With two weeks left until the end of September, Xiaomi is starting to reveal its cards. The company released a short teaser for the upcoming Xiaomi 18 Pro series, showing the back of the phones. Don’t expect major changes — but one subtle detail is worth noting.

Secondary Display Remains, Bezels Shrunk

The most prominent feature of the previous generation was the secondary display on the back, and Xiaomi is keeping it now. The difference is that the bezels around it have slimmed down compared to the 17 Pro model. The Leica logo has moved to the right, and otherwise, the back remains essentially unchanged.

The Button Xiaomi Is Silent About

On the side of the phone, another physical button is visible in the video, about whose function Xiaomi has not said a word. According to several independent leaks, it is supposed to be an artificial intelligence button, linked to the company’s agent Miclaw and — importantly — programmable, not hard-assigned to a single service.

It’s worth recalling history here. Samsung once added a button for Bixby and became a target of ridicule because it couldn’t be remapped. In contrast, the action button on iPhones caught on precisely because everyone could customize it to their liking. So, if the leaks are accurate, Xiaomi is taking the more sensible path.

This Time, Also for Us

And now for the most important news for European customers. While the Xiaomi 17 Pro and Pro Max remained Chinese exclusives, the 18 series is expected to have a global launch, according to available information. The company sold over five million units of the previous series in China and aims to replicate that success elsewhere.

The remaining leaks suggest a 6.9-inch flat OLED with a minimum brightness of one nit for night reading, a battery of up to 8,000 mAh compared to the current 7,500, and a pair of 200Mpx sensors — main and periscopic. They are expected to be powered by the Snapdragon 8 Elite Gen 6 Pro, manufactured with a 2nm process. The base Xiaomi 18 model is expected to be unveiled in December, while the Ultra version has reportedly been canceled. However, everything except the teaser currently comes from leaks.

Does a secondary display on the back of a phone make sense to you, or is it unnecessary?
