ROM + Kernel or other software combo to prevent battery drain while on video call? - Nexus 6P Q&A, Help & Troubleshooting

Hi. Is there any rom + kernel combo or any other software related way to get the battery to charge while on video calls or at least hold the charge? I'm using WhatsApp/Messenger while charging and the battery goes down still. It doesn't happen to me on my Mi A2 or Nexus 5X. Is it just a CPU issue? Thanks.

in which ROM you're facing this?

I'm facing it in any nougat+ rom or higher. Both stock and custom. I'm trying to find a decent marshmallow rom other than stock (cause camera freezes on my side only during calls). I found Chroma but opening WhatsApp sometimes causes Reboot.
Edit: Is it just me or does the search function not work anymore. I'm trying to find any mentions of stuff in specific threads and I always get no results; even when I'm literally on a page that mentions it. :/

Some problems in cm11

a GT-I9500 device and I just installed the newest cm11 nightly version.
I noticed this few problams:
A. Overheating most of the time.
B. Battery drains very fast.
C. Camera doesn't work.
I know that those problams are familiar to everyone but I wonder if there are ways to easily fix at least the first 2 problams... Maybe there is a better kernel?
Please help me
I also have a probelm with the front facing camera. The standard camera is working.
Underclock your cpu to 250-1200mhz. This will dolve the heating and battery drain issue.

Use this apk to solve the camera issue. Tap it once and start google camera or any other camera app.

CM 12.1 Nightlies discussion

So i finally gave cm 12.1 a chance because it's been rolling for a while now... and i was actually pretty impressed. The one issue i couldn't deal with is the bluetooth audio playback in my car. Basically it was playing too fast, then pausing every 10-20 seconds and then continuing to play too fast again (also at a slightly higher pitch). I was able to temporarily fix the problem by turning bluetooth off and on but it came back. other than this i didn't see many issues and thought it was pretty good, but for no i'm going to go back to stock until this issue is fixed, i did find that it was already reported to the cyanogenmod team and they are already working on a fix so i'm waiting impatiently until it's fixed and i'll probably be moving from stock kitkat as my main rom to cm 12.1. How has everyone elses experience been with cm 12.1 nightlies so far?
What doesn't work. (if i missed something here post so i can update)
- saving 4k video (1080p works tho)
Battery life ?
- used to be terrible but it's almost as good as stock now but with better performance.
hey
i would like to use CM as i was doing that on my Moto G. the questions I have to users of the newest CM version:
- does quickcircle, google text-to-speech, intelligent screen (LG app) features work?
- what is the quality of videos and pictures taken by the phone running CM opposite to android v20i?
thank you.

1. Quickcircle won't work. To make it work again you have to install a special app. Google text-to-speech works ok for me (I haven't test it too much). LG features/apps won't work
2.For me the quality of pics and videos are the worst I have ever seen!!!! (Much better in the stock LG)
My experience with CM12.1 was average. I was waiting for something better. Camera is awful in the Custom roms. Battery life wasn't the best. In terms of performance the cm12.1 is better than the stock lg.
i've only been running cm 12.1 for a few days now so i don't have alot of substantive input, i did find a fix for the bad bluetooth car audio using a macro/tasker app but i think they have fixed it in the nightly released today, i'm downloading it now it says bluetooth stream parameters in the patch notes so i wont bother sharing my fix until i try this nightly to see if they already fixed it. i'll give a better review of whats working and the camera/video quality after i have a chance to play around with it more.
by the way anything running ART instead of DALVIK cache/runtime is going to perform better but it's at the price of xposed modules and such, i'm not expert on it but i know they switched to ART cache/runtime to be more competitive with the iphone. On Kitkat and lower an android device needs better hardware to output the same performance as an iphone with lesser hardware. ART should fix that problem. If you are curious google ART vs DALVIK
*edit* yeah bluetooth is fixed with the newest nightly update... atleast for my car which is a mazda 3. (yay)
Avrage camera and bugs like video not saving after recording is main culpit to not use CM 12.1. Otherwise it is good as clean android can be.

Videos do save. It is a issue with 4K video ONLY. Switch to 1080p video and videos save just fine.

I found that myselfe, tnx. But I believe that issue is fixed already. Maybe Im wrong, but I did see in changelog or other forum. Maybe someone can test it?
I switched to stock kitkat, I love CM, been running CM since it was 10.1, the problem is that it starts really really fast and after a while CM 12.1 becomes laggy it drives me crazy, other than that is the camera quality which doesn't bothers me as the performance issue,
I guess we'll need to wait for LG to release the G3 source file but who know's when that's gonna happend
good news the latest daily added some balancing between power and battery life. I went from losing a huge chunk of my battery during work when my phone is in my pocket to going 9.5 hours at work and coming home with 94% battery. (that is alot of standby but i use my phone at lunch and have bluetooth running for about 50 minutes of driving). Basically it got alot better, i'm not sure what they did but i did notice that there is a balanced setting in battery screen that i didn't notice before. Anyways I think those who were concerned about battery drain my have had their wishes answered over the last few nightlies.

Phone encryption not working?
I've just flashed the 20150603 CM12.1 and I cannot seem to get the phone encrypted. On the reboot to start the encryption, the phone gets stuck in the CM boot animation and the encryption process never starts. Any ideas or suggestions? Many thanks in advance.
I'm on 06/05 nigthly. When I plug the phone in my computer, it's not being recognized. If I change from MTP to PTP, then it works.
I've tried going to Device Manager, and could see that my phone is being recognized as a Nexus device. I tried installing latest drivers from Google's website, but I got a message saying that I'm already on the latest version. So that didn't do anything. I've tried uninstalling that "nexus" driver and rebooting my PC, but it somehow came back when I plugged my phone in. Trying to update gave me the same message.
If I run "adb devices", I can see that there's no devices (it's enabled in developer settings). If I enable ADB over WiFi and try to connect -- it works, and I can do whatever I want. But only over WiFi and not via USB.
Tried different cable and different port as well.

has anyone experienced any new battery enhancement tweaks on the new rom?
Managed to find and disable Background Task Clear which was stopping WhatsApp from functioning correctly, only other change that I've noticed is my Elephone Quick Charger is now a regular charger.Changed cable but it won't fast charge anymore.
Anyone else finding this?
No, here always ( very) fast charger.. Before i had Asus Zenfone, this is like a rocket in comparison

Yes, I have noticed this too. My phone used to charge from 50% to 100 in about 30 minutes. It now takes an hour! I really hope they fix this!

Strange- I've installed the standard recovery, removed my SD Card and put SIM in slot 1. But when I try OTA update, it boots into recovery and says "error". Won't let me install the new update.

yes the fast charging is not that fast anymore
I turned the background task clear off, I do this out of habit anyway. Don't want to risk it preventing me from getting notifications, like it did on WhatsApp for the past 9 hours.
Not fast charging anymore.
Since I upgraded my phone to this version, fast charging is not working anymore.

Battery going up and down + reboot

Hi,
My wife's gti9505's has an issue with the battery that I cannot seem to fix. One second it's at 75% then all of a sudden it's a 5%, then it goes to 50% and some times it reboots. I don't know if this might be related but she mostly feels this happens when she uses the uber app. She has the latest official android version (5.1..), I've tried installing a new rom with 6.0 but the problem persisted. I've bought her a new battery but the problem persisted. At this point I'm thinking that this MUST be a hardware problem. Any other solutions I may try?
The reboot problem might be a power button issue.

Nexus 6 speaker issue POSSIBLE fix

I had retired my Nexus 6 a while ago due to the speaker issue that's been plaguing these devices. I decided not to sell it as it would be an issue for the next user, so I instead kept it in case of an emergency.
Certain issues have lead me to recommission the device, so I decided I'd see what's new. So far it is clear that there was never a fix, and some people swear that pressing on the speakers fixes the problem (whether temporarily or permanently). I never believed this as the only thing that seemed to fix it (temporarily) when touching the speakers is tapping on the speakers, but that seems to be related to the device rotating (which has also been known to let the volume go back up) and something within the gyroscope (something that some have brought up as well). My Nexus 6 unlike many others has the bigger problem where the volume will go down regardless of battery percentage, and it was terrible as there was never an instance in which I could truly use the speakers.
Reading around I have seen other "solutions" emerge, but never anything concrete. On a YouTube video's comment sections I saw one person mention that Franco.Kernel fixes this, for me this did nothing. On another forum I read a guy who said his issue stopped using Lean Kernel, and that it may have something to do with mp_decision. Unfortunately for me, I like to stick to the latest version that was officially released (in this case 7.1.1) and Lean Kernel doesn't seem to have made it that far. I gave up on experimenting for the sake of the speakers at this point and settled on my favorite rom which is Dirty Unicorns, using the final 7.1.1 build (somebody was nice enough to provide links as I could not find it anywhere and their official page only has their Oreo based builds). Obviously the speaker issue persisted here. At this point I wanted to see if there was a Kernel with good features and battery life and came across a thread that mentioned BL4CKB1RD Kernel. I flashed that and was a happy camper as my phone runs cooler (no difference has been made to my 4 hour average screen on time) and ultimately lag free. Reading the maker of the kernel's current set up using the kernel, I decided to copy it a bit by limiting my maximum CPU frequency to 2.5GHz and using said governor profile. I came across the mp_decision setting and turned it on just out of curiosity (I have no clue what it does). Later on, I went to watch a YouTube video and before I could connect my headphones, the video was playing...with perfect sound. I thought I was going crazy, so I let it play for a bit longer. No volume drop. I picked up the phone, moved it around, rotated it, blasted the volume to the max and still not a single drop. For literally an hour I watched videos and absolutely no volume issues. I decided to undo all kernel changes and reboot to see what would happen. Still no volume changes. I also decided to lock the CPU and GPU maximum frequency to produce more heat, still nothing. I played Subway Surfers which was a guaranteed instant volume drop, nothing. Rebooted several times more, let the battery die, speakers are still perfect. Could this kernel have fixed my issue? Maybe. It is also worth noting that before flashing the kernel, I ran a command via terminal emulator (requires root) that I read about BEFORE flashing the custom kernel, and I never rebooted my Nexus 6. The command can be found here (there was another thread that also included it but also linked to this thread):
https://forum.xda-developers.com/nexus-6/devs-only/speaker-amplifiers-nxp-tfa9890-research-t3236518
Anyone with the speaker issue should perhaps start by this command, reboot and see what happens. If not, try using BL4CKB1RD kernel and see what happens? If still nothing, try toggling mp_decision on and then test.

I just ordered a nexus 6, is this issue common? Does it affect stock rom or custom roms? I have a Moto X Pure at the moment, Nexus 6's brother, it has a similar issue where the sound cuts out when the phone is switched from portrait to landscape and vice versa but only affects custom roms. Its doesnt lower the volume though

For most the issue occurs at low battery, and the drop isn't major. I've seen some videos of people with this specific problem and I laugh because they don't know have it as bad as us with the major drops regardless of battery life. So pretty much the low battery volume issue is more common than the worse one, and you could say it is a common issue.
We had a white one that had absolutely no issues except a faster battery drain (perhaps because the speakers worked?!).

Yes.
For what it is worth, mp-decision is Qualcomm's own hotplug: it turns the processor cores on and off depending on need. I guess it may use other tricks as well, to optimize power / performance.
No obvious reason that it should affect the speakers, but you never know.
Does this thread address the issue with SEVERAL 8.1 ROMs I've used, in which the speaker phone does not function during calls... and during calls alone. I can play media just fine... IMMEDIATELY after the speaker not working on the calls. I CAN however plug a headset in and communicate normally . Just desperately seeking an answer or I guess I'll go back to 7.1.2
So now nexus 6 is running pie roms nearly perfect . Unfortunately this sound problem persists… it is truely fristrating
So is there any kernel that can fix it in pie roms? Thanks
I have been using my nexus 6 for a couple of years now and had the speaker issue about a year ago and went into recovery and wiped cashe and the. Did a factory reset. Did an OTA update and everything was fixed.
Last weekend I finally flashed TWRP and then rooted with Magisk. Went to install myself5's Bata version of Carbon room running pie... Not sure what happened but had error code 7 and bricked the phone. Had to wipe it out and went though Google to get an old OTA and reflashed and thankfully got my phone back. Tried the process 3 other times and got the same result. Each time no speaker issue.
The last time I tried it I left it alone and didn't even put TWRP on it but now the speaker problem comes and goes.
5 min agot I was playing YouTube music with no issues, made a phone call, then back to YouTube and now the bottom speaker quit and the top speaker is very quiet.
Any ideas on what could have cause my issues and can someone direct me to where Ii can find more information or what I'm doing wrong on on flashing new roms?
Currently running Android 7.1.1 build NGI77B

I've honestly encountered this problem a couple times but rebooting/flashing fixed the problems. Worst case scenario go back latest Google ROM with WUG's software, then you can install TWRP, then a custom ROM like Nitrogen ROM.
Sent from my shamu using XDA Labs
I know nothing about what anyone is saying, but I would like to add that using Viper4Android, and using "eXtra loud" at "Moderate" with the max gain at 4x and the max output at 0db completely gets rid of the low volume problem. Viper works system wide so it fixes it for Netflix, etc
Hope this helps guys

Sorry for the late reply, I had to put the Nexus 6 on hold due to another issue with it. I tried your kernel with the latest official version of Dirty Unicorns, but unfortunately it does not boot. It will boot fine without flashing the kernel.

Having this same issue using the NitrogenOS Pie rom. Updated from 7.1.1 (didn't have this issue with 7.1.1).
Is it better with the Oreo 8.1?

No . I can confirm that all oreo roms got the same bug .
For me am using android x unofficial pie rom with popcorn kernel. This combination seems to fix this bug !
Try them or even try the kernel with nitrogen os rom .It may work..

Unfortunately no. Mine WAS working perfectly. The charge port broke after about two weeks after I made this thread (my luck), and after having it repaired, the problem seems to have gotten worse. For one, it no longer works in the configuration I mentioned in this thread (mind you, I did not reset it or anything). It also now varies from rom to rom, with the bigger issue now being that the top speaker ceases to function on certain roms, including the way I had it. Now, it drops volume for everything, and most of the time the top speaker will be weaker for the slight moments both decide to work.
New problem
Hi Crossvxm. I have had a Nexus 6 for two years. When I wiped it to sell it, the audio problem started. I had PureNexus.
I did what you suggested. I turned on mpdecision with BlackBird kernel and kernel auditor. I installed su terminal, to execute these commands with root access:
echo 1 > /sys/bus/i2c/drivers/tfa9890/8-0034/force_calib
echo 1 > /sys/bus/i2c/drivers/tfa9890/8-0035/force_calib
And the full volume audio came back! Videos, youtube, all working again! But, the audio in calls worked no more. So, after that, I wiped all, installed PureNexus 7.1, Nitrogen 8.1, stock 7.1... I tried everything, but the audio in calls never returned. When I reinstalled all these roms, the low volume problem appeared again, but the audio in calls never came back. Even WhatsApp calls have no audio. The microphone still works, because the other person indeed can hear you.
Do you have an idea about how can I solve it? At least to leave it usable as phone. Thank you very much for sharing your knowledge and time.

This sounds like what happened to me recently. The configuration I mentioned in the very first post worked perfectly. After taking it to have the charge port fixed, the top speaker stopped working, and you could not hear the top speaker at all during calls. I thought the store broke it, but after giving up using it for some time, I realized that it would randomly try to output sound from the top speaker. After starting all over (flashing back to stock and flashing my same configuration again), the problem changed to where the top speaker was very low in sound when both speakers felt like working. I flashed the latest Dirty Unicorns based on 8.1 along with Popcorn Kernel by athulele but unfortunately it did not boot (as mentioned in his thread, the kernel is Lineage based).
I gave up on the Nexus for a few more days. When I decided to give it another go, I flashed the latest LineageOS (along with root for it via their own separate flashable zip), flashed Popcorn Kernel, installed Kernel Adiutor from Google Play (yes, it's spelled that way), installed the Terminal Emulator for Android and ran the command as well as checking the kernel settings to ensure MP Decision was on, capping the max frequency to 2.4Ghz (feels much less hot) and making sure everything was set to "set on boot". Unfortunately it did not work. The only way I got it to work again was to give up again, flash back to stock and flash Lineage and Popcorn Kernel exactly as I explained in this second paragraph.
So why did it work this time around? Everything was done the same, what could possibly make it work? I have a theory. When it was taken to the shop for repair, the battery died since it was already at 20%. As you can see I mentioned a few times "I gave up" on it, meaning I stopped bothering to fix it, and eventually it would run out of battery mainly from wifi and notifications. Every time it was dead, it was usually dead for at least 24 hours. Each time around, the issue would change. I don't know what it has to do with anything, but I do believe it plays a key role. Try letting your battery die, charge it back up to 100% and then try the process from either paragraph two or from my original post. After it began working again, I abused the heck out of the speakers, rebooted the phone, tried calls, etc. all without letting the battery die and it has not stopped working. I recently sold it as is and was contacted by the person who purchased it who was confused as he did not experience any sound drops either. He was originally buying it to replace the screen on his but decided to stick with mine since it was working perfectly so far.
