Google's trying to push its design forward, and to champion new ideas about the way the future should work. It's still trying to make a crazy-powerful phone, too. The 6P is powered by the Snapdragon 810 processor, still the cutting-edge in smartphone chips—it has a tendency to run a little hot, and so does the 6P, but it's nothing to worry about. There's also 3 gigs of RAM, and between 32 and 128 gigs of storage. That's all nice, but it's also table-stakes for a device like this one.
The 3,450mAh battery inside is more than enough to last through a day, but not any more than that. It has a USB Type-C charger, which is good and bad. It's hard to find accessories and cables to replace yours. But on the flip side, holy hell does this thing charge fast. Twenty minutes on the charger, and you're good to go for the evening. Until we get truly ground-breaking battery improvement, ultra-fast charging will have to do.
Lens Is More
Where Google really went above and beyond was the camera. Nexus cameras traditionally have fallen somewhere between bad and worse—not where things should be for what is, to most users, the single most important feature. The Nexus 6P (and 5X) went all-in on the camera. It has a 12.3 megapixel sensor, which is big; its pixels are 1.55 microns each, which also is big. The combination of the two is huge. Using this camera forced Google to design its phones around it—the hump on the 5X, the stripe on the 6P—and make it the centerpiece of the whole experience.
Good thing, too. The Nexus 6P is one of the best smartphone cameras I've ever used. At points, I'd have called it the best, but the truth is it's ascended into the space where all that matters is personal preference. I like the slightly saturated colors; you might prefer the iPhone's more muted look, or the slight brightening you get from the Galaxy S6 Edge. That's all fine! What matters is the 6P, like those other phones, takes excellent pictures.
If you read its spec sheet, the 6P sounds like it might be particularly great in low light—those big pixels take in more light, which means shorter shutter speeds, which means sharper pictures at night. That's true, a little, I guess, but not really. For the most part, this camera shoots like every other camera in bad lighting. Which is to say, not well. Sometimes it over-brightens shots, or takes street lights and blows them up to look like an alien spacecraft shining light from above. Sometimes it just over-processes and softens all your photos. It's still among the best low-light smartphone cameras, but it's not reinventing any wheels here.
The app doesn't really help the cause. It's simple and easy to figure out, even when you're doing crazy things like shooting Photo Spheres, but the app is just slow. Weirdly slow for such a fast phone. Focusing takes a little longer than it should (especially when the flash is on), and there's basically nothing in the way of manual controls. It's a decent starting point but you'll quickly want a more advanced app.
It's Not About the Hardware
Don't lose sight of the big point here, though. Google and Huawei made a phone that has exactly zero problems. It's well-made, it's fast, it has a great camera, it has great software. The Nexus line has always existed to show the best Google can do. For the first time, maybe ever, this feels like it.
There's only one problem: Google doesn't control everything. Where the 6P falls short of a competitor like the iPhone is in all those other parts. The apps are the most important one. No matter the number of apps in the Play Store, it's hard to deny that the iPhone's apps are almost universally of a higher quality. Android apps don't work the same way—some use the back button one way, others another, some have their own back button, some I'm still not sure. They don't look as good, or work as well. Apple's fanaticism over its human interface guidelines may feel dictatorial, but it makes the iOS experience much better. Add in the constant security issues with Android that just don't plague the iPhone, the difference in customer service between Apple's Geniuses and basically everyone else, and there are just too many holes.
The Nexus 6P is absolutely the best Nexus phone ever. Hell, it's the best Android phone ever. And at $499 unlocked, it's even cheaper than nearly all its competitors. Everything Google could do, it did. It proved how good Android can be—that an Android phone can be better than the iPhone. Now it needs a few developers to pick this thing up, and build something worthy of the smartphone of the future.
