The specs say that the LG V 60 is Qualcomm 4+ certified. Does the phone use a 4+ charger and charge faster than with a QC 3 charger? I ask because my LG V40 is also certified QC 4+ compatible, but LG didn't activate the 4+ ability so using a 4+ charger doesn't charge any faster than a QC 3 charger. Thanks in advance,
