Mi Max 2 charging very slow... how to solve it ?
Just change USB cable and use Xiaomi original charger
any more info on this? what do you consider "slow"? full charging time in my case with original xiaomi charger and cable averages 3.5 hours in my case (until charging amperage drops to zero, so this goes beyond the mere "100%" on display)
i also experience this bug. really slow charging. it takes me 9 hours to charge from 0% to 86%. im using the original charger and cable from the box. anyone know how to solve this?
we need more info in order to help you.
- which rom do you have installed?
- which kernel?
- whats the state of your phone during charging? do you leave the screen off or check every 5 minutes or use it permanently? got all sensors (BT, GPS, Wifi, Data, etc.) switched off and using flight mode?
- how new is the installed rom? did u just install it and first charge?
Agree! Without basic information about your phone, don't expect help at all.
same problem.. too slow to charge.. up for this
does anyone have an answer for this?
see above... provide more info on your specific use case.
im using miui10 beta and stock kernel.. the battery is great but so slow on charging.. it takes 6 to 7 hours.. but when im using powerbank and put into 2.1 a may charging time become 3hrs something.. what is the problem of this..
I have a same problem, I thought it is because of my Original Charger of Xioami, maybe the problem is the software.
This is my phone's MUI Version: MIUI Global 9.6 | Stable 9.6.3.0
Interestingly, I recently upgraded firmware to 9.6.3 and faced the same issue.
Fortunately I had a full backup from a few days earlier so was able to restore the firmware partition as a troubleshooting exercise.
Charging speed with 9.6.3 and screen off was logged at an average of 1723 mA.
After restoring the firmware partition from backup, charging was logged at 2935 mA.
Same charger and cable for both tests so unless there's something else at play that I don't understand, pretty sure it's a firmware issue.
Since I replaced the screen I am issuing the same problem. Charging super slowly about 15% in 2-3 hours and overheating.
I will replace the battery first
Hey all,
I have a comsol dual wireless charger (15W per side).
There is a green light that flashes when a device is charging on it.
I noticed that my partner's Google pixel 3 will stop charging when it gets to 100% (and the comsol goes solid green).
However my Mi 9, the comsol will constantly flash to indicate charging. Even hours after hitting 100%.
In the morning the Mi 9 is very warm, and the pixel is cold.
Has anyone experienced this before? Am I damaging my Mi 9?
Thanks
Dude stop using that thing and get the version especially made for the Mi 9
Of course you are reducing the life span of ur mi 9 battery that way.
Plus in first place you shouldn't leave it charging at night .. like why would u do that? You only need 1hr to fully charge it in the morning before leaving. (like 1:38 with original wireless charger)
I have a similar problem with aosp rom, we have a solution?
Dear all,
I have problem with my Xiaomi Mi 9t Pro, it stopped fast charging. My phone is on Miui 11, Android 10.
Some day i've noticed that i've got only 1 "thunder" icon during charging. Charging from 0% to 100% takes about 7 hours now.
What i've done so far:
- tested on charger which was included in the box - no fast charging
- tested on Xiaomi Power Bank with fast charging - no fast charging
- tested 4 diffrent cables - no fast charging
- tested on turned off phone - no fast charging
- i've downloaded last update package and install it once again - no fast charging
- i've tested charging speed on ampere - maximum is 800mah
I've found some topics on various forums but there was no solution for this problem.
Any ideas friends?
Worst case scenario it is damaged charging port. Try to clean it using thin piece of wire or needle, it's easy to clog it up so the plug doesn't go all the way into the port.
I would take the phone to a service center. Even without fast charging is not possible that it takes 7 hours to get a full charge. It seems that the charging port is defective.
Good luck.

What kernel do you use with miui? Stock or custom? Some kernels don't support charging via 5A cables. Use 3A instead. Also, clean your usb port with a toothpick and see if you can remove any dust from the pins.

Hi,
I've been using my Redmi K20 Pro since November and I encountered a problem where my phone won't charge. I tried my backup charger and usb-c cable but it still didn't work. Once I restarted the phone it began charging again. Based on my testing once I unplug the charger I need to restart again to see the lightning icon charging indicator. I also noticed that the charging speed is very slow unlike how it used to. I am using xiaomi eu and I updated to the latest version thru the update app but still having the same result. Has anyone encountered this or have an idea on how to fix it? I see lots of similar issues with xiaomi phones but of different model on google but I can't find anything useful.
Thank you

Sounds like there's and issue with charging port and daughter board, if you've done a reinstall. Does the same thing happen when charging from a laptop or pc?

Ah okay, that's really strange, I was thinking it might be the port but if it works fine on USB then maybe not, and you've tried a completely different plug and cable aswell?
Do you use any battery charge limit apps?
If you are like me flashaholic, then sometimes with dirty flashing rom gets messed. Try flashing stock (fastboot rom) miui to teset everything to stock and then see if it charges normally. If not there could be hardware issue
With regards to the replies above..
I've only flashed once to Xiaomi EU. I've also tried a different usb-c cable
I notice that when I plug my phone to my laptop, it keeps getting disconnected and reconnected for any small movements of the cable
Sometimes I get fast charging when I perform a restart so it starts to charge
I don't use any battery apps or any cleaner apps

Sounds like the charging port has an issue, the fact if it is connecting disconnecting from movement of cable points to it I reckon
Hello,
Have you solved your problem? I have the same insue and I can't solve it, the last option was to flash the last oficial global rom (fastboot methdo), but it didn't solve it ...
Thank you.

So, I have this issue on my another phone poco f1 what I did was clean the charging port with some stick and cotton. Basically its a charging port issue, you have to clean the port or take a service to clean port completely or change port this issue will be solved
Mi 9T (Global) have the same issue, i check with USB Tester...
every restart the charging system is reset.
Before restart: 9-10W
After restart: 16-17W
Same adapter & Same cable & same time
Some times the phone not charge at all
Restart solve this issue
When i connect the phone to computer it's not work
Restart the phone when his connected to the computer solve the issue
Xiaomi fix you hardware & software !!!!
Hello
I have the same issue with my two phones MI 9 T PRO, never used USB C before, even 3.5mm jack, i have the error message on the notification and i cannot remove it: "Can't play audio through adapter. Use digital earphones or earphones with 3.5mm plug". when i plug my charger into my phone the fast charge is displayed but it won't charge, The only way to charge my phone is to reboot it and it's charge like there is no problem! but the error message is still on notification but charge with fast charge! I bought my phones march 2020, and the issue appeared since sept - oct. I have the latest update MIUI 12.0.3.
I facing same problem on my mi9tpro with global miui12 what's going on guys how to fix the problem?
Hey guys, I think I have the answer!
Its all about the MIUI optimization, you just have to go into developer options, search for MIUI optimization, turn it off, restart, turn it on and restart again. Everything should go well after this! I hope all of you end with this headache!

Hello team!
I was facing the same problem on a Redmi 3S Pro, and decided to come by and let u guys know my handling of this.
My phone has quiet some years of usage right now and its a bit beaten, but still runs great.
Out of nowhere it decided to not charge anymore, and I noticed it would charge with device off or after a plugged restart.
It decided to work again after i entered fast boot (unplugged) and exited fastboot back into system then plugging.
Not entirely sure this fixed it, but looks like it.
Some notes:
I was trying a couple things like trying to enter safe mode and combinations of plugged/unplugged restarts
I did not factory reset
I did not let it end the fastboot loading (force rebooted somewhere in the middle of loading fastboot)
To fastboot, power off the device, then press power button and down volume
If u dont know what u doing, DO NOT go sticking metals into your usb port to clean it, cause if it charges when off, this is NOT dirt problem. Be advised..
I was able to reproduce the issue (sadly) after playing with normal reboot/fastboot then reboot , but then i tried reproducing the fix:
Unplug and turn off device
Turn on to fastboot (down volume + power)
Now, first time, after entered fastboot screen, i rebooted and it did not work, then i tried again but i had to let it run a bit longer on fastboot screen then reboot for it to work
I know the fastboot performs some system checks while loading, but i don't have much time to keep digging this, maybe another day i'll come back with more info.
I'm guessing its system issue, not hardware (at least in my case).
But now, charging is working even after normal reboots for me, so i think i'm onto something =]
Hope this can be useful to someone.
Happy hacking!
Cheers
Hello everyone , I had the same issue and fixed it .
My solution was to change the usb-c port (daughter board). everything works as its supposed now.
I looked everywhere for software issues , flashed many different roms to no avail.
There was only one rom that tipped me that there was a problem on usb c port though, ita pixel experience rom, it showed a persistent notification that there was something plugged in the usbc when there was nothing there.
once I replaced my port (cost only 14$ for original with fast charging IC) ,and upon inspection of my replaced board under microscope , the last pin on the left in the usb C port was bent in a way that was impossible to see with a naked eye, now I bought a usb c port and soldered it back to my original daughter board and I keep it as spare one.
Hope this will save you your battery and your time.
(if you keep using like this and have to restart everytime for a charge , it will eventually fail , better replace it when you have time , than your phone going off when you most need it)
