Huawei Mate 9 Review: A smartphone that gets better the more you use it?
How's this for a unique feature? The Huawei Mate 9 is the first smartphone with a unique machine-learning algorithm that studies your habits and actually increases its performance over time. The 5.9-inch phablet also has a dual rear camera setup co-developed with Leica and a massive 4,000mAh battery. But how does all this pan out in actual use?

Overview
How's this for a unique feature? The Huawei Mate 9 actually gets better the more you use it. It accomplishes this thanks to a machine-learning algorithm that studies your habits, the types of apps you use, and when, where and how long you use them, prioritizing resources when it anticipates you’ll need them, resulting in an overall smoother experience and more efficient battery life. According to Huawei, 10,000 hours of simulated use resulted in about an eight percent performance gain! If that's not enough, the Mate 9 also has a massive 4,000mAh battery and a unique dual rear camera setup that pairs a 20-megapixel monochrome camera with a 12-megapixel RGB camera, co-developed with German imaging maestros Leica.
Priced at S$898, the 5.9-inch Mate 9 will be looking to plug the gap left by thousands of recalled Samsung Galaxy Note7s, but with strong competition from LG's V20, ASUS' ZenFone 3 Deluxe and the OnePlus 3T, it will be tough.
Design
Huawei has been making gorgeous, well-crafted devices for a number of years now, and the Mate 9 is no exception. Having said that, it's not the most exciting design out there, especially because it looks so similar to the Mate 8 (which was only released nine months ago). The screen has shrunk to 5.9-inches (rather than the 6-inches of the Mate 8), which means the dimensions are marginally reduced - but not in any way that's noticeable. The frame now has rounded sides, similar to the iPhone 6 and 7, and the back finish is now glossy instead of matte. Personally, I'm not a fan of the glossy finish as it doesn't feel as nice, and it also picks up smudges and fingerprints far easier than the old matte finish.
The only real visual clue that you're dealing with the Mate 9 instead of the Mate 8 is the dual-lens camera on the back, which has the word Leica faintly printed between the two sensors. Like its predecessor, there's a slightly indented fingerprint sensor below the camera.
The phone's left edge houses a dual-SIM tray, and one of the slots also doubles up as a microSD card slot. On the right, you'll find both the power button and volume rocker.
On the bottom, the micro-USB port has been replaced with a USB-C port, while on the top edge you'll find a 3.5mm headphone jack.
If you're looking for a more exciting Mate 9, consider waiting for the upgraded Porsche Design version, which is rumored to be releasing early next year. This version is slightly smaller at 5.5-inches, and sports a slick black graphite finish. It also has a curved display (similar to the Samsung Galaxy S7 Edge) and an integrated physical home button/fingerprint scanner on the front of the phone. More details on the Porsche Design version here.
Display & Audio
Despite having one of the largest displays on the market, the Mate 9 only has a Full HD 1,980 x 1,020 pixels resolution display, which gives it a relatively low 373ppi. Having said that, clarity is good enough, and the IPS LCD panel is one of the better ones out there, with rich colors and reasonably good contrast. The screen also gets very bright, with a maximum of 677 nits, making it easy to view, even under the brightest lighting conditions.
As with many phones today, Huawei has included an option for adjusting the color temperature of the screen as well as an "Eye Comfort" mode, which gives the screen a warm, yellowish cast. This is very similar to Apple's Night Shift mode, which is better for your eyes at night.
Audio from the Mate 9 comes from a single bottom-mounted speaker. The speaker is quite loud, but lacks both bass and high-end range. It also gets a bit distorted if you crank it to maximum volume.
Software
The Mate 9 runs on Android 7.0 Nougat with Huawei's Emotion UI 5.0 on top of it. EMUI has several differences from stock Android, with the most obvious being the removal of the apps drawer. Instead, all of your apps live on the home page similar to iOS. Interestingly, there's now an option to restore the app drawer, but it's hidden in the Settings menu.
Surprisingly, Huawei has also adopted more of Google's own features rather than force its own version of the same thing on you. For example, the Mate 9 now uses Google's default split-screen multitasking feature rather than its own solution like previous Huawei devices. To use it, just press and hold the recent apps button when you're in an app. This will split the screen in two, pushing your current app to the top half of the screen and showing any recently opened apps in the bottom half. Scroll to the one you want and tap it to split-screen.
Further solidifying Huawei's partnership with Google, the Mate 9 is one of the world's first Daydream-compatible phones. That means works with Google's new Daydream VR platform. Unfortunately, the Daydream VR headset isn't currently available locally, but when it does launch, at least you'll have a phone you can use it with!
Of course Huawei has also added a few of its own features to the phone. Floating Dock is an interesting new feature that can be accessed from the Quick Settings panel. When enabled, it places a small circle on the screen. You can anchor this to the left or right side of the display, and tap it to show the home, back and all apps keys that are also at the bottom of the screen. This makes it much easier to navigate the huge display because it saves you from having to stretch your finger all the way to the bottom to reach the buttons. This feature is very similar to the touchscreen Home Button you can enable in iOS.
As with previous Huawei phones, you also get Knuckle Sense, which is Huawei's knuckle control system. Most of the gestures carry over from previous models, so for example, you can knock the screen twice with your knuckle to take a screenshot, or write on-screen letters with your knuckle to launch apps. This feature is still as weird as it was when we first saw back on the Huawei Ascend P7, but it's gotten more responsive, and it's now much better at differentiating between deliberate knuckle gestures and accidental screen pokes. If you can remember a few of the gestures, it's actually quite useful.
Huawei's much touted Machine Learning algorithm is always running in the background of EMUI 5.0. Huawei claims that the algorithm will actually make your phone better over time . In addition to maximizing CPU, memory, and storage efficiency, the Mate 9 also allocates more storage and RAM to intensive programs, and will remember which apps you use most frequently to start them up faster. For example, if the first thing you do every day is open the Facebook app, the Mate 9 will remember this behavior and will start diverting resources to prepare Facebook to load up at around the same time every morning. Unfortunately, in the last few days of using the Mate 9 I haven't been able to see any improvements yet, so you're not likely to see the benefits of this feature until you've used the Mate 9 as your primary smartphone for quite a while.
Performance Benchmarks
As usual for Huawei, the Mate 9 uses an in-house Kirin SoC. The Kirin 960 uses four of ARM’s new Cortex-A73 cores and four low-powered A53 cores. It's also the first processor to ship with the new Mali G71 MP8 GPU, which should result in better gaming performance and graphics thanks to a quoted 180 percent speed increase over the T880 used in the Mate 8.
Sunspider Javascript
SunSpider JavaScript measures the browsing performance of a device when processing JavaScript. It not only takes into consideration the underlying hardware performance, but also assesses how optimized a particular platform is at delivering a high-speed web browsing experience.
The Mate 9 performed quite well here, beating everything except for the Galaxy S7 Edge and Apple iPhone 7 Plus. The actual usage experience was generally smooth, with only slight jitters on resource-heavy websites.
Quadrant
Quadrant is an Android benchmark that evaluates a device's CPU, memory, I/O and 3D graphics performances. As this is an Android benchmark, the Apple iPhone 7 Plus is not included. The Mate 9 performed much better than the Mate 8 but lagged slightly behind both Snapdragon 820-equipped devices. We haven't been able to benchmark an 821 device, but it should score even higher, which unfortunately would put the Mate 9 even further behind. Samsung's Exynos 8890 continues to be untouchable in this benchmark.
3DMark Sling Shot
3DMark Sling Shot is an advanced 3D graphics benchmark that tests the full range of OpenGL ES 3.1 and ES 3.0 API features including multiple render targets, instanced rendering, uniform buffers and transform feedback. The test also includes impressive volumetric lighting and post-processing effects. We're running this benchmark in Unlimited mode, which ignores screen resolutions.
The Mate 9 once again lagged slightly behind both 820-equipped processors, and was considerably weaker than both the S7 Edge and iPhone 7 Plus. It did however live up to expectations somewhat as it was greatly better than its predecessor.
Imaging

Huawei has once again teamed up with Leica to co-engineer its imaging system. Like the Huawei P9, the Mate 9 has a dual-lens system on its rear. However, the Mate 9 camera setup is a bit different from the P9 and other dual-camera phones like the LG V20 and iPhone 7 Plus, as the Mate 9's is split into monochrome and color sensors, with the 12-megapixel sensor capturing RGB data and the 20-megapixel sensor capturing monochrome information. Combined together, they deliver richer colors and finer details.
You can use the monochrome sensor independently, but unless you really like black and white photography, it's generally better to use both together.
Because the monochrome lens has a higher resolution than the color one, Huawei says it can do “hybrid zoom.” While this may sound like a combination of optical and digital zoom, as far as I can tell, there's nothing optical about it. Huawei's Hybrid Zoom seems to just be digital sensor cropping, where a photo is taken at a higher resolution and then cropped, something that we've seen before from the old Nokia Lumia phones, and more recently Sony.
Like the iPhone 7 Plus, the Mate 9 has a bokeh mode (called 'Wide Aperture' by Huawei) which aims to replicate background bokeh. The results aren't the best though and the algorithm is bad at distinguishing edges, often blurring out the wrong part of the photo.
Overall picture quality on the Mate 9 is quite good on standard usage, with photos taken under good lighting coming out sharp with good detail reproduction and accurate colors. Some pictures do look a little over processed, and the auto-HDR is a little aggressive for my taste, but it does the job. Due to the relatively narrow f/2.2 aperture, low-light photography isn't the best, and even though the sensor has 6-axis optical image stabilization, pictures tend to be a hit-or-miss if there's not enough light.

Battery Life
Our standard battery test for mobile phones has the following parameters:
- Looping a 720p video with screen brightness and volume at 100%
- Wi-Fi and Bluetooth connectivity turned on
- Constant data streaming through email and Twitter
The Mate 9 has a massive 4,000mAh battery, giving it one of the highest capacity batteries out there. In combination with its Full HD display, this resulted in excellent battery life.
Huawei is also introducing its own fast-charging technology called Super Charge, which works much like Qualcomm's QuickCharge or Samsung's Fast Charge technology. Huawei claims that with Super Charge, the Mate 9 can reach about 60 percent charge in 30 minutes, which would put it on par with other quick charging technologies out there. However in my own testing it took longer than that, requiring nearly an hour to reach 60 percent.
Conclusion
Ultimately, despite all of the technology Huawei has crammed into the Mate 9, its two best features are its huge display and excellent battery life. While that makes it perfect if you spend all of your time watching videos on your phone, for S$898, we expect a little more.
Neither of the Mate 9's two big features, the machine-learning algorithm and Leica dual camera setup, were particularly outstanding and it still remains to be seen if the machine-learning really can deliver on the eight percent increase in performance Huawei is claiming. Mind you, eight percent is unlikely that you would actually get to feel any change in performance even if benchmarks show it. It's also worth noting that even if it does get a boost in performance, Huawei's Kirin 960 SoC still trails behind the flagship processors from Apple, Samsung and Qualcomm.
The Leica dual-lens setup looks good on paper but the results weren't as impressive in actual use. The whole setup is also let down by a mediocre f/2.2 aperture that struggles under less than ideal lightning conditions.
If you're looking for a powerful phablet to replace your Note7, OnePlus' new Qualcomm Snapdragon 821-equipped OnePlus 3T will outperform the Mate 9. While not officially available locally, there are also many options for getting your hands on Google's new Pixel XL, which also runs on a Snapdragon 821. Alternatively, LG's V20 uses the older 820 processor (which still slightly outperforms the Mate 9) but packs in a ton of interesting audiophile, photography and video features and also has a higher resolution QHD display.
