Huawei Mate 8 review: Time-saver edition


The Huawei Mate 8 is the latest phablet by the Chinese phone manufacturer. It’s a premium device all around and it surely doesn’t come cheap. But for the price you pay for it, you are certainly treated to an excellent user experience and some of the best specs in the industry.

Key specifications

6.0″1080×1920 pixels


HiSilicon Kirin 950

64GB memory


Following in the footsteps of the Mate7, the new phablet is also one seriously good-looking smartphone. It’s like a tuxedo in a world of jeans and sweaters. It clearly means business.

Design and build quality

The Mate 8 has an unmatched high-end vibe, thanks to precision-machined metal and glass components, and sharper, bolder edges.

The Huawei Mate 8 is very compact for a 6-inch smartphone. It is, in fact, 4.2mm shorter than the 5.7-inch Huawei-made Nexus 6P, and a millimeter shorter than the iPhone 6s Plus, which only has a 5.5-inch display.

The Mate 8 features an aluminum unibody, well befitting its flagship status (and price, too). The back has been sandblasted for a fine satin finish. However it’s not removable and you have no access to the battery.

The Mate 8 comes with what has become known as a hybrid DualSIM/microSD card slot. What it means is that there are two card slots on the phone – the first one is for your main SIM card and it can connect to LTE networks. The second slot however can either be used as a secondary SIM slot (2G-only) or for a microSD card. Depending on your needs, this can be a good or bad thing.

One of the best aspects of the Mate 8 is its fingerprint sensor on the back. It’s is one the best implementations on the market, always on, blazing fast, and rarely erring. The sensor is always on, and it will unlock the smartphone and take you to the homescreen in what can be described only as a ‘mere instant’. You can also set it up to take photos, answer calls or turn off your alarm.

Design and build quality score



The 6-inch display on Huawei Mate 8 has FullHD resolution, which equals 1080 x 1920 pixels. At 368ppi, it’s comfortably above what Apple coined as Retina resolution, and should be less taxing on the battery and graphics chip.

Huawei Mate 8 review

The Huawei Mate 8 uses an IPS-NEO LCD panel by JDI, which delivers deeper blacks. The blacks don’t look spectacular when compared to those on an AMOLED display, but they are still noticeably better than on any regular IPS LCD.

The maximum brightness level achieved by the screen when displaying white is 471nits, which while not award winning is plenty to go by. The offered contrast ratio, however, is excellent – 1361:1. The Mate 8’s solid performance in our display tests continues into sunlight legibility.

Regarding color reproduction accuracy the Mate 8 screen is less than stellar with an average deviation (DeltaE) of 6.1 a bit higher than what we would ideally like. We’ve seen worse even in flagship devices, so this one sits somewhere in the middle. For a screen to be considered properly calibrated it needs to have a maximum DeltaE of 4.

Battery life

The Mate 8 battery comes with an extra large capacity – 4,000mAh. The phone supports fast charging and can recharge the 9V/2A fast-charging technology can recharge that large battery in 2.5h. There is no wireless charging support. A mere 30-minute charge is rated to provide a full day of use.

Huawei Mate 8 review

Through our dedicated tests the Mate 8 scored an endurance rating of 103h in single SIM mode, which is an estimation of how long the phone would last if you use it for an hour each of calling, browsing and video playback a day.

Such usage pattern may not be relevant to your own usage scenario, but we’ve established it so our battery results are comparable across devices. You can adjust the formula to better match your own usage pattern, by visiting our dedicated battery test results page.

The 103h rating of the Mate8 is a splendid performance. There aren’t many phones that can pull off a triple digit score in our test. What’s more important is that no current competitor in the high-end segment can come anywhere close to its longevity when surfing the web, even if there are those that outlast it in video playback.


The speaker on Huawei Mate 8 unfortunately, scored a Below Average mark in terms of loudness. The Galaxy Note5 and the LG V10 are only slightly louder, but the Lumia 950 XL excels in this respect.

The Huawei Mate 8 however did marvelously in our audio output quality via the 3.5mm audio jack.

While connected to an active external amplifier, the smartphone’s output was clean, while its loudness was well above average, making up for one of the best showings out there.

Even more impressively, plugging in a pair of headphones causes next to no distortion – even the hike in stereo crosstalk we’ve come to expect is very minor and the end result is excellent. None of the other readings are affected either and volume levels stay high for an impressive showing.

Photo camera

The Huawei Mate 8 camera uses a 1/2.8″ sensor with 16MP resolution made by Sony. There’s optical image stabilization too and phase detection auto focus. A dual-tone LED flash can help out in the dark and will also produce more realistic flash photos.

The camera outputs noticeably soft images, which lack the detail and texture we’ve come to expect from high-end smartphones. There also was an awful lot of noise in all but the brightest portions of the images.

Colors are rendered on the conservative side – punchy is not what they are. In broad daylight, the Mate 8 exposes consistently accurately, without variations from shot to shot. Dynamic range is decent, with only a slight tendency to clip the highlights.

The front camera of the Mate 8 is an 8MP unit. There is enough detail, little noise, good dynamic range and pleasing colors. There is also a nice-looking background blurring.

Video camera

The Huawei Mate 8 is capable of recording videos in up to 1080p resolution – in either 30 or 60 frames per second. Strangely, the Mate 8 misses on 2160p (4K) video recording, while most of the competition already offers that.

At least video recording makes use of the Optical Image Stabilization system and videos come out nice and steady even when handheld. The videos taken by the Galaxy Note5 , however, are better stabilized.

When it comes to video quality, however, there isn’t much room for praise. Videos lack the detail you’d expect from that resolution and have limited dynamic range. At least, there isn’t an annoying focus hunting and they are smooth and steady.
