Xiaomi founder Lei Jun said in a post that we were a little worried in the early days of the Xiaomi 12S series, but now I feel a little more at ease. It is reported that the Xiaomi 12S series consists of three models, including 12S, 12S Pro, and 12S Ultra. The three models have a positive rating of 98% in JD’s self-operated flagship store and are currently one of the best-known Xiaomi flagship products.

Among them, the 12S Ultra is the most concerned, this is because Xiaomi first commercialized many new technologies on the 12S Ultra, such as the 1-inch super outsole IMX989.
This sensor has a full 1-inch super outsole without any cropping. Compared with the iPhone 13 Pro Max, the photosensitive area is increased by 172%, the photosensitive capacity is increased by 76%, the photo-taking speed is increased by 32.5%, and the startup speed is increased by 11%.
Lei Jun revealed that this time Xiaomi and Sony jointly developed the IMX989, the development cost alone was 15 million US dollars, and Xiaomi and Sony each paid half. This is Sony’s largest mobile phone image sensor so far.
Moreover, Xiaomi 12S Ultra also has a leaf vein cooling pump system for the first time. Engineers refer to the water absorption method of plant leaf veins, and ingeniously designed a series of dedicated liquid return channels inside the leaf vein cold pump, like a high-speed lane.
The cold end is “pumped” to the hot end, changing the previous disorderly backflow into orderly high-speed transportation, which greatly improves the cooling liquid circulation speed.
This makes the thermal conductivity of the leaf pulse cold pump system 100% higher than that of the VC soaking plate, which can greatly reduce the internal core temperature and allow the Snapdragon 8+ to run “cool”. In terms of price, the Xiaomi 12S starts at USD 591, the 12S Pro starts at USD 694, and the 12S Ultra starts at USD 887.
