Xiaomi’s Mi Mix series is a pioneer of note, emphasizing on bringing slick designs to the table. It’s been more than four years since the last commercially available Mix product, but Xiaomi is now back with the Mi Mix 4.
The biggest USP of this phone is the switch to a 20MP under-display selfie camera (0.8-micron pixels and 1.6-micron pixel binning). It signifies the first Xiaomi phone with this technology. This might be the first Xiaomi phone with under-display selfie camera then, but the company says this is actually its third-generation tech.
The company offers a ceramic back, departing the glass and a throwback to devices like the Mi Mix 2. You will find the phone in Ceramic White, Ceramic Black, and Ceramic Gray color options.
Xiaomi Mi Mix 4 – What’s under the hood?
This new Mi Mix device comes with some great core specs otherwise, featuring a Snapdragon 888 Plus processor, 8GB to 12GB of RAM, 6.67-inch FHD+ curved OLED screen (HDR10+, Gorilla Glass Victus), and 128GB/256GB/512GB of storage.
It also has a 4,500mAh battery with 120W wired charging and 50W wireless charging. It reaches a full charge in 21 minutes via wired charging and 45 minutes via wireless charging. In addition, Xiaomi also touts a so-called Boost Mode, offering wired charging of 15 minutes and wireless charging times of 28 minutes.
Mi Mix 4 price and availability
Xiaomi’s latest phone starts at 4,999 yuan ($771) for the 8GB/128GB model, 5,299 yuan ($817) for the 8GB/256GB model, 5,799 yuan ($894) for the 12GB/256GB option, and 6,299 yuan ($972) for the 12GB/512GB option. It also states that this is a “Mainland China device only.”
Compared to the first generation, the MIX 4’s design is somewhat less noticeable. Like many other smartphones, there is a matrix rear camera in the upper left corner. The new gray color scheme is elegant, and the blue tint in gray looks better. It is relatively average when it comes to the back cover design. The Unibody ceramic body was popular amongst the public when it first launched on the MIX 2, and the Unibody process is polished even further on the MIX 4.
The ceramic body is 30% lighter due to advanced technology, this is the reason MIX 4 is lighter than the Mi 11 Ultra. The back cover and frame are unibody. It will go smoothly on your hand and you will feel much better than the other phones. The feel of the MIX 4 is really very good, and it’s hard to describe it in words.
Xiaomi MIX 4 Camera Quality
You would be curious about the quality of the front camera, right?
Personally, you would definitely be happy with its camera quality considering there is a screen covering the camera. But if you zoom in, even though the AI processing has optimized the image much more.
Many details of the image are not visible anymore. So, despite having a new under-screen camera solution, MIX 4 is not the phone for people who want high-quality selfies. But you can get basic selfies or if you want just to talk to your family and friends on video, this front camera can handle such simple scenarios.
Hardware, Camera, & Battery
Having been equipped with the Snapdragon 888+ SOC for the first time, it has 780,000 points on AnTuTu and 5700 points in 3D Mark. This chip isn’t much different from Snapdragon 888. With an average frame rate of 53 FPS, it seems that the MIX 4 is very conservatively designed for performance.
The MIX 4’s rear camera is also very good for pictures. It performs very well in most cases during the day. But the ultra-wide lens and telephoto lens low light photo quality are average, and the dynamic range is quite low. The main camera does not have this problem when the night mode is turned on. This makes the performance of the camera in low light quite good.
It runs Android 11, with the company’s MIUI software on top. Mix 4 has started selling in Australia also from August 2021. Xiaomi’s software is lively, colorful, and packed with whimsical animation.
The one-hand mode only works with on-screen button navigation and not swipe gesture navigation. Considering the latter is the standard in smartphones, this means the phone doesn’t really have a one-hand mode.
The Mix 4 overall perform quite well. The Snapdragon 888+ is the best chip for an Android phone right now, and the phone zips around with ease no matter how much you push it. Battery life is great, as the 120Hz screen eats a lot of power—on a weekend day out around town you can use the phone often for photos, videos and social media, the Mix 4 drained about 12% of battery per hour. It means, it will not last even 10 hours outside. But that’s when you use it heavily. For normal use which is 12-14 hours, it is a great phone.
The best part is the Mix 4 includes s 120W charging brick in the box. Charging at this speed is amazing, as a 10-minute top-up will add roughly 40% of battery. So, as long as, you have time for even a five, six-minute charge in the middle of the day the phone should be guaranteed to last you an entire 15-hour day outside.
This phone also supports wireless charging up to an insane 100W speed provided you buy Xiaomi’s official charger.
The haptics and speakers of this phone are superb and among the best in the industry. These are two areas that Xiaomi has really nailed in the last two years.
There are people who find the entire premise of under-screen cameras to be overkill and unnecessary, especially since Android flagships today are already almost entirely screen, with only a tiny hole drilled into the screen to accommodate the selfie camera. For some, sacrificing selfie camera quality just to gain an extra 0.5% of screen space is not acceptable.
