage of them. Example, you don't use viber at all, by it appears as one of the highest battery usage.

Yes, I understand that and understand why it would occurs and tried to investigate in this way, but...
I have equals application list which I had on previous device except...CPU-Z and AccuBattery (the AccuBattery for now is removed) because of I faced with this frequencies issues.
This morning it happened again. But I just.. woke up, saw on frequencies - everything OK. Then I just.. Instagram, Telegram, Facebook Messenger and Google Chrome and no more. Then I realized that the phone became a bit warm.. I saw on frequencies - it was locked again
As it happened, I've came to office, connected via ADB to laptop and made several screenshots from `top` utility and looked a bit into `adb logcat`. But nothing... IDLE ~798%. And then I've tried to go to all apps and do force stop for ALL apps. But nothing.
I just rebooted device again...
Please look on it.. https://drive.google.com/open?id=1yXjQQ4rsF3MURh1PF0DZ1Z_Gtgc4-m4_
Just concerning about.. there are a lot errors in logcat. But I understand that.. that's ok.
But 90% of logs flowing from system processes, not from apps. But there is nothing critical.. Nothing something what could flow unstoppable text and caused over-loading CPU.
I'm afraid that it could be manufacturing defects
I event tried to re-flash firmware with fastboot (I thought that byte-by-byte flasing into ROM memory could fix some random small issues). But after flashing with fastboot this CPU locking happening again.
Actually.. dunno what to do with that. The last thought to try any custom ROM (may be Lineage OS) with custom kernel and make sure that it is just bug in Xiaomi's ROM..
And I've posted about this bug on official MIUI forum and seems this bug happening with some people.
http://en.miui.com/thread-3620931-2-1.html
Talking about me. I've flashed Pixel Experience and for now everything good. Seems that's the bug in xiaomi firmware.

Maybe that's the random issue with certain apps configuration with some users. Not all reporting the same. Seems to be related to thermal engine or CPU governor configuration. But I don't know where it goes wrong. At least you solved it now by flashing custom ROM.

I just used custom firmware just for check is that factory defect. But seems that's issue only with xiaomi's firmware.
Yes, I thought that could be governor likewise. But.. Don't think so, because this low-level things, I think, debugged and enhanced successfully by default. Seems some conflicts between system applications.
On custom ROM I haven't faced with this issue, so...
But this morning I've flashed again the global stable firmware (9.6.3.0), will see how it will going..

Yes, I've got first lock on maximum frequencies.
So, after researches.. I could say that it's a bug in xiaomi firmware. Definitely.
I also have this problem on every MIUI rom, with stock or custom kernel. It happens randomly. I have tested in 9.6.19, 9.6.4.0, and betas 8.8.23 and 8.8.30.
If I flash any custom rom the problem desapears so it must be a problem of miui rom itself.
