In previous weeks, several sources have confirmed that Xiaomi will hold a launch conference around mid-August in which it will unveil some products including the upcoming Xiaomi Mi MIX 4.

Xiaomi Mi MIX 4: new variants nabbed on TENAA, will support UWB technology

As we know, the Xiaomi Mi MIX 4 was already spotted on a Chinese certification site about a month ago. Today, a new leak shows us that the brand has added two new specifications within the certification. Namely, that the smartphone will be available in at least two memory variants with 8GB of RAM and 256GB of storage and 12GB of RAM, again with 256GB of internal storage.

At the same time, well-known blogger Digital Chat Station revealed that the smartphone codenamed K8 (the Mi MIX 4) will bring some unique features based on UWB technology, a non-inductive and directional transmission method between devices that will present a new method of interaction.

UWB technology is a new generation of connection technology for positioning in space. The full name of UWB technology is Ultra Wide Band communication. It has a bandwidth of 500 MHz to transmit data and has the characteristics of strong anti-interference capability, high transmission speed, low power and high accuracy. It can be used for high-precision indoor positioning, interaction with Internet of Things devices, file transfer and other application scenarios.

UWB can also greatly improve the ability of spatial perception between devices. Apple has already equipped this feature for iPhone 11 series devices.

Xiaomi also officially announced its UWB technology in October last year and demonstrated a smartphone that can be pointed at the device to control it.

As for the other specifications, apart from the large amount of 12 GB RAM, the Xiaomi Mi MIX 4 will also have top-notch performance. In fact, it has been reported that the device will feature the Snapdragon 888 Plus processor.

The Xiaomi Mi MIX 4 will also bring a high-end configuration on the charging side as well. Several leaks have it coming with.

worth mentioning that the Mi MIX 4 marks a return to basics for the Mi MIX series. In fact, it will be a device with a primary focus on the full screen design of the front. This will be achieved thanks to a state-of-the-art under-screen camera.

As for the rest, the Xiaomi Mi MIX 4 will feature a 6.67-inch unperforated curved display provided by TCL Huaxing. However, due to the limitation of the camera technology under the screen, it does not come with 2K resolution like the Xiaomi Mi 11 series does, instead it only supports 1080P.
