Evening everyone! Just wanted to say that I've read lots of complaints about fast charging as well as wireless charging not functioning correctly even after the update. I've had those problems since about the second week of ownership and I fixed it by replacing the OEM USB cable with one from Anker. Before it would sometimes be stuck at the same percentage for hours and the phone would be on fire, and now it fast charges every single time. Wireless charging also works consistently now even through a case. I've seen a lot of people have to deal with this problem, so I thought I would make a thread about it front and center.

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
For the last three months my G920F automatically connects and disconnects from the charger when it is connected to the wired charger. It happens quite oftenly when the battery is charging from 0 to 20 percent and when there are more apps opened i.e. the phone is drawing more current. This connection problem slows down after 20% though. I haven't noticed this on wireless charging. I ve bought a new cable and charger and the problem still persists. The phone will automatically disconnect and connect in a fraction of a second without moving any cable or phone.
So is it a damaged usb port or is it some kind problem with the charging IC? I am using orignal fast charger and cable and i have tried dozen other cables and chargers. Knox is tripped though.

Sounds like it could be the charging port if you have tried different chargers and cables, apart from that you can try flashing a new rom, just remember to back up.

Already tried that. Right now i am on stock marshmallow with space x kernel.
have the same issue since ~3 months. Its happening fitfully and i think about sending it into repair.
I was also using different chargers and cables but the issue still exists. So far the only work around is using wireless charging. I'm on Stock 6.0.1 btw

Please let me know exactly what do they replace as i have to do that myself here.
Hello friends
Nearly 1 month before, my phone started showing "Charging" when I connected the charger to my phone, instead of "Fast Charging". There was issue of connectivity with my laptop also. My phone was sometimes detected on my laptop, and sometimes not. I tried with another 18W charger, as well as with another 3Ampere Data Cable. But it always showed "Charging" only.
I went to Asus service center, where they also couldn't find what the problem was, and told me to deposit my phone with them. I instead of giving them my phone, went home and did a Factory Reset.
Afterwards the problem was gone, and it always showed "Fast Charging" when I connected my phone with charger.
Now since yesterday, again this issue is there. But this time it's little bit different. After connecting charger, phone shows "Charging" for about 1 minute, then starts showing "Fast Charging", but there is only 1 Plus in the battery icon in the status bar. And this thing does not happen every time. Sometimes, it shows "Charging" only, and not fast charging at all.
I have tried cleaning the Type-C port of phone as well as Data Cable, tried changing the cable used for charging the phone, tried changing the charger, but still no luck. I again did a factory reset, but this time it didn't solve my problem.
When I searched Fast Charging Problem Asus on google.com, it showed that there was similar problem in Asus Zenfone 5Z.
Has anyone facing this problem? Or if anyone knows how to solve this?
I don't want to get my 2 months old phone opened by service center at all.
See the battery icon in this screenshot..
It seems like a hardware problem. No such reports on Zentalk.

I noticed in your screenshot you have VoLTE.
That is not supposed to be possible according to Asus?

There's a "+" in the icon, so it's fast charging, just not as fast as "++". When fast charging isn't working, there is no "+" in the battery icon**.
In my case, I can only get the two "++" with the Asus original charger as all other chargers I have don't charge fast enough.
If you're having problems, you should do what they told you at the service centre.
(** It takes a few seconds for Quick Charge to enable, so you won't see the icon right away)
Yes, I am getting single plus icon in battery after about 30 seconds of connecting the charger. Previously it used to be double plus. Now since last 3-4 days, it is single plus, and charging is also quite slow. And yes it shows Fast Charging, but with single plus. When the problem started, there was just Charging, no Fast Charging. Now Fast Charging is there, but with reduced speed than before, and with single plus.
This is Indian version of Asus 6Z. Here it comes with Volte option.

Not really helpful but I'm having the EXACT same problem. Only in my case it stopped working completely, even after a factory reset.
This started on Android 9 and after the update to Android 10 it was fixed! Until I rebooted my phone and now the same problem occurs. Everything you tried, I tried too and nothing seems to work.
I hope you'll have better luck than me solving this issue, because for there only seems to be one option left and that's to send it to Asus repair centre.
I'm pretty bummed out especially because I have the 30 edition. It was naive of me to think they'd actually put extra care in this version of the ZenFone. I'm utterly disappointed and not looking forward to having this phone opened.
If you're using a 3rd party cable, try using one that came with your phone.
Before upgrading to Android 10, I was using a 3rd party cable and was getting fast charge. After the Android 10 update, however, fast charge stopped working. Once I swapped back to the cable that came with the phone, fast charge started working again.
So if you'reusing a 3rd party cable, trying using the one that came with your phone and see if fast charge starts working again.
I have tried various combinations like:
1. Default wire and default 18W charger
2. Default wire and other 18W charger
3. 3A Wire (1metre) and default 18W charger
4. 3A Wire and other 18W charger.
Tried everything, but sometimes just CHARGING, sometimes FAST CHARGING with Single Plus, and sometimes FAST CHARGING with Double plus.
From the above, it is clear that it is not at all hardware problem, because otherwise the phone wouldn't charge at all, or wouldn't show Fast Charging with some wire, and just Charging with another.
Everything depends on the current battery charge percentage.. @ 30% my phone charged at the speed of 3020MA unti 60% then dropped to 2500, then at 80% it was about 1100 MA and once around 90% i saw 650MA.. all readings using Ampere app on playstore..
Even I am facing the same problem with 6z I have the original charger but now it doesn't shows fast charge. And sometimes it takes more than 6 hours to charge the device from 15-20% to 100%. There no + or ++ sign on battery icon. Started happening after the latest update.
I have same Fast Charging issue with Asus 6z mobile. Is there any solution for this problem.
Not because of connector...
Guys, i had the same problem, won't connect to computer and won't fast charge, just one plus slow charge, i also thought it was just because there was dust in my charger or in my phone usb port, i cleaned as i could and tried, same experience, it worsened as time passed, as time passed i couldn't charge my phone anymore, charging cable connector was a little wiggly inside my charging port, so i had to adjust my cable somehow to just get charging, i also couldn't get an exact reason for the problem, so i went on with the burden, one day my phone just shut down when it was on 10 percentage battery, i was very afraid to take it to service center as my brother had bad experiences from various authorised and local service center, but one day my phone fell from hand and just won't turn on, it vibrates and it shows the off mode charging symbol for one second and goes, just nothing else, so i was confused with what was the problem whether it was with the sub board(charging port), battery or mother board. Anyways i had to take it to a service center, so atlast i took it service center and they had to send it to somewhere else to diagnose it, after two weeks i got it, they told me that my battery was short circuit(i don't know what that is) and is in bad condition, and the reason i couldn't charge was because of charging board or sub board problem, not because of wiggly port as i thought and battery was 1200 priced and sub board 350 something like that and 400 service charge, total was around 2000, and till now no problem, and they did a clean job as it seems it was never opened and the main thing, they gave me the replaced parts too and that was a surprise as i was very suspicious with these repair centre, i don't know about all asus service centers but the service in Kottayam service center in kerala was good from my experience.
Hey guys, something I've noticed recently with my X3 Pro is that whenever I have it connected to a charger that uses some kind of fast charging protocol, it'll charge for five seconds, disconnect and then repeat. It happens with all sorts of chargers and cables, all of which have worked fine in the past. Using standard USB-A to Type-C connections work fine but even the USB-A fast charge port on my power hub gives it this issue.
I've been looking online for solutions, tried air blasting the charging port, there doesn't seem to be any other kind of battery irregularities like a swollen shape or an increase in battery drain, now I'm worried that it might be the Type-C port itself. I'm running the latest version of Lineage OS but it doesn't seem like the OS has anything to do with it either as the charging problem persists when charging while powered down.
What do you guys think? I'm hoping it's not a hardware issue but I want a second opinion.
I have The same Problem.
Only The original charger works with fast charging. Haaven't found The issue on The Internet before your Post. Ist there a solution? Maybe this is Kernel related?
Poco x3 NFC nowhere near fast charging
So, here's my issue. Original cable N brick, charges almost nothing. Putting the brick N cable into my old not fast charging supported phone gives 1200 mA. Unbelievable N here almost nothing. Running MIUI 12.5.4

I tried 65w charger, phone didnt support fast charging, only original works well
