Thermals and signal enhancements (Pro+ specific)
The Note 15 Pro+ introduces an advanced cooling design with an ice-sealed circulating cooling pump and a 5200mm² ultra-large heat dissipation area, with combined thermal conductivity claims up to 5954mm² and a dedicated mid-frame graphite area. The Pro+ also includes Xiaomi’s Pascal T1S signal enhancement chip to improve network stability and reception in challenging environments.
