Huawei will reintroduce the Mate series in September. HarmonyOS 3.0, a new chipset, and potentially the Aito M5 EV or Aito M7 will accompany the Mate 50 series.

The Mate 50, Mate 50 Pro, and Mate 50 RS will be included in the series. The phones will be powered by the new Kirin 9000S CPU, which reportedly only supports 4G.
The render below, courtesy of the trusted Chinese site Digital Chat Station, shows the purported back design of the Mate 50 and Mate 50 Pro.

This graphic allegedly depicts the distinction between the Mate 50 and the Pro (and likely RS). The standard model has a punch-hole camera, while the Pro model includes facial scanning.
Along with the Mate 50, Huawei will unveil the new Harmony OS 3.0. According to rumors, there will be some image enhancements dubbed XMAGE.
