Hey,
A few days ago I got an update to MIUI10 Beta for my RN3 (snapdragon). After uploading the update, my phone started to charge with a maximum current of 0.4A (screen turned on, 0.6A when turned off). I decided to unlock the phone and flash LineageOS 14.1, unfortunately I still have the same problem.
Searching for topics related to this problem I found a "solution": https://forum.xda-developers.com/redmi-note-3/how-to/fix-slow-charging-t3662571
I tried - it does not work.
I tried also wipe cache/dalvik - it does not work too.
I tested on 3 chargers:
1. Apple 2.1A Out
2. Apple 1.5A Out
3. no-name 1.0A Out
-----
I used 6 cables for the test - on each of them the same.
Summary:
Before the upgrade to MIUI 10 - loading about 3h 0-100%,
After upgrade to MIUI 10 - charging about 8h 0-100%
After changing to LineageOS - charging about 8h 0-100%
Additional info:
I have this RN3 for 3 years. Maybe it's battery problem? After 3 years battery capacity has dropped from 4k to 3.2k-3.3k.
I would ask for help in solving this problem.

Thanks for reply! I will do this tomorrow.
New anomaly -> RN3 is turning off at 15% or less.

Okay, I flashed miui and... nothing. RN3 is still charging 0.41A.
Second anomaly - on Xiaomi Powerbank 10k, RN3 is charging 0.72A
Third anomaly - 11h charging from 18% to 100%.
Fourth anomaly - RN3 is charging only to 75%. I have plug off and plug on charging to continue charging more than 75%.
-------
Any suggestions? Maybe should I change the battery? Maybe this module with usb port?

Take ear bud and apply some spirit alcohol on itand clean ur charging port of ur phone. May be sometimes dirt or carbon or rust affects the current. Spirit alcohol or isopropanol is volatile and helps in cleaning the charging port.
If u dont have spirit alcohol then buy a small bottle from pharmacy.
I have the same problem in miui 9 then I installed lineage os but issue remains . then I tried random kernal problem solved

Okay, I changed ROM to ViperOS and it was still 0.41A, so I decided to flash NitrogenOS. A little bit better. Now it's charging on 0.80A on 13% battery.
Maybe some more suggestions?
Thank you so much for replies. I really appreciate your help!
@edit
Now charging from 13%-100% take "only" 5 hours. It's bad result but it could be worse (11h on 0.4A).
@edit2
Also fifth anomaly - RN3 is randomly turning off after show a 0% battery notification. (On LineageOS 14.1).
Maybe this is problem with overheating battery. When battery is too hot system limits charging current. Did you tried measure real charging currend using eg. multimeter?

Hello there,
I have this small buddy:
https://ae01.alicdn.com/kf/HTB10vcSQVXXXXbRXXXXq6xXFXXXk.jpg
and all values which I wrote here were measured by this.
I will try thermal libs on NitrogenOS.
UPDATE
I tried thermal libs - nothing changed.
I have a notification on lock screen: "Slow charging (5hr to 100%) 715mA - 3.9V - 34*C"
Even I am facing this exact same issue after MIUI 10 update and it persists even when I changed the ROM to DotOs. The extra bit of information I can add is, the only reason for me to flash custom ROM was to get the charging done faster and immediately after flashing the ROM it did show "Charging Rapidly at 2022mA" in the lockscreen(a custom ROM feature) but only for 3 times and after that it keeps showing 0.4mA as the charge current. In my opinion we need to flash an older firmware of MIUI as MIUI might have purposefully done this in its latest update to make charging safe for old batteries (mine too is 3 years old!) and temperatures where climbing up to 45°C when it was fast charging. Any help would be highly appreciated with a thank you.

Why don't you just flash a custom kernel, instead of ROMS
I tried plenty of ROMS - POSP (PIE), Bootleggers (PIE), CM14 (Nougat), LineageOS (Nougat), NitrogenOS (Nougat).
I tried few kernels - Radon (for PIE and Nougat), Shadow (Nougat), AGNi (Nougat) - For all kernels I checked few options - new thermal lib, old thermal lib, QC 2400mA, default options and other variations.
I corrupted my persist.img (all of my sensors were dead) due to flash too many of roms/kernels/stuff - had to flash new through fastboot
On all of roms/kernels/stuff I had 0.41A - Only on Bottleggers I had 0.6A and NitrogenOS 0.8A max.

Can you tell me, which kernel would improve my charging?
update (18.03.19 3:23PM):
I changed stock kernel (ROM: LineageOS<Nougat> - 0.41A) to Badjingan pie. Actually I did it completely by accident. I thought that this is a nougat kernel. Aaaaand... it increase charging to 0.8A. Checked on USB 3.0 in laptop, Lenovo QC charger and no-name charger 2A.
Another update (18.03.19 5:27PM):
I changed the Badjingan kernel to Radon 6.3 for Nougat. Again 0.41A and nothing changed if I choosed new or old thermal but I found an option in Radom Kernel Control which is "Quick charge by USB" and when enabled, the current is changing from 0.41A to 0.80A and that's it.
Update (26.03.2019 12:20PM)
I flashed stock Miui 10.2 Global (Android 6.0.1) and charging issue still remains.
Also tried to flash thermal libs - still nothing.
I will order new battery and usb charging module.
Hello there again.
After this tries above I ordered a USB charging module in my RN3. So few minutes ago I mount it up to phone and check if charging is better. Aaand... Nothing Still 0.41A. Checked on POSP 9.0 (stock kernel). Tomorrow I'll try to change to other kernel (maybe Viper N).
Few days before, I changed ROM to Miui 10.2 Global. The charging current was aprrox 0.06A-0.2A.
The same problem
I have the same problem. As you have described, it has also happened to me after upgrading to the latest version. I have Already tried with different chargers and cables but nothing. I don't think it's a coincidence, I've already been through all the Roms that are here but I have not solved anything and the issue begins to be tired.
Thanks for reply. We will figure something out
Okay so there is an update:
I've changed (again) to MIUI 10 Beta ROM -> 0.41A
I've installed AGNI Kernel with old thermal libraries option (during installation) and... 0.66A from laptop USB 3.0 on 50% battery. The same current on MI Powerbank 20k.
The next and the last thing before throwing RN3 through window is replace the battery.
Stay tuned
I used to charge it while watching videos or playing, but today that is no longer possible. Sometimes, for example, being at 20% battery power and connecting it while I do those activities, it stays at 20% all the time or even low instead of charging.
I don't know in your case or if you've already tried it, but I've seen that the problem is only charging the phone when it's on. If I charge it when it is turned off, the charging time is normal. About 2 hours.
Clean flashed Havoc OS 9.0 Rom and Nano gapps + Thunder Kernal
Everything seems to be working fine.
Only 1 big issue is that The phone is super slow charging now,
Using a blitzwolf 2.4A/QC3.0 charger and the cable can charge at 1A or more on my Oneplus One but on the Redmi Note 3 SE (kate) seems to charge only around 0.2A
I use to be able to Charge at 2A under stock MIUI ROM
but since flashing this rom barley gets past 0.2A
Anyone know why?

Hahha.....lol..
Get ready to go service center. Never use quick charge 2 or 3 on rn3. It will burn ur charging board.
Always use stock charger 5v 2A.
it worked fine for 3yrs, only when I changed the Rom did i encounter the slow charge issue

Dont use quick charger on custom roms.
Because of SD 820 And unoptimized zui
Our zuk z2 heats alot.
Share your methods here
For the best heating solution ?
Non treble rom and battery to save setting?
Use latest Aosip pie rom works great with minimum heating. Can be used as daily driver ( I am not a gamer) it gives SOT if 5 hrs with stock battery of 2 yr old device.
Hello I'm trying to find a rom with a good battery life, so far I tried 3 roms, xiaomi eu (the best at the moment in battery), the redmi note 7 port rom and last CarbonOs, what rom do you reccomend?
I suggest lineageos with andoird 10, and gapps is pico.
Maybe u can try arrowos
Hard to say, but i tried LOS 17.1 April release and I found terrible power consumption because of pernament awake state. I dirty upgraded to May release and all is fixed and during 8h of night in baterry saver mode it lost 0% of battery. It looks great. I never seen similar result on my pad 4.
I've updated my Redmi Note 9s with the new MIUI update 11.0.10. I've noticed when I charged my phone, that it inly has the single lightning icon beside the battery which means it is not fast charging. I've used different fast charging capable cables and chargers (even the original cable and power brick) but it doesn't work.

I think it is still working, they just updated the fast charging icon two lightning bolts above eachother instead of next to eachother.

No worries, i didnt either at first, I thought something wasnt quite the same.But seems they snuck in the change in 11.0.10. It was only when I seen that miui12 post that I realised they'd implemented in v11 too.

As the title said, I recently tried pixel plus experience rom and I suffered from two main issues, the Slow charging and missing camera features, can you recommend me a rom that doesnt have those two issues?
The only ROM, AFAIK, that may have a somewhat working MIUI camera is crdroid with the testing version of ANX for A12, but I haven't used it. About battery charging, have you actually measured how long it takes to charge the battery with different ROMs? I personally don't care about charging speed that much, you will be limited more by temperature than anything else.
in every rom i tried fast charging works fine... i'm using the original 33W charger

I switched now to crDroid and surprisingly it supports turbo charging and charges fast as well! but no, no MIUI Camera.

CrDroid is the only ROM that supported fast charging for me.
Other option is to flash a module in magisk for fast charging if the rom dont support it. you can verify it after, using amper

I actually did, but crDroid is the best at it! it directly indicates turbo charge
