n short, I have an HTC U11. I have gotten water in the connector a few times which caused the phone to turn off or fingerprint scanner to stop working but then after a few hours would be fine again. Several months later I noticed it took a very long time to charge. I downloaded an app that basically diagnoses the amperage and it said that it was fine, but I honestly could not tell you if it was true or not. Fast forward a couple of weeks, I drop my phone and the screen cracks. I replaced the screen at home and today the battery still charged slow.
So here is what I did
- Used rubbing alcohol to clean out the charge port and found black gunk inside. I thought it was dry and I plugged the charger in and I received a warning and buzzing stating it was wet or had debris inside. I removed the charger.
- An hour later I plugged it into my car, same problem as a few weeks ago with slow charge, but it was working. I unplugged my phone to go to class. After class I plugged in the USB , noticed slow charge, then pulled the USB C out and back in, I received the warning again and now it wouldn't charge. No red light, no charge now
- Removed the back cover. I noticed the battery has no heat after 5 minutes of being plugged in but the charging port is absolutely on fire. It even smells like melted plastic. I removed all the black gunk, same problem.
Summary of fault
- Gradual slow charge.
- Warning that debris or water damage is in the connector
- Black gunk found inside the connector (but not on the charge port board)
- Charging port board gets hot to touch
- Battery stays cool
The big question:
Charging port or battery?

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...
Hey guys
I've a really big problem with my A510. Last week I charged my tab as usual. After a while I've checked my mails and felt that the tab was unusually hot, definitely hotter than on normal charges. I therefore disconnected the charger and the USB connector was terribly hot. I've checked the charger and noticed that the cablewas broken. I took a closer look and saw, that both wires have been ripped open and probably connected each other. I think it has created a short circuit, caused the USB connector to even melt in the inside.
Funny thing is, that it was possible to charge the tablet to around 60% and I've used it to order a new charger which arrived today, the battery is completely empty and the tablet can't be turned on. So I've connected the new (original Acer charger, no cheap copy). The orange LED on the power button appeared as usual, but I didn't turned it on as I wanted it to charge a bit before trying to booting it up. After an hour or so I checked the tablet and it was again unusually hot and the orange LED turned off. I've disconnected the charger and tried to power the tablet up, put nothing happened. Also pushing the reset button will not boot up the device. I've connected the charger again and the orange LED also appeared again, but after around 10 seconds it turned off again and the tablet got already hot within 30 seconds (around the area where Iconia Tab is written on the front side).
Does anyone have any ideas what could have happened? I'm thinking that the battery might have been damaged by the short circuit, but on the other hand I was able to use the tablet a day or so before the battery went down to 0% which would mean the battery might be ok.
I'm clueless right now and would be very happy for every idea.
Thanks!
Yesterday I've opened my tablet to check for any thing obvious. After opening the device I could already smell burned electronics. I further disassembled the device and found one IC on the mainboard which had some brownish powder on it, the IC type was no more readable. After plugging in the power charger this IC went extremely hot, so I assume that it burned while the broken charger was charging up the battery. I checked the internet for a replacement mainboard and found some on Alibaba. As the price is too high for me and I can't define if there are any more broken parts I decided to buy me a new tablet. As I was very satisfied with the product from Acer I've stayed with them and bought myself a Iconia Tab 10 FHD A3-A20.
I've had it for quite a long time. The black marks/residue on the full USB get off easily when wiped. It smells of burnt electronics and so does the female USB port on the charger. Neither the charger nor the cable (both OEM) get hot when charging (just the usual when charging at 1.8ish amp until the battery hits 80%, but that's only the charger not the cable). Neither are damaged physically. I received the OPO about 4 months ago. The reason I made is thread is because the phone stays warm even after it hits 100% (when I plug the phone off after an overnight charging period) and this started happening after upgrading to the 12.1 nightlies, so that might be a totally different issue. Should I get a new charger and/or cable?
I am very concerned right now as every time I plug my Google Pixel XL 2 it does charge but it also turns off. I do believe that the reason for this is that I had my phone on my desk as well as an ice lolly (yes i know) and as i was busy on the computer I forgot about the ice lolly and it therefore melted, it so happened the phone was drenched in the liquid. As soon as I realised this I quickly rinsed the phone off as I was aware the phone is ip67 so it can handle water. I did not think too much about it and went about my day and left it charging (or so I thought). About 30 minutes ago from writing this i noticed the charger was not connecting properly and I became worried. Next the phone did start charging but after 10 second or so it switched off and went into a charging only mode so I turned it on again but it would only power up if I removed the charger. I have tried two chargers the one it came with and one I already had. I am currently very concerned as it cost me an a lot of money and I cant help but feel it may be broken due to the ice lolly melting any ideas would be appreciated.
I have had similar problem when the phone switched off once connected to a charger. Try cleaning the port with tissue paper. Push it into the port with something small and thin. You will probably see some dirt on the tissue paper. You may try cleaning the USB connector on the cable as well
Hey guys same problem I bought my pixel in letgo and the charger was very losse and fell out by its self call Google and they sent me a replacement it's all good now

The big question:
Charging port or battery?
is there a more appropriate forum for this?
Just from the thread its is clear the problem would be with both. When the charging port is not functioning well, it greatly impacts on your battery, and that could render the battery not holding charge for long.
