Hello everyone. I just want to start off saying that this is NOT a question about USB charging. I know about the trickle charge/lack of voltage stipulations. This is about the factory A/C adapter and USB cord I got with my transformer.
About 80% of the time I plug in my tablet to the A/C adapter, literally nothing happens. The screen doesn't turn on while in sleep mode like normal, the battery in the bottom corner doesn't change to a little lightning bolt, and most disturbingly, my tablet will not charge. The weirdest part is that it connects to the computer through USB no problem. I can move files and such, but no charging. Any ideas?
the charger construction is marginal at best and may need to be wiggled to get a good connection. also the usb connector an be plugged into the charger incorrectly. remember the usb connectot on the supplied cord does not comply s
with the usb spec. Also chev
ch the country ac side adapter ther are also unreliable
My cable went screwy and now it only trickle charges, regardless of what it's plugged into. I've got an RMA for it, but since I have to send them the cable to get a replacement, I'll have a paperweight for a few days at least.
Are you sure yours isn't trickle charging? There wouldn't be a lightning bolt, but I does charge.....very slowly.
Unplug the AC adapter from the wall for about 20 minutes. Plug it back in. Plug in TF.
Charging now?
unplugging it for a while seems to work better than anything. I'm pretty sure there isn't any trickling going on.
You can also try using the charger for your phone if the plug is a USB type. There have been a lot of problems with these charges documented in other threads.
Unplugging it definitely isn't a solution for me. When it first started happening I could do that and after a little while it would start working properly again, but now, it has charged at normal rates in about 3 weeks. I'm going to send it in with the RMA, but I have no idea what the turn-around time is. I'm going to be without any way to charge for that time, which pisses me off just a little bit.
I am having trouble charging my tablet. When the tablet is on, I am unable to charge with either the POGO or USB cable. I have also tried other wall chargers for cell phones. I was not using any roms, but had tried out the ktmantra kernel. I have since wiped my tablet using a factory 4.2.2 image from google and am still having the charging problem.
The only way I am able to charge is by charging with the tablet off. It also takes ages to charge (12+hours). Any ideas on what could be causing this? When I plug the POGO cable in, it says it is charging, but the battery percentage continues to drop.

I've readed some comment on another forum from an user that has the same proble, but for him it takes about 10h. Not sure what's wrong.
Are you not able to charge at all or just very slowly? I just noticed that my Nexus is charging very slowly with the Pogo cable I purchased. I may try going back to the usb cable to verify that the problem is with the cable and not with the tablet.
I was getting very slow charge rates with my usb charger. Around 12 hour charge times even when completely powered off. Anyway, my problem was with using a USB extension cable. Since I started plugging it directly into the wall I've been seeing charge times in the 5-6 hour range. My iPad never had an issue with it, but whatever! You might also try a different wall outlet.

I cant seem to solve this problem. I have tried using pogo and usb cables with two different chargers. I have also tried using different wall mounted phone chargers. I am not able to get any positive charge while the tablet is on. Using the battery monitor widget, I used to see a +1800 charge with the pogo, and a bit less with the usb cable. Now, the highest I get is -500.
I am only able to charge when the tablet is off, although very slowly. I had it charging all night, and it is now at 60%
When I plug the pogo cable in, the tablet will say it is charging, but it really isnt doing anything.
Any ideas?

Recalibrate battery? It's probably not going to work though. RMA the tablet as a last resort.

How can I recalibrate the battery?
Im in Europe until June, so Im assuming it wont be easy to RMA.
There is also a strange thing going on with the usb cable. My computer is unable to detect it as a storage device. When I plug the charger in, it will not show up as charging when the tablet is on. But, I am able to access the tablet via fastboot.
Where is that oficial pogo charger from samsgoogle? 4 month and counting... 2 Biggest companies în the world are unable to produce a simple cable... Hillarious

The N10 charger is a 2 amp charger and most phone chargers are 1 amp chargers. The N10 will charge slowly with a 1 amp charger if it is powered off, however it needs 2 amps to run the N10 and charge at the same time. Also I have found that not all USB cables are created equal, you may want to try another usb cable. I do not know anything about the pogo chargers. Hope this helps.
Last night I was charging my S4 in my car adapter, but noticed the cattery was still going down. I went home and plugged it into my AC (wall charger) and went to bed. The next morning the S4 was dead and couldn't charge. The only solution was to plug it in my computer and went an hour for it to get some charge back.
I have a root i337m running rootbox 4.1, and I went into TWRP to wiped the phone and installed the ROM again - no luck.
Is this a battery issue, a software issue or a whole device issue? Thanks.

I don't think its a rom issue. I tried charging via USB as well and had phone charging a few hours and it ate crap. So I only charge via AC outlet only. USB charges but at a very slow pace.

I made an error in the OP - I meant to say I left it to charge on the wall and I got nothing.
Right now, the charge light doesn't even come on if I plug it with AC.

Maybe see the results by changing the charger you're using?

I've tried 3-4 different chargers and cables, same issue. Charges slowly through PC,doesn't charge at all with AC. Did a factory reset after reverting to stock FW, no luck.

I doubt it's a ROM issue, but there's no harm in reverting back to stock to see the results (assuming you've backed it up). If it all fails, i think you should unroot and send it to Samsung for the warranty. Software problems are somewhat easier to fix here than hardware, so it may be the best option to let Samsung handle it.
I had similar problems with my Note 2 before and now with my S4. What I found was, sometimes the usb cable wasn't tightly plugged into the wall charger. Once I've made sure of this, I've been able to charge (AC) every time.
I found this article that indicates that the S4 is looking for special sauce on the D+D- pins.
http://www.anandtech.com/show/6914/samsung-galaxy-s-4-review/2
Obviously the Galaxy S 4 will charge with any USB charger, but the charge time will simply be longer. Samsung uses a voltage divider and signals the presence of their own charger by sending 1.2-1.3 V across the D+ / D- pins, this is similar to what Apple does with 2.0 or 2.8 V across the pins for various USB chargers they've shipped over the years. This signaling is essentially Samsung's proprietary tablet charging signaling which they've employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it's worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging.
However I do not believe this to be 100% true. I think not all chargers will work..
I took a charger that is very vanilla (Wall charger but the D+D- pins are NC) and it works with the S3 and NEXUS7 but does not work with the S4.
This charger uses a stock USB cable so I took a wall charger that had gone bad but had a dedicated cable and hacked off the end and wired up my own cable...
That works! So it appears that the S4 will only charge properly with certain chargers that do something to the D+D- pins (either shorting them with a resistor like the article indicates
I then took a look at the cable I used to replace. It is a Motorola cable and it has the ID pin pulled high built into the cable... So I suspect that is required for the phone to work... But to fast charge it will need the special sauce indicated above!
Had the same issue and found the solutions which worked for me. Go into the developer mode and deactivate the usb debug mode.
Had the exact same issue. I took a soldering iron to my charging port on my phone. Problem solved. The ID pin had a bad joint.

I have a strange issue, my s4 is detected by pc, charges normally with usb ( wall or pc charge ) my battery is full but when I take the cable from microUSB port and s4 should work with the battery, turns off and consumes no battery, it's like refusing to use the battery and that it is full! battery checked on a sph l 720
I've tried installing other roms with safestrap but I still have the same problem, refuses to consume battery and while the battery is at 100% ,my s4 shows 0% if I disconnect the usb cable... game over. However, I can be on the safestrap menu for hours only with the battery, no problem, is a problem of rom I think but did not know how to fix it .. : (
I'm having the same issue as the original poster. The USB port is good, charges fine when connected to PC (although much slower because of different mVS). Have tried amidst everything and nothing fixes it. I've turned debugging mode off and back on, restore to backup, complete wipe and reinstall of 2 ROMs with and without apps, fix permissions, different kernels, different USB cables... The adaptor is in good condition. But when plugged in while on my phone doesn't recognize that's it's connected. Previously out would give a false charging reading. If off sometimes I got the grey bar battery but note is just vibrating every few seconds. Idk what to do...

I'd guess it's the charger. Get a new one

I had the same problem. S4 will recognize charger as USB charger, not AC. solution was to clean usb port connector, was some cloth covering wires. then restarted and worked ok
I am having trouble charging the phone the same way. I have reset the phone 3 times and still can't get a charge.
HELP! Used "incompatible" USB cable all night, now only charges w/ computer USB port!
Okay I know this sounds crazy, but I've tried 3 cables, 2 car charges, and 2 wall charges that all worked previously... And what I've found is that I can only get my LG G2 to charge when its plugged into a computer USB port. I've got car chargers that are both 1A and 2A, as well as wall chargers with varying amperage ratings too. And they all used to charge the phone and even still do charge my Samsung S3! Also the same USB cable that won't charge the phone when plugged into a car or wall charger, WILL charge it when its plugged into a computer!!??!
And to make things even more strange, Android reports the phone as "Charging", but the percentage never goes up. And using CurrentWidget or BatteryMonitorWidget, the phone shows as "Plugged In" but shows "DIScharging" and shows the mAh utilization as draining at 18mA...
The only thing I did differently is that last night, I used the USB cable that came with my ChromeCast device to charge the phone. I plugged it into the LG USB adapter that came with the phone. I didn't realize until this morning though that a message had popped up saying the phone was "incompatible" with the the charger/cable and that I should unplug it avoid possible damage..
Did that possibly break the charging capabilities?? That seems not possible...
:crying:
Gotta ask... Have you powered down and rebooted to see if that clears it up?

Unfortunately yes I have...
It's a shame you didn't see the warning message as soon as you plugged it in. Can you take it back under warranty? Sounds like it did do the damage it warned you about. The last ditch effort I would suggest is do a factory reset and see if that fixes it. If not, take it back.

Yea, I'm hoping not.. I may have to factory reset.. Boo... But I'm having trouble believing that a normal USB cable REALLY could do damage though.. I have another charger/cable combo that I keep plugged in on the wall in the kitchen and use it all the time for my S3. When I plug the G2 into that charger, it gives that same "incompatible charger" message. But what is so different about this phone that prevents it from being charged by any standard USB cable..??

I have a handful of charges at home and they all output different levels of power... though most are much less than LG G2 default charger.
Okay REALLY strange... NOW, the chargers charge my phone, but only show charge them.. Using the LG charger & cable, only slow charging is possible..
Seems my other charges are working now too.... Anyone have any thoughts?
I just got my Note 3 working thanks to this group. When I first got it, it was without a battery and was locked by PIN. I was able to wipe it to factory conditions, but now it will not charge. It charged right away when I first got a replacement (OEM) battery, but then, I did the system factory reset, and now it will not charge. I am using a USB 3.0 cable and connecting this to my Apple charger I got with my iPhone 6 as I don't have a specific charger that might have come with the Note 3...just a generic USB 3.0 cable and the iPhone 6 charger that the USB cable plugs into. Any thoughts for me to try?
Try plugging the cable into a computer. It might not charge fast but it will let u know if it will charge or not. Iphone charger might not be compatible so battery will not charge.

I have tried using the computer and that is part of my confusion...the phone will indicate it is charging...but it doesn't. I get the same indication whether I am using the computer with USB 3.0 cable, or using various wall charger pods with the same cable. It will show the charging symbol (lightning bolt) or, if turned off, but plugged in, it will show the upflowing green drops rising toward the battery. So, it seems to indicate it is charging, but the charge percentage never increases...only drops.

It's not unheard of for a brand new battery to be defective. If you know someone else with a Note 3...try swapping batteries with then and see if the problem moves with the battery.
There is nothing in a factory refresh that would effect the charging circuit.
