Alleged Xiaomi 18 Pro and Xiaomi 18 Pro Max – 3C Certification
On the 3C certification database, two upcoming Xiaomi 5G smartphones carrying the model numbers M154FF and M311AD have been listed. The devices are manufactured by Xiaomi Communications Co., Ltd., while Lens Technology (Xiangtan) Co., Ltd. is mentioned as the factory. Previous certification appearances have linked these two model numbers with the upcoming Xiaomi 18 Pro series.
Speaking more, the certification lists Xiaomi’s MDY-18-EW power adapter, thus confirms that the two upcoming smartphones will support up to 100W wired fast charging.
While the 3C certification itself does not reveal the monikers of M154FF and M311AD, reports suggest that these could be the upcoming Xiaomi 18 Pro and Xiaomi 18 Pro Max, respectively. Notably, M154FF had earlier also appeared on China’s SRRC certification database, revealing N79 5G band and UWB support, with the model being tipped to belong to the Xiaomi 18 Pro.

Coming to their expected specifications, previous rumors claim that the Xiaomi 18 Pro could feature a compact 6.3″/6.4″ display and may be powered by Qualcomm’s upcoming Snapdragon 8 Elite Gen 6-series flagship chipset. The smartphone has also been tipped with two 200MP rear camera sensors, including a 200MP main camera and a 200MP periscope telephoto camera, along with another ultra-wide-angle sensor. A battery of around 7,000mAh and 100W wired charging support have also previously been tipped.
The larger Xiaomi 18 Pro Max, on the other hand, is rumored to arrive with around a 6.9″ display, while it is also expected to use Qualcomm’s next-generation flagship Snapdragon chipset. Previous reports have further pointed towards a camera setup featuring 200MP main and 200MP periscope sensors, along with an ultra-wide-angle camera. The Pro Max is also tipped to pack an 8,000mAh-class battery.
Furthermore, both the Xiaomi 18 Pro and Xiaomi 18 Pro Max are expected to continue featuring a secondary display on the rear, similar to their predecessors, although reports suggest that Xiaomi could make the secondary screen more versatile this time around.
With the alleged devices now picking up certifications, more details regarding the upcoming flagship smartphones could possibly be revealed in the coming days.
