Xiaomi Mi Mix 3 Review, Specifications, Price

Hey guys what is up? So, Xiaomi’s Mi Mix 3 caught my attention a few days back and after scavenging the internet, I’ve compiled some results that will answer some (if not most) of the questions you may have about the phone.

As displays become one of the most important aspects on a phone, Xiaomi has taken a step to stand out with this one.

This is Shaibu from Shu’s Techs and today I’ll be giving you guys the Xiaomi Mi Mix 3 review.

With that being said, let’s get to it.

Key Features

  • MIUI 10.0 with Android 9.0 (Pie)
  • 6.39 inch 1080 x 2340 Super AMOLED capacitive touchscreen
  • Octa-core (4×2.8 GHz Kryo 385 Gold & 4×1.7 GHz Kryo 385 Silver) CPU
  • Adreno 630
  • 6GB / 8GB / 10GB RAM
  • 128GB / 256GB Internal Storage
  • 24MP + 2MP Front Camera and 12MP +12MP Rear Camera
  • 3200mAh non-removable battery
  • Dual SIM


Looking at the phone, the first thing you might ask is “where is the selfie camera?” Well, that is a reasonable question and the answer is “right behind the screen.”

No, not behind the phone, it is behind the screen and that’s because the Mi Mix 3 is a phone you can slide. Sliding the screen down reveals the dual selfie cameras (which we’ll be talking about soon).

The Mi Mix 3 has a glass build on the front, an aluminum frame and a ceramic back. It will give you a shiny and attractive look at the back but once it gets in your hands, you’ll have to start cleaning fingerprint smudges all over it.

Good thing the phone comes with a case in the box to prevent smudges. The case adds more grip to the phone and doesn’t interrupt how the sliding mechanism works.

The case has an opening at the bottom that allows the screen to slide down, as you can see from the image below.

Coming in three colors, you can choose either a Jade Green, Sapphire Blue or an Onyx Black (or all if you want).

On the back is the vertically placed dual cameras with a LED flash in between them.

Still on the back is a fingerprint reader that is reported to be really fast for unlocking the device and carrying out other security functions the phone supports.

The Mi Mix 3 is not resistant to dust so having dust getting stuck where the slider is might be something to watch out for so there won’t be scratches. There hasn’t been any reports of that happening, but I’m just pointing it out.

The phone doesn’t come with a 3.5mm headphone jack, sadly, but an adapter is provided in the box. Using a dongle on the phone can be limiting sometimes, like charging the phone while listening to music with your headphones is not possible, unless you are using a pair of Bluetooth headphones.

But, you get a wireless charger out of the box (which is a generous thing to do by Xiaomi) so in terms of using the dongle with the headphones, there is an option while it’s charging.

On the left side of the phone is a special button that is used for starting up Google Assistant. Although the purpose of just tapping the button cannot be changed, you are allowed customize it to do other things by long pressing or double tapping the button.

The overall design of the Mi Mix 3 is impressive, elements are in reachable positions, I can’t say there’s anything horrible about the design.

A case is provided to eliminate the fingerprint smudges and a wireless charger is also provided if you wish to use your headphones with the USB port.

I guess everything was thought through.


The display on the Mi Mix 3 is impressive, bezels are close to gone and the screen to body ration is 85%. That’s high enough to give you an all round display.

The phone has a Super AMOLED capacitive touchscreen and has a screen size of 6.39 inches. The largeness of the screen will give a nice experience when it comes to video watching or streaming, gaming etc.

Being a Super AMOLED screen, you know you will be getting some detailed and sharp displays.

The phone has a screen resolution of 1080 x 2340 pixels, viewing angles are also very good and color presentation is accurate.

The screen is also protected with Gorilla Glass 5, in this case, the screen should be able to survive scratches, dusts and occasional drops without getting damaged.

There isn’t a notch on the Mi Mix 3, but I guess that isn’t a problem since the screen is big enough and doesn’t have any limits.

Outdoor visibility is impressive as the phone gets bright enough with auto-brightness enabled.


Starting with the selfie cameras, the Mi Mix 3 comes with a dual camera setup, having a combination of a 24 Megapixel Main Camera and a 2 Megapixel Camera for Depth Sensing.

On the selfie cameras, you can record 1080p videos at 30 frames per second.

Pictures appear pleasant and detailed. The cameras also support portrait mode, and with the depth sensor, images come out okay.

There’s also a LED flash to make your selfies appear bright in low light conditions.

Turning to the back, there is a 12 Megapixel Main Camera and a 12 Megapixel Telephoto camera for x2 optical zoom.

On the main camera, pictures appear detailed but a little noisy. Enabling auto HDR or AI will boost sharpness and color saturation.

Night mode on the main camera takes about 2 seconds to take photos and the end results bring a lot of life into the pictures as brightness and details one each shot are increased.

The Telephoto camera also does really well in bringing out sharp and detailed dynamic range photos.

The phone supports a range of video recording modes such as 2160p at 30 and 60 frames, 1080p at 30 and 60 frames and finally 1080 at 960 frames for slow motion videos.

Overall, cameras on the phone perform well, not as great as some of the best out there but they do get the job done.


When it comes to performance, the Mi Mix 3 comes with some of the latest features.

First, it comes with Xiaomi’s MIUI 10 with Android 9.0 (Pie). With MIUI 10, you get Gesture Navigation. Swipe up from the bottom to go “Home”, swipe up and hold to see “Recent Apps”, swipe left or right from the sides of the screen to go “Back”.

Sliding the phone down also activates the selfie cameras, but that can be changed to do some specified actions that comes with the phone. You won’t be getting a lot of options though.

Call clarity is okay and audio from the speaker on the bottom  is also impressive.

The Chipset on the Mi Mix 3 is a Qualcomm SDM845 Snapdragon 845 and it is combined with an Octa-core CPU with a clockspeed of 2.8GHz.

The GPU is an Andreno 630.

The overall performance on the phone is really good, games run smooth and everything else is fast.


There are a range of options on this phone in terms of RAM. Multitasking on the phone should be super smooth regardless of the one you go for.

The Mi Mix 3 has a 6GB, 8GB and a 10GB of RAM version.

When it comes to internal storage, you either go for the 128GB of internal storage space (supported by the 6GB and 8GB of RAM versions) or the 256GB of internal storage space (supported by the 8GB and 10GB of RAM versions).

Both are good enough for having a lot of media files on the phone and you really will not be needing an SD card to expand.

If you do need to expand, sadly the Mi Mix 3 does not come with an SD card slot.

I don’t think you will quickly run out of space on this phone, but if storage is a major deal for you, then I suggest you go for the 256GB of internal storage.


I wouldn’t say this phone comes with the best battery, but the battery performance is just okay. It has a 3200mAh Non-removable Li-Ion battery.

Not an amazing one like I said but it should be able to take you a day on moderate use before running out.

Heavy users may have to charge once or twice a day.

The good thing about the phone is that it supports both fast and wireless charging. You get the phone fully charged in about an hour and thirty minutes.

The battery is this way because of the slider but it should be able to do you some good with overall durability.


The photo comes equipped with 4G LTE, 3G and 2G. Although there are rumors that a 5G version of the phone will be released, we are keeping our fingers crossed hoping it’s true because no confirmations have been made yet.

You get WiFi, USB Type-C 1.0 reversible connector, Bluetooth V5.0, dual SIM cards etc.

There’s no FM radio though.


Although I haven’t confirmed the actual price, you can get the 6GB of RAM and 256GB of internal storage around $500.

Check current prices on Amazon.

*Please note that prices vary from time to time.


Besides the battery and lack of a headphone jack I would say the Xiaomi Mi Mix 3 is a pretty good device.

It will give you maximum speed, a good user interface and a nice camera experience and most importantly, sliding the phone to pass time.

I wouldn’t really rate the phone because what is great for me might be horrible for you.
