Sad as it may be, if you've been hearing that the G4 has wireless charging right out of its shiny new box, unfortunately that just isn't true. LG went on the record with us to state that no version of the G4 will be shipping with wireless charging as a standard feature, and that you'll need to buy one of the company's Quick Circle covers if you want to get your battery those sweet, sweet electrons via induction. Here are the specifics.
Almost every G4 sold around the world will support Qi wireless charging - once you buy the Quick Circle case. This is just the same as things were with the G3 last year. The only version of the G4 with PMA charging is the one AT&T will sell here in the United States.
The AT&T G4 will require an AT&T-specific Quick Circle case that supports the PMA standard. The AT&T version does not appear to support Qi charging. It also appears unlikely that AT&T's G4 will be able to use the Qi-enabled Quick Circle cases from other carriers or retailers here in the US, though we were unable to get a full confirmation of this.
In addition, LG has stated that the Quick Circle case is available only in the rubberized / plastic finishes. So if you buy a leather back G4, you will have to go back to plastic if you want to charge wirelessly (the Quick Circle case replaces the stock rear cover).
As far as we know, there is no model of the G4 that will support both PMA and Qi, so if you've been seeing that anywhere, consider it provisionally debunked. If you buy a G4 here in America, all four carriers will support wireless charging, you'll just have to throw more money at them (or someone else selling the cases) to get it. And if you're on AT&T, that probably is going to mean paying full retail MSRP for the case unless you're patient enough to wait out third party retailers.
At least there's Quick Charge 2.0! Which is miles faster than Qi anyway.
