Mi 9 with Xiaomi 20W wireless charger, 120+ minutes to charge from 0 to 100%, defect?

I bought these together and today I tried the charging time by depleting the battery and do a full charge with the 20W wireless charger, the charging time is 120 something minutes, which is far from the official number of about 90 minutes, or 100 minutes from some reviewer.
I used the power adapter that came with the wireless charger, which has 27W, and plugged into 6 outlets power strip (totally 3 are in use). The phone is a Chinese version with Chinese ROM, 6GB+128GB. The phone was drained and turn on after charging start, and no explicit apps were launched, other than the system one.
I don't know if this is the charger problem or the phone battery, I wrote to Xiaomi but have not heard back.

Could be a subpar cable, do you get good speeds plugging directly into the charger with it?
If you have a case or ring grip or anything inbetween your phone and the pad that might be impacting speeds
Also placement is really important, you wanna center the ring on the screen on the pad as closely as possible
Probably not an issue as you got the charger with the pad but a thread in "XIAOMI MI 9 ACCESSORIES" I can't link to describes how there are fake chargers out there too

Mi 9t pro screen broken

Hi all, i have a mi 9t pro with broken screen. Before to order replacement i want to now if it works: when i connect it to a powerbank it seems to charge but i have no idea if the phone works. Is there a way to see if the phone works before to replace the screen?

Let the battery die. Then plug in a charger, press the power button and see if it vibrates. If yes then your motherboard is good.

Black shark 2 global

I have a 6 Gb / 128 Gb Black Shark 2 Global Model: SKW-HO gave me problems with the charging center after a power drop, when I connected the original charger the charging port and the usb cable was heating up, try to fix the problem by buying and installing a new Charging Flex. Here started the worst when I made the change the cell phone turned on but the starter was very slow something abnormal then the system gave me a message of humidity in the charging connector, from that moment my cell phone went off and now no longer turns on or with the Flex original loading.

Samsung galaxy S20 FE not charging

A few days ago my galaxy s20FE stopped charging while plugged in. Tried multiple cables, different plugs. Nothing worked. Even went a bought a brand new cable and plug just to be sure. Decided it was probably the charging board. Bought a new one, swapped it out. Still won't charge. It will charge on a wireless dock but thats it. What else could be the issue if I replaced the charging board and it still isn't working?

Battery or mobo failure be my guess.
The replacement C port pcb was the same PN right? If not that maybe the issue.
It's possible the replacement was defective.

The part numbers are the same. I wouldn't think it would be the mobo, it's still on and functioning. And it does charge with the wireless, could that still be a battery issue if it charges with one and not the other? The battery only plugs into one spot on the mobo

If you power off the phone will it cable charge?
Make sure the cable, brick and wall outlet voltage are good. Try another outlet...
Use a Samsung brick.
The power controller is on the mobo or at least part of it is. Try replacing the battery, if that fails to fix it replace the C port pcb, again.
Also:
Clear system cache
Do a hard reboot, disconnect battery then reconnect if you haven't already.
Try toggling fast charging on/off 3 times.
Inspect pin connectors on all associated ribbon cables for damage.

Samsung Galaxy S20 FE charger problem: If your Samsung Galaxy S20 FE does not charge at all, it may be related to a charger problem. In reality, the cable/adapter combination may no longer work.
Check the condition of the USB socket on your Samsung Galaxy S20 FE: These sockets are fragile and can, as time goes by, and the manipulations become twisted or engorged with dust.
Samsung Galaxy S20 FE does not or almost does not charge even though it is charging: In this case, it is undoubtedly the use of your android smartphone that prevents it from recharging properly. In reality, if WiFi is on, whether you are watching video content or otherwise, you may block the charging process.
Battery concerns: It often happens due to age that a battery loses its storage capacity. If you have access to the battery, check its condition, otherwise try to compare the autonomy of your Samsung Galaxy S20 FE compared to the one it had when it was new.

I had the same issue with a other Samsung M31s. Tried everything you did. Ultimately came to know 1st time it was IC internal damage and second time it was wiring on mother board.

Question Solved! Mi 11 Ultra charging

Hello, i just bought a Chinese Mi 11 Ultra. It came with a 67W US charger + US to EU adapter (i live in EU). When i'm charging the phone it says "turbo charging", not "67W Max". I tried a 33W xiaomi turbo charger and it charges the phone at the same rate (at least that's what it says in the battery section).
Can anyone help me with that please ?

Hi infamas,
did you try another USB C cable ( it must be the orange one...)
--> Usb-cable
Good night

yes i tried two different 6A orange cables, same result

Hello, I have about 3 weeks since I received my Chinese cell phone with global ROM. It included a "67W" charger as a gift but the truth is, even though it comes with the original cable, I think it is not the corresponding charger. My wife's is also 30W and I feel that it gives more Loading capacity.
I bought a 66W car adapter, and I haven't had a chance to use it for more than 10 minutes, and I think it's the only one that gives 100% of what it offers. I don't know if a warning will appear that it is the maximum power
In the screenshots, guess which one is mine?

SOLVED! The cable was the problem. It turned out to be non original or a 6A cable for Huawei/Honor.
Now when i connect with the original 6A Xiaomi cable i get "67W MAX" charging appear on my screen and it is 2-3 times faster than turbo charging.
