Does it charge on the wall okay? I would try a different kernel out, see if that remedies it. If not, I would be suspicious of a damaged/faulty USB cable(they do/can go bad), or a faulty battery. Have you tried clearing your battery stats yet? I would do that, as well.

I'm guessing battery too, sprint should have a machine to check it by the way...

It's happened to me a few times. Sometimes the cable wiggles or something I guess.
I just unplug and replug and its fine.

I've had this happen consistently over the past few weeks, only with my car dock though. It charges fine both in my dock at work and on the standard charger at home. I'm using a Seidio dock, and I've done multiple things to find the issue. Both my wife and I have EVO 4g's with Seidio car docks. I swapped my dock for hers, no change. I swapped out the charging cable, no change. I used a different charger, no change. I tried my normal setup on my wife's phone, no change.
I don't know what else to do to figure the issue out. I have ordered a new charger that supplies 2.1A, as I've read that a low charger output could be the issue.
I am confused, as this combination has worked fine for about 8 months now. Why all of a sudden is it no longer charging properly? The battery could be the issue, as I know that the chemistry changes over time, but I'd like to know for certain before swapping out the battery.
I'd love to hear from others who are having the same issue.

Seidio Dock issue?
I've seen a few other posts with the same problem. Particularly this one: Post #1175
http://forum.xda-developers.com/showpost.php?p=16499063&postcount=1175
The one thing that is similar is that he is using the same car dock as I am, the Seidio dock.
I've been playing with this a bit, and have managed to isolate it to the Kernel. I flashed back to MikFroyo and the problem disappeared. It charged perfectly fine.
In Gingerbread (MikG 2.42), with both the stock Kernel and the Freedom Kernel, the phone won't charge properly in the dock. I've been keeping an eye on it with Battery Monitor Widget. Here are the results:

While I am driving, the kernel is showing a 100% full battery, however, it is discharging instead of going into the float mode. As soon as the phone is removed from the dock, it goes from 100% down to 80%. When I put it onto a desk charger, it charges fine with a normal float charge. If I remove the cord from the Seidio dock and plug it into the phone (with a mini -> micro USB adapter), it will charge normally and go into float mode.
Something was changed in the GB Kernel update that affected this behavior. Unfortunately, I'm not a programmer to get that deep to find out where the problem is.
Is there any help possible from anyone???

This always happens to me on AOSP roms. If you happen to be on an AOSP rom, just plug the charger back in then take it out.

I've tried that previously with no luck. I'm using a Sense ROM, currently MikG 2.42, but I had the same issue with the stock GB ROM.
Thanks for the suggestion.

For those with charging issues [Possible Solution]

There have been quite a few people that have come into one of the IRC channels for this phone with complaints of very slow charging batteries. There have been a lot of theories regarding the slow charging, but after testing for about a week I think I may have a possible solution.
Many stated that they were using USB ports on their computers or USB hubs, while others stated that they were using the wall adapter's from their old phones. The problem with this is that, although USB 2.0 ports have 5v output (the same as a wall outlet), they only MAX out at 500mA (milliamps) or .5amps. USB 3.0 ports output at 900mA, so this is almost twice as much as 2.0...but still more than half as low as the wall charger. Also, not all wall adapters will handle the same electrical output. They range anywhere from .5amp through 2amps. The one that Samsung bundles with this phone is 2amps.
So, if you are experiencing extremely slow charging while connected via USB to your computer or hub (or even using the wall adapter for your old phone) then you may want to charge your phone via the supplied wall adapter. I realize that its probably inconvenient as most like to connect their phone to their computer while they are at it, but you can't have it both ways. And for anyone that thinks that their USB 2.0 ports are somehow magical and their phone charges more quickly than others through this method, it's not possible as 500mA MAX is the industry standard.
I tested my, and my girlfriend's, phones for the last week, and this is indeed very much the case. Laptops can put out slightly more amperage, but it is negligible.
Charging tests were performed on 2 different laptops and 2 different desktops (one through a hub and one direct to the USB port on the PC itself).
Charging from dead via USB took ~8 hours (one actually took about 12 hours during one of the laptop tests) to fully charge from dead.
Charging from dead with the supplied wall adapter on either phone took ~2-3 hours.
Charging from dead using the wall adapter from the HTC Evo 4G took each phone ~6 hours.
I realize that this will vary in some degrees from user to user, but I think for the most part it will be correct. I also had two friends run similar tests (one used the Evo 4G charger and one used the Evo 3D charger) and their results were very similar.
Most of this is probably common knowledge to many people, but for those that didn't know, I hope this helps.

Umm...the charger included is rated at 1A?

My Battery Won't Charge @ All

So Yesterday I put my phone on the charger and noticed after 2 hours it stayed at 5%. And though just to restart the device, however that didn't work. So at 3 am in the morning I turned it off and threw it on the charger over night woke up to find its at 1% as I type this now.
Is it my battery that's done for or my Note 3 HW?

try new cable and charger base. If neither work, call for replacement.

Or get a new battery save yourself the time you'll have to wait to get another.

It's probably the usb cable, mine went out a month ago, same thing happened to me it wouldn't charge tried another cable battery charged without any issues. So more than likely the cable is bad.

Well I ordered two new anker batteries along with the external charger, and that but that's my problem nothing wrong with a charger or USB cable. My battery just simply would not charge it could not hold one anymore, I literally put it on the charger the entire night and the phone stayed at 5 percent and then as soon as I started do anything on my phone it literally shut my phone off while on the charger during a text message.
I guess it just died.

This same thing pretty much happened to me. Actually exactly the same thing... including the extra Anker batteries and charger as well as testing different cords. I ended up ordering a wireless charging kit, and now all is well. I've been using it with one of the Anker batteries. I ordered the Koolpad charger and the white slim wireless chip off of Amazon. It charges through my Seidio case, and I put velcro onto the charger and the back of the case so that I could easily use it while charging. The wireless charging kit cost about $40 on Amazon (I imagine pretty close to what a new official Sammy charger and cable would cost) and the Koolpad charger came with a black and a white micro USB (not USB 3 but still...) port cover, which I thought was a nice touch.
No guarantee that this would work for you, of course, but it did for me fortunately. If it didn't I would have taken it back to the store (after re-flashing the stock ROM, which may have solved the problem on it's own). Oh yeah, not really sure if this is actually related / possible but I did theorize that the problem may have been kernel related. I had actually been following the wireless charging thread anyways, but if I wasn't already considering spending money on that, the first thing I would have tried would have been a clean install of everything. I was testing out different kernels with Tweaked ROM and the problem started around a new kernel flash, but really can't say if that's related because I was unimpressed with that kernel overall and flashed one that ran better on my phone around the time that the wireless charger showed up (got one day shipping w/ Amazon Prime because shutting down my phone to rotate batteries got old quick, as I'm sure you'll agree). Anyways, good luck. There's lots of good info in that wireless charging thread, if you decide to go that route.

When using GPS and charging in car, phone won't charge?

When I use GPS and want to charge from car charger, phone drops battery percentage, little slower then without a charger, but still dropping. So I thought that the charger is not strong enough, and bought another one with 3.1A, little better but still dropping. Then I try with home charger and no dropping, the GPS is working and battery is charging!
Is that normal, that the car charger can not charge the battery when the phone is in heavy use? The home charger have only 1A, and car 3.1A.

Try NOT using an original HTC cable but instead a generic cable.
I recently purchased an external battery pack to charge my phone while on the move, I thought it would be best to use an original HTC cable but found it was charging to slow, when I checked in settings- power it stated at the top that it wasn't Charging as AC.
I suggest you go to your car and plug in your phone
Then go to: settings - power, check if your phone is charging as AC, if not you'll need to try with another cable ( check screenshot)

I don't use original cable anyway, have other cable in car. Check it and it say AC.
Adapter is this one:

That's really strange mate, I don't have this issue, is there any possibility of trying a different car charger & or cable?, maybe a friend's just to eliminate it as a possibility.

I tried today different things, original htc charger and cable, different charger and cable, and all of that in different car...
The best was with original htc charger and non-original cable. Phone start charging and i think that was that, BUT...
After approximately half an hour, start discharging again, and i think that i accidentally move the cable, but the red charging led was glowing. When checked in power settings, there say "discharging". I disconnect the charger and connect again, start charging but after a minute it stop. Some overheating, maybe?

It sounds like that could be the problem (over heating) maybe you should try a different kernel and undervolt a little to see if it will help.

Ok, I can try, I'm currently on Lyapota's 023 kernel and Viper X 4.1.1, everything else working very well.

I use #017 pre aroma and it runs very cool

Yes, lot's of people says that this version is the best, I would try it.
So, you try to use gps and the phone charging ok with Lyapota 017? Which rom you use?

I have not had any problem using GPS and charging, I use the lates t MaximusHD.

Ok, thanks, will try with 017 and report back.
Edit:
I didn't know that this is a very common problem, that the cable is the one who can't supply enough current. I found many articles about this problem, and found something very interesting on Youtube. Will try this tomorrow and report if it works.

Hi, higher charging rates are established via protocol negotiation or preset voltage levels on USB data lines, so in your N7 the following could be faulty:
USB connector
soldering of the connector
connection of the wide silver cable between PCBs
Attach your N7 to a PC and check if MTP works. If not, then one of the above will fix the problem.

How do I know if MTP works?

this started on mine as well. was going to blame the 7.1.1 rom I am running on it as it started the same time I flashed it. Try a wireless qi charging pad

mines charging at 475ma..is this normal or still low, using the official charger unit, but a megnetic cable
checked again, 810ma now

Mine had major problems with touchscreen and charging.
I did the following and fixed all the issues:
1. Disconnect the battery (lift the connector up to disconnect).
2. Disconnect the white flex cable on both sides (lift the little latch up and you should be able to pull out the cable).
3. Clean the flex cable connectors with 99% isopropanol alcohol and q tips (until no grey residue comes off any more).
4. Take out the usb board. Clean the the touchscreen flex cable the same way (the two smaller flex cables next to the white one).
5. Take out the screws of the USB board. Use the q tips and alcohol and clean all of the copper colored groundplanes.
6. Clean out the usb port with some alcohol, while you are at it.
7. Plug in a usb cable and check if it's loose in the socket, if that is the case, use some needle nose pliers and bend the port back to shape (be very careful). Then testfit the cable again.
8. Reassemble everything and test it.
This should've fixed your charge problems, problems with auto rotation and ghost touches, or bad touch recognition.
It has fixed mine
EDIT:
I started off with 50-100ma charge current (wouldn't charge over night) and can now charge with 920ma again (Anker charger and good usb cable).
