Randomly my note 3 has started having issues charging. I'm not quite sure why. It gives an error about needing the factory charger, however I'm using the factory charger and usb 3.0 cable. Sometime a reboot fixes it, but not always. I've tried using different charges, and even a regular usb 2.0 cable and it still does the same thing. Is the port maybe going bad? If so, has any one replaced theirs? Any help is appreciated. I have wireless charging, but there are definitely times I need the quick charging of the oem charger.

You might want to try a factory reset in the settings menu. Just back up first. http://forum.xda-developers.com/showpost.php?p=50920218&postcount=17
I'll give it a shot if it continues, I'm rooted so I can easily back up my apps and such
That is the problem with intermittent behavior. It is difficult to say that "after" is caused by "before" because you don't know when the intermittent behavior will show up and when it will not. Any experiment in the presence of an intermittent behavior runs the risk of coming to a conclusion that is an "ex post facto fallacy".
I suppose your hypotheses of a damaged or loose USB connector is the most probable, given everything else you mentioned, although since you don't have a second Samsung/OEM charger, a problem with that specific charger can't be ruled completely out.
Note that the USB 3.0 Micro-B connector "extra" pins (the part of the connector which is not used by a USB 2.0 micro connector) doesn't have power/ground in it (there is a shield ground, but this isn't the same thing as the power supply ground)... so your tests with a USB 2.0 cable don't resolve anything about the connector, but do indicate that the problem is probably not your Samsung OEM USB 3.0 cable.
Those mini-usb connectors are pretty horrid mechanically for devices that need to be plugged in several times daily; I guess the phone industry assumes that consumers will toss their devices after two years, so the power connector only needs to survive about 1000 - 2000 plug-in/removal events.
The only conclusive way to eliminate the possibility that you simply have a failing USB connector would be to use a spare battery charger - and that means buying both a charger and a spare battery if you want your phone on almost 24/7.
Sorry I'm not more help.
My 2 cents...i had this problem while using custom rom..however, taking the battery out for about 30 sec..switching back to stock Rom using safestrap rebooted and it all went back to normal charging ok. Went back to custom rom again no issues after that...

I tired this last night and unfortunately it didn't fix the issue. I have multiple OEM chargers and none of them are working correctly. Once my wife gets home today I'll try her cable to see if it makes a difference. I'm really hoping I can get this figured out because I have never received a good refurbished phone from vzw under warranty. I may even resort to just using the wireless charging and ordering the oem battery/external charger combo. Has anyone ever replaced the port itself?

FWIW
I have never done this repair, and it's not too encouraging that the iFixit teardown in Step 7 mentions that the USB connector sub-assembly is "glued to the phone". (Looks like step 5 could be skipped maybe).
I note that the images in this eBay listing shows "SM-N9005" stenciled right on the assembly ... I wonder if this sub-assembly would be any different from carrier to carrier? Seems sort of unlikely that Sammy would silk-screen a specific variant Model # on that assembly if it were the exact same part on all variants. (But maybe you can inquire of the eBay seller - at least the piece prices are pretty inexpensive). I didn't spend much time searching; maybe there are other sellers with the SM-N900V assembly.
good luck

I found some videos on youtube of people replacing them, it seems like it's one of the easier parts to replace on the phone. I'll probably give it a try. I'll post the result if that fixes my issue. From doing some reading about the part, it is semi carrier specific because where the antenna cable goes. I'm hoping to get this done sometime this week. For now I'm just using my wireless charger to make due.
That does make a bit of sense.
If you find a supplier for the SM-N900V part and it's in the same price range, send me a PM with the link... I might buy one on speculation (I typically don't buy a new phone every two years so it might be a good idea to have a spare part on hand just in case the port goes bad).
I installed a new usb port and now it seems to have fixed the problem. My usb 3.0 cable fits snuggly again and I'm not getting any weird messages. Hope this helps any one who has the issue

I'm glad you were able to fix it yourself.

Good news! Do you have a URL for the part supplier?
I experienced this today with my Note 3. I have all kinds of charging cables and right now after a few reboots a random USB 3.0 charger that I got from Amazon is doing the job. I noticed the phone no longer charging when I plugged it into the USB 3.0 port in my computer last night but I was doing a heavy amount of tethering so I didn't think all that much of it at the time.
