Slider mechanism as in olden times

The fact that the Mi Mix 3 is equipped with a slider mechanism is not great news. The Xiaomi CEO Lei Jun himself had posted a photo of the upcoming Xiaomi Mi Mix 3 via Weibo during the last weeks. It already showed a very bezel less smartphone, which doesn’t work with a pop-up camera, but with a slider mechanism. This is a strategy to realize a smartphone as bezel-less as possible.

Unlike the Oppo Find X, however, you have control over this mechanics yourself. This mechanical slider is a feature that Xiaomi itself aggressively promotes as a “lifestyle feature”. The opening of the slider can also be accompanied by music. Xiaomi offers the user five tone options, which the mobile phone can play when using the slider. With the VIVO Nex you could also select different sounds for the pop-up front camera.

The first Mi Mix with AMOLED

In contrast to its predecessors, the display has now been enlarged. While the last two generations still used a 5.99 inch display, the new device uses a 6.39 inch display. This is an AMOLED display; a novelty for the Mi Mix series. The screen-to-body ratio is correspondingly high at 93.4%! The slider mechanism of course also eliminates the need for the notch, as the front camera only shows itself when the display is pushed down. Xiaomi uses an aspect ratio of 19.5:9 and a screen resolution of 2340 x 1080p, which is referred to as Full HD+.

The last two Mi Mix devices were initially available in two different colors: black and white. Later an additional green edition was released. The Mi Mix 3 starts directly with several color variations including the Jade Green and a blue version. In addition there is of course a standard black!  On the back there is a dual camera, which is arranged vertically again.

So the back reminds us of the last Mix model again, glass is used here as well. Therefore there is also support again for wireless charging with Qi. Only the “Forbidden City” edition is set in ceramic.

The Xiaomi Mi Mix 3 will be equipped with a standard fingerprint sensor on the back. This is exactly where we see it on almost every Xiaomi smartphone by now. A fingerprint sensor in the display is therefore exclusively reserved for the Xiaomi Mi 8 Explorer Edition and the Xiaomi Mi 8 Pro.

In the past, Xiaomi used additional physical keys rather sparingly. Now the Mi Mix 3 uses a dedicated Xiao AI button to start the voice assistant and give voice commands. After all, the Xiao AI Language Assistant from Xiaomi will play an increasingly important role in the future.  In addition, it seems as if the button could be assigned a second function by pressing it twice quickly.

Focus on the front camera

In terms of the camera, Xiaomi hasn’t changed too much. The main sensor remains the 12 megapixel Sony IMX363, which we saw in the Mi Mix 2S for the first time in an Xiaomi smartphone. With an aperture of ƒ/1.8, the camera is pretty fast. The secondary sensor is the Samsung S5K3M3 with a ƒ/2.4 aperture and also 12 megapixels.

AI again plays an important role here, the use of artificial intelligence got more attention for the first time when the predecessor was introduced. Xiaomi once again uses the DxO benchmark as a quality feature, which is used as a reference for good camera quality. There, the Mi 8 recently achieved a very good 99 points, the predecessor of the Mix 3 also came off well with 97 points. The new Xiaomi Mi Mix 3 reaches a benchmark value of 103 points, which is divided into 108 points in the photo area and 93 points in the video area. Thus, it scores just as many points as the Samsung Galaxy Note 9!Xiaomi Mi Mix 3 example picture

As with the Galaxy Note 9, Xiaomi has also focused on low-light improvements. Lin Bin, co-founder of the company, already proved this with a photo on the social media. In the keynote they referred to this again and compared the results directly with the Huawei P20 Pro.

Another similarity to Note 9: the Super Slow-Mo. With the Mi Mix 3 you can record videos at 960fps, i.e. frames per second. So you can record very good slow-motion videos with it.

The front camera also consists of two lenses. There Xiaomi combines a 24 Megapixel sensor, the Sony IMX576 and a secondary 2 Megapixel sensor. This should probably improve the front portrait mode. Again, Xiaomi couldn’t hold back a direct side blow against the competition. But a mere comparison of resolutions is not so meaningful for cameras.

New or old flagship hardware?

In advance, the processor question was an important detail, which was hidden until the end. Now it is clear that a Snapdragon 845 processor has been installed, just like in all current top Xiaomi models. It is still the top processor from Qualcomm. The Octa-Core with up to 2.8 GHz was also used in the Xiaomi Mi Mix 2S. So we still have to wait for the Snapdragon 855; maybe it will be used in the Mi Mix 3S.

Xiaomi Mi Mix 3 RAM

Xiaomi sets an example when it comes to RAM. The Xiaomi Black Shark Helo is indeed the first smartphone with 10 GB RAM. However, the Mi Mix 3 is also equipped with an impressive 10 GB of RAM. Of course, this is the maximum configuration, because the Mi Mix 3 is also available in smaller versions. So you have the choice to equip the new top model with 6, 8 or 10 GB RAM and 128 or 256 GB internal memory.

Xiaomi Mi Mix 3 with 5G support

Xiaomi’s product manager had already posted a picture of an unnamed smartphone on Twitter in advance. What was so special about this picture? The display showed “5G” next to the reception columns, which indicated that Mix 3 would come with 5G support. And indeed: the Xiaomi Mi Mix 3 is the first smartphone with 5G support. However, the current model doesn’t support 5G yet. A 5G version of the Mi Mix 3 will be released early next year.

The successor to the 4G standard provides for extremely fast mobile Internet and is therefore of course very future-oriented.

Price & Availability

The Xiaomi Mi Mix 3 is just as expensive in the cheapest version as the Mix 2S at launch. With 6 GB and 128 GB it costs 3299 Yuan, which is about 475 USD. The medium version with 8 GB RAM and 128 GB memory costs 3599 Yuan, which corresponds to approx. 520 USD. The version with 8 GB RAM and 256 GB costs in China 3999 Yuan, thus 575 USD. The prices in the China shops should be about $50 higher.

Xiaomi Mi Mix 3 Forbidden City Edition

There is also a special edition, the “Forbidden City”, which is launched in cooperation with a Chinese ceramics manufacturer. This Mi Mix 3 is blue and a Chinese mythical creature called Xiezhi adorns the back of the device. The 10 GB RAM mentioned above are also used here. With an additional 256 GB of memory, it costs 4999 Yuan, which corresponds to approx. 720$. Xiaomi therefore pays dearly for the 10 GB RAM.

The Mi Mix 3 can be pre-ordered in China from today on. As soon as it is available in the China shops, we will inform you of course!

Our assessment

Here it is now, the Xiaomi Mi Mix 3, a smartphone at last that stands out from the crowd. The slider mechanism was already known in advance, but should be the big highlight of the new top model. A screen-to-body ratio of almost 94% is impressive and shows how much expertise Xiaomi has accumulated in the meantime. But the big performance leap doesn’t happen. We have now seen the CPU in enough smartphones and the 10 GB RAM can be found exclusively in the expensive Palace Edition, which will probably not be picked up by many.

We are curious about the camera! After all, Xiaomi spent most of the keynote time talking about the improved features and turned out to be better than the competition. The DxO benchmark confirms the assumptions, but of course we want to take some photos with it ourselves. That’s why we’re now counting down the days until the Mi Mix 3 arrives and then we’ll test it extensively!

What do you think of the new/old slider mechanism? Can the Xiaomi Mi Mix 3 convince you?
