[Nexus 6P General] BerryAl:
Of course. So.. the things in Bold are the tl;dr versions of everything.

Design

Some people have called the design of the Nexus 6P understated and some have called it a bit odd, mainly citing the unusual camera hump. But I think it's excellent. I ordered the colour that I liked the least (Silver) due to supply constraints and yet I still love it. It feels much better in the hand than any other 5.7"+ phone I've ever held, and the power button/volume rocker are placed perfectly, with the texture on the power button being an excellent touch to make sure you know what you're pressing. Coming from an HTC One M8, this phone has a lot of differences, mainly the overall size and button placement. The size was not as disruptive to the way I use my phone as I had expected it to be, and I love having a display this big.

Display

The display on this device is wonderful. Coming from a 5" Super LCD 1080p panel, there's some clear differences on paper and they clearly show themselves in real world use. Now, I especially have been clamouring over getting a phone with a large AMOLED panel but never wanted to get a Samsung device due to not particularly enjoying their design and/or software. Having used a PS Vita extensively, I've used OLED panels and have frequented PC World to try and convince myself to purchase a Tab S 8.4, but I somehow managed to stop myself. The panel on this phone is wonderful, I'm not able to accurately comment on colour accuracy, nor the RGB range, etc. But I can tell you that this display gets bright enough for me to see it clearly in sunlight (though no brighter than the bare minimum for bright sunlight), it has wonderful colours, brilliantly deep blacks and just generally feels wonderful to use. The resolution here I feel is less important; 1440p clearly trumps 1080p, but the difference in real world use isn't that noticeable, so it needs not much comment. Everything looks as sharp as you could hope.

Battery

This device clearly has a pretty large battery, and with Marshmallow you would expect some pretty excellent battery life here. Well, as far as I'm aware, this thing delivers on that promise and delivers it well. First off, Doze is excellent, you can clearly see its application when the graphs gradient reduces to being practically flat. The screen I'm sure is also good for conserving battery as this uses a latest generation sammy panel, who's devices are known for getting pretty decent battery life out of relatively small battery sizes. As i have shown on the battery life thread, I got just over 5 hours of screen on time over the course of a day that was about 20 hours long. This included some light PDF usage, internet browsing, lots of messenger, some youtube videos, a pretty standard kind of day really. I was connected to WiFi for about 90% of my day and didn't use mobile data very often at all, so this will certainly be different for a lot of people depending on the way they spend their days. This battery far surpasses my HTC One M8 and the charging is also very quick. Left it on charge after posting those screenshots for just an hour and it went from 11% to 87%, so pretty much ready for another day's use. If an hour is all I need to charge up for the whole day, then the charging is certainly quick enough for me.

Software

Marshmallow, to me, is like Lollipop with better performance and better battery life. I couldn't care much less about Now On Tap, nor for most of the other minor changes, besides those which help battery life and performance. Because, well, this version of Android is pretty similar to 5.0, it should have been 5.2 as far as I'm concerned, but I guess a totally new version helps to make the new Nexus devices appear more ahead of the curve than they really are. Doze is excellent, camera app is improved, everything else is excellent as it should be. Good job, Google.

Camera

The camera on my One M8 was a mess, and it's the main reason for me upgrading a year before I was planning to. The camera on the Nexus 6P is good, it isn't as good as the Note 5, iPhone 6S Plus or the LG G4 (in my opinion) andI think that DxO were more generous than they should have been. It also would have helped to have OIS, regardless of the pixel size blah blah blah. This camera is enjoyable to use, takes good pictures, and is quick to boot. The double pressing the power button to launch works well and very fast, though not as fast as sammy's alternatives, you shouldn't be missing any photo-opportunities here. Low light photos are good, but to be honest the camera is the area where my technology knowledge most falls flat, so I'll leave this to others to comment on mostly.

Performance

Incredibly fast. That's about all there is to it. Heat isn't an issue, but watching 1080p60 videos on YouTube can cause it to get very warm, like most any other device really, as will the usual intensive tasks, 4k video etc. etc.

This thing is quick as it should be and the 810 needn't be an issue for anyone. Throttling is not something I think I'd ever need to worry about with my usage I think, but if it is present then it certainly does not affect normal daily usage.

Fingerprint Scanner

Quick, very very very accurate, will very rarely read my finger wrong, and reasonably well placed. I think that one on the front would have been more convenient at times, but this placement is convenient for more times; I don't think that there is a perfect placement for a finger print scanner and there will always be times when it's in annoying position/orientation to use. But I do like it and enjoy using it, when usually I wouldn't bother with ANY security on my phone, now it is so convenient that there's no reason not to.

Conclusion

What needs to be highlighted here is the excellent coupling of hardware and software. The Nexus line is no longer held back by design, camera or battery life. Google can now show off the best of their best with the Nexus 6P. This is a great device and I love using it. Those on a Note 5 should have no reason to switch, but anyone on a Nexus 6 should definitely be considering it. Huawei have also just created a device that can show the world that they are a serious contender in ANY market. I would recommend this phone to anyone, but just remember that 5.7" is never going to be a small phone, and one handed use takes a hit here, but it feels like an easy adjustment to me. This phone packs everything you could want, and that's what makes it so appealing, that it just doesn't seem to fall down in any particular area. I've long thought about why no one had just made an Android phone that did everything well, and now Google and Huawei have shown that it can be done, and hopefully this can raise the bar for all Android phones to come.
