According to Xiaomi, the Mi 11 Ultra will feature new battery technology and a revolutionary cooling system. Apparently, the so-called phase-change cooling system contains solid, liquid and gas parts to deliver significantly better cooling performance than contemporary Xiaomi smartphones.

The last few days have already shed a lot of light on the Mi 11 Ultra, Xiaomi's upcoming flagship Mi 11 series smartphone. Xiaomi will be unveiling the Mi 11 Ultra tomorrow alongside a host of other smartphones, including the Mi 11 Pro and the first Mi Mix series device since 2019.

The company has already revealed that the Mi 11 Ultra will feature a new battery technology, which supposedly is considerably denser than the Lithium-Ion cells used in contemporary smartphones. However, it has now confirmed that this battery technology will work in tandem with a 'revolutionary' cooling system. Several Weibo posts explain that this system uses 'phase-change cooling' to deliver up to 100% better thermal conductivity, although Xiaomi would not reveal to what it was comparing its new cooling method.

Apparently, this cooling system uses solid, liquid and gas elements to cool the Mi 11 Ultra, and the notoriously hot Snapdragon 888. In our opinion, Xiaomi's supposedly revolutionary cooling system sounds like a vapour chamber combined with several metal elements to dissipate excess heat. With that said, the Mi 11 struggled to keep the Snapdragon 888 cool in our tests, so any additional cooling performance could give the Mi 11 Ultra the edge over its cheaper sibling.
