One of the most unique features on the Mi 11 Ultra is its rear 1.1″ AMOLED display, which differentiates it from the rest of the smartphones in the market. However it does share one major similarity with one of the more affordable devices Xiaomi sells, the Mi Band 5. Lei Jun reportedly shared that the Mi 11 Ultra uses the Mi Band 5’s display as its rear-facing screen.

It’s quite interesting that the display from a smart band can be reused for this purpose in a smartphone. The Mi 11 Ultra’s secondary display can be used to display the time in AOD mode, and can even work as a viewfinder, if you somehow decide that you need to take selfies with the rear camera.

Repurposing the Mi Band 5’s display for this should have helped lower the production costs of the Mi 11 Ultra. With that said, it is still a rather pricey RM4299, so I can’t exactly imagine how much more expensive it would be if Xiaomi decided to order a different batch of screens for the Mi 11 Ultra’s secondary display.


I am also quite interested to see how well will this secondary screen handle its job as an AOD, considering that the Mi Band 5 never offered the AOD functionality to conserve battery. Will burn in set in faster than on the regular AMOLED displays we have on our devices?

The Mi 11 Ultra’s specifications are as below:

While the Mi 11 Ultra is the most expensive smartphone Xiaomi has ever brought into Malaysia officially, it does still live up to Xiaomi’s motto of honest pricing. Too bad that you might not get to buy it here in Malaysia officially anymore, as the pre-orders sold out in less than a day.


Pokdepinion: I do look forward to all kinds of funky things that we will see Mi 11 Ultra users do with their rear screens!
