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.

    You don't seem to understand, the gaming mode on the BS2 makes absolutely zero difference. It still throttles to the performance levels published here.

    As for the OPPO, that phone didn't throttle in either mode so I don't understand what you're on about. The performance mode it has is not like that of other phones and it's not a natural operational mode of the phone.

    If we could achieve a new consensus on testing battery life in default mode and performance in performance mode, then I suppose something like that could be reasonable, but many other devices would have to be retested.
  • Andrei Frumusanu - Thursday, September 26, 2019 - link

    I'm testing all devices in their performance modes both for performance and battery - the only exception to this rule until now has been the Reno as its performance mode just blatantly ignores normal DVFS operation.
  • s.yu - Thursday, September 26, 2019 - link

    Right, that also works.
  • melgross - Thursday, September 26, 2019 - link

    The point is. That it can’t maintain that speed without burning something out.
  • melgross - Thursday, September 26, 2019 - link

    Anandtech is the only site that does it correctly. The others don’t do real reviews.
  • brucethemoose - Wednesday, September 25, 2019 - link

    Or, more importantly, heating up your (non replacable) battery and degrading its useful life.
  • s.yu - Wednesday, September 25, 2019 - link

    It should all be run in whatever default mode available out of fairness, and comparability of results.
  • Total Meltdowner - Wednesday, September 25, 2019 - link

    The specs on these phones are all so boring.

    Give me an 8000mAH battery and a screen that isn't a downgrade from an S6 Active.

    How about some ports or SOMETHING that separates these devices from one another? 0 innovation. It's just a bunch of chinese garbage.

    I think you'll enjoy the ROG Phone 2 review, then.
