OK, so for some reason, when I charge my tablet and use it at the same time it doesn't charge but rather still discharges slowly. I am using the included ASUS transformer because it has a higher output... Supposedly. Anyway, I set my tablet to charge overnight and I wakeup and don't find it charged all the way. What is up?

Try charging it with the device turned off. If it won't charge then, you've probably got some sort of hardware problem (charger, power circuit, battery). Also try a different charger in case yours is dying. And try a different cable... i've definitely had some cheap ones that just wouldn't stay in the socket.

I'll try a different cable. That might be it as the cable is very easy to loosen. The tablet charges just fine.... just not fast enough. Reminds me of the old usb car chargers. The output would be too little compared to what the phone is using and it would discharge at a slightly slower rate.

My transformer died... and now it won't turn on. The battery was low, so it was probably that... but I thought I charged it.
So I now think my cable is no good. the charger is for sure fine.
Does anyone know what pins to test on my transformer cable to check for voltage? it's either the cable or the transformer port itself that's broken.
before dying, the usb transfer worked. but it wouldn't charge...?
anyone know what pins could cause that?

hmmm now it's doing this, which i've never seen before...
no i didn't change the bootloader. has anyone else ever seen this? http://i.imgur.com/6XvQF.jpg
Dead battery sign man, charge it. I never really hear about the cables going bad, the chargers go bad all the time though

Put the charger in a plastic bag and throw it in your freezer for an hour. Take it out and check to see if it works then. It probably will.

Try to trickle charge off computer and see if it is the block. If it is then put in the freezer like Gary said. But my cable stopped working to transfer data so I had too buy a new one. So Maybe it is the cable?

I also find that sometimes the charger goes "dumb" and you have to physically unplug the block from the outlet or surge protector and plug it back in for it to start charging again. Have you tried this? See if you can get it to charge by doing this, otherwise I second testing the USB cable portion only by connecting it to your PC and having it charge through USB although this is very slow and will take a long time. It also won't charge if you're using the tablet since USB doesn't supply enough power, it might also not charge if the tablet is on at all I believe. Just make sure it's off ad leave it on USB overnight.
I think my friend's just had the same exact problem since last week. It just suddenly stopped charging. My friend though his transformer died.
The cable won't charge but if connected to a PC, it will recognize the tablet. It will not trickle charge. I am going to RMA the cable.
Do you have a USB extension cable in series with the TF cable? The charger needs to see a gnd on pin 7 of the USB connector. If it doesn't it will only charge at 5V and it takes days to charge with the TF off. If no extension cable, plug in to a powered computer and leave TF sit for 10-20 hrs with TF off. It will charge slowly, but bring battery level back high enough that the TF charger will not think it is shorted and shut down
Thanks everyone for the help. It trickle charged, and is now at 96%.
i'll keep everyone updated.

So did the freezer trick work ?
Sent from my Nexus S
So I went to plug in my phone using the stock charger and it would not charge. The charger would however charge other devices including my N7. I tried several different chargers and none would charge it. My N7 charger was here at work so I could not try that until now. Plug it in and instantly charging. Why would the N4 charger quit working on the phone but still charge other things.
Im so confused!
It probably has something to do with the terminals inside the connector. They must not be making a solid connection
the wall plug in part of the stock charger is junk. mine makes a loud ticking noise and gets really hot. i don't trust it, i use the stock charging wire with an old HTC plug in and its been problem free

Just comparing my S3 with my sisters S3, i realised that the bundled usb cable is actually thicker on more recently sold phones.
I noticed this after trying different chargers to try getting her phone charging properly again, and found that her thinner cable was providing less power then say a completely hard wired travel mate charger, In result, her usb cable was providing enough juice to maintain a level of charge but not providing the power necessary to charge it.
I'm used to LION battery circuits being on a switch setup, so that the device is powered completely from the external source during the charge, however the charging on these phones (and possibly other samsung phones) passes through the battery itself, so it does seem that inferior cables can and do affect charging times, atleast while the device is operating.
So to those complaining about slow/no charge, check the quality of your bundled cable, the thicker cables are certainly harder to bend and feel more durable than those sold with the phones earlier in the year.
I found that a good way to check this is when the battery is at 80%, a good quality cable or travelmate charger will increase the current voltage value in battery stats (*#0228#) from 4000xish to 4250+ upon plugin. The inferior cable (or maybe it was damaged even?) may increase it to 41xxish and the battery will appear to take forever to charge, or not at all.

Is there a way to see the charging current?
Have u check the five pin on the cable? Mine missing 1 pin, making the charger slow. Already compare it with working charger.

The 4th (or second, depending on which way you're looking at it) pin does not exist on any USB to micro or micro USB adapter cables.
see http://forum.xda-developers.com/showthread.php?t=1174919
standard usb plugs only have 4 pins, 2 for data data, 1 for ground and the last voltage, so this extra pin is never available on any adapter cables, including phone charge cables - its not even present in my travel mate charger, so that pin missing has nothing to do with the slow charge.
I am very sure that my wife charger have 5 pin and working fine, and mine lost 1 pin very slow in charging. We both using the same phone. Btw, I am referring to the pin that's connected to the phone. Not the one to the plug.

Sometimes when I charge my phone I get spikes of charging then not charging. Wonder if this is a problem with the USB port or its just a dust issue there?

I think this phone just has a retarded charging port. The plug doesn't stay in securely which causes the phone to charge slow, first of all. And I recently started having the problem you described. It will say charging, not charging back and forth a bunch of times. Are you using a case? When this happens, I take off my case to make sure the plug is in there securely and I also make sure the AC adapter is plugged into the wall securely and that the USB plug is plugged into the AC adapter securely as well. This usually helps.
Charging this phone is such a headache sometimes.
That happened to me like a month ago and the charger was the culprit. But I also had slow charging (even with the wall adapter, it would eventually change to USB charging) and it wouldn't reach full charge. You might want to try another charger, just in case.

I've seen this also and cleaned my USB pins...seemed to help.

I have to agree. I am using a different charger because the one it came with sucks. I would wake up to a phone that had 50% even though it was on the charger all night.

My Nexus 4 does this when I use the LG USB cable, but I don't remember if it happened with the stock charger. I lost that a long time ago, and now I use the charger from my old Motorola Atrix, which works fine if I use a cable other than the LG cable. I think my cable is damaged, but it feels like the cable always did that. If I plug my dads Atrix HD into the LG cable, it does the same unstable charging as my Nexus.
I have the same issue, have tried multiple chargers and cables, even happens over Qi.
I have a replacement phone coming
Had this too, charger was broken, just try another charger first.
I'm now using a standard samsung charger
I had this problem with the official charger, but it works well when I charge it using my computer usb ports (I prefer lower current when I charge over night) and the Nexus 10 charger.
Thanks for all your responses...it seems to be better now after cleaning the ports....but still happens sometimes...I'm trying to do a RMA for it but have a question...what if during their testing it didn't happen would I need to pay for the replaced device?

Have not had this problem myself. Try another USB charger? Just about anything that's 500mA will work (albeit not nearly as fast as the 2.0 amp charger that came with your phone).
I suspect your charger.

It was the cable. I really didn't suspect it would be that since I have barely used it and I've only had it for two weeks. Thanks!

Good to hear it was a simple solution. You might check with the place you purchased it from to see if they will provide a new cable. I guess we can just be glad you didn't find out about the cable during the middle of an Odin flash...

No kidding. That would hurt a little
I am now having this problem after my phone got wet. No AC or DC chargers will work but the phone will always charge from a computer or even the USB interface of a car.
Even if I can get an AC or DC charger to be recognized, the phone will show as charging but the battery will continue to decline.
It is making no sense to me though I assume getting the phone wet partially fried something.
Yeah the voltage is increased to charge you battery when on AC power, at the kernel level. USB voltage is lower. So i'd say surely fried, and will no doubt stop working sooner or later.
I know that on my s2 I had an issue where it would say its charging and when I woke up in the morning no charge at all. The pin/row of pins or bar if you will would bend down and not make good contact. I used a tooth pick to pry up on it every time it did that.

Thanks. I didn't realize that the charging port was removable on the S4 so I swapped that out and all is fine now. :good:
Ummm... No its not the voltage. It is the ID pin. The voltage stays the same. The only actual difference is the milliamp mAH output of the charger. A normal USB plug has 500mA our charger has 2000. How the phone tells the difference? The 2 data pins inside he charger are shorted together. The voltage always stays the same.
