The Xiaomi 11T Pro has proven to be a heavyweight, the worthy successor to the Mi 11 family, already emancipated from its “mi” prefix. Its milestone in fast charging, a direct inheritance from the Xiaomi MIX 4, and its imposing screen have made it one of the smartphones of the season. But maybe more than meets the eye in its construction.
In order to rate its repairability, the PBKreviews team disassembled and reassembled a Xiaomi 11T Pro, encountering a monumental surprise: a large strip of graphite mounted on the battery that seeks to cool and dissipate heat from the entire central body of the terminal.
Graphene, the ally of the Xiaomi 11T Pro
During the disassembly process we can appreciate several very interesting details. After removing the first set of screws (13 in total) and removing the camera module housing, just below you can see a wide strip of graphene film, very thin and responsible for displacing residual heat from the inside to the outside.
This layer is located just above a battery that is actually two. Another trick of the master is that the 5000 mAh battery with 120 W fast charging it is actually two slots of 2500 mAh each. In the video you can see a central notch, a fault between both batteries interconnected under the legend A and B.
The teardown shows that some copper sockets —Of, we suppose, a high-density alloy— connect to this strip of graphene by means of heat conduits, those micro-TTBs (basic thermosyphon tubes) of perfect geometry that we can see on the pumpkin-colored sheet.
Towards minute 4:10 and once this floor has been disassembled we can see a good layer of thermal paste applied unevenly to the dock of the SoC, the “rib cage” of the terminal.
Like all SoCs at full performance, the Snapdragon 888 processor can reach quite aggressive temperatures. However, Xiaomi has already tamed this SoC through its custom ROM, MIUI. Using software, they have managed to reduce their temperature by 5ºC while maintaining their nominal performance.
In conclusion, the sum of these components protects and dissipates excessive heat from the upper third of the terminal to the rear and lower margins of the smartphone. A clear emphasis and a conscious effort to prevent the 11T Pro from overheating and it may damage components such as the screen or camera sensors.
