hello everyone. Yesterday a few drops of water were dropped in my type-c port of my poco x3. Then, when i tried to charge it, the charge was realy slow (no fast charging notification). After i clean it with paper, fast charge was working just fine. Today when i tried to charge it i had the same problem: No fast charging
Any tips how to fix it?
Sounds like you are lucky it still charges... Something could have shorted ... Perhaps turn it off for a while until it no longer has power running.. let it seat for a while and try again ...just guessing here .. might be it will re balance the voltage on the circuits
Probably residual moisture. As far as I know the port is completely sealed from the rest of the phone (not 100 percent sure) so no water should get into the device itself. So either wait or perhaps stick it in a jar with some silica gel packets. You also mentioned that you cleaned it with a paper towel, make sure there isn't a tiny chunk of it stuck in the port. Check whether the cable is clean too.
The most interesting thing is that is fast charges if i use another cable. So I can't understand what happend to the cable and some times it works and other not!

Plugged in Transformer last night to charge it up overnight when the battery hit 30%. I updated the firmware yesterday morning and everything was going swimmingly.
Woke it up this morning, and found it was at 9% battery remaining and had a low battery warning. I had a closer look and the battery icon shows no indication that it's charging when it's plugged in.
Right now I've plugged it into a bog-standard USB charger and turned it off, hoping it'll trickle charge (damn the lack of a charge LED!) and that it's a fault with the power adapter rather than the device itself.
Anyone else had this issue?
I had the same problem a few days ago, my charger was plugged in via a multi block and it would not charge.
I even went to the extreme of taking my device back to comet in the hope I could swap the charger out with their demo unit.
Man behind counter plugs my charger into some sort electrical surge protected socket and it starts charging straight away leaving me looking like a right tool standing their. (and they tried to sell me 3 years extended cover)
Brought it home and plugged it into the very socket where it wasn't working and what do you know? It starts working!
Not sure what the issue was but it now works again.
Ok well that's good to know!
On trickle-charge it's now gone up by 2% since I posted.
Looks like the power adapter has its own faults...
Oh, and what do you know... plugged wall charger back in (it's been unplugged for 20mins) and now it's all happy and charging again.
Hooray.
yeah maybe that 20 minute trip to comet fixed mine too..
the USB mains adapter plug has a fatal flaw - the middle part of the usb connection isn't as sturdy as it sould be so it is easy to plug a USB port in the wrong way around and it looks and feels plugged in correctly as the middle part just moves out of the way.
If it isn't charing always check to make sure the USB connection is in the right way around in the plug.
I am bummed about this proprietary power connector; and apparently proprietary USB cable with extra pins (negating the use of USB extension cables). I wish the TF had a standard round power adapter similar to the Acer A500.
Thank God, i thought i was the only one. Had exactly this problem with mine when it arrived a couple of days ago, i am lucky enough to have lots of USB chargers around so i tried and tested various combinations and tried to charge other devices with the asus charger.
The problem lies as far as i can see, entirely with the charger unit. The charger comes in two parts, one is the usb dock and the other the relevant country plug. The way the plug fits onto the face of the charger is the important part. There is a central 'locating pin' made from plastic and two contacts that slot into the charger carrying the live and negative. The construction of this part is very, very poor. The tolerances are not a match for the quality of the plastic, the T shaped plastic locater does not actually locate the bottom pins properly and needs a great deal of force to lock in placce, and here is the best part, it doesnt like STAYING locked. As the plastic is weak, and we are looking at just a couple of mm here, it will snap, that will stop there being a clean contact and no charge. As a remedy, i have secured the face plate to the charger very tightly with a high tech rubber band
I agree, the use of specific power connectors in this day and age is just as dumb a decision as any manufacturer can make, and the rate it recharges at from a USB to PC connection can only be described as comical, a full recharge in 26 hours . Aside from all that its nigh on perfect, but i can see power related alternatives being VERY popular until Asus catches up with the rest of the electronics industry.
havent even had mine an hour and i havent done the update because its not at 50% and it will not charg at all. when i first tried to start it i thought it was doa because it would not turn on. guess ill take you guys advice and leave it unplugged for a while. i hate the charging cable is so small too that definately sucks.
Hmmm... if only a few other people created topics about not charging...
Alright, so here is a fun issue to deal with. My notepro has always been a little slow to charge, but most of them are. However, its gotten very bad.
I have had issues with screen flicker and a little heat issues and some other small things off an on. So, fed up with it, a few days ago I rooted the tablet. It worked fine. Then I tried to install a new kernel and rom that was getting good reviews. However, when i did this, I couldnt get past the boot screen. Several reinstalls of stock and customer kernels later, my tablet started flashing and eventually died. When it was plugged in, it would show the battery icon with a circle in the middle but then die. Several tries to fix only seemed to solidify the tablet's fate.
However, yesterday I gave it another shot. I assumes the tablet had heated up and made the solder loose, so after a while it was solid again. It started charging, and after reinstalling stock rooted rom and stock kernel repeatedly, it was working again. I then installed the rom and kernel I was trying to before (I had to have a custome kernel to be able to control voltage for the screen flickering issue).
Now it is actually working. All functions are working, and oddly enough I am not seeing any screen flickering.
Only one real problem remains. Battery charging. The battery is charging so slowly that when the tablet is turned on, it doesnt charge at all, it creates a stalemate between charging and draining. It also drains pretty quick. The power drops about 5% in about 5-10 minutes of full screen brightness use (I was testing it this way to try and see if it would flicker again.
Its been charging for about an hour now, and only gone up 5%.
I have tried a couple cords and different bricks, but to no avail.
There are some thoughts, I am wondering if the tablet is only drawing power as if charging from usb, so only around 0.5a instead of 2.4a or so . I am also wondering if there is still a hardware issue.
I do not think it is the rom or the kernel, as this issue was happening as well after I got the tablet working again on stock but before I tried isntalling the rom/kernel again.
Any suggestions? I would be very appreciative.
I had simular problem with very slow charging, reboots and bluescreen. I opend my note to check battery plugg for broken soldering, but I found no problem with it. But to check turely i unplugged battery from main bord and replugged it again. After that I had no problem at all, now its charging normal, no reboots.. stil working perfect after averyday use for about 8 mounts......
If you are using usb cord not usb3 cord it will charge very little when using tablet . Mine will charge when off and below 25% to full in 7 or 8 hrs overnight.

Could be a bad charging port dock/flex cable. These are actually pretty easy to replace and can be found on Amazon. I had to replace one on mine. Try searching for a usb charging port dock flex cable for samsung galaxy note pro. That will cause the issues you are seeing. However the screen flickering sounds like a voltage issue caused by a cracked solder pin from the battery connection to the board. Which is very common on these and hard to see without an electronics magnafication glass. You could try taking the back off and pressing the battery connection firmly while plugging in your tablet and powering it one to see what happens. Either way sounds like a hardware issue.

Ok Guys, had the same problem with my 12.2 samsung tab pro, changed usb chargers, cables etc.
Found that the connector on the tablet itself (female) did not made good contack with the male usb.
So i simply , very careful, with a pair o pliers closed both tips on the usb conector, so the cable enters more tight. And voila, the usb amp meter i had showed a rate of charge from .33 amp , jumped to 1.73 witch is more than enough to charge and use tablet at the same time.
You need to do this at the end of the cable that plugs on the tablet, that is kind of double, maybe a e.0 usb or something like that. Make sure to close both tips. You want a tight connection
My pixel 2 XL stopped charging at all of the sudden and only accepts slow charging and with a "Chinese" cable. The original cable doesn't work. No the cable ain't broken or the charger. My girlfriend has a pixel 3 and she uses my charger and cable and works on hers. We used also her charger and cable ( from pixel 3s ) and on her pixel 3 everything works comes to mine it doesn't even recognize to start charging.
Yes I'm using the original one.. I wrote it all but I don't know why XDA deleted some stuff.
Anyway yeah always used the original one and always been using. Never used another cable or charger actually.
It just happened put of nowhere, morning was fine when I went to bed couldn't charge it.
The only way I'm able to charge my phone now is with those lame cables of 1£ and it charges super slow. 5h for 80%. But that's literally the only way.
I've done factory reset, hard and soft resets, battery calibration, cleaned the port with toothpicks... Nothing seems to work.
It's a weird problem because the original cables don't work just the non original ones , which charge super super slow, but I'm also sure the cable and the chargers don't have any problem because I live with my girlfriend and she always uses them ( the one who came with my phone and the one who came with hers , she has a pixel 3 ) and no problems with her. Just with me.
Maybe my battery is faulty ?
Try some rubbing alcohol and a toothbrush. Mine kept connecting and disconnecting repeatedly while charging. Here, I had a nice peice of lint in the port. Just an idea. Hope you get it figured out ?
I had something like this happen a while ago and the problem for me also turned out to be lint in the charging port. It actually looked totally clean, but when I stuck something in there to clean it out I was surprised that there was lint.
Don't stick anything metal in the charging port though, because it could short out the connections. I just cut out a thin piece of plastic from a plastic cup and used it to scrap around. A piece with a nice point on it is good. Try to pick out any lint that's at the bottom of the charging port that may be preventing the cable from inserting all the way.
Good luck. Hope that helps.
I've always liked the idea of being able to drop my phone on the desk or the side of the bed and let it slowly recharge without having to plug and unplug a cable. I also hate those bulky and ugly wireless chargers adapters that you connect to the charging port and slip them behind the case, since the adapter takes up the only charging port on the phone, and if you want to charge wired you have to unplug the thing before plugging the charging cable.
So, I bought one of those adapters, and fit it inside the phone, and it works great, and the phone doesn't get even a tiny bit warm during the charging period. I bought all the things on AliExpress, but you can find stuff everywhere online. Here's the links for all the materials and a video tutorial that I made:

Here's a soldering iron if you don't have one
A new back glass if you want to change it or accidentally break it

Remember that I did NOT do this project to turn it into a tutorial for other people, I just made it and then thought about sharing it, so only do this if you really, really know what you're doing, cause you might break something and I can't be responsible for that. I did this without even knowing if it was going to work or not, and it worked.
If you have any questions just ask, I'll try to help if you want to try this project for yourself.
Using vbus for chaging is clever, but is it triggering the overcharge protection? I mean does it stop charging after phone reaches %100? I will do it to my xiaomi mi 9 se, found that vbus and ground pins next to each other so it must be an easy install but i have doubts about overcharging the battery. Do you think is it going to be a problem? How is your device doing when it reaches %100?
I need some opinions on what part to repair on my Poco X3 NFC. My story is the following:
One day, precisely 2 years and 2 months after purchase (so just outside of any waranty, grrrrrr...), my mobile stopped charging the battery with a normal 1 Amp USB charger. Only a fast charger with USB power delivery still worked. 5 charging cycles later the phone did no longer charge at all, it ran out of battery and couldn't be turned on again.
I changed the charging port PCB, which is quite cheap and for a few days things were normal again. Then the same thing happened: Only a fast charger with USB power delivery still worked. 5 charging cycles later the phone did no longer charge at all.
Now my phone is dead again. Since changing the charging port PCB with the IC was not the problem, what do you suggest to do next?
Had the same problem.
Neither new charging port nor a new batterie helped.
The problem was die Mainboard cable. It only costs a few euros/dollars and is very simple to change.
I don't understand how a cable which doesn't move can break but the problem was definitely the cable.

Do you happen to have a good explanation why this happened to me twice? What are the odds of "first normal charging breaks, then fast charging breaks a few days later"? And to continue speculating: do you think I need a new charging port PCB this time as well?
It looks like my charging problems are solved by using a new charging port PCB and cable. At least for now the phone is still charging. However, I seem to have problems with 4G reception after the change. Does anyone have similar problems? No 4G after charging port PCB change?
I had the same issue with not being able to charge. I also couldn't use the aux port anymore. I replaced the port dock, but happened to break the main flex cable so I also replaced that. So it could've been either.
My 4G is working fine. Maybe you messed up the antenna?
