So... how it is with the charging, exactly? -- USB-C and wireless charging question

[ivorytasticspoon]

I am wondering about charging options for G7 and ask about two particular which I am most interested about.

1. Immediately when I got it I thought "cool, let's charge it a bit, let it sip a bit of a power from USB-C from the desktop", however there came the surprise No.1 - G7 is not fast charging, my 6P is (6P charges in 1 hour and something), G7 reported over 3 hours to charge.

How to fast charge the G7 from USB-C? I have a capable HW for that and Nexus 6P works that way.

2. I saw some mentions here that G7 supports 10W if not even 15W wireless charging, is that info verified? I am planning on buying a wireless charger (one at home, one at work), but I would like to know if there is pretty much any reason to buy 10 or even 15W chargers.

1. The desktop usually doesn't support fast charging. You need a phone charger that supports fast charging. The one included in the box will charge the phone for 1 and a half hours. You can of course buy a new one.

2. Any wireless charger will work but it won't charge fast. I tried Samsung's fast wireless charger but it charged the phone slowly. I would say, just use a cable if you're on a hurry and maybe a wireless charger when you're not using your phone.

But the thing is, Nexus 6P can, it is even stating it is fast charging via the very same USB-C port and cable, so naturally I am wondering why G7 is not.

Right now, G7 is being charged from USB-C just as long (considering what the estimation at the bottom of the screens is) I reckon would be charged via 5W wireless charger. I have dismissed the idea of more powerful charger, I don't need it, for that I don't mind it would be charging even over 3 hours.

And here's an example of how even though its a USB C port on the phone, not all features are implemented equally. Its either looking for some sort of resistance on the line in the cable or something else similar to that, as my Anker cables won't fast charge the G7 but will fast charge my Moto Z Play on my computer (which has the right port specs to support fast charge). If you look at the supplied cable with the G7, you'll notice that only one side of the C connector has contacts, and even then its a small amount of contacts that don't cover the whole side. more than likely the USB C cable you are using is fully built out so the phone is probably deciding that it won't quick charge when a fully spec'd C cable is used.

that's just my speculation

Nexus 6P doesn't support Qualcomm QC at all. LG G7 does.
Nexus 6P uses Quick Charge based on USB-C technology.
Different phones, different technology, different story.

Because Samsung wireless chargers use their own proprietary standard but not industry Qi which G7 is supported. G7 needs Qi capable fast wireless charging pad to enable 15W mode

Seems like Nexus 6P is capable of USB-C Power Delivery standard and G7 somehow is not. That's sad since I was hoping to buy one Anker or Aukey USB-C PD capable brick to charge G7 as fast as in can.

As for fast wireless chargers somebody should open a thread in https://forum.xda-developers.com/lg-g7-thinq/accessories about choosing fast wireless chargers. Like this one which is stated as supporting LG V30 with Qi EPP
