The LG G4 does things a bit differently from the rest of its Android flagship competition, and in contrast to both the Samsung Galaxy S6 and HTC One M9, the G4 elected to give users the flexibility of a removable battery. By popping off the phone’s rear shell and swapping out the 3000 mAh component within, you can instantly go from a handset that’s about to die to one that’s ready to keep running all night long. That’s well and good if you’ve got a spare battery lying around, but it sure looked like this one battery feature was coming at the expense of another: unlike the GS6 or M9, the G4 didn’t arrive with claims of support for any fast charging technology. As it turns out, that’s just because it’s something LG chose not to emphasize, and the G4 very much supports Qualcomm’s Snapdragon Quick Charge 2.0 system.
As LG explains to us, while the company didn’t specifically engineer the G4 with the intent of it supporting Quick Charge, the system is built in to the phone’s Snapdragon 808 SoC in such a way that it’s fully functional in the finished G4.
While the power adapter the G4 ships with isn’t a Quick Charge-compatible unit, if you pair the phone with a suitable third-party Quick Charge 2.0 adapter, the G4 should be more than capable of taking advantage of its fast-charging tech.
We’re in the process of doing a battery test on our own G4 to verify that, but this news comes straight from LG itself, so consider it official. As LG puts it, “at the end of the day, we see Quick Charge as a nice-to-have, not a must-have, since we offer a replacement battery. This is what we’ll continue to focus on.”
Update: Our tests with an LG G4 and a Quick Charge 2.0 charger appear to confirm the manufacturer’s assertion. From a fully discharged handset, we hit 16% battery charge in just 12 minutes, and 25% in 19 minutes.
