We are therefore going to analyze the characteristics and the technical sheet of the Xiaomi Mi MIX 4, a top of the range that lacks nothing and that shines mainly by its design and its power. Here’s everything you need to know about this phone.

Raw power and under-screen camera

The Xiaomi Mi MIX 4 is a high-end device with a 6.67-inch panel equipped with AMOLED technology, Full HD + resolution and a refresh rate of 120 Hz. This generation does not make the jump to 2K, as seen in some members of the Mi family, like the Mi 11 Ultra.

The most important thing about this panel is that we can’t find any perforations or notches of any kind, and that is that the camera is hidden under the screen. This makes the terminal have a very well used front panel (albeit with a very slight chin), without distractions of any kind.

At the hardware level, the Xiaomi MIX 4 has the latest addition: the best Qualcomm processor and 12 + 512 GB of internal memory

At the hardware level, the Xiaomi Mi MIX 4 comes with the latest: Qualcomm Snapdragon 888+. It also has configurations of up to 12 + 512 GB of memory, starting with 128 GB of internal memory and 8 GB of RAM.

To power it, we find a 4,500 mAh battery with a fast charge of 120 W and a wireless charge of 50 W, figures of a real scandal to charge the mobile in just a few minutes. Concretely, it is able to charge the phone from 0 to 100 in 28 minutes, although by default it does so in 45 minutes so as not to damage the battery so much.

108 megapixels on the back

On the back, the Xiaomi Mi MIX 4 is quite reminiscent of the Mi 11 Ultra, since it has a gigantic module with several cameras. The main one is a 108-megapixel Samsung sensor, accompanied by a 13-megapixel ultra-wide angle and an 8-megapixel telephoto lens.

This telephoto lens lets you zoom optically up to five times (up to 50 times digitally) and has physical stabilization so photos don’t shake. The front camera is 20 megapixels and, as we said, it’s hidden under the screen.
