However, the P could've stood for ... a lot of things: 'Plus', since it requires two hands to operate the phone properly, or 'Palmable', as it's still way easier to clutch in one hand than the 6-inch Nexus 6.
It could also have easily stood for 'Photos', considering the Nexus 6P camera benefits from a 12.3-megapixel (MP) sensor that does a better job than many other cameras in low light; 'Power', as the device uses USB-C for fast charging; or 'Performance', given the top-of-the-line specs and inclusion of Android 6.0 Marshmallow.
Finally, the 'P' should be popular among bargain hunters for its 'Price'. When it launched the 6P had a starting price of US$499 (£449, AU$899) for the 32GB model, making it less expensive than the Google Nexus 6, which went for US$650 (£500, AU$870).
If you fancy a bit more space the 64GB version will set you back US$549 (£499, around AU$999), while the 128GB comes in at US$649 (£579, around AU$1099).
Since launch though, prices have come down slightly, and you can now pick up a 32GB SIM-free Nexus 6P for around £430 in the UK if you're willing to shop around.
All of that said, there seems to be an endless number of 5.3- and 5.7-inch phones vying for the same phablet audience: iPhone 6S Plus, LG G5, Samsung Galaxy Note 5 and Moto X Style.
While the Nexus 6P price is down, the specs have been upped just enough to make this a cost-effective Android contender for our best phones list.
Huawei built the Nexus 6P to be different to any other Google-commissioned phone. Its metal design is undoubtedly a step up from the plastic Nexus 5X, and every previous Nexus.
Although relatively flat around the back with barely tapered edges, it feels comfortable in one hand, yet it still takes two hands to operate it properly. This is, after all, a phone with a 5.7-inch display.
Its dimensions are 159.4 x 77.8 x 7.3mm, making it just one tenth of a millimeter taller than the Nexus 6, but notably narrower and thinner than its predecessors measurements of 159.3 x 83 x 10.1mm. My overly stretched-out, phone-wielding hands appreciate this change.
It went on a much-needed diet to become palmable, weighing in at 178g compared to 184g a year prior, despite Huawei raising the bar on the Nexus 6P specs.
Clearly, it was hard to fit everything in. The 12.3MP camera creates an unsightly-looking rear bulge with a black strip, but this eyesore is a fair trade-off given the better low light photos.
Everything else has a luxurious look to it. There's a riveted power button with a unique texture, and a smooth volume rocker, on the right side of the frame. There's little chance of mixing up these buttons in the dark.
Since arriving on the scene though, we've seen a flurry of new flagship phones sporting similarly impressive premium bodies including the Huawei P9, HTC 10 and Samsung Galaxy S7 - all of which are also easier to grasp with a hand. Of course, their screens are also smaller, so you'll need to decide how big you want to go.
There's also no chance that I'll ever put the charging cable in the wrong way. A reversible USB-C port sits on the bottom of the frame, replacing micro USB for faster charging.
While a 3.5mm headphone jack rests at the top, I dig the front-facing stereo speakers enough to use them. Too many Androids put the speakers on the back, which makes no sense at all.
There's no off-beat color here, in a year when the Nexus 5X has a minty-looking Ice Blue color and the iPhone 6S debuted a popular rose gold option.
The Nexus 6P colors keep it simple with Aluminium (gray), Graphite (black) and Frost (white), although at CES 2016 manufacturer Huawei launched the gold variant of the 6P.
Want to customize or protect it? Google has already rolled out multiple cases. I tried out the microfiber 6P case and the very rubber 5X case, and prefer the microfiber option hands down. A leather folio case and elastomer are also options in the Google Store.
Display, fingerprint sensor and USB-C
The Nexus 6P challenges the Samsung Galaxy Note 5 and Moto X Style with a 5.7-inch display and quad HD resolution, and it keeps pace with its fellow Android juggernauts.
That's because it's backed by similar technology – a 5.7-inch AMOLED display, which contrasts with the 5.2-inch IPS LCD found in the Nexus 5X, LG G4 and iPhone 6S.
The screen has a 2,560 x 1,440 resolution with a dense 518 pixels per inch, and, all around it looks brighter and more colorful than the Nexus 6, which also had a dimmer quad HD display at the same resolution.
Brightness is undoubtedly higher when "adaptive brightness" is turned off, and color accuracy is a step in the right direction compared to what we saw from its predecessor.
Without diving into the developer settings, the screen is still more saturated than true-to-life. That works for some subjects, like vibrant-looking red strawberries, but looks unnatural on an actor with a slight tan.
The Nexus 6P retains the Adaptive Display functionality from Motorola's Nexus 6. Whenever the phone is picked up or a notification arrives, it flashes a grayscale notification lockscreen.
I prefer the gesture-sensing Moto Display, which uses tiny IR sensors embedded in the front of the phone to detect motion or a hand wave and then display the time and peekable notifications.
The screen also doesn't have the common double-tap-to-wake function found on the LG G4 and HTC One M9. That would've helped, given the rear-facing fingerprint sensor.
The Nexus 6P's aluminum unibody doesn't attract fingerprints like the smudge-filled Nexus 5 in black with its soft-touch coating. But it does have one spot where fingerprints are wholly acceptable.
Google's Nexus Imprint Sensor is introduced in the Nexus 6P and Nexus 5X, and it works a lot like other biometric fingerprint sensors out there, including Apple's Touch ID home button.
There are two key differences. Registering a new fingerprint takes no longer than eight seconds, whereas Apple and Samsung's methods require too many long presses and pauses.
More strikingly, the fingerprint sensor is on the back and static – it doesn't double as a button that you can press down. Google's hypes this spot as a natural location for your fingers.
My index finger, usually resting along the frame, disagreed at first. I had to learn to bend it around back to unlock the phone, and it was initially awkward, but I eventually got used to it.
It's a little easier to pull off on the smaller Nexus 5X, but the tradeoff is that I didn't smudge the Nexus 6P camera, which is off-center and further away than on the 5X.
On either phone, it takes half a second to unlock the phone and, even with the fast setup time, the sensor is just as accurate as Apple's and Samsung's.
However, I still find myself using archaic unlock methods, simply because it's easier than picking up this 5.7-inch phone whenever it's resting on my desk or a table.
This is where front-facing fingerprint sensors work best. However, between you and me, I find that the Nexus 6P is ideal when 'talking' to someone, but really nonchalantly unlocking my phone in back. Sneaky, sneaky.
Google's Nexus design evolution is reflected in more than just the matte aluminum build. The Nexus 6P makes the jump to charging and transferring data via USB-C.
This means your stash of micro USB cables is useless, and you'll have to tout around this new connector and charging block. Forget it – or worse, lose it – and your phone's battery life is in jeopardy.
Changes like this are always a bit jarring, and I feel like I have too many cables already. Every other Android phone and tablet I have uses micro USB, and my Apple devices use Lightning.
My Apple Watch and Android Wear smartwatches take advantage of multiple inductive chargers, and a few holdouts like GoPro still require a USB mini. My bag is full of chargers, and this is just one more.
But, once everyone gets on the same page, the advantage is clear: USB-C offers faster charging times, and the connector is reversible – I never fumble around with inserting it into the Nexus 6P.
Google at least made the transition easier. The Nexus 6P comes with a USB-C-to-USB cable, so you can still charge and transfer files into a computer with normal USB-A port. The Nexus 5X doesn't offer the same accessory for free.
Specs and performance
The Nexus 6P has been built to be a cutting-edge phone, and it succeeds with more advanced architecture than the Nexus 5X and several top Android phones.
This is because it harnesses the power of the Snapdragon 810 v2.1, which doesn't run as slow or hot under pressure as the Snapdragon 810 when it debuted in the LG G Flex 2.
Qualcomm's 64-bit, octa-core processor combines a faster 2.0GHz quad-core chip and a slower, but more energy efficient, 1.55GHz quad-core one. The results finally strike the right balance.
Saving even more power, the Nexus 6P includes what Google calls the Android Sensor Hub, a dedicated motion chip that alone drives all sensors on the phone. This leaves the core processing unit more bandwidth (and thus power) to run the operating system.
The Android Sensor Hub accomplishes orientation and motion tracking tasks, all without taxing the processor. It goes hand-in-hand with the battery-saving, Android Marshmallow Doze feature.
There's an Adreno 430 GPU embedded into this System on a Chip, or SoC, too and, more importantly, 3GB of RAM. The hardware is fit for multitasking through a whole bunch of apps without much slowdown.
It's exactly what I hoped for, given the souped-up specs, but bargain price compared to top tier phones from Apple and Samsung. It's definitely a step up from the Nexus 5X (2,990).
There was an off-chance that the Snapdragon 810 v2.1 processor wouldn't be the fix Google and Huawei were hoping for. While there's some slowdown, it's not the dramatic trouble that made the LG G Flex 2 so disappointing 9 months ago.
Android 6.0 Marshmallow and apps
Google and Huawei's Nexus 6P's refinements apply mostly to the hardware, but are also found in its software, with the Android Marshmallow operating system pre-loaded onto the phone. Now at Android 6.0.1 as of January 2016, it's a smoother experience from boot up to battery drain.
There are actually few obvious changes. It's mostly behind-the-scenes adjustments, like longer battery life when the phone is on standby and app permission tweaks.
Android 6.0 Marshmallow makes for a smarter version of Google's mobile operating system, and that's ingrained in its one noticeable, front-facing feature, Google Now on Tap.
Holding down on the on-screen home buttons brings up Google Now on Tap, which scans what you're currently reading, watching or hearing, and it tries to educate you on the topic.
Reading about the new Star Wars movie poster in the news and holding down the home button instantly brought up a short description and series of links for both Star Wars and Lucasfilm.
They're in the form of icons, but lead to Star Wars-appropriate Google searches, Wikipedia entries, social media content and Google Play Store apps. It's a neat shortcut for more information on whatever you're currently looking at.
This works best in messaging apps, wherein someone references a show, actor or newsmaker you know nothing about. Google Now on Tap is a simple way to cross-reference the internet.
Everything else about Android Marshmallow is straightforward in that Nexus 6P is a phone with stock Android. It really contrasts with the two dozen worthless apps, say, Asus phones levy on you.
It's filled with your favorite Google apps out-of-the-box instead: Gmail, Google Maps, Contacts, Drive, Calendar, Photos, Hangouts, YouTube, Photos and so on.
Pinned to the home screen are Google's camera, SMS Messenger and Play multimedia apps in a folder. Inside is Play Music, Play Movies & TV and Play Games.
The Google Play Store acts as your portal to downloading everything else, from Facebook and Instagram to LastPass and Pandora.
The last thing I'll touch on before getting into specific apps is the all-encompassing app drawer. Prepare your brain, since it now has you scroll up and down (no longer left to right). There's a handy recently used apps row at the very top to take away some of the pain.
If you fancy getting an insight into the future of Android you can download the beta version of Android N onto your Nexus 6P right now, for free.
Google's made it super easy to install, just head to android.com/beta on your 6P and follow the instructions on screen.
A word of warning though – this is a beta build of Android N, and thus it won't work perfectly. I've been running N on my 6P for over a week and on the whole it works well. I do find a few apps don't work (BBC Sport and NFL Mobile are a couple of key examples) – so be prepared to be without some of your favorites – but the majority run without issue.
I haven't witnessed any battery improvements thanks to the improved Doze mode, but again the software is yet to be optimised so hopefully it will be more noticeable come the find build.
I've never been a big fan of messaging on Android, because so many of my contacts use different apps. Nothing ties them together, and the Nexus 6P software doesn't fix this.
It does, however, offer a clean and simple SMS app called Messenger (different from Facebook's identically named Messenger app). It's fast and lightweight.
Google, of course, still packs in Hangouts, which was redesigned over the summer for both iOS and then Android. It's better, but can't really top Apple's iMessages way of doing things.
As I explained in my Nexus 5X review, text messages are isolated on my Nexus 6P when using the Messenger app, and Hangouts confuses people by integrating my work email or my Google Voice number.
Group messaging with a number of iPhone users is also a problem (this one problem isn't necessarily Google's fault). My messages go to the original messenger and no one else.
It's a shame, because Google has a fantastic keyboard by default, with finger swiping enabled on the frontend and a smarter autocorrect system in the backend.
Movies and music
The 5.7-inch display of the Nexus 6P is a better fit for watching HD movies in a 16:9 aspect ratio when compared to the old Nexus 5.
The screen size isn't as big as the 6-inch Nexus 6, but the color is more accurate. I don't find the hues to be overly saturated, though some people may find this to look washed out.
Really, you can see the difference in side-by-side comparisons of actor's faces. Orange is the new tan, when I watched "Big" on the Nexus 6P compared to the Nexus 5X.
The latter doesn't have the artificial pop of the Nexus 6P and doesn't boast that quad HD display, but it's colors are more true to life. Nexus 6P, however, beats the 5X when it comes to sound quality.
Listening to music and movies is a bit one-sided on the Nexus 5X. The speaker for all media is located in the bottom of the phone, whereas the multimedia-friendly Nexus 6P has stereo speakers at the top and bottom.
The Nexus 6P can handle all of the game apps I throw at it, with no discernible slowdown or imperfections in the graphics and color. Real Racing 3 and Asphalt 8: Airborne get along just fine.
Slight variations between Nexus displays favor the Nexus 5X when it came to movies starring real people, but game apps I test look, oddly, a tad more muted in color on the 6P display.
Bezel has become a bad word among smartphones, but I find games in landscape mode easier to control, thanks to the slightly thicker bezel of the Nexus 6P (the same is true of the Nexus 5X).
The Nexus 6P camera, along with the Nexus 5X, is the best of any Nexus phone, Google said to no one's surprise. After all, we only saw subpar results from the Nexus 5 and Nexus 6.
What's different here is that the 12.3MP Nexus 6P rear camera captures 1.55-micron pixels, which is larger than the normal 1.4 microns. Translation? Bigger pixels and more light captured.
This allows me to take superior indoor photos, especially in low-light situations like restaurants, bars and outdoors after dark. I'm pleased with the results compared to older Nexus phones.
It's also identical to the 12.3MP Nexus 5X camera sensor, save for processing speeds. I had to double check the files when comparing my photos to make sure I didn't load the same ones.
Both new Nexus phones lack optical image stabilization (OIS) and the nifty camera software that is offered by Samsung and LG.
You won't find options to shoot in RAW, gesture controls to snap selfies without touching the display or software-manipulated wide selfies for group shots.
Google, to its credit, has improved its default camera software in a year's time. You can switch between the front- and rear-facing camera with just one tap instead of two confusing taps.
You can also set the timer with one press, too, and turn on video recording with an easy swipe. This Nexus 6P camera records video in 4K at 30 frames per second, while the front-facing camera is 8MP with the normal 1.4 microns and the same f/2.0 aperture.
In fact, the only thing hidden in a side menu are returning modes: Lens Blur, Panoramic and Photosphere.
This is where Google's camera failed to impress me more than Samsung's Galaxy Note 5, as much as I saw impressive results from both. The extra modes and post-production processing found in recent Samsung phones is still top-notch, even with the normal 1.4 microns.
The Nexus 6P is a big phone with a big battery. At 3,450mAh, it's capacity is bigger than most other phones we've reviewed, save for a few, like the Samsung Galaxy S6 Active and Moto X Play.
Google's phablet lasts slightly longer than one day with heavy use, so you'll have time to get back to that all-important USB-C charger before it's completely drained. It lasts just long enough.
Our battery life tests indicate that how quickly the battery drains heavily depends on the display settings you have the phone set to: for example, is adaptive brightness on or off?
Turning it on saves battery life, with our 90-minute HD video running the 100% charge down to 84%. That's just shy of the Samsung Galaxy Note 5 that ran down to 86% at full brightness.
However, this isn't the true full brightness of the Nexus 6P. Diving into the settings menu and switching adaptive brightness off drains the full battery life down to a less impressive 75%.
What helps, if you're not constantly turning on the display, are Google's new software tricks: Doze mode and App Standby. They essentially put the phone into a semi-sleep mode.
When you go to pick up your phone after waking up, and it wasn't on the charger, you should see minimal battery drain and breathe a sigh of relief. It's a handy tool, and beats the pants off of straight battery life tests.
Even better, when you do charge the Nexus 6P, it takes just 1 hour and 37 minutes to juice the battery up to 100%. That's faster than the Nexus 5X and it's smaller and weaker battery.
It's marginally slower to charge than Samsung's Fast Charging and Qualcomm's Quick Charge 2.0 standards, which use a micro USB cable along with a larger-than-normal charging brick.
Samsung's Galaxy S6 and Note 5, for example, fill back up in 1 hour and 20 minutes. Thus, USB-C is nearly as fast with the added benefit of being reversible.
What's missing here are any sort of wireless charging capabilities. Samsung's phones are leading the way via their 88-minute "Fast Charge Wireless Charging Pad."
Google, on the other hand, didn't include any sort of wireless charging in its two Nexus phones. It recently yanked the Nexus Wireless Charger in its Google Store because of this reason.
Samsung Galaxy S6 Edge+/Galaxy S7 Edge
Samsung is an old hand at phablets, so it's no surprise that the Samsung Galaxy S6 Edge+ and newer - and slightly smaller - Samsung Galaxy S7 Edge present the Nexus 6P with some stiff competition.
The name might be a bit of a mouthful and with a 5.7-inch screen the S6 Edge+ is too, but what a screen it is. Like the Nexus 6P it's QHD, but unlike the 6P it's also curved, leaving it looking absolutely gorgeous.
Sadly, those curves are little more than eye candy and the S6 Edge+ is pricier than the Nexus 6P, but with a stylish metal and glass build, a class-leading 16MP snapper, a powerful octa-core processor, 4G of RAM and a fingerprint scanner it goes a long way towards justifying its price tag.
It's more powerful and more stylish than the Nexus 6P and it also has better photographic chops, but with underwhelming battery life, a high price and a more cluttered take on Android than the 6P's stock offering it won't be a better buy for everyone.
Meanwhile the Galaxy S7 Edge offers up a more palm-friendly 5.5-inch dual-curved display in a far more compact body and even more power stuffed under the hood. It'll cost you an arm and a leg though.
The iPhone 6S Plus is Apple's second stab at a phablet and it's quite an achievement. It's actually barely a phablet by Android standards, and certainly smaller than the Nexus 6P at 5.5 inches. At 1080 x 1920 it's also not as sharp, but it's bright, clear and vibrant, so you probably won't miss the extra pixels too much.
It also sports 3D Touch, which hasn't reached its full potential yet, but is still an exciting new way to interact with the phone.
With a decent camera, a premium design and slick performance too the iPhone 6S Plus doesn't feel particularly lacking in any area. But it's a lot more expensive than the Nexus 6P and if you want a true phablet it's a little on the small side.
The Moto X Style is another 5.7-incher with a QHD screen and like the Nexus 6P it's fairly affordable for a flagship.
It's got a lot going for it too, with strong performance, a bright and vibrant screen, a good camera, powerful speakers and Moto Maker customisations, allowing you to create a good looking handset that fits your own style.
Like many recent smartphones the battery life is a bit on the low side and at 11.1mm thick it's a little chunky. But otherwise it's a strong and stylish alternative to the Nexus 6P and with near stock Android on board the interface is pretty similar to Google and Huawei's latest offering too.
The Nexus 6P is one of the best Android phones you can buy right now, given its top-of-the-line specs for a more affordable price. It's easier to hold and takes better photos.
That wasn't a big surprise to me in this review. This phone was always going to be better than the Nexus 6, as much fun as I had with the ridiculously big screen. Where the 6P fits into the current crop of Android phones remains the biggest question over my week of testing it out.
I can hold the Nexus 6P in one hand without dropping it, although it takes two hands to operate. That's a relief for anyone who couldn't adjust to the Nexus 6. The back of the phone has a fast and accurate fingerprint sensor and the front fits in loud-sounding stereo speakers.
It has Android Marshmallow 6.0, which is worthwhile simply for its battery-saving tricks. The best part is that you get all of these features and a fast processor for a lower-than-average price. For these reasons, this is the best Nexus phone and one of the best Android phones right now.
That said, this phone is not for everyone. There are more full-featured phones out there from familiar names, like Samsung and LG. The Nexus 6P's hardware isn't as fast as those rivals' flagship phones, and it's missing a few of their best camera software tricks.
There's no wireless charging or optical image stabilization integrated into this phone. These are two things that are becoming standard among the best smartphones. Really, though the biggest problem for this new Nexus phablet is that there's so much competition.
The Nexus 6P is a luxury phone without the premium price to match. Behind its aluminum finish are powerful phone specs that nearly keep up with Apple and Samsung's flagship phablets. That's because the Snapdragon 810 v2.1 processor gives Qualcomm's troubled chip new life, plus 3GB of RAM is just enough to future-proof the phone.
As for USB-C… it may be ahead of its time. Consider yourself an early adopter when it comes to this and Android Marshmallow. The Nexus Imprint fingerprint sensor is right on time, even if it landed on the back of the phone, and Google finally catches up to Apple's Touch ID. This method offers just as much speed and accuracy.
Google's super-sized phone is thinner, lighter, stronger and easier to hold, making it a true step up from the Nexus 6 in every way imaginable. No, it's not fast as the Samsung Galaxy Note 5 and Galaxy S6 Edge+ – and the 12.3MP camera is comparable, not always better. But this is the best phablet for the price, hands down, and returns the Nexus brand to its more affordable and palmable roots.
