Hello all, I just got my AT&T Version of the G4 this afternoon, plastic back one.
Observation #1:
When I opened the back to install the battery I see what looks just like a wireless charging coil with 2 contacts on the inside of the plastic cover. I don't really know if it is a wireless charging coil or not, I don't have one at home to test it, but it certainly looks like one. ( I'm out right now, I'll post a picture tomorrow and try it out on my wireless charger at work)

Observation #2:
I left the phone plugged in charging while I set up everything then turned off the phone, it was reading 98% on the screen while charging, plugged in and turned off. I went out to dinner, came back about 90 minutes later and it was reading 99% and the LED was still red. It is still reading 99% and the LED is still red. Don't know why it never fully charges, my other LG phones went to 100% and the LED went to either blue or green, depending on the model. Anyone else with an AT&T Version notice these 2 things?

I just got my ATT G4 and it charged up to 100% with no issue in about 90 min and the LED turned green.
 
Ok I unplugged the phone turned it on and off again put it on the charger and it went to 100% and light turned green.
Also while I was out I ran by my office and grabbed a Nokia wireless charger, and it doesn't charge, I wonder what the 2 copper contacts on the cover are for :/

Normally they are for the antenna on the back cover.

Thank you, that would make sense. I haven't pulled the back off of my one and only phone that has a removable battery in so long I totally forgot about the antenna connection.

As I understand it, that's the NFC antenna.
