Over the last 1-2 years we’ve seen a new type of smartphone category start carving itself a niche in the market: the gaming smartphone. Last year, the original Black Shark was amongst the first devices to try to cater to a gaming audience, offering characteristic “gaming designs” as well as promising to offer software features to differentiate itself from the more usual smartphone offerings.

This year, Xiaomi has updated its Black Shark line and brand with the new Black Shark 2. The phone is very much a continuation of what we saw last year with the Black Shark, but offering the newest hardware innards and iterative improvements to the design and features.

The premise of a gaming phone is a bit of an odd one. The one aspect that differentiates classical gaming products from regular ones is their more exotic and futuristic design as well as the notion that they’re optimised for the gaming experience. I think the wider audience would understand the latter point as not only including features that simplify or augment the gaming experience, but also just plainly optimise the raw gaming performance of a device. In this regard, gaming phones pretty much just have one aspect in which they can greatly differentiate themselves and improve upon other “regular” devices: thermal design and heat dissipation. Indeed, more recently we’ve seen products that specifically try to highlight their improved thermal capabilities, which in turn allow for higher and longer sustained gaming performance. Today we'll be investigating how the Black Shark 2 fares in this area, and if it's able to fulfill the expectatons of a "gaming phone".

Naturally, a gaming phone requires the best SoC available, and in this regard the Black Shark 2 remains relatively in-line with what’s available in the market, featuring a Snapdragon 855 SoC. The SoC should enable excellent gaming performance as we saw the Adreno 640 to be quite competitive if it’s able to unleash full potential.

In terms of memory, the phone comes in either 8GB or 12GB RAM configurations, with either 128 or 256GB of UFS 2.1 storage.

The front of the phone is relatively classic and more in line with 2017 designs. We see a 19.5:9 aspect ratio AMOLED screen with at resolution of 2340 x 1080. In terms of gaming features, the one aspect in which the display differentiates itself isn’t by the panel itself, but rather by the touch screen. Here Xiaomi claims to offer a 240Hz touch controller which is meant to reduce input lag compared to other 60 or 120Hz devices in the market.

Indeed, in my subjective experience with the phone, I noticed that its touch responsiveness is much better than that of other devices. The tap latency improvements aren’t as quite noticeable in everyday usage, but the scroll latency is quite distinctively improved, with screen content able to follow one’s finger significantly better.

Overall while being a gaming phone, it’s not quite as oversized as you’d expect – at 75.01mm wide it’s still very much in the range of comfortable and useable by most people.

The back of the phone accentuates the whole design of the phone. The device is mainly solid aluminium – both on the sides as well as middle of the phone. The middle metal piece feels non-continous to the rest of the body of the phone, being interrupted by a glass inlay surrounding it. The design seems to help with the gaming aesthetics as well as the weight of the phone as there's a bit less metal employed. I’m not quite convinced by the build quality because when pressing the back near the “S” logo I can clearly feel the panel flex a bit and touch the internal components / battery, meaning there’s a small air gap on the inside.

Camera wise, the Black Shark 2 adopts a similar camera assembly as the Mi9, minus the wide-angle. The main sensor is again Sony’s IMX586 sensor, paired with an f/1.75 aperture lens. There’s no OIS on the phone which doesn’t bode too well, as we’ve seen the sibling Mi9 fall flat on its face in low-light conditions. The secondary module is a 2x magnification telephoto module with a 12MP sensor and an f/2.2 aperture.

The top and bottom of the phones are relatively barren – we see just a microphone hole at the top, whilst finding the USB-C connector as well as the dual nanoSIM slot at the bottom. The design is characterised by two large chamfers surrounding the phone, adding to the design of the phone.

The sides of the phone are a bit more populated; we find the regular volume rockers as well as power buttons on the left and right side, but we also find a toggle switch above the power button. This is the “Shark key” that puts the phone into Shark mode.

Alongside both sides we find two LED strips which can showcase the charge level of the device when charging – varying in strip length and colour from red to green.

On the software side of things, Shark mode and the "Shark Space" is essentially a secondary launcher interface that mimics the home screens of console UIs, with a basic listing of installed games as identified by the launcher. In the case that a game is not identified, you can still manually add apps to the list.

While in-game, you don’t really notice much difference to a regular phone, with the exception if you swipe from the bottom right (top right in landscape) corner you get an OSD menu with some options. In general, there’s not too much useful in here – under the advanced menu you get some performance monitoring options and notification toggles. There’s an FPS OSD overlay you can switch on, which can be interesting, although the CPU frequency and electrical current draw (not power) options are not very useful.

The one interesting and useful addition the Shark mode enables is “MasterTouch”, which is two pressure sensitive mapping areas which can be set up as actuation zones for configurable virtual click functions anywhere on the screen. This is actually an interesting addition and is particularly useful for shooter games where you’re using virtual analog sticks for movement and aiming, enabling you two additional functions without lifting your fingers off the screen.

Turning off gaming mode while inside a game doesn’t really change much and you still get your FPS OSD and MasterTouch still works -  but flipping the toggle switch back on will interrupt your game and bring you back to the Shark launcher.

Overall, the software features of the Black Shark 2 were interesting but nothing really extraordinary that would dramatically differentiate the phone from other devices. The pressure sensitive screen and the MasterTouch feature I found was the only worthwhile addition to the “Gamer Studio” software suite.

Naturally, what should really define a gaming phone is its performance, so let’s move on to see how the software stack and hardware is optimised for this task.

    Thanks Andrei, also and especially for calling a (now major) manufacturer -Xiaomi- out for having benchmark cheating built into their software! The hardware side is just as bad - why all style, no substance? The aluminum case almost screams for use as a heat sink, especially now that phones are all closed up.
    Regarding gaming phones: will you have a chance to test the ASUS ROG2? Might tell us if all these "gaming" phones are all smoke and mirrors. The ROG 2 is even more expensive, so it'd better be spectacular.
  • Andrei Frumusanu - Wednesday, September 25, 2019 - link

    We'll have a ROG2 review out next week.
  • s.yu - Wednesday, September 25, 2019 - link

    Andrei, please be sure to dig into Mate30P's slo-mo with detail, now that the 1-to-4 frame interpolation is confirmed, I'm not the only one suspecting that the 720P is also interpolated from an inferior readout that skips even more lines!
  • isthisavailable - Thursday, September 26, 2019 - link

    The Rog phone 2's size and weight look huge. Can you please include it's everyday usability in your review? I'm tempted to buy but 77cm wide and 9mm thicc phone looks a bit too much. And 240g weight!
  • brucethemoose - Wednesday, September 25, 2019 - link

    I can tell you the Razer Phone 2 is the real deal. Performance is fine, but holy heck, the screen! Im not even a phone gamer, but 120hz is like night and day, and you couldn't pay me to go back to a phone with a 60hz display.
  • s.yu - Wednesday, September 25, 2019 - link

    What do you think of 240Hz then? A phone with that was just released by Sharp.
    Mediocre phone by other metrics though.
  • brucethemoose - Wednesday, September 25, 2019 - link

    Its probably pretty similar, as Razer uses the same Sharp LCD line those Aquos phones use.

    But on 120hz vs 240hz specifically... I don't know? I've never even laid eyes on 240hz anything. I'd guess that you need more tightly integrated VRR support from base Android and something faster than an LCD to really make use of it, but what do I know?

    Also, for a $400 phone, the RP2 is suprisingly good by other metrics. Its not perfect (no 3.5mm, no OLED, 845 instead of 855), but I don't feel like I traded much off to get 120hz.
  • hemedans - Wednesday, September 25, 2019 - link

    RoG 2 is around $500 base model with 128GB/8GB memory, probably best Gaming phone for now, waiting for Review too.
  • s.yu - Wednesday, September 25, 2019 - link

    I thought that was the Chinese "Tencent special edition" price, yet I checked and at least India gets the same seems US customers get ripped off...or is only the top tier available there?
    $500 sounds good but 128GB really doesn't last.
  • Tams80 - Thursday, September 26, 2019 - link

    Well, the Tencent thing is a deal between ASUS and Tencent (I'm guessing mainly subsidised by Tencent). I'm guessing India is a mix of a deal with some company and lower variation due to India having lower household incomes.
