So far just about everything we’ve been seeing on the new Nexus smartphones has been pretty sweet, but now we’ve got some bittersweet news. It turns out that while the Nexus 5X and Nexus 6P do both support fast charging, they don’t use the standard Qualcomm Quick Charge 2.0 (or the newer 3.0). Rather they use a somewhat proprietary solution. Included in the box with both phones is a 5V/3A charger which you won’t find many other places. Most chargers come in around 2.1A or 2.4A at the highest, so rapid charging on the new Nexus phones probably won’t be easy without the original charging brick.
Droid Life put to test a handful of Quick Charge 2.0 chargers and found that a couple did register as “charging rapidly” on the phones, but it’s pretty hit and miss. So for now Google’s first party accessories (which are as of now sold out) will have to do. Undoubtedly there will be third-party accessories available in the near future, but for the first little while it’s going to be tough to take advantage of fast charge on this year’s Nexus devices.Source: Droid Life
