This is why the Nexus 6P and 5X don�t have Qi Wireless Charging

It�s nearly impossible to design a tech product that won�t generate some reason for complaints from some cross-section of consumers. Make the world�s thinnest device and people complain about specs. Make the most powerful device on the planet with amazing battery life and people complain its too bulky. Everything is a balance, but one particular omission from the newly announced Nexus 6P and Nexus 5X are drawing a lot of complaints: there is no Wireless Charging.

Now we know why Google didn�t include Qi Wireless charging in these new devices:
We added Qi wireless charging starting with N4 because plugging in USB micro B was such a hassle! (Which way is up!?) With this year�s Nexii, we support USB Type-C which has a reversible connector so there�s no more guessing. AND it charges incredibly swiftly: 1% to 100% in 97 mins on the 6P for example (the first ~45 mins of charging is especially fast). Meanwhile, wireless charging adds z (thickness). So, ease of plugging in + fast charging + optimizing for thinness made us double down on Type-C instead of wireless!

We won�t agree or disagree with the question, because it all comes down to personal preference, and that�s part of Android�s beauty- if you don�t like it there are dozens of other amazing Android phones from which to choose. We will say, however, that we hope the next generation of wireless charging comes soon.
