According to the product pages for the +Nexus 6P: https://store.google.com/product/nexus_6p and 5X: https://store.google.com/product/nexus_5x, both device conform to the USB-C standard instead of +Qualcomm QuickCharge 2.0.
On one side, it's great because it's a future-proof standard instead of a proprietary technology.
On the other side, +LG Electronics and +Huawei only ship a 5V charger.
Because the connector is of USB Type-C instead of Micro-USB, they pump up to 3A instead of 2A (QuickCharge 1.0 / Samsung) or 2.4A (Apple)
But 15W is less than to 9V / 2A (18W) or 12V / 1.8A (21.6W) from current QuickCharge 2.0 devices specs.
3A on 5V also means any long cable will waste energy, substantially less than 5V making it to the device depending on the cable quality and length.
Maybe these two phones will also accept 12V input as well (unlikely 20V) as it's part of the USB power spec.

That'll be up to the reviewers to determine and measure that.
Meanwhile, don't expect these phones to charge as fast as the current Motorola or Samsung generation.
As mentioned in the presentation today, they'll still charge a lot faster than the iPhones.

Interesting. While I'd prefer standard over proprietary, there is little argument that QC2.0 is a pretty great technology. Without it, I'm more hoping that the new Nexus devices are simply amazingly efficient.
I am looking forward to Doze on my Nexus 7 so hard it hurts. Being able to come back to a device after a few days with 1-2% off would be, without a doubt, incredible.
full charging in "half the time of the iphone 6+" means what? How long does it take to charge that behemoth?
+Dan Trevino iPhone 6(s) Plus are sold with a 5V / 1A (5W) charger, which is ridiculous.
They charge much faster with a 5V / 2.4A (12W) iPad one.

2.0 or 3.1 data rates?
+Adrián Calderón might be 3.0 data rates (need confirmation)
That's what the 810 and 808 support.
+François Simond did you order one?
+Jason Keiter I didn't consider buying one or the other: no money to spend on phones right now.
If I was, I would definitely wait for reviews and avoid the first batches (experience)
+François Simond It's USB 2.0, you probably know by now, but I will leave this here for others.
