Here's the text of a chat I just had with AT&T, which seems to confirm that (a) the H810 won't work with Qi chargers, and (b) AT&T chatters are clueless on this matter:

Your chat transcript:
Jessica : Welcome to AT&T Chat. How may we help you today?
Me : I just bought a LG G4 H810 to use with my ATT account. I find that the circle-case charger I also bought doesn't work on a Qi charger. Is there any wireless charger for the H810 that does work with Qi? Wireless charging is a must-have for me, and I would rather not have to return this phone and/or find a different carrier.
Jessica : Ken, in this moment we have the Belkin Wireless Charging Pad
Jessica : I was checking, and this wireless charger is able to work with all the LG series
Jessica : I can send you the link in order to check it
Me : Yes, please.
Me : But I'm also asking whether there is any wireless charging antenna that i can attach to the H810 that will work with the many charging stands I already have that use the Qi standard? (Rather than the PMA standard.)
Jessica : ok, I see
Jessica : Ken, I can connect you with our specialist department
...
Steve : Hi Ken! This is Steve. I will be happy to assist you today.
Me : Hi Steve. Have you read the chat so far?
Steve : I was. Let's look at those charging options that LG has.
Steve : While it seems that circle charger does seem to be the most prominent Qi charger available, I see mentions of a rigged case that was being used.
Me : I have a circle case that includes the Qi antenna. It works OK on a LG G4 H811 that I had, but when I put the same case onto my LG G4 model 810 (the only one that works with ATT as a carrier) it doesn't work.
Steve : There are replacement stickers that may help with that case to charger connection. I was looking at some references to cases out of the UK in the Android forums, but no one is saying which case.
Steve : You can reach out to LG at 800-793-8896 or
LG: Mobile Devices, Home Entertainment & Appliances | LG USA to see if they may have some additional recommendations.
Me : There are sticker-antennas you can get that go inside the LGG4 case. But the talk on the forums (
http://forums.androidcentral.com/lg-g4/532670-t-variant-wireless-charging-pma-again-qi.html) is that NO Qi antenna will work with the ATT model of LGG4. I'm entering this chat in hopes that that is not true, but I think it's confirming that it is true. Right?
Me : If so I would appreciate your passing on to the ATT powers-that-be that this is a dumb thing for them to be doing to their customers. None of your competitors are doing it. See the above forum thread for more.
Steve : We do not support the wireless charging with that device. These devices may be capable though. With that charging, we would suggest contacting LG.
Me : Well, I guess that's as far as I can go with this chat. Thank you for the try.
