A large number of Xiaomi Mi 11 Ultra specs have leaked, showing off a unique secondary rear screen and 120x zoom.

Phones with multiple screens already exist, especially in the foldable phone space. But this range-topping Xiaomi smartphone is aimed at more conventional flagship phones like Samsung's Galaxy S21 Ultra and iPhone 12 Pro Max. And neither Samsung nor Apple can compete with this.

All of these details and images are from a YouTube video published by Tech Buff PH. His video has been taken down, but thanks to XDA Developers and YouTube Mirror, you can still see the screenshots.

You can't miss the huge rear camera bump on this phone. Not only is there a large camera lens, but there is also a small display on the right side. This mirrors the main display and can show whatever you want it to show.

However, the original use of this display seems to be to take selfies with the rear camera. Or to see what the subject looks like before pressing the shutter button.

The three cameras, consisting of a 50MP main sensor, a 48MP ultrawide sensor, and a 48MP telephoto sensor, appear to have up to 120x zoom, according to the label next to the sensor. The optical zoom on this sensor is expected to be 5x or 10x. There is one 20MP camera on the front.

Tech Buff also shows some other specs in his video. It has a 6.8-inch display, the same size as the regular Xiaomi Mi 11, but with IP68 water resistance and a 5,000mAh battery.

It has the option of 67W wired charging or 67W wireless charging, which is faster than the basic Mi 11's 55W/50W capabilities. There is also reverse wireless charging of up to 10W.

Like the Mi 11, the Ultra model has an adaptive 120Hz refresh rate 2K QHD display with Gorilla Glass Victus. Underneath is a Snapdragon 888 chipset and stereo speakers tuned by Harman-Kardon.

The Mi 11 Ultra certainly lives up to its Ultra name and is packed with all the technology. It doesn't have as many cameras as Samsung's Galaxy S21 Ultra, but the quality of the sensors on board, and that odd secondary screen, may mean that the Mi 11 Ultra has what it takes to be one of the best camera phones. [But we'll give you more specific impressions once we get our hands on the Xiaomi Mi 11 Ultra.
