Google Nexus 6 Review

Conclusion

Recent Nexus devices have delivered great value, offering flagship hardware at mid-range prices. In order to reach the lower price point however, some compromises had to be made. For the Nexus 6, Google chose to go in a different direction, eliminating the compromises and the value. With a starting price of $650, it must compete with the other expensive flagship phones on pure performance and user experience. Based on the history of the Nexus brand and Motorola's input, we had high hopes for the Nexus 6.

One of the primary draws for any Nexus device is getting the latest pure Android experience. Lollipop brings a redesigned interface and a new Java runtime environment, among many other improvements, to this Nexus. The clean look of Lollipop's Material Design language is a refreshing change, as is the improved functionality of the lockscreen. There's now a proper do-not-disturb mode, and the profile feature previously available on tablets is now available for phones too. The scrollable recent apps menu works great until too many open apps accumulate, which makes it difficult to locate the one you want. There's also no way to just close all apps at once, definitely a UI oversight.

Ambient Display is a simple but excellent addition to the Nexus 6. It basically eliminates the need to hunt for the power button. If the phone is sitting on a table, simply rocking it on its curved back shows the time and notifications with minimal power draw. Picking up the phone or taking it out of your pocket will do the same. It's really a great convenience feature.

Drawing design inspiration from Motorola's Moto X, the Nexus 6 is an attractive, well-made phone. The combination of aluminum and plastic strikes the right balance between rigidity and weight, both extremely important in such a large device. While we like having the power and volume buttons on the same side, a little more space between them would make them more distinguishable and easier to operate, but this is a minor quibble.

The lack of a removable battery and microSD support are more serious offenses. With the Nexus 6, you're limited to a maximum of 64GB of storage. That's enough for many road warriors, but not all. Having the battery sealed inside will eliminate this Nexus from many people's wish list, though some will find solace from the Qi wireless charging and the included power adapter that supports Qualcomm's QuickCharge 2.0 technology that gets you from near-dead to over 20% in only 15 minutes.

After living with the Nexus 6 for awhile, we can say that the initial misgivings about its size dull. Yes, nothing changes the fact that its dimensions can be inconvenient, and it can be difficult finding places to stash this beast. However, by minimizing the bezels around the screen, it's really not much taller than the iPhone 6 Plus. Its significant width all but eliminates one-handed use, though.

This brings up one of our pain points. The Nexus 6 lacks any phablet-specific software features that make it easier or more productive to use: no special stylus features, no one-handed modes and no multi-window capability. Since stock Android does not offer any of these large-screen enhancements, why use a phablet as Lollipop's showcase device?

Existential questions aside, the Nexus 6 is packed with high-performance hardware, including the Snapdragon 805 SoC. The Adreno 420 GPU, along with copious amounts of memory bandwidth, showed greater than 50% improvement over the previous-gen Adreno 330 in several of our tests. CPU performance was not nearly as impressive, its bump in clock rate offering barely tangible gains over the Snapdragon 801 while consuming more power. We did find that the Nexus 6 was less prone to thermal throttling than the Galaxy Note 4, which also uses a Snapdragon 805 SoC.

Google's decision to enable Android's Full Disk Encryption (FDE) is terrific for security. Unfortunately for the Nexus 6, it's not capable of performing the file encryption/decryption in hardware. The end result is a drastic reduction of the internal storage performance. While the use of a RAM cache will mitigate the impact somewhat, apps take longer to load on the Nexus 6 versus its competitors.

We found the audio experience on the Nexus 6 to be pleasantly surprising. The dual, front-facing speakers have enough separation on a six-inch device to provide a decent stereo effect. Driven by powerful amplifiers, they get seriously loud without garbling the sound with distortion. The positive sonic experience carries over to the headphone jack, which is nearly indistinguishable from an iPhone or Z3.

Unfortunately, the Nexus 6's camera performance is merely OK. With good lighting, it captures images with plenty of detail and proper exposure. White balance is generally good, although we did notice a slight blue shift in some cases.

It's when the light dims that camera performance fades. The Nexus 6 fails to utilize OIS to improve low-light performance, producing darker, noisier images than competing cameras. The iPhone 6 Plus, for example, uses OIS to hold its shutter open three times longer than the Nexus 6, holding a much lower ISO and minimizing noise. It's not clear if the Nexus' camera software just is not optimized to work with OIS or if the feature is not actually enabled.

The 5.96-inch AMOLED display is both the Nexus 6's most distinguishing feature and its biggest disappointment. Lacking a proper sRGB display mode and not performing any screen calibration is unacceptable in this price tier. Even the $150 Moto E comes with a decent-looking, calibrated screen. The overly saturated neon colors will degrade the user experience for many people.

Considering the uncalibrated screen, missing OIS, slow internal storage and outdated graphics driver, we can't help but feel that the Nexus 6 was rushed to market. The good news is that these problems can be fixed with software updates. In fact, the Android 5.1 update includes a new graphics driver and improves the storage read performance, at least somewhat (see how the Nexus 6 performs with Android 5.1). The bad news is that the screen and OIS issues persist. The Galaxy Note 4 offers equivalent or better hardware and phablet-optimized software, making it a more compelling choice. However, if you want a large phone, don't mind the vivid colors and prefer getting your software updates directly from Google, the Nexus 6 is your beast.
