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?

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.
Hi everyone,
My first post as I haven't been able to find an answer. My Photon Q was probably about 30% charge when I last checked with it on. An hour or 2 later it was a little warm and was off. So I went to charge it using the car charger with 500mah charge rate. I came back about an hour later and the phone was really hot and no charging screen so I unplugged it. The green led light is lit when the phone is plugged in.
I tried holding the power button and volume down button, but it won't boot. If I have the usb charging cable plugged in from a PC or charger adapter when pressing those buttons, the green light will flicker off for a fraction of a second.
I then proceeded to dismantling the phone as I suspect a battery issue and the one in this phone is stupidly non-removable. After taking the back cover off, I tested the battery posts and received 0 volts. I still don't know if the battery caused the drain or if there's a short in the phone. I then took off the inside cover that holds the battery in. A few T5 screws later and the battery was removed. I connected the battery to some AA batteries in series to see if I could get a charge. A few hours later I got it up to 3 volts which held for several hours. So I connected it to a few more AA batteries in series to try and raise the voltage. I got it up to 3.67 volts and the battery is listed at 3.7 volts.
A day later and the voltage is still at 3.67 volts so I put the battery in the phone. I went to try and power it on, but nothing. I then connected it to a usb cord and received the slow flashing red led light a couple times before switching to green. The battery started getting warm again connected to the usb charger. After 20 minutes it was approaching hot so I unplugged the USB. The battery read 3.54 volts. 30 minutes later, 0 volts again.
Does anyone know what the actual voltage range is for this phone, as my old Samsung M320 is also 3.7 volts, but when testing the battery I get 4.10 volts? I heard it's pretty specific on minimum voltage. Any ideas for a temporary battery or way to boot the phone before spending $50 on a replacement battery and then find out there's a short in the phone. Is there another key combination to boot the phone, I'm trying to boot it to at least get my pictures and other data off it.
Thanks a lot in advance
Matt
Not the battery, seems to be an electrical short but where
I bought a new battery for the phone which had a 0 volt charge when I received it. I tried putting it in the phone as is to use the phone charger to charge it, but got nothing. So I charged it using 2, then 3 and then 4 AA batteries in series to get it up to 3.7 volts. I then put the battery in the phone and noticed the 2 large chips and the chip centered above them located by the camera get a little hot. I tried with the charger connected and not connected, but same thing. Power button doesn't turn the phone on. Just the green led lit when the USB power cable is attached. So now it seems there must be a short in the phone. Anyone know where I can look to check for a short, blown resistor or something in this phone? Or at least where the rom chip is located so maybe I can turn it into a usb drive to get my data at the least.
Anyone? I still haven't been able to find a solution. I don't see pins touching, but if some pins are touching in the usb port, would that cause the heat issues when I put a battery in that I charged externally? I do get the green led light when I plug the phone in to charge so figure that means the usb is ok?

did you try a other charger ? do you have oryginal photon charger ? for me its not a reason of battery
regards
(in situation like that charging with normal usb cable when you plug phone to pc dont charging battery, you need motorola usb service cable to make it work)

Yep used the motorola cable that came with the phone (plugged in the wall and just the cable in multiple computers, another motorola house charger (the same as the one that came with the phone), a motorola car charger, and a samsung house charger.
When you say motorola usb service cable, I assume you're not talking about the motorola cable that comes with the phone? What usb service cable are you referring to?

factory / sevice cable ( i make my own from below tutorial)
http://forum.xda-developers.com/showthread.php?t=1077414
if you buy / make this cable , you will be have posibility to use RDS lite and flesh firmware this also make help (if you have low battery flesh with normal usb cable is not possible )
and second thing... maybe try some car charger ?
I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

Ok, I'll give that a shot. Thanks.
I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.
I would try a new cable and Charger that is rated 2.1 amps or better if will be charged real quick

I noticed that using the Pure Nexus rom my charging time became significantly faster. In fact I can get a full charge from nearly dead in just over an hour. This is using the charger and cable that came with the phone.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

I read somewhere that if you activate airplane mode the battery is charging faster.
when i connect the cable every 1 min it stop charge and back charge again and in fact the battery is discharging if it was 55% it become 53% this when i disabled the fast charging in setting after android 6.0 marshmallow and when enable it device get hot very fast i could smell the heat easly? how to solve that
Sounds like a defective charger/USB cable/power source. In regards to it discharging and whatnot. Try with a different cable/charger/power source.
The heat is normal when you use Fast Charging, I thought everyone would've known this by 2016.
I use my phone's charger with a Sony USB cable. Because it has five pins on the inside, charges even faster than the four pins on my S6's OEM USB cable (and obviously more heat), the Indian version of the cable from Samsung has only four pins, they pulled one out, presumably thanks to idiots complaining about the heat.
I've successfully replaced the battery of the dock with a new one. It was showing some charge 36% instead of 0% and no more tablet draining, but it never charged! So now it's at 9%, red dot blinking, and I don't know how to fix it! Charging sign appears when plugged in and tablet charges trough the dock.
I've tried the cold boot and the trickle charge but I didn't see changes, maybe I've done something wrong?
What more can I do to make it charge again?
I thought it was the charger or the cable but for what I see the 40-pin connector has actually only the 4 pins (the usb signal) so I don't think I need another cable.

I don't believe it is a software issue. It might be a contact issue caused by yourself I think.
Firstly disconnect your tablet from the dock. Connect it with the charger and check if it is going to be charged. If so, your both charger and cable are OK.
Secondly check whether all contacts between the battery and the dock are closed correctly or not. Please follow backwards the sequence you used to taking out the old battery by yourself.
try and charge it with the official charging brick, or at least something that can put out 15V at 1.5A i had the same problem when using my tablet after a long time and only my tablet would get charged not the dock
Yes I'm charging it with the official charger, maybe it got some problems
I don't have a tester at the moment but I got a doubt. Is it possibile that the cable has 2 charging lines one for the tablet and one for the dock? Because I want to buy another charger but maybe it could be not compatible for charging also the dock.
I opened it again last weekend and there was nothing unplugged, everything was good.
