REDMI released the first issue of “Turbo 4 Pro Answers Netizens’ Questions”, answering the three issues that everyone is concerned about: reverse fast charging, metal middle frame, and screen.
In response to the question, “1000 yuan phones ten years ago all had full metal bodies, so what’s so great about a 2000 yuan phone with a metal frame?” REDMI said, “Yes, it’s true. The two are completely different.”
REDMI said that the thousand-yuan phones ten years ago did use an all-metal body design. Although it seemed to be a relatively high-end material at the time, it is fundamentally different from the current metal middle frame structure.
Most of the thousand-yuan phones at that time adopted the “top and bottom cover” structure which was popular at that time. The back cover was a stamped metal cover with good texture but it did not play a big role in strengthening the structure of the whole machine.
Simply put, it can be understood as “metal skin”.
Most mobile phones now use a “sandwich” structure, and the middle frame is the core of the structural strength of the entire machine, which can be understood as a “metal skeleton.”
It is reported that the metal middle frame of Turbo 4 Pro is made of CNC one-piece processing, and its rigidity is 140% higher than that of the conventional MDA structure middle frame. When the same external force is applied, the deformation is smaller, and it is harder and stronger.
In addition, the bending strength of the Turbo 4 Pro reaches 700N. According to official tests, it can withstand the 70Kg weight of Wang Teng, general manager of the REDMI brand, and it can still be used normally after being taken down.
REDMI said that the cost of the metal middle frame is much higher than that of the MDA middle frame, and the cost of a single unit is 250% higher. Therefore, the metal middle frame generally only appears in the flagship models of various companies and is quite rare in the 2.5K range, so it is still worth talking about.
