A word of warning - I received my USB 3.0 extension cable from Amazon yesterday, plugged it in when I got home and it started to charge. I noticed after a few minutes that the charge icon had disappeared and now the charger does not seem to work at all; tried both dock and tablet sockets.
This was the cable recommended from the other thread on the forum about charging the device.
http://www.amazon.co.uk/gp/product/B003QZKMU4/ref=oss_product
I'm fairly sure that it is the UK three pin socket part that has died as the machine is picked up by my PC over the USB cable. I've tried the usual taking the thing apart and re-clipping it back together, I've even checked the teeth on the cable to make sure nothing is damaged, still no joy.
I've emailed Asus support but after reading through the forum I'm not overly positive that they will be any help at all. I suppose I'll have to wait for the Chinese/Hong Kong factories to start kicking these out on Ebay as there doesn't seem anything in the UK at the moment. So I'll sit here and watch my 90% battery slowly die and the machine get covered in dust.
Why don't you get a cheap ipad charger in the meantime. Takes longer but do the charging overnight?
Thanks for the tip. Is the propriety charger the same or do you just mean the USB wall plug end?

My PSU died, and after a week of back and forth to ASUS service they have declared my TF DOA and told Comet to replace it.
They are doing a doorstep swap tomorrow for me.
I have also posted about PSU's with a known fault, look in the accessories forum
I had the same issue. For me i fixed my PSU by unplugging everything for 20 minutes. Sounds silly but it works. Unplug from the wall socket, take the usb out of the PSU and the TF and leave it al alone for 20 minutes.

I checked my serial number a few days ago and it was supposed to be one of the ok ones.
I also took the thing to pieces as much as I could without resorting to a screwdriver. It's been left out over night and put back together a few times.
The whole thing doesn't look to be the best put together electrical item I've seen. In fact my Desire charger makes it look like some 5p Chinese shonk, oh err hang on a minute it is.
Just looking at iPad chargers now.
Same thing with me and extension off ebay one day after I got it. What I had to do was a factory reset to get it to show the charge icon. Now it's been fine since going on 2 weeks now.

Funny you should say that, I was all about to give up and then gave it the tap of life on the window ledge and it started working again. The annoying part was that I'd moved it from the usual changing point to test it out so I have had to very gingerly move it back.
It's still working but I'm not sure how long it will last. I think that maybe the USB lead must have move something out, which is odd as it was a really loose light connection. The upshot is the charger is now going to be left untouched and the USB 3.0 lead is going in the bin.
Not really a robust item the wall charger!
Yes, mine was one of the good ones too....

I second this.....same has happened several times to me when trying to get usb 3 cable to act as charger lead extension. Just leave it unplugged for 15- 20 mins and all ok.
Charger or dock battery??
I don't know the inner-workings between the charging adapter, the USB cable and pins - and the dock battery itself so I thought I'd throw this out there:
My dock battery has stopped charging. I can plug the tablet into the dock - have the dock plugged into the wall - and the tablet itself will charge (and the adapter will heat up) - but as soon as I remove the tablet, the adapter cools down, and the dock battery never charges (just blinks orange forever).
I've just been assuming all along that it was the dock or the dock battery that had gone bad for some reason.
But would it be possible that it could be a pin / cable / adapter issue instead?
I wonder if different pins control the charging of the tablet vs the charging of the dock?
I'm *hoping* it's the dock itself because at least I can still return that and wait for another to come in stock. But if it's the adapter or cable, it looks like I'd be SOL and have to send my whole freakin tablet back for a replacement!
I'm sitting on hold with Asus now because last night neither my tablet or dock would charge. I do not have the extension cable but have one on order from Ebay. I was planning to test all the pins on the cable while the unit was charging to figure out which additional pins are communicating with the charger to start the charge. While sitting on hold I came across this post and decided to try the charger again and now my tablet is charging. Will try the dock once I'm fully charged.
I love my TF but this charging stuff is micky mouse. I hear some people can charge connected to a PC, I have never been able to. Now I need to do some more searching to see who had what extension cable from where.
Check the thread link in my signature to see my finding for making a cable to allow charging from other sources.
It's all a bit of pot luck by the sounds of it.
Don't leave it on charge over night, don't plug the wrong sort of USB lead in and don't move the charger.
I think I'll be buying some £2 Ebay charger as soon as they appear, can't be any worse.

A sense of panic set in when my charger stopped working after trying to use a USB 3.0 extension cable I purchased from Monoprice. After following this simple suggestion, I'm happy to report that all is working once again.
I never did get the USB 3.0 extension cable to work though. It was one that others have reported success with too. I guess I'll be sticking to a cheap extension cord for now.
This extension from CompUSA works like a charm. Its prices is awesome too. The adapter charges TF/KB seamlessly for me. Spread the words.

Ultra also makes this cable in a 12 foot length. Part #U12-40579. I have both the 6 foot and 12 foot lengths and they charge my 32TF and dock without issues.Both can be purchased from CompUSA.
So, I'm traveling (for a long period of time) with my TF. One day, it stopped charging.
I took apart the power brick and put it back together, I even tried to freeze it (on advice from some older "not charging" threads), nothing helps.
When I connect the TF to my laptop via USB - it recognizes the TF. When I connect my iPod to the power brick (with its own cable obviously) - it charges just fine. So what broke?!
I hate this, the local stores here don't sell the power brick separately and I don't even know if that's the source of the problem.
This sucks
Sounds like the power pin in the TF port has bent/broken or just has some detritus/dirt/foreign matter in it and is stopping it from charging properly. Have a look, but you might need to check the port with lots of light and a magnifying glass, so not easy while you're on the move.
If you are in the US Office Depot sells the charger and USB cable for $30.
strange thing is that sometime my transformer doesn't charge.
i have to reboot and it start to charge again.
Same happened here. Asus tech wanted me to wipe the device. After trying other options to get it to charge, I did but it didn't wipe... Go figure... But it booted up normally and now it has been charging.

Apparently charging has some history of issues on the TF101.
I just had mine act up on me, went around the house trying different wall sockets and checked that it worked fine via USB to PC. Ended up taking a can of dust-off to all the pins, then shoving the plug hard into the TF101 socket. Now it works.
Should have mentioned I have a dock as well, which doesn't charge either (so problem is probably with cable/brick)
I'm trying to get new ones (nowhere to be found here, but I'm trying to get one sent to me). I tried looking for dust/dirt and different wall sockets, no luck.
Weird thing - I left it plugged in to the wall overnight and it grew from 5% to 15%, so looks like some electricity is trickling.
I had the same problem with mine after I had it for 5 weeks, I just RMA'd it and everything is fine.
Im having the same exact problem. I left it charging over night by mistake the night before yesterday. I only let it charge 3 hours the most because I know the Transformers have known issues.
I tried to charge it this morning and nothing. I plug it into my PC. The PC recognized the Transformer but no charging. Turned it on and off, nothing.
Just put the power brick in the freezer, waiting to dry up to see if it works .
Although the tf charger and cable has a usb connector it is not usb compliant. the charger brick looks for a gnd signal on pin 7 of the usb connector ( normally a usb 3.0 data line) to determine it should supply 15V to the positive charge pin vs standard 5V. The slow charge you are seeing is from the 5V supply . check to see if pin7 is seeing the gnd signal. Are you using a usb 2.0 extension cable as it doesn't have have pin 7 conductor. be careful connecting your ipod as it could accidentaly see 15V vs the 5V it is designed for.
Ok, first a little background on this issue...
After having my S3 for about 13-14 months I started having charging issues. The charging port was very "loose" and I had to make sure my charger cable was in just right to get my phone to charge. This was annoying, however was out of warranty and didn't want to pay vzw for an insurance claim. This got worse, and eventually I noticed my phone would only charge with 1 specific usb cable, 1 specific wall charger, and 1 specific car charger.
Well, I finally called Samsung and explained the situation to them and they had me chip my phone to them and they would repair it, free of charge. When they had it, they replaced the charging port, the headphone jack, and the screen. I received the phone back after couple weeks, super excited, and immediately charged it up with the cable I had next to my bed. New charging port felt perfect, nice snug fit, etc... Well, after a few days i hooked it up with the original usb cable that came with the phone, nothing happened. So i started messing around and realized that the only usb cables that will charge my phone are Motorola brand cables! At least the 2 cables I have work, and not a single other cable I've tried works! This includes stock Samsung cable, many cheap 3rd party cables, other friend's S3 cables, none work. Also, I have this cheap car charger that is the type you plug a USB cable into that works, however any other car charger I've tried does not work either.
Also, when i say the cables won't charge my phone, it also won't connect the phone to a PC. They do absolutely nothing.
Does anyone have ANY idea why this is happening?!?! It was an issue before Samsung repaired my phone, they replaced the charging port, but I still have this issue!! I can send it back to Samsung for them to look at it again, however my backup phone, a Razr Maxx, just died also. Seems like the battery went dead and now I can't get it to charge, but that's another issue.
So, any ideas?!

What rom/kernal
It doesn't matter. It does this when it is totally stock and rooted. Right now I'm not rooted or anything because it looks like it may be going back to Samsung again.

I think the smart charging circuit may be messed up
Really? How would that cause the phone to not work with any cable except a certain brand?? I'm just really curious and this is driving me insane!!

I would say you are putting mechanical stress on the charging port. This could be from some misaligned or mis-made cable or somehow pressing or pulling the charge cable when its connected. I've never seen this reported by anyone else, but the mechanical connections are not indestructible. If it were a common symptom with 100 million S3s having been sold, there would be a firestorm of complaints.
I have a similar issue. I'm not sure if it's the device or the ROM (CM nightlies).
Certain cables force the screen to turn back on, which means I get negative charge because the screen burns more than the charger is capable of supplying. Other cables are fine. I'm still looking for the pattern, it's super annoying and causes me to have to turn my phone off completely at times so as not to lose my battery altogether. I'm still trying to solve this, any help would be appreciated.

Further info- it's not the cable, it's the converter at the end. I think it has to do with amperage of the charger- if I use the stock samsung one I'm good, it's putting out 1.0A. If I use others that are fewer amps (like 700 mA) it's unpredictable. I suspect a kernel thing, I might download different kernels to play with it.

Always use chargers that is 1 A - 2A the circuit controls most of the charging regulating amps and voltage
Yes, I agree about using good chargers, but my phone wasn't always this way. It used to charge with anything, but no longer.
I enabled fast charge on Imosyen's lean kernel. That might have made a difference, but I'm not positive yet.
I have looked around on this topic before posting, but nothing applies to what im experiencing
Up until this morning, I haven't had a single issue with my USB port or charging in general.
I clean flashed Purity KitKat, flashed compatible Uber kernel and installed my apps as one usually do, and let the phone charge for a while. A few hours later, I realized my battery was at 0%. I started panicking, looking for a USB replacement part, which I found for about $12 on Amazon. I decided I would download GSAM battery monitor to see if there was an issue with my charging cable.
What I saw was the mA flow was acting erratic, sometimes shooting from -700ma (yes, that's negative 700) all the way up to 1800mA. Even by just rotating the screen, it would drop instantly. . The phone charges, but a little at a time. I disabled KSM and fast charge which seemed to have a positive effect.
I'm not sure what caused this, or how to fix it, but I've attached a couple pictures to give you an idea of what I'm seeing. If it is in fact the USB port, would using a Qi charger be a good option or should I just go ahead and dismantle the phone and replace the USB port?
Note: windows still recognizes the phone and I can send files from the computer, and the charging bolt is showing.
Have you replaced the cable? Far more common for the cable to crap out then the port. Cheap or broken cables will appear to work, computer will detect phone and even display a charging indicator but it won't actually charge. Had happened to me in the past.

Yeah I've tried numerous chargers including my car charger. They all charge, but it took 12 hrs from 0 to 100

Try flashing the stock rom to rule that variable out. If you want to be sure that is the usb port you could try with a wireless charger as it could also be the battery, you can find a new one at the same price range of the port.
It does seems a lot like what happened when both the stock charger and the cable were damaged. I tried to charge the phone and when disconnected it had less charge.
So I've been using this phone for 5 months or so, and I've discovered a very unsettling thing. The charging cable has started to get loose while plugged in. This happens most with my third party charger at work (which wont stay in on its own), but also with the original charger I have at home. I cannot charge and use my phone in bed, because with the slightest shift the cable disconnects.
This also happens with the USB-C headphones and dongle, they wont stay connected while listening to music. Now, I mostly use bluetooth earbuds (which makes this weirder, because this should put less stress on the port) but this is just not acceptable.
I've calculated, and with every night charging, with some extra times for music and such, I've plugged/unplugged a cable only about 200 times. Does anybody experience the same issues?
Same here @xxxmarienxxx . Just started with this issue this morning. It was all good until last night. Any solutions yet?

I had this problem with my Moto Z Play. Have you checked to see if there is any debris/lint in the usb C port on the phone?
Sorry for stupid question/proposal, but could it depend on what phone case you use or rather combo of phone case and USB cable. I use the standard case supplied with the phone and have no problem with standard USB cable nor the standard headphones, but I have similar issue with a non standard car charger. When I remove my case it works just fine, ie it is not loose.
I've had my phone for 7 months and I would say I charge at least 2 times per day (to work and home from work) and I use headphones at least ones a day.
Yep. Same problem here . Already using a new cable for a few months ?
Was there ever a solution to this issue as mine is doing the same but will only go half way in, no debris and nothing is bent out of place in either cable or phone charging port.
Same issue, contact Huawei support.
Visited the three shop today and the girl told me this was a common problem. She showed me her phone and the cable goes all the way in, mine only goes about 3/4's of the way in and had been fine up until this week. She told me there is a 2yr warranty that they will/should honour. (Huawei). Going to contact them later and will let you know how I get on.
Charly.
Charging pin issues
Hi guys, if you're battling to charge your p20 cos plug cannot go right in.. Just use a sewing needle put it into the port and scrape off, u will be surprised as to how much muck u will pull out.. Give it a try
Cleaning with a needle
Thank you @Veejag. Using a needle worked perfectly for me. You were so right. I was surprised and shocked at how much dust and crumbs came out of the port. If you have this problem give the needle a go.
Mine also does that. One day supercharging wasn't working anymore, moving the plug, it alternated between fast and slow. Cleaned the usb port, supercharging started working, but the headphones keep disconnecting...
Scratch that, tried another pair of headphones, with the adaptor, they don't disconnect. It's most probably the cheap Huawei headphones' fault (they came with my p20 Pro)
