Redmi Note 8 Fast Charger Problem - Redmi Note 8 Questions & Answers

Hello guys. My Redmi Note 8 phone had a slow charging problem, I solved the problem by installing the Ryzen kernel, but then the fast charging feature was turned off. I activated fast charging in Orange Fox settings, but it did not improve, I installed a fast charging module with Magisk and it still did not work. Is there a kernel version you can recommend guys? Thanks in advance for your help. MIUI miuimix 12.5.4 Stable Rom Android 11 Ryzen Kernel 4.14.256

Recommend some Kernels that support fast charging on Chinese variant.
There are lots of Kernel support fast charging on Chinese variant, A11-A13. Meow, Lighting, Cara, Cryo, and so on. All of them active on Telegram, but just a few of them post on XDA. I don't know why. In case someone need fast charging on...

Quick charge doesn't work on global ROM

The only time quick charge has worked on my phone is with the original ROM that came on the device. I've tried the developer rom and global stable, and neither of these work with quick charge. Even with the supplied wall charger it peaks at 1.7 amps. All my USB battery banks charge it at that speed too. I was able to charge at 3.2 amps with the original rom. Anyone else?
Same here after updating to miui9 it doesn't work.

Facing the same after MIUI 9 Update.
Yep, I just confirmed it by reinstalling miui 8 global. Quick charge works on that one, but not on 9.

I don't get the charging rapidly message anymore on the new global rom either but ampere said that my phone was charging at 2.7A (battery was about 80% full) before it peaked and started gong down as it 90% etc....

If it's a known bug why would I report it anyways? It's already known. I'm using a forum for open discussion as that's the point of a forum.
I'll try the 7.11.6 ROM and see.
Edit: 7.11 is the developer ROM. I've already tried that one and quick charge does not work. For me it's only working on miui 8. None of the miui 9 ROMs have shown the charging current on the lock screen. I had to use a Drok USB meter to test the charge speed on miui 9 since the lock screen no longer shows the charge current.

7.11.6 has a working quick charge!
It's working for me on the 9.1.1.0 global stable rom. Let the screen turn off completely then press the power button and you should get "Quick charging, tap to view details" at the bottom. It doesn't stay there very long and changes to "About x mins until full" after a few seconds and then the quick charging notice doesn't ever seem to come back again.. It seems it only shows on the lock screen and even then just for a few seconds. It does work though

Are you 100% sure its working? I see so many posts about people experiencing the exact same issue as me. Are you still on 9.1.1.0 or did you update to 9.1.2?

Ok, so I just upgraded to the 9.1.2.0 Global stable again, and it looks like quick charge is working, but they've just removed the amperage reading from the lock screen, which sucks because that was such a clutch feature.

Quick charge doesn't work with the standard charger. I had the global dev and now the global stable of MIUI 9 and with both quick charge works perfectly fine, just not with the standard charger.

Why is this so inconsistent for everyone? Quick charge definitely works for me on the standard charger, although I don't use it. I'm on the latest 9.1.2 global stable.
As I said before, quick charge DOES work on 9.1.2 global stable, but without an app like ampere you'll never know it's actually working. We need to be able to see the actual charging current, and not some notification that says that it's quick charging.
Global Stable 9.5.4.0 (Oreo), QC works, but only with 6V and 1,2A

which is better 9.2.7 nouget vs 9.5.11 Oreo

Hi Guys
Today is the last day of my pc
Then I can't own a pc
So I have to be my phone with official stock ROM
So for that
Which ROM is better
And stable
And can anyone tell the process of relocking boatloder
9.2.4 was a godly build. It does not have camera portrait mode 2x zoom issues.
That said, I just flashed 9.5.11.0, and I dont use bluetooth and tethering, so I find it a good build. I use regular charger (though I have Moto fast charger compatible with QC 2.0 devices) and charging is fine.
I have also un-installed bloatware from 9.5.11, and I am getting SOT of 9hours with 2.5 days of charge period.

Yes
I'm still on 9.2.7.0 until Mi fix the issues with Oreo build. I usually get 7-8hrs of sot which is great as per my usage.
Why would you want to relock bootloader? Just flash MIUI rom.
9.2.4 is Better than Other Update.

Help please on my redmi note 8

Help please.. i updated my note 8 in the latest version 11.0.4 global version and
I recently experiencing slow charging.. from 6-8 hrs of charging until its full
But the worst is when i turn off my unit (totally) it wont charge
No battery bar or anything.. please help
Thanks for the feedback
Help me please.. is it software fault or hardware pls give me feedback thanks
Well i'm on 11.0.4 Global too from the day that it came out and i don't face anything similar, the charging speed has always been really fast as the first day of usage.
Plus, you're asking for a feedback but it isn't that simple to provide one since that you've provided no further details about the situation: by what i read at the moment, you've encountered this issue only after that you've updated the device to the latest build, but on the same build this doesn't happens by my side. Do you face other issues other than battery charging speed, or not?
Now, assuming that your charger is in an optimal condition and that the phone never felt to the floor that hard to compromise battery status, are you sure you didn't made ANYTHING else that could cause this? Facing a slow charging time on stock ROM and stock charger it's really weird and if you didn't touched anything else, i just can't find an answer to justify this behavior in stock ROM.
Hi Lads,
i recieved the same bug after updating to 11.0.4.0(PCOMIXM). The device is only online since december, so quite young
What did i done so far:
- Loaded a the Ampere App to check if the smartphone regonize the chargeingcable correctly. It does
- With the app i was able to see that the current while loading is between 100mA to max 450mA.
- I switched the charger to an Qualcom Quickdash Charger here the current jumps sometime up to 4400mA but only for seconds before falling down to 10mA
- I did a factory reset twice. First with replaying the googlebackup, second without googlebackup. With no difference. Still stucking on 100mA
Is there a possibilty to get back to a earlier Version of MiUi?
Next thing i'll try is to load the smartphone over the weekend to get more then 40% battery so that i can try to switch to a custom rom.

The capability to set to charge only till 80%. Have read in TG that this feature was dropped, due to the danger of getting the device bricked because of her. There's a post explaining why here in xda, made by arrow dev.
You can root your phone with Magisk and get the Magisk Module "Advanced Charging Controller".
Then, in a Terminal, you do "sudo acc 80" to make it stop charging @ 80%.

Sorry for being a bit late to the party, as cyanGalaxy quoted, you can use "ACCA", it requires Root, check out my post,

Are you able to customise the maximum charge level as with Evolution-X,
I like to charge my F3 between 35% and 65%,
this lasts me around 8 hrs and only generates 0.03 cycles,
this will hopefully keep my battery in tip top condition.

There is no built-in option for that but there are automated tasks you can set for that I guess. I also never have used Accu Battery app.

Hi,
I`ve been looking for many years for a rom with the "Smart Charge" feature, i have only found two for the F3, Evo-x and crDROID,
i used to use ACCA until Evo-X came along, i am always on the look out for roms with this feature to see how it compares.
I brought my F3, New 14 months ago and it still has 95% of the battery capacity left according to ACCU.
I try to minimise the battery cycles and phone temperature,
hopefully by doing this it will keep my Battery in Tip Top condition.

No this rom is called miuivn.
There's already some roms with it. But most of the maintainers aren't including it, because it can bring issues.
Anyway, I when I'm not in a rom with Smart charge, I always use a app called "battery charge limit". Super lightweight that allows to smart charge.

Hi,
Yes i also read about Charging Issues regarding Smart Charging, before i switched to Evo-X, i used ACCA and this was good, but i think it`s better to have this feature built in.
There were post regarding dead phones ect using the smart charge function,
yet i used ACCA for 10 months without any issues before switching to EVO.
If possible could you link to "Battery Charge Limit" as I'm not aware of this app,
cheers.

Hello buddy. Yeah I think we already have discussed that on other post. Supposedly it could bring serious issues to pmic controller.
But I used it around 3 years on my previous device (oneplus 3), without any issue. And now I've been using on poco, without any problems too. But well, I'm aware that someday it could turn bad.
I can't find on internet, but it's available on TG - https://t.me/RohailsHub/794.
If you prefer I can upload the apk.

Here
Some custom ROMs that have smart charging feature built-in include:
AOSiP ROM
Evolution X ROM
Paranoid Android ROM
Please note that the availability and functionality of these features may vary depending on your device and the version of the ROM you are using. It's recommended to check the ROM's official XDA thread or the Github repository for more information.

Hi,
Just a small update regarding "Smart Charging", I had to revert back to ACCA, as i use a QI Wireless receiver/adaptor to charge my phone most of the time and found that when QI charging my battery temperature was getting worryingly high,
at one point it reached 40.5 degrees, yet when using a standard charger my battery was fine.
I tried the app that you uploaded (Many thanks) but it looked very similar to ACCA except it had less functionality, i also found an (almost) identical Program on the play store.
So for now i have disabled the "SMART CHARGING" function in the Evo-X rom and reverted back to ACCA, as i am able to set the charge temperature.
I have set it to stop charging at 35 degrees and resume at 30 degrees,
I have also ordered a replacement QI Receiver to see if it resolves my issue.

I don't know why.
In case someone need fast charging on Chinese variant,
Check those kernel.
BTW, Sixteen is deprecated, and Ryzen no longer support fast charging on Chinese variant.

Finally, I switch back to QuickSilveR which from PE13+, Stable and battery friendly, even I have to charge my phone for 5 hours.
Maybe there are no other kernel, like Ryzen, which stable, battery friendly and support fast charging on Chinese variant.
