The Google Nexus 6P Review
by Andrei Frumusanu on December 16, 2015 8:00 AM ESTSystem & CPU Performance
The Nexus 6P comes with a Snapdragon 810 designed by Qualcomm. This is a big.LITTLE 4x A53 @ 1.55GHz + 4x A57 @ 1.95GHz SoC. As we’ve hopefully come to be very familiar with the chipset over the last couple of months, the key characteristics with which the 6P can differentiate itself from other Snapdragon 810 devices is through software optimizations. In particular the fact that the Nexus 6P comes with Android 6.0 Marshmallow should allow it to be able to showcase some improvements which we’ll dive into a bit later.
First we start by comparing performance of some of our browser-based benchmarks. These are predominantly Javascript tests which require large single-core performance out of the device’s SoCs.
In Kraken the Nexus 6P is able to showcase a very good score that’s only beat by, oddly enough, the LG G4. As we’ve come to discover over the past year OEM browser libraries play a large role in device performance, even though we’re using the same Chrome build across different devices we see large differences in performance even within devices who employ the same SoC. It’s relatively unnerving to see this fragmentation in the ecosystem and in particular Chrome performing so differently across devices.
In Octane the Nexus 6P again performs very well, this time again beating our other devices such as the HTC One M9 or the Xiaomi Mi Note Pro. Among Android devices, only the Galaxy Note 5 - which on Octane is able to show equal performance as it does in its optimized stock browser - is able to beat it.
On WebXPRT again we see the 6P performs extremely well among Android devices, only being able to be beat by Samsung’s Exynos 7420 devices in the stock browser.
Continuing onto our system benchmarks, we start with Basemark OS II 2.0 from Basemark (formerly Rightware).
In the web test the Nexus 6P is yet again found at the high-end of the charts as it is able to provide good numbers. As we’ve seen in reviews such as on the Mate S it’s not necessarily raw performance that is demanded in these tests but also performance latency which plays a big role.
The graphics sub-test of Basemark has always been kind to the Adreno GPU so here again we see the Nexus 6P perform well, although not quite up to par with the other Snapdragon 810 devices we’ve tested in the past.
The Nexus 6P comes in a surprising first place on Basemark OS’s memory test. Again this is a mainly NAND-limited test but in contrast to our other synthetic test, performance and access patterns try to simulate more real-world applications.
While the other tests try to test more realistic workloads, the system benchmark is all about measuring peak performance in a given set of scenarios. Here the Nexus 6P fares similarly to the Xiaomi Mi Note Pro but falls behind Exynos 7420 devices such as the Note 5.
While I’m not a great fan of overall aggregate benchmark scores, we still see the Nexus 6P among the top of today’s currently available Android devices.
Moving on to PCMark from Futuremark, we’ll use a suite of tests that not only try to mimic real-world usage patterns, but actually make use of APIs that we currently find in use by many day-to-day applications.
Starting with the web browsing test we find the application use Android’s built-in WebView container which relies on OS-dependent components.
Here we see the Nexus 6P lead performance, slightly beating the Note 5. We’re also likely seeing advantages due to Android 6.0 as the Mi Note Pro, our other device with the Snapdragon 810 lags over a thousand points behind.
On the video playback score the Nexus 6P comes in towards the middle of the pack. The video test is a benchmark of both the video decoding hardware and software layers of the device, as well as the NAND speed, as fast seeking through the video is performed to test out how rapidly the device can resume playback.
Now onto the writing test we come to one of the larger mysteries of the new Nexus 6’s performance. Both the Nexus 5X and the 6P seem to have large issues with PCMark’s writing test. The test itself consist of text manipulation and some file I/O, but most importantly it’s that this is purely a Java based test. Due to the way Android is architected, this means the code is handled and executed by the Android RunTime (ART). Futuremark have done a fantastic job in creating a test-case which is very sensitive to performance differences in the runtime.
At first when seeing these scores I thought that this was a side-effect of Android 6.0’s new big.LITTLE optimizations (which we’ll get back to in a later section), but even after turning those settings off the scores remained the same. After testing some other Java-based benchmarks I came to the conclusion that this has to be a software issue.
The photo editing uses RenderScript kernels to apply image processing on a set of pictures. With help of a powerful GPU the Nexus 6P performs top of the class
Due to the disappointing writing sub-score the Nexus 6P ends up third in the overall PCMark work performance score. Nevertheless, this is a good showing for the Snapdragon 810 device as it manages to slightly beat the Mi Note Pro and the HTC One M9.

My Nexus 5X has a brightness slider in the notification shade. Just swipe down a second time (or swipe down once with two fingers). It also has a flashlight button, airplane mode, and WiFi setting there too.JimFoster - Friday, December 18, 2015 - link
Excellent excellent review. I can always trust AT and GSMarena. You guys usually give us the definitive review. And thank God I paid the extra and bought the Nexus 6P and not the OnePlus 2.gg555 - Sunday, December 20, 2015 - link
GSMArena provides a lot of detail. But I think they go easy on the phones quite a bit and gloss over problems. They are a bit of an advetorial site, that's there more to promote phones, than really analyze them. This is especially seen in their "news" section, that is basically just reguritating press releases.What's great about AnandTech is that they really analyze things in detail and don't hesitate to point out problems or limitations. They provide much more of an actual independent point of view.

I really appreciate AnandTech's super detailed, thoughtful reviews.But what about call quality? In call noise cancellation? Reception? It is a phone still, isn't it, or have they permanently dropped that feature?
AnandTech used to do great reviews on call quality, especially with its noise cancellation test. Now there is not a single word on anything having to do with simply placing a call.

A will take a closely AOSP-based firmware over highly "customized" any day of week. The problem with the highly customized ROMS is not their customization but the fact that those ROMS come with buttload of bloatware. Something like at least a couple of dozen apps that will nag you with registration, noticed and functionality you don't need. They will wake your devices unnecessarily and deplete your battery. Unlike in Windows, you can't uninstall this bloatware without rooting the device. I much prefer the experience of something like Cyanogenmod or Cyanogen OS (as shipped on Oneplus One). Simple, tidy, efficient.Ethos Evoss - Sunday, December 20, 2015 - link
OMG again this apples BITCH website sold themselves to them on 1000% :DD every their charts those crappy iphone on top.. anandatech u are making IDIOTS from yourself .. TOTALLY :DDDand despite everybody knows iphones as the worst battery (that is why crapple made official battery case and you STILL claiming that it has best battery life iphones??
YOU BIGGEST LIARS on the Internet !! jeesus are there so stupid ppl who believe this biggest pathetic bitch apples site ??
RIDICULOUS

Yeah breathe pleaseEthos Evoss - Sunday, December 27, 2015 - link
Am sorry, but this site choking me...amdwilliam1985 - Sunday, December 20, 2015 - link
Nexus 6P has the second best battery life(after Moto Droid Maxx) in "real life use cases". This is from someone(MKBHD) who uses a lot of smart phones, hopefully all under same/similar use cases, so I think his option is pretty valuable, might be more so than the "random" reviewers(with a very subjective opinion) from this site lately. lol.https://www.youtube.com/watch?v=UBuVR8_Mybw
Don't worry, I'm still reading this site, because even with all the BS, it is still one of the best. Well, I'm waiting for an alternative ;) Then I can stop coming back...

so I think his opinion* is pretty valuable
