Honestly, I think you have a bad USB or something stuck in your micro USB port on the phone. Try a different USB and check the port on your phone. These are my first two instincts.

I had similar issues with my usb port. sometimes it would say charging even though it wasn't. I had to get a replacement phone, Verizon said it was a hardware issue with the port.

 

This is actually quite strange that you're having this issue too. I have nearly the exact same problem on my Gnex as well right after I had flashed liquid and than flashed another rom over it. I even returned to stock and locked the boot loader and still it wasn't fixed. But I do feel like this very well might be coincidence considering that I just figured that it was a hardware issue with my micro usb port.

 

I am having a similar problem. I have had my phone for three months and this just started a day or two ago. I have not installed any new ROMs. If I charge the phone using an old but higher quality cable that I have at work, I don't think I get the same problem. I just ordered some new OEM charging cables; but I'm not completely confident this will solve the problem since one of the chargers that may be causing the problem is the one that came with the phone.

 

I have a similar problem with a spare cable I use at work but mine is definitely an issue with that particular cable. I notice if I put some rearward pressure on the cable (while holding the phone with the screen facing me), it'll start to charge. So it's just an iffy connection. Make sure that's not the problem before exchanging the phone.

 

Had the same issue. The micro usb in the phone gets bent down. What I did was take a staple, and unbend it, then make kind of u shape. Stick it on the end of a paper clip with tape (the paper clip serves as a handle). Turn the phone off, remove battery, then hold the power button for 10 seconds to make sure the leads are totally discharged. Next, gently slide the staple under the port extrusion in the phone, and press up until you can easily slide the staple underneath with a hair of clearance. When my micro usb plug felt stiff to plug into the port, it was just about right. It still gets temperamental from time to time, but it's pretty much fixed. When I get back to my truck, I'll take a picture and edit the post so y'all can see what I'm talking about

 

Hello,

I had the same battery issue as the OP posted. However, currently it has been resolved since I am running Jelly Bean. When I had ICS AOKP B40, I had my phone over locked to its maximum and I assume the overclocking caused it (I was a newbie at that time). Currently, when I pulled out my charger from phone, it makes a minor squeaky sound. How is the warranty replacement with VZW and Samsung? Are we supposed to do paperwork since day 1 with Samsung?

 

If you bought your phone from VZW, your paperwork is basically your receipt and contract. They have everything documented from the purchase, so if anything needs to be done, they look it up via your phone number, and that's it. I'd try another charger if you can, just to see if it just might be the way that particular charger interacts with your phone, fit-wise.
