Problem with fast charging - Xiaomi Mi CC9 / Mi 9 Lite Questions & Answers

Hi guys , I am on 12.0.3 EU version and i have a problem with fast charging. Suddenly couple days ago my phone stopped fast charging. It would take like 3hours to charge with the same cable and charge brick. I did a reboot and it was ok , but every time i try to charge again i need to do a reboot to start fast charging. Is there any solution ? I know that factory reset might help but i want to try everything else before i do so. ( cable and brick is ok ) Thanks in advance

I am not expert but as experience I think your battery recharge cycle period near to finish or need more time . I replaced old charger 18W to 20 Watt charger .
now original Xiaomi charger 1.5 hours its working 100%
Try it .

people for real only use power chargers if you need to get a fast charged deviced. they degenerate your battery really fast!
if you want your battery to last more cycles let your phone charge with a max. current of 0,5 A. PC usb port is the best you can use...

[Q] So hard charge my samsung tabs battery

Hi All,
after reset to factory, my samsung tabs so hard to charge, until now just 5 % after reset, any suggestion for me to solve my issue? or this is normal?
BR
Jellf
Already 8 hours charged, but indicator shown battery just inserted 7%.
how can i do now ... any help please
Are you charging on PC USB or normal charger?
Sounds to me that he is "Trinkle Charging". DO NOT attempt to charge by plugging it into your computer. Use the charger that came with your tab. It will charge MUCH faster.
Sure you can charge it plugged into your computer.....if you want to wait a week or so. LOL!!!!
same problem
i did a factory reset too,
but my problem started alot later.
it gets stuck at 3%
and doesnt charge.
i dont trickle charge,
i charge from the wall
but it doesnt charge..
helpme!

Problem with Cyanogen 12.1, No offline charge

So i've recently flashed the last stable cyanogen rom 12.1 (first i've tried with TWRP but i got error so i did it with Odin) . I was using a modified stock rom before this.
After flashing with Odin i noticed that i couldn't charge my phone anymore with a generic wall charger (original charger works intermittenly, almost broken). This generic charger worked fine with the stock rom. Using the old original charger works but charges at very low speed. And then i realized that i cannot charge the phone offline, i've recently bought a new battery because i thought the older one was mal functioning but now with this problem i think i've already killed the new one.
So what should i do to fix the charge issue? Roll back to stock? Try KitKat maybe? Usb charging works but really slow charge too.
Thanks in advance for any help, tip you can give me about this issue. Happy new year to all.
Edit: another thing i've found is that the battery may be overheating, is this common with this rom? or is it part of the charge problem? the phone feels hotter in my hands while i'm using it.
I dont have any problems with overheating.
How long do you mean by 'long charging'? For me it's ~2,5h. The longer battery charges, the longer is its life.
I have also problems with offline charging, but it's not game breaking, you can charge battery in TWRP.

I mean is really slow, and my battery doesn't charge 100%, it gets to 92% no matter how much time i charge it. But that may be a problem with my new battery (i didn't charge it right the first time, because i couldn't charge it offline)
So is this offline charging problem common using this rom?

I bought the phone like 1 year ago
So I tried to clean the port
Change cables
Change power brick
Change power source
Still ..... The phone won't charge
However, if I plug the charger when the phone is turned off it will charge.
Then of course I turn back the phone to use it.
But when I unplug then replug the charger when the device is on, it won't charge again.
So Everytime I want to charge, i need to turn off the phone first

Try rebooting the phone several times leaving the charger attached.
That is free!:good:

Try maybe flashing a custom rom, or even flash a custom recovery and check if the phone charges while in recovery mode so you know if the problem is with hardware or software.
Just unplug battery overnight, usually sorts this sort of thing out, while the back is off disconnect the port cable from motherboard insure it's clean and reconnect
I replaced my battery and it really was not that hard at all. Mom had a
i have the same problem. I believe it is a software problem. hope for a update to fix it.

Naa, just leave the battery unplugged overnight, will take awhile to start charging again but should be fine
Yes, same here. The phone just stops charging and as well starts discharging rapidly with the charger connected.
I am on the PIXEL rom currently.
As I had tried the RR ROM and the look and feel for the phone wasn't quite to my liking.
The phone charges fine when it shut down. But refuses to charge with any PC/brick/cable.
Also, the phone heats up hard at the general fingerprint scanner & Camera area. When this happens.
I have no other choice to shut down the phone and charge it and then use it. Whats can i provide for any DEV to check the problem?
Is it a kernel fault? Software? Hardware?
Any help would be appreciated.
TIA

Hi, I get it back to charging after doing a hard reset by plugging the charger to the phone and at the same time press and remain power button, the phone shut down and when i re-start again it keep charging. Try that
I have Xiaomi Redmi Note 8 and my phone was shut down when i completely discharged the battery. I tried the charging with original cable and adaptor but didn't charged, only seen battery icon. For just trying, I charged with a powerbank and ITS WORK. Firstly the powerbank light is going off within 5-10 second, I tried a few times reconnect the charge cable and booting my phone then the powerbank light wasn't off and my phone started normally charging.

Super slow charging problem

Please help me get fast charging back. Like 3 months back, my phone suddenly stopped charging fast and since then its charging super slow. Like if I use it while charging it actually discharge. While switched off it takes 4+ hrs to fully charge.
I have replaced battery, usb assembly, charger, cable everything but to no avail. Now I think its a software issue. Maybe some kernel, firmware I screwed. I have tried Syberia, Xiaomi EU, Rev OS roms as well.
Ampere app never goes beyond 300 mah reading, whatever charge cable combination I try. Please throw if insights.
Thanks a lot

Fast charging issues

Hey guys! A few weeks ago I noticed that fast charging doesn't work with my usual power sources (Xiaomi Power Bank, Xiaomi QI Car Charger), even though it worked before that. I only get around 850 mAh with them. The only way it works if I use the original wall charger. I use the original and a Baseus cable. It is also slow with the phone turned off. Any ideas what causes this?
what rom

The fast charge brick is needed to power the basic functions of the charger. I suggest you get the 27W brick in order to get the 20w fast wireless charging

Xiaomi.eu ROM, I unlocked the bootloader a few weeks before this issue, but the problem also persists when the phone is turned off. Should I try to flash back the stock ROM with MI Flash?
My mi9 lite phone went slow charging too. Phone usually got a full charge after 2hrs but it went to 4hours to get a full charge after i connected my phone to transfer files to my laptop through a usb cable. What i did to get the 2hrs charging was reconnect my phone to the laptop using the same usb cable. At the phone a pop up appears with 3 choices...1st choice(forgot),2nd transfer files, 3rd transfer photos. I tapped the 1st choice and disconnected my phone. And i got my 2hrs full charging time back. Hope this will help.
I am on 12.0.2 and takes 2 hours to charge 90% mean that ~1.5 minute 1% charge
before flashing this ROM via EDL method took around ~1 hour with the original charger to charge from 20% to 90%
