Xiaomi Mi MIX 4 vs Xiaomi Mi 11 Ultra

July 3, 2022

Comparing the Xiaomi Mi 11 Ultra with the Xiaomi Mi Mix 4 enables you to check their respective specs scores and unique features. It would potentially help you understand how the Xiaomi Mi 11 Ultra stands against the Xiaomi Mi Mix 4 and which one you should buy.

Xiaomi Mi Mix 4: Unboxing & Design

The box is not as small as the Mi 11 series, as you can see, the Mi Mix 4 box is pretty large. When you open the package, the new slogan of MIX comes into view. Translated into English, it means “There is no perfection in the world, but there is always someone in pursuit of perfection”.

Next you see the Xiaomi MIX 4 itself, let’s put it aside for now and see what accessories come with it. A phone case, a headphone adapter, a data cable, and of course the most important accessory, a 120w charger.

Xiaomi Mi Mix 4

The MIX series has pursued a full-screen design right from its inception. Although the MIX 4 is not the first phone to use the under-display camera technology, it has done a very good job with the full-screen effect.

In everyday use, even if you look carefully, you won’t easily spot the camera area. Just from the display effect, it has reached a highly usable state. Of course, it is not perfect, as from the side view, you can still see the position of the front camera. In bright light, there will also be a sun logo to protect the front camera area of the screen. And Xiaomi has made a hole in the display panel for better front camera quality. However, I hope future versions won’t have a hole in the screen because only then it will have a better full-screen effect.

Xiaomi MIX 4 Under Screen Camera

Compared to the first generation, the MIX 4’s design is kind of less impressive. Like many other phones, there is a matrix rear camera in the upper left corner. The new gray color scheme is very elegant, and the blue tint in gray looks very premium. Although the MIX 4 is relatively average in terms of the back cover design, the production quality is nevertheless superb. The Unibody ceramic body was well received by the public when it first debuted on the MIX 2, and the Unibody process is polished even further on the MIX 4.

With the new technology, the ceramic body is 30% lighter, which is one of the reasons why the MIX 4 is lighter than the Mi 11 Ultra. The back cover and frame are unibody, so it won’t pinch your hand, and it naturally feels much better than other phones. And since ceramic has a greater thermal conductivity than glass, you get the feeling that the MIX 4 will get warmer more easily than other phones with glass back covers. Honestly, the feel of the MIX 4 is really very good, and it’s hard to describe it in words. So If you get the chance, you must go and experience it yourself.

Xiaomi Mi MIX 4: Under Screen Camera Quality

You must also be very curious about the quality of the front camera, right? We were curious too and tried to take a couple of selfies.

Are you happy with its quality? Personally, I’m satisfied with the front camera quality, especially considering there is a screen covering the camera. But if you zoom in, even though the AI processing has optimized the image much more than what we saw in the preview, many details of the image are not visible anymore. So, despite using a new under-screen camera solution, MIX 4 is not recommended for people who want high quality selfies.

But if you want basic selfies or just want to talk to your family and friends on video calls like I do, this front camera can handle such simple scenarios


MIX 4 is also equipped with the Snapdragon 888+ SOC for the first time. With 780,000 points on AnTuTu and 5700 points in 3D Mark, this chip doesn’t feel much different from Snapdragon 888. Because of time constraints, we could only test PUBG on the phone, and with the performance mode on with the HDR Graphics Extreme frame rate mode, it still limits the frame rate. With an average frame rate of 53 FPS, it seems that the MIX 4 is very conservatively tuned for performance.

The MIX 4’s rear camera also takes very good pictures, and performs very well in most cases during the day. But the ultra-wide lens and telephoto lens low light photo quality is more towards average, and the dynamic range is relatively low. The main camera does not have this problem when the night mode is turned on. And the performance in low light is also very good.

MIX 4 also brings the fastest charging combination for cell phones right now. We are talking about 120W wired charging + 50W wireless charging. After turning on Boost charging speed, the wired charging got the battery to full in just 16 minutes, and when using wireless charging, it took 37 minutes for a full charge.

People may wonder how its 50w wireless charging solution can charge the phone in just 37 minutes. This is because, recently, China added a policy stating the power output of wireless charging should not exceed 50w. This policy was officially implemented sometime before the launch. So Xiaomi did not dare to advertise a faster wireless charging solution, even if it technically achieved an output higher than 50w. In fact, the wireless charging power of MIX 4 is much greater than 50w. If you turn off the Boost charging speed function, wireless charging you can only change at a maximum of 50w, and it will take 50 minutes to fill up.

Xiaomi Mi 11 Ultra Appearance

The Xiaomi Mi 11 Ultra is bold enough in design and sufficiently individualized, and it has indeed achieved the so-called ‘differentiation’ in the design of high-end flagship phones.

It has three colors of ceramic black, ceramic white, and marble pattern special edition. We are reviewing the marble pattern special edition. Although this kind of marble texture is made by laser, the look and feel is no different from the natural marble pattern. The marble special edition also uses ceramic processing, which is warm and delicate in hand, softer than traditional glass, and it is not easy to leave fingerprint marks.

There is another change in the details of the Xiaomi Mi 11 Ultra, that is, the original ‘MI’ logo has been replaced by the current ‘Xiaomi’. The font is more rounded and softer, and it applied silver highlights.

The camera module area occupies almost one-third of the back of the phone. When held in the hand, it is more like holding a camera that can make phone calls. The image module is huge. But there are actually only three sensors. Each of them can be called the main lens.

On the right side of the three main cameras, there is also a 1.1-inch eye window. Which you can use for displaying custom pictures, time, weather, animations, themes, notifications, message reminders, health reminders, music control, etc.

In addition, the small window can also display the viewfinder real-time preview in proportion to the main screen when taking pictures. Which is very suitable for bloggers who often shoot vlogs. More importantly, with the ultra-low power consumption of this screen, the Mi 11 Ultra also brings a ‘wilderness survival mode’ to solve users’ urgent need for power in extreme scenarios.

Other Features

Seeing this small screen on the back of Mi 11, many will think of the smart window on the back of the Meizu Pro 7 a few years ago. The smart window you can also regard as Meizu’s exploration of smart interaction.

The rear image module of the Mi 11 Ultra is very prominent. Even if you wear a leather protective case, it still will be bulky. The Xiaomi Mi 11 Ultra has a body size of 164.3 x 74.6 x 8.38mm. It also does not leave the 200g club. For those who are used to thin and light smartphones, the weight of 234g can be very unfriendly. After all, there is a large 5000mAh battery inside.

Back to the front, the Xiaomi Mi 11 Ultra sports a 6.81-inch hole-punch quad-curved full-screen. The parameters are exactly the same as that of the Xiaomi Mi 11 Pro.

This screen has one billion native colors, 20:9 ratio, 3200×1440 WQHD+ resolution, 120Hz refresh rate, up to 480Hz touch sampling rate, E4 luminescent material, 1700nit peak brightness, supports Xiaomi self-developed screen calibration algorithm, JNCD≈0.38, △ E≈0.41. It also supports DCI-P3 display, HDR10+, and Dolby Vision. It has passed SGS low blue light eye protection certification, SGS high-speed display certification, etc. Shortly, it’s perfect. You may say it doesn’t support LTPO, but after all, the Xiaomi Mi 11 Ultra has a large 5000mAh battery. We mean it shouldn’t have serious problems with power consumption.

In the system settings, Xiaomi also provides a very rich color style options, including adaptive, vivid mode, primary color, advanced mode, etc. Advanced mode also provides professional parameters for users to customize settings.

Xiaomi Mi 11 Ultra Performance

In terms of configuration, the Xiaomi Mi 11 Ultra has no shortcomings. Its hardware parameters include the full blood version of LPDDR5 3200MHz, UFS 3.1, Snapdragon 888, X axis linear motor, 5000mAh silicon oxide negative battery, wired and wireless dual 67W flash charging, IP68 waterproof…

The Xiaomi Mi 11 Ultra is the world’s first silicon-oxygen negative electrode super-fast charging battery (5000mAh); wired and wireless fast charging is 67W. The manufacturer said that it can be fully charged in 36 minutes, and it supports 10W reverse wireless charging.

Although the weight of the Mi 11 Ultra is over 200g, the thickness of the body is only 8.38mm. This is mainly due to the use of a silicon-oxygen anode super-fast charge battery. The battery comes with the ‘second-generation’ nano-silicon-oxygen technology anode cell. The battery energy density is expected to be 1000Wh/L. And it uses the nano-silicon particle surface pre-filled lithium technology. In simple terms, for the same volume, it can achieve a larger capacity. The Xiaomi Mi 11 Ultra took 38 minutes to fully charge to 100%. For a smartphone with 5000mAh, this speed is already very good.

Though it comes with both NFC and infrared, we won’t focus on them now.

The Xiaomi Mi 11 Ultra also introduces a very practical configuration. The ultra-thin fingerprint recognition supports a new heart rate detection function. To open the Xiaomi Health app, you only need to gently press your finger on the fingerprint module recognition area for 15 seconds.

The Xiaomi Mi 11 Ultra uses a stereo speaker design, professionally tuned by Harman Kardon. Among them, the top adopts a new customized higher specification 1014 speaker unit. The bottom is upgraded to a 1216P super linear speaker unit with a maximum amplitude of 0.8mm.

Xiaomi Mi 11 Ultra Camera

Don’t look at the huge camera module of the Mi 11 Ultra. In fact, there are only three internal cameras, but all of them are the main cameras. That includes the 50-megapixel ultra-large bottom customized main camera GN2, a 48MP 128 ° ultra wide angle lens, and a 48MP 120X telephoto lens. The three main camera system completely covers the 12-120mm focal length.

The main camera of the Mi 11 Ultra is the Samsung GN2. Its photosensitive element size is as high as 1/1.12 inches, which is very close to one inch. This is the largest base in the smartphone field at present. It is even comparable to the Sony Black Card M7.

The single-size pixels of Samsung GN2 reach 1.4μm, and the four-in-one mode can reach the industry’s largest 2.8μm. The fusion of super-large pixels, outsole + super-large pixels, gives the Xiaomi Mi 11 Ultra unparalleled light sensitivity. At the same time, the lens adopts the same 8P lens as the Mi 10 Ultra. It has an f/1.95 aperture and supports OIS. The Mi 11 Ultra also brings the night owl algorithm. The latter is as low as 0.02Lux illuminance under extremely low light.


The starting price of the Xiaomi Mi 11 Ultra for the Chinese market is 5.999 Yuan. It roughly translates into $914. The Xiaomi Mi Mix 4 starts from $770 and it is a bit more affordable. Overall, the Xiaomi Mi 11 Ultra is a superior device. The Xiaomi Mi Mix 4 is more innovative with its under-screen camera and a better processor. If we exclude the secondary rear display of the Mi 11 Ultra. But the Ultra has better cameras and a bigger battery, so it provides a superior user experience.
