Battery issue or Custom rom issue or something else ? - Xiaomi Redmi Note 7 Questions & Answers

So i installed PixelExperience 12 on my Redmi Note 7s (Lavendar), well the phone randomly shuts down and only turns on if i put it on charge, but while charging this doesn't happens.. It also used to occure on MIUI 12.5 as well but not as frequent as with PE. Is this a battery problem or something else ? Please help...

Never happened to me on MIUI 12.5 but maybe you should try and post here as well: https://forum.xda-developers.com/t/rom-12-lavender-pixel-experience-official-aosp.4383539/page-2

Battery drain after charging

This is a bug, that I have nearly since I have my Redmi 3S. (So nearly since august.) I used global developer and xiaomi.eu weekly, but I noticed this on both. In battery stats "Android" keeps my phone awake immediately, after I plug out the charger and causes a high battery drain. The only solution is to restart the phone. It makes me crazy and this is the main reason, why I'm thinking to change to Lineage OS. Did anyone else noticed this bug? Do anyone know, how to solve this? Thank you for your answers!
Same as me
I have a same problem too in miui 8 7.3.16. And i'm thinking about to change to RR OS

Which variant of Redmi 3S do you have? Mine is the 2/16GB version (2016030).
I forgot to write, that I can't get rid of this bug, if I make a clean install, then I will be bug-free only until I install the next update. Maybe if I install the stable version, do a full backup with the built in app and do a clean install every update?

Facing the same problem in 7.3.16. I guess its the rom issue. I'm planning to downgrade to 7.3.9.

its a very known issue caused by "msm_otg"
it only happens when u charge your phone fully 100%
charge it to 99% and it wont happen

Thank you for your tip. I will try it.
Charging until 99% didn't solve the problem. But after some (more) googleing it looks like I found the solution: Until now I charged my phone using the charger and cable I got with the phone. Now I just charged my phone with an another cable, and there's no wakelock! By the way it's a Sony cable. Thank you for your answers!
Edit: Sorry, it looks like I didn't found the solution. I did a bugreport formerly, please confirm here: http://en.miui.com/thread-500015-1-1.html
Did anyone try stable ROM, who noticed this bug? Is this bug present on stable ROM?
I'm facing the same problem in MIUI 8 7.6.29 weekly updates... Did anyone got the solutions?

Well, if the source of your problem is the same as mine, then as I wrote, the only solution is to reboot your phone, because it's a kernel level problem, so apps can't help this. But if not, you can try this (I haven't tried it, for this you need unlocked bootloader and TWRP.) or the app named ForceDoze (For this you don't need unlocked bootloader, TWRP or root. But you need a PC with ADB drivers installed to activate this app.).

Moto X play Battery Suddenly dead, like from 60 % to 0% and power off.

I m facing this problem in all N 7.X roms, Even returning to stock firmware till problem exist. My phone turnoff on any present like 60 % shown and suddenly its shows 0 % and power off and when I trying to start its shows battery drain but when I connect charger, after few seconds its show 60 % battery then I am able to start devices.
Kindly suggest solution If anyone have.
Thanks in Advance.
(Sorry for my bad english)
Hi, I've faced similar problem 2 or 3 times, although for me it was around 20-25% (on stock MM). I don't know if it's a solution but seems it helped for me: charge a mobile just a bit so it turns back on, then use it until it really goes to empty battery and charge it to full.

I can confirm this. ALso around 20-30% or lower. Often will crash out right when I wake the phone up and often when using the camera. Using Lineage OS 14.1 nightly. Haven't figured out a solution, but restarting the phone will bring battery life up to where it was and often will allow me to finish the charge, or at least get me to a charger. Maybe just old batteries?
Hi,
Happy to inform u all my problem is resolve with replacing the battery. As per my opinion this is the best and final solution for this kind of battery problem in moto x play

I've had the same problem with my Moto X Play since November 2016
I've had the same problem with my Moto X Play since November 2016 and today the same problem continues ... I've changed the ROM many times since 2016, but the problem continues and turns into 15% and 30%.
I have Android N and TWRP 3 on my Moto X Play and I realized that the battery had power, because in TWRP it is possible to see it. I think this problem is not necessarily in battery, but "in something else" ... it's very strange ...
I have a question: how does Android know my battery? A file? Is a software inside it responsible for seeing my battery charge?
I think that is our problem.

Have you got the solution? I replaced the battery with genuine one, but still phone is shutting off at 70-80%. I also tried flashing PureNexus ROM thinking it may be a Nougat ROM problem. But the problem is still there.
Old battery is the reason. I faced it too in 2018. Then I got a new battery. Worked fine until a few days back, when it again started shutting down on opening the camera. Don't know why exactly. Most likely it's just the phone showing its age (I bought the phone in March, 2016). But other than this battery/age issue, it's working fine. Really a very well built phone

battery problem

Hello guys, I have a Samsung Galaxy Note 4 (N910u) , I reset it a week ago and I am starting to have issues. The phone will not charger more than 70% (fast charger connected) even after 2 hours of uninterrupted charging. When I turn off the phone and charge it still shows 70% but when I remove the battery and plug it in again then the phone shows 100% charged and I am good for another day until this problems repeats. Please help if this is a hardware issue or an issue with software or battery calibration and suggest any methods to resolve it.
Used to happend to me also, but my problem was an kernel issue... So all I did was flashed a different kernel... Also I'm using custom rom btw

Step 1: Buy a new battery (Anker, PowerBear, or genuine Samsung direct from Samsung or carrier)
Step 2: If problem persists, come back and ask again
when you flashed a different kernel the problem sloved or no

hi my friend
when you flashed a different kernel the problem sloved or no
and what the best kernel i can flash it to slove this problem
thanks alot
I'm on nemesis 3.7 rom with H-vitamin 2 kernel
You didn't answer the whole questIon, Dorian...did it fix the issue?
Yes I already stated that it fixed my issue in first post
thanks alot my friend
iam install the Kernel you say it and my battery now perfect
Nemesisroms 3.7 fails
I installed that rom but I have had problems.
1. I can not calibrate the fingerprint lock I tried it a thousand times and I finish the steps and when I try it does not work.
2. 3 days ago the phone when I will use it after the inactivity of the night the lock screen turns on but does not recognize the touch. Step to remove the battery and to place it and to turn it on it works well.:Rodar los ojos
I don't think nemesis refined is meant for ur phone model... You could try a different rom that is for N910u, I'm using a N910h... So two different models.... You could also try a new battery and see if problem goes away
Can one of these extended battery kernels be flashed with a stock ROM? My phone is really turning into a laggy POS, I wanna do a custom ROM that's faster and minimalized but I'm worried what ROM can be flashed with what kernel since I haven't felt the need to flash or bake my own ROM in like 3 years since getting my first Note 2...this 4 is a step forwards and backwards.

Massive battery drain mi 9T

Hello guys! Yesterday I updated to miui 10.3.15 and i experienced massive battery drain overnight from android os. Last night I charged it full 100% and in the morning it was 19%. And this is with only 20 minutes of SOT. What may be the cause? Airplane mode is on, because I am on vacation in country where i cannot use roaming. I deleted the cache and rebooted the device and I think it is fixed but i will know when I fully charge the device.
try new beta android Q, is awesome for battery life
"9.9.26 - First MIUI 11"
Install Europe version ?
Im on mi-globe 9.9.26 and i suffer battery drain and heating issue
The pix for reference
This happened to me once. I believe is not a battery issue it's more like a process keeping wake up and eating the battery. When this happened to me I reboot the phone and charge it again and issue not happened again.
This keeps happening to me every few days.
I had to manually disable autostart for all apps. And i did not even know which ones I need and which ones I don't.
But it did not help, it keeps reapearing.
Same
This happened to me a few days ago and happens again every few days. I don't remember if it was after the installation of MIUI 11 or earlier, but I would think it is a software issue that Xiaomi should investigate.
The only solution I found was to close all applications and restart the phone before charging it.
I have no issues, my advice is whenever installing an os update it's always best to do a factory reset in order for the phone to run at optimal performance. When i updated i did not reset my device but i made sure to clear all app cache and reboot the phone after update. My SOT is normally 8-9 hours, also i made sure all my apps are up to date and their are no background apps that are draining my battery.

Xiaomi A1 Charging and battery drain on AEX v7.3

After rooting and flashing AEX v7.3(android10) on MiA1, the battery got drained too fast even though i restrict battery usage and data on every apps and system apps. I use fast charger yet its showing "Charge Slowly" and will takes 2days to completely fully charge the battery. Is it the rom? I charged it the whole day yesterday and still its only 37%. Can anyone guide me or help on how to fix this issue?
