Remember that debacle over the LG G5 and HTC 10's support for Qualcomm's Quick Charge 3.0 and how it meant that those phones weren't exactly compliant with the USB Type-C spec? Google engineer Benson Leung actually opened our eyes to the issue and explained that by its mere mode of operation, QC 3.0 raises Vbus above the 5V spec limit to 9V and 12V to get faster charging rates.
Well, it looks like LG has done something interesting in its G5. It doesn't just support Quick Charge 3.0, but it also supports the official USB Power Delivery 2.0 protocol. Gtrusted's engineers did the test and showed the analyzer traces in the image above: the G5 can charge with Google's Universal Type-C 60W Charger at 15 Watts (5V @ 3A) and 18 Watts (9V @ 2A).
Googler Benson Leung chimed in with cautious excitement over the news. He says that this doesn't mean he recommends the phone, but that further investigation is needed to confirm the compliance of the G5 and to see how well everything works.
I'll let you check the sources to see for yourself if you understand this stuff better than I do. But at least today's news confirms that the G5 will indeed charge faster with Power Delivery 2.0 chargers.
